Hi guys,

Thinking it's going to be time for my second round of upgrades for the 08 WRX. Big service coming up so I figure I'll give myself something to smile about at the same time.

Have done wheels, suspension, exhaust and initial tune already and now going to go for some more power. Ideally I'd like to have 270-300whp with a good torque curve and nice response. Best of all worlds basically, but I'm sure I'll have to compromise somewhere. Also thinking of going E85 since I have a United that sells it about 10 minutes from my house. I will go through ASG for tune.

Budget for parts and tune is going to be around the $5k mark with me planning to fit parts myself.

Shopping list so far:
DeatschWerks DW65c Series Fuel Pump ~$160
DeatschWerks DV2 Fuel Injectors Top Feed 1200cc ~$800
GrimmSpeed Boost Solenoid ~$140
Perrin black TMIC or Process West TMIC ~$1000

That's the extent of my supporting mods at the moment. Is there anything I have left out, should I be considering a CAI or anything like that as well?

That list so far leaves about $3k for tune and turbo which should be about right. I'm at a loss as to which turbo to go with at the moment. VF52 seems to be the easy swap option, but it also seems like I could or should go something beyond that since I'm forking out to upgrade in the first place. Maybe a TD05 18g? Definitely want some good mid-range and top end but don't want to sacrifice too much low end power for it. I'm sure E85 will be able to help with that. Any advice on what turbo I should be looking at?

Thanks for looking and appreciate any help I can get.

TL;DR
Want more power, how does my supporting mod list look, and what turbo should I buy?
