No power at top end with SR? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

hey i have a problem with my SR. Im just not feelin it at the top end near red line. It will boost up fine in mid range because i can feel it pull hard but once its at full boost past 4-5k RPM, i just dont feel it pull anymore. The first thing that comes to mind is boost leak correct? Well, it just dosnt feel like a boost leak. If there was a boost leak, u'd feel it just suddenly cut off. With mine the power just goes away. I've also observed my boost guage carfully as well, it dosnt fall bakc down after hitting full boost like if it would with a boost leak. I've done compression test numerous times as well. 160psi for all 4 clyinders. Problem with the turbo maybe? Im stumped.

How much boost are you runningand on what turbo?

Silverbullet · 11-15-2004, 08:45 PM

just the T25. Really? Honestly it feels like theres no power at all at top end.

sounds like your running more than your turbo wants to give

i dont no bout that, t25 comment but mine pulls hard all the way to redline, then again i baby the hell out of it i got on it that hard only once and it felt good, so i dunno try not to beat on it too much dont want ur turbo to go if it is something up with that. good luck.

Like you said...could be a boost leak. Done a pressure check on your pipings yet? Just because it doesnt fall on your gauge doesnt mean your not leaking.
