hi mates im just thinking about my haltech that stopped working in my rb20 hilux. does the map sensor get power from the ecu or somewhere else? its a external 3 bar haltech one.

im trying to determine how dead the ecu is before I send it to haltech. it has around 5 volts at the map sensor wires.

ecu does nothing else in regards to spark or injector pulse

I haven't got a cable to hook up to laptop to see if anything is happening :( im hoping I can get the tune out of it once I get a cord or take car to the shop then send ecu away to be repaired.

If you send it to haltech they will almost certainly be able to save the tune. 99% sure

I had a flood damaged honda Ecu, the hondata annex board was f**ked too but we still pulled the tune off it.

As for what Simon said, you could get a nistuned RB20 Ecu for very cheap these days. But then you'd have to install an AFM..

      What brakes on R34 GTT(Europe)

      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.
