more power from rb30

[ucwepn]

How much of an improvement would a RB25DE twin cam head mated with the RB30E bottom end make? (Just curious)

34% increase at the wheels on an NA (according to Zoom magazine)

 

[rb26dett]

I remember that issue.

yeah i helped a mate with his na twin cam head conversion and it was quite a noticable increase

 

[Youngblood]

whats the cost to do the conversion? worst case scenario and best case? what head should be used? the vvti ot non vvti?

 

[Dose Pipe]

if pannic can run .6 seconds slower then quikvl and quikvl has a twin cam head is there any need for 2 of them?

 

[walesy]

umm yeh dose pipe when the quickest vlt times are so close together .6 of a second is a good margin
