Was there a bi turbo STI?

[555BCTurbo]

My uncle is an engine builder in Auckland, New Zealand, and he has built and driven many of the cars with the twin turbo setup. He said they suck to drive because there is a dead spot between the turbos. He was building a 750 hp EJ20T for a rally car when I was there last, and was using I think a T04 on it, as he said it will be much easier to rally.

Ya, from all the info Ive sourced so far, Im thinking this is gonna cost twice the money, to make half the power.

After some googling it seems to be the turbos from an EJ20H rated for 260 PS. Came in GT's (auto or man) and GT-B's, RS's (auto only)

Right on .. EJ20K , EJ20H and EJ20R were TwinTurbo-ed.

I have those heads on my engine, I measured the valve lift at 8.2mm in and ex wich is pretty near the STI heads. You can easily convert them to a single turbo setup with some little imagination to block the oil/coolant ports on the driverside head, and have a spare single-turbo coolan feed pipe to swap on the passenger side head.

I also use an SDS management it's a nice setup you are bulding i can tell you haha Don't bother the small turbo, go for the TD05 directly

I thought that on the tt engines there were two different size turbos. The larger spooled the whole time while the smaller turbo kicked in at around 3500k. I thought i read that some where from an article on a liberty b4.

Small turbo morgie? T04 is not small, it's a Garrett more often called a T4. The TD-04 Mitsu turbo is small.

Heres something for you all to drool at.
