S-AFC Tuning Question

When i got my car serviced, oil, fuel, air filters, oil. plugs regapped to 0.8mm, also got a 2 stage turbosmart boost controller put in.

I have stock, IC, injectors and comp at the moment.

I wanted the boost set at 9 psi low and 14psi high, but i could only put the high setting on 12 psi because it was pinging.

I will be getting a S-AFC soon, so i wanted to know if when i get the S-AFC and get it tuned could i run 14 psi on high boost or whould it still ping coz of the stock IC??

Also whats the setting on their to stop the car stalling coz i got a Blitz Atmo BOV which is a pain in the arse to drive with in heavy traffic.

Also i got 150kw@wheels with 12 psi boost, pod filter and 3inch full exhaust, what can i expect to get with the s-afc tuned?

Okay...I'm no mechanic, but there seems to be alot of this at the moment. My guess would be the cold weather coming in, as boost tends to rise a little with cold air. And if you right on 12psi it wouldn't take much to exceed the computers restrictor.

A boost controler would usually be placed inbetween the intake and the wastegate actuator...I mean the line which runs to the boost solnoid which gives the boost signal to the computer (?)... I know mine cough and got upset until I removed the line....it seemed to boost heaps better and went to 13 instead of 12 and coughing.

Again...Don't take this as word of law.

      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.
