All,

Got back last night to Stuttgart from Ramstein where I had been at a conference. A 2+ hour drive at higher speeds on the autobahn (to avoid getting run over by everything from Beemers to delivery trucks) was a definite strain on the engine. By the time I got back to the garage under my apartment building, the "Check engine light" was on (Codes 44 and 45) and she sounded tired.

Beyond dealing with the problems already indicated, I would like to wring more power from the engine. I know some people have gotten some enhancement from the SMEC upgrade but I was wondering if it is really that noticeable.

If the upgrade is not enough, what would be the next step? Is there something else that can be done to the 8v engine to give it more hp without risking a drastically lowered life span (on an engine that may be starting to show its age)?

Thoughts?

44 Fused J-2 (No CEL) Ignition On J2 not present to logic module in SMEC
45 Overboost Monitor Engine Running MAP sensor signal exceeds a predetermined amount of boost.

My first thought is the Hep in the distributor. They fail under heat or just the worst times. It's recommended to carry a spare.....Maybe that's why the screwdriver is in the tool kit? If it runs good today when you start it, that's a failing hep indication.
As for the J2, that gives me shivers since I had a bad splice in another car on that wire.
Turbo-mopar.com has someone else in Germany that has boosted his car.

Correction. There are two members in Austria.

I have replaced the smec on my 89, now the turbo kicks in at 2500 rpm, not 3500. Have heard of great power increases going with larger exhaust pipes like to 2.5" I believe. Turbos like to breath. Can add better breathing heads, add more boost, larger turbo. These increase low end power I know. If its top end the 5 sp tranny seems to be 15 to 20 mph more. I would love my maser to do 185, but even the tc 5's don't go that fast. How much do you want to spend? Be sure and let that turbo cool down for a few minutes, replaced those fuel lines by the turbo? You'll get lots of fast help here.

The T-2 8 valve engine has a lot to offer in the arena of performance modifications. I just punched mine 30 over and decked the block a bit and shaved the head. I also ported and polished the head. Larger valves were installed with a triple angle seat and back cut. I also went to a larger 460 lift crane cam and offset the advance by two degrees. I also changed the smec and put larger fuel injectors in the engine. Now of course you can not do all of that without replacing and increasing the exhaust diameter and going completely through the transmission to make sure it will hold it. I made power gains from the stock 165hp to now making 300hp. Most of everything I ordered was available from mopar performance and fwd performance. Have fun ! By the way, I have a great friend that lives in Stuttgart. I just thought that I would share that with you.

question for you yellowdog. How does the car handle above 80 mph. thats probably the on ramp speed there!!!!

Wild Bill you are so right. I punched it up to 95 and a late model Audi blew by me as if I was standing still. I have ridden with other people with late model Beemers who sail along at 110 fairly effortlessly and yet still have to make room for the Porsches.

The danger on the autobahn is not the high speeds per se, it is that there is such a wide span between the Jet pack supercars, and the family towing their camper cruising along at a stately 65 miles an hour. If that wasn't bad enough, some drivers, secure in the knowledge that the car coming up from behind is always at fault, will suddenly invade your lane when you are practically even with them.

As far as driving at the higher speed, I have not noticed any lifting or lightness in the front. My main concern is what the high revving is doing to the 20-year old seals and gaskets.

I am willing to put some money into the car so some rebuilding is OK. My preference is to get all the parts as needed from the States so that the local mechanics just have to bolt them on. Right now I have used a Chrysler dealership for some mechanical issues but I think I will want to find a specialist soon.

One idea I have batted around today is whether to have an engine modified as has been suggested and then have it shipped over and just dropped in.

I like the sound of your mods but was wondering how much increase the tranny can take before you need to modify it? 200? 250?

WARNING! NEOPHYTE QUESTIONS TO FOLLOW.

One thing I wanted to ask about before I head home tonight is whether anyone has replaced their 8v engine with the 16v one while keeping the auto tranny?

If I had a complete DOHC Maserati engine available and an upgraded SMEC programmed for the 16v, what would need to be changed to the rest of the car during the bolt on process? What issues or problems might there be? What would be incompatable?

[Bill Reichert]

The transmission won't take 8 valve mods very well unless modified. With mods it will take 400 hp.
