Sc300 vs Sc400 swap efficiency
Hey guys, so I need a little advise or just some input. I currently own a 92 Sc400 with 251,000 on it. My plan which I already have started to put money aside for is to do a 2jz-gte swap and mate it with a R154 which I already have. My question is whether there would be any benefit in selling mine and throwing down some additional money to try and find a clean sc300 with a 5 speed or even an auto. Basically which Sc would be the easiest and need the least amount of fabrication to do the swap I want. My goal will be to put down around 400-450 HP on a single turbo. Thanks!

Just keep your sc400. The money you would spend extra trying to find a factory 5spd is far more than buying the 500 in parts from Driftmotion to make yours a 5spd.
Smart choice on already having an R154 trans. Get yourself an 2jzgte and get all of the stuff to swap it over. And please do the 90k maintenance and change all the seals while its out of the car. Now with the r154 you do need a 1jz bell housing and 1jz flywheel. There's another 3-500 depending on where you buy them. Don't forget to get a good clutch there's another 6-800. Then you will need an 2jzge harness to mate with that aristo harness. Used 2jzge harnesses are 1-300 depending on where you find them. Send your aristo harness and 2jzge harness to tweak performance to get mated together 800-1000 depending on options you choose. Going to need some motor mounts the sc4's won't work ( I may be wrong ).
You going to be on a budget. Get a log treadstone manifold and a cheap holset turbo off a diesel. Going to need some USDM 550cc tt injectors. Those are low impedance so get a tt resister box.
Gonna need a standalone or piggyback. Personally I prefer standalones.
This is all off the top my head. I'm sure there's more. I'm currently about to start my sc300 2jzge to 2jzgte swap so yea I been researching.

it all really depends on how much you can sell your sc400 for and how much a sc300 is. Having a sc300 will minimize the cost of swapping a aristo motor because you have all of the parts to swap it over. If you love your sc400 and wanna keep it then by all means do that. If it was me i would definitely find a sc300 auto and start from there. You can go NA-T or 2jzgte swap. You have spare everything since you have a 2jzge motor. Rear sump pan. Motor mounts all the stuff you need to swap over a 2jzgte motor. Now you have spare alternator, starter, PS pump a/c compressor etc etc etc not to mention you will have a 2jzge as a spare motor.

Thanks guys, I just wanted to make sure it wasn't too much different swapping a sc300 or sc400. Some of the threads I read made it out to be a bigger deal than I think it really is. Depending on where I am financially in a year or two I still might just try to sell mine to get a slightly cleaner body.

get a lower mileage car, dosen't matter if it's an automatic or not. you will be making it a 5 spd anyway.
i understand your concerns with high mileage like that. but be aware you will be spending thousands more in suspension upgrades/replacements. it's not just about throwing a motorswap in it and calling it done(trust me i know).
so if you want to jump ship after a short time, then don't bother. otherwise look for a lower mileage car(don't expect to get much for your current one). then go from there.

shouldnt be any fabrication if your swapping the whole powertrain.
just PLEASE dont call it a SC400 after youve done the 2JZ swap. on youtube, craigslist, ect I hear of "500hp sc400" or "5 speed SC400" and its just another 2JZ swap..... its disappointing lol

im in the process of doing the swap in an sc400 right now, there are differences, one of the bigger ones im dealing with right now is that the power steering lines are different.
also with an sc300, you have the right motor mount brackets from ur 2jzge. I dono if the 2jz comes with different kinds as well, but right now im waiting for the correct motor mount brackets for my 1jz (off a chaser originally)

Have you ran into anything else harness wise. I have the motor mounts already because i have a parts car sc3 with the 1j/r154 im just making sure there are no other surprises i may run into.

Sc300 is easier, I find that typically you can find one pretty easy (auto). It makes alot more sense to start with the 300 so unless you absolutely love the 400 I would try and sell it and find a equivalent or better 300.

sc300 is easier because you get the mounts, you get the rear sump pan (aristo is front sump wont fit), and the sc300 is set up for A/C lines that will plug up. on the 400 you will need to rework some lines and I am not sure about the body plugs. Read 1JZPWRD's swap thread, its a 1jz, but he did it on a 400 so you can see what all is different.
