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 :)



Engine RIP :'(



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

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

(wings are rotted to the chassis :P will have to take a flex to get them off haha )





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


JBT big brake kit


6Boost manifold (real piece of work)





And last but not least the master piece.

Borg Warner EFR 8374 IWG next to the 7670 which i bought on impuls (it fits my nickname)





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.


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.

    • Hi Guys, my car issues seem to be going from bad to worse and I’m hoping someone can offer some advice. I’m a Brit and have asked for help on the Brit forums but they’re not as active as they once were.    To save my thumbs I’m just going to copy and paste my posts from the Brit forum. I hope this isn’t considered lazy or rude:- 1st post…… For a while now my dash warning lights on my R34 GTT have been coming on. All of the them. When it happens the car runs like a bag of s**t. I pull over. Turn the car off and back on and the problem goes away. It doesn’t happen again for ages and then all of a sudden the dash lights up and the car is struggling. This has become more and more frequent and it’s now pretty much undrivable. I need to sort this out but don’t know where to start looking. A quick search around the forums and I’m thinking maybe coil packs but I don’t want to just change parts for the hell of it. 2nd post…… Ok the latest in the saga……. I decided to replace the spark plugs and coil packs to eliminate them as the problem. I figured they were over 20 years old and could do with being replaced anyway. I’ve just been out to have a go at changing them but the car won’t start. It turns over fine but won’t fire. I had a replacement CAS here so have swapped that out but it still won’t fire. Pretty sure I’m getting fuel to the injectors as I can smell it! Any ideas? Should the coil pack harness have a constant 12v feed once the ignition is on? Can I test this just by putting a meter across the + and ground pins? Is there a relay or something that should give the harness power once the ignition is on? Any ideas/advice would be appreciated. I’m at my wits end. Don’t know where to start looking really???
    • Hi guys, im a Brit who’s been using this forum for a while. I’m after some help so thought I’d come on and introduce myself. my name is Paddy and I’m an old man (46)! I own an R34 GTT in cloud white. Had it a good few years and do enjoy driving it! Also enjoy the attention it gets.  for those of you who are interested I’ve posted a couple of pics. Not the best pics in the world and they seem to of come out worse than the originals but you get the picture   Will post my issues in the relevant forum. I hope you guys can offer some advice.    thanks. 
    • Started installing the meth kit last night, managed to get it mounted so I could still access the awd resevior. Battery is located on other side I figured this was a nice spot for it. Cheers mates.
    • I saw the E in the model number and stopped thinking. Might not be correct there.
    • As soon as I come on boost that rear housing area, along with all the stuff connected to it will get pretty toasty and I'm not the type to race for a whole 10s or so 😘
