Project 24

[RipNGrip]

Very nice read! Definately a tough r32... just sexy with show and go

[huddy]

looks hot - gl with the build up RB20 stroker respect

[murrayis]

Ok a quick update.

My head gasket finaly arrived from Tomei Custom one 83.5mm bore and 1.5mm thick.

Also New HKS oil cooler kit arrived in the same package.

Plenum is off being welded by a fellow names GT somewhere down gold coast way not sure who he is but came highly recommended.

So I am on the lookout for a rb20 billet fuel rail to suit 650cc Sard injectors, a 90mm billet throttle body and a nice thick alloy radiator.

Can anyone recommend any they have seen around, prefer one where the butterfly actually closers cleanly.

Cheers

Pics will be up soon

updates!!!!!!!!!!!

[murrayis]

An update you want, An update you shall get!

The engines together and sitting in my car port, working on gearbox, plenum, and exhaust manifold. I decided to give it a crack at making my own exhaust manifold before I bought a 6Boost job from Kyle.

Thanks Kyle for the flanges and a few pointer's, be nice its my first time TIG welding

Also have changed the turbo to a Garrett T04Z .84 rear split pulse, And installed new Tappered Lugs into the front and back of the block.

Waiting on All new sump, rear main seal and rocker cover bolts, should arrive next week.

[limpus]

Looks like its coming along nicely...can't wait to start mine...keep the updates coming...

[murrayis]

had a bit of spare time on the weekend during the cr4py wheather so polished the t04z comp housing

will probly get it proffesionly done, but was worth a go

[Oblivion]

wow t04z on rb24.....4500rpm spool maybe?

looking good though dude.

[murrayis]

Yea thought about the lag but its goign to rev to 9500rpm and is built for it. We are looking at running 29 - 30psi thought it on the dyno.

Anyone know any good machine shops in Western subs brisbane need to machine flat the exhaust manifold flange as its warped a bit from welding it.

[Sydneykid]

Watch out for the water pump, those universal ones can leak past the bolt from the slotted hole.

Thanks for the Gary, Have filled it up with silicone, Its a rb26 n1 Pump which looked the same as the one I got off my original rb20, but filled it up anyway as it looked a lil suspect.

Better post a vid with some noise of this motor when its done, is going to sound unreal.

So there is no bolt in the slotted hole, meaning no threaded hole in your RB20 block?

Cheers

Gary

[murrayis]

Gary,

There is now a bolt in that hole, when we put the pump on 5 mins before the photo we had lost the bolt so had to dig another one up so put it back in the hole.

hi,

new here,

doing an rb24 build myself over in ireland. much the same. did you get the uprated crank collar for the gtr crankshaft?

any updates as yet? are your cams rb20 or rb26 cams? also are you running tomei valve guides or larger ones?

keep up the good build

[murrayis]

Hi Reuben,

As far as i'm aware there is an updated crank collar on the crank shaft, But I am using a stock rb26 oil pump which will be heaps of oil flow for the rb20head.

My cams at TOMEI 270 IN & EX 9.25mm lift made for the rb20, I also paired them with TOMEI solid lifters and 2.6 Shims. As for the valve guides they are custom guides made by a local engine machine shop.

Cheers

Cameron,

You wouldn't happen to have a spec sheet for your pistons would you. I just got a set of custom pistons made by

JE and they came with a slight dome. They also seem to have move the compression height on mine down 3mm instead of 2.

They look a little different then any of the RB24 pistons I've seen before. At least if it's too much dome I can just have it shaved off.

[murrayis]

Mine are the complete oppostie to yours, inverted by 2mm so the domes resessed into the piston, not sure on the term.

I don't have the spec sheet any more sorry, And i can't get to the numberon the bottom of the piston to get the info again from ROSS.

But my oil ring is 4.25mm in height from memory. Sorry I can't be much assistance i will try get the info from my mechanic.

Ok i dug up an email from ROSS regarding the ring specs, I have emailed them to get a copy of the specs for the pistons.

RINGS:

Bore size is 3.270” Ring grooves are 1.2 mm, 1.5mm, 4.75mm radial depths are .134”, .144”, .180”
