Hi,

I believe I may buy both of these kits together second hand, as it will be a large saving and it's what I am considering using it all comes together, i believe it was originally purchased together but I can't find it as one item.

Either way, would this be able to take a 10PSI turbo? I see the fuel pump supplies plenty of pressure... 30 - 70PSI (I thought it was only supposed to be 5 PSI, or is that just for carb applications?) Additional to this, will this work with a stock 225? I wasn't sure again with this fuel pressure, I'm hoping it is somehow regulated?

Kind regards, Ben

I wouldn't use that on a boosted engine; it's really intended for mild crusing applications. FAST's EZ-EFI uses a MAP sensor won't read boost, and there's no good way to change its settings to tell it you have a 2 bar MAP sensor. I would also have some concerns about fuel distribution issues with a TBI under boost - throttle body systems tend to have worse fuel distribution than port injection, and forced induction is less forgiving of leaning out a cylinder. If you specifically want FAST, the system you'd want is their XFI.

Thankyou Matt Cramer, I was able to email them and they agree with you, I was hoping this would suit as it looks like it will be around $1000 on eBay...

Perhaps someone else may find it useful I'm not sure.
