so i finally have 300 horsies running around in my engine bay!!! it was a fight getting them all in there and quite expensive but i made it...

now i need the oil cooler on and then time to hit oran park again!

to get these horsies in there i used:

HKS GT-RS turbo kit

Just Jap FMIC

Xforce 3'5" turboback exhaust

Apexi Power FC with Boost Control Kit

Apexi Power intake

Splitfire Coil Packs

forgot a couple of things:

Nismo 555cc injectors

boost is 1bar...

guys who r getting more for the same or similar setup... any tips for tuning or adjustment?

did you have to tighten the wastegate?

if he is running 300rwhp with a gt-rs i would say he is running about 12-14psi. as they normally make 350rwhp @ 16psi (generally not always, depends on the condition of ur engine etc )

I'm on 255rwkw with the GT-RS @1.1 bar.

Is that 300rwhp or 300hp at the engine? i'm guessing if you say its in your engine bay then its at the engine? Because if thats the case it seems alittle low for a GT-RS on a rb25...i was just wondering and not having a go at you...

1 bar is just creeping up into that turbo's efficiency range...whack it up to 1.2-1.3 and she'll come alive...tightening the wastegate should not have an effect on peak power as you max boost should be controlled by the PFC boost controller...however...there should be enough preload on the actuator to hold the wastegate flap firmly shut...

    • Sadly I can confirm if you are actually seeking to drift, you will quite easily spin up one wheel. Even if you're going in a straight line. I am not entirely sure of the metrics/terminology here but there's only a certain amount that the helical will actually spin both wheels. I've seen it on video with my own car where two lines of smoke switch over to just one after you really get in to it. Unlike with a clutch diff where you can keep your foot planted until the car regains grip, in my experience with the helical you want to be utilizing traction control allowing LIMITED slip or lifting (partially) when you start to spin up both tyres with a Nissan helical. Which makes them pretty sub optimal for drifting duty. That said... this is probably a helical on numbers alone. Just put the Kazz in
    • Let's just fix the problem by f**king the rest of the gearbox.
    • Unlikely, as per Greg's post. This is not helical diff behaviour unless one wheel is up off the ground. Shimming what? You don't "shim" a mechanical LSD. Probably not in the sense that you have heard of people "shimming" a diff. And the process that Nissan f**kwits call "shimming" a diff involves super-preloading a VLSD cartridge against the side of the diff to create a friction/wear point (in a place that it wasn't supposed to have one) to make the sloppy, useless, viscous diff into a hybrid viscous/mech abortion. In case it isn't clear, I consider the process to be stupid. Nike.
    • How much does the shifter move when the car is in gear with the engine off? If it is more than about 1cm you need to replace your shifter bush. Your shifts will just get crunchier, not faster, with a short shifter unless you also rebuild the whole box
    • I should video mine, will prob do it tomorrow    Between 1st and 3rd, you could fit another two gears. That is how loose and wobbly it is   horrible:(
