My R33 Gtst (weekend/trackday)


Recommended Posts

Greetings from Holland.

Im new here but I wanted to share my car project with you guys :)

Registered some time ago and came here because of the massive BW EFR tread haha.

Been reading a lot and now I think its time for my project tread to be put on here.

There is no real deadline since im pretty bussy with work the last year so there is no real progress made since half a year ago only scavenging for parts.

So here's the story.

3 year ago I purchased a crappy r33 gts-t.
Engine needed to be swapped because the other one was crappy.(died after the first month and hardly driven it)


Some pictures of the car and blow and other engine :)

So I bought a rb25 with forged internals.

cp pistons/eagle rods/arp studs/acl bearings/steal headgasket.

Did some driving around for almost 2 years without any real mods and then after 2 years the clutch was beginning to slip.

After some thinking and going to events where they had track days and time attack I made the choice to build myself a fast weekend/trackday car.

Befor I put the car away for a while so I could save up for some money for the parts I went for a engine checkup and with that checkup it came clear that it was better to rebuild the engine.

Compression and leaktest shown that it would be better to do so and there were some marks in some of the cilinder walls so there goes Bore 87mm :P,

So I brought the car to a mate's race teams warehouse where he is head mechanic and left it there for a while so I could save up and work on it when we had the chance to.

The main thing about this project is that I want to do all the things myself that I am capable of, and if not my mate will be standing by.

We cant do everything ourselfs but what we can do will ultimatly save a lot of money.

So when im not that bussy at work we will yank the engine out and start rebuilding.
Car will be build for street/circuit(trackdays)

Power goal 650hp and anything above will just make me happier :D

Speclist for engine how I see it(may change a little depending the wait of the parts)

RB26 crankshaft balanced
JE pistons 87mm bore (rb26)
Cometic head gasket (size ?? )
Eagle H beams
ACL bearings
Borg Warner EFR 8374 IWG
6boost manifold
3,5" exhaust system
Greddy intake
N1 waterpump
Nitto oil pump
Topfeed fuel rail
1000cc injectors (if e85 I need a bit bigger)
Fuel system still under advisement thinking about Holley dominator 1400 pump
modified oilpan
Xtreme clutch 230mm

Head
Supertech single springs
Camtech 268* 9mm
HKS exhaust gear
HKS belt
Custom rockerscovers with an10 fitings at the back and copied Mine baffle plates installed
Cilinderhead ported/polished

Ecu thinking about Link g4.


With the chassis, exterior and interior.
Still road legal

Chassis will be stripped down.
Rust will be cut out and welded
Rollcage (maybe bolt in)
Bodykit Vertex with rocket bunny v2 style fenders

Custom made rocket bunny style drift wing

Colors some mix of black and orange.

Cosmis wheels

JBT big brake set 355mm 6pot front and 355 4 pot rear.

Driftwork arm kit

Lots more that I cant think of anymore.

Pictures of taking out the engine

So this was one of the last steps till we both had no more time on our hands the last 6 or so months.

To busy with work and other stuff.

So on towards some of the nice parts I have been collecting for the build.

Here is the Nitto oil pump

So this is what I have up to today.

Yesterday the deal was made with garage7 for a set of Camtech rb25 vct cams 268/9mm which will be here in about 3 to 4 weeks.

When its a bit more quiet at work afther the summer is over I will go and take apart the engine and take the engine to a machine shop for the overbore and valve angle job of the head.

This is it for now.
Hope to keep you updated as much as possible.

Greetzz

Ps. please dont be a grammar nazi (I did my best with my English :P )

So I just received my cams and im not really happy.

I mailed with garage 7 for a set of cams with vct option and asked a couple of times about it and they confirmed that it was possible to get these.

When opening the box it became clear they were not vct able :(

As you can see both for adustable camgears.

Have mailed Evan @ Garage 7 already and hoping for a good solution because I just payed 180+ euro's import tax for these cams that are not right.

