PaulStarletSR Posted December 22, 2009 Posted December 22, 2009 from a 5efhe!wot wud b the gains for my Sr??please b as accurate as possible boys as im dyin to improve my cars performance in anyway shape o form!!is it sumthin to do with the higher the lift,the more torque?!? havnt got a clue so help is needed!lol Quote
Sparky Posted December 22, 2009 Posted December 22, 2009 Dont think you would see much gain if any by just putting the cams in tbh.Would need some sort of ECU to raise the rev limit and alter the timing/fuelling to get the best out of them. Quote
ToyotaTech15 Posted December 22, 2009 Posted December 22, 2009 Im sure there is only 1mm extra lift so it's not going to show gains as sparky has said.If you can hold of a bit for Enzo's SR project that will bring some new exciting products to the n/a tuning market, Hope this helps a bitGary Quote
Nayls Posted December 22, 2009 Posted December 22, 2009 cams from a turbo in to a n/a will not help you! it "can" work the other way round though,n/a cams in a turbo,but only a mild improvement.generally n/a engine's have a longer duration than turbo's. Quote

You'd be better off first doing the basic breathing mods, then move onto headwork and fuel management. Quote

Asad Posted December 24, 2009 Posted December 24, 2009 Im defo looking for some decent cams aswell, for the sake of 1mm the 5efhe ones are just not worth all the hastle and the gains look to be minimal with little proven results. Quote

Asad Posted December 24, 2009 Posted December 24, 2009 Npe 4E-FE,4E-FTE, 5E-FE all have the same cam spec Quote
Nayls Posted December 24, 2009 Posted December 24, 2009 Npe 4E-FE,4E-FTE, 5E-FE all have the same cam specim not full of info on starlets yet mate so did'nt know that from owning r5 gtt's i know that fitting a cam from a 1.4 campus in to a gt turbo is an improvement,but vice versa would'nt help at all.thought it would be similar with these but obviously not.why dont you get your cam re ground to a better spec?
