lol, just the 1? so many split blocks!!

If you chucked that type of money at an engine you would be trying to make it hang together wouldn't you? ;)

Not that op has specified power goals etc. As Darren said you are in 7 sec Territory to worry about it.

Besides the point, given it was probably a $50 block to start off with. The issue is that rare that it shouldn't even be a consideration for choosing between an rb30 compared to the rd28.

OP, there is a guy building up an rd28 block on these forums with a white r33 gts-t. Might be worth digging around and PM'ing him about the costs of machining the block.

The 50 dollar block is hardly the concerns though is it? More money is spent on oil.

Most common split in R30's is around the drivers side engine mount and down the center, bang smack between cyl 3 and 4 where the oil passages run and therefor the weakest part of the block, dont forget the front 4WD diff is there adding twist to that area.

Lots of RB30's also splitting the bores and having hairline cracks from the head studs to the bores too once pushed over 600Kw+ at all 4, much of that is in the tune too, there is only so much they can take reliably.

Grout filling is not so much for block strength but does help somewhat, more so to support the cylinder bores from flexing.

Lol 200..i really take photos of split blocks when i see them..its exciting stuff.

Apart from that if you name names with big workshops it starts a shitfight,that im not getting involved with..

Its a fact..rb30s split bores..always have..always will.my eyes have seen them

Some have more luck than others

Cheers

Out of interest to,the other day when i was talking to a guy up the pointy end of the rb field.
He was saying with manuals (2wd/slicks)they soon learned not to declutch the car and rev it and re clutch it... if it bogged in the 60ft as it cracked the blocks...

Not in Australia or NZ etc, but determinately in Europe where shipping a rb30 block is prohibitively expensive.

Topspeed in the Ukraine had an RD28 based RB26/30 combo in their 7 second R32 GTR, well at least until they put a VR38 in there LOL

      Garrett G Series

      Oof. One of my mates has an R34 GT-R that he initially was a "I want to go twins for response and convenience" on his stock 2.6 with Kelford 272 cams, but his friends are pests and were always in his ear about their place being in the bin.   Eventually one of the 2860-5s decided to add it's own input and force his hand, so he conceded and went for a Pulsar 6262G ("G35 900") with T4 0.85 hotside.    Here's an overlay of the results, same cams, same stock bottom end, same boost, same fuel, just from a pretty tidy 2860-5 install to a Pulsar turbo on a 6boost maniifold on BP98.   Worth mentioning here, it may seem like a dead horse thing but the dyno plot doesn't tell the story of how much better it is to drive - transient response has completely changed the car, he used to have flat foot shifting to stop it having to wind up again on gear changes even at >7000rpm... now it builds boost faster than that even short shifting.   It's 100% transformed the car before you even consider how much better it holds on: Pulsar and Garrett aren't the same, but from our experience if you're just looking for a better drive and the ability to make the same or more power I think the divided G30 770 would probably be the smallest I'd go to.

      Sweet, yeah hoping stock gears will hold up. May use the transbrake feature on hill climb starts so that will test it.

      Been down in Tassie for 2 weeks (a cruise, not a race for once) but spent a little time on her when I got back. I worked out the injector settings in the PowerFC were not correct for nismo 555s, set those to 66% +10ms and added a little air at closed throttle, set the timing (approximately, because it has some weird non 15o cells around idle) and now she starts and idles properly. She purrs like a kitten (ignore the co2 alarm in the background, I did  ) 20250518_171052.mp4 Next step, off for run-in, tuning and alignment!
