ReattaTType

The first motor is the RWD motor and proper, matches the stock photos. Second picture you are looking at I believe may be the set up for the 3.8L Turbo 6 in the FWD Turbo Reatta prototype. Not where the intake is located and throttle body out the passenger side of the motor, otherwise would be the rear in the RWD application. The Turbo RWD prototype has the intake from front of motor into plenum.

The motor on the left is easily identifiable as the last motor in your pictures. The motor to the right appears to be a twin turbo Tuned Port 5.7L v8 the company also built. Maybe that has turned up in your warehouse as well?

How many engines and parts are in this warehouse? I am not too old but I know the company that has built these motors and have seen pictures! I thought they would have been long gone! The 3800 with the eaton supercharger is a pre-Series 1 Supercharged 3800 motor, the experimental motor prior to 1991 when the Series 1 Supercharged finally came out. I have only seen one stock picture of it before and imagined how period correct it would be in the Reatta or Lesabre T-Type. I am staying in the Troy area next weekend for Motor Muster and Eyes on Design car shows in Detroit. I would love to take a look at these if at all possible and hopefully share the bit of knowledge I know. Any other motors there too would be interesting to see. The company built experimental turbo motors for Dodge, GM in Troy and later did Subaru concepts. The company still operates but when I messaged them for RWD Reatta info they did not reply. They would have built the RWD Regal and Turbo Wagon we saw in the Autoweek video as well.

I can tell you that I have not ordered from his service yet, however, I am planning too. Just never had a full need since we have a similar service in Canada. However, I can say that I know Christo at Allied Vaughn personally and have visited one of their facilities, they do excellent work and everyone there are great, knowledgable historians who love cars and love talking to owners about their cars. Most will go the extra mile to ensure you get the highest quality available. As for the site, General Motors contracts out to Allied Vaughn for their GM Media Services as they are one of the best in the business for media reproductions, etc. The GM headquarters has nothing to do with this and Allied Vaughn location may serve as just a hub itself. The microfilms and media archives are in Sterling Heights.

I have been having a problem with my Reatta since about last October, the fuel pump fuse repeatedly blows. It first happened in 2010 but turned out it was a short of a wire hitting my cold air intake. Last year however it would happen, I would drive a bit and then it would blow again. Putting a new fuse and limping it home worked, however, it finally gave out right in my neighborhood and I rolled the car down the road home. A few weeks after that, I was able to start the car and run it, move it around, however, it blew at the bottom of my driveway. Made it back up into the garage and the car hasn't started since. Turning the key to run blows the fuse instantly, even a 30 amp. I have checked for any shorts in the system in the engine bay found nothing. Now I have gone to check the fuel pump relay to see if it is bad. However, I have read 3 different relay/fuse diagrams now. The back of my relay cover door shows no fuel pump relay or fuel pump fuse. My owners manual shows a fuel pump relay where the courtesy light relay is, and another diagram for 88s shows that there is a fuse, however mine just has two headlamp fuses, mirrors, and defog. Is there something I am missing or were things printed wrong on 88s? I am just wondering if I can get any opinions on what to check next. Ignition 1 fuse is fine, am I missing a relay? I still have yet to check the wiring at the pump or oil pressure switch. Thanks, David Also, this is the Reatta with the supercharged swap and OBD2 conversion, however, everything else seems to be working and reading fine.

