Well you're definately searching the wrong forum for info on these motors lol

1jz wayyyyyyyy more support to make power and cheaper to make big power

1uzfe very very cheap to buy the engine itself, you will need a special bellhousing or adaptor plate for a 5spd transmission, more expensive to build for power (4 cams, 8 pistons etc)

they will need modified wiring or a standalone, custom driveshaft, custom rad, custom mounts, custom fuel, custom intercooler and the list goes on

both the 1j and 1uz will need "modified wiring or a standalone, custom driveshaft, custom rad, custom mounts, custom fuel, custom intercooler and the list goes on"..

personally i love my 1uz lexus and the way it sounds on the revv limiter. and a lot of people are pulling their jz for the uz motor too. it may be more expensive to modify but they handle boost well. my friend just dynoed a hair under 350hp on his 230k mile LS400 with a cheapie 1000$ single turbo budget. no fuel mods, no computer mods no nothing. just slapped it on and went.

with the 1uz you have a lighter motor and start with a better torque curve.

i know im gonna half to do alot of custom work im just wondering more on power because when i was looking at specs they looked real close on paper but i was wondering more on a first hand exp how they are because to me whats the internet is not always true and im also wondering about the aftermarket support

Seeing how your just wanting to drift go with the 1jz, slap a single on it and your good to go cause honestly your not goin to need more than 300 to 350, hell leave you can even leave to stock twins and run a bit more boost and rip it up.

Just the 1jz motor and transmission with computer cost more than my entire 1uzfe swap lol.

If you know where to look the swap can be found for less than 1600

The price of the 1jz swap alone turned me off of it and i went a different route. I'm a drifter, i'm on a budget and i just wanna get **** done so if it were me, i'd just do a 1uz. I had a hard time finding one nearby that i could get for a fair fetch and the r154 conversion kinda had me scratching my head second guessing wanting to do it but I WOULD HAVE done it if i could have sourced one quickly.

I just had to pull the trigger on a swap and invest money in it before the new year or i'd never get it done and lose interest in my car.

1uz all the way man.

1j's are cool as ****, make nasty power, sound nasty and are just legit but the 1uz is the path less traveled and i'm all for that.

i know there both great motors and i know they both make great power any of you know what factory internals can hold hp wise for the 1uz im kinda leaning towards a 1uz but i have found 1j full swap for 2k to my house

I'm involved in a 1jz-gte vvti (chaser jzx100) build at the moment.

So far we have a 60-1 and a manifold and a wastegate and a piggyback for the stock computer.

I will report back with results. This car made 193rwhp (genuine) through the auto, only mods being 3" pod filter and a incredibly BAD cat back exhaust (hks brand LOL).

Short term goal is starting at 0.8bar boost. Then rising it to 1.0-1.1 bar after a month or so. Long term goal is probably 1.7bar boost, cams etc etc.

Work will begin on that car in about 40 days

I've seen 500 on the stock internals for the '94 and earlier 1uzfe. They have only 10:1 compression and larger rods. Mine is a '95 which has thinner rods and 10.4:1 compression. We'll see how things go. Won't be my first high compression turbo tune. Did a 3.8 Mivec v6 from an eclipse gt which has 10.5:1 on a 62-1 turbo to about 12 psi tune last summer. Talk about beastial!
