1999 Lexus LS400 engine swap 2jz or Ls?
hey Guys this summer I知 doing a big engine and trans engine swap in my Lexus. I知 still deciding if I want to keep a v8 and go for some big ls motor or just buy a 2jz gte (turbo duh) I really want to make it manual too if I知 going to go through all that work. Another big thing is I want to keep my nakamich sound system and ac. If you have any tips or advice or opinions or any knowledge let me know!! I would really appreciate it... and yes I will definitely be posting pictures soon! I知 taking the 1uzfe out any week now :3

it痴 hard to find superchargers for 1uzfe痴 that are even priced nicely at all. Even if you do find someone who makes them the wait is several months and they would have to ship it over seas. So that痴 why I want to go with a 2jz and ls they are cheaper and quicker. Also the 1uzfe its a lot harder to make more horse power without upgrading the engine and if you do upgrade it there are no speed parts for it besides some cams

You just live in the wrong country and have the wrong year 1uz. A couple of local guys are over 450 to the wheels on untouched 1st Gen engines and rear mount single turbos here in qld aus.
The OG fe can throw down serious power without being touched at all.
You are looking at a lot of dollars with either. If it was me I'd sell it and just buy a crown with a 1jz. Will save you dollars and hassles.
Out of the ls and the 2j, the ls has a lot of support but it's really apples and oranges

Congrats on the pickup but you need to research a lot more. Swaps are neither simple nor cheap, and modifying your factory engine to 300+ rwhp is going to cost a good bit of change. In a car like the '98+ LS400s there are additional multiplex/body ecu concerns as well.
What have you driven before setting this lofty goal of 600+ rwhp, I mean no offense but your sound a bit green. Start off by reading up and do some base modifications. Before you start wanting to add power there's a lot to be done to the suspension, brakes, steering, tires, etc... That's a better place to start rather than thinking about swaps right off the bat.

was actually a nice 2012 5.0 but yes the reason I want that much is for the heck off it really. I do some minor drag racing. I want to get into drifting. I want to build just a fun Lexus for playing around with and just to show off the LS400 as it痴 a cheap start for projects

what's your budget?
we all want that 600hp number but the reality is money IS a factor in almost every circumstance.
as PD stated, these cars aren't as easily modified than older cars, especially with lots of engine/powertrain mods in sight.
converting to manual has enough hurdles on its own!

Trans swap is 4k aud. I'd rather fave a single turbo kit for a stock uz than swap any day.
Stock uz can handle quite a bit of boost

Simply put, unless you're a talented fabricator, there's no way to build a reliable VVTi 1UZ with 600hp for anything less than $8-10k+ USD. The trans mods alone would eat up about 1/3 or more of that. Labor for custom fabrication will be a big chunk of this.
So get your wallet out. Anything's doable with money.
