Hi I love your web site its great . I have been into lexus v8s for about 5 years now my first encounter was when a friend of mine wanted me to build his new cobra replica . we tossed around ideas for a few weeks while the chassis and body were being built and decided on a 1uzfe with twin turbos and what a great car it turned out to be has won 2 national cobra events show and shine and is very compeditive on the track best mile todate is 12.4 @118 mph traction was a problem. The first pair of turbos were t25 s which made boost from 1800 rpm all the way to 5500 rpm but they were working real hard a bit to small. We used water methanol injection. To control intake temps. That was over 4 years ago last year we upgraded the turbos and fitted a garret intercooler.

The turbos we used are t3 plain bearing off a vg30det us spec. which has steel turbine wheels.

The intercooler is a 600mm x300mm x 110mm . rated around 800 hp. It makes 400 hp at the wheels and 1400 ft.lbs of torque on a dyno dynamics dyno. Boost starts now at 3500 rpm and goes all the way to 8000 rpm.

My cobra has 1uzfe as well but with a large single rayjay turbo. And a trust drag intercooler .also motec m48pro to control things.

Mine makes around 450 hp at the wheels and around 1535 ft/lbs of torque. It is always under development next is a full race cobra with alloy chassis all wheel drive 8 throttle body injection with 300 hp and weighing in at 1450 lbs.

I have attached some pics for you too look at. I also do a lot of engine swaps using the 1uzfe so far I put them in a 80 series land cruiser / 4runner / a hilux ute / and I am in the process of putting 12 in my ford ute. I do wiring looms for conversions using the crown cuts as it has 2 computers 1 for engine and 1 for trans so it is easy to use a manual transmission with a stock ecu.

Any way I have dribbled enough once again great site I just need more time to get on the forums.

Regards Scott Hampson.
