I hope when you say double up hg. you don't actually mean putting two hg in. 1st of all write down what your goals (ie: hp, streetability, drag, dyno queen, hard street driving, race or pump gas) are gonna be then ask the question again.

 

I think there is a headgasket sold tht is two headgaskets riveted together, anyway as far as not being able to get a 2jzge for under 4k$, they can be had all day long for 3.8k$, and if you get lucky for much cheaper. Lthough most are aristo clips, so you have to change a few things. But Supra engines are going for ~3.5k and up. like SRO said state your goals then bhuild accordingly. I dont know the threshhold of the stock auto, but i like stick so I never looked into it. As far as setup of the GE engine you are looking at a more restyrictive intake by the looks of the design, more plumbing for a front mount, a distributed ignition, the flange pattern on the head is different, so there is less support for aftermarket exh manifolds, etc etc. if you have the pockets go full out 2jzgte, or if you want do a 1jzgte swap for 1.2k$, or go middle of the road w/ a GE bottom end and a 1jz head... thats what im going to build later this summer with my GE block for my MKIII. Good luck with whatever you decide to do.

1jzgte how strong are those, about how much power could that engine make but still be a daily driver ?
