Gtt034 - The Second Time Around...

[Mitchee]

Some may recognise this car as 'Satanic', owned by an SAU regular Stan a few years ago. Stan bought the car bog stock from Northshore Prestige as a 1998 R34 GTT, Triptronic auto. Stan brought the car to me for regular servicing and mods, and we both learned alot about R34s and cars in general. The car was the basis for a lifelong friendship that was formed, and when the time came for Stan to move on from the car, it was only natural that I take ownership of the car and have my way with it.

A quick rundown of what was done to the car while in Stan's ownership.. The stock engine was modded with boltons, highflow, front mount, injectors, shift kit the usual. What is considered 'normal' these days was pretty new territory for R34 GTT's as they were still relatively expensive from dealerships and there wasnt very many on our shores. The stock motor popped with a dodgy tune, and we built a forged RB26/30 for her. GTK-650 turbo, FCON Vpro ecu, 500rwhp through the auto.

It was at this point I purchased the car from Stan, and started to make the car my 'own'. The starcorps were dropped, and I picked up a set of BBS LM rims. I always loved these rims and with a bit of guard work the 18x10's were slotted on.

My biggest problem with the car was the auto. The car never ran right with it, and ive never liked 'performance' auto's. Out came the auto and in its place an R33 5 speed was fitted. An xtreme cromoly flywheel and Jim Berry full monty clutch were installed at the same time. The FCON vPro was retuned for a safe 480rwhp on 20psi.

I cleaned up the interior, moving the defi's to the triple gauge and fitted an techedge wideband o2 which gave feedback to the vpro on air/fuel ratios. An eBoost 2 controlled boost and the exhaust had an apexi ecv installed to quieten it down when required. The car was lowered slightly and it was in this form that the car stayed for quite a while.

I took the car to some hillclimbs, drift days, and wakefield days and generally had a great time in the car. It performed flawlessly and was always rewarding to drive with the torque and power from the 26/30. I fitted a whiteline front swaybar and a Nismo GTPro diff after a trip to wakefield, and next time out managed a 1:09 on street tyres. Very happy for a large heavy car.

I took the car to plenty of meets and drove it every opportunity I got.

March of 2012 Powercruise Sydney rolled around and I managed to grab a garage entry which was awesome. Plenty of rain but still had a great time in the car. On the last day of powercruise, I went out for two sessions in a row then had to come to a stop, oil temps got a bit hot and when reversing back into the pit garage a rattle could be heard coming from the engine. At this point I was heart broken and knew what the noise was, as much as I didnt want to believe it. Oil pump was definitely gone, and something in the bottom end broken.

The car was towed home to my garage where it stayed untouched for a few months while a few things in my life changed, new job, moved house, turned 25. In the meantime I purchased an 250rwkw S13 silvia which kept me happy until I quickly grew bored of it.. Sold it off to a mate and began working on rebuilding the 34.

This is where the story pretty much begins! I tossed up my options for ages until I decided that the car deserved a full rebuild...

The front end was stripped and bits removed ready for disassembly..

Turbo out, the first work done,.

Gearbox out! It was f**ked after powercruise. Wouldnt stay in gears and was making some interesting noises. Too many 4th gear clutch kicks down the main straight I think. The JB clutch held up great

Engine starting to come out..

Engine out! Forklifts make light work of this job. Very lucky to have a spot in my dads workshop to keep the car!

Engine bay will be cleaned of most of this crap.. Its all old and dirty. New engine bay will hopefully be much cleaner and less cluttered..

The engine was found to have cracked the n1 oil pump drive gear, causing a loss of oil pressure and thus the f**ked big ends. It was at this point I decided that I would be building a new motor with a new turbo and fuel system setup, and I started collecting bits.

The engine was stripped down and parts put aside... I had quite a collection of bits at one stage..

[Mitchee]

The interior was removed and I went to town cleaning up the mess of wiring. The Defi's were going, and I am taking a 'less is more' approach with the interior. Anything that isnt compulsory is going. No excessive gauges or tackyness. Just oem+ styles.

A matching set of Nismo gauges were purchased and installed, and all wiring under the dash cleaned up.

