what a great read this thread was - educating myself on these larger capacity rb's is very interesting & now makes more sense why the r35gtr has gone the route of increasing cc's!
after reading this thread & talking to ben from racepace...he obviously knows his engines.
i may have missed it but is this engine in a gtr with the rb26 head?
john (JFKGTR) - did u get my pm
1st engine dropped compression in no. 6 (collapsed ring land)
2nd engine dropped compression in no. 2 (probably collapsed ring land, unknown as yet)
being cylinder no. 2 chances are that maybe no. 2 injector could be partially blocked as it is unusual for this cylinder to go, usually its no. 5 or no. 6 that typically let go which run the hottest being at the back of the block
gtrs - pfc, tomei type b pon cams, 700cc injectors, 362awkw (need to confirm boost level)
gtss - pfc, tomei type a pon cams, 700cc injectors, 325awkw @ 21psi
both tuned by crd
i think i might be wrong as chances are if i ran 362awkw (gtrs) & 325awkw (gtss) that i was running a higher boost with the gtrs setup.
i'll look at my old dyno sheets & post the results
my 1st engine had gtrs turbo's and it let go after 4 months, running 362awkw. aust delivered gtr with genuine 100,000km (full log history).
my current engine ran 325awkw & let go after 6 months but i expected this after my 1st experience.
both botom ends were factory, untouched & had done close to 20years!
probably nick @ dart, he built me other engine (& yours) and i was very happy with the workmanship!
dart automotive treat my car like it is 1 of theirs!
stock bottom end & now requires a bottom end rebuild (factory gtr bottom end is not engineered to handle this power, it has happened to me twice now)
in terms of rwkw i think you lose 10% in awkw mode, so maybe call it 350rwkw?
paul (dirtgarage, aka gtr wikipedia lol) can confirm this if he happens to read my post
i didnt expect u to lose the car on that last corner - looks like a nice track with water views reminiscent of phillip island
were u shifting @ 8000rpm? who said rb30's cannot rev
you're not running a blow off valve right? the sound of turbo lag reminds me of my previous 3 cars & i love that sound!
what fuel system & injectors are u running?
yes it was the plasma bores that i also heard
i agree with ur comment about the 15k rebuild...i guess its like an rb26 running 295awkw and hoping to get 100000km
(this is what the r35 achieved on crd's dyno)
