You need and MSD coil like this?
http://sfbay.craigslist.org/sby/pts/2491630329.html And the bigger box one like this? http://sfbay.craigslist.org/eby/pts/2490164909.html Also try e-mail this guy to see if he has a working factory unit:http://sfbay.craigslist.org/eby/pts/2496889392.html Matt QUOTE(kg6dxn @ Jul 17 2011, 06:35 PM)  Worked my ass off today. Almost got it started. I first found a bad fuel pump relay. Had one, easy fix. Then I found the Mazda ignition module bad (IMG:style_emoticons/default/sad.gif) I need a work around. The factory Mazda part is $800. I'm looking for some MSD 6A's or 6AL's. I need 4 of them with coils. Everyone look in your parts bins and give up your extra MSD's. PM me if you have one you want to get rid of. I don't really want to buy new ones $$$. See what you have and hook a brother up! |

QUOTE(kg6dxn @ Jul 16 2011, 09:46 AM) I talked to the seller of this 914 book. He has a long time relationship with the author. Still alive, 83 and living in England. He buys NOS books directly from the source. Pretty cool. He has many more to sell. My book came today - lightning-fast service! From Santa Ana, no less (where another vendor shipped something last MONDAY and won't arrive until _tomorrow_...) Boys and girls, in case you don't know what this book is, lemme fill you in: It is a big-print (i.e. READABLE) version of the long-out-of-print 'Technical Specifications' (i.e. - "LITTLE SPEC BOOK") of _both_ the 914/4 and the engine section from the relevant 911 Spec Book. Yeah - it says '914/4' om the cover. The /6 stuff IS IN THERE! It is therefore an INCREDIBLE BARGAIN and means I can mostly retire my actual Little Spec Book originals to a safer location. ALL the weights, measurements, torques. Even disassembly and reassembly instructions which the Spec Books never had. Exploded parts diagrams. Separate wiring diagram which is unfortunately in B&W and 914/4 only (year unspecified...) but still a winner inclusion. Won't replace the Factory Repair manual, nor even probably the Haynes, but for a single concise reference for those weights, dimensions, and torque numbers - it's a home run. BUY ONE. (No affiliation, just a happy customer.) |

I found a cheaper solution. Haltech makes an Ignitor module. I'm looking at the quad channel ignitor. This will allow me to keep the wasted spark on the leading plugs but also gives me the option to go with 4 direct fire coils. The two lagging coils are already direct fire. The leading coil is a basic dual post type. The Haltech module is directly compatible with the ECU and I won't have to loose the real estate to mount 3 or 4 MSD boxes.

I got it running today. It doesn't run great yet but it runs. I hit up the junk yard and scrapped out parts from an RX7. Coils and ignitors. Now I have tuning and clean up to do. the interior is a mess from 9 months of work. The trunk is full of tools, documents and parts. I did notice my #1 trailing coil is not firing. Inductive timing light will not work on that wire. Works on all the others. If I can't get the trailing coil to fire by noon, I will go back and exchange it at the scrap yard. The temp at idle stabilized just under 110F. As the rpm goes up the temp comes down. Found a minor oil leak at a loose AN fitting. fixed it. all fluids stay in the engine now. It's very exciting seeing this POS run.
Big thanks to my wife for putting up with me for over 16 years! (IMG:style_emoticons/default/wub.gif) Here is the video of the initial run. A neighbor came over and asked if it was a 4 or a 6... (IMG:style_emoticons/default/happy11.gif) https://www.youtube.com/watch?v=NG5J0FQyxno |

I did some tuning and some driving today. I figured out how to use the auto tune mode with the wideband sensor. It's a 2 person job or a one person on a dyno job. This thing is waaay faster than my V8. It revs up real quick. It does like first gear but I'm hoping to be able to take off from second when I get it tuned better. I'm just not used to shifting from 1st to 2nd. I never used it with my v8. I missed almost every shift. It does not like going from 1st to 4th... BOOOOOGGGGG! The clutch is perfectly set. The shifting is tight, but the 1-2 thing needs practice.
The only bummer is that the oil injector pump does not work with the controller I have. The problem is the TPS compatability. I need to rig up a second TPS or find a dual TPS setup. My contingency plan is to swap the front cover and use a mechanical oil injector pump (I have all the parts). Then I can use a cable linked to the throttle to actuate the pump lever. Early RX7's used this style pump with a rod to move it open/close. The temp is stable while driving between 180-190F. While parked in the driveway it gets up to 208F. At some point I will add a inline booster pump to help with flow. The stock water pump just can't push like I want at idle. There is a good one I can mount on the lower rad line up front. It has a thermostat to keep the water flowing after shutdown. When I first started the engine, the engine was at 200F and the radiator was at 75F. I revved it up and the coolant started to flow. I'm running pure water with 4 quarts of Water Wetter. I have no idea how to use my boost controller and the instructions are confusing. The Innovate turbo timer works perfect. I just don't know how to change the time. It's set to keep the engine running for 30 seconds after shut off. The pyrometer has the exhaust temp around 1000F tooling around the hood. I'm sure it will go up as I start driving it harder and harder... And when I get it tuned better. I set it up rich so I tune it lean. That keeps the tamps down and saves the engine. Finally, the rotary compression cannot be used as a parking brake by leaving it in gear. I might have to source a real parking brake now. Anyone have any 930 Turbo parking brake stuff? I'm going to have my wife help me tune while driving... unless there are any voulenteers here. I am happpy with this conversion. It is going to be a very fast 914. Much thanks to all the PO's for setting up as a race car. I think the roll cage is very appropriate for this setup. The BIG. brake are going to help too... Here's a pic of the water pump I'm planning to add. Pricey at $400... (IMG:style_emoticons/default/sad.gif)  |

