shanef

im shanef reason theres 2 plates that theres 2 separate bolt hole configurations. 1 for the rb26 plenum and 1 for the rb25 head.

redline is too small, will need to be 8000rpm or more

yes im a fan too i certainly do - http://www.skylinesaustralia.com/forums/Rb...36#entry3686536

as per the other discussion, i reckon it'll be cam belt flex affecting the CAS up in the revs. get a scatter plot of the CAS vs rpm Heres some info: http://www.gtr.co.uk/forum/77187-highest-h...html#post696694 http://www.gtr.co.uk/forum/52458-rb30-engi...html#post610782 - post 255 and post 259 http://www.gtr.co.uk/forum/641917-post320.html

beauty, thanks for the heads up

Thats good to know. Did you end up using that 3 stage on anyting yet?

Further more to the acumulator, its only really a band aid fix/in between a wet sump and a dry sump The other option which not many people have thought of/put into practice is using an external belt driven oil pump (aka single stage dry sump pump). I've just ordered one from BDG for this car im currently building, and it'll cost the same completed as if you were to buy a JUN pump (with the way the current dollar is, a jun pump is atleast $1500)

you'll be extremely lucky if you can find a set in the country. best bet would be to source them from the states

well ur not going to make 500hp and keep it alive without them

piece of piss to put it bluntly. you'll need forged rods, pistons, big port work, o/s valves, poncams, inlet manifold, gt35r with a decent manifold (6boost is the best), radiator and oil cooler to keep it alive, jun oil pump and oil system mods, fuel system thats up to the task. or in money terms around 25k

dan from elite racing got them for me (erd.com.au)

id be a bit concerned with the lifespan of that oil pump. They should have more clearance on them than that. Theres something obviously wrong with it. The way that pump is, i hope you dont plan on making any half decent hp, i dont believe that pump will last too long. The most likely way of it failing would be the gears cracking to due abnormal wear to the outside face of the gears due to it rubbing on the housing. The housing is stationary and the gears are moving about the crank. For ease of mind, i'd pull the motor back out, pull that pump off and replace it

i got them for $230 delivered cams in this head are fairly sizable, 270/280deg 10.8lift

the only ones i could find were tomei's. i reckon arp make them but i couldnt find an arp listing anywhere (only for porsche they list)

somewhere between 1500-2000. its hard to know the final cost before you actually get them made. They aren't high on the list at this stage, but if there is genuine interest they could be ready to go in about 2months

You could say that yes. But these have bene designed form the ground up, and hanvt been based on any japenese pump hmm yes good point

Solidworks Both. Billet pump (with external pressure relief) and upgraded gears.

if theres genuine demand i could push production of mine?

are these fancy pistons with 4 rings? or is it a new 8cyl?

yep thats the one. i stupidly sold it with the std throttles/plenum without realising i need it with the hypertune plenum

dont spose uve got a spare plenum intermediate plate laying around paulie?

Be realistic with your prices. No one is going to pay $88 per set of rings when complete sets of pistons with included rings are near the same money.

got any graphs paul? whats it like under the curve?

thats what i thought too, must be a stroker of some form
