Come Steve, I don't know if you are the one to talk about better engines, based on toyota's recent record. ![]() Awesome shop. I love the Cosmo. |

120k miles, 3 engines. stock except for cooling upgrades. If they were great engines more people would use them. Shitty gas mileage for what it is, apex seals, loves oil. That's just me others love them, I don't. Still the pictures are really cool Edited 2 time(s). Last edit at 07/16/2013 05:02PM by czwalga. |

I take it as kind of a compliment. Hey, great car, and since we're American hot-rodders we're going to throw a different engine in it. The FD did have two major flaws with it that prevented it from being a reliable car... the primary turbo, and the secondary turbo.
While renting dyno time at another shop, we had a look-see at some of their customers' and employees' cars. They had a very sano '68 Tempest with a LS2/4L60E swap. They used an actual GTO engine and painted the engine and the raised sections of the engine cover Pontiac blue. Looked almost like someone time-warped the drivetrain to the late 60s and put it in. And one of the employees was almost done with his truck 5.3 + giant turbo (HX52? giant Diesel thing) swap in a '90ish Mustang, because that IS the cheapest way to stupid power in 2013. The biggest problem becomes traction, the second biggest problem is getting a transmission to live in between the two. The rotary's biggest advantage is that they're cheap to upgrade. How many engines can live at 9500rpm with nothing more exotic than a little machining on stock internal hardware? How many engines can make power up there with nothing more than some more judicious metal removal from other areas? Gotta love it.

Except rotaries are some of the most reliable racing engines out there. I've known guys that went well over 10 years on the same engine in their race and rally cars. I never did that with any piston engine. The engine in Dave Hintz's old RX7 rally car which I built in 1999 (Dave had that engine rebuilt the year prior) has been going strong for 15 years and three different owners and that's a turbo with some mods. Scott Koch is running the car now.
If you went through 3 engines in 120k miles in a street car then you were doing something wrong. |

Frequent the rx7 forums, its more the norm than the exception. The NA engines were better, but anything with a turbo not so much. The 3rd one was still working when i sold it. Not really trying to get in an argument over it, but really if they are that great you'd think they'd be used more no? Really I was just trying to make a joke, rotary fanatics usually get all up in arms when you say anything negative about it. ![]() Edited 3 time(s). Last edit at 07/17/2013 06:51AM by czwalga. |

Someone I know put it best when he said rotaries are excellent race engines but crappy street engines. My bridge port makes approximately 230hp at the crank with a streetably quiet exhaust (it is, in fact, the car that I drive about 800mi/week as a daily driver) and decent road manners (and it gets 25mpg!) but I'll admit that it's far from what most people would consider to be a good street engine. Makes lots of neat noises though.
That's about normal for an FD. MTBF for an engine is about 60k. Between the cramped engine bay and the restrictive twin-turbo setup and the crappy intake manifold so that they need to make boost to do anything at all, the engines are one big fat heat problem.
