From what I hear the 2jz is an awesome motor, I've seen dyno videos over 1000+ rwhp with a twin turbo setup MKIV. Also from what I've seen 93'-94' N/A MKIV supra can run you quite a bit upwards of $17,000 not to mention if you want a low mileage turbo, or maybe even a twin turbo nice nice MKIV then you are looking at $40,000+. Haha they are nice cars but personally I find the MKIII style more aggressive and a little easier on the wallet. And hell if I can get my 7mgte to over 500 rwhp who the hell needs a MKIV
And by easier on the wallet I do mean quite a bit easier. I bought my 86.5 N/A from a guy for $650 with no body damage but a blown engine (perfect). Later I paid $978.75 for my low mileage 7mgte JDM motor.
Good luck
