Rb20de Cams Into Rb20det?

[VLT020]

hey,

ive been told by few people that there are gains in putting rb20de cams into rb20det motors.

just wondering if anyone has done this or knows of it been done.

any info would be great

im not sure why you would want to do this as they have shorter duration.....

check out tomei's website in teh cam section for the specs, if anything grab a set of redtop cams they are longer (duration) than the silver top rb20det.

*edit*

the intake cam on the r31 rb20det had 8* more duration than the silvertop so it would a tiny upgrade over stock.

I'm sure I have read somewhere that turbos do better with shorter duration than an equivalent N/A. It's something to do with the speed, not the volume, of exhaust gas turning the turbine.

But it's also all the other parameters of camshafts - lobe centre, lobe separation, lift, overlap - that determine the overall result of a camshaft change.
