SR loosing power when floored... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Omega47 · 03-20-2006, 04:23 AM

I would have searched if i knew what to call this problem. Searched for hesitation,boost etc,no luck...
Heres the info on the setup.
S13: SR20DET Redtop.
stock evertything besides:
Front Mount
Type S BOV
Straight Pipe 3'' to Megan Catback Exhaust.
HKS Mushroom filter.
Manual Boost Controller.
Car is at around 9-10 psi,not much eh?
Well,was all good till yesterday,was driving and got on it on the freeway,when i floored it got a sec of pull then it feels like the car just looses power,boost gauges hits 10 then down to 9,but stays there when it looses power,boostdoes not change,My question is what are some things to check,maybe some suggestions by people who have had this issue before.

Any help is greatly appreciated.

timing, check for ecu codes, boost leak.

How old is your clutch? When I got my sr20 in the clutch was ok but after about 300 miles it would slip hardcore when I tried to floor it. That might be a problem. New clutch and my car was 10000X better.

That would make sense,hmm ill check it out. Any other ideas,seriously considering the clutch it slipepd a bit when i first got it,that would make the most sense.

Check the ECU for codes first, because it is fast and easy. Maybe your knock sensor, or some other sensor, died.

K dumb question which one is the engine light,i checked for codes in the past never saw a lgiht come on,plus i disconnected the tps and o2 different times for different reasons and never saw a light on the dash,so which one is it,maybe its dead.
