General Power Output - RB26

[Guest Nismo_Freak]

Decided to just dump the 26 into the 240SX (200SX).

Heres the mods I will be running:

R32 GTR Motor (Possibly R33)

R33 RB25 Tranny

Aluminum Single Peice Driveshaft

Hardened 4.11 Rear End Gears

Kaaz 1.5-Way LSD (still debating which to use)

Blitz Skyline FMIC w/ Custom Piping

Apexi Intakes w/ Cold Air Induction (try to encase the filters w/ box, if not I'll just duct ambient air)

Blitz SBD iD Boost Controller

Blitz Auto Timer

3" Custom Downpipe to 3" Blitz NUR Spec Exhaust (no cat)

Haltech E6K Engine Management (moderately tuned for power, still want car to be somewhat reliable)

255Lph Walbro Fuel Pump

RX7 Oil Cooler

I believe thats about it for the mods. Im going to use stock turbos for a while and later upgrade to twin HKS2530s.

I'd like to run about 1 bar if that is safe on the fuel system. I very open to opinions and suggestions. Let me know how this stuff works out on your GTRs.

I'd like to get an estimate of what kind of power I would see at maximum SAFE boost levels. I'm perfectly willing to sacrifice power to maintain safe engine operation.

I need a suggestion for a clutch as well.

Thanks guys!

Just noticed I posted this in the wrong forum... ugh... sorry!

on about 1.5bar which you should be able to achieve with a good tune you will get around 600hp on pump fuel with the 2530's

[Guest Nismo_Freak]

Figured since the 2530s can flow around 320 ps each I would get around there. However I was more or less wanting to know what I can acchieve on stock turbos. Also what kind of boost limits I would see with the stock fuel system (w/ 255 lph fuel pump) and stock turbos.

Up to 600hp twin plate clutch, 600hp+ tripple plate!

[Guest Nismo_Freak]

alrighty... now... can someone tell me what I would putout with 14psi on stock turbos with those mods? lol...

[Guest Nismo_Freak]

Also pump fuel here is some crap gas still... its 93 octane :eek:

[kabab]

I think the most you can get out of stock turbo's is 400hp'ish don't quote me on this..

As for your fuel just because its says its 93 octane doesn't mean its worse then ours, in the states they use another method to determin the octane rating so your 93 octane is probably better then our 98 octane stuff.

[Guest Nismo_Freak]

Dunno... probably the same? WRXs get away with 14 psi on this "93". One of our gas stations underrates their gas... its 93 octane via label but it sure smells more like race gas than pump gas. It hasnt been tested but word is these stations have around 95-97 octane instead of 93 octane. I dunno, it doesnt seem logical why they would put higher quality, and more expensive gas and sell it as 93.

[Guest Nismo_Freak]

BTW... we use the CLC method to determine gas octane.

Volkswagon's old manuals (late 80s) said that their vehicle demanded 91 RON or 87 US Octane. They later mentioned that 95 RON is equivilant to 91 US Octane. So by this method 93 is 97 RON fuel.

who cares what number its going to put out. Just build it and see, you cant do any more than that, and no-one can tell you what its going to make either.

Before I go and spend 10K US ... I wanna know what it will put out, ball parked at least. Im more or less trying to figure out what the motor will output at safe boost and what safe boost is. Also general output numbers work well for tuning. If I get the car up there and make 100 hp short of what alot of other people are getting then I know there is something wrong with the motor and I need to find out what it is.

From memory I read somewhere that the stock turbos are good for 240-250rwkw.

also have to remember that there may be a difference in what a particular aussie dyno reads as opposed to a particular US dyno.
