Rb30de Cam Choice?

[Althotas]

G'day, building an RB30DE with velocity stacked RB26 ITB's with rb25 pistons etc, pissing vct off. Car will see around 7000rpm

Was just wondering what cams and cam profile you would recommend for it,

Thanks

Probably the biggest you can get. Even big turbo cams are small when run on a n/a. Probably 280's with 11mm lift, however you will have to spend a bit on the valvetrain. Personally i would keep the vct.

very interesting....why do you want to try for a big power/non turbo rb30?

Get on the phone to a reputable cam builder with your specifics. They will have something to suit your setup. Try Tighe Cams, or Kelford. Naturally aspirated cam specs are likely to be way different from forced aspiration specific.

Unless going for regrinds you may well find that VCT is off the menu too.

Should potentially be a good thing, plenty of snorting goodness. Please keep us updated with results, not just the cam specs you use.

Hmm interesting, so pon cams would definately be out of the question?

Can't drive turbo, just want a mean RB30DE for now as i got shit very very cheap and can get stuff done easily and cheaply

Thanks for that, i'll give them a call tomorrow and will keep you updated!

Rang up kelford yesterday, he recommended that i get a proper port and polish job done first and get the head flow tested and then give the specs to him and he will choose a cam profile from there, so that seems the smarter path to go

so who do people recommend for a good port and polish job? As where I am from nobody really specialises in it

Thanks

[Adriano]

Thats funny, as usually the head porter wants to know the cam specs first

yeah thats what I though...not point porting the head for massive flow at 11.5mm lift and then turn around and put 8.8's in it etc...or vice versa

If using a 25DE head, then be prepared to have some machining work in order to fit cams with that sort of lift and not strike problems with coil bind in the valve springs.
