That's normal.

 

Most engines will use a hydraulic 'lifter' to take up tolerance in the valvetrain, thus reducing noise. The 9000 RPM dictates otherwise for this engine, generally hydraulic lifters begin to fail around 7-8000rpm. I personally wouldnt say this engine has lifters but rather solid 'tappets' that need adjustment once in awhile depending on how much you thrash the engine.

Note: A Subaru 1.8 liter turbo flywheel weighs in at 22 lbs.


Johev, my Idle was like that too, but being modified might have other factors. I re-adjusted my TPS but that was further modifying the car, which some people around here will, well, bite your head off for. . .

Actually I would not describe the 14 lb. stock flywheel as

 

good god. I was scared mine was the only one that did the whole 600 rpm thing every now and then. I feel better now. thanx

 

how easy was it to adjust your tps?

I have toyed with mugens ECU and it runs rich, maybe because I have a bored TB, but didn't know how or if to adjust the tps...any help would be appreciated as I am running stock ECU for now and probably may stay there.

I've noticed that with my AC off, the engine doesn't bog when coming off of the throttle.
AC on and I get the problem described above.
