I tell myself it is, but maybe some Billet Axles are on the menu.

I have some head space for more power as well if I ever want it but the 640ish its making now is a lot to handle but I think with a larger A/R housing and potentially larger exhaust it would make north of 700 wheel on E85.

But for now its "done", I need to finish building my house and get my 2.5RS swap started with the drivetrain we pulled from the WRX.

Ha those things seem minor and secondary compared to what you have already done.. All I want to know is the first 2 digits of what you spent on this thing.. It would appear to be kinda sleeper and unsuspecting HellCats wonder WTF..LOL

lol yeah honestly probably talking 30-40k over the 9 years of ownership to get it to where it is today. I bought the car new in 2011.

We were definitely going for a subtle/sleeper build with the hood shut. We're actually working on some blacked out window banners as well for the sponsorships.

This meme summarizes most interactions with "fast" cars lol
