All this talk about converting the G-10 to MPI is great; I wanna hear more! The fact that the injector bosses were cast into the head was news to me. So consider this; the big problem with the original intake is that you have 2 long runners and 1 short one. This is why you don't many inline 6 cylinders anymore and the ones that are still around {BMW, Jaguar} are all mpi. With a single TB or carb on top the stock manifold you get a richer mixture to that center cylinder witch builds carbon under the rings and eventually renders them useless. What we need is for someone like MM Products to build us a Dry manifold with equal length runners designed for MPI to include of course the EGR so that we don't overheat the pistons. MM already builds a header how much harder could it be to build a tubular intake? |

this build used a canadian market only turbo3 intake manifold which is completely different than the normally aspirated g10 intake manifold. the turbo3 manifold has a side mounted throttle body, has a true plenum, and utilizes equal length runners. the injectors are fitted to machined holes over the intake ports and are held in by the physical mounting of a fuel rail. |

I would love to see this on my n/a.. boost would be nice but i wonder what numbers you could bring from the manifold/ ecu / cam / and built lower end. keep the 45 + mpg but bring around 70-100 hp from the n/a 1.0.... I cant wait to see tofuball's geo mpfi

I haven't touched the car. I'm probably never going to get around to it. I should just sell it. Want it?

No!!! I badly want to see what kind of fuel mileage is possible out of a tweaked Megasquirt G10. Would love to do it myself but I'm too much of a dummy.

Yeah. I'm doing the heater core in my wife's car. It's cold in the garage. I'm alone. No torx wrenches, lost in the move. Building motivation to go out again. Besides music, I watch Ironman 1 for a little inspiration, sometimes.

![]() That's wonderful logic. If Tony Stark can build the Mark 1 in a cave, from scraps, just imagine what you can do in your garage!

every time i venture into the realm of "where no one has gone before" i get cranked up. there's nothing like a challenge to engage the old noodle. i've had to dope out a lot of stuff on the megasquirt and turbo3 projects. i'd be happy to help you brainstorm if you'd like. i worked out the timing basics for sequential injection and 3 channel direct ignition so you wouldn't have to re-invent the wheel on that. the last time i looked, you seemed to have all of the mechanical stuff worked out for the conversion from tbi to mpfi. |

Yeah, you're right We'll see what happens come decent weather. I do miss the XFi MPG. Took this picture a few days ago for you guys in my daily driver: ![]() Traffic around here sucks. Edited by Tofuball, Dec 23 2013, 02:15 PM.
