1jzgte, can it make power? fit in a lexus?

hello everyone. i have come to you all looking for some insight. i have a lexus gs400, 93 model automatic trans. i was looking around for 2jz-gte swaps for it when i ran across the 1jz-gte. since the cost is so much lower, ive got to ask.
what kind of power can the 1jz generate in stock internal form? {but upgrading fuel system, turbos etc} how much can it produce with fortified internals {rods, pistons etc, big turbo etc etc etc}
thanks for the help

You've got a 1UZ-FE, why not chuck two turbos in?! It'll prolly cost the same as a complete engine swap. You get to keep the V8 torque, plus it's a lot less headaches 'coz you don't need to fabricate mounts, wiring, and all that other stuff.

I think it would work out cheaper for you to swap in a 2JZ-GTE. In Japan the Lexus GS300 (known as the Toyota Aristo over there) was available with a 2JZ-GTE from the factory, so if you get one of those engines it will swap into your Lexus very easily.
I bought an early-90's model Aristo front cut for AU$2900. You can see pics of it on my web site if you're interested. You can buy 1JZ-GTE front cuts cheaper than that, but swapping it into your car wouldn't be anywhere near as easy since AFAIK they weren't available in the Aristo/GS300 chassis.

well here a 2jzgte swap is gonna be in the 8000 range, while a 1jzgte is 1600. the sc isnt really like the gs/aristo, but it is the same chassis as the supra, and gs300/gs400 {v8 4.0 litre}
im figuring a 1jz should bolt right in since they come in a lexus type product..but who knows./
also what kind of power can be had from the 1jz? i am an automotive machinist, with chassis dyno and all that good stuff  so i can cut some of the cost out of it all

GS300 and GS400 have 2JZ-GE and 1UZ-FEs respectively... Same car, different engine.
SC300 and SC400 are different cars...

Dude, check this out.
www.swiftracing.com
They're even there in the US and can be had for 5K USD. Don't waste your time with 1JZ's (don't misinterpret this people) when you have a great base already. Supercharge your 1UZ.
Cheers Dave.

max and GT are right... why even consider a swap, when some forced induction on your current engine would bring you massive horsies.
one of the guys in the club has a 1UZ-FTE, and it makes big power, only running mild boost

i agree with the others why wast time with a 1J? sure its a good engine but into your chassis why not boost you current 1U? sure it would cost more than putting a 1J into it but after you spend the extra money working the 1J you would have probably less output than boosting your 1U with either a supercharger or two turbo's.
plus you have the bonus of that sweet V8 exhaust note and bucket loads of torque.

i have never been able to find a damn thing for the 1uz {of course, i didnt even know thats what its called.} however the thing here is cash. i can get a 1jz swap for next to nothing. i had considered a 2jzgte swap, but its gonna be harder to afford it. if anyone out there has seen mods to the 1uz lemme know, id love to hear about it..
im off to swift racing later fella's

i would also like to point out this car has a tight budget. the 2jzgte swap is the first choice if i can find one..but someone mentioned the sc400 is different than the sc300...how? different chassis? engine mounting points?
also the car has over 200,000 miles on it. the 1uz is tired. there is absolutely no room in the budget to pull the v8, build it, reinstall it in the car, then source a turbo or supercharger kit....there just isnt the money for that.
my goal is to swap a reliable turbo engine into the car, then later when the guy gets his money back up we can start working on performance upgrades, a little at a time.
id also like to point out the sc400 is automatic....auto is complete crap. plan to convert to a manual if at all possible. havent really looked into it too terribly much yet, but we shall see.

i know the gs and sc are different cars, but they are the same basic platform requiring the same effort to swap motors from one to the other.....as far as i know. though thed gs300 has a different shaped engine bay that does not allow the factory twin turbo setup to be retained when swapping a 2jzgte into it {gotta use a single turbo, OH DARN!!!}

No, the SC300/400 (Soarer) and GS300/400 (Aristo) are completely different platforms. I'm pretty sure the engines won't easily swap between them because the Aristo uses a front-sump arrangement while the Soarer is mid-sump.
The twin-turbo 2JZ-GTE WILL fit in a GS300/400. As I said before, the car was available in Japan with this engine installed - I know, because I bought one! If you can get your hands on a Jap-spec Aristo front cut, the TT engine will bolt straight into your car.
There's a lot to be said for keeping your existing engine though - a 1UZ with a bit of boost would go very hard indeed.

