ive never really messed with gms so im going out of my comfort zone with a third gen firebird with a 2.8l im not a huge v8 fan (i own an S4 myself) i would like to stay classy with a v6 but im not sure where to start with this one i originally wanted a grand national swap but im finding those few and far between i need a 5 speed and i was reading about a 5 speed in the 5.0 birds but would that bolt up to my 2.8 also iam definatley adding a turbo and was wondering what i was looking forward to as far as an engine build

 

what year 2.8?

u can do a turbo system for around 800 bucks to start , if u want big power u will spend around 1200

can u weld and do ur own fab work?
what condition is the engine in now ?
btw a 5 speed behind a turbo v6 will require an exspensive clutch to take the power even at low boost
cclutch will run around 250-400 bucks depending on how much power u want

 

its a 82 i want to run under 10 psi the engine runs i wouldnt say it runs well but theres no problems it just has a little mileage on it i can weld and all would the stock automatic trans be able to handle it and could i bolt up a 5 speed

 

dont do a turbo system on that car , that has the carbed engine which has crappy small valve heads and small crank journals. those engines are known to break the small cranks even bone stock

wat u would want to do is get a 3.1 or 3.4 engine , and swap in the ecm from a 90-92 car , and then turbocharge that

 

that car doesnt have a the 4 pseed auto does it?
i belive the early cars had 3 speed auto th250c or th300 or something similar those transmissions will not hold up

 

word. thanks

 

Truth

BTW Welcome to the TGO V6 board

 

Welcome to the site and listen to what Porject 89 and fasteddi say-they know their stuff very well. They are right the 82 should have the 3-speed auto in it and it's not very good at all. I take it you have a 82 Sport Coupe? got any pix?

 

If you're looking for a 5-speed get one out of a 3rd or 4th gen V6 car and it should bolt up. Crossmember may be different but you can use one from a 5-speed 3rd gen. I'm not sure if the driveshaft will work from a 3-speed, but any 700r4/4L60E or 5/6-speed 3rd or 4th gen driveshaft should work; best to get an aluminum one since they're usually pretty cheap anyway.

A V8 5-speed is more-or-less the same transmission with IIRC different gearing but you would need a V6 bellhousing anyway because it's different.

I put a 6-speed behind my V6 but it's probably the most expensive transmission option.

 

if u want to do a turbo down the road get a 4 speed auto or swap in a th350
