Leave them factory... and buy another black set

Google it There is a brilliant one for skylines on there. CBF doing it now... Ill have a play tomorrow after work

Sponge bob 2's are coming Mick

^^ sounds like the pump is mounted WAY too high!

9.6 mm won't fit in your head though.

It's well known the workshops that have "happy" dyno's

If you want throttle response (which is something you CAN'T see on a dyno) no bigger than 260. My 260's spun to 8000 on 25 psi without dropping off, on higher boost ( turbos were out of puff) peak grunt was 6500 but only lost 15 kw by 8000 rpm).We are going to try a smaller duration and higher lift cam soon. ... Awaits micks post

I personally wouldn't go 272's. You're not revving to the moon! Send a PM to XKALABA. He will have something VERY interesting to say about 250 vs 260 degree poncams.

Must be that not small exhaust!

Checked the ignitor?

^^^ is your head relieved for big lift cams?

2.8, -5's.

We must tune them richer over here

Forgot about this thread. Time for a little update; New setup; GT Block Tomei 2.8 (87 mm pistons with Titanium top ring) 9.0:1 compression ratio 260 at 10.85 mm cams. (custom grind with a much more aggressive ramp rate than a typical "Jap" cam.) Full effort HKS/NAPREC head. (1.5mm OS valves, NAPREC CNC machining, intake squish pad removed, decked 1 mm) Ported manifolds (to head and turbine housing) ID 2000 cc injectors Twin 044 feed pumps and single 044 lift pump Nismo 0.9 mm head gasket Nismo Plenum Nismo intercooler Tomei series 1 dumps (72 mm internal diameter) Garrett -5's with ported turbine housings Racepace motorsport twin 3 inch exhaust Blackbox ECU (Built in conjunction with Unigroup Engineering. This ECU is yet to be released for GTR's) Ethanol flex fuel setup Ross Tuffbond crank trigger. (Timing is no longer taken from the CAS) Stock airbox with a $10 paper filter in it. United E85 Modified turbo intake pipes Made 472 RWKW with the EBC on (highest was 474). Peaks at about 28 or so then trails back to 25.5 ish top end. With the EBC off (20- 21 PSI) it made 441 RWKW. Tuning for very strong midrange midrange more than anything. On PULP it made a an easy 425 rwkw at 22 PSI IIRC

I was more after the shape of the curve. Still good, be interesting to see what you pull

Lol

^^ got a dyno sheet?

C spec will piss that in!

How much grunt are you chasing?

You bought a Tomei 2.6 then when it pops rebuild with a 2.8? Is that right? I'm confused haha

Have you gone 2.6 or 2.8?

How was the crank when you pulled it out? Lol

Good excuse to build a real engine
