well the question was a combo of both. 'ets recap what I want. I have an 86 auto car that will some day be a stick. I am putting in an 87 turbo, ic,and hood. likely to put in the big vam. as stated before and asking the question what is the difference that made the stick car have so much more power. 150 in 86 and 190 in 87. the question was do I need the 87 computer and which one (auto or manual)? from what I have read here in all of this wonderfull information, looks like the auto computer would be the best to go with because of the more aggresive timing and fuel maps. just a little confused on why if the auto had a more aggressive tune, then why did the stick make so much more power.  was it just highr boost? Dont seem to me you will make much more with the IHI. And also, would it be a true statement to say that the TC had no IC before 87?

Autos typically rob the engine of more power in comparision to a 5 speed. Pretty well known fact regardless of type of car. I used to have a 4 speed Fairmont with a I-6 that would dog out a I-6 auto 'mont.

I'll let the experts reply for specifics on the rest.

Yes I do realize the auto uses a great deal mor hp percentage than a manual but I thought we were talking in Crank hp, not rwhp. someone please clarify that for me. My girlfriend drive a 3G eclipse gt auto car and I had a gts five speed. I could pulll three cars on here before getting into third. Hence why I say that I will eventually to the T5 swap. Now. Which computer for my setup Chuck?

To add to the discussion. The '86 has a max boost of 15 psi. If converting a pre 87/88, I recommend the LA3. I swapped it into my '86 along with the large VAM and have a much better running engine and better idle control. No dyno comparison but seems to pull better. I would not do the swap without the larger VAM, you'll run richer with the smaller VAM. As a side benefit, my highway mileage improved a bit on a recent 350 mile drive. Best PC1, 30-31 mpg, with the conversion, 34 MPG. I also wired in IAT, VSS, and BOO.

On the boost issue, save for maybe the 85.5-86TC's (manual), the max boost on the non-IC TC's from the factory was 11#


Other than those, the 83-85 non-IC cars all ran 11# boost, regardless of auto or manual.  The ECU's also could care less what trans was behind the engine until 87.

The '87-'88 5 speed ECU could care less as well, which is why a A4LD won't shift into O/D or lockup with a manual computer(Yes guys, Chuck is fully aware of this) ...

I did install a '89 Stang 2.3 A4LD computer in a '87 5 speed, ran fine, but threw a code cause it couldn't find the lockup solenoid(actually ran noticeably better[smoother], so became a permanent change).. What I did to fool it, was connect a lamp between the lockup signal out on the EEC to a #1895 bulb that was connected to the EEC power source... No more code and the bulb lit when crusing, because the EEC thought it was in lockup...

Well I got all my parts today. should be a fairly easy install. one thing I did not ask before. I know I have to change some water lines but what about the exhaust. Is the distance from the turbo  to the down elbo the same? If I have to mod the exhaust I may as well grab a header. Oh well. Hey my cat has NOSTRILLS! lol

Chuck, I read your statement correctly the first time and added to it.
