Hey all,

 

Just wanting to nail down which crow valve springs to get.

I've got the mods for a 310-320ish rwkw tune, pw stage 2 cooler, piping kit, turbo side intake, larger fuel pump, etc etc.

I still need injectors which will probably be kpm 1000cc units, easily procured here in NZ and valve springs.

Mace Engineering NZ have a reasonable price on Crow items but not sure whether to get the 1808-24 with 95lbs seat and 195lb open and use stock retainers or the 105lb seat and 205lb open which appear to need crow retainers? Mace kit part # is SPG-613 for the 105lb ones with retainers.

It's a strong possibility I'll upgrade turbo and exhaust in future so maybe 370ish rwkw is on the cards and not sure if the 1808-24 items will be up to it?

 

Cheers,

 

Rob.

I recently picked up a set of the crow cams race valve springs and retainers https://www.crowcams.com.au/FindaProduct/tabid/92/ProdID/15792/Default.aspx

Installed Height - 1.520"
Installed Pressure - 105
Pressure @ .5 Lift - 205
