Need more info to be able to give you a better answer but...

I have seen stock RB25DET's push over 300kw at the wheels, but there are so many variables that you cant account for when extracting big power from an internally stock motor...

Your mate might get a solid run for a while with big power, or he might have to re-build it after it blows a hole in a piston... It depends on how healthy the engine is to start with.

Most of his reliability will come from a really good tune (assuming he is using high quality parts and lubricants aswell).

engine strength is not an issue. its tune quality and how close to the edge of detonation you want to run.

any engine, even a fully built engine with thousands spent will fail under prolonged detonation or preignition.

theres stock internalled engines pushing 300, 400, 500kw reliably

it all comes down to the tune and the quality of your supporting mods to ensure that the measured fuel is delivered and adequate cooling/lubrication is provided.

Yeh, to be on the safe side, I would suggest injectors, fuel reg and probly invest in a good fuel filtration system lol. Judging by the mods he wants a bit of power from it. There is plenty of places to get tunes here in Canberra. I believe ed from Autotech is a Haltech Rep, so probly see him. Or ESP I reckon would know their way around a Haltech and Trojan are Skyline specialists...

has a fuel reg and is getting a new fuel pump (something bigger and better then a gtr one) and some injectors. cheers stu and the tune is going to be done in nsw from someone i have never heard about lol mean while he then is going to take it to a place in sydney.

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
