Irrelevant. It's not like you plan on slapping a turbocharger there without modifying the intake right?
Re: Lancer EX
Although I'm generally not a fan of the 1.6L Lancer, there's cost-savings to factor in too which you can then divert to modifications. I'll still go for the 2.0L and then turbocharge that. Sometimes, nothing beats pure displacement
You'd also want to upgrade your brakes ASAP to take advantage of the added power.
Re: Thread
Personally, I'll cast my vote with a Fiesta. There's a ton of modified Fiesta making rezing-rezing on track days. Aside from being a joy to drive thanks to its stiff suspension, you also have weight reduction savings compared to that of the EX.
