power outputs for modded rb20det's??

[Chris32]

Running std hydraulic lifters with GTR Valve springs and cams...only changing the valve springs as my engine has done 170,00kms so probably well past their best.

Good quesiton about the cam differences R32 to R33 etc. Could be the different turbos and tuning that increased the torque more then a mechanical change in the engine...i think the cams im getting are off an R32 GTR

Is there any differance in the valve springs? I am most probably going to do all my mods on another motor I have bought, and then swap the newer motor in, so if there is a advantage in swapping springs I might do that as well

The cam differance question I posed is a interesting one, I wouldn't be surprised if each model is slightly differant, due to each model having to meet stricter emmissions laws etc. Or it could be just differant tuning? Who knows, but it would be good to compare each model cam side by side to see if there was any huge differances

Im not sure of a difference in the valve springs, im not using them expecting increased performance over RB20DET springs, im using them because they are newer, therefore likely to perform better.

If i was building up an engine i woudl definitley consider new valve springs, new, not necessarily aftermarket performance springs just new.

Ok, I'm not building a engine as such, just looking to improve a motor I have bought, so the cams will hopefully be going in, but not sure about newer springs. The motor has around 50,000 on it, so the springs should still be in good condition (hopefully)

If I can get a set of springs with some cams - it will be a bonus, if not, cams by themselves will do for me

Aftermarket (new) valve springs are cheaper than buying standard (new) valve springs.

The R32 RB25DE NA will bolt up nicely to all the stock wiring in a R32.

Slap a set of forgy's in it bolt on all the RB20DET gear and no one would know.

Thats if you don't want to go the RB30DET route.
