new cams!

[IH8TEC]

damn thats some exspensive power. how it's more driveable though

[Grrrrrrr!]

you could try CSL cams.. they have 20v 4age cams for $600 which they describe as TRD spec (Rally Sprint). whether this means they are copies of TRD cams, or genuine TRD cams i don't know. they also have a whole list of other head work they can do to 20vs.. everything from mild to wild.


NOTE: i have no association at all with CSL, i just happen to have been investigating what parts are available recently

Billets are better, and with regrinds you either need to add more meat to them to give them lift (then shim changes) or grind them with standard lift and extend the valves (bout 70 thou).

base circle regrinds give you both more lift and more duration
with any base circle regrind you will need to reshim

billets give you the advantage of no need to shim and also keep the cap to lob geometry the same(critical on rakcer drivin valves


.... just clearing that up
