Item: RB25DE block , crank and conrods Age: approx mid 1990s Condition: good Price: $ 100 the lot To Fit: (What car) any rb25 Location: Brisbane ( Coopers Plains ) Contact: ph 0413 546 380 Comments: PICK UP ONLY

Yes i built the rb25/30 , that i sold to Skit . I used the stock rb25de pistons on the rb30e rods . Edge of pistons were sitting 1.2 mm below top edge of block , that was supposed to be good for 10.5 -1 compression , but i have recalculated that because head gasket thickness wasnt allowed for before . Also the rb25de pistons sit above the edge of the block , i measured .5 mm , just as well the head gasket is around 1 mm thick . So i figure the compression to be around 9.8-1 I,m now building another rb25/30 , again using rb25de pistons on the rb30e rods . This time the block is being decked 1.2 mm to bring edge of pistons flush with top of block at tdc . I dont want the pistons sitting above the deck like they do in rb25de . i calculate the compression to be 11.0-1 with this set up .

are they from a turbo or non turbo ?

gday , does it come with a hand controller

I built this engine and ran it in my 86 r31 Skyline station wagon . With a 4.11 locked diff , 195,60x14 radials @ 20psi , i recorded a best 1/4 mile of 14.15 @ 97.6 mph at Willowbank dragstrip 16-8-2006 . Also at Lake Gairdner speed trials 2006 ,max speed of 141.18 mph ( 227kmh ) using 3.7 diif with .75 OD . ( had fuel starvation prob )

progress , umm xmas , too much work , relatives stayed for 2 weeks . how many more excuses am i allowed . Engine on one side of workshop , car on the other , looking at each other . Engine bay stripped ( 6 cyl engine and box sold ) , want to give engine bay a wash and paint , then start fitting . well run out of excuses so will get going again

Don here , not me , I,m doing a VH41DE into my r31 station wagon .

Gday , not here to brag about my car . Heres a few things i did to my RB30DE to get 14.1 @ 97 mph . For starters its in an r31 station wagon and only wieghs around 1300 kg . Get as much wieght out as possible , like spare tyres tool boxes , towbar if it has one . Am using a rb25de gearbox , so same ratios as yours . Diff has 4.11 pintara gears and a mini spool ( locker ) . Tyres were just 195 60 x 14 radials with 20 psi . Advanced the ignition timing approx 4 degrees , diconnect the vvt solenoid . Diconnect the exhaust at the end of the extractors ( you,ll love the noise too ). Hope this helps you go quicker .

Bottom end . I put in new big end bearings , rb25de pistons with new rings , replaced all gaskets and seals . Steel billet flywheel . I used a Bosch 040 in tank fuel pump .
