Rotary'14,
You had a rotary engine in a 914 quite a long time ago... who is the first person that ever tried it, was it you? You already have a Megasquirt EMS? I want to decide which EMS to use for my car. I need some information on the topic. I also want to find out if a intercooled supercharger setup would work with the N/A, I know there is a lot of controversy about detination with the higher compression... but the N/A compression ratio 9.4:1 doesn't seem that different than the later turbo 9.0:1 . I might just try it if I can afford to buy a P1SC procharger. Everybody says just buy a turbo motor if you want to have a boost... but I am thinking that the N/A manifolds and porting might be well suited to supercharging. I plan to have my oil cooler in the drivers side wheel well, and possibly an intercooler on the passerger side. I don't want to change 914 GT look too much by making huge air inlet ducts right infront of the rear wheel flares... so plan to make them discreet, some how. Maybe with a grill, or just louvering. Any body have experience with this? Rocks and debris must kick up in there so what? make a wire mesh guard? I was planning on tilting my radiator forwards like the rx-7 and then exit the hot air right out the hood. Anybody buy complete 7" and 9" fenders and quarter panels? I did. I forgot if I bought them from AIR or where else. I'm not impressed with the finish around the edges... looks like they were cut by hand with a hacksaw. They are pretty light weight too, I think they would need exessive braceing. I plan to make my own copies of them. Maybe a one peice front and rear. That adds at least 6 months to my project, more likely a year. I don't think the shift linkage length will be an issue for my car because my center tunnel an fire wall are all reconstructed. I am actually placing the shifter in a new location, it is a little higher up. I can still play with the left and right and forwards and backwards possition. I hope I haven't compermised the shifting, but things can allways be cut and welded later. Shoots...then. I have the day off so I hope to do some work on the car. GOod luck everybody |

You don’t have to worry about turbo charging or supercharging a non-turbo rotary engine. It works just about the same. Just remember that the rotaries like lots of fuel. You will however be limited in the total amount of boost that you can safely run. The big advantage to using a turbo motor is bigger injectors, harden stationary gears, slightly lower compression rotors and bigger throttle bodies and intake. If your intend on keeping the stock configuration. FYI there is available very low compression rotor in the range of 7 to 1 and 8 to 1. I had a set of the 7 to 1 ratios. What a kick in the pants when the boost comes on. Total madness. No traction in any gear. Then there are the issues regarding the 3mm ceramic apex seals and the 3 and 4 rotor. Don’t get me started; I can go on and on and on. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

Hi lybones (Tom)
I too was impressed by your yellow 914. Could you please post some closer pic of the front end of your yellow 914, particularly the opening for the radiator. I like how you did not have to cut into your chrome bumper, very clean look. Also if you be so kind, some photos of your raditor in your front trunk. Thanks in Advance Ted Fellow rotary 914 bro |

I'll have to find his e-mail address again, but there is a fellow 914/rotary motor guy down near New Orleans I believe...he is running a Haltec, I meet him on the yahoo groups for Haltec. I know there are a lot of Haltecs being run on rotaries.... |

I am running Haltech on my rotary, what would you like to know? Easy to set up and tune on the fly. Makes gobs of power. Very user friendly.

Turbo914V8,
Which model Haltech? What stock sensors did you use and what did you replace? |

If you are looking to go with a Haltech on a rotary the best choice would be the E6X or E6K. The E6K is the earlier model and is no longer sold new (the E6X replaced it) but it can be found used. It's reliable and proven to work well with the 2 rotor engine. Plus there is a lot of support for it on a rotary. (maps,etc.)
I purchased an E11 for my 3 rotor as I needed the ability to run the split timing on the 3 rotor (the E6 series only runs the split timing on a 2 rotor). The E11 will also run the 2 rotor but would be overkill. These guys in Canada have good pricing on the Haltech units: http://www.magnusmotorsports.com/engine_management.htm I believe the quoted prices are in Canadian pesos. |

Ted, My car is currently under the knife again. so I will have to take new pics. I actually swapped out that front chrome bumber with a fiberglass one. I originally cut a large horizontal slit on the front valance to avoid the hole on the chrome bumper. But it just was not adequate enough to cool the car. I know they make nice front spoilers that has a scooped opening now. My v8 swap is almost complete. Here's a more current pic of the car. Attached thumbnail(s)

