I don't think the 20v is a beast LOL. Its a good motor but I am intimidated by it breaking and having to wait for speciality parts and then also having to pay for those parts. I agree with the GZE but the majority of those are now 15-20 years old. I do not trust those old SC12's and if yours goes bad replacing it becomes a pain. The last time Toyota had stock replaement ones they were $2,000 and you can build a decent 4AGTE for less than that. I am not putting down the GZE as it is a great motor. I just don't want it to break.

Another option alot of people have not looked over welding in the mounts is the 3S and 5S. After the mounts they become a bolt in affair. If you are going with S-Series tranny from a MKII then you do not have to hunt down expensive axles. Plus the junk yards are sitting full of these motors and are a dime a dozen. A 5SGE (5SFE block and 3SGE head) makes excellent torque and pull hard to 7500. It is the best of both motors and can be had pretty cheap if you look in the right places. You can easily make 200+hp with just bolt ons. The weight will not be to much over the stock set-up (maybe 50lbs). I am seriously rethinking my GTE build.
