Redtop Inlet Cam In A Silver Top Rb20det

[Aaron BNR32 GTS-T]

hey just wondering if anyone is familiar with this mod.

i got a redtop inlet cam that im going to put into my rb20det silver top.

can anyone enlighten me in what things i need to do?

the specs i have found are:

RB20DET Red top Camshaft duration 248°inlet, lift 7.8mm inlet, 240°exhaust, lift 7.8mm exhaust

RB20DET Silver Top Camshaft duration 240°inlet, lift 7.3mm inlet (also found it said it had 7.8mm lintake lift somewhere), 240°exhaust, lift 7.8mm exhaust

i know the RPM at which peak horsepower occurs is typically increased as duration increases at the expense of lower rpm efficiency (torque)

can someone please confirm these are correct and what i have to do e.g. adjustable cam gears to get the overlap right etc.

i am going to get the car tuned and dyno'd when i get all my things together for the performance side of things

cheers for the help
