Hi guys, I'm a newby to Scoobienet, and would like to get some opinions about the best turbo upgrade for my car. It's a JDM '04 STi, with the 'short engine' replaced by the crate Cosworth 2.5 unit, so it'll take the power, and I'm running it with a front mount.
The car is my daily driver. No drag racing planned, but maybe a track day or two. It's primarily a road car, so needs to be well mannered around town, and I want as little lag as possible, with boost coming in at the lowest RPM possible. Looking to acheive 460 -470 bhp, with similar torque. Was thinking about the MD555, but am open to suggestions. Comments from any member who has experience with this problem would be welcome.
Cheers!

Have you still got the twin scroll setup or single scroll?

Cheers guys,

Greg and Mike - is the SC46 a twin scroll? It doesn't list twin scroll as an option on anything past the SC42 on the Scoobyclinic website.

Aladdin - it's still running the factory JDM turbo, the IHI VF37, a twin scroll unit. Really punchy, Bob Rawle mapped it, and it's great, but has its limitations as regards power, and runs out of puff at higher revs - made even worse since I had the 2.5 conversion.
