What would be a good price to install...

Valve Spring Retainers
ARP headstuds
HKS adjustable cam gears (are these needed)
Alcohol Injection

and i'm guessing after it was all said and done I should consider a new tune?

These are the mods on the car right now...

Perrin 3" Turbo Back Exhaust With O/C Vent Silencer
Ultimate Racing Test Pipe
Borla Exhaust Manifold
Buschur Upper Intercooler Pipe, HKS SSQV Bov and Small Battery Kit
Hallman Red Pro Manual Boost Controller
Cusco Oil Catch Can
HKS Grounding Kit
HKS RS Racing Suction Intake
HKS 264 Exhaust/Intake Cams
Denso 660cc Fuel Injectors
Walbro 255 Fuel Pump
Denso IW-22 Spark Plugs
Weapon R Engine Dampner
Tuned by dynoflash..

Right now its making 300WHP and 300TRQ...

I'm looking to up the power safely would this be the best method? And going this route would it be safe to add alcohol?

I am looking for someone in the DE/MD/NJ/VA area I got a quote from TT for just a valve spring / retainer install and it was $1100 which I thought was pretty out there but what do i know...

thanks for all the help!

Your setup is extremely beefy for the mods that you have. You are overkilling it. If anything, you should re-tune the car - you could get to 320 if not more.

 

Thats what I thought, wasn't gonna say anything incase I was wrong. Id just get the headstuds, then tune, then alky if ur not satisfied.
