before i get flamed im new and yes i did use the search button and the sites at the top of the section.


what size are the stock turbos ?

should i get an alluminum ast or should i just ellimiinate it?

can i put a catback on the car without havng to do anything else(like getting a new cpu)?

 

Turbos- Hitachi HT-12s. Not sure of exact 'size' you mean.

AST- Your choice. Cheaper to eliminate it. Some people believe it's there for a reason, others see it as a liability.

Catback- Just bolt it on. Only two more mods, usually intake & downpipe before you need a new ECU.

 

Straight, simple, and to the point. As an add-on to what Sidestick stated, the purpose of the AST is to seperate air from the coolant mixture. The good thing about it is that it allows for more coolant to be added than if it wasn't there which allows supposedly for better efficiency.

 

so both of the turbos are HT-12s?

I already have a dp and intake so will i need a new cpu if i get a catback?

 

(2) Hitachi HT12 turbochargers
Turbine: 51mm, 9 blade
Compressor: 57mm, 10 blade
Curved "high flow" type blades

you don't *need* an ecu for those mods. personally, i would invest in an ECU next however.

 

you dont NEED one if you get just a catback, but i would reccomend it.

HOWEVER, if you plan on doing any more mods at all, you absolutely NEED a new cpu...
