Put a Mustang transmission in my Daily Driver Lexus? Why not? (Video)

[DarkTactics]

2002 Lexus IS 300 with a GTE swap running a Precision 6266 with supporting mods. Car was meant to just be a good daily driver which turned into "sleeper" more often than not. Wastegate is recirculated, still has stock muffler with a vacuum actuated dump just before it.

It's the first IS in the world with a Mustang 6R80 transmission (6 Speed Auto). I do hope to get some higher quality video soon. Hard to do it yourself.

• Quick Spool Valve, T4 Log Manifold, Gen 2 Precision 6266 Turbo
• AEM Infinity ECU
• FACTORY shifter (Leveraged a Fox Body Shifter Cable)
• FACTORY steering wheel shift buttons (For Manual Shifting)
• Everything is bolt in (Can literally swap this to any other IS)
• Custom Trans mount
• CCI Custom 3.5" Aluminum Driveshaft
• Circle D Custom Torque Converter
• Used 6R80 with Custom Billet Bellhousing
• US Quick Shift 6 Trans Controller, tied into to AEM Infinity
• Rear Mounted Trans Cooler

Car made 500+whp at 19PSI. Breaking in this setup and working out any kinks over the Michigan winter, and will turn up the boost once spring hits

That's a pretty cool little sleeper

I guess my only question is "why"? Definitely cool though.

[HybridZ28]

Pretty sneaky with that black front mount. I like it!!

Seems like a ton of work. I would have just LS swapped it for half the cost and effort.

So how are you controlling the trans?

It's in the list and video. US Quickshift Trans Controller pretty solid unit, plugs right into the trans, and just had to wire a few things into it. (RPM, Shift Buttons, Manual Button, etc)

What was the reason for the trans swap? Is the FoMoCo unit stronger or quicker shifting than the Lexus trans? Would the stock unit not hold up to the power level you are hitting?

Badass. Swaps FTW

I was wondering this, as well.

Yep, big time. The 6R80 is good for 700WTQ in stock form and about 1K hp. The factory a650 even after being built pooped out after 2 months of driving at only 19PSI (550whp).

Especially around Detroit, I have a trans that I can find plenty of parts / replacements / etc for, and it is a 6 speed. The shifts are definitely faster and keeps me perfectly in peak power band which is huge.

The biggest advantage is old trans tech vs new...

I have full control of shift points, shift firmness, TCC lock, a transbrake is built in, and I can switch performance maps on the fly. (So it can be like a factory luxury car, or full race mode)

thanks for the explanation.

Wow, that's really impressive. Your car(s) are sick

Thanks! I think I have a problem, as the fleet is rather large, and I don't wanna get rid of any until I know what I'm doing

Yeah the whole multiple 3000GTs thing is.... strange.

But you like fast cars so it could be worse.


I mean at least you don’t own a Toyota landcruiser.

Would be strange for a normal person but not for OP.

Darktactics, how many 3/Ss have you owned or had possession of? I think by the time we were out of high school you were over 10.

I always wanted a Stealth RT/TT but the horror stories kept me away. Now they are all either beat to shit or never driven and crazy priced.

I always seem to be shopping vehicles that fall into that category.

Oh man. I've probably owned 40-50 at this point. There are others who put me to shame nearby, but it helped pay for college and helped me keep a healthy collection of spare parts. I honestly need to figure out which ones to keep.


91 VR-4 - first car I ever owned... do you really get rid of that? (I've been leaning more so ever than before)
97 VR-4 - perfect amount of mods. Perfect driver. 76k miles.
99 VR-4 - 11k original miles, fully built stroker motor, needs some work, but 11,209 ORIGINAL miles, I'm the second owner. 1 of 287 in existence.
95 Stealth - The only car I have with the pop out roof... 86k miles.

What's wrong with Land cruisers?

Somebody has to be anti- landcruiser/scion to counter all of Rich’s spam.

I think he's probably the only one that isn't anti scion lol.
