New to4b vs rebuilt hybrid and fuel upgrades
 
I'm considering one of two options at this point.

I'm either going to get a t04b Hybrid with my s5 turbo, or a new t04b from fc3s.org.

The price on each is about the same (after getting a new manifold, then getting a downpipe made for the t04b it's still pretty close).

The main question I have is, If I get the t04b, I'll have a walbro and a S-AFC for fuel mods. Is it ok to only upgrade the injectors to 4 720cc injectors and wait for a standalone? I'd like to do it this way so that I can get the standalone later when I'm ready to drop the money for it and really go crazy with boost.

If I went with a hybrid i'd still be limited to under 15psi.

turbo + manifold + downpipe + custom oil / water lines + wastegate is ALOT more then a hybird....

you'd never run more then 15psi on the to4 either...

yeah i wasn't considering the price of the wastegate or the lines.

Dave claims the turbo can handle 30 psi...

Take a look

ya but nothing else will...

15psi on a full to4 with everything else good is over 400RWHP...

What's your power goals? How much money can you realistically spend?

If you go the full t04 route, just keep the stock turbo on until you can afford to upgrade the fuel system and get a stand alone.

Well I've got about 2 grand alotted for it realistically. My turbo is undriveable. I figured I could get a to4b and keep it at low boost till i can afford the stand alone. I can do turbo, manifold, lines, wastegate and injectors... but not a standalone.
