t4 turbo on 91 laser

[NemesisSPL]

I am new to how the turbos work.....Can someone tell me if a T4 turbo will fit my dsm....i have a someone selling me one but i dont know to much about them..It would great is someone could tell me if this will work....My car is non-turbo now..So i dont know...anything will help a bunch...When i signed up i must have screwed up and put turbo on accident on the sign up page

With a nonturbo car, this is a "hell, hell, hell no". Even with a turbo car, in stock form like yourself, the answer is a resounding "hell no".

"Fit" and "work well" are sometime mutually exclusive. DO NOT buy a T4 turbo for your Laser. You hear about these guys putting down 500-600 HP with DSM's? The turbo you speak of is larger than the turbo most of them are using.

Tell your "someone" thanks, but no thanks. You will have to have a TON of mods before you could even START to take advantage of a turbo that large. Start with the tuning guide on this site and start at the beginning.

If you really want to make crazy power, sell your NT and buy a turbo car or get one of the "kits" available from Hahn, Star or others. It will be a lot less money in the long run and a lot more fun!

Yeah true.....But i thought it was a hell of a buy for 350 bucks shipped to my doorstep....I dont know what to do at all...I dont know how to even hook up a turbo but have close friends that are turbo experts but havent had a chance to talk to them since thisguy gave me the offer

my opinion before you buy a turbo at all, or even think about it is learn everything you can about turbos first, it doesnt matter what your friends know, or think they know, when it comes right down to it, your going to be the one with a turbo, so you need to learn how to take care of one, you need to learn the theory of how they work, etc, etc, but a t4 is way too big anyway, your car couldnt handle more than 7 psi anyway without blowing the piston rings or maybe the pistons themselves, to do a turbo on a NT car you really need to put in forged pistons, injectors, etc etc, turbo systems are complex, and if your serious about putting one on your car you need to read up on it

give one of the stickies in the nt-turbo forum a read through to prepare yourself for what you're getting into. and due to the complexity start with something small and cheap like a 14b then move on.

but as they said this turbo is a monster and in no way is your car now or probably ever going to be able to handle it.

Does anyone else see that he is a turbo car already, or is it just me?

BTW, just so you know, I personally run a T4, it's ball bearing, e-trim 60-1 and that helps with the spool a ton. Granted the turbo is big, but others use it too, such as the ETE32, ETE52, ETA32, etc......so yes it is a good turbo, but it does require supporting mods as well. I'd put it on, I love mine!

No, he is non-turbo.

The ETE turbos you mentioned all use T3 turbine sections with T4 compressor sections (T3/T4 hybrids)--not a true T4 turbo like what NemeisSPL is talking about. Going to a T4 exhaust housing and wheel is going to slow the spoolup considerably.

Before giving a T4 a try you need to learn about air/fuel mixtures, internal capabilities, turbo cfm capabilities, and what it takes to maintain a turbocharger. You can't strap that turbo on your car and move from there man, it will take some time learning, and hard time on formulas. To have that turbo on a NT block would mean internals would need to be forged. That turbo puts out a lot of CFM, and more likely you would need to raise your RPM limit so therefore you could spool up late and still have rpm to keep going. Stay in the T3/T4 or T3 range, or even smaller. I am only going to use a T3 60 trim, and it pushes a lot of CFM already. You can just imagine what a T4 would do.
