Reliable build plans for 260kw? anyone..

[Godzillars Bro]

how can i achieve around the 260kw atw's mark with a rb25det? what mods will i need done to do this and mods to make it reliable?.

1 how much power can the internals handle in rb25dets?

2 how much power can the fuel system handle? pump,injectors,regualator)

3 what hp figure is the standard t3 turbo rated at?

cheers.

Internals can handle 450BHP,

Fuel system about 220RWKW

I wouldn't be using the standard fuel pump from an RB25DET with 220rwkw (370bhp). It is only rated at 300bhp (223kw at the flywheel).

It is VERY important to get a fuel pump that not only supplies the appropriate pressure and flow, but is also less likely to fail than the std item. The fact that my car no longer has it's original motor is a testament to that.

But in order:

1 how much power can the internals handle in rb25dets?

If tuned correctly, I would suggest that they're capable of reliably making 400 engine hp.

2 how much power can the fuel system handle? pump,injectors,regualator)

Injectors will prob be maxing out at 350 engine hp, regulator....dunno....pump piss it right off.

3 what hp figure is the standard t3 turbo rated at?

Firstly it isn't a T3. It's a specially made unit manufactured for Nissan by Hitachi. It does use a T3 flange and this is where the confusion comes from. I believe it is rated at about 340hp.

Heavy duty Clutch - $1100

Front mount intercooler - $1500

Fuel pump - $450

injectors (altho its been proven to get 250kw's out of the standard injectors, get bigger for reliability) $1000

Turbo: HKS 2540 will get you their with good tune, or if you want a more power go for the GT3040 $1500 - $3000 new or second hand.

high mount exhaust manifold: $2500

maby aftermarket head gasket. (depends on what boost you want to run) $400

Ecu : maby power fc - $1200

wastegate - $500 - $800

hks exhust cam gear - $250

3" exhaust etc: - $1500

Thoes prices are just guestimate. theirs most likely stuff i've missed

get a set of cams, tomei ones 256 - 260 or whatever the ones sydneykids says to use

this will increase torque over the entire rev range and on boost too

the 2540 will just be laggy, if you want the same power level get a r33 highflow it should match the power of the 2540 without the lag.

the hks3040 brand new from nengun is around 2700 not including delivery. look at a gt30 with a gcg manifold instead, probably better and more cost effective, get an external gated turbo too. or even a trust kit which includes turbo, wastegate and manifold. i wouldnt just stick to hks just cos

ecu probably power fc, hand controller and boost controller kit

other ones like wolf3d dont use air flow meter so that solves your air flow meter problem

stock r33 gtr intercooler should be ok for upto 300rwkw vs brand new aftermarket one

youll need a new or good/better clutch twin plate as stated

i would do injectors and fuel pump and fuel regualtor to be sure to be sure, saves stuff going bang

also you *may* need a different air flow meter, depending on how much boost you run, the stock 33 one will max out and only show 5volts and give the wrong reading the ecu so the ecu will underfuel

i dont believe head gasket is needed, check out below threads

http://www.skylinesaustralia.com/forums/sh...ight=power+2530

for some previous configs and power outputs. get a full exhaust, hiflow cat, hiflow dump and front pipe

my info is mainly from searching on here and reading up and learning myself so some of it could be slight out or incorrect, sorry if it is

Like anything the rb25 will last as long as u treat it well. Dont drive full throttle and like u just stole it all the time and it will have a long life.
