This thread...

Makes me...

Nvmd, lost my thought.

My car is red.

So does that mean I can just throw a semi turbo on my car an hope an pray nothing goes boom? Sub'd this will be a fun project but well see how that gt holds up

The only thing holding you back is your $1,000 budget.

The trans you would need is going to run you $5,000. I know this because I priced one for my build, and that's when I decided to demod.

As far as the turbo itself, I wouldn't use a semi-turbo. I would use an ebay knock off of a name brand turbo. As far as the turbo crossover, with a welder and some pipe it wouldn't be too hard to fab something up. Plan ahead, space will be limited.

After you spend money getting your hotside setup, you'll need a boost controller that keeps you from going over 6 psi, and a tune for boost. Get HPT and do it yourself. That should all get you over your budget but by less than $500.








In all reality, if you can't afford a new engine and trans, you should leave this idea alone.

wastegate/bov/intercooler/install kit will run you about $300 on ebay prices.
A wideband is a good idea, not needed.
I ran a bone stock trans in a lighter car running really low 11s, so you really dont need a trans if you are not a stupid asshole that doesnt know how to drive a car making power.
Tuning is cheap, and you dont really need to even tune anything if you keep the whp under 375 (17psi) and run on a stock LT1 maf.

ghetto turbo kits have been done often, on stock transmissions... they work fine and are really easy to do.

Bull**** on the $200 for injectors and a fuel pump. I'm calling you out on that. There's no way in hell you will find that new at that cost. Post the links to these. Your trans comment again bull****. Why because its not going in a Fiero its going in a piggy and I don't give a **** how it drives it the trans is going to go out. People have GTP's with stock trans go out all the time and they don't make near enough power a turbo will. How in the hell do you think that he won't eventually need a built one or a replacement is bull****.

A seasoned owner with a lot of spare parts and the right resources could do this for potentially under $1,000 but you have to be more realistic.

Hx52 cuz you all suck teh diks

im new to the GP world from the truck world. i know many people with modded LS swapped trucks and stock 4L60E trans that handle 350-400 wheel HP. i would assume a 4T65E or 4T65E HD would be able to handle quite a bit. then again this is Longitudinal trans vs Transverse trans, so there may be some other weak links..

Lol... You have a lot to learn

fun article on the 4L65 that kinda describes the torque rating of the trans. Again for a longitudinal trans soo..FWIW

Yeah, these transmissions seriously suck. It will never compare.

Power and FWD don't mix....






Is it clear yet?

i can see where traction can be a reall killer..

Lol traction don't happen
