Hey guys new to the forum and to forced induction cars.

Heres the problem as of yesterday i am back to driving na as turbo not spooling. No noise is coming from turbo at all.

Before you say take it to a mechanic, No

I work 6am-6pm 7days a week. Lol plus i would like to learn

Anyways could it be a vaccum hose, leak in intercooler or turbo inlet hose ?

Any ideas ? What do i look for?

I have no ideas where the vaccum hoses go from/to

Where are the 2 pipes supposed to go that come from the boost solenoid

Thanks for listening to my long winded speel.

Some help would be great

A popped vacuum hose won't loose all boost

A popped cooler pipe will.

A popped cooler pipe it won't drive at all.... Sounds like it's still running and driving, just nothing from the turbo?

Is it a stock turbo? What boost?

My money is on an exited turbine wheel too.

They'll run without boost pipework but the mixtures are way wrong, will be very rich.

AFM is sending flow info to the ecu which is way out of whack with what the engine's actually eating.

The more boot you give it the worse it becomes.

Time for a call to Stao.

R32 GTR runs without the IC pipe like an NA (Maf less). Quite fine

R34 GTT runs like an NA (slightly worse) with the Turbo rooted. No boosting..

R32 GTSt runs like shit with IC pipe popped off.

likely a high flow is your best option

When my 32R popped an intercooler hose, the car ran but ran really shit. Still sort of driveable.

When my GTS-t dropped a turbine wheel (turbo exhaust wheel), the engine ran fine but no boost, so was slow and running super rich.

Indeed.

And as above, popped cooler hose = car wont drive.

So if it's driving, logical to deduce that turbo has failed

Not true at all. Every car is different and depends on each situation, when they pop the silicone may force everything back into close to the position it should be, other times or won't. My car still drove fine on light load with popped cooler pipe. Enough to get me the few km home no worries.

Pulled the circlip off this morning and the flap opens and closes no issues.

With the circlip back on I am able to move the full arm and flap with pliers -

 

took intake pipe off and turbo spins freely by hand -

Is that with the heatshield on or off? I've seen the stock heatshield lay up against the actuator rod and stop it moving fore-aft.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
