Ok, just a quick question.....
Would the CIS system off a 2.4T work on a 2.0S engine? Are the cams so different that the "flapper" would bounce and cause driveabilty problems (not that the S motors don't have them anyway)? Now's yer chance motorheads.............. |

My guess is no way. The S cams are very wild, and CIS really hates wild cams. It would idle very badly, and have really crappy low end.

S cams won't work with CIS...too much overlap

The carbs that came with them I would suppose..... One site I visited for "S" motors recommended that you carry a spare set of plugs as they would foul in traffic at low RPM. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif) Thanks for the answers guys.....it was what I expected, but I'm no expert on /6 motors. Whatza matter Aaron...you don't want me to cream you with a 2.0S motor? (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) It might fit real nice in that flared roller you have (IMG:http://www.914world.com/bbs2/html/emoticons/unsure.gif) |

MFI is pretty major money. Rebuilding the pump runs about $1500, on top of sourcing the pump, the throttle bodies, the injectors, the plumbing, etc. Carbs also aren't cheap, at $1500 or so a set for used ones. I don't want to know what PMO charges for a new set. For PEFI, however, you can use TWM throttle bodies, and get the same look and sound of Webers, but they won't foul plugs constantly. Webers on an S motor have to be set up pretty rich to have any drivability at all. PEFI could be tuned much better. This is still not a cheap option, but you'll get better drivability, and it would be cheaper long-term than MFI. |

Yup, if you start out with MFI it's worth saving or keeping up on it. If you don't have it, carbs will do 95% what MFI will.
Hey Allan, remember those carbs are 46's and that engine pulled 155-160 across all 6 cyl's so yeah, it sucks BIG TIME! (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) |

Pre74 S cams are one thing , Wild (IMG:http://www.914world.com/bbs2/html/emoticons/mueba.gif)
74 and later US car S cams are designed for CIS |

PMO's are $3500....I think that's Canadian $. A 911 guy had a set at the PCA show, very pretty but at that price tag I'd take the PEFI. |
