rolleyes.gif just got my turbo and manifold setup, its a t2 turbo from a dodge daytona with about 80,000 miles on it. I am using a hf manifold with a plate.
before i start on hooking it up, i need advise on fuel management.
would using bigger injectors and a fuel pressure regulator be enough
to keep it safe?
do i need some other things like a fuel management system or modified computer?
it will be a daily driver and weekend dragster!

also, would i need a new fuel pump or larger fuel rail?

please help

what engine is this?
If its a stock d15a3 I woudl recomend 450cc injectors and a SAFC or SMC-500.
Fuel pressure regultor wont do much, a FMU woudl work though if you want to go cheap. It would raise fuel pressure to insane levels and keep the car runnign rich.

how much do fmu's usually cost? and how would you be able to make sure you have the right mixture? can you have too much fuel?

The FMU makes the car run really rich on idle... The one you need, if you're going this route, is
the Vortech 12:1 FMU. This is what we ran last summer on the ZC and it served us fine. Now
that we are going with Turboedit, we no longer need the FMU. I put it up on ebay so it's forsale
if you need it ----> (sorry for the plug but here is the link) FMU auction
