Gtr Joey's R32 Gtr E-Flex, Twinscroll 83/75 Results

[GTR_JOEY]

Hi guys,

So after more then 2 years of research, saving cash and waiting for parts the R32 is finally at a stage where im happy to post the specs and results (i only say that as there is always more work to be done ). The final result is already posted in the 400rwkw thread (THANKS PIGGAZ!!! lol) but i know from replys in some threads and a few PMs ive received that there is a few people interested in knowing the specs of the build as there isnt alot of info on the Borg Warner turbos.

I bought the car about 3 years ago from another member. It was running a lazy 280rwkw on a pair of nismo GT lemans turbos with an Apexi fc and some nismo injectors, Everything else engine wise was stock apart from the upgraded clutch which was a Nismo copper mix single plate. One morning on start up i noticed the car was blowing alot of blue smoke ..NOT GOOD! that eventually developed into a miss fire and i had absolutly 0 compression in cylinder 6. Later on down the track we descovered that the fuel pump was receiveing only 9 Volts, probably cause of engine failure was a lean out.

So we pulled the engine out and stripped it down, as suspected, piston ring land failure. It was time to build a new engine.Originally i was going to build my old engine from the ground up, as everyone whos built a forged engine knows this gets very expensive very quickly. Luckly for me i cam across a engine for sale off another member that already had a full build close enough to the specs i was chasing.

After looking through the results of the Rb26 thread and talking to Yavus at Unigroup and Geoff at Full-Race i decided to try something a little bit different and opted to go for a high single turbo set-up with a Full Race manifold and a Borg Warner turbo. Yavuz didnt care what turbo i used, as long as it was big, and there was only one haha

The engine was bolted in and the car was sent off to Hax at Performance Exhaust where a 4inch dump pipe was made and the gates were plumbed in. The waste Gates were are real pain in the A$$ to plumb in but Hax did such a brilliant job. Here is some pics of his work.

Once the exhaust was all plumped in and the hot side plumbing to the intercooler was finished it was off to Unigroup

The engine was Built in Melbourne by Creatd Motorsports, specs are as followed:

Capacity 2.6L

R33 GTR crank

Tomei rods

CP pistons

Jun Oil pump

Standard water pump

Standard sump filled to 6L (Race pace sump to be installed soon!!)

Tomei type B cams

Breathers from sump to head (passenger side)

Tomei oil restrictor

Exhuast and Turbo

Full-Race twin scroll manifold

BW S300 83/75 .91 housing

4inch dump pipe

High flow cat

3.5inch exhaust after Cat

Twin Tial 38mm waste gates

Koyo 100mm intercooler

Electronics and ignition

Link G4 ECU

Apexi AVC-R Boost controller

Ross balancer and Crank trigger

Ethenol Sensor and digital readout screen

Split fire coil packs

After market Ignitor

New OEM coil pack loom

Copper plugs

Fuel system

Nismo intake Fuel pump

ALPHA OMEGA Billet steel CNC'd Surge tank

Twin Walbro 400LPH pumps in surge tank

Sard FPR

ID2000cc injectors

Twin entry fuel rail

Braided lines all round

Duel filters

Bit of info on the surge tank, This is the first one of these and i was very impressed with it. Here are some specs and pics

It was designed and built by Wing at Alpha Omego parts and services

You can put in any standard sized in-tank fuel pump from 1 to 4 pumps: Walbro 255s, Walbro 400s, Aeromotive stealth, Deatschwerks DW200 and DW300 etc. ive got a pair of Walbro 400s in my setup, but if i ever wanted to shoot for maaaaaasive power you can just drop in another pump or two, plumb it up and that’s that.

It’s got four 5mm electrical terminals sealed with ALPHA OMEGA custom Teflon fittings so you can run a straight or staged setup with relays and switches, and it also has provisions for a single or twin lift pumps and single or twin outlets - in any size up to ‘dash’ -16.

Ok so ive been driving the car around for a couple of thousand kms now and everything seems to be running quite well

The tune is a full E-flex tune done by the Boys at Unigroup Engineering

Needless to say Myself and the the unigroup Guys were all very impressed with the results of the big dirty plain bearing Borg Warner. Looks like the money for the twin scroll was well spent.