I came across a great deal on some very low km used parts.. 6boost manifold, garret t04z, turbosmart progate and a haltech PS2000 with full loom.

A koyorad to keep things cool

New fuel system will be going in... Its comprised of an undercar surge tank with twin Bosch 044's, twin teflon braid 8an feeds to a 14mm fuel rail, turbosmart fpr2000, 6an teflon braid return line. 100 series braid between the tank and surge. All Aeroflow gear. The surgetank was sourced from Unique Metal Fabrications and the fab work is amazing.

Yep, she'll be running E85 hence the overkill fuel system. Ive not yet purchased injectors but will be going with a set of ID2000's.

[Mitchee]

I purchased a fresh S2 RB30 block which will be checked over, cleaned up and bored to 87mm. Tensioner relocated and the block drilled and tapped for ARP studs. The old block is on the floor...

Whilst the BBS LM have been great, they really are too aggressive for the car being 18x10+20 all around. So I purchased some staggered Enkei RPF1's in SBC colour.. 18x10+38 and 18x9+30.. These should be more suited to the GTT's guards. I'll have to run a 10mm spacer up front to clear the brakes, and possibly a 5mm spacer at the rear depending on tyre as the rim sits pretty close to the coilover..

Starting to collect some bits... here the gearbox has returned from being rebuilt with new syncros and sealed bearings.. Nismo engine mounts to go in too..

After some reasearch I decided that decent spark was needed. I ditched the twinpower/splitfire setup I had previously and purchased a set of LS2 coilpacks. These things pack a pretty big punch apparently.. Plugs were also sourced which ill have to wire in. I'll make up a bracket to run these 'coil near plug' using stock coilpack boots. Not sure if they will squeeze under the engine cover though.

So at this point I have a good fuel setup, a good hot-side setup, and the majority of the bits to give spark and control everything. All thats left is for the engine itself. After plenty of thinking I decided to bite the bullet and go all out on the motor. The torque increase from the RB25 to the RB30 was pretty amazing, so I thought it would be appropriate to go bigger again with a Spool RB34 kit. 94mm stroker crank, I beam rods and CP pistons.

Along with a box of goodies from Spool... Extended and baffled sump, ROSS balancer, full Cometic engine gasket kit, billet oil pump gears and a timing kit.

From Cartel a HEL braided brake & clutch line kit and some steel wheel nuts.

From Kudos motorsports a box of genuine Nissan stuff.. a new water pump, timing drive gear, exhaust manifold stud and nut kit, rocker cover bolt kit, belts, thermostat etc.

From Driftworks a thermostatic oil cooler kit..

Thats the majority of the bits ive collected so far for the build. The block is currently at the engine builders and assembly and machine work will begin early 2013.

The RB26 head will be copping Supertech 1mm oversize valves, dual valve springs, ti retainers and Tomei Procam 260 10.8mm cams. Along with a full port job by my engine builder. I dont have any pics of these parts yet as they are still in transit from the states.

All in all im really excited to get this build happening, and I have a feeling it will be completed in a few months time. Most probably a year since the day it broke.

I chose the RB34 kit after a lengthy discussion with my engine builder who has done a few Spool RB32's and Spool 2jz stroker kits and he is familiar with the bits. The extra torque and driveability from the 3.4 should be great. Im not expecting any specific power outputs, but a t04z on a 3.4 should be pretty responsive and make good power, especially on E85. Ive heard a lot of bashing from people about the Spool kits, especially the RB34, but I wont be wringing the neck of this thing 24/7, it will be a weekend car and to be honest, with the money im spending ill probably be too scared to drive the thing and somehow break something

I'll try to keep this thread updated with progress. Apologies if its a bit scattered, its hard remembering the last 3 years of owning this car, not to mention the flurry of activity over the last few months.

Cheers,

Mitch.

Looks great Mitch! Can't wait to see it all finished

[Adzmax]

Nice! First thing that comes to mind when I see that fuel setup though is it's so exposed.

[FST513]

Sweet build Mitch! Sounds promising and the parts you're collecting look pr0n. Might have to come visit when it's all getting put together for some pics before and after

Keep up the good work!

