Rb25 300Kw Cam Upgrade

If you couldn't see a coating then there was none.

Normal procedure is to use plenty of assembly lube, and that's about it. Make sure all the markers line up, and away you go.

When new, they come covered in a fine coating of a grease / oil to prevent corrosion. You should always wash them thoroughly before installing them.

theres supposed to be a protective coating on them that should be taken off, did anyone do that, i just dropped them in

I'm looking at putting these tomei cams in, iv got a spare head that I'm putting together new springs bit of a port and full clean of everything. I'm trying to find out if the tomei poncam still use vct or it is disconnected? what is the real loss if I disconnect the vct? iv already got a set of hks cam gears as well. I'm aiming for the 400kw range and as low boost as possible. has anyone used the camtech camshafts?

they retain the vct on rb25's, you'd loose alot of low rpm torque,spool etc without it

I think a kinda good comparison of the low down loss is best experienced driving a ~300kW GT-R vs. a ~300kW GTS-t... you will feel how gutless the GT-R when it is not on song where as the GTS-t with VCT will feel more alive and come onto boost earlier.

It's a misconception many have, thinking longer duration cams bring on boost sooner, I have no idea which keyboard warrior started that rumour but it seems many still think that is the case. I recently had a mate ask me if he should drop in 264 cams into his car to bring on the boost earlier, I honestly wanted to slap him.
