laxusls430

I haven't seen one anywhere but is there any manual tranny swap option at all for ls430 or are these forever auto with 3uz?

This is a rabbit hole that's been discussed more generally for the 3UZ and less specifically for the LS430/GS430.

Basically, the 3UZ (actually all UZs) has the same flywheel demensions as the JZ engines.

Here's a link to google with more information

Two problems - you're going to need custom transmission mounts for the LS430 and a way to mount the clutch pedal.

The SCs had manual options from teh factory and the capacity to bolt a clutch pedal to pedal mounts, they're the easiest to swap.

The other problem is that the 3UZ makes way more torque than most of Toyotas other engines - I think it makes more torque than the stock 2JZ twin turbo. The only transmissions that can really handle a regular 3uz are the V161/V161, which are really expensive.

I think you can build an R154 to take the torque, but if you do anything to the motor, you'll likely blow the transmission.

There's a thread on the front page of a guy who swapped a whole new powertrain into the LS430. Frankly, that's the best way to do it if you want a much faster motor and a manual transmission.

The answer would be... WHY would you such a thing?!
You already have a tiptronic function that makes you feel more manly and feels like driving a manual.

The LS is a luxury car, it is not meant to be yanked and driven like a dragster. It is designed to be a smooth and peaceful car. I just don't get it with the manual.


For everyone's info.. Did you know that the A761E transmission of the 04-06 LS, is the worlds lightest 6 speed transmission ?

Alright I've researched this and I'll give you some info. You can buy an adaptor plate or a bellhousing to go from the r154 to the uz. The hardest part will be engine management. You'll have to go to a standalone ecu. Megasquirt or aem come to mind. The shifter is an issue too, though what the guy with the lsx swap has a pretty clever setup. You'll probably have to move the shifter back, and to the left to get a setup like his. There's a version of the r154 that uses a shift linkage which would eliminate the need for a shifter extension.

As for torque ratings, the r154 is really stout. I've built a few cars with that tranny that are pushing way more power than a 3uz will ever make and they're handling it like champs. If you're worried the r154 from a pontiac solstice is much beefier.

im doing the NA 300zx trans. Got it for 100$ from a friend. Collins adapter plate for 315$ and collins clutch kit for 500$ going to use the gs300 driveshaft and weld on the 300zx trans end. Ive done it beforr lol. Trans shifter should line uo in oem shift hole. My ecu is tuned so i doubt ill have issues. My IG is s13__anthony if youd like to follow

Who tuned your ecu?
I have a intake mani ready for porting and opening up the exhaust a bit but I’m not sure how much that would yield, even with a tune
Has anyone 2j swapped ls430??

Here's one, apparently using a transmission out of a Pontiac solstice, someone makes an adapter plate and remaps the ECU to manual

it's been done, seen it first hand

I offered to buy everything and take it with me, they declined.

This swap has been done more than once, https://instagram.com/larrys.chopsho...dium=copy_link this Instagram user has an 01-03 with an aisin AR-5 5 speed out of a chevy colorado, i assume he’d be willing to answer questions if you have any!
