do i have to change my fuel rail to fit 550cc injectors on a 99 uk turbo?

also, fueling wise iv got a walbro..will 550s and walbro flow enough fuel for 350bhp or will i need a regulator also?

 

Not if you get the correct injectors.... and sorry no I don't know myself !

For 350 bhp you should be o.k. without an FPR, I have one but that's to stretch to 400 bhp !

P.S. get some new seals, and "lube" them when fitting, to avoid leaks....

 

Phase 2 550cc will be a straight fit.

Fuelling whise 350 on 550cc will be fine.

 

thanks boys so il reg away without a regulator, or would i be better with one?

 

No need, as stated above raising the fuel pressure just allows you to get a bit more fuel into the engine. Mine has had the fuel pressure tweaked by 0.5 bar as an alterntive to larger injectors to (hopefully !) make it into the 400's.

P.S. a dyno run will identify any fuelling problems, AET at Castleford have an offer on till the New Year.

 

i cant afford to finish mine off by new year but hopefully gonna give andy a ring and have it mapped up there

cheers boys
