I looked into this for 3.8 period, would like in my old gen 1 H body LeSabre. there are alot of things I'd like to do though
. Anyhow as Im sure most of you know its been done to 3.8 Fieros, thats where I got my information but I dont visit the Fiero sites. I guess theres two ways to go about the flywheel, one is machine a 3.1 to bolt to a 3.8 or machine a RWD Camaro 3.8 to work for a Getrag.
After that your golden until you need to do proper lenght drivshafts.
Then figure out how to make engine run proper with out auto hooked up to the computor
I looked into this at one time I was considering a TGP that needed trans anyhow. Knowing that gen 1 W bodys came with a Getrag I figured maybe swap one in a TGP. Very few of those TGP guys had at that time successfully done the transplant. At that time 2 yrs. ago no one had figured how to get engine to run proper without the ECM getting the info from the auto tranny. Certainly much has been gained in the knowledge department in the last few years. Obviously some Fiero guys must have a handle on the control module.
***TGP for those that dont know was a turbo 3.1 V6 Grand Prix made in 89/90 came only with the auto***
Theres a * 1 L67 Getrag Reatta just recently getting done.
When I asked the TGP guys if I could put a tranny from a V6 Beretta or Cavilier into TGP - They said it would be way easier to get W body donor and go dirrect. Because of half shafts, and some inner shaft in tranny is different. Cant think of what its called.
Now youve done all the research, spent all the money on used tired Getrag to find out you had to rebuild (I've heard #'* around 2500) , done all the fabrication, got er in there and rev your 340 ft.lp L67 up and let the clutch fly and WAM
GRENADE your little Getrag clear out the back door of the garage.
I still want to try it though.
