I am assuming that your car is a mid engine (other wise the linkages are easy to work with)? Also I have to assume that you are referring to the B series engines since the the H and K are cable driven. If so you need to create a bell crank setup like in the picture below. Attachment: shifterB18-1.jpg This inst too hard to do. The right cable will pull the shaft in and out and the left will rotate the shaft. You use the turn buckle to adjust. The above kit is by Sunspeed which was made to put the B18 engine into the Lotus and they have discontinued it but have some parts so they can still make the kit if you want for $850. I think I will make my own and if works I will tell you how to do it ; ) |

In a nutshell, you take the stock shifter and turn it around to point at the engine behind you, and run the cables to the same points. The detail is that you must fab your own cable mounts at the transaxle because the cables now run forward. Really, it's that simple. Check out my mid-engine Honda projects at http://www.midlana.com and http://www.kimini.com. |

Yeah the H and K are much easier to work with and the K series has a lower center of gravity and it rotates in the right direction! Also buy Kamini book! It is well worth the price more like a steal ; ) |

How would i use the other series (H and K) engines? |

I generally use 2 sets of cables with a pair of simple quadrants halfway. The quadrants are completely shape'able allowing me to change the leverage ratio (shortening or lengthening the shifter throw distance) and or reverse the operation which allows a range of different manufacturers gear change assemblies and allowing more gentle straighter runs for the cables. For the quadrant pivots I just use a nut welded to the quadrant and a bolt welded to the chassis (good quality fine thread) - make sure you have room to wind the quadrant on as it needs to swing 360 degrees as you wind it on. This example is 1:1 ratio and you can see the 3 basic output directions to the transmission but that is only limited by your imagination. Last one I did had a short forward and back shifter throw but a wider sideways gate throw so the 2 quadrants were not the same. |

On the non-cable shifted B and D series engine/trans there is no need to build a complicated linkage to cable conversion as shown above by mjalaly. It's actually far easier to implement than the cable shifted transmissions. All that is needed is to make the OE selector rod shaped like a J at the transmission end, instead of straight, allowing control from in front of the engine (in a mid-rear engine application) and retaining the amazing shift feel these have straight from Honda. Here is a picture of an S80 style transmission (from Integra GSR) mounted in a mid engine configuration with the simple shift linkage made from the OEM part. |

Snailed, Is that a u-joint connecting the rod to the transmission in the rear? |

Yes. That's because the shaft not only rotates, it's also doing a push-pull thing. Think "rows" and "columns" for gear selection. |

Correct I have just never seen a u-joint like that This is the closest i could find http://www.nfauto.co.uk/images/oct06/un ... nt_new.jpg Some how from the way it looks, it seems to be turning 90° |

| Post subject: | Re: Shifter Cables? |
It is turned 90* but that is not necessary if you made the selector shaft with a sharp bend on the end. I was mistaken on it being the OE one though. The honda one is larger and constructed differently (at least the ones I have had). The style of joint really doesn't matter though as long as it can be configured to have a little bit of freedom in each direction. I was just trying to point out how simply it could be done, use whatever joint is strong enough and fits where you need it. |

Does any one know if the shift stabilizer needs to retained in the above configuration? |

Ok so i am having shifting issues. Pretty much it makes me not want to drive the car so now its on my priority list. I will try to post better pics tonight for suggestions. Pretty much the way the chassis is designed, there isnt enough swing in the shifter to make it easy to get into first and if i do add it in, i either hit the lower chassis tube or the oil pan. Maybe switch to cable shift? |
