Howdy doodey fellow peeps, i been workin on a intercooled m90 install on my falcoon, eventually ill be running 12psi megasquirt, 42lb injectors and walbro intank but i seen this turbo kit on ebay http://item.mobileweb.ebay.com.au/viewi ... 8581926733 and noticed hes running 6psi with no tuning and no other upgrades except a fuel reg.

Now my question is if i purchase a 6psi pullet for the time being would i be able to just upgrade thw fuel reg and leave all else alone and just slowly upgrade as i go running 6psi and just a high pressure fuel reg oh its a ef sohc engine

IMO adding boost with no options to change fuel and timing is going to create problems. If you take it easy on the throttle you might get away with it. What fuel reg are you planning to use? I think someone mentioned using an AU fuel rail with a BA XRT fuel reg.

Im not exactly sure what fuel reg if i go 6 psi at first, thats another thing i was going to ask.

Once the 12psi is going ill be running a 12:1 rising rate fmu but yea it only got me thinkin cos the whole blower kit is ready to go i just need the fuel side of things but if i can run 6 psi with just upgrading a fuel reg like this guy reckons he can do with that turbo kit in the link ill be able to bolt it on now and then once i got the fuel system i need for the 12psi ican change my pulley over n im sweet

I bought Troyman's Raptor SC and still haven't got around to getting the car on the road. I bought a 12:1 fuel reg to go with the SC but the tuner, I use, said he can adjust the fuel using the J3 chip. Hence, I'm now using an ELXR6 fuel reg, and changing to 26lb injectors when I get the car on the dyno. Are you planning to use a wideband air/fuel gauge?
