Here are the "way to tall gears"
US WRX (stock tire 205/55-16) Tire circumference is calculated Gear Ratio Final drive Total ratio Tire Circ. Rev./Mile 1st 3.454 3.9 13.4706 78.15639 10920.38 2nd 1.947 3.9 7.5933 78.15639 6155.753 3rd 1.366 3.9 5.3274 78.15639 4318.828 4th 0.972 3.9 3.7908 78.15639 3073.134 5th 0.738 3.9 2.8782 78.15639 2333.306 I don't have the 901 ratios handy but I remember they were pretty close if you have the 4.11 or 4.44 final drive in the Suby. I think many of the Legacy FWD had taller gears (3.7 final drive) The NA small engine (like 1.8l) transmissions had the "better" gear ratios (closer and lower final drive) |

Food for thought - off topic but you do need something to bolt the transmission to.

Slow - my new baby is really slowing me down as far as the swap project is concerned. I should have some progress this weekend thanks to James. Plan on at least $270 for a set, I'm probably not going to sell the flanges separatly (meaning you will need to buy the full kit) to people except to those that have been in from the start. Don't worry guys (you know who you are) you will be able to do whatever. The 3 people I'm talking about have been in from the start. They have also been helpful with the project. |

You can really see just how much angle the Suby engine is mounted at looking at this picture. Looks like at least 10 degrees. |

So who's going to put together the CSOB plug 'n play kit?
Flange/CV/Axel/Hubs - Porcharu Wiring Harnes - ? Engine Mount Bar - Scott? Mid Mount Rad housing/scoops - Scott? Cable shifter - Wbergtho Or maybe a set of the sorted designs for the fabricator pros? Great job on all the development work guys.... (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif) |

Best bet is buy all the parts from the same person or make damn sure one part is compatible with the other parts.... I believe Steve had planned on making an engine mount bar as well as a radiator mount. My money is on Steve since we know he's making progress and we have not heard from Scott in a quite a while with respect to a "kit" from him. |

There is a big difference between what Scott (Tony and Renegade) has done and what Steve is doing.
Scott has an EJ25 mated to a 914 tranny. See Tony's thread for dims on his engine mount as he is also using a 914 tranny and an EJ motor. Both are using $1000 in KEP adaptor parts but can use a stock 914 axle assys, shift linkage and speedo cable. Both have one off custom oil pan modifications as well. Great job guys !!!! Steve on the other is making mounts and all for a Subaru EJ motor and for both the Subaru 5spd AWD and Subaru 5spd FWD trannys meaning no need for expense of KEP adaptor parts. |

That would be me. I don't know what your idea of "cheap" is but I'm not going to get rich selling these things. I hope I can break even. What I have in the works is a "hard parts" kit 1. Engine and transmission mounts - these bolt to the stock locations so no drilling/welding or cutting will need to be done to the car. 2. Radiator mount - engine compartment mounted radiator. I want to make this part of the engine cradle so everything is one "pod". 3. Custom adaptor flanges to allow the use of axles made from stock parts to fit the Subaru transmission. 4. Shift linkage. I have a design in my head for a cable setup, but a rod system may also work. I have no plans on doing a wiring harness. Other people already do this (smallcar.com) and I am using an aftermarket EFI system on my car. I am not going to sell plans because somewill go into bussiness selling my ideas. I am showing everything I do in my blog that you can copy if you want. I will price the kit so it would be silly to do it yourself unless you have all of the tools and like to fab stuff. |

Porsharu-
Very cool, can't wait to see the final package. How will your aftermarket EFI interface with the stock harness? Which EFI are you using? |

It will interface with the stock harness by never touching it. The stock subaru engine harness is gone. I'm using and SDS system. |

Some progress today! I called work and told them I'm working from home (forgot to mention I would be working on my car!!)
James sent me a pair of Subaru flanges so I could mock up the adaptor flanges that we need. I promptly chopped one of them up and tacked it onto a 100MM VW output flange. Attached thumbnail(s)

That is a good example of just how much Subaru tilts the engine - the plenums are level in the car. |

Porcharu, I have been following this thread, but not contributed as I am no where near buying of engine/g'box stage but once there will provide any help as necessary. I am very familiar with subaru's, having owned a number of WRX's stock & modified including an STI back in Australia. I will contribute here as much as possible... Please make sure you give yourself the opportunity, at minimum to break even. The work you have already done will help many people, myself included, and you should at least get some additional benefit out of it. Keep on working at it, If I end up with the subaru engine/trans combination your 'kit' is the top of my list. My C$0.02 about US$0.01. |
