Going For 400+ Kw Atw.

[Tyranus]

As the tittle states i want to hit atleast 400 kw on all four wheels. I currently have 28/60R-5 turbo's in my set up.. with E85 will these puppies get me my goal? Ive been very tempted by the Garret GTX3582R so im not sure if i should keep the twins or go single?

-5's = 400awkw: Am i pushing the limits of the turbo?

GTX = 400awkw: Do i have more headroom to make more power down the track?

My setup is::

Forged R32 Bottom End (rb26dett)

Rebuilt R34 Heads (GT-R)

HKS 264 Cams

ISC Cam Gears

3.5 Exhaust (No cat or reso)

Haltech ECU

Pretty much all the bolt on's.. Now what im doing in the following weeks is competely upgrading my fuel system.

From this:

800cc Injectors

Bosch 040 Pump

Nismo Fuel Reg

To this:

Aftermarket Fuel Reg

ID 1600cc Injectos

3x Bosch Fuel Pumps

Surge Tank

Double Fed Fuel Rail

10mm Braided Fuel Lines

HKS 272 cams (not sure yet)

Haltech 4 Bar Map Sensor

Haltech Boost Controller

E85

The car is a 32 GT-R, currently making 350 on all four on 18psi (pump fuel). Either way iam going to do the mods that i stated up above. Just not sure on what turbo i should go with on that setup? Im going to try the 05's first if i cant get 400awkw ill definately be ripping them out and going Garret GTX3582R.

Cheers Sedat.

I forgot to mention: Im only into mid and top end power.. i want it to have alot of torque and power from 5000rpm onwards. Also im not sure if i posted this in the correct section lawl.

You'll do 400kw easy enough with that setup.

Been there done that.

I'd probably even leave the 264 cams in first and see how you go, you may not need 272s.

I'll give you the benefit of the doubt and assume you've not tried searching...

Because all you need to do is read the 400kw thread, or simply the RB26 dyno thread.

You'll see people, many people, have put 400 down with -5s and E85...

Was 400awkw on -5s in the reliable section or was it border line ?
