motor B18c1. bored .20 over JE pistons/rings 9-1 compression Eagle rods. rocket valve springs and retainers, cometic head gasket, autotechnic block guard, ARP headstuds, ALC bearrings rod and main, polished gsr crank A.E.B.S. intake manifold, CTR cam-exhaust side, aem fuel rail, precision 880cc injectors, walboro 225 fuel pump, aeromotive fuel pressure regulator (currently set to 40) ss autochrome tubular exhaust manifold, turbonetics-garret hybrid t3/t4 turbo tial 38mm wastegate, 2.5 inch down pipe 2.25 inch exhaust-no cat with a 2.25 to 3.5 top speed muffler, greddy intercooler (rather small piping) turbo-xs blow off valve. tuned with a hondata s200 running 15psi. I dynoed at 308whp and 206 torque at 9,000rpm.

everyone thinks I should have more hp. comments?

 

which t3/t4 turbo? there are a LOT of combinations with that name. that's a lot of guessing here.

 

turbonetics\garret I don't know what trim size.

 

You don't know what size turbo you have?

 

probably a t25 or something

 

The exhaust sizing and continuous mismatch will cause some of the power loss you're speaking of. You seem a big down on power despite this.

Answer these questions:

How big is the charge pipe, exactly? Measure it pls kthx.

Does the manifold have hairline cracks? It could be leaking under power which will attenuate power.

Where does the turbo spool up/make it's first psi of boost?

 

even if its a 50 trim its low on power, but you have a lot of restrictions, small charge piping, dinky 2.25" exhaust, ss auto mani. the CTR exhaust cam doesnt help nearly as much as a CTR intake cam.

with a few changes here and there im sure u could pick up a bit more power.

like shodan said though there are so many combinations of t3/t04 that its tough to give you accurate advice.
