BoostdR

I am using the SR on the track and very imprerssed with them. I have completed 3 track days on them. No fade, very kind on my discs and minimal dust. They don't heat up my rotors as much as my EBC green stuff..less bleeding brake fluid. cheers

HKS Vcam......

Interested in the Tomei GTR sump baffle. Does it have gates?

Won't find a better cooler than this..... Flared inlets reduce restriction and improve response The flow through tubes give the advantage of less distruption to the radiator...meaning you can have a thick core and minimal effect of radiator performance...unlike other brands Trust have nothing on ARC in fact no other brand does.

COD would be the go here boys. everyone wins

I have built a RB31/26DETT 824hp -engine hp 264 9.8 HKS Tomei Dumps 3" x 2 (no mufflers) 530ft lb @ 2800rpm 22psi max Garrett -10's Ported std manifolds BP98 with 10% methanol Motec I have built and own RB31/26DETT 455rwkw 264 9.8 HKS Tomei Dumps 3.5" exahust 2x mufflers 1bar boost @ 4000rpm HKS GTRS Chinese Manifolds (soon to be 6 boost) 20psi (run out of injector and fuel pressure) E85 PFC with Z32's

Port matching will aid "max" flow. Leaving the manifolds std with smaller turbo's is not a bad idea as response can be effected by opening up the mani outlets. If the std mani's aren't a great restriction at your power level ie: less than 2.5 x boost pressure. The effort may not be worth it. If you would rather 10kw up top rather than the mid range then go for it. I would be aiming for average power(nice meaty mid range) matt

Yes! a good point here regarding restrictors, they will flow varied amounts proportional to oil pressure. So they -all- need to be changed to reflect your pump pressure. Not sure why CRD made this comment because it doesn't hold true for a higher pressure pump. I can understand it is rarely an issue however---the head is much more sensitive "Hey Waza_GTR Turbos normally have a 0.8 - 1.0mm oil restrictor in them restricting oil flow / pressure through them so this should not have been a drama. What turbos were they?" I had a long chat with Keir at Willall regarding this exact issue. To run a higher pressure higher flow pump 7bar or above the head restrictor needs to be 1.2mm in an RB26. Granted the turbo's are less sensitive to this issue but some can have induced turbine ring leakage with increased oil pressure and no other change. Some cases require a regulator or a modified turbo oil line restrictor. The turbo oil feed banjo bolt from the block has one...also the turbo inlet on the ball bearing cartridge turbo's should have a .85mm restrictor fitted. So high pressure is fine. Just get your restrictors right or Reduce the pressure and use the std turbo restrictors and tomei 1.5mm block restrictor( for over 4bar and track use) *of note the MInes triple flow cam baffles don't do a great job of returning oil to the head after it gets in the baffles. If you have to much oil in the head from the wrong restrictor and pressure these will make the problem worse. The std items have drain back provisioned. Matt

Totally agree. Have to do the same thing. Have a Reinmax pump running 8bar above 3000rpm. Will aim for 80-85psi max Stock is 4bar N1 is 5bar Matt

Hey Dennis. I have the older Nismo Gmax twin Pull. has minimal shudder....only when slipped for more than 5sec...and gets warm...ie up a hill in traffic. Is holding 455rwkw no worries. A trap for young players was the flywheel is thinner than std meaning you need to shorten the bolts....couldn't work out what the rattle was for ages...6 track days later... has minimal rattle now...much less than my OS twin

R33 GTR Dual exhaust Must be 70mm x2 or larger Cheers Matt 0413023669 or PM

R33 high flow, 270rwkw and full boost before 2500rpm. It does surge a little.

I have a reimax oil pump on my Rb26. You list 5kg @ 6000rpm and 7.2kg regulator...doesn't make sense. My pump sits over 7kg at any rpm over 3000. 8kg cold at idle and 4kg 80c temp at idle.

Just noticed your comment about a solid lifter kit....for the cost of Valves, retainers, seals, springs, buckets and fitting it would be cheaper the buy a RB25DET NEO head which has solid lifters std.

Don't waste your money on a new block! Bore the old one to 87.5 or even 88 and get it sonic tested. Which ever bore/s are thin-sleeve them. Its usually number 3. I run a big bore RB30/26 (bigger then 87.5mm). With the sonic testing it takes the guess work out. Spend the money on more worth while things like balancing and a tomei oil pump that has an external pressure releif valve adjustment( just don't forget the 1.5mm(hydraulic lifters) block to head restrictor. With the money you saved get a GTR crank and pistons ( I would use stock GTR rods for your power level and CP pistons)...with the extra capacity from the larger bore you would be rewared in response and torque. I wouldn't be to quick in dropping the comp level either...Your tune is what determines detonation, the comp level will effect when peak cylinder pressure is reached but the tune determine if it will det. Your off boost response and fuel econ will be better with a comp of 8.8 to 9. I wouldn't use any less than 98 octane for 500hpatw however. Make sure you get the head cc'd and piston dome cc's calculated properly so you can actually work out what the comp is. It does change with bore size also! The comp ratio stated with your new pistions is only a guide. You won't need a crank collar on a 33 GTST or 33 GTR crank. Supertech valves are fine, but if the old ones are fine, don't waste your money. For drivability and good idle/Vacuum go low duration cams and medium left. Tomei Poncams 256's or some re ground GTR cams (to hydraulic profile)...but best to go with the pon-cams to keep the VCT and ease of installation. Lastly get a good sump which has internal baffling. Matt

Good coolers, great price.

About 140kw ahead @ 4000rpm.....crickey

The pressure built up would cause oil to be forced down the valve stem seals...also more likely the pressure in the sump would restrict the turbo oil return and pressurise the turbo housing forcing oil out the turbine oil ring. I wouldn't expect it wouldn't damage anything in the short term however if it has been doing it for a while the caked and burnt oil could have worn the turbine oil ring.

I have gone through 12 std gearboxes. I now use with Redline gear oil. Haven't broken a box since....

Prefer registered but send me the details

Here are some current pics. The paint to cover up the scratches is not the best match hence the price drop. Matt
