I'm (re) building my 4a-ge and i want to put some other camshafts in it.
but what kind of cams would be good?
i'm going to incrase the compression ratio and do some headwork + itb setup.

what cams would be good for this one? i know about changing the valve train..

but what duration/lift?... idle and normal street driving kept in mind please

thanks in advance

First.... the BS in this thread is OVERWHELMING...

second... DON'T believe ANYTHING without a dyno sheet to back it up!

third... names mean nothing!


ABOVE is my opinion..... BELOW are JUST FACTS!!





4AGE - smallport head with proper and precise porting.

intake bowl...


exhaust bowl...



exhaust port as it leaves the head...



10.75 to 1 measured compression ratio(included the gap between the piston and cylinder wall, down to the first ring) stock Euro pistons, with the combustion chambers lowered to 33cc - this was done by having the head cut along with the porting above







Web Camshafts... compare these to many of the "264" type camshafts with similar duration when measured @ .050" - 226 degrees



145hp and 112#/ft of torque measured @ the wheels. Numbers measured @ the crankshaft would be about 170hp and 134#/ft of torque. These #s are a bit low, since the cams will make power to 8400 rpm. Right now I have it LIMITED to 7500 The powerband is in excess of 4500 rpm (from 3000 rpm to 7500)




Oh... the only non stock mechanical parts are valve springs - TRD type. Wrist pins - lightened aftermarket type and the camshafts and timing pulleys. The crank, rods, pistons, rings, valves are all standard Toyota parts
