i was reading back through the history and wanted to make sure cause on nengen they dont list it as a kit just cams on there own.Nocturnal said:From what I know, you will need EVERYTHING.

BUT, it was made that you don't need head work and therefore can be installed without removing the head. At least that was what Abbey said before. Kick me if I am wrong.![]()
Whats the spec of your car?......The Great One said:sorry yes pro cam. at the moment ive got tomei poncams 260deg 9.15 lift standard valve springs. when it was on abbeys dyno pack they said the cams were at there limit on my spec so now ive got the engine out fitting forged pistons thought it was a good time to go to the next level of cams.

you should be able to get away with just fitting the cams straight in, but get the clearances re-checked to see if everythings sweet. if ur a little bit worried, get some heavy duty springs
Sorry, thought the solid lifter was the bucket.shanef said:I was referring to his comment of needing retainers & solid lifters. I've always been told to follow the guide of, lift 10.5mm or higher use heavy duty springs. But i suppose you have to factor in the 'what if' situation if u run 10.25mm lift with stock springs and some time down the track they sh!t themselves, could have been a bit easier to fit the heavy duties earlier.
The Tomei cams have a 30mm base circle vs the stock 32 mm base circle. This means you need to make up that extra 2mm somewhere. You could do it in the bucket, or in the shim. Tomei does it with a taller bucket. The buckets are direct acting aka solid. No real lifter in an RB head.Nocturnal said:Valve Spings, Retainer, Solid lifter.