[On Edge]

Liking this!!! Will be following!!!!

[34GeeTeeTee]

I was wondering where this thing had got too Thats awesome.... I was only mentioning the car the other day when talking about engines for the 34

[Crazyduck]

Good thread, well written to. I'll be watching

[J34]

Havn't seen this car for ages. Good to see its still around.

[Mitchee]

Browsing Yahoo Japan last night I came across something that I had to google for a good hour in order to work out if it was the real deal or not.

4" HKS Ti-Racing catback exhaust to suite ER34. Very f**king rare, especially for an R34 GTT. Lets hope the seller hasnt f**ked up and its actually a BNR34 item

Stainless main pipe with a titanium rear muffler. Loud and obnoxious Got it for a relative steal considering its brand new, less than anything similar anyway.

Also pulled the old girl out of the factory for a quick scrub. The layer of dust and grime on her was pretty depressing. It was pretty motivating scrubbing back all the crap, really makes me want this back on the road sooner rather than later..

Before..

Dat dust.

Squeaky clean!

Also gave the engine bay another degrease and pressure wash..

Was pretty stoked when this lit up for the first time.

Once xmas is out of the way, plenty of progress will be made.

great build keep us updated

[dori34]

wow, i wondered where this beast disappeared to Mitch.

Sorry to hear about the bottom end, but good to see that you're rebuilding it for bigger and better things

can't wait to see the final completed product.

quick q, where did you get the gbox rebuilt and what was the cost of such work?

[Mitchee]

Cheers guys.

Dori, had the box rebuilt by Gearbox Logistics/Gearbox Solutions whatever they want to call themselves. While the turnaround was quick, and the picked up and delivered the box, the final charge was $2000 as the box was completely shagged. I knew this, but it still hurt knowing I could get a new one from Just Jap for $2700. Budget is just too tight.

They put sealed bearings throughout, replaced the gearset with one that was in better condition, new 1/2 and 2/3 syncros and replaced anything that looked worn with new bits. When the box returned to me the speed sensor was smashed off and it took a few weeks and a few phone calls to get them to send me a replacement. Im no longer interested in smashing through gears so hopefully this box can hold up with the torque. Its been in my mind that if the build streches out longer than expected and I have some spare cash i'll try and offload this if something stronger comes up for sale - say with a PAR gearset or something.

Anyways I made some progress today with my time off.

-6AN Feed and return lines from main tank to surge.

With some extra protection! The plastic cover that goes over this is off for the pic, once its on you really only see the lines in the wheel well for about 10cm before they disappear again. Should keep things nice and safe. If theres any damage to the loom tube ill fit some form of cover over the exposed section.

Here you can see where the lines drop down into the surge tank. The top left fitting is the return back to the main tank, and the feed from the main tank goes over the top of the surge to a 90 degree fitting on the rear. This means 'cool' fuel from the tank enters above where the twins draw from, and returns to the tank at the front. Im hoping this will keep a good flow of 'cool' fuel moving around the surge.

The top right fitting is the -6AN teflon return from the fuel rail, and of course the other two are the -8AN teflon feeds from each fuel pump.

Where the cable is coming out of the chassis rail, this is where ill run these final three hoses once i enlarge that hole, this will let them travel protected in the rail until they get to the front of the subframe where they'll exit and continue under the car where the standard fuel lines normally run.

Also you can see I've wired up the pumps, the wiring enters the boot through a rubber grommet normally used for the 4WD system in a GTR.

3 Relays triggered off the stock fuel pump feed. This gives full voltage to my in take pump, and the two 044's. I had two relays there already for the old setup with a single 044 and stock internal pump. I could have just run the 2nd pump in series but I decided to add another relay in case I want to switch the pumps off individually down the track. The old wiring was a bit of a mess and pretty ratty so it was nice to clean it up a bit.

And the final view of the boot before it will get covered up under trims. You can see the wiring for the twin pumps exiting on the right, the two braided hoses for the surge tank feed and return, and the relay setup. The boot is half black because there was some pretty bad fuel spillage from the old setup and everything was brown and gooey. A can of chassis black and we're good to go.
