Just got a phone call from the guys at Boost Magazine, I entered a competition at Compak Attak by subscribing to Boost magazine for a set of Kelford Cams and I won!

Woohoo!!

Details of the cams that are available to me are here..

I think I will be going with the 264 with 9.35 lift because the engine only turns to 7300rpm MAX and has stock balancer and a N1 oil pump, or should I go 270's??

So cheers to the guys at Kelford Cams & Boost Magazine, my car is finally going to get some cams. Will do some install pics and before after Dyno Sheets to send back to kelford for feedback.

cheers ppl.

I am going to stick with the 264's. I do not rev this car so the smaller the better.

I was going to race the car this weekend but I will put it on hold untill the cams are in!

I aint sure I even needed the extra power but this is going to be a great test!

how much difference would the 270's to the 264's be

seeing that the lift is the same then it would be just change the revs where the power cuts in. I need the power to cut in as soon as possible.

Unsure if you have modified the inlet yet but with a nice exhaust manifold and inlet manifold mid 260's make their peak power around 7000rpm.

Look at Al's RB30det for example, nice inlet and exhaust mani with baby 256 cams but that too also holds well to 8000rpm and with some absolutely ripping mid range.

Mine with 265's idles baby smooth but if slightly leaned out on idle it will start to cam over 'slightly'. So tune it slightly lean on idle and then enable the o2 to pull it in when you want it to idle smooth. :D

Mine went from ~14degree's on 17psi to ~20-21degree's at peak power and made an extra ~30rwkw on pump.

Went from nosing over after it made peak power at 6000rpm to holding power flat for an extra almost 1500rpm, when tweaked with gears peak power is up 500rpm and still holds just as well with no loss in power to 7500rpm (my limiter is also at 7300rpm as Im still running the factory balancer)

The ramp rate on my 265's are a little more aggressive that the grind you will be getting

Mine have 227.9 degree's at 1mm vs 216degree's at 1mm for yours so mine run a ramp rate similar to their 270degree grind.

hrmm.. In stating that I'd almost be inclined to run the 270's. ;)

      I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?

      I somehow quoted my post instead of editing it. I regret nothing.

      STOP GOOGLING FAB9 MAKE BORG WARNER EFR KITS FOR THE NC. THEY PACKAGE AN EFR 6758. DO NOTHING ELSE. CAPS INTENTIONAL. THE BEST RESPONSIVE SETUP EXISTS FOR YOUR CAR, AND HAS BEEN PROVEN FOR QUITE SOME TIME NOW. IN B4 "BUT I WANT EVEN MORE RESPONSE, IN A SIMPLER, MORE RELIABLE PACKAGE" WHICH IS A LS.
