sport camshafts to 3s fe engine Options

[dolat]

Hollow, I have Toyota with 3sfe engine, and I wanted to have better performance and boost power so I made up mine mind to assemble sport ( more sharp ) camshafts, I have done it and I have some problems: my engine works loudly, like disel engine, so my questions are; is it typical of sport camshafts or maybe there were some mistakes with design or the way they were made or they were wrongly assembled. If you have any suggestions how to modify my engine please send me info….Dolat from Poland

You can only adjust shim over buckets in very small incriments... to truely adjust them... you need to get new re-sized buckets.

As for your engine running bad... Camshafts are NOT bolt-on performance parts. They require significant tuning to get optimal performance out of them. You'll need to get some sort of piggyback fuel controller (SAFC, E-manage) and get that thing really tuned. Depending on how agressive of camshafts you got, it may not make any power at all. Camshafts greatly alter power delivery... it's not always bigger = better. More power can be had if you open up the intake and exhaust a bit. I think you need to do some serious tuning.
