R34 Turbotimer, Immobiliser And Boost Preasure Problems. Please Help

[jorgo90]

Hi everyone,

I purchased my 1998 R34 GTT about 7 months ago, and all went perfectly for about 6 months. Recently I have run in to a few problems which I really need some help or recommendations on as to what might be the cause and what to do about it.

The car has a aftermarket alarm turbo timer immobiliser(not sure if it is all one unit or seperate) and a power fc which i think may be relevant to the problem, but also has aftermarket pod filter, front mount intercooler, and a few other bits and peices.

Problem 1:

At the end of a trip, when I turn the key to the off position, 90% of the time the engine will either turn off temporarily then try kick start(crank) itself, and when successful runs down the turbo timer and then turns everything off properly, or it will turn off (sometimes sound like its trying to start) but doesn't kick start/turn back on, but my boost controller and dash indiciation lights remain lit, indicating that the car still has power running through it and the car isn't actually off (I then have to turn the car back on by turning the key to the start position, then I can pull the key out with no problems everytime and it will run down the timer and shut everything off properly).

10% of the time it will actually stay running when the key is removed and run down the turbo timer then turn off with no problems.

This problem has gradually become worse, it use to be 10% failure rate, now its only 10% success rate of turning off properly.

I have also experienced funny business with the immobiliser where i can start the car and have it running (can't be done without the immobiliser disabled) then all of a sudden the car will sometimes beep or not beep and I put the handbreak down the drive and the engine cuts off.

Problem 2:

When driving with no boost, the revs can go as high as they want in any gear with no problems, when turning the boost on, in 1st-3rd gear, when excellerating and the boost preasure builds up especially getting towards the higher RPM, a squeel sound almost like some of the old kettles when boiling water or asif air is beeing squeezed through a small gap occurs.

Could this be the BOV, or piping, or any other suggestions?

Thank you so much for any advice in advanced.

For problem 2, i have also noticed that there is less of a "throw back" effect when the turbo actually releases air into the engine when it hits the PSI mark.

Problem 1: Piss off the turbo timer thingo. You don;t need a turbo timer. If you can't wait 30 seconds to turn it off after you pull up, then you need a patience transplant. Timers are illegal* anyway, so who needs something unnecessary on their car that can trigger a defect when you could avoid it?

* It is illegal to leave an unattended car running. Turbo timers breach this rule.

Problem 2: You either have a boost leak (split hose, leaky clamp, broken weld, etc) or you have an exhaust leak (stuffed manifold, turbo or dump gasket, or possibly loose/lost nuts bolts on same or broken exhaust stud.) Find and fix.

then you need a patience transplant.

I also need one of these, where can I find?
