just wanted an opinion on how muck power my car will make, the rebulid has the following and i intend to put 600cc injectors and camgears to increase boost response. so please tell me your opinions and what would be a good rpm limit for the car as well as how much boost do you think i should run her on??

ACL Forged Pistons

Ported and polished head

Stock polished crank and rods

Bored and honed Block

N1 Oil pump

N1 Water pump

Tomei Oil Gallery restrictor

Gates timing belt

New engine gaskets all round

New Thermostat

New NGK spark plugs

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. :P

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??

Cheers

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

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 !!!!! :blink:

Anthony you finally brought a real car :rofl:

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??

Cheers

anthony

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.

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
