R33 GTR Build

[AntsR33GTR]

Thought I would throw up a build of my R33 GTR. I managed to find a nice tidy example which had a few basic mods done. It had a set of Rota Grid 18x10 +15, and BC coil overs (which were wound down stupidly low). The exhaust was an aftermaket Y pipe and unbranded 3.5 system that was beaten to death thanks to the low ride height. Engine wise it is sock other than a set of Apexi filters and a Power FC. The car came with a dyno chart saying it made around 240KW on 12ish PSI.

I wanted to change a few things on the car to suit my taste and looks wise then chase a little more power. 

I started with the wheels as the Rotas were a bit tired and weren't for me. I ordered a set of Work D9Rs from Work NZ in gloss black, 18x10.5 +15.

A test fit showed fitment was solid which was good.

For tyres i went with Achilles 123S 265x35, the internet told me they were OK and it knows whats up.

I also raised the height up on the BCs as it was dumb low.

The exhaust that came with the car has seen much better days...

I fitted a new HKS 3.5" (sadly necking down to 3") cat back setup along with a new front pipe and made up a decat pipe with O2 bung for wideband.

Unfortunately the new front pipe (random China brand) sat pretty low and the exhaust was too quiet for my liking. So I made up a new straight through center pipe in 3.5" and modified the front pipe so that it sat higher for better clearance.

The OEM front lip had seen better days and needed some repairs. I opted to go with a Aliexpress carbon (one thin layer of carbon and some fiberglass behind it) front lip lovingly made by a 9 year old in Vietnam. I also ordered some other completely useless carbon bits while on the Ali website. The quality is not to bad as long as you are prepared to spend a bit of time to make things fit nicely. Not for everyone but suited the look I was after.

Removal of OEM lip

"Carbon" lip installed

Also got this "N1" bonnet lip for the sweet aero effects...

It needed quite a bit of work to get it to sit nice and flush but got there eventually.

Rear wing blade also went on, fit was surprisingly good.

Jsai Aero side skirt extensions, rear caps and "N1" front bumper ducts also. Painted up the end caps in the garage, they didnt come out to bad and the fit is good.

Side skirt extensions fitted.

Last was the installation of the carbon front bumper ducts. 

That finished off the exterior stuff and Im happy with how it looks. Next step is some work on the engine.

Simple, tidy and effective- loving it! Keep up the good work.

Couple of old Datsuns

Painted up engine covers as they were looking pretty shit.

Originally I was going stay with the twin setup and upgrade them but everyone seems to be going the single turbo route these days so decided to jump on that bandwagon. The plan is start with keeping the engine internals stock and just doing the basic external bits needed to make a nice semi quick street car. I wanted to ditch the old school power fc and went with a Link as I think they are pretty good value for money. The car will have some basic engine protection added around fuel pressure and oil pressure sensors along with AFR input via an innovate MTX-L wideband. Turbo wise I would love to have gone for a BW EFR 8374 as the results guys are getting on these turbos on stock 26s looks great. However dude to budget limitations I have decided to try the EFRs poor little brother, the BW SX-E 8376 with a .92A/R TS rear housing. These are a journal based turbo that incorporate some of the EFRs newer tech like the billet compressor wheel. Supra and LS guys in the states seem to like the BW SX-E stuff so thought I would give one a try.

Started to order a few parts to get started.

Borg Warner S300 SX-E 8376

Link G4+ and Siemens 875CC injectors

Sinco T4 TS Exhaust manifold

Turbosmart 60mm gate

NZEFI R35 Coil kit

Platinum Racing Crank Trigger kit

Franklin Engineering CAS Trigger Kit

Fuel rail and  Walbro 460

Nice work
In my opinion u need to get rid of the bonnet lip. They are supposed to go across all the way to the lights and doesn’t look right how it’s sitting

You sure about that? Most I have seen end 15mm or so before the edge of the bonnet...

 

[PranK]

Nope, its perfect.

Might be mistaking it for R32?

 

[UWISSH!]

[PranK]

Ok, so, they come in two variants.

Not enough for me to be removing it if it was mine.

Ok, lets leave the lip discussion now and leave this topic for the OP's GTR.

After sourcing most of the bits I needed it was time to start pulling the thing apart.

Platinum Crank Trigger kit fitted up. This requires a small notch to be made in the oil pump housing so the senor fits correctly.

Test fit clearance of crank gear to sensor

Sourced a set Tomei adjustable gears

They went on with new cam belt and w/pump etc.

Franklin Engineering CAS Trigger kit installed

Pulled out the old twin setup.

Sinco exhaust manifold installed, replaced all the exhaust studs with new nissan OEM at the same time.

Turbo test fit to get clocking roughly in the right spot. One downside to the BW SX-E stuff is they are big, the front housings are massive in comparison to the EFR range.

Intercooler and air filter piping mocked up. 

Then me and my good buddy X Ray knocked up dump and wastegate pipe. Dump is 4" merging back to 3.5" Wastgate is 2.5". We sure as hell are not winning any welding awards but it should hold together.

We tried to keep everything tucked as high as possible for clearance. 

X Ray had a random old power steering tank off some nissan which I modded to fit around turbo stuff.

Ended up fitting in pretty neatly.

Exhaust and wastegate fitted up.

Oil feed and drain completed.

Made up a SS heat shield to try and keep heat away from wiring etc. Dump pipe will be heat wrapped also.

Nice build write up and I'm glad you're not sparing any expenses on your GTR.

Cosmetically - you need to get rid of the old an dated orange side and front indicator housing for some clear Nismo ones. Ged a set of N1 carbon fiber two-piece wing blades for the rear and that'll set it off nicely. The rest it is nice as is in my opinion.

[AntsR33GTR]

I removed intake manifold so i could give it a tidy up and it would make life easier installing remote oil filter bracket and making fuel lines etc.

Decided to go with Aeromotive fuel pressure reg, added a pressure sensor so link can monitor things.

Nuke fuel filter

Made up some brackets to hole the reg and filter.

Fuel rail and injector installed and fuel lines made up

I sandblasted the inlet manifold as the original paint was a bit flakey. Looked at the idea of leaving it raw finish.

But in the end opted to repaint it satin black.

Made up a SS oil catch tank using -10AN fittings. Has some baffling and SS wool internally to try and catch as much oil and moisture mist as possible. It will be vented under the front drivers side guard. Found a cheap window washer tank that was the perfect size so made up a small bracket to attach it. Disclaimer: I am a shit welder so no need to remind me.

Test fit washer bottle.

Test fit in the car.

Grabbed a bunch more -10 AN fittings and hose.

 Painted tank satin black.

I removed the OEM push fit breather connectors going into the cam covers and installed a set of Franklin Engineering AN fitting adapters. These come with a tool to allow you to hammer them in nice and straight with out damaging the black finish which is cool.

Made up the breather hoses and reinstalled everything. Used some AN divider clamps to try and keep the lines tidy. I still have to make up the vent line that goes to the external filter.

You'll be happy with the turbo, I'm running one similar sized but low mounted with modded factory twin manifolds. That looks great as you have it.

[Dose Pipe Sutututu]

Twins in the bin!

Loving the build man, btw.. pop in some aftermarket head studs such as ARP2000 to preserve the OEM headgasket.

Hope so man, fingers crossed it is not a dog response wise.

Cheers bro, yea I would like to do that and some drop in cams also. Will see how the budget goes...
