I am running a b20 vtec that is mildly built with low compression pistons, eagle h beam rods, race beariings, and arp head studs. I have a Garrett m24 ar 42 turbo running 10psi. I have RC 450cc injectors and an 11lb flywheel. My question is this, with the small turbo I have is it ok to run the 450's and get a good tune (since the motor was tuned for a larger turbo that went bad), or should I upgrade to 750cc before I get it tuned? I am wanting to achieve at least 300 to 350 whp on about 15psi daily, are these numbers possible with my current setup? thanks in advance guys

for 300 to 350 hp you'll need a bigger turbo and injectors.
the 450s should be enough for the m24 though.

thanks for the insight, im wanting to go with a 60 trim garrett which is what was originally on the car when my buddy bought it. The original tune used the RC 450's and the Garrett super 60, was this not a good combination? juss wondering cuz i dont wanna buy bigger injectors if they are not needed

a t3 super 60 is good for 250hp according to the vendors that sell them.
(actually the Super 60 is a turbonetics, Garretts are plain ole 60 trim)
a t3t4 50 trim garrett or larger should put you in the ballpark.

ok cool, I am working on a deal with a guy from a local forum that has an xs power 50 trim, should it be better than the m24 I have now? and if so, is XS Power a good brand?

just so you can see, here are two 50 trims.
on the left, a t3/t4 and the right is a t3 50 trim.
obviously, the compressor housing on the t3/t4 is larger.
it has a t4 compressor mated to a t3 turbine.
both turbos have the same turbine, t3 AR .48
i will be using the turbonetics to get the 300 to 350 hp from my d15b.

that is a big difference man, r u selling the other? lol jkjk, id like to eventually do a hybrid t3/t4 too

at the very least, it will take a t3/t4 to get you to your hp goal.
a straight t3 will not get you much past 250 hp.
and you should probably look into gettin a walbro 255 fuel pump.
if a 15 yro stock fuel pump cuts out for a second, a b00sted motor is toast.

I forgot to mention that I am running a 255, my bad, in all reality I am not concerned with hp numbers exactly, I just want a fun DD, I eventually wanna run a Garrett 50 trim though since that was originally on my motor, thanks again