My opinion:
Go the 1JZ - They rock!.
If the car can fit a 2JZ, it can fit a 1JZ and vice versa as everyone ive spoken to about this and who has done it has said they are so similar in the bottom end like engines mounts and housings that theres no problems.
Theres been a few soarers around in the magazine that have done 1JZ->2JZ upgrades and use the same mounts, looms, and ecus! Easy as pie.
Read anywhere, JZ engines crank out power with minor upgrades, a pod filter, 3" zorst, more boost and s-afc and you're guareenteed at LEAST 300bhp. Do a large single turbo conversion down the track and you can go further. JZ engines are legendary for high outputs achievable with stock internals.
Other bonus's: parts for JZ's are easy to get, modifications to them are easy to get, and twin turbos.. the ladies love it
My 2c

you might want to chat to ummm <insert name here> with the 1UZ-FTE ... he was at the toymods dyno day, so I'm sure you could get in contact with him

You're thinking of Jamie Heritage.
He goes by the nick of 1UZ FTE here on the forums.
poombah, Jamie's twin turbo 1UZ-FE put out 245kW at the wheels on the last dyno day. This was enough to beat every other engine there and he was only running 7psi through it.
The 1JZ and 2JZ are great engines, but when you're comparing them to the 1UZ, it's just chalk and cheese.

whats 245kw in hp? thats like 330hp by my calc. is that alot in your coutnry? im used to seeing supras make about 400 at the wheels, all stock except for downpipe and exhaust, maybe a front mount, upgraded air filter/intake tube and of course a boost controller. i dont know if you all have strict emission rules or what not...here its really slack, i can basically do anything i want except for remove cats {which is still commonplace}

Our dynos show much lower readings than your ones.
Not sure what the average difference is though.

We use Dyno Dynamics.
For comparison, a 200SX (SR20DET) produces about 100kW. It's rated at 147kW from the factory. Gives you an idea of the sort of drivetrain losses we see.

Well, taking the drivetrain loss of the 200SX and applying it to Jamie's TA22, 245kW would be 360.15kW at the flywheel.

you must remember that in the SC300-400 the engine auto gearbox and digital dash are controlled by ONE! computer and if you use one in the GS400 that you could have some serious hardware VS software clashes.. be warned. also trying to find a 1J with manual trans is pretty hard cos you cant just get a manual box and stick it behind one that was an auto unless you change the engine management. 
BTW What does your budget extend to $$$$$$

well we are trying to get the motor in the car for under 6 grande u.s. {keep in mind labor, dyno tuning, machine services etc will all be free} im figuring if i use the 1jz the computer should plug into the lexus wiring harness. i know swapping a 2jzgte into this car is cake. so worst case why couldnt i just use a progamable 2jz computer and tune it to run the 1jz? also when switching from an auto to manual it shouldnt be that hard, the ecu may control the auto trans, but it doesnt need anything but a speed sensor from the manual. usually you can just leave the plugs hanging, use the respective ecu that matches the motor and all should be good....of course i could be completely insane.

Not necessarily... R154's are pretty cheap in the US. He just needs to find a 1JZ bellhousing and it will bolt up to a 2JZ block.
If he wants a 6-speed though, that's a different story!

Did the 1UZFE ever come with a manual gearbox? Ive never heard of one but they may exist.
How much would it cost for the 1U to be rebuilt? because 6k should be able to cover it if your dyno tune and labour are free. 
just use a low boost supercharger and enjoy

No, there is no factory manual transmission to suit the 1UZ. However, you can purchase adapter kits for the W58. I wouldn't expect it to live very long behind a boosted 1UZ though!

true
you'd probably have to fork out for the 6-speed box regardless, in which case you'd probably be better off getting a 2jz-gte

Jamie uses a W58 behind his 1UZFTE. Will be interesting to see how long it lasts, but his car is fairly light, so he wouldn't have to ring its neck to get it going places...
Knowing his skills though, it wouldn't surprise me for him to spin a new gear if he broke one!
