My daily driver is already over 300 horsepower I donít want to see my mk3 under 600. As much as is depressed me Iíll look at JZs. Any of yíall want a black box AEM?The 7M is pretty easy to build to ~450-500whp, relatively speaking. That's a fun, good sounding and enjoyable power level in a MK3 and you don't need to further complicate things with twin disc clutches, different transmissions, etc at that HP level either. If you could be happy keeping it around there, stay 7M.
But having done dozens of 1000+hp setups in a variety of domestics and 2JZ based builds - if the HP number is really what you're after, you'd be crazy to stray from the proven formulas and the 7M is anything but a proven formula for 600+whp.
You're not building a SEMA car to showcase anything or stand out from the crowd, you're not going to make thousands on 'the gram' with pictures of your hardparked MK3, etc etc. If the HP number is what you want, then you need to make a sound game plan for 1000whp right out front and these days that means JZ, LSX, or a Coyote. Any other answer is burning a lot more $$$ than you need to be burning just for the sake of having a less reliable build that will bring complication and cost along with it. Don't let social media and youtube fuck with your head on a JZ build being 'ho hum' or normal. How many 1000whp MK3's do you see on the road, period? Hell, how many clean MK3's making 200hp? A clean MK3 is a rare car these days, and a reliable build that will get and keep you out on the road putting miles on the car is what really fucking matters.
To that end, there's nothing wrong with enjoying the nice 7M MK3 you've got now and building it to that ~450hp level and just enjoying it. But if you really want the 1000hp, I'd do some soul-searching and strongly consider parting out the 7M stuff and going JZ.
A 2JZ VVTi 3.0L build will be reliable at 1000whp, be streetable, and with a Grannas T56 setup behind it there's no need to fuss with the rear end or any of that stuff for highway roll-ons. Everything about tuning and building that engine combination is formulaic.
If you do put it on the drag strip, drag radials and VHT will break anything and everything but MK3 diffs are cheap and just keep an eye out for subframe cracking/damage.
