cam differences (turbo vs. NA)

Post by mcbrat »

so, how would the cam differences between turbo and non affect engine run/performance.... more specifically I suppose, is how (if at all) would the cam angle sensor and it's signal be affected....

granted, it could just be the ECU, because the engine is all "wrong" .
but I still have a "spot" where the engine gets a bit funky, and I either gotta give it more gas, or let off totally.... then I can go again.

If I'm smoother on the throttle, it seems to do better than if I stomp it down...

For reference, franken engine consists of:
ej25 (NA) block
ej25 DOHC heads ('96 with HLAs)
ej25 flat top pistons
ej22t crank/rods
ej20g intake manifold, 440 injectors, vf8 turbo
WRX tmic w/TurboXS bypass valve
very short intake with cone filter.
ej22t ECU

I don't think the cams should play a huge role in your problem.

Do you have a wideband sensor, so you can check your AFR's?
