Hi there, looking for a pair of T517Z turbo's anything considered.. what have you? Cheers.

Hi guys, looking for an R34 BN Sports front bumper preferably from the gold coast.. unfortunatley new zealand sems to have uras & every other kind of kits but not bn so thinking of geting one shipped over.. if any one knows a retailer or wholesaler that have a website etc.. please let me know.. thanks in advance...

Can anyone answer this? i asked it on page 230 but got no replies.....

sounds like a usefull device if running high power levels, can someone explain the advantege of running a large plug gap like 1.1m and high boost? if you had gapped your plugs down to 0.7mm and was running a lot of boost would this be a disadvantage?

Im also interested in this, just about to order the acl ring set but wich set do i get? obviously the RB30ET rings would be beter as they are almost twice the price. can the RB30ET rings be fitted to the RB30E pistons? Cheers.

Cheers for that SK, you're the man!

Cheers cubes from memory a 1.2mm metal head gasket gives no change in compression on an RB26 so hopefully goin to a 1.00mm headgasket will bump it slightly, havent seen any thinner than that yet for obvious reasons . Does anyone know the formula for working out what the compression ratio will be with a standard 30e block & r32 RB25DE head with a 1.0mm metal head gasket?? Also is there any factory valve springs that interchange with R32 RB25DE that can withstand 300rwkw? have seen stock springs float badly at 260rwkw. would RB20DET Springs be an upgrade? or RB26 etc. Cheers.

Damn! is there any particular reason for this? i know there is varying thicknesses of aftermarket headgaskets.. is there a mechanical reason why this wont work? no budget for aftermarket pistons unfortunately this was my last hope.

Hey guys, about to start on an RB30 build & have got most of it sussed from reading this thread except when using the standard RB30E bottom end compression seems to be around 8.2:1 & was wondering if theres an easy way to bump this up a little? most people seem to be using an RB26 head gasket so would i be able to use an aftermarket metal gasket from tomei, hks or similar thats is slightly thinner to lift compression? does anyone know the thickness of a standard RB26 head gasket? ideally aiming for compression ratio between 8.5:1 - 9.0:1 Cheers in advance...

Gidday i have just brought a n RB25DET Gearbox for my 240kw RB20 powered cefiro, Just wanting to know if there is any really good synthetic oil to put in it any one has used before & can recommend? have heard bad things about redline oils unlesl its a worn box so wanting to steer clear from them. Cheers

Cubes, do you have any dyno sheets from that camparison?? It would be really interesting to see them.

Good point SK , cheers for you expertise! by the way what turbo are you using to get response like that & still make 750hp? i was planning on using a GT3540 with 0.63 exh. as response is the main goal but i only planned to make a max of 600hp. Cheers again for your help

SyndeyKid, do u mind if i ask what rev limit you use in your RB30 engines equipped with spool rods? what is the maximum rpm you have used & what is a safe limit for circuit & drift work? ever had a failure related to them? that is damn good value for money for rods that can take 750hp! Cheers.

sweet, cheers man. would going to an 87.5mm bore be getting closer to 2.7? & would a 1.5mm oversize bore be considered dangerous? i noticed most rebuilds seem to be +1mm and the most extreme i have seen is +2mm on an australian gtr.

Im also interested in buildng up an RB25DE Motor with GTR Crank & rods & some 87mm forged pistons, is there any isses with block height between rb25 & 26? ie: will fitting the gtr crank/rods raise the compression from the pistons coming further up in the bores? does anyone know what thickness head gasket to use to achieve a 9.0 comp ratio? how much more capacity will the 87mm pistons give, is that enough of an increase to call it a 2.7?? or just a "big" 2.6 if that makes any sense. Cheers.
