😂 Looked like the engine blew up ! Without the right restrictors in the block, u can run the engine the whole day under 6000rpm, but go to 7000rpm and the tappet covers fill up by the time u reach 4th gear, and then oil out the breather pipe. That was the only thing on the first RB30DET that wasnt right.
Is this the na vvt head you bought from skylow?

Yes, now ported with turbo valve springs.
Its coming nicely together there RB25SX, you must be itching to get that thing going 😈 😈
Another milestone about to happen !
This is going to be good .
Can't wait !
Recieved the last of the engine parts. Forged rods from Spool in Auz. Main reason for the rods are not only strenth but less weight than std. If all goes well, should start assembling end of the week.
For those who didnt know, RB30's have a very good rod to stroke ratio of 1.76/1 compared to RB25/26, just means less of an angle during the up-down stroke and less sideways wear on the sleave and piston. The long stroke results in high piston speed compared to RB25, but lighter, stronger forged pistons and rods still allows reliable high rpm (up to 9000rpm used by RIPS in New zealand on std crank and block) I wont need to go that high. 😉

Awesome stuff 😀
Sorry for the off topic chat RB25SX 😳
RB30 std. crank ready, polished, balanced and wide oil pump drive fitted.
Cyl head cleaned, rebuilt, ported, skimmed and reshape combustion chambers with squish pads removed. Squish pads are only effective if the piston top can come to with in 0.5mm of the head, otherwise it can cause more damage than good(detonation). When removed it also "unshrouds" the valves for better flow. With the pistons i use and comp ratio i want, i would not have been able to get effective squish from the head, so thought it would be better to remove them. Rudeboy, for one had good results with the same head mods. Also some oil gallery mods, to allow internal oil feed to VVT 😉
looking good - cant wait to go for a drive in this car...
same will be awesome!
haha nice stuff rudeboy - I dips shotgun in the evo! haha.