The EV-1 and EV-1 cutaway are both still at the GM Heritage Center along with the Impact Concept car. There are many EV-1s that sit in museums all over the United States, Smithsonian is another museum. These vehicles however are disabled and battery packs removed. The only running vehicles that still exist are a rumoured running EV-1 in Arizona and a running EV-1 in the Detroit area that is usually seen around 10 Mile in Warren. This EV-1 is different from the EV-1 in the Heritage Center which also has its running gear. Many were also disabled and sent to schools alike the Reatta. A school in Arizona or California I believe had gotten one of the EV-1s and has since made it run again. However, it cannot be titled. The only one I have seen in private ownership is the 10 Mile EV-1, I have seen it on two occasions despite I live in Canada. My guess would be a GM engineer who had decided to keep the car. The discontinuation letter for the Reatta says that the Reatta met sales figures for the first two years, but let down for 1990 and 1991. The plant was then being used for the EV-1. Afterwards ASC had access with GM to the plants to build the Cavalier/Sunfire convertibles and then the SSR. From what I know the plant was an old Oldsmobile engine plant, then Reatta Craft Center, EV-1 Craft Center then a GM/ASC production facility.

Unfortunately the gas door is open and broken. Just haven't gotten around to repairing it just yet, too much fun driving around. Thanks too all though and yes the car is black.

It is that time of year, the time for the colors to change, the leaves to fall, and up here in Ontario, only a few weeks left until the Reatta goes into hibernation and surgery for the 6-speed. I live in an area called the Niagara Escarpment, in which we are fortunate enough to have such an elaborate landscape. To me, this means photo ops of the Reatta and the scenery. Here are some of the pictures I ended up with. So lets see who else has been out to enjoy the fall in their Reattas.

The old location is now a center that houses a few community services, such as welfare, language classes, and some other services. ASC is located about a mile down the road across from the General Motors Technical Center. I have always found it interesting that the ASC Design Center is located on Chicago Road along the NorthWest side of the Tech Center property. ASC has always been a large part of operating with General Motors on certain projects, therefore, the close proximity makes sense. A man I met last year on a project worked for ASC for many years and was there when the GNX was engineered as well as the Reatta convertible. He always referred to the Reatta as the Riviera convertible however. He was in a reasonable position at ASC from what I recall and also worked with General Motors on the SSR. He now owns his own company building new thirties Ford bodies and parts. As for the design and development of the convertible through ASC, I unfortunately did not ask, though he does remember the project. They would have had a few prototypes at ASC themselves for fitment and design mock-ups as GM did not do many convertible sketches and renderings, just a targa from pictures.

All 17 1990 Reatta Coupes that were imported to Canada had 16-way seats, as for convertibles I am not sure how many of the 60 had 16-ways, I saw the stat sheet but it slips my mind at this point.

Hello everybody. Sorry about the late reply so soon to the cruise but who on the site is planning on visiting and having their Reattas at the Woodward Dream Cruise this year. The event is this Saturday on Woodward Avenue in Detroit. I am going to have my supercharged Reatta down for the cruise. Would anyone on the site attending with their cars be interested in a convoy on Saturday morning down to the cruise and then a dinner/meet-up on the Saturday. I am inviting David McIntosh to dinner as well, the Reatta designer and GM chief designer so we will see if he can make it as he has his Reattas as well. If anyone is interested in the convoy. Would organize and start heading off at 8 am from the Marriott hotel on Centerpoint Parkway in Pontiac. The hotel is only a few minutes from M-59 and right off I-275 I beleive, just off of Opdyke Road. The road leads directly to Woodward and would allow us to convoy easily through the busy areas connecting. If anybody is interested please reply here or give me a call at 519-942-6860. (The hotel is also site of the GTO Club of America meetings/show and shines. Every year they average at least 90 GTOs and on a good year 150 cars with a show on the Sunday morning. So if you like GTOs as I do, this is the place to check them out. Vendors are also at the hotel, great if you hae an old Pontiac to restore and need parts.)

