most of the torque dropoff is due to the restrictive stock turbo. there are people running 8000rpms on stock cams. cams definitely HELP with top end, they allow you to run less boost and still be efficient, but they're not totally necessary.numbone said:cams is an upgrade a 3S definately would love. the powerband in midrange and top end of the stock motor is lacking in my opinion.
You are correct, (kind of). Toyota uses the same cam blanks for the GE and GTE engine. They used the same cam blanks in the GEN I GEN II and even GEN III 3S-GTE but that is where the simularity ends. The blanks are machined with different durations lifts, degrees etc... So, the profiles are completely different in different versions of the engine.NESW20 said:i have heard that OEM 3SGTE and 3SGE cams are identical. it is just what i have heard and could be bogus information.
