Hey Guys,

I have a Series one r33. My current mods are Power FC, FMIC, turbo back exhaust, splitfire coilpacks, Walbro 550hp fuel pump, Boost controller, z32 afm, pretty much all the basics.

It makes just over 200rwkw in its current state at 14psi. Just wondering what would be my most effective next modification?? I didnt want to spend thousands on turbo upgrades just yet, definetly down the track, I was thinking more along the lines of a cam package? Im not too familiar with what sort of cams will be right for my application. Just wondering about your thoughts and experiences with what works etc.?? Details and brands would be much help.

Any help and input is appriciated

Thanks

Ok so I may have to just bite the bullet and stop being a tight ass!! lol. The highflow idea sounds good, I already have some 550cc injectors here in my garage that i picked up a couple of months ago, and the 230 to 240rwkws is probably where i want to get to next.

replacing injecotrs in a RB25 is a bitch.....i did mine a while back and never doing them again.....no skin left on my fat hands lol....but yeah 250 with a responsive turbo is the way to go for a street car......555cc injectors with a highflowed turbo and a really good tune should see you over the 240 mark no probs...

Yeah tell me about it. I had my stock ones cleaned a while back and took them out and put them back in. NEVER again!!! Ill just pay my tuner to do it. Itll take him half the time most probably!!

Ok great so high flow turbo here we come. Who is generally the best to do high flows?? Any in Brisbane??

There are a couple of places not sure if they are in Brisbane though.....GCG, Hypergear, ATS, MTQ....so a few options

MTQ in Brisbane can do them, no idea on price or specs though, Probly better off to get either a GCG or Hypergear one.

I had a MTQ high flow and it didnt make anywhere near the power of the GCG / Hypergear ones have.

Its not too bad, pretty responsive and doesnt chew the fuel (450-500kms per tank depending on the weight of my foot), It made 205.6rwkw but my knock level was around 50-60. So I think he played with it a bit, the final result was 201.4rwkw and max knock was around 35-40. Ive had it tuned previously at a reputable workshop (wont mention names), and it made 185rwkw with knock at about 50-60 so it was then retuned at my current tuner (BPS in Brisbane). I havent been in any other skylines with pfc so i wouldnt be able to compare.

Id be happy with 250rwkw, just so it stays reliable because after all it is my daily driver too.

      R32 goes out in right curves

      That's true. However, this problem has started since the tuning. First time with the return journey from the tuning. But yes, the pipe was clogged with dirt and rust. That was certainly due to age

      Great info @tidi0x  Will definitely be handy for others and maybe me if I decide to keep the shit box H pattern.

      Bumping this up one last time.... I wanted to follow up on the clutch slave issue. I realized that what the issue comes down to is the pocket is flat milled, and the cylinder does not want rest flat. So in order to mount it correctly you will need to make a spacer for the fingers so the cylinder is floating. I took two plates of aluminum, drilled some holes and was good. I did still need to make the relief cuts in the bell housing, as even with the spacer the bleed section still interferes. The OE bell housing the mounting holes are raised from the housing.

      R32 Gtst - Track Car

      If the event in USA goes ahead will be interesting as it seems the rules will get more cars over here. Apparently the track is laguna seca too. Yeah s15, if I get a the lower dash trims, centre console and change front cross member to standard LCA position will fit clubsprint. See how rules are as i would rather do complete widebody than a bolt on flare to run the 295 with proper clearance.

      If the car is legal height I can't see it being an issue. Found a thread on reddit that might offer some insight.   I got a ticket from a copper in QLD for my S15 being too low. They had this wheel thing on a stick that they put under the car and it hit my exhaust. Anyhow went to an exhaust shop to get the exhaust tucked up/hung a little higher and I wound the coilovers up a smidge. Don't think I even had to go back to the police station unlike when I got defected for having a carbon bonnet when I brought the S15 from the ACT to QLD and had to replace it and then rock up at a police station and have a yougish female officer who knew nothing about cars confirm that I had changed bonnets. Should have just painted the carbon bonnet yellow to match the rest of the car lol
