Hi Everyone!

I recently purchased an R34 GT-R :laugh: having owned a R33 GTS-t before i always loved the skyline!

Im planning on modifying just about everything and looking to have a nice tuff streetable and semi trackable GT-R by the end of it.

The car is a 1999 R34 GT-R V-Spec in factory white purchased from a private sale (carsales.com.au) car is very clean apart from a couple of very very minor things which nobody else would care about but me (im very picky i guess) they are easy DIY fixes,

but im very happy with the car money well spent in my eyes.

The car has done about 100000kms, the stock cluster was replaced with a nismo cluster at 80000kms

Its mostly stock with a few tastefull mods:

  • Apexi Power FC D-Jetro
  • Apexi N1 Evolution catback exhaust
  • Apexi Super induction kit
  • HKS EVC boost controller
  • HKS turbo timer Type 1
  • Skylab TSC
  • Nismo 330f steering wheel with works bell boss and quick release
  • Nismo 320km/h cluster
  • Nismo multifunction display
  • Nismo super coppermix twin plate clutch and flywheel (im very impressed with this clutch, its very light and easy to use, you wouldnt even know it was a twin plate)
  • Nismo side skirts and rear pods
  • Nismo LED Tailights
  • Nismo braided brake lines
  • Project Mu slotted rotors and pads
  • BJ Union HID Lights
  • Ganador Mirrors
  • Tein Super Street Coilovers

and a few other bits and pieces not really worth mentioning.

focusing on one area at a time first things first...

Ive decided to build the engine straight up because im a little bored of the factory power, im looking for something responsive and streetable, but something that can be violent at the same time, and reliable ofcourse.

Most of these ideas came from friends who have done this before, this is my first build.

Ive chosen the RB30, then got talked into stroking it to a 3.2l for the extra torque and a T04Z for some response hopefully.

Some of the parts are as follows...

  • Prepped RB30 block
  • Prepped RB26 head
  • Nitto 3.2l Stroker Kit
  • Nitto oil pump
  • N1 water pump
  • Tomei Procams 280 degree 11.5 IN and EX
  • Tomei cam pulleys
  • Darton sleeves
  • Supertech valves, springs, etc
  • 6boost exhaust manifold
  • Hypertune intake manifold <---- Still to be orderd
  • Rips Crank Girdle
  • Garrett T04Z .82 rear
  • Turbosmart 50mm Progate
  • Extended Sump

Engine is on the build, so it shouldnt be too far away unless we run into problems (knowing my luck) :dry:

it will be a little while before the engine goes in becuase i still need fuel system, intercooler, and so on.

While the engine is out i want to repaint the engine bay and have all the wiring hidden so everything is nice and neat.

Heres some photos from carsales.com of the car just before it arrived

Ive had it for about 3 months now :D and im very pleased

Pretty dam huge cams for a stroker. Personally i'd be aiming for something more in the step 1+2 range, to keep the usable torque band as wide as possible. Ive not read anything about the Nitto 3.2 kits before either. It would be interesting to know what the bore and stroke are that they are using.

+1, going to be one mental build

wow thanks for the quick reply guys :thumbsup:

i was told originally nitto was making a 3.4l aswell but it was scrapped and they are now only offering the 3.2l so i went with that

as for the bore and stroke of the kit im not sure to be honest but ill find out for you

the cams where recomended buy my friends, if they arnt suitable then they can always be changed i dont mind, like i said its my first build, but with people like you guys throwing me hints im sure ill be pointed in the right direction, its still a while before its going to be ready, plus i havent got the rest of the things i need like fuel system and so on...

ive learnt that all this building and modding is VERY EXPENSIVE pinch.gif lol its cost me an arm and a leg to get to where i am but i dont mind its been a bit of a dream of mine i want to get it out of my system!

thanks again for the quick reply and ill try and keep this as up to date as possible!

bore is 86.5mm and the stroke is 91mm pretty sure

I just found the kit on the high octane site and it says 90mm stroke x 87mm bore to make 3.212cc. Rod ratio is 1.69:1 with a 6" rod. At 8000 RPM that makes your piston speeds peak at 38.8m/s and an accelerate rate from TDC/BDC of 40.2m/s^2.

I suspect the reason Nitto abandoned the 3.4 project would be that piston speeds get pretty crazy with the 95mm stroke (43m/s^2 acceleration rate). But more importantly there is less material overlap between the mains and big ends which reduces crankshaft flexing and whipping.

The only way to make a 3.4 crank that would be as strong as a 3.2 or even a stock RB30 crank is to increase the diameter of the mains bearings another 5mm or so and then aligh bore the block block to support larger main bearings from something like a BMW or Ford Clevland engine. Oh boy are you taking big dollers then though. If I had to guess, RIPS probably did something like this with their 3.3lt engine.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
