  1. That would be interesting if any information could be tracked down. I have looked at as much information on the factory cars as I could find and the fwd turbo iterations appear fairly similar to what I have done but with the older 3.8fwd engine. The hi-boost rwd looks to be an old style GN engine and drivetrain. There have been different people that have done turbocharging to various fwd GM cars but no kits I could ever find.
  2. I would give that a qualified yes. There have been a few that have done supercharged and manual transaxle swaps, Daniel being the most recent and modern. No one has done much with the turbocharger aside from the factory prototypes 30ish years ago. I do it as a mental and curiosity exercise. The ecm is really pretty flexible and can accommodate many changes but I am just feeling my way through and it's almost time to put the car away :(( From a purely power potential, turbocharging has more potential, so it must be used with a fair amount of restraint unless a whole host of other things are upgraded.

    Minor issues after engine work

    I haven't tested a regulator in that way with fuel but I have applied air pressure and it did not leak air until near the set point in the low 40#'s. It will be interesting to see if replacing the regulator helps. I am experiencing similar issues, nothing from the injectors, no fuel in vacuum line, replaced regulator and problem persists. I don't really want to drop the tank but looking like it. Oh yeah, fuel pressure is normal and responds normally to vacuum, but extended cranking at irregular intervals.

    Sticking Calipers - Brake Pump?

    Look closely at the front brake hoses. It is not uncommon for the inside of the hose to collapse and prevent return fluid flow. I didn't have problems with non-release of the brakes but I was surprised at the poor condition of the hoses, particularly where they twist and flex, when I did some unrelated work under the front end.

    I know this is getting a bit off topic but loosely related. I would be interested in the story behind the OBD1 tuning guys still available today. I would be grateful to hear how this was done. On a related item; I have been considering an emulator from Moates as a means of speeding up the tuning process and would value your thoughts if it would be a good investment. TIA

    Here is a quick pic of the Memcal w/zif scket and chip installed. Please note this is a replacement ECM I purchased that came with the ATYK Memcal where my original is ANWU. I use the spare ECM to power test MAF's on the flowbench also. There may be lower profile zif's available? This one has a lever on the end to completely release the chip for removal.

    Thanks for jumping in As I mentioned, Ryan at Sinister/GMTuners did the zif socket for me, but while it works great for easy chip replacement, the programable part, It is too tall to let the ECM fit back into the stock location. Mine just lays on the floor while I work on the tuning aspects. If the 256k chip won't take programming, it could be replaced with a new blank replacement. I think one of Moates emulators should connect to the zif socket too to perhaps speed up tuning process?

    Sticking Calipers - Brake Pump?

    The statement that there is something wrong with the brake pump is pretty vague. Does the pump run? If the pump runs, how much does the fluid drop in the reservoir when the accumulator charges? In other words, have you tried the tutorial on doing the brake test?

    Did you know?

    I have no way to monitor the total traffic group this site, but there is no doubt there is some erosion. I was concerned when I learned of the Facebook group and expressed misgivings at that time. It would be helpful if it pointed people to this forum but I fear the reverse is true. Generally I agree with the thoughts expressed here, and have the same concerns, but it's preaching to the choir. It's unfortunately similar to having a single source for news/information, talking to the same people, visiting the same places, or none at all, and generally not looking at the world from more than one perspective. I certainly post less, although I visit often. I see little interest in what I enjoy as a pastime, so don't bother to post much. In that respect, Ronnie's old site was more geared to the hands on and not just to preservation. I hope you keep trying.

    I can't seem to get anything else to work, nor can I post a .pdf, so I suggest going to the TunerCat site: http://tunercat.com/ On the left side, scroll down to the "ECM Definition Files", click on that. When the files come up, scroll down to the Buick/Olds/Pontiac cars and $5B2 definition file. Click on the Info button on the right side. This is the list of what is contained on the 256k chip embedded in the Memcal. Many, but not all, parameters can be modified. Hope this helps. It's all free open source information. Too bad the BCM isn't the same😐

    The small chip is the only part of the larger Memcal/EEPROM that does get reprogrammed. I don't know all the details of what resides on the rest of the assembly but I know some of it is the base operating systems such as the limp home mode and open loop operation. I do not know for certain if knock processing is all done on the small chip, just that there are parameters that can be adjusted that affect it, but usually that is left alone as the factory settings work well. I am not versed well enough in this field to know all the details. I will see if I can find any better info. to illustrate what I mean.

    I am guessing the "other chip" referred to is the conventional 256k chip embedded in the larger circuit board inside the blue housing? Hopefully Padgett can better define this, but the reprogrammable part is indeed the smaller chip. I do not think the small chip does any of the storage, at least I have never found it. It is primarily the instructions on what to do with information that comes into the ECM. I know the attack and recovery instructions for knock are contained on the small chip, but I do not know if wiping and reprogramming the chip will fix a problem or not? As Padgett suggested, contacting Ryan at Sinister Performance/GM Tuners may be able to help. He has been very helpful to me in the past. My first "performance" Memcals were done by Ed Wright at Superchips, and later Ryan helped me extensively with reprogramming for my original turbocharging experiments. He did several chips for me, and finally modified a Memcal to hold a ZIF socket in place of the 256k chip so cheap and readily available chips could be programmed and easily changed.

    Oil Pressure

    Agree with all of that. I shim my relief spring a bit as I use an aftermarket oil cooler.

    Oil Pressure

    That sounds similar to mine except the dash gauge goes to about 3/4 cold when above idle. Is it possible the oil sender is incorrect? I seem to remember a different calibration from year to year but it may be a false memory.

    Desired Oil Specifications

    I have changed my thinking on the oil viscosity and brand names. I used to use higher viscosity oils than recommended as the increased oil pressure made me feel I was being extra caring for my engine. For an engine used regularly and brought up to full temperature on most occasions, almost any good quality oil should be fine. I am down to three vehicles and a single driver so oil gets changed once a year, and use full synthetic 0w-xx motor oils. If you think about it, clearances are at a minimum with a cold engine and a very light viscosity rating will flow the best and at higher temperatures the upper temperature rating should be at least as high as originally specified. Bearing clearances on the Buick V6 are very tight, it has a crank driven gerotor oil pump plus roller lifters, so no need for excess viscosity. What I find interesting is 0w-40 motor oil, (popular for European engines), is easier to find than 0w-30. JMHO
