- Wed Sep 21, 2011 4:49 am #273334 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

- Wed Sep 21, 2011 7:59 pm #273468 for 300 to 350 hp you'll need a bigger turbo and injectors.
the 450s should be enough for the m24 though.

- Wed Sep 21, 2011 9:57 pm #273493 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

- Thu Sep 22, 2011 6:11 pm #273735 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.

- Thu Sep 22, 2011 9:32 pm #273775 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.

- Fri Sep 23, 2011 1:21 am #273841 that is a big difference man, r u selling the other? lol jkjk, id like to eventually do a hybrid t3/t4 too

- Fri Sep 23, 2011 1:47 am #273848 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
