I haven't committed to anything on whitey's conversion yet...and my mind started to wonder. How 'bout a water-cooled Porsche motor? I've looked, there are a lot of choices available right now.
- 0 mile 2004 911 3.6 replacement motor (315hp) - 18k mile 2002 911 3.6 (320hp) - 34k mile Boxster S 3.2 (250 hp) - 39k mile Boxster 2.7 (217 hp) (prices vary from 4000 - 12000) *hp numbers from Kelly Bluebook dot com also - Boxster S 6 speed trans (bad 3rd gear) - Boxster 2.7 5 speed trans (40k ish miles?) I know we've discussed this before - and I KNOW there are issues. Something about rear suspension relocation...but can't remember the details. What about computer issues? Heat? I should be able to do modern heat, right? Exhaust - A Cayman or Boxster muffler? Custom headers (probably a must?) or maybe Cayman/Boxster headers? with some tweeking? I know there are more issues, and definitely don't know the answers...can we get a good discussion going on this topic? TIA -the dreamer (IMG:style_emoticons/default/biggrin.gif) |

Sean,
Stick with aircooled for a 914 conversion project. There's too much Star Trek (going where no one has gone before) involved with a 986/996 engine swap for not enough benefit. If you get a good 3.2 you'll be a very happy man, and it's been done so many times it's a bolt up deal without much custom fabrication. |

Sean, Stick with aircooled for a 914 conversion project. There's too much Star Trek (going where no one has gone before) involved with a 986/996 engine swap for not enough benefit. If you get a good 3.2 you'll be a very happy man, and it's been done so many times it's a bolt up deal without much custom fabrication. Much as I like the idea of a 2.5 or 2.7 from the 986 in a 914, I have to agree with the above. And I'd rather try to take a 986 down to 2,500-2,600 pounds than to build a 914 up with a 986 engine and radiators, etc. Getting down to 2,600 in a 986 wouldn't be easy, though. With a half tank of gas, mine weighed in at 2,911 or something similar, with heavy 18s. Sounds awful, but it was only one pound more than a 1989 911 coupe on Fuchs 16s... (IMG:style_emoticons/default/idea.gif) Really makes me want to weigh my 914.... You could probably drop 100 pounds from a 986 between GT3 seats, carbon lids, lighter wheels, and a light muffler. After that, A/C delete would get you ~45 pounds and then you'd be getting into stuff like trunk trim delete, sound deadening delete, and more. Which gets you back to 914 3.2 air-cooled for those perfect days, and a stock 986 for the rest of them. pete |

You could probably remove all the hardware for the convertible top on the 986 and only drive it on perfect days. |

You could probably remove all the hardware for the convertible top on the 986 and only drive it on perfect days. Looked into this when we were working out our "Spec Boxster" Tech Forum. Apparently, it's only 30 pounds thanks to a *forged magnesium* top frame. What's more, the motors weigh almost nothing (six-ish pounds). 30 pounds might sound tempting, but you lose a major chunk of what makes the car great and usable. And the factory aluminum hardtop weighs 45~ pounds... I'd rather ditch the spare tire and jack for short trips, which has gotta be 20-30 pounds, easy. And then go after sound deadening and the stereo. Another way to go would be gutting the doors and making up some plexi side windows with simple guides and leather straps to keep them up. Or maybe GT3 RSR doors with the same adapted? Getting pretty "hard-core" though... Also raises safety concerns. (IMG:style_emoticons/default/idea.gif) Then there are ultra-light Wilwood calipers and lightweight rotors... CF wheels, etc. But the $$$ are starting to explode. Fun to dream, though. Solution? Trick 914-4 or 914-6 and a stock 986 or 986S. pete |
