2008 LS460 SWB
Smokey Granite Mica

It’s been along time build but wanted to document progress and maybe, be helpful or inspire other owners.

I peronally love this car. I’ve always wanted it but couldn’t afford it. But when I did buy the car, I set out with the intent to build a clean simple LS460 IMO. Nothing over the top. No offense to anyone who like that. It’s just not me.

Well, enjoy 🍻

March 2019

Came with 20” voxx wheels

Added some window visors

 

Installed D2 air suspension and Airlift 3H controller

 

Aimgain Pure VIP front lip paint matched at Maaco

OEM side marker

Part number

Made a custom badgeless grill because K Break was too much money. 😂

Done

 

Waiting on wheels to come in
VIP modular VR-01. Seen it on a slammed 460 from Hawaii and was inspired.

But while I waited:

 

Specs are:
21x9.5 +19 offset - front
21x10.5 +23 offset - rear

Air’d out

 

Rolled around in white for a couple years and saw IG: @kproduce_japan beautiful blue 460. What really drew my attention were the LS600 head lamps and the blue.


So I set out to look for some 2010 LS600 headlamps, 2010 LS460 sport fascia, sport grill, rockers and rear valances.

Had a knock off wald rear lip that I wanted to incorporate into this next chapter.



Fiberglass is messy

Clean everything up and prepped to wrap 3m gloss cosmic blue.

 

His and Hers

 

Cali roads are trash + low profile tires = RF wheel cracked in 3 places

 

Picked up as set of Tesla Model X 20’s While I order new lips and barrels.
OEM 460 center bore is 60.1mm and Tesla bore is 64.1. using hub centric rings to compensate the difference.
20x9 front. Tire size is 245/35
20x10 rear. Tire size 265/30

 

Wheels looking sunk in so I installed a set of bolt on hub centric spacers.
1.25mm up front
.50mm in the rear

Torqued to spec and checked for residual torque loss on the spacers after 25 miles. Lost 8-10 ft lbs so I retorqued them to spec.
Checked for residual torque loss again after 100 miles. 0 torque loss.


Currently (2024) how the car sits. Yes… this is ride height.


and where i came from….

 

Like I said, I wanted to build a clean and simple car IMO and I feel it’s getting there. I don’t see my self or my build as “stance”. Yes, I like riding low. But, I like spirited driving. Thats why I opt’d for air suspension.

Anyway, set out to do what I believe not many have put effort in. Waking up the LS460’s power. Probably satisfied with their LS’ performance.

Me - There is always room for improvement.

3” single pipe cold air intake.


Extended MAF wires. I did not notice an increase in resistance in the wires after the extension.

Installed OEM MAF sensors on opposite sides of each other to allow a free flow of air to each sensor. (They do not overlap). These are 76mm internal diameter MAF adapters of amazon. I figured if it doesn’t work, I didn’t lose much

Where the MAFs sit. At a stop light or in traffic, yes MAF temps are high but when the car gets going again, it cools down. Plans to re-route.


The piping runs down then 90 degrees toward the driver side, through the modified splash guard and the filter sits at the vent where the brake ducting inlet is (by the driver fog light). I was pressed on time so it would have to do for the moment. V2 is on the way.


AND, no check engine lights upon start up.😁 Induction noise was there and it was beautiful. I noticed an increase in throttle response on the butt dyno

 

Had a tune the day after I made the intake. Initially, I wanted to tune because of the lazy transmission.
The induction noise, lovely.
Before the tune, I noted short term fuel trims were high due to the increase of air flow.

Uncalibrated PCM trying to compensate

Highest KCLV achieved prior to the tune without the CAI retrofit.


On the dyno. Loi calibrated my MAF and began to tune.

Picked up power from the tune. Not bad for an intake and 2.5” exhaust on Cali 91 octane. Cats are on the car. I believe more power could have be made if the MAFs weren’t heat soaking on the dyno. That was on me.
But, I could definitely feel the gain in power. Especially after 4,000 RPM

Annnnnd, the lazy transmission shifts….. gone. Driveability was greatly improved. Shifting is quicker and smooth. I’m very happy.

KCLV after tune


Current fuel trims at idle.

 

Thanks for stopping by. More to come

 

You may have noticed the insanely high AT fluid temps in one of my photos up there. Not sure what normal operating temps are but I live in an area where summers are hot and I drive in traffic.


Removed front fascia

Find center on impact beam and installed some rivet nuts

Cooler mounted

Reinstalled impact bar with oil cooler

Front fascia reinstalled



AT oil temps sitting at idle after transmission cooler install.

I also serviced the transmission by replacing the transmission filter and gasket. OEM Toyota/Lexus WS ATF. The removed fluid was reddish with a tint of brown. Mostly red and still translucent.

Waited until 103 degrees F and opened the overfill port to remove excess fluid. From cold start to nominal fluid check temps took about 12 minutes.

 

Been working almost 2 weeks to convert the LS’ TCM over to an ISF TCM.

Short story: IT WORKS
Confirmed today 5/11/24

After a deep dive in TCM pin out schematics for both vehicles wiring diagrams, I was able to map out all connections from my 08 LS460 over to a 10-12 ISF TCM. That took less than an hour

The real work was re-pinning the LS’ connectors.

I bought a used TCM and confirmed operation on my brothers 12 ISF.

Once that checked out, I just dove right in and re-pinned each wire one by one because the used TCM I bought did not come with pig tails.

39 active wires for ISF
40 active wires for 460

I know what the 40th pin is for.

I wont share, it’s the easter egg find.

Get in the wiring diagrams and you’ll find it.
The prize is, if you want do this retrofit, you know it works.




3 more wires!!