The ECU's from PerfectPower are inexpensive and configured to run on rotaries as well (2-rotor only, I believe). My MIC3 ECU (PerfectPower) has a rotary mode. You just pick it as an option in the software and go. This discussion is very interesting. I am once again distracted in my quest for a replacement powerplant. Scooby turbo? Rotary turbo? Six? Six turbo? 928v8? sigh... -Ben M. |

I used a Microtech ltx-8 standalone with hand unit for in car tuning. Some of the worlds fastest uses Microtech. Comes preconfigured for your engine type. I just wired it up and started the motor on first attempt. Required tuning was actually quite minimal! These units are big in Australia's rotory scene and is making a name for itself in the states now.
My two cents would Microtech or Haltech. Both are awesome. http://www.microtechusa.com/prodinfo.html |

Hi
Did you guys notice the "oddball" attraction to a 914... and the same attraction to a "oddball" motor wankle...
I said the same thing, almost... This is a proven swap for the 914. We are better now equipped to handle the lacking (drivability) details of 20 years back... I am surprised this is not a V8 alturnative(sp). Rock on Later Joe (IMG:http://www.914world.com/bbs2/html/emoticons/beerchug.gif) |

One of the downsides to the Microtech is that the unit has to be configured in Australia. If you buy one you have to tell them what motor it is for and what you are running with it. If at a later date you decide to change engines or want the unit to control something else (like a BAC valve for example) you have to send the unit back to them. It seems ludicrious to me that you would have to keep sending the unit back to get it configured when the whole point of buying a stand alone is to get away from having a pre-configured system (ie: chips....make some changes need new chips burned.) Also the Microtech does not have the same resolution as the Haltech so the control of fuel, etc is not as precise. A friend of mine bought a Microtech based on the reported ease of use and quickly changed to a Haltech. Most of the guys running Microtech in Australia do so on their drag race cars where all you need to do is dump the fuel in for a short run. Having a stable idle or good transition from on/off throttle is not as important and you can get away with less. I'm not saying the Microtech won't work. I'm just saying that the Microtech has several built in faults that the Haltech does not have and it costs the same. As for the Perfect Power units - I have an SMT-6 for my 944 Turbo but in the 7 years that I have been involved with guys in the rotary community I do not know of anyone who has used the Perfect Power unit. I'm assuming there must be a reason for this. It may work fine but I don't expect there to be much support for you if you need assistance with tuning and installation. Just my $0.02
lybones: Really nice cars you have and the quality of your installs looks top rate. I will aspire to get my install in as neat and clean as you did. Good work Ollie! |

Sorry, but I have to back Soloracer on this one. I totally agree with what he has said and will attempt not to repeat it. Both the Haltech and Electromotive seem to be the systems to use imo. As I stated earlier, I use the Haltech on in the 911 with the wankel and Electromotive in the 914 with the V8. Both are turbo charged. For the money and ease of in car tuning, I don’t think that you easily beat the price. The key thing here is that there is a lot of support for the Haltech and the wankel, as Soloracer stated you can download free tuning maps for the rotary and be up and running in less than an hour. I don’t know of any other aftermarket FI system that can top that.
Regards, Turbo Paul. |

Joe, I have been involved with the transplanting of the rotary in to all kinds of crazy rides since it’s beginning. After dusting of the competition most cannot believe that it’s a rotary motor. I think the general public or racing community is just starting to relies the power potential of the wankel, with it showing up in some of the drag racing events and kicking a$$. And that’s only with the 2 rotor. We have not even begun with the 3 rotor yet. Soloracer will be the first there, if he gets off his but and finisher his machine (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) I have plans to build a 4 rotor and open a can of whip ass on everybody. Just at the moment I have my hands full for the next few years. I figure the 2 and 3 rotor is just catching on now after all these years, so I have plenty of time to play with the 4 rotor.

Turbo Paul,
Which rear bumper is that on your car? Where did you get it? |

Well, I got off my booty and I managed to pop my engine up into the body. Man I think the engine fits very well. The main reason I am using the MegaSquirt is because I am cheap and this system did what I needed. I plan on using it fuel only and run a distributor. Do you guys think that mounting a fuel control ECU in the rear trunk, would expose the ECU to too much heat? Here are some pics,,,, Attached image(s)

Hmmm,, scott thatcher's subie makes 350 HP with the radiator in the back,, I wonder if his cooling set up would work with my engine, my engine is only going to put out 220. Then here is a conversion that doesn't put holes in any trunks!

This is the gap between the intake manifold and the rear trunk,, plenty of clearance!
