Fuel mods on 12 psi.

Just wondering what sort of fuel mods people here have had to do to run 12 psi (TII)
Thanks.

With a stock ported engine and a stock turbocharger unit, there isn't too much that needs done for 12 psi in terms of fuel upgrades. The stock TII fuel pump should still be fine, but you should probably put in larger injectors. Maybe 720cc all around would be nice.
Don't take this advice to heart though, I'm just giving some general estimations here.

There is other things to consider (ignition, fuel cut defeater, intercooler) but I think you realise that already and just want to know about your fuel system.

You obviously have to have a fcd. I'd say at least a walbro pump, but I'd get 720cc secondaries too.

No FCD needed.... have an N/A ECU! (Conversion)
I can't seem to find 720's around.. there's gotta be used ones somewhere!

Ya there is sometimes. Check on here on the classifieds(or make a wanted post) and on the teamfc3s.org site and www.thepartstrader.com. You'll find some. If I hear of any I'll let you know.

Your gonna need a stand alone to run 4x720's aren't you? And you dont need to upgrade the ignition yet. Stock T2 ignition is very robust and good to about 400 hp

You don't need 4x720cc injectors until you are looking at like 350rwhp and you don't have to have a standalone to run them. You could use an s-afc. 680cc secondaries should be fine, but you never know the condition of used injectors. I bought a pair and sent them out to be cleaned and turned out one had to be rebuilt(which means both so they flow the exact same) and it was going to run me around $350. Thats when I just went ahead and bought some 720s new for like $110 a piece.
