I was considering doing a RB30 bottom end make the GTR 3L tt, but every1 said to much work, what yas all reckon?

Head is repairable.

Quoted $800.

Really need new block, turbos highflowed and head repaired. Most of the prices ive seen for this are more expensive then new engine, but i was very keen on doing the 3L convestion just to do sumthing different and working on the car for next 6months.

Every1 talked me out of it so far......how hard is it to do?

I say rebuild will be cheaper than 7k anyway - plus with forgies!

Nah, it'll be $7k minimum with forgies + head rebuild + turbos.

exhale 32, 26 head on a rb30 is a bit mismatched. The flow of the head is more suited for high revs, and the rb30 bottom end is never going to do that with a 7000rpm redline. Not without a new crank girdle and/or billet crank anyway.

By mismatched I mean a decent rb25 head will actually give more power at part throttle than a rb26 head. The rb26 head only really comes into its own at full throttle (larger valves) and high revs (solid valve train).

Still, if you want to go for it, just find someone willing to build it. It is a bit of a hassel though, with the drilling of larger 12mm head bolt holes in the block, tensioner positioning and the extra 38mm on block height. This is all imho :P

GOT BOOST I havent seen my dad in ages, ill ask him tonight what he's heard.

Do you think it'll be possible to have the whole engine completed with forgies and high flowed turbos done and installed for 7k?

What i need is.

1. Head rebuilt or new 1

2. New block

3. High flow turbos

What kinda price am i looking at just estimating.

Cause it might be cheaper just to buy a whole new engine.

if your gonna be selling the car buy another engine complete with everything.(then dont let your mates drive it before you sell it) as for costing and rebuilt engine you'll have to speak to a workshop who specialises in building them.Or someone thats just had theirs done to the same extent.

Have a rebuilder RB26 engine here with head complete, block complete and intake.

No injectors or exhaust manifolds.

$3K and needs a freshen only but that will still set you back around $3-4K

Cheers

Ken

    • Have a vb in honour of the car comming back
    • 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.