:(

Good news regarding the cams.
Camtech agnolished their mistake and is making an intake cam to send to me when its ready.

Good and fast service from Garage7 and camtech.

In 2 weeks im going to rip apart the block and hope to get it machined the same week (if possible)

So last week I got the VCT intake cam from Camtech :) this time it was the right one :D

Yesterday we disassembled the engine and messured the cilinders.

Cilinders were in very nice shape even the bearings looked perfect as did the pistons(apart from some carbon buildup)

But there was a feelable mark in 1 of the cilinders (that were seen on an engine check some time ago)

This was one of the reasons I wanted to freshen things up and bore 87 and oversized pistons.

Next week im am going to clean the block and measure for the right size of bearings for the rb26 crankshaft.

    • I've been running a 525 for years with the standard hat and FPR in the stagea (mine has a 32 gtr fuel rail and stagea and 32 hat and tank setup are the same) without an issue with base fuel pressure. You said when you disconnected the return it is OK, did you do so at the fuel rail or the fuel hat? Either way I'd be looking for blockages or in the case of the tank kinks in the lines downstream Note I did however have an issue with the current required for the 460 melting the fuel hat.
    • I'm trying to maintain stock appearance . Hicas is still installed (although has lockout kit) did you retain factory fuel pump hat? If so I assume you used a bulkhead fitting or similar ?  I was also trying to avoid a full re design as it was previously dynoed at 426kw atw with same setup but different pump. Changing return line would also mean having to change ethanol sensor and fpr and possibly fuel rail. Not chasing more power in any way just reliability of the setup 
    • I do think it's weird I had it for 2 weeks then the issue came up out of nowhere and progressively got worse. I would've imagined changing everything in the ignition system would've resolved any ignition related misfires but still has the high rpm and idle misfires that seem unchanged. I would've thought if it was fuel related it would happen all the time unless it's the pump losing pressure when it gets hot. If it was the ecu I would think it would do it all of the time.  Something I noticed when I had it all apart was a pretty decent coating of oil in the J pipe coming from the throttle body. The weird thing about that is the pcv that goes to the intake is blocked off. So that has me wondering if the oil is coming from the turbo because that's the only thing that could get oil in there. This thing does sound like it spools like a mofo like I'm a former dsm guy and the only stock turbo I've ever heard spool this loud (to only go up to about 5psi) is on a diesel truck. And the recirculated bov is really loud too I had a TurboXS RFL and this thing is just as loud and being so low on psi seems a little weird. I don't know if any of this is or isn't related but just trying to make sure I'm not leaving any potentially helpful information out. 
    • So latest update. I replaced the ignitor with a jspec unit from enjuku. It felt a lot better at first although it is a little bit cooler of a day than it has been. Warming up didn't have as much misfire sputtering as before. Went on a 10m test drive. Felt good, a lot stronger though I was taking it easy on the boost. On the return trip started getting the cutting out at higher rpm again and was getting worse the longer I was driving. Took it easy the rest of the way home. Before turning the car off was getting the normal idle sputtering I was getting before.  So where I'm at now, entire ignition system has been replaced with upgraded components. Plugs still gapped at .8mm. Removed the fuel cap in case it was building too much reverse pressure I'm the tank, didn't help at all. Now I'm still on the same tank of gas the fuel treatment was in, I'm thinking if I can run that out and then refill with fresh 93 maybe  the treatment is too concentrated in some areas but doesn't explain that it only does it once the car is warm. I'm leaning towards fuel pump or injectors but if the injector was clogging I don't think it would make it shut off like it has but then fire right back up like nothing happened. So my current guess would be the pump. Without a fuel pressure guage no way to test or check it while it's running.  So that's kind of where I'm at. Need to start testing fuel components and ecu/wiring but I'm at a loss of what's the next logical step and procedure for testing it. 
    • @niZmO_Man thanks for that info, lucky I bought the gktech ones 🤙.
