Sounds like we need a bi-turbo set up with one small for low end and one big for high end....

 

That increases cost and isn't that efficient on such a small engine.

 

Ok how about a higher displacement 2.4L 4 cylinder with a bigger turbo???

 

Higher displacement (Subaru, Mazda, Dodge), twin-scroll turbo (Evo X has this), aggressive cam management (Evo IX), or direct injection (VW, MAZDA), are all ways to go. Twin turbo makes more sense on 6+ cylinders. Subaru tried it on the older Legacy GT's being they could bank the turbos off of each side of the heads, but still used a single throttle body. The turbo change-over was a big down-side to these, and a bigger single turbo was the tuners choice. The twin-scroll replaced that concept, and has stayed as the alternative to having *effectively* dual boost characteristics...

...the best thing to do for the RA is to put the Evo's turbo on and get a safe tune. IMO.

 

Subaru already uses a 2.5 L. A bigger turbo would increase lag.

 

Can't think of any USDM twin-turbo 4-cylinder cars. I know there was a bi-turbo Legacy somewhere along the line, but of course it was a JDM-only item.

EDIT: Didn't read RS-0's post before posting. Oops.

 

I think people should just wait to drive it before they suggest all these upgrades.

 

Agreed. I think a natural upgrade would be along the lines of the Imprezas-->STI turbo swaps. The Evo comes with a good turbo, and by using the smaller stock RA front mount, lag *should* be a good 250-500 rpms lower than the Evo. Peak power will be lower, but the trade-off might make for one quick car...

 

I just stopped at the Mitsu dealer today. Early October for their first RA's.

 

BOOOO!!! How about for the Sportback??

 

But then how would we speculate on how much power it'll make once the GT35R kit comes out, and how well the paddle-shifted 5-speed will hold all that power? Buzzkill.

 

Lol I almost forgot about the infamous paddle-shifted 5-speed. Speculation is fine, I just find it weird that people are talking about having to swap turbos or increase displacement before they've even driven the car.

 

I'll take my paddle-shifted 2.3L GT35r'd Ralliart with a full Evo body conversion, a 200 shot of nitrous, Brembo Gran Turismo brakes and race slicks, please. Oh...and I want it resprayed Phantom Black.

 

Lol, something tells me that'll remain a dream for some time.

 

Don't you know? "Some dude" already has one. My friend's grandfather's son's daughter's brother told me all about it. Supposedly it eats Veyrons for breakfast, and picks its teeth with MS3s.
