When fitting N/A cams in a T5 is a case of just of lining up the timing marks or is it more involved ?

is there some gain to be had with n/a cams and would that be inlet, exhaust or both

Mainly inlet gains bit can fit both a few people have fitted th and found them good I did think about it but thats as far as I got

The only difference between the N/A cams and the T5 cams is the N/A cams opens the valve by 8.45mm and the T5 opens the valve by 7.95mm. As the N/A cams open the valve by 0.5mm more does this effect setting up the cam timing ?

Or youll loose power. Each cam has to be advanced and retarded to see gains. The advice i got was to get it 100% perfect or dont bother so i tried and think i did. I bought a cam timing tool from ipd usa £50 and thats got full instructions with it. But unless youre going for 400ish bhp i personaly cant see the point money and time for nothing. Rip kit and the Volvo 960 3" throttle body 18/19t exhaust + dp + rods with good map you WILL see around 320-340bhp.

[QUOTE=p fandango;597922]theirs 15degrees adjustment available on the standard pulleys[/QUOTE] well thats handy to know and will save extra expense, when I get round to building up a new motor for the T5-R, just in the planning stages a present
