Peter.  I want to run it that rich just to have a bit of a buffer zone as i will give it a hard time and just want to make sure its safe. Id rather sacrifice some hp and just make sure it doesnt ping. As with fuel thats the most that pump is gonna give at those afr's. Fabs gtr went about the same hp with a single 044 so im going to use 2 with a surge tank . Cams it is using are HKS 272 272 step 2 10.2 mm lift which isnt huge lift as they go up to 11.8mm on some. . As for target boost pressure this turbo should be in its efficiency at 24-27psi so thats what im heading for. Also lift the limiter from 8k to 9k when it has a fuel system to support it.

Why do you think it is the fuel pump? Have you monitored the fuel pressure on the dyno? If the pressure drops that means the pump is running out of flow capacity. With 13.8 volts via a relay and direct to battery connection the single 044 should have more than enough capacity to handle that sort of power.

:rofl:

ok cool

thats a pretty big buffer but ha each to there own and rich is safe

so by way of a the 800hp turbo at mid 20's psi with high lift cams and spinning it to 9000rpm you must be think around 600rwhp then at a guess.(or did you have a target in mind)

and if your going to spin it pretty hard what oil pump you using out of interest?

pete

sorry to hear about the box

Thanks yeh box is a bummer hopefully new one in by weekend. Im happy where it is at the moment as it feels nice to drive with not much lag and good top end. Im thinking in the mid 20's it may go near 600rwhp but until it does that i cant say what it will do but it is a good sign to be making good power at lowish boost. Its running a JUN oil pump.

I hope you have a large cost-effective supply of gearboxes...you'll need it

simon doesnt learn....

he went through about 8 or so rb20 boxes and still didnt learn

car goes very nicely, was shotgun in it same say as the dyno run... can't wait till more boost and better tune

PLUS A DECENT GEARSET ;)

      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
