Nzmo32 R32 Gtr Build Up.

[Evocoop]

Hi folks. Just been reading through a couple of you guy's build up threads and learning some valuable information and thought you might be interested in my build. I have been slowly trying to build basicly stock R32 GT-R into a bit of a circuit/hillclimb car over the last 12 months since I destroyed the motor from an oil surge at our local hill climb here in Townsville. When it's done I'm really keen to head south for Superlap as it looks fantastic and our pissy little track dosen't really offer the sort of excitement I'm after.

I bought it with a set of 2560 garretts, Power FC, injectors, Greddy pipe kit, Twin plate Direct Clutch, HKS manifolds and dumps and a big exhaust. Good enough for a 11.6 at 117mph on streeters. But after I found the #6 rod had pounded its way into the bellhousing and the piston up side down in the bore I thought it was time to build something a little more worth while.

So heres some picks and a few details about what I've been up to over the last 14 months or so.

This is how it looked after owning it a few months. Nothing special but tidy.

Then I broke it.......

So I started building. Bought a new N1 block, new crank(grub screwed and balanced), Eagle rods, Cp pistons, ACL bearings and Arp studs.

Then I got a head and filled it with Tomei Pro cams, buckets, guides, type b valve springs and new Nissan Valves and stem seals. I put a tomei 1.2mm head gasket in aswell as got some port work carried out. Had the exhaust opened up a bit and the inlets cleaned up.

Then I bought some new turbos cause some of the old motor had gone through the 2560s and damaged the wheels. I settled on HKS GTRS turbines and also picked up some Trust dump pipes that I though looked the goods. Still using the HKs manifolds off the old motor but port matched them.

After some major deliberation and saving some more dollars I decided that all the band aid fixes for the Rb26 oiling system were not gonna put my mind at rest with a now quite expensive long motor so I bit the bullet and bought a dry sump kit. Now it's all just sitting in the corner till the car is ready to recive it's new motor.

I bought a second hand ARC twin entry intercooler from an R34 and mounted that up, but as it turned out I had to make all new mounts for it anyway cause when i bought the new PWR radiator to fit in where the AC condensor used to be I had to change every thing anyway. Still haven't made the radiator support panel yet but it's on the to do list. I have the template cut out and the ally sheet. Just gotta find the time.

I put a roll cage in to. It's Made from CDS mild and is basicly a 6 point tagged to the pillers, side intrusion bars, roof bar, windscreen bar, harness bar, cross and diagonals and one under the dash. Back seats are gone and replaced with a 1.6mm folded parcel shelf and rear fire wall and sealled up as per Cams spec for the fuel system in the boot which at this point consists of a SX 1000hp pump and 4.2ltr surge tank. The fuel system in the pic is just mocked up and still needs work fo fit properly.

I have changed to a FC D-jetro for management and mounted all the map sensors on the plenum.

But yeah. So thats about where it's all up to. There area heap of other little details that are going on but this is pretty much the sumerised version to get this thread started.

So the Goal here for me is to get some feedback to see if I'm on the right track as there is no precedent in North Queensland that I know of as far as GTRs are concerned and any ideas or advice from the guys with the experience circuit racing GTRs will be golden. I've already had some help from some of you and that has been a tremendous help so I know there is a lot of experience and knowlage on this forum so please feel free bounce some ideas my way.

Cheers

Lookin good Coop...well done mate....keep the updates coming.

to get the GT-RS's to respond the exhaust ports should look something like this...

well done, looking fantastic.

Can't wait to see the results come in. Would be great if it could make it down to QR one weekend also!

Looks good!

More info on the dry sump kit please?

