This is just a general question that I'm sure someone will file under the "stupid questions" category, but for those of us who are "mechanically impaired", this might be useful.
OK, I was comparing the specs for the 5SFE and the 3SGE engines, and I saw that the 5SFE has a slightly higher torque rating than the 3SGE (145ft-lbs, and 142ft-lbs, respectively), but the 3SGE has a much higher HP rating than the 5SFE (177hp, and 135 hp respectively). Can someone can explain to me how this is possible? I figured that if the 3S had over 40hp on the 5S, then the torque rating would also be much higher. Also, if someone did a 5S to 3SGE swap, how much of a performance difference would they feel with the torque ratings being so similar? Any input is appreciated, and remember to be gentle, I'm mechanically impaired. -------------------- "To be the man, you have to beat the man..."

its simply because the 5sfe is a 2.2liter block and thee 3sgte or ge is a 2 liter the extra displacement in the block provides more torque but the head on the 5sfe is economy design so you only get 135hp if u swapped the head on the 5sfe wit ha 3sge or gte head you would have massive hp coupled with alot more torque than a standard factory built 3sgte/ge...and for a comparison between hp and torque...if u have a small 1.6 liter 4age with a turbo on it that dynos at 400hp that 400 is gonna be at 7500rpm or so which means you have to run the gears out real far more torque means more low end power at like 1-3rpm
