What are some good know brands for h23 internals for boost

[92preludeSi]

bump i need to know some parts

[Brash22]

Have you thought about searching around? There's enough info on boosting H23s on here.

[ogsmakdade]

crower, skunk2, carrillo, ferrea, golden eagle, je, wiesco. what parts are you looking for?


if you want specific brands for each part, specify the specs of your build and I'm sure you'll get the answers you need

[92preludeSi]

maybe about 20-25 psi

[PreludeS]

/\ damn thats a bunch of boost...

[92preludeSi]

gonna spend quite a bit of money on this project over the coarse of ayear

[Si Speed]

talk to lilbluelude. He's in Cumming and running 29 psi I think. I don't even want to know how much he's spent on just the engine.

[92preludeSi]

on an h23?

[PreludeS]

no he runs an H22, which would make it more expencive probably lol... good luck thow.. and I thought my goal of 13-15 psi was high lol

[92preludeSi]

20-25 is what im wanting after i build the engine

[PreludeS]

... what turbo you plannin on runnin?

[92preludeSi]

not sure im set on building the engine first and then ill get to piece the turbie kit up

[PreludeS]

well one thing to consider... correct me if im wrong but from what I've read and heard.... when you run a big turbo it takes longer to spool up than a smaller turbo meaning more turbo lag... so Id look for something small that can push that much boost

[92preludeSi]

i think ima go with a medium size turbie

[PreludeS]

thats probably smart... in order to turbo the H23.... you will first need to have it sleeved... that will be like a grand

[92preludeSi]

yup i think it will be quite a bit, but my dad does alot of buisness with this little engine shop down the road. so labor should no be that bad

[PreludeS]

ya gotta have a good machine shop

[92preludeSi]

ohh yeh they are real good

Smaller turbo's can't flow the same amount of air that big turbo's can, and airflow is what = power, NOT psi!! Once you start turning the boost up on smaller turbo's (like 14b's and 16g's on our motors) beyond their efficiencies, they start creating tremendous amounts of heat, and heat-soak is a major loss in power, and hot air can easily cause detonation, which means engine go boom.
Small turbo's are good for no turbo lag, but in the upper RPM's they run out of breathe, and just blow hot air.

Larger turbo's are more efficient because they don't create nearly as much heat as smaller turbo's because they are able to flow much more air and they also stay within their efficiency ranges. There is ALWAYSS a compromise to make when modifying your car. Here, its whether you want no turbo lag but you sacrifice not making alotta power, or you have some lag, but make much more power.
