Thread: 85 Turbo Trans Am

Well i bought my moms 85 trans am gona just fix it up and go from there motor is number one concern right now.

LS swap!!!!!!!!!!!!!!!!!!!!!!

sweet ride man.
im a big fan of thirdgens, as most things are easy to work on and parts are pretty cheap.
supercharged 350...DO IT NOAW

You first need the tpi then supercharge. It will be a beastly motor.

Woohoo another turdgen! Welcome to the family. They are rather easy to work on unless of course you are doing exhaust manifolds on the 350 or spark plugs on them....ask me how I know.

Pft you you nothing of hard to get Spark plugs. try a 454 corvette Plugs with ac takes 4 hrs to change all 8

TPI is way too restrictive.
carb setup is way better on those motors.

Lq4 t56 swap? C'mon guys!!!!!!!!

Then drive my g82 with g90 then talk to me.

buddy has the LQ4 with t56.
heads+cam setup.
that thing is a MONSTER

Took me and my neighbor 4 hours with all the emissions and crap still on the car.

As far as breatheability go shortram or go home, or FIRST injection (or whatever its called) or whatever however I vote LSX with the T-56. But yes these things supercharged (or even turbo) will run hard! There is a guy running 9's in twin turbo 406? cubic inch camaro on thirdgen.org.

ill get more pics of the interior tomorrow i go pick it up tomorrow it has a 305 with a blown bottom end. It was ran to low on oil and pretty sure spun out a few bearings. Before it was parked step mom paid to have all new performance heads put on edelbrock performance manifold edelbrock v/c and edelbrock carb with a round edelbrock air filter car has sat for 3 years some one stole the air filter and carb and left a quadrajet in the back seat it also had performance spark plug wires some one stole too

im going to buy a 350 long block and switch over the heads manifold v/c water pump alternator pulleys everything i can and rebuild the guadra junk for now untill i can get an edelbrock going to have to save the money first for the engine looking at about 1500

ive thought of going over to an ls1 but that would be to costly to switch everything over to electronic

id pop a 400 or stroked 350 in it. will cost about the same in the end. you got the top 1/2 already.

ditch that quadrabog, they suck. 650 holly would be nice.

im going to stick with the rest of everything else and do an edelbrock carb but there like 450

this.....too much carb can ruin it, a 650 would be perfect!

we had a holly 750 doubleflusher (lol i called it) on our nova and it ran like crap, then threw on an edelbrock 650 and runs like a champ!!!!!

What would be electronic? You can slap a carb on anything. Hell a 5.3 would be money sauce.

My buddy has an 88 T/A 5 spd with the 5.0 in this color, Its got potential good luck with it!