Definatly keep the bent rod, it would make a nice, but expensive paperweight - ive got 6 CP pistons doing the same thing

[Z1LLA]

Nice buildup mate, as the others have said keep the updates coming, its really interesting to follow this sort of thing (which I will probably end up having to as well at some stage when my standard motor expires)

Thanks. that looks like you've taken a fiar bit outta there. I wasn't too sure how far to go but if need be i can take some more out later. I wish i took a better pic of the ports now. As a guide i took the lump out from near the stud and left it about 2.5 mm smaller than a Tomei steel exhaust gasket. Then matched the manifold to the gasket. A shop up here told me that this step was needed to create a small vortex to help scavenge the exhaust gas. The shop specialises in NA pro stock drag motors so I'm not certain they are that cluded up on jap gear. Time will tell but. I have followed the progress on your 32 for a while since i found out you were running the GTRS turbos. Very impressive.

Thanks Michael. It is a plan to get down to QR for the time attack thing. I was a spectator a few months back the week after Jamboree. So defo Keen for that. Was talking to Cameron Dyal with the orange EVO 8 and he got me all keen.

The rod. Haha yeah i'll do something with it as a momento.

The dry sump Kit is just a basic Hi Octane kit consisting of a Barns pump, peterson tank and I think they get performance metalcraft to do the sump mods but not sure. I had the hi octane big sump and a tomei pump and an accusump to go on it but I changed my mind and sold the pump and sump and still need to sell the accusump if anyone's interested. Still in the box and never used.

What sort of Plenum is it?? Who makes it??

[Count Grantleyish]

The plenum is stock.

[Evocoop]

Yeah mate like Count Grantleyish said. It's a stocker with a pretty rough polish job.

I've bought a set of brand new 1000cc HKS injectors to fit in that rail but.

Great build coop All looks great, and that ARC cooler looks serious! I don't think I've seen one of theres like that before.

[Beer Baron]

very nice mate. love it. the dry sump kit is a good investment. a bit hard to swallow at first I imagine but the guys that are running them don't seem to be blowing up any motors...

[Angus Smart]

Great Buildup going on

I'm somewhere in the middle of doing one too. heading in a very similar direction to you, just doing the motor at the moment..

the drysump may very well be back on the cards too seems like a wise investment to save money by spending moar.

[Merli]

Very nice mate

Specs on the accusump that you're selling? What model is it? What does your "kit" come with?

Cheers

[Evocoop]

The accusump kit i have is a 3 quart accumulator, mounting clamps, electric solonoid, 20-25 psi pressure switch and a half inch check valve to go into the oil cooler line. They do make a universal install kit but you can make that yourself easy with a few speedflow fittings and some -10 braded line.

I paid over 700 bucks for what I have here back befor the exchange rate went to shitt so was chacin 650.

I have no pics just yet cause they're on my broken phone's memory card.

Yeah I'm really happy with it. Turns out it's already been modfied so the dry sump header tank can go behind the headlight. It's got a sharper bend on the outlet side to kick the pipe work back in tighter. Didn't expect that when i was offered it but I guess was just ment to be.

Thanks for the other kind comments. They keep me motivated. I just finished welding in the header tank mounts and cutting the holes for the pipe work.

These are my Work Emotions I'm using as track wheels. They've got some old RE55s rubber on but I've only used them once. My first time out with them I spilt the motor. They're only 17x9s but they were well priced when i picked them up. I actually lent them to my mates more than I've used them.

[Roy]

what sized tyre on the 17x9s? 245?

I Pretty much finished the mock up of where everything is gonna fit in the front half of the engine bay. Got the ali plate cut out for the radiator support panel and it's all rubber mounter with modified and flush mounted originals in the bottom and S15 rubbers on the top. Finished all the mounts for the dry sump header tank. They just need to be tidyed up a bit and gusseted. New mounts for the intercooler off the bumper reo are a little agricultural but that's the only place for them. Heres some pics.

Interesting place for the dry sump tank

Also, are you going to run a shroud on the radiator? Wouldve thought the unshrouded areas that arent drawn through by the fan will just be a waste of space. The factory wouldnt put it there for nothing, unless it only matters on cars that have to sit in traffic and dont get constant flow over the core

[N1GTR]

.....and im pretty sure i just answered my own question

Apparently It uses a V8 supercar core so there's probably more cooling power in the bit in front of the fan as there is in the whole of the original radiator.
