I was reading some of the recent threads with some engine mods and a CL ad with an incorrect picture of a 6 cyl motor (but the cylinder spacing was pretty close) and it all reminded me of some of the things I've read about in the early days of hot rodding. Those guys would dive in and make parts or make major modifications to achieve what they wanted. Hacking off half the cylinders of an engine or grafting 2 engines together wasn't unheard of. So the question that comes to mind is, since the 4 cyl uses the same piston, does the head use the same, or nearly same bolt pattern? Could the 16 valve head bolt onto a 3 cylinder block? Will the vital passages line up? If they do, has anyone tried hacking off the end of the head and having the cams machined down? I'm sure there is probably an issue with the cams that makes it very difficult to pull off but I haven't looked at a parts breakdown to see how the end is put together. Of course as far as that goes, someone with some mad machining skills needs to graft two 3 cylinders together into a V6 just for the totally cool factor. |

Had an old man tell me one time he fixed a straight 8 cylinder on the side of a road that had a rod bearing go bad and he used his leather belt for a bearing !!!! Anything's possible .... |

Cams couldn't be just cut off, as they'd have the wrong timing. You'd have to get completely new cams designed. There already is the K10, a Suzuki three cylinder with four valves and twin cams, might be better off trying to use parts from that, or the whole thing. |

Anything is possible! Not a Geo, but still: http://www.hondatuningmagazine.com/tech/1307_reverase_head_h22_conversion/viewall.html How much time do you have? |

Yeah, now that I've had some sleep that is pretty obvious since there would be a gap for the missing cylinder. Lopey idle anyone? Since this was not listed as a budget thing, getting a K10 for a swap might be a good solution to the idea. I'm guessing it's an overseas motor, what was it available in? (I suppose I could google, but conversation is fun). I currently have no way to afford to do any of it, it's just an interesting question to explore. |

Almost none!! More of a random idea that I was curious if anyone had explored before. |

K10B is sold today in most of the world, comes in the Alto and the Splash, the two models smaller than the Swift that the rest of the world gets. |

Impressive creativity and workmanship! Being completely unencumbered with detailed knowledge of the topic, let me ask the question that springs to the front of my mind. ![]() Assuming that a reverse flow is good for the reasons detailed in the article, in the case of the Metro G10, wouldn't it be easier to just do a lot of head work and porting and make the exhaust side of the head the new intake side, running the exhaust out the back where the intake plumbing is now? Of course, you'd need to switch the intake and exhaust cam lobe positions on the new custom cam, too. I don't know what other details would have to be taken care of, but the cam sprocket would still be at the right end and you wouldn't have to worry about lining up oil and coolant passages. Everything on the engine would remain the original design, but the head, cam and manifolds would be unique custom parts. I tell my students that all you need is time and money and you can do anything ... |
