Sounds like a nice spec to get some good power. I would also look at the fuel pump and perhaps upgrade that as well.

With all that in place you should see around 550-600bhp at the fly. I wouldnt rev much past the 8000rpm limit as N1 oil pumps dont like high revs plus you are keeping std rods. Saying that, with good mapping the engine should last for quite a while but i would run a compression test every 4 or 5 months to ensure everything is fine.

I would also look at a sump extention with baffles.

320-350rwkw is pretty much what everyone else makes.... So you wont be much different.

Mainly dependant on what dyno you use than anything else.

So for the boost etc, talk to your tuner.

I hope you used decent rod bolts though

To be honest nismoid i didn't do the rebuild i bought the car with all that stuff and it was making 250awkw on 14psi so i don't really know what rod bolts ere used.

but the do usually upgrade them don't they, when they do the rebuild??

[dontfeelcold]

not always. it depends on the builder and the budget.

[Turbz_13]

sounds fairly similar to my rebuild i just recently had done. my cars making 239.8rwkw's on 14psi.

im running a haltech e11v2 with boost solonoid and 3bar map sensor.

r34 gtr turbos(non steal wheeled, hence only 14psi)

should make 400awkws with the correct bolt ons id say with ease(not talking bout my car). ie bigger turbos, injetors, fuel pump/s, decent ecu, cooler etc.

ill rephrase that, that bottom end should handle 400awkw's

400awkw? Thats a little bit of an ambitious figure dude

[benm]

Get a pair of Z32 AFM's and a bigger pair of turbo's, that engine should easily handle into the 400's.

With good reliable tuning, proper support systems, i agree. For how long is the real factor, determined by use, bearings etc. A dead injector, failed pump, faulty rod bolt will spoil your day regardless.

Nice build man, envious !!!!!

I wouldn't take any of those into consideration though because they could happen to any engine, standard or modified.

Anthony you finally brought a real car

Not without upgrading to a JUN oil pump and the like.

Yea finally but i have to change the clutch and after that i can really enjoy it.

By the way guy's the turbo's that i have on it are the bigger r34 n1's .6/.64 so how much power can those turbo's make??? also when should i see about 1 bar of boost with these turbo's

Cheers

The N1s are the Group A versions which is what I have running on my wagon. Your set up is quite similar apart from your lack of cams and wheels. I made 500.9rwhp or 373rwkw at 23psi. The motor will take more and the turbos have a bit left in them but for reliability 23psi would be up there as a max.

So is this the same turbo's that i have cause everyone's been telling me that it will make a max power of about 310 rwkw. is that true??

I know that my turbos are the N1 Group A, same AR's as what you have stated. The advice you have received is incorrect or there are different boost levels being quoted.

well as far as i know my turbos are the r34 N1's i don't know if there group A's

by the way what rpm do you reach say 1 bar of boost, and do you have any idea when you reached 1 bar without the cam's??

You might like a set of cams in that engine.

i would love a set of cams if some one can sponsor me but at the moment my cash flow will only allow cam gears

I did a full rebuild and upgraded the turbos, cams, wheels, injectors, afms, sump, pumps, ic, oil cooler everything all at the same time. 14psi is reached around 4600rpm with 23psi coming in around 5000 so its a bit of a light switch.
