[bubbabooga]

A31 cefiro

engine

fully forged rb30, crank collar and refurb rb25det s2 oil pump with higher pres releif, atmo catch can with drain,54mm ally rad, mega ducting, r32 rb25de head with standard de cam's (uhh ohh ) rb26 valve springs and adj cam gears, mild port work by the looks of it, custom intake mani with q45 throttlebody, 3 inch pipe work, isc cooler core, 4inch intake, kn filter mild cai, ase high mount stainless twin scroll mani, 50mm progate, garrett twin scroll t04z 8.2 rear housing, 3inch dump pipe into pretty dodge 3inch straight pipe exhaust with one resi then under diff into a oval muffler at back (the slight angle's down the exhaust are just like slightlly angle cut straight pipe's welded up ) screamer angled threw front left wheel, sard 800cc ts injectors, standard rail, fpr and lines, walbro intake lift pump to 2lt surgey with 044 hardwired, haltech e11v2ecu with boost controler etc, genuine loom with split fire adapter harness for a31 onto splitfire coilpack's, bcpre7 0.8 copper plugs..

driveline

rb25 box with nismo g-max twin plate clutch, nismo solid short shifter with strengthened pivot ball rb25 modified tailshaft, (after a brand new one piece tore 25 holes threw my trans tunnel and spunn the previous gearboxes bellhousing on the block, very first track day on the very first lap. WORST DAY ) welded r180, 6 bolt shaft's.

356rwkw on 21psi, bp ultimate fuel, 750nm.limiter at 7600rpm, tuned by simon podlewski at morpowa SA.

iv seen fair few similar setup's running much better number's on lower boost.

like trewella slide fx ceffy makes 80hp more on 6psi less boost with near similar setup.

have semi plan's to clean up and port match both manifolds

oil restrictor's and camtech drop in 268* 9mm lift cam's. suggestions for different inlet exhaust cam degree's welcomed?

any critic's/advise on any of the setup or parts welcomed

cheer's alot tom

also its had a annoying as slight intermittent misfire for quite some time now, cant put finger on what it could be.

is their a way of testing for fluctuation of the cam angle sensor signal?

as iv heard its comon with belt harmonics etc on nissan cas to bounce around the timing.

my timing belt layout is a copy of the osgiken design and the timing belt when cold and blipping throttle the belt bounce's and slaps the top of the lower timing belt cover so i know the belt is quite loose and slappy/bouncey.

[Dobz]

Hmm.... shallow and pedantic.

But seriously tighten that belt up quick smart if it's slapping around that bad, the last thing you want is for it to jump teeth.

[DVS JEZ]

Tighten the belt. The rest sounds good to me,

Was the slide fx ceffy dynoed at morpowa or a different dyno?

[R31Nismoid]

Just need more boost. T04Z and only 20psi = pointless.

Screw 25psi into it.

[TiTAN]

why did you sticky the thread?

560hp @ 15psi out of a T04Z? that sounds like a happy dyno.

Agreed, sounds like a wives tale.

Back on topic though, 21psi through a t04z on a 3l should be making a fairly comfortable 400kw....

[bubbabooga]

car's been sitting for over a year fixing the tailshaft mishap so hasnt been used stuff all, but i do plan on tighening the belt up asap.

what would be symptom's of a cam gear skipping a tooth? without smashing valve's into pistons that is. lol

adam "borneo" trewella's cef is tuned over in wa by glen camble. not sure on the dyno they use, that was just an example of a similar setup.

also note his car is running a neo 25 head, state's its pushing 410rwkw on 17psi.

how badly do you think the standard 25de cam's and dodge 3inch exhaust would be chocking up my setup?

it's a fair drive to get it down on the dyno but i plan on asking him to drop the exhaust next time its on their.

so 21psi still isnt really into the efficiency range of the t04z?

cheers guys!

[R31Nismoid]

20-21psi is indeed just cruising

and 17psi/410rwkw is not realistic

Also DE cams and a 3" exhaust?

Two notable problems on top of the others you have...

[DVS JEZ]

I needed 25psi to make 419kw with a t04z on my old rb26.
