eh eh eh....lol 1g cheap and decent. Cheapest swap IMO! Theres a few people away who dynoed their stock 1ggte supras and they getting from 187-194rwhp. Theres a few of them in australia pumping out 350-390RWHP with some good amount of mods but still, for an old ass engine it pumping out some decent numbers.
The 7M's only require up to 450-500hp to do mid 11's constant. WITHOUT nitrous
However the 7M's(GTE that is) came with like 240HP stock or so. AND THEY CARRY SOME GOOD TORQUE!
The problems with 7M's is the overheatage. You would need to put a better head gasket and retorque head studs but im not sure how much. The stock 7m turbo is upgraded to a 60-1 mostly and work very damn good at 18psi, this is where most people away make 400rwhp with.(The same turbo that in my 1G i get)
Look it have a 1g with box on forum for sale, they does pull nice with the gearbox but auto is shiet. Same goes for 7M but the 7m auto pulls nice but still shiet compared to driving it with a box. I CAN GET YOU AN AUTO COMPELTE 7MGTE IN BEST CONDITION FOR 5000$.
Yea 7m is drink gas but you'll like it.
Want more? 1JZGTE theres alot of them around and an auto 1jz will be good enough on a cressida, trust me. I did 14.1 with mines auto with the thing wired on econ mode and 8.5psi. Even with a screwy boost line showing me 4-5psi when one line was incorrect, i was doing 14.7 constant auto.
A 1jz will work in a cressida, but they come middle/rear oil sump, if you need a front sump and crankcase, i have one to sell if u decide this way. Also 1JZ's going for 5-7000 in bamboo now, Auto. But look like someone buying them out. lol
Forget 2jz in a cressida, believe me, that is some serious conversion. UNLESS you have the money and proper parts located.
For a cressida, i would suggest a 1JZGTE if you want a decent gas mileage, but if you want to do some slight mods and have a decent turbo to work with and get some good power, 7MGTE.
