I just installed these on my s14 SR. Yes not much info about people running them.

I got the Tomei USA 258 set for s14/s15 SR.

Some info for me, S15 turbo. Still stock ECU, Stock 370cc injectors and have the basic bolt ons, exhaust manifold, elbow, downpipe, exhaust etc. 10psi

I'm still driving it easy to break in.

So far a little loss of torque in low end but it kicks in pretty good on mid range. I haven't redlined yet, going to drive it a bit more before I do but I can tell the power comes on strong. Idle is pretty stable, a little lumpy and rough but that is to be expected on a step 1 cam.

Only question I have that I haven't found answers to... On cold start, my SR hesitates a bit in the revs. Once it warms up it seems fine. I know I'm still on stock ecu. Anyone else experience this on cold start?

Don?t have any vacuum numbers but nothing seemed out of the ordinary other than a more lumpy/rough idle.
