Replacing the baby Turbos..

[ieatsushi69]

So my stock VR4-1991 needs new turbos..
Can anyone give me a list of good turbos? Or maybe a chart or specs so on?
I googled for a chart and specs but I guess I suck at using google...
Idk how much a stock engine can handle in PSI.. so if I could get some knowledge on how much the stock engine can handle or whats best , turbo for stock engine I'd appreciate this very much thank you.

Stock can handle about 14 psi, but that depends on the car. You need to run a data logger with it to make sure you aren't knocking.

If you don't want to upgrade a bunch of stuff (injectors, tuner, pump, wideband) then I would just get your stockers rebuilt. The turbos will not be your limiting factor with the stock fuel system.

This may help you a little.

So here are 3 turbos I'm interested in. Now I think my stock engine will need some work to handle these. What exactly is needed to keep a hole blown in the block..
Thank you once again.

First decide what your goals are...hp, fuel, street, track, drag, $$$$, etc. Then search. Nearly every turbo, build combination available has been discussed.

You have given no information that can answer your question properly.

Decide on goals, how much you have to spend, and research. If you still have questions, post specific questions and you will be rewarded with specific answers.

BTW, your cast crank on the stock 91-92 engine will be the limiting factor on engine. Most say 400awhp is practical limit.

Well I am aiming for 30psi max no need to be higher.
Street Def, Drag maybe been thinking more and more about it.
Money not a problem.
Hp- 600ish-800ish area.

I did do research on the 19T and they are nice fer sure.
I'm just wondering how much a stock engine can hold Don't wanna put a turbo that is to much for the engine and kill it... That's the main question.
Q- How much can my 93 vr4 engine take exactly. Or quick modes to make it take more. "Take-meaning PSI beating on the engine"


Now can I get a serious answer...

600-800awhp. Get a stage 3 shortblock with a forged crank from Pampena and a Dynamic Racing Turbo kit. DR800-1000. Bolt on DR750s will get you 6-650. Heads/Cams are optional. Clutch is requirement. Fuel upgrades will depend on what fuel you want to run (pump +meth, race gas or E85). Piggy back to AEM, take your pick.

Ninja Performance has great prices on all the accessories...clutch, gauges, fuel pumps, spark plugs, etc.

You can call up Pampena and they'll set you straight.

Plan on $10k+ just in parts depending how much power you really want (6-800 is a pretty big range and requires different parts and support), plus labor.

Thank you for the advice :]

[eengler2]

500ish awhp can be had for much less $. DR650's, a piggy back, fuel pump, injectors, clutch and a splash of race has or e85 and you are good to go on the 93 engine.

You're in NM. Go talk to Matt and he'll get you setup with a turn key build for whatever you want. It won't be cheap but it'll be worth it. For probably $6-7k parts and labor he'll get you a 500AWHP iirc last he said. From there it goes on up. I'd recommend a different motor also.
