all engine managment is done. the electronics will come from split second, with the fuel map tuned by me, and URD should be able to help me figure out where i want the timming. i will def keep everyone posted....

Re: turbo header problems.

does anyone have any info on this seller/type of intercooler? the design would be much cleaner if i can get the in/out on the same side..........

Fabricating your own Turbo Header

Use schedule 10 SS in lieu of the Schedule 40 steel.

Re: turbo header problems.

that is a good write up, but, doesnt mention header size, just the process. im just going to take off my header, match the size to the ports, and order a box of random bends in that size and play jig saw puzzle. anyone know the min length i should keep the primaries? some say 14 inches.........

Re: turbo header problems.

Toyota v6's are historically very beefy under boost.
Most of them in good shape will run >400bhp without any work.
