Notch Top Problems Rich and No turbo - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Okay so I just put my S14 WC notch top sr20det in and had it driving but it was fluttering the first two days, even though I have BOV installed, BOV must have not been lined right off the vacuum. I don't believe my wastegate was stopping at its 7psi or whatever is stock I believe from a line put in wrong. I have no boost gauge yet. Day 3 I was getting good boost, still fluttering, but it would get boost cuts and back fire or misfire. As I got on it a tad today to speed up the car started sounding and acting like it was all motor and no turbo. I'm now idling between 2.5-3K RPM and am running very rich. The whole car is filled with fumes. The car has a replaced SR T25 turbo, Z32 maf, Walbro 255, gapped spark plugs to .29-.30. The car is untuned. What's my problem? Was thinking of Hydrolock but unsure.

See bold text...

Also, quit beating on your shit when it doesn't run right.

Put the right maf on. A Sr can't read a z32 maf untuned.
Also change your oil. I bet it's flooded.

You have a lot of issues buddy. As previously stated. Remove z maf, replace stock components, and get a boost gauge and wide band to monitor

Then work on upgrades and a proper tune or ecu

Untuned? You're lucky that the car is trying to save itself and run rich rather than lean.

Get it tuned and a boost gauge, then come back and post your results.