The swap is a great swap as I have completed it. Very much easy to change the engine over, however I kept my stock transmission as I am swapping in the 6 speed manual this winter. I swapped in the Series 1 Supercharged L67, however I am running an OBD-II system in my 1988. If you just want a good cruiser with some additional pep, this engine will be perfect. If you want slightly more improvement, switch to the 94-95 Supercharger and intake manifold. This Eaton M62 was ported from the factory and also features a smaller pulley and a revised intake manifold design over the 91-93. This was good for an extra 15-20 hp if I remember correctly. However, if you want the option with more aftermarket, the Series 2 is ideal with some modifications to keep it OBD-1, knock sensor is one of them. OBD-2 can be done, but requires some tedious wiring. Also use the 98-02 computers in that case, a 97 W-body should be avoided as its computer is problematic and slightly different to the 98. It simply will fry itself during tests. As for the LS4, its tight but it would fit. Has decent aftermarket but the transmission is quite heavy and axles would be difficult as mentioned, I would imagine having to use different wheel bearings to allow larger diameter axles. Also it is a newer engine that requires more fabrication and is fairly pricey to pick up. Wouldn't recommend it unless you wanted a serious swap. And finally the Northstar, while the first gen Northstar was quite horrendous and I personally wouldn't bother due to reliability concerns, overcomplicated maintenance such as the starter, and no aftermarket. The 2001+ Northstars are actually quite good and more reliable than earlier, they still can have some lemons. While the Northstar was pretty bad it allowed GM to compete with import luxury using smaller displacement to create higher power numbers. The engine was also designed to be lighter and easier to package in slightly smaller vehicles. As many might or might not know, Cadillac's fate was in question at around 1991/92 and it was discussed that Cadillac could be axed. The 92+ STS' success helped keep Cadillac on the table and in the roster. Largely also due to the new tech introduced in the Northstar package after the 4.9 was phased out. Large RWD Caddy's lacked a business case and couldn't compete, the Northstar helped usher in competitive FWD packaging. Long term it did have its problems though I know some who like their Northstars.

Back to the article, that car is in no way a representation of anything General Motors did in terms of the design. These renderings are meerly speculation done by a magazine artist of what could be possible. Hence why all renderings have the same signature. As many of you may know, the final design was reached at around 1982 with some modifications made at around 1984. By 1985, the date of this article, full prototypes were running around Milford Proving Grounds and 1986 issue of Autoweek shows a white prototype being tested on public roads with no hood emblem but other insignia taped off. It wasn't a case of GM didn't continue it design wise, they just didn't entertain keeping the Getrag transaxle or the Reatta T-Type proposals. The problem with some design aspects on these cars however was that GM engineers took over after 83/84 to make it production ready. This is why pictures can be seen at about 1985, a Reatta wearing Buick Tri-shelds, cloth seats, and wire wheel covers. That being the focus group car, then the proving ground prototypes wearing light driftwood paint, dark interior, and 1991 Park Avenue "turbine" wheels with different center caps at around late 1985. Some aspects such as the wire wheel covers and Buick insignia was used as engineers didn't know how to market and place the car, and the name also came mid-way through development. The closest vehicles mentioned to this article were the Turbo prototypes, Indy Pace Car, and Chuck Jordan's personal Reatta which sported a body kit, special light blue paint, and no muffler. Of which, only the Pace Car survives today sporting the body kit reminiscent of the idea of a sportier Reatta. Supercharged could have been offered, yet the engine simply wasn't ready in time as it came out in 1991. GM had little previous experience with production supercharged powerplants, but lots in turbos, hence the prototypes. However, why put a new breed of engine in a car that was already destined to be axed. And it also wasn't until 1989/1990 that the ZR1 came out. Before that, the Corvettes marginal performance would easily be intruded by a forced induction 3.8, the choice why GM couldn't develop a business case for what appeared in that article as a manual or a higher performance model. It was indeed on the table very early, but of course led to rumors and speculation. It still happens today with the C7 Vette mid-engined rumors. It was played around with in every era, but no business case could be made and still can't be. With GM axing certain performance programs, it all leads back to the fact that sales would eat into yearly sales of America's icon, the Corvette. That led to the Firebird/Banshee not being a two seater in 1967, the Fiero program being axed after its first generation (also due to the Firebird), and the supercharged Escalade not being produced as Bob Lutz has mentioned, it would eat into about 80 or so Vette sales a year. Few products came out of GM that outperformed the Vette; GNX, 86/87 GN, Syclone/Typhoon to name some, although the GNX and GNs were axed due to the platform change. Just a rant that describes GMs ideaology in terms of why some projects don't happen. (Also, the Reatta was also supposed to have smaller bumpers seen on the clay "targa" model, but to sell in Canada, 5 MPH bumpers were required so they were extended. After the Reatta sold about 800 units in Canada throughout the 4 years, was it worth the change?)

