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

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.

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.

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.

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

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

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.

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.

Cameron,

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”

Regards

Cameron

    • Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.
    • I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂
    • Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy
    • Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
    • @KinkstaahKrinkle paint the "silver" alloy, not the red filter frame Engine bay heat won't be a issue worth worrying about as the silver alloy blocks it off on 3 sides, as for the top, the bonnet seals most of it and the big OEM CAI intake snorkel is still fitted in its original position  I will head into Clark's Rubber when I have some time to grab some pinch weld to tidy up the alloy after I paint it As for performance, I honestly wasn't expecting any, the only reason I got it is because the intake noise sounds cool to my old ears when I'm feeding it the beans Sometimes it's the silly things you do in in life that gives the most fun, and I do love anything that makes cool car noises In other news: I survived 4 nights at sea with Jackie not throwing me over board, holidays are continuing now as we are currently chilling at the Beachcomber in Toukley, after taking the coast roads from Sydney in the MX5, top down all the way, Toukley is where I spent a good deal of my youth holidaying during the summer months, there's lots of reminiscing going on,  and lots of beaches and old houses to visit Next on the list is to head to Batemans Bay for a few days, but we will take the Commodore out to stretch its legs, then Commodore hasn't really moved for months
