Hey people i was just wondering what is wrong with my turbo. When i start to drive my car; the turbo start to lag about 3000 to 4000 rev and then the needle start to bounce back. some time it hard to change gear?

1. Could it be the gearbox?

2.Turbo?

3. Lose hose?

4. Service the car?

What do you think people?

Going to need a little more information bud.

Do you mean you don't get any boost till 3-4k? Is your factory bopost gauge reading positive pressure? is your car stock? mods?

i get boost at 2500 and then when it reachs around 3000 to 4000. it doest want to go any more and then it start to bounce back. the car is struggling to go.

Having recently experienced clutch slip in my R33 (to the point where it would no longer drive) this is exactly what would happen.

Foot goes down. Boost increases and car accelerates. Revs start flying up but car goes no faster, resulting in boost loss. Clutch starts to grab again. Revs drop as clutch re-engages. Boost comes back on and car pulls to redline without slipping. This happened every time until the clutch no longer worked at all. I didn't even make it home that afternoon.

You will know it's the clutch if the problem is worse in higher gears. Try it out.

    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
    • Well they got my money but they are not getting my gearbox !
