hey, i have bosch 040 intank pump in my 32gtst and recently went to a drift practice day at baskerville in tasmania, halfway through the day my car started cutting out at high revs or high load, by the time i got home i couldn't rev it past 2500rpm or put much load on it at all and the pump was buzzing its head off

the bosch 040 had shat itself, i now have a new one in there and all is good, but im worried if i go back to the track again it will happen again.

some people have told me i should get a surge tank, but i cant see how it could run out of fuel(enough to stuff the pump) with over half a tank left

ive done the voltage mod and am running the pump off my own relay and it has 14volts going to it, could this hurt it?

but maybe i just got a dud pump

very grateful for any help!

for those interested heres a vid from the praccy day, my first one so go easy!!

I have an 044 mounted intank with a new sock but it's mounted much lower than the original, had a track day and a couple of skidpan days with lots of sideways, no dramas whatsoever. It will even run down way past the E line on the gauge and still not splutter under full load.

the 040 has the open base, therefore no sock.

One can machine up a fitting to suit, as per a 044 DIY i did :(

Odd, might be worth seeing if you can send the dead pump to Bosch Australia for a pull apart, and diagnostic. Maybe the pickup is too low lol.

    • Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.
    • Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.
    • I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.
    • 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.
