Seems like people in here wanna make 20psi @ 3000rpm and make 350kw at wheels LOL

We can... ditch the RB's and whack a LS2-tt :) haha

Just keep it civilised yeh. We are talking stock comp engines as well, which makes those amazing results kind of redundant.

There are many people making well over 330kw @ 20psi on a "stock comp" motor having seen them my self and a load of them in the "RB26 Dyno Reults Thread". Few boltons and a good tune goes a very long way ;)

Hey, yeh pretty much all sorted now. Haven't had a compression test done but she makes around the 400hp mark now which is good. Been ages since I've posted in this thread, can't remember if I updated

Hey i got a r32 gtr making 287 at around 14 psi and making 320 at 17.5 psi. and its got more in it. i need a direct feed of power to my fuel pump and my intercooler is running at its max capacity and please noone go on about the coolers coz if spoken to high degree engineers and they both have told me the max airflow factory intercoolers produce.

so in saying that my car is making 320 at 17.5 psi leaning out. if use say that the gt-ss dont flow much use are wrong they are great turbos response wise and power wise. if use want big power go single or -5s but then u wont have as much response. its a catch 22.

i can post my dino sheet up if use want. its got tuned by JEZ.

Yeh I read they're pretty good. All I know is that after a good flogging in the hills she'll still be nice and cool to touch on the outlet half of the cooler and warm on the inlet side, so it should be working just fine ;)

yeh thats stock cooler but as u can see the graph hasnt flattened out so hopefully by getting a good intercooler (im saving for hks) and rewire fuel pump and abit more boost i should get better number. im happy as is, JEZ did a good job tuning the car runs all day everyday without any problems and in the end thats what u want.

maybe your engine is running out of puff. .

Whos is?

I dare say you will be wasting your money on a bigger cooler at that power level.. If anything you will loose response for bare minimal gains up top

Yep sure am mate. I think even after a full 20mins on the track during sprints the thing was still cool at the driver side end and that was during the warmer months too

Does that mean Im not your favorite anymore? :(

Haha ;)

You wouldn't have any other videos floating around in addition to the one you have on your build thread? It would be good to see yours in action.

Here's mine at Willowbank with the N1 turbos....she'd definitely go nicer with the -9's

Excuse the pansy launches and the HD video quality :D

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
