Rebuild Motor

I was wondering does anyone know where I can find a factory service manual for an 07 toyota tundra? or just any website that will help me see a take down of this motor.

Ironically I had to find pics of the engine parts on fleabay to see things I wanted to know about the motor (block web size, oiling, heads, placement of studs, cylinder sleeve sizing ect...)

I am considering using the 3ur motor for a land speed project and needed to know how Toyota handled some things that would make or break the platform for ultra high HP.

BTW:

The motor is very capable, with some minor work of 1000+HP

Good luck finding what you are looking for.

I'm replacing the stock rods with forged rods, pistons, studs, and bearings. There 4x the size of stock ones so i know no matter how much HP I add to the truck the motor won't break. hopefully thats the plan anyways

Land speed project sounds fun. did you decide to go with this motor or something else?

I have multiple engines to run several different classes and 3 current vehicles: a modified sports, a streamliner and motorcycle (*one in testing stages). My current engine platform is busa based and while I have set some world records I have some unfinished business I need to attend to.

My goals are +375mph with the turbo motor 325 with the big bore stroker NOS engine in the liner.

And....


If you are going that route and making big HP, you need to consider sleeving the motor. Trust me on this one.

Darton Sleeves Incorporated

Also....


Send the crank to someone (I use Marine Crank) and have the crank ultra balanced, polished and nitrated. This relatively inexpensive mod will help prevent from spinning bearings when making big HP.

BTW:

The sleeves were the only thing that I could see that was a concern about the engine. There is not a lot of distance between the sleeve and the water jacket. While you may not have a catastrophic engine failure there is the very real potential for loosing a HG between bores or into the water jacket. If you cant do sleeves (about 1300 for the sleeves alone) consider O ringing the block.
