Right now Most of the 301 parts I have are stock. I am in the process of adding a 200 4R to my car and it has 3.70 rear axle. Currently the car has a SBC with a 278 Energizer Cam Dynamic Cam with aluminum Corvette Heads and Performer Intake. I want to go back to the Pontiac Engine but don't want...

Thanks for your replies, You are correct, I have a 301 Turbo Trans Am. I want better performance for my T/A. and I am on a hunt for more information. I am trying to put together parts that I would need to make this combination work. Unfortunately Pontiac didn't have the sense to continue...

Thanks for the reply. I didn't know they keep the A/R that common through all those years. I thought the changed the A/R ratios more often. Like I said new to this. That kind of makes sense with what I read "Quicker spool/Less Lag". Has anyone measure the back pressure before the turbine...

Hello Is there a chart somewhere that has all the 231 turbo specifications and model numbers by model year. Have a good day Lee

Hello, you have my attention!! Do you have pictures of the 86/87 turbine housing on your 301T. Also what it the A/R ratio on the 86/87 Turbine Housing. What about the 84/85 turbine housing? why did you use the 86/87. By the way who is Reed? Thanks in advance.

Hello I just read this on the "Before Black" web site. "1982 - First year for the 0.63 Turbine housing. Quicker spool/Less Lag." . I was wondering what the A/R ratio was for the 1979 to 1981 turbos. On another note, is there any way of getting different Turbine Housing with different A/R...

Hello Thank you for the reply, actually that is my back up plan. The correct one according to the site I used is 11 and 30 and the next closest is 10 and 27. Lee

Hello I require a 11 teeth speedo driven gear for a 200 4R. I need this because my 3:70 rear axle and my tire size. I know it comes on buick turbo regals but I am not sure what else. I think it is orange in colour but I have seen 13 teeth gear that are orange too. If it is from I turbo regal and...

Which CK servo did you buy? I noticed they have a couple different ones. Thanks for the input. Lee

Well I was told it was rebuilt at some time, and judging from the whole case being painted black, I think this is true. The person that sold it to me said it was working good and he took it out of his MCSS. I did see the MCSS in his yard. He said he took it out because he is doing a LS swap. It...

TexasT Thanks for the number on the servo. I have been cleaning up the trans and it has the number you said on the servo. I also has the speedo gear ratio that I read comes with a MCSS. I hope the rest is correct too. So far I am thinking of replacing the TC oil pump front seal and also the tail...

I have a canadian 1981 Nascar Pace Car Turbo Trans Am.

Well, when I built my SBC engine a while back, my horsepower target was 375 and I had a turbo 350 trans and 3.70 rear gear. I originally wanted to go 700R4 for the steep first gear and the overdrive. Now I am thinking of going back to the turbo 301 turbo and I feel the 200 4R would be a better...

Thanks for the Relpies. It was said that some of the information was DATED. Is there a place for better info?

Hello I just purchased a 200-4R out of a 86 Monte SS, but I don't think it is the original transmission. Anyway I recall coming to this site and there was a post with 200-4R recomendation, Upgade and tips. I thought this would have been in the Sticky section but I didn't find anything. I tried...
