I have been brain storming again and think that I may have found a feasable MFI pump for our beloved TIV 4cyl.
Any interest? |

And they cost something like $1500-2000 to rebuild, and if the space cam isn't right NO ONE can help you fabricate a new one.
The pumps from '69 to '79 US Alfa Romeos would be cheaper and more plentiful, and there are versions with space cam suited to 1.8 and 2.0 engines. The main problem here is they have a huge port on the back that's meant to be open to the oil system on the block, which would require fabricating a plate with an oil feed and a return. Again, no help if there's any issues with tuning the space cam. I like MFI a lot, but it does have some serious shortcomings (like they're all just alpha-N systems, with no load sensing). Now, marrying an MFI pump with full electronic control I'd find VERY interesting. Super high pressure injection for excellent vaporization with no problems handling full sequential injection under all loads. All you need to find is a fast actuator that can position itself to, oh, about 0.005", and can sweep through maybe 0.050" in under 1ms (rough guesses). The rest is easy. |
