As another original-6 owner (who admittedly, has never driven a 4)... the sound is the thing... My '70 didn't (and won't) have any sound proofing betwixt engine bay and people bay, so if I ran open headers and free flow aircleaners and then the chains themselves added to the din.. (not HP, though...) the drive was heaven... And the responsiveness of the small 6 is something else again.... not too much for the factory suspension and gearbox... but plenty enough for fun....

I'm sold!
Told you it would be easy! If I don't like it ( is that even posible ) I'll just buy another car and start over with my stored 2.0-4. (IMG:style_emoticons/default/idea.gif) I guess somebody would buy my car with all my upgrades for $8-10K (IMG:style_emoticons/default/confused24.gif) Or have two 914's ( 914-6 baja...Why did I just say that? ) (IMG:style_emoticons/default/lol2.gif) I'll start next week. I already ordered new plugs, wires and coil. As for exhaust I'll start with a heatless header. Possibly modify the Tri-Mil Supertrapp I already have into a mid-engine under car instead of the baja tee-pee thing. This will be fun. Thanks for all the help 914club!

A 2.0/6 from a 914 IS a waste of time....IF you are doing a conversion.....
HOWEVER.....a 2.0/6 "S" motor is 180 peaky HP....which has been.... so far ...... a kick in the ass.... (IMG:style_emoticons/default/mueba.gif) |

That's what an "S" motor is rated at....

Z... did you buy your 2.2 in Frankensteen from Sager/Kravig at the last 914 swap meet? If so, that is probably the one that came out of my car. And yes, it was a peaky, screamy, adrenaline-soaked, ass-grabing-the-seat motor in a 914.
The 2.7 is a different ride. It motors around town feeling like a 2.0 T IV when you feather-foot on the idle jets, then just melts the tires and disapears over 4000 rpm when the mains kick in. Makes me wonder what a built-up 3.8 Euro RS would be like (IMG:style_emoticons/default/idea.gif) |

Mike,
is it an aluminum cased or a 69 mag cased 2.0 S motor? I think the 69's were rated at 180 but the increase was due to the mechanical fuel injection in 69... I thought you were running carbs? the common thought is the 67 S motors were rated optimistically by the factory at 160hp.... I have a 67S motor going into my vintage car. just curious because I'd love to learn more and hope that the 160 rating I have is legit... brant |

I bought BOTH motors from Glen Sager.....the 2.0 was an S motor but the specs aid it was the model that came with Webers.
On the 2.2.....did you run a CDI with it? I just got it running and it runs a little rough.....I'm thinking the jetting is off as I have carbs on it from a 2.4.....got any specs or suggestions for jetting? |

MSD box. The carbs wound up on my 2.7, after a venturi change to 34 and major jetting work. The cam in my motor is a more for torque that 906-ish peak. Not sure what the jets were on the 2.2 as they came with the motor. The secret is locked up in Kravig's head. (IMG:style_emoticons/default/laugh.gif)

Hey, I realize its probably too late, but dont do it. True, a /6 is a great sounding, and even with a 2.0, a reasonably quick car. But, notice how your FI /4 starts right up, even on a cold day? Not so with carbs. And how your FI /4 drives and responds under all conditions? The carb'd /6 will run crummy until its warmed up, and even then never as well as the /4. And thats the best you can hope for. Lotsa luck if the engine and/or carbs aren't happy, or if something has been done to that engine that the carbs dont know about. Or vice versa. Also, expect about 22 mpg vs. 30 for the FI /4. A car that doesn't run well will get old fast.
Not to mention the cost of parts and labor. And emissions testing, if applicable. And how about the quality of the work? Will it look like something that has come from Porsche, or some hack job replete with cheap crap from the local hardware store. Is your /4 running now? Do you really want to fix it if it ain't broke? Knowing that the time and money spent will not be recouped if sold? Hopefully food for thought. |

QUOTE(trekkor @ Jun 3 2004, 08:54 AM) No one has said "Hey, bro, I've got a small six and it rocks. It is so much better than that fuel injected 4 I had. I really love the way it winds up and gets me going" Is that because the small six is garbage? (IMG:style_emoticons/default/confused24.gif) Let me help you out. I have a small /6. I believe it's basically a stock 2.0. It rocks. I love the feel, I love the sound, I love the Webers breathing behind my head. I HATE fuel injection. I HATE wires, tubes and vacuum hoses all over the engine compartment. It looks like an Intensive Care Unit setup for a dying motor. You CAN be happy with a small /6... I am. -Rusty (IMG:style_emoticons/default/smoke.gif) |

(which is not stopping me from looking to uprate the 911 to 2,8 tho ...) |

Z - I think you'll certainly want a Bosch CDI or aftermarket (i.e. MSD) with that engine. All of the factory high-performance engines had 'em, IIRC. It should help with the low speed plug fouling and idle to main circuit transition, but don't expect miracles as even with perfectly jetted Webers or MFI these engines are just kinda "bitchy" at lower rpm's and/or when cold.
What jetting do you have now? My carbs were fairly farked up and I set them up to 2.0S specs (except F26 emulsions vs F3); much mo betta now but I may need to bump to 60 idles. |

Yeah....I spoke with the former owner of the 2.2 that's in Frank....I have six or seven oem Porsche CDI boxes that need some repairs.....my neighbor has the parts at work and I have a copy of the Porsche schematics for the three prong series, so we will rebuild them....also have a fireball ignition system from the Type IV and a Crane type CDI box....will look thru the schematics and see which is the most idiot proof.... More welding this week on the pans....then install the seats, replace the leaking exhaust gaskets and take Frank out for a spin.... |

Once again I'll say if you are gonna do a conversion, just drop a Small Block chevy in it..
Easier and cheaper to repair than a six.. You can get 300 HP and never even try to do so! Just bolt it together. Hell all the parts can come from Summit! TIV, or V8 if you ask me... |

I have a 2L 6 that has been sitting for 8 years. I never had the money to install into the 914. I do have a 2533 4 in there now. I love the sound of my six in the 911 but I also love the sound of the 4 when I am passing guys with big V8 muscle cars. I love the big four. Just my feeling. If you want to go big talk to Jake on the four. Good luck with the 6. Thanks Mark

Did some work to get ready to run the six. New plugs, wires and coil.
Found an oil tank ( under the cushions of my sofa ) and had some oil lines made for testing. We're shooting for a monday fire up! (IMG:style_emoticons/default/cool_shades.gif) |
