I should have saved the 2, 2.4 engines I had. The MFI could have been reworked for less than what it costs to purchase that stuff now.
I was trying to collect enough parts to try a short stroke ST spec build. 66MM crank 89mm P&Cs 10.5:1 Elgin Mod E Cams twin plug 46/40 heads High butterfly MFI Would have been a screamer. But, alas... I ran out of know-how and flipped it all for the 2.7 I am building. I know enough now to lose sleep over it but not so much any more. |

Have a 2.7 with some work that revs to 8000 rpm. Just amazes me a old 911 motor can rev that high.
Makes decent power but once you get above 6k it just rockets like a beast. Now that the transmission works right I can keep it in the power band really easy and get myself into some real trouble. (IMG:style_emoticons/default/driving.gif) |

Dan,
Since you are so close to my house you are welcome to come by and take my 1973 MFI 2.4S out for a spin. I am at Camden and Blossom Hill. (IMG:style_emoticons/default/driving.gif) Here is some of my favorite info from google books...Pg 108 - 112. Click on contents, then on pg 113, then scroll back to 108 - 112. This has great info on the older engines. Linky. |

Thanks Michael....
over the years of instructing at AX and DE/TT I have driven just about every size 4 and 6 Porsche ever made, including 4 cammers, 2.0L S motor with 906 cams and a few other fairly exotic builds. 2.7RS motored 6, 2.5 twin plug, 2.4S, 2.2E etc. I have a pretty good idea how one would run. Just thinking out loud... (IMG:style_emoticons/default/smile.gif) |

For years I dreamed/planned to build (er, have someone build) a really hot twin-plugged 2.5 SS MFI or slide-valve screamer. Time, money and opportunity converged and I ended-up with this carbed 2.7, which I am super happy with although I still think MFI would be cool. It has the pump drive cams and injector ports but I just do not see going to the expense and trouble at this point, unless maybe my Webers totally crap out somehow.
