$1800 is a lot but your ass hurts if you think a VF52 can come anywhere close to a AVO380 out put. ralliteks stage 3 puts out 375HP 440TQ on E85 and 22psi. and all it comes with is the turbo, fuel pump, injectors, TMIC, intake, and not needed inlet tube. yes it has TBE but no headers, no EWG, ect. the most ive seen a VF52 do is 320-330hp. theres a good 50hp difference if you did both on the same dyno with same parts. 22psi is also conservative. push it to 24-25psi on E85 and ill bet it breaks 400HP.
Scott-2011 WRX 335HP 394TQ 93 VF52!
