Internal vs. External Wastegate?
I am piecing together a turbo kit for my h22. As the title states, i am curious which type of wastegate is better. Personnally i think that the internal wastegate is the best for my turbo future but i am open to other thoughts. My plan is a T3/T4 with an internal wastegate set at 7 psi. Don't want anything more than that and think for the money it is the best way to go. Thanks.

not as of now. With a good tune it will handle it just fine. plus i am a college student and will really only driving the car on the weekends. Another thing I was wondering about is the blowoff valve. What is the best for the lowest price?

well its not the whole thing of howoften your goin to drive it but how the aluminum pistons and cylinder walls can tolerate above normal atmospheric pressures.
from my knowledge... the H series internals dont like boost or spray. ive seen h22 pistons that were boosted at 8psi and they werent pretty...
as far as wastegates go... an external will give u more predictablility about what its goin to do and it will be easier to make more power down the road if you wish to. this is b/c you can always jus go and swap springs out of the hat. as far as internal wastegates go your goin to be more limited to the power production if your going for an upper hp car

first off are u doing any internal mods to keep the all aluminum h22 from melting... traditionally those engines havent responed to boost or spray

That makes no sense whatsoever

thanks remmy, i have never heard of a correctly tuned h22 blowing for 7psi. anyone have any thoughts on my blowoff valve question? What is the best for the absolute best price? are the stock 1gen DSM ones any good? another thing i am always wondering is why all the stupid boost gauges you find go to like 35psi? its stupid, why can't they make them to a realistic 10-15psi. Is it some macho thing to have a 7psi car but have a 35psi gauge?
