So I have an evo 8, with about 54k on the odo. I only ever did some modification in my 240 when I had it but not much so I am still trying to learn..anywho. Right now my car is running at about 325awhp, my goal is to try to get it to 400awhp. What mods would you support? As well what kind of price range am I looking at for that type of gain? I looked around a bit and like aftermarket cams, intake, evo 9 turbo, new clutch...

P.S Keep in mind I am still noobish so abbreviations will melt my brain for now lolol.

P.P.S These are my mods, for the most part lol.
- Full Turbo Back Exhaust (Megan Racing 02 housing and downpipe, Perrin catalytic converter, Greddy Ti-C CatBack)
- intake (Perrin washable filter, Buschur Racing intake pipe)
- manual boost controller (Hallman Pro)
- upgraded intercooler pipings (Extreme Turbo Systems)
- new clutch changed Sept09 (Exedy HD Stage One, good upto 400hp/tq)
- Walbro 255 Fuel Pump
- Girodisc Magic Brake Pads

 

1000cc injectors -200-300
E85 tune with tscompusa price : 100-200 dollars.

Done son.

 

Stupidness was posted here lol.
But what is an E85 tune? Is it just a specific tune?
