General Power Output - RB26


Recommended Posts

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!

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.

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.

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.

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.

    • Yeah kids certainly add a whole another dimension to your life.  Life ceases to be about you and more about them for a while!  And I wouldn't have it any other way.  I love watching them play sport and make new friends along the way. Wow, sounds like your mate is a good guy to know!!!  He's got some serious toys in the toy box!  Yes it would be lovely to be able to do stuff to your car without getting all tied up in boring shit like how to pay for it!!  I would describe my spending style as "aggressively spontaneous and logical but regrettable purchasing"....  That will hopefully make no sense at all which would be appropriate given that is how I buy stuff.  I'll decide at the drop of a hat that I'm buying something expensive, research the living shit out of it for 2 days straight then go out and buy it.  Then I'll have instant buyers remorse for 2 days which generally passes by the time it turns up on the front step!  If I'm feeling ballsy sometimes I'll tell my wife.  Other times it just makes its way silently passed the house and out the back to the shed, never to be spoken of again...
    • My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.
    • I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.
    • I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended
    • Yeah mate, no probs. Just swap the email addresses?
