20V ST - ugraded cams?

[blue_leaf]

First question is where can I get them from in Australia?
What are the biggest cams can I use with stock ECU? What can be done to raise the rev limit of stock ECU - is it reprogrammable at all?
What is a safe rev limit for an internally stock 20V ST with cams and programmable ecu?

not sure where u'd get em, but the max lift you can run is about 9mm and that has to be a shallow profile too otherwise you may or may not throw a shim.

raise the redline? now why the fuck would you raise the redline on a FACTORY engine? even with say 264 cams you are gonna hit peak power and torque before 8500rpm, so dont even bother. but if you are set on it, reducing the reciprocating mass is about all i can think of

search ffs, on here clug4ag and ae86dc have the 200hp blacktop thread, look at phil bradshaws web pages, and if you havent already done so (im willing to bet it)read the FAQ

is it still school holidays?

ive got cams on my 16v from crow cams which are in melbourne. From memory the standard 20V cams are about 250 duration with 7.9m lift (i think) so youd probably be limited to about 264 duration although it probably wouldn't last too long on a stock ecu, also your idle will be quite high Wouldn't change the rev limit since it'd be pointless unless you're getting huge cams that all your power will be up the rev range, but that would be useless without aftermarket ecu

My 16v had 275 duration with 10mm lift on my 16v with the stock ecu for about 50km and that sounded like a rotor hahaha
