Thanks for the support of www.omegaxenon.com and his distributor in my country RPM Imports we are going to make a complete rebuild of our RB26 engine..... specs are :

WISECO pistons std

ARGO rods

ACL RACE bearings

ARP bolts

GREEDY head gasket

ATI s pulley

RC 1200cc injectors

GREEDY valves springs

FERREA Ti retainers and locks

FERREA +1mm valves

NISSAN complete gasket set

We will keep using the 264/9.1 Greedy cams, Jun oil pump, powerFC and BorgWarner 72mm turbo.

We our stock rods and pistons we manage to produce 640whp (4 wheels) @ 29lbs and 8,000rpm.....

how much do you think we could obtain now ?

Same turbo, cams etc...the only thing i can see thats going to produce more power is a fresher engine and the valve upgrade. The rest of the list is to make the engine more durable.

All the best with running new PB's with the new set-up.

Do you think that now we could increase the boost up to 40lbs and rev up to 9000 ?

what happened to the old engine?

float oem nissan valve 8500rpm all the way and brake one valve guide but everything else keep in excellent condition. I hope that now we could rev up to 9,000 because the dyno curve shows more hp on higher rpm.

I've got a broken valve guide on an RB26 head too. Which cylinder as it? Mine was cylinder, inlet valve, the last one out of the two.

Are the RC injectors genuine 1200cc in flow? I was looking at gettin them but I did hear reviews that RC Injectors are faulty, high flow injectors that dont seem to work all the time and dont flow their rated amounts + you get a mixed bag of injectors with all different rates from 600-1400cc when you order.

If you can up the boost then you will make more power. IF your peak power is at 8000 - revvin to 9000 is not going to net you more power obviously.

If anything you may be able to make peak power sooner and thus decrease your max RPM.

yes, same inlet valve. :P

RC injectors are fine a lot 2JZ with over 1000whp with no problem from my reading.

the Borg Warner 72 turbo is more efficient at 35psi than 29psi.

anyway we know that 640whp @ 29psi it was not correct we´ve using old stock coils and always an small missfire. now we have updrage coils also.

to DiRTgarage

a) how much is a decent whp on a single 72mm turbo with a 2,600cc engine at 29psi ?

b) do you think it´s crazy up the boost to 40psi ?

    • 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.

    • Unsolicited advice? Keep the engine as close to stock as you can. Nothing wrong with adding some boost and making a little more power, but given where you are, you really don't want to try to make it into a monster. I can't imagine the roads are up to it, and the lack of locla support when it grenades will be a ball ache. FWIW, If there is a dyno around that you can access, then brand new injectors are a good idea, which will lead you to (at least) putting a Nistune in it, which will allow you to put an R35 AFM on it, all of which will make it possible to make it much much nicer to drive and live with.
