just thought i'd ask if anyone has tried this.

Seems that the CA18 is quite a bullet proof engine and that this would be an easy way of boosting the capacity. I have a friend who had a CA18DET rebuilt which is putting out an easy 200kw at the wheels on around 15 psi on a motor built to take 30 psi and he mentioned this as an option, unfortunately he found out about ca20 after he started his rebuild.

I looked at this option when i was building my ca for my 1200ute. The oil pump drive on the crank is much smaller on the ca20 mayb could be fixed with something like a drive collar similar to the 32gtr upgrade. And also from memory the snout which the balancer is fix to is much small also. Another option was to put a tomei crank in which wasnt to badly priced $2400 through greenline. Ca's are very under rated engines we have made 415rwhp 26psi on bp ultimate.

CA's sure are underated...

I had a CA18 silvia, 180kms motor, never been rebuilt, still had 100km jap service stick on the moror. Just bolt ons.. Disco potato .64 3inch full zaust power fc, fmic etc the lot (with an unopened motor and no aftermarket cams)

And i was running 22psi on it all day everyday for 200kw for over a year before i decided to buy a gtr... its still going.. would be close to two years now.

It even saw 25psi on a few spikefull occasions. No car could beat it off the line interms of acceleration.

I don't know what people do to blow them @ 1bar or 1.2bar but my stock ca was a bullet.

I wouldnt forge a CA just for 200kw, but then again maybe i was just lucky with it.

It never lost to any SR.

      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.
