No... the 3SGE and 3SGTE internals are different. The 5SFE is gonna show more big horsepower numbers because of the head design and the HP formula. The FE head design is excellent for making big torque numbers with boost... even a bit better than a GE head. Whenever big torque numbers are calculated with the HP formula... you get big HP numbers (assuming you have a decent rpm range). The FE head, in a sense, is far superior in making low-mid ranged torque. As for lago's reasons... the reason Toyota didn't put a 5SFTE into an alltrac or something... it's all about torque delivery. If you look at itchy's dyno... the torque is maxed out at around 4200-4500 rpms. There is significant drop off between 4500 rpms and 6000 rpms (from a peak of almost 200 ftlbs to around 120 ftlbs)... The 3SGTE on the other hand... does not do this. It maintains its torqueband and doesn't drop off until 7000 rpms or so. It can keep making power with more modifications... but as far as racing is concerned... even though the 5SFTE makes that good amount of torque/hp... it's not in a very effective spot in the powerband. The 3SGTE makes its power where it counts and then some. As for everything else... the 5SFE compression ratio is 9:5:1... Its internals are completely different and no where near as strong as the 3SGTE's. I agree with lagos that a turbo 5SFE will see problems if shortcuts were taken and tuning is not good. The life and death of a custom turbo kit (and the motor) depends on the details you do or do not take care of. As far as making power is concerened, the 5SFTE will always make more low-end to mid-ranged torque than a 3SGTE pound for pound. Displacement and the FE head are the reasons. -------------------- "It's ok to be naked girl... I'm an artist!"
