hey.

i have had my plenum on my RB20DET modified to relocate the throttle body from the side to the front.

at the front of the plenem there used to be the coolant lines goin to it and a few others.

now where should i hook up these coolant lines? should i block em off or put a T-piece and join the three together?

them vacum for the pressure reg i presume just get from anywhere on plenum.

the oil breather one is taken care of via catch can.

ive included a few pics of my setup and a standard so you know what im on about.

any help would be great.

cheers

That 10mm bolt that isnt there anymore is used to bleed the air out of the cooling system, maybe making up a....... um how do i explain it..... water tank that the lines will run into with a cap or bleeder on top so you can still bleed the system might be the best bet.

im gussing the RB20 has the water feed through the throttle body like the R33 .. what did they do with that?

i have the plazmaman planum and there is no bleed for the radiator... just have to be patient on bleeding the radiator manualy via the turbo water feed, or the rad cap.

don't forget if you block that water line off where it goes too after the throttlebody!!! it feeds your turbo!

id personally block the throttlebody off and run a fresh line to the turbo. Im getting a header tank and doing away with the bleed on mine.

You sure about this one ?? I have the line blocked off for my throttle body and the turbo still gets water. Doesnt the turbo line feed from the back of the plenum ?? and then back into the side of the block ?

      Original window sticker?

      By Celticsfan03 · Posted

      Hey everyone. Is there a way I can get the original window sticker (maroney label) for my 1995 R33 GTST? I doubt I’ll be able to ever get it but it’s worth a shot to ask

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