Cam timing was set up to bring it on nice and early and as per usual the Tune is nice and safe on both E85 all the way down to 98 PULP

The only difference in the two lines in the graph is that there was more boost added to the mid range for when i wanna bump up the power for the drag strip.

How does it drive on the street? Fu#king brilliant, throttle response is awsome and its starts pulling hard at around 4500. Really enjoying the ethenol, gets a bit of wheel spin in second in the dry .. havent run 98 yet but will be for the longer drives

Wanna Give a big thanks to:

Yavuz, Mark, Tyson and Zack at Unigroup engineering, and for all the extra hours you guys put in and for making this result as good as it could be

Wing at Alpha Omega for the brilliant job on the surge tank and helping to get that set up along with the new Brembo brake kit

Paul (Piggaz) and Stevo (N1GTR) for all the running around you guys have done to help me out while i was away at work

Hax at Performance exhaust for persisting with the exhuast set up to get it 100% (even though you hated the job) haha

Thanks for the post - missing the pics??

[GTR_JOEY]

Cheers mate... just edited them

[XKLABA]

nice, it's always good when a plan comes together and you get what you where hoping for congrats mate

how long till you take it for a run

[GTR_JOEY]

thanks mate, been driving it since the SAU NATS so not too long

really happy with it, but theres always problems that needed to be overcome in a build like this, it wasnt a smooth journey the whole way haha

also the ignitor is a Morris tech black box ignitor, great value for money!

[Marko R1]

2.6ltr build with nice power curve is good to see, Congrats

[Looney_Head]

awesome results, i have a question. what were your injector duty cycles on the E85?

i have the same turbo that will be going on a built rb30 but only have 1000cc injectors

[Sinista32]

Good stuff Joe, nice when things work out.

I wish I had of found you when taking pics of your GTR at the Nats for a chat mate.

But yeah - very nice and very good results.

[Manuel Kasko]

Amazing results and glad its up and running

Been stalking the 400 club thread and reading about the whole thing

[SiR_RB]

Sounds like a jet on boost I could hear it 5 cars behind me when we did the wedding

Love the car mate congrats

Haha. That intake noise note is very distinctive isn't it.

[Piggaz]

Because Joey said so...

On the dyno

Surge tank setup

[Shoota_77]

I believe vids are required to fully appreciate the powa!

Awesome results though, well done for being a bit different. That custom exhaust work is brilliant!

[Marko R1]

That snail looks massive...how does it compare to the t51r in terms of external dimensions?

What diameter is take intake pipe? Looks very nice

[Marko R1]

Agreed, we need vids...I wana hear this distinct intake sound?

[Piggaz]

I reckon the frame is larger than a T51. It's bloody huge.

[SS8_Gohan]

hate to sound like a broken record

E-Flex = caltex high % ethanol fuel

Flex-Fuel = ability to run mixture of pulp and E85

I'm assuming this is tuned on United E85 not Caltex E-Flex?

anyways, brilliant results for a 2.6!

It's a 4 inch inlet Marko.

Looney_Head, not sure what the injector cycle is.. i will find out this weekend when i put it on the dyno for the SAU Unigroup dyno day. Depends on your tuner but dare say if i had 1000s they wouldnt be big enough mate.

Ill try and get some videos of it on the dyno, the BW sounds bloody insane..I have some on my phone but it just gets too distorted and you cant really hear anythin.

Theres a couple of American Supras on Youtube running the same turbo if yas dont wanna wait for me to upload a video

Dan, your right mate i stuffed that up, its tuned on United E85 with an ethenol sensor so its a Flex-fuel.

Marko, the thing about the BW is that the frame is bloody massive, though the front wheel is only 60mm (from memory) so it looks alot bigger then what it really is. One thing to note is i had to cut a small portion out of the bonnet re inforcment so i could close the bonnet. This is due to a combination of the size of the turbo frame and how high the turbo sits on the Full-Race manifold .. no biggie, nothing a die grinder cant fix!

Also forgot to mention im running Tomei cam gears,

and i forgot to give a Shout out to Geoff at Full-Race for answering any of the questions i had and reply back to quickly
