hi, im going to upgrade my turbo to a t3/t4 hybrid and i was just wondering if i need to buy a safc or something to control the fuel, or if im going to be fine without any safc or something to control the fuel. im going to be running at 12 psi.
(my mods are,racing beat complete exhaust system, racing beat alternator and main pulley, and a turbosmart bov)

thanks

 

First of all you need FUEL upgrades:

injectors
pump
fuel controller
FCD

 

You should look for some 720cc injectors for your secondaries, which you might find used for about $100 bucks. Then you'll need the S-AFC to control those since the stock ECU won't know what to do. You can get that for $250 used/ebay. The fuel pump you can either upgrade to the FD pump. Most people go with the Walbro 255. The FCD you can buy brand new for $100 which is outragous. I got lucky and found one for $45 bucks. You could also make your own. www.fc3s.org has schimatics for that.

I went with the hybrid... Very nice choice to go with!

But yeah... fuel upgrades are a must.

 

do you have a s4 or s5 t2?

if your looking for 720cc injectors i have 3 left for sale.

if your working with a S4 go with a Rtek chip http://www.pocketlogger.com/