Wow it does sound great. My wife had 2 RX-7's when I met her so I know how fun the rotary is to drive. Very cool.

Wish I was closer... I'd love to help you tune that!
Im not sure that I would be using 1st gear all that much... I would be seriously scared of killing that trani... |

Wow, this is an awesome build, i keep going back and forth between a rotary and a subaru. If I lived closer id be all over helping you tune. Ever thought of going E85? The you shouldn't need two people for the autotune. Just set the desired AFR in the desired cells and drive. You probably wont hit every cell but after a while you'll be able to fill those in.
I think the gt35R is way overkill for only 15lbs of boost, but hey its your car. I think you could go with a smaller setup and get way more response and faster spool. QUOTE I have no idea how to use my boost controller and the instructions are confusing. The Innovate turbo timer works perfect. I just don't know how to change the time. It's set to keep the engine running for 30 seconds after shut off. Are you using an external wastegate? Is it a manual boost controller? good instructions for hooking up a manual boost controller PM me if you want the essay version of how they work Boost controller diagram Im not familiar with the innovate turbo timer but 30 sec is fine for any turbo. If you track it you should drive around the pits to let everything cool off a bit anyway. Dang I wish I was closer. How much was the motor if you mind me asking? |

Have a look at the electric water pumps, direct replacement on series 4 onwards, weren't that expensive from memory, should be able to control it from the haltech, we have been running one on a 20b twin turbo drag car doing low 8s with no issues, I am looking to use one.
Car sounds great can't wait for more videos |

If you track it you should drive around the pits to let everything cool off a bit anyway. Dang I wish I was closer. How much was the motor if you mind me asking? The turbo spools super fast. Full boost by 4K rpm. I have a T4 manifold with a ported contoured T3 adapter. It is a ball bearing turbo, oil and water cooled. I went with this turbo for room to expand my hp. The goal is still 300-350hp with room to grow when I pull it appart to port it. Remember this little engine pulls in as much air as a 2.6L engine. That's how they make all the power from a little package. I am running an external HKS WG with an 11psi spring. I have a 6-8psi spring to swap in if needed. I never owned a Subie but I have had several rotaries. I love the rotary. quick rev and high hp with a 8k redline (or higher). I do feel the 901 is a limiting factor on how this car will be driven. I need to save my nickles for a sequencial shift tranny. It would be perfect for this setup. The boost controller is electronic. I played with it last night. I think I got it programmed to 16psi. I need to set my ECU boost cut higher. I agree the quick tune will work with one person, but I keep finding myself looking at my laptop while driving. It will be easier with someone else driving while I tune. |

Mike lets be honest here, 300-350hp is a ridiculously low goal with that big of a turbo..
IMHO with 15lbs of boost you probably will be in the 400hp range.. I know guys that run that turbo on the 1.8T audi's are making 500+hp but they have to push 25psi. How predictable is that turbo so far? I know tuning has a lot to do with that, Im just curious how its going. |

I know tuning has a lot to do with that, Im just curious how its going. OK, you got me. I wanted to state a conservitive HP number and not to claim something ridiculas. I will not be dissapointed with 400hp since the torque comes on slowly. tuning is going good so far. I only have about 4-6 hours into it thus far. I spent the first day tuning just to get it to hold an idle. Then I made the video. I stopped at 4pm last night to keep from getting burnt out on it. Just getting it running was a heck of a goal. it spools up to 20psi fast! then my ECU is cutting back fuel. I think I have the boost controller dialed in to 16psi now. We will see in the next few days. I might not get to it tonight due to my work schedule, but I will get to it as soon as I can. The turbo was chosen with room to grow. |

I think its a great "room to grow" Turbo If you love the way it spools then its perfect for you.. 4k of usable RPM range is GREAT!
Also.. You know thats a 600hp turbo... (IMG:style_emoticons/default/smile.gif) Just curious about traction.. Are you having any traction problems when the boost kicks in? Im SURE first gear you do, but what about second? |
