http://i854.photobucket.com/albums/ab10 ... ngine1.jpg This Datsun six looks a lot like a slant six. The shiny parts are pretty, but something less costly might work on a slant six with the Aussie Speed M90 Supercharger manifold. I am a cheapskate - I won't be doing this, this ought to work just as well on the slant six. |

This has existed in my mind for several years, and I have an M90, but it has not happened.... yet... Nice pic! Lou |

I have even gone further, designed the manifold, mocked it up out of plywood, tried twice to build it out of aluminum, next time it will be mild steel. Designed the pulley setup and mocked it up. Tried the plywood manifold in my '65 and found that wouldn't fit that chassis. The inlet would be to close to the master cylinder. On the other hand it will work in my '73. One of these days it will run. |

That is beautiful. I was wondering where the battery cables were?  This is one of the few in line sixes of relatively modern ancestry which has intake and exhaust on the same side of the head. AT least of the ones I have seen. The BMW I guess was the one seen most often, as most others have moved to V designs.Sam |

The Datsun L series heads have raised intake ports, I wish that the slant six had that feature. Its costly to build one of these Datsun sixes more than 3 liters. I think the slant six would do very well with the supercharger! |

I had the chance to ride in a 240Z powered by a turbo L28 motor around Road Atlanta. That one had been tuned at DIYAutoTune and made over 300 horsepower to the wheels. Thing was quite a rocket! |

These are very light cars. I think the motor is more like a 170 slant six. Just basic fundamental 1960s technology, not all that different from the slant six. The light weight makes them quick. Some Datsun L series fours got crossflow heads in the '80s but the L series sixes were still the performance models thru '86. Nothing fancy for sure. Smaller valves than the Mopar six. The SSS heads might be worth a look for a theoretical custom slant six head(in my dreams), has heart shaped chambers (closed chamber), slightly larger ports, nothing fancy. SSS work well given their simplicity. The OHC helps with some high RPM, but pushrods would also work with this simple head design. Inline sixes are good. Really simple and so smooth. Sub 2,400 lbs weight makes these quick. |
