RB26 cams fit RB20?

[zforce]

Hey guys,

Just a quick question, will RB26 cams fit into a RB20DET? More specifically HKS RB26 CAMS. Thanks.

[Spoolup]

yes, depending on the lift and duration

272 10mm lift in, 280 10mm lift exh. Will these work? Will they work with stock springs and lifters (as i am not sure if they are step 1,2 or 3)? Thanks.

no they will not work with stock springs, and you will need to have the head relieved to accomadate the increased lobe size...

let me know if you want to sell them though...

You will probably need to change over to RB26 lifters, and definately need different springs. Stock GT-R springs can only accomodate 9.5mm lift? Pretty big cams for a 2 liter, you'll need to change a host of other things as the power band will be above 9,000rpm - rods and pistons etc...

you cant use gtr lifters in rb20 or rb25
