i also wouldve thought thered be more in it at that boost, bearing in mind i was initially a bit disappointed with 220rwkw from my old 2530, until i realised it sat next to or beat cars with 250+rwkw! while we all like to compare power figures side by side, at the end of the day it is just a figure and its how the car drives that counts.

Mark at MRC think something is holding me back some restristion. I dont expect much more from the turbo. There is heaps of mid range and top end in this turbo.

Injectots i have are apexi 555cc and bosch 044 pump with surge tank and standard pump running in boot.

It was a really hot day during tuning etc, not sure if the dyno figures takes that into equation but it was 45 degrees in the dyno room and didnt have a fan blowing onto the intercooler.

Will hopefully be out the creek on wednesday to run so if people are keen lest get a bit of a crew there. would not mind matching it up with a few others cars.

saw boro's car last night......seems to pull really well

lets wait and see what it does at wsid

PS. Dont wear the same heavy shoes mate :P

Yogi will trying to get off work for wsid. Yeah have been trying to take it easy, its pretty hard tho. should come to the creek.

power sounds right to me, its a gtrs not a t67 or something what do people expect

people expect more than 250rwkw over 1bar, since thizzle set the standard with his 250rwkw at 1bar! :(

but without cams i wouldnt expect much more than 250 even over 1bar. I wouldnt think thered be much more efficient flow left, if that even means anything..

Just took it out for a run now, first cold night since i got it. on 1.3 bar boost at high rpm engine cut-out light comes on, was told that this is pinging although i cant hear anything. going to run it back on dyno to set timing back a few degrees.

I am sure thizzle made 250kw @ 1.3 bar, it is impossible to make it at 1 bar.

i would be very surprised if it made 250 at one bar, but then again who knows due to the difference in dynos.

anyway croat, if the engine light flashes it does mean that the power fc has picked up noise that comes up on the ping reading as (usually) 60 or more. if you have the hand controller you can check it next time, although it might have been a noise other than pinging.

well 250rwkw at 1bar was what he posted after having it tuned at BD4s, only going on what he said. I used to run up to 1.3bar with my 2530, but then when tuning the 2835 my tuner said he didnt want to go over 1.1bar till i did the headgasket. Maybe i could run higher boost with the small turbo coz it would always drop right off at the top end, not sure.

nah i never tuned on 1.3 boro...plus i had slippin clutch. and rushed tune cuz i wanted my car back i think i gave bd4s like 3 hrs on a friday arvo...your 1.3 is alot diffrent to mine man :) somethins holdin it back...cuz i pay out the ass for jap tuners and mechanics maybe ??on 1.3 i woulda got 260-265...your engine wasnt pingin man its runnin very smooth.. it could be tuned a little more i think...

post up the dyno show folks the torque lets see if they still would be dissapinted...

time to take it to yoshi :kick:

btw did ya block that bit yosh said to block up?? cuz ur using that catch can with the air filter on top??? wich results in you loosing boost..

this is about the same power alot of people are making with the GT-RS on sr20det's, although with cams... they dont seem to flow much more then 250rwkw, if thats the power output your after, then the turbo is perfect for responce/power

if you go for some radical duration on your cams you may see more power... the turbines on these turbos are relatively small which does choke them up top when pushed

I got a GTRS installed last week and tuned on saturday and got 255rwkw at 1.2 bar still have standard air flow meter so should be a bit more in it when I get it retuned with a Z32 or something similar. Other mods are full 3 inch exshaust, FMIC, PFC, nismo 555cc injector, exhaust cam, lightened flywheel and ceramic clutch, spitfire coils and bosch 044 fuel pump. Also great response and enough power to keep me satisfied and scare the sh!t out of my mates, also makes the car sound awesome as well.

    • 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.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • 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
