Power Expectations Rb30det Fully Built

[den001]

hey all...

i was wondering if all of you people that have had experience with all different turbos would be able to shed some light on turbo differences on a rb30/26

im building the car for mainly drag racing but the occasional run around a race track so im not really worried about lag, well to a extent, i would honeslty say id be happy with full boost around the 4800 5000rpm mark..

i have been reading the posts every1 has been taking about their rb30s and their turbos and the power that yous are making and there is not really much info on anything bigger than a 35r, there is a fair bit of info on to4z's as well but what do you guys think about ITS turbos and billett turbos or turbonetics gtk turbos???

i maby be going for a billett turbo which is a t76gts rated to 900 - 1100 hp with a open exhaust housing in a .96 option

my motor stands as is

rb30

main studs

headstuds

spool rods

aries flat top pistons 8.6 comp

all oil mods completed

jun oil pump

jun collar

custom alloy sump, trap doors, baffles ect,

modified pickup

rb26 head

massive porting, knife edged ect ect,

throats also ported

1mm or 1.5mm oversidzed stainless valves, im not sure, but its one of the two

hks 272 10.2mmlift in and out

hks step 2 valvesprings

6boost manifold

1000cc injectors

ati 1000hp harmonic balancer...

will all be tuned on autronic sm4

i will turn the motor to around 7500 8000rpm so im hoping it will make some serious power......

i really would like to know peoples experience with a setup like this and what yous recon it would withstand and just turbo recommendations and power outputs yous recon it will make thru a manual.....

thanks guys.

have you looked into the HKS T51R ball bearing?

Mate had one on a supra, made 480rwkw and was full boost by 5000rpm in second gear. (bush bearing version)

Ran a 10.81 with lots of traction loss. (Search FUS01 on youtube)

Anyway, the supra had minimal mods - Haltek, Water Meth injection, FMIC, Injectors, EXhaust manifold and EX gate, and standard engine. Was extremely reliable, compression was still very high after a lot of drag runs. Damn toyota building bullet proof engines and greaboxes.

Anyway, look into that, might be a good start.

Have you dealt with the oil control issues of your engine?

My engine used to be in a VH commodore with a pair of 2540s on it, made 365rwkw @ 21psi and also did a 10.81 with no loss of traction.

I now have the engine and am putting a GT35R on it, the commodore is getting a HKS 2.8L with T51R-SPL.. should be pretty mean..

I'm only aiming for 400rwhp for now with headroom for more later on. My mate is aiming for 800rwhp with the T51R..

Nice setup Sounds pretty much like you should be looking in the territory of things like a Garrett GT4294R... would be a crapload of fun with a setup like that!

A guy over here in NZ with a 240Z running a built RB30/26 hybrid running a T51R-SPL making 661kw @ wheels at 7500rpm on pump gas - dyno plot here:

Car has done a flat 9 @ 152mph so far on street legal tires.
