Hi!: as you all know, the AMC Pacer was designed around the Wankel engine that GM never put into production; it seems they had some trouble solving the exhaust emissions issue. Anybody knows if the Mazda 13B RE, or other will fit the Pacer's Chrysler 3 speed automatic gearbox (Torque command-Torqueflite 904)?. Is there any previous experience on this?. Somebody can give a tip? Thank you in advance, best regards, salut + JGA
AMC 258 6L 2V carburettor gave 95 hp at 4'300 rpm,and a torque of 250 Nm at 1'800 rpm, slower than Mazda. (The fuel use of my AMC Pacer ranges between 12 and 18/lit/100 km,(12-20 mpg?) depending on trafic and driving style) |

Probably the 13B 6 port. The hesitation is likely due to a grounding issue. http://www.aaroncake.net/rx-7/grounding.htm |

It seems it was first registered in March, 1988, thank you very much for your continued help. |

What year is the RX-7? They were made from '78 until 2004 and with each generation, the engine setup changed totally. |

Hi !: I've found in Malaga, Spain an Rx 7 with 65 k km, the owner wants some 900 U$, but he says that the engine runs well but if you want a fast raising of rpm, around 5000 rpm the engine starts hesitating and stops accelerating, while if you race it more slowly, it goes well beyond 5000 rpm. Any guess about the kind of fault, and if it would be difficult and costly fixing it ?. Regards, salut + |

Well good, because the world won't end next year.  Those people who believe it will, we call crazy.
Fuel economy is not going to be the strong point of any rotary though. With a well tuned ECU, about 30 highway MPG is possible but I'm guessing you'll be using all stock electronics, which are rather dated and crude. The stock stuff tends to run pretty rich most of the time.

I now own an automatic gearbox for a Mazda Rx 7 engine, and keep on looking for a decent engine in the shops. As the AMC Pacer never had an engine giving more than 150 HP, any non turbo engine of the last generation will be good, fuel economy being an important point, my current 258 engine uses between 9 and 18 lit / 100 km. The seller cancelled the sale of the core engine mentioned above. I won't make you waste your time in my personal case anymore. Thank you for your patience and cooperation, Merry Xmas and Happy year 2012 ( I don't believe the world will end next year ) |

I would suggest getting rid of the thermal reactor and going with a standard header, unless you have to retain it for emissions purposes. You'll save a lot of space, and then it will be easy to make the exhaust cross over underneath the transmission or driveshaft to the stock exhaust tunnel on the opposite side. Make sure to include at least two quality resonators and a good stainless muffler to keep the noise down. |

Happy year 2011 for all !. I've realized that the Pacer 6L engine has the exhaust manifold located at the driver's side, while the Mazda thermal reactor is at the passenger's side. Any tip ? Salut + |

I don't have any reference for the engine numbers, and I don't think they are very meaningful outside of Mazda.
Dizzy = slang for "distributor".
If you don't have to pass emissions testing, toss the thermal reactor in the garbage and get a nice header on there. Good for about 20 HP. The thermal reactor, while quite cool and unique, reall cuts down power. Exhaust flow is one of the most important things to consider when making power with the rotary.
It's doubtful that it will bolt up to a Chrysler transmission.
Why not go manual? The 5 speed from any other Mazda rotary will bolt up...for the most part. You just need to match the flywheel/starter/clutch to the transmission used. |

My engine has the number 18100. Do you know the reference for the electronic control box that fits ?. Does it accept Chrysler torqueflite automatic transmission ? Should I buy a Mazda automatic gearbox ? Thanks a lot, salud + |

Thanks a lot. It's NA and has a thermal reactor exhaust. I've already bought an ECU, delivery pending. What is a dizzy ?. Salut + |

86-92 came in both NA and turbo form, so you have two basic and obvious choices.
If the engine is 86-88, then you need a matching harness, ECU, air flow meter, solenoid resistor (if applicable), variable resistor from that range of years (called "S4").
If it is S5 (89-92) then you need the same stuff minus the variable resistor (not used).
If it has a distributer, then there are a few more choices. Some models for export didn't get coil packs but instead got a dizzy and thermal reactor exhaust. |

It says 13B INJECTION
MAZDA
I'll try to attach a picture, the seller indicates is years 86-92.
Thank you, salut + |

Is the engine turbo or NA?
If NA, does the intake manifold say "RE-EGI" on it? Or "13B Injection....Mazda"?
If turbo, single or twin turbo?
Actually, it would be quite easy to identify if you post a picture. |

I've bought here a 13B Injection , four spark plugs engine from an RX7, but as I don't know the exact year, there are doubts on the kind of electronic injection and ignition control box that fits. Somebody giving me advise ? Thanks, salud + |
