The way the EJ engines are designed, and the engine compartment of the STI itself, is specifically suited to fit one turbo. But, anything is possible with custom fabrication. Doing something like twin turboing an STI though would cost too much money, you're looking at over $20k.
It would be a much better choice to simply put a larger turbo on. Less money, more simplicity, more reliable, easier to work with, probably faster as well.
yes, the WRX and STI are both turbocharged.
it is a game
It depends on the model. The WRX and WRX STI models have a turbo. Like most Subarus, if the Impreza has a hood scoop (for the intercooler) it has a turbo.
The answer is a little long to answer here, but here is a link to Subaru Drive magazine that has a good explanation. http://www.subarudrive.com/Spr03_TurboBasics.htm
For a 1994 Subaru Legacy Twin-Turbo RS with a manual transmission: Horsepower -206kw/276hp 0-60mph - 6.5sec Top speed - 155mph
STI stands for Subaru Tecnica International. For years the acronym was STi but then it was changed to all caps, STI. In addition to supplying racing engines for Subaru rally cars, STI markets performance parts for use in many Subaru vehicles. See link below for STI HQ.
no a ts-r is non turb and a gtb is twin turbo
Subaru Impreza WRX STI was created in 1992.
12 psi in both ranges
As far as I know you can not get a subaru legacy sti from the factory bu you could get an sti engine and put it in a legacy. That is the only way that I know of.
The Subaru Impreza STI can be test-driven at your local Subaru dealership. Call your local Subaru dealer for more information.
Some of the rarest ones are the white Subaru WRX STi, the Fujistibo Subaru WRX STi, the HPI Subaru WRX STi, the blue 350Z, the orange 1967 Camaro, the red and yellow Hummer H2, the black and white Porsche Cayenne Turbo, the silver R34 Skyline amongst others. These are particularly rare because they are variants of the Xmods sold in America (or just different ones).
