2.7 CIS.... (IMG:style_emoticons/default/driving.gif)
Thats what I have. lots of power, era correct, and the sixes sound great at 6k rpms. Mine has been really reliable and gets 23 mpg (town and freeway). I would assume building a 180-200 hp 4 cyl still costs about 60-80% of a six... maybe someone will chime that knows... |

Well... http://forums.pelicanparts.com/showthread.php?t=394159 My motor only cost about $2k and I have been running it for 8 years, but it always has been leaking oil , then we spent another $1.5-2k on parts (oil tank, oil Lines, throttle cable, motor mount, fuel lines). So about $4000, but I've gone back and replaced wear items such as the clutch and chain tensioners. I guess the key is find an inexpensive good condition six to run. |

You can do a dirty conversion for under 5k. A 2.7 with CIS could be nice, but you would need to decide if you really want to go the six route or stay with the four. Once you start to go for a six you start adding stuff that is difficult to un-do... like the correct engine mount and oil tank. I am going for both. I want to finish my six and then I want to buy a four shell to prep it all purdy like to drop a monster Jake Raby engine in it.

I'm not a concourse weenie, but I prefer the motors porsche was using when they made our cars. Small displacement, light weight, mag cases, rev happy motors. I'm going to be building up a 2.4 with 2.2 'S' pistons and mod-solex cams (halfway between E and S). But I'll be using TWM trottles and megasquirt for a modern twist!
Does anyone here have corner weight numbers on their 3.0 or bigger conversion car? How much did it end up weighing? I'll also be driving my totally stock 1970 1.7L Tangeriner around while I'm building the six. I like em all. dug |

I weighed mine it was at 2250 lbs w/o driver and 1/4 tank of gas.
According to: http://www.penaltykicker.com/911/data/Weig...20for%20911.xls The 3.0 is only 21 more lbs, putting it at 2271, with everything in it (seats, door panels and I think a bolt in roll bar) FYI.. it was a car balance beam scale that sits outside of the sacramento dragstrip, so i'm not sure how accurate it was. |

3.2 short stroke w pmos no cutting no fandgeling in the engine compartment and retaining a stock sixish look i think a raby engine would be my second pick |

When I looked at a kit, it was between $5-$7k (depending on what you wanted e.g. 2056, 2270, 2316, carbs, FI, etc.). A Tangerine exhaust added about another $2k. So, about $7-$9k. When done, brand new motor. I found a 3.2 w/ approximately 4,000 original miles on it for $6k shipped. Figure another $3-$4k for the conversion parts and am at $10k. When done, a used motor (albeit low mileage). YMMV |

BTW: 2000lbs / 300 hp = 6.66 lb/hp <--- Thats pretty damn good (not like you didn't already know) Another thing I forgot was that my weight was with the old '75 bumpers. Thats probably like 100 lbs... |

Like Andy I went with a 95 3.6. These are great engines that don't need to be pushed hard to deliver a fast ride. The 95 and earlier non-Vario-Ram engines are OBD-I electronics that do not require a re-flash to operate in our cars. Also, 95 has hydraulic lifters READ: No valve adjusting!. A re-flash for 96-up is about $1000.00 if you go that route and like Andy said the Vario Ram won't fit right anyway.
After going through the entire conversion process my recommendation would be as follows if you go the six route 1. Buy the cheapest engine you can find that's decent and rebuild before installation. 2. Get a 3.2 or a 3.6 with modern electronics. 3. Have a LARGE pocketbook and be patient. There is a lot more expenses for doing a six and it can easily spiral out of control if you are not careful. Is it worth it? I think so. (IMG:style_emoticons/default/w00t.gif) BTW, my car weighed 2200 with 1/2 tank of fuel, spare tire and two sacks of concrete on the drivers seat during corner balancing. No effort was made for lightening the car but it has fiberglass bumpers and early light weight doors. |
