R33 GTR Build

Update on the build

EFR installation finished off.

I decided to install a WMI kit in the car for the hell of it. Not really for added performance but more to keep intake temps down etc. I went with an AEM kit and added the fail safe flow gauge which monitors flow and alerts if it detects flow outside of an expected range, either high or low.

I made up a frame with some bar I had in the workshop.

Then mounted it to the rear strut brace

Final install came out neat enough for me.

The injection nozzle was installed in the factory IC pipe

I installed the flow gauge fail safe on a small carbon panel where the ash tray would sit. I wired the gauge 0-5v=V output into the link so we can see flow in the logs.

Car then went back on the dyno to get the EFR tuned.

Results were good, on wastegate spring (14.5 psi) the car made an extra 40KW over the old BW SXE setup. On high boost we made 403kw KW with 3 psi less boost, SXE was 380 on 22.5 psi. Response is a lot better and it drives nicer than the dyno graphs look so over all I am happy with the outcome. We didnt play around with cam gear timing in the end so that could always happen down the track. Remember this in on a completely internally stock 2.6 on 98.

Here is plot of response between the SXE8376 (Yellow and Green lines) and the EFR8374 (Pink and Blue lines).

Power plot

19.5 PSI - 403 KW
14.5 PSI - 346 KW

cheers

Good results did the trigger kit make a difference ?

ARP headstuds +1

Who are you going to get to tune it?

Yep head studs are a must, would like to do valve springs etc at the same time.

Its already tuned...

The trigger kit was installed at the same time as the Link G4+ so i dont have any data before then. Car was running a PFC with a tune when I got it. My tuner recommended a trigger kit from the get go so I just went with his recommendation.

The beauty of RBs, you can do the headstuds with the cams still in place! So do the studs now, do the valves/springs/stem seals another time!

Nice work with the wmi kit bracket.

So your injecting  the meth in to intake side of everything, why not spray it into the intake of the turbo?

Yes can be done that way also. From what I understand if you are using pre-turbo injection you will only use water, not a water/methanol mix. 

I may experiment with that setup in the future just for the hell of it.

Nope I’m going to run meth into the turbo, turbo has been rebuilt to make this happen and it’s a better way to decrease intake temps and increase power.

I wouldn’t use water on it’s own into the turbo as that’s asking for trouble down the road and deff not on a turbo that isn’t ready for it

Only just spotted this, nice build and some cool data - been looking at the 61mm SX-E thinking that it would be a nice match to an RB30, doesn't look bad.  Shame about the leak when it was tuned, it would obviously mess with the overlay a bit - both in terms of lag and power but clearly the EFR is a better turbo overall.

Out of curious, did you do a compression test before all this works?

Thanks

Been a while since I have updated this thread.

Car is running awesome and have not done any major mechanical stuff, just added a few visual things to the engine bay.

Decided to replace the factory strut brace. I found some carbon tube at work and with the help of one of the boys we machines up some end caps to suit.

Used epoxy to bond the oval carbon tube to the end caps

Had the strut mounts laser cut and then welded them together, pretty basic design.

Turned out OK.

Also made up a brake M/C stopper for no real reason other than I had a few hours free in the shed.

I decided to make up a new washer tank to replace the plastic tank I used originally.

Cracked out the tig and knocked this up

Test fit 

Painted and fitted

Also sourced a carbon cooling panel to tidy the front up a bit

Painted the EFR compressor housing gloss black to change the look a bit.

Changed the turbo intake to a carbon 4" tube and swapped out the red filter for black.

Bay as it is now

Some great upgrades! Awesome work on making them yourself!

Loving the stealth(ish) looking engine bay.

Thanks man, your project is looking awesome.

[Shoota_77]

I wish I'd made the same progress you have over a short time!

You've done the smart thing and chosen each mod and done it in a logical way.  Mine is a dogs breakfast with multiple different things all going on at the same time which leads to brain fade and minimal progress!

Keep it up, it really is a great looking and well sorted car that is no doubt an absolute pleasure to drive!

I decided to give the car a suspension refresh. It already has BC Gold coil overs but the rest was all OEM.

I ordered the full Hard Race arm kit for front and rear and a set of SuperPro front and rear sway bars.

Front: Adjustable upper control arm, Castor arm, 22mm Solid Sway Bar.
Rear: Adjustable lower control arm, Traction arm, Camber arm, 22mm Solid Sway Bar

One of the boys stopped in to give me a hand and we knocked out everything on a Saturday pretty easily.

Rear

Car is off for an alignment later this week so will see how it drives afterwards.
