He is a nice guy indeed!

That being said there are a lot of builds with -5's around the 360kW mark which is low considering with some careful head work and some more boost over 400kW is a reality. I do not see the point of 400kW (no offence to anyone) with GT-RS's (-10's) when it can be done with less turbo and better average power.

Planning to do something similar, aiming at 380-400awkw with -5's.

going to stay low mount twins with best response for maximum track pleasure/pulling of chicks.

i totally agree, however it depends on the capacity you are running

i have -10s on my rb26/30 & that is perfect! 405awkw @ 23psi

i also have -5s on my rb26 & that is perfect! 345kw @ 19psi, more boost should realise close to 400awkw

on standard internals? fark me.

Yeah stock unopened RB25 :)

What turbo at the moment? What boost level. Ur keen as... Love it

My Kando T67-25G 10cm running 1.75bar

Went 410.9kw at the hubs :)

Will post up graph tomorrow, pretty happy considering it's well over 30deg here today!

my 1st gtr gave me 6mths on a stock bottom end with 365awkw @ 23psi - wait for it...

What caused the failure?

It's probably only a matter of time but I don't drive it a lot and only use 1.3bar most of the time, which makes 350rwkw with correction off or 373rwkw with correction on

    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