Thanks Ronnie, not exactly what I am looking for but I am playing around with the idea of routing it there, problem being the piping comes too close to wires and the headlight itself. There is an area just below that I felt might work, requires me to remove the windshield washer jug and relocate that. It is just below the snorkel there though. I figured if anybody had pictures while their car was stripped for paint or accident repair maybe. Thanks again though Ronnie, The Reatta is a bit tough for the routing because I don't want to touch the rad, etc.

I am now looking at routing an intercooler for my supercharged swap. Its a Series I L67 and they create a lot of heat as I am looking at creating more power. Supercharger pulley I have but the engine just runs too hot to be as efficient in creating power as i'd like. I am just wondering if anybody has a picture of their car without the front bumper on it and if the headlights were removed that is perfect too. My car is a daily driver as well so I am not able to just remove the bumper and lights at any time. An intercooler will sit perfectly between the front bumper and rad, but the piping is the issue. I think I may be able to work it through a space in the front subframe, but it needs to be bigger which I can fabricate. Its under the snorkel on the drivers side. If anybody has any pictures that would be great. Thanks.

Yesterday I had to get towed back as I had an electrical problem that caused me to be stranded on the side of the highway. First I lost the touchscreen, then the digital dash gauges and all, yet my trouble lights still worked. My touchscreen would go on and off as well as the gauges, everytime causing the radio to turn off too. I tried to push it to get to a certain exit but my car started bogging causing me to pull over and shut it off. The car would not turn back on, no lights, car wouldnt even crank, no power door locks, only hazard lights, got it towed back and right after it got in the driveway. I wanted to check it out, key in, gauges and touchscreen worked fine and car started up, a little bit slower than usual but not much after. Any ideas? I wouldn't believe alternator, its a new Bosch unit and battery levels are always about 13.4 volts, battery connections were fine. Whatever happened, it made the car go into safe mode and not start or anything. I was thinking BCM or CPS but not sure, could they send a surge that could tell a car to shut down, not immediately and then go into safe mode? Thanks. Also the car is not stock but this shouldn't affect it. The PCM is from a 2002 GTP but is connected properly and tuned properly with all connections still fine. Hence why I am lead to believe the problem lies in the BCM or CPS as the touchscreen and gauge cluster went out prior. Thanks.

Same thing happened with my Reatta. However, my engine is a 1995 Series One supercharged and it is the tensioner that is bad. Dayco brand tensioners I have had no issues with and I worked with auto parts for quite a few years, never a single issue. Dayco is one of the last remaining brands making these that I would trust as looking at many over the past five years, their quality has remained excellent. Delco tensioners are alright, however, I do believe they may have started contracting out cheaper. I have heard a few people having a pulley gone on the tensioner not 1000 miles after purchasing it and one or two cases saying the tensioner felt it had a bit too much slack, leading to the belt departing.

Welcome to the forum, I too am in my early 20s and it is great seeing the younger crowd getting interested in Reattas. I have an 88 supercharged Reatta and a 90 Reatta coupe. Alike what you said about your father, my father has had a rough time as well with divorce and a hernia operation. I'm currently working on fixing up my 90 to give to my father as I see him looking at it every once in a while, I know he wants it. A hobby car is excellent as an escape when the hard times kick in. Great to hear he found his convertible. If you are anywhere near Detroit, the Woodward Dream Cruise is an excellent event to cruise with family. I drove my dad there in the 88 but he has never had anything to bring. This year I hope to have the 90 up and running so that I can surprise him before Woodward. Good luck with the vert.

