Default 5.3 lexus ls400

lots of time has gone into this build so far and lots left to go. I have made all of my own parts for this build. I made my own mounts, oil pan, harness, turbo setup( in the works now) Let me know what you guys think

It is a 5.3 from a 03 suburban fresh stock rebuild with a tr220 cam and comp 918 spring. I am running a built th350 with a revmax 3200 stall with anti baloon plate, i have a 66/72 borg warner turbo and will be running water/methanol injection with it too i will be getting nelson performance to do my tune

Hee-hee...
What kinda of numbers is the engine putting out?
Any mods to the firewall or tranny tunnel?

The gear selector seems out of place in there though.

interesting, not sure if im a fan but LS-series motors do offer pretty good bang for the buck.

what are you doing with this car? drift bucket or?

Damn it seems like a waste to not have the t56 bolted up. Oh well not my car. Good job on the swap.

the car is planned to me my dd/weekend strip car i am a fan of automatics so thats why i didnt go with a t56 plus the price of one is rediculous plus all the extra work to make the car a manual. As far as the clearances nothing was cut or hammered it all fit in awesome only thing i had to do is drill some holes for the shifter. And as far as messing it up i didnt mess it up i made it better have you ever tried to price out performance parts for the 1uz its rediculous in cost with this motor for the fulll swap and extra goodies i will have about 3000 bucks into it and should be close to 500hp with just the cam i know the car will be about 325hp so with alittle boost im hoping for close to 500hp but we will see

What was messed up? This looks like a perfectly clean well thought out swap.

Beast, indeed. That turbo is large. The stock LS engine is awesome and gets great gas mileage, but if you want power, it makes sense to go with something with a better hp/$$$ ratio.

Your setup with a 6-speed manual transmission would be a setup I could only dream of. It may be too beasty to drive on the street though, but then again, people daily-drive CTS-Vs just fine.

I'm always very respectful of people taking on projects like yours and actually completing them. It isn't a small undertaking.

for the manual trans addicts, please note he wants to DRAG this car, a built slushbox is a good idea. personally im surprised he isnt running a TH400 or 4L80E with a trans brake...

He says he's building a daily driver/weekend warrior street car. Agreed though, a good auto tranny will outshift any of us any day and automatic transmission is much better for keeping a boosted car in the powerband. I just think the LS with a manual transmission would be great.
