The Sr20/Sr22vet thread

Hello guys, it seems a lot of us have similar setups.

Mine is as follows:
CP 9:1 pistons
eagle rods
N1 Cams
supertech springs
EFR 7163 T4 Twin with 4 port ebcs and twin port actuator
3.5" exhaust

Been to the dyno recently and I'm kind of underwhelmed with the results.

Horsepower aint that bad for 18 psi. However the shape of the curve is what I dislike the most.

A friend of mine with a very similar setup has a graph that looks exactly the same as mine.

Mid range is great, however, I felt it lacked the top end it used to have when it was N/A.


Is the 7163 choking up top or what?

Same engine just different pistons and turbo setup.
Dotted line is N/A.

That?s pretty low power even at 18psi. My GTX3076R made almost 500 on 19-20psi.

Are your cams switching over? It doesn?t seem overly apparent on the graph.

Yeah I know its kinda low for the turbo and motor combo. My buddies stock SR20DET with a 6258 did 10whp less on the same boost.

VVL are turning on at 5500 rpm.

Why so late on the switch over? I engaged mine at 4400.