Thanks Steve for that note, I couldn't remember what it had stated on the Vintage Vehicle Sheets you had shown me at Port Colborne. Therefore according to GM Canada, GM exported 77 Reattas to Canada in 1990, 17 coupes and 60 convertibles.

Steve R had a GM Canada RPO sheet done on his 90 convertible and I believe it was about 60 convertibles in 1990. As for coupes I have the sheet saying 17 coupes were exported to Canada in 1990. Just adding my two cents, comparing the sheets I had the exported number, just forgot to take note though.

Sorry about my late reply, had Christmas holidays get in the way but I had gone to see this car a week and a half ago or so. Thanks for Tom to letting me see the car, great guy to deal with and a car guy himself, however I have two projects already and have to focus on them so I could not pick this up. Anyways I was going to give my best description of the car. This is an early 88 first off, last six digits of VIN being 900413, and the car is a red on burgandy car, order guide said you could not order this factory but Craft Centre was apparently pretty flexible. The dash bezel around the CRT still confuses me with the embossed GCC. Seats are in good shape except for the 16-way control box has come apart from the seat and is missing the control bezel. Seats probably had the suede bolsters but replaced under warranty. Headrests still show suede. Steering wheel would need to be recovered, dried out on top from sitting in sun. Headliner is drooping and the drivers door panel has two minor tears, one near window and one on armrest. Console cover also needs redone and there may be a slight fading in the carpet but not 100%. Also the paint on the car is original, no clearcoat is left on the hood but paint isn't too bad elsewhere on the car, fadng on the roof is maybe one other area. Pinstripes are still on and in good shape. Rust is definitely an issue on the quarters, drivers quarter would best be replaced but could be fixed by a good body shop also, rust on wheel arch, under gas gap where it meets plastic filler and in front of the wheel arch at the lower corner. Passengers has some rust on the wheel well. Trunk lid ls has some rust starting but that is all. Taillight reflector is damaged, easily replaced however the tailight would need replaced.Something hot must have morphed the plastic at one side, not cracked just distorted in one section. Car is missing grille and passengers foglight. Tires are shot and rims best be refinished or replaced. Underneath the Reatta seemed solid, rear frame rails still showed original paint with some rust coming through. Looks like its just rusted as its been sitting on grass but I would guess the car saw maybe one winter, maybe two. As for the electronics, I dont know their condition, battery was dead and hood frozen shut. So I have no indication of mileage, whether headlights work, etc. Anyways that should best describe it. Best part, all glass is good and car does have a fair bit of salvageable parts. Hood is rust free, just missing clearcoat and paint is dried. Thanks and happy new year to all.

The rims are from an 07 and earlier CTS as they share the same bolt pattern. However these are not stok rims, the CTS had them as winters. As for the exhaust tips, they are full custom, single outlet coming out each side of the muffler, splitting into the tips, it is actually four Magnaflow tips fabricated to make dual tips on each side. Yet again, custom so it could be unique to the car.

Forgot the pictures of the dual outlet exhaust that the car has as of early last month. Magnaflow Camaro muffler with dual outlets, 2.5"' stainless exhaust from the manifold back

NCReatta, they are 17" rims, 7 inch deep I believe. I bought all 4 for $150 off of a CTS. Riding on 225/45ZR17s however I might switch up to 235s. My wheels are also spaced an inch an quarter, bolt on Eibach spacers, not the cheap slip on type. They are made by BSA, not sure if they are still made, quite a hard company to find now. I might eventually switch up to BBS RS', crosslaced style with a deeper dish, black with black chrome lip.

Port Colborne Car Show, we had 5 Reattas present at the show, 2 90 verts, 2 90 coupes, and my 88 coupe. Fall Reatta drive through Caledon and Orangeville, Ontario, Canada. Few of us owners, most of us post on this site and we all enjoy the Reatta experience.
