Putting a 1JZ in my car, and have just had a bit of good news that means I *should* be able to fit the factory twin turbo setup.
The engine I have fitted doesn't actually have anything on the exhaust side. I was going to run a custom manifold and CT26, but now am making some changes which should give room to run the TT setup. Through a friend I have access to a setup with one blown turbo, and was thinking that this might be an ideal opportunity to hiflow the turbos for a bit more power (obviously steel wheels for reliability).
After a bit of a search, no real results can be found. It gets mentioned a lot, but most people are just throwing the idea around rather than commenting on the results.
Has anyone actually done this, or know anyone who has, and do you have any info regarding the results of the upgrade? Don't really want to do it unless it's worthwhile... and please don't suggest a big single as I've decided against this idea due to cost.
