What is the hardest car to work on

[badassgremlin]

the hell kinda question is that?

Rotories if you dont know anything about them. But in reality they are simpler than a piston engine.

Cant they go up to like 20,000 RPM?

And what kind of car's have them, I know they used to drag race them, and I know their in rx7's

20,000 no, BUT! they can rev well into the 10,000's and the cars that have them are all mazda rx7's the new rx8 as for drag racing i dunno but they were frequently used in lemans for there reliability (though they used more oil than a 2stroke lol)
GM also had a rotary program in the 70's i belive but they scrapped it

yes chevy was talking to wankel in the 70's about a rotary powered Corvette, but decided the engine used to much fuel, so mazda took wankel up on the offer.

Actually, a number of companies were working on Wankel engines in the 1960s and early 1970s. Only NSU, Citroen and Mazda actually put them in cars (Suzuki put them in motorcycles), and Mazda's rotary cars were in production well before GM gave up on rotaries. Mercedes-Benz was another one of those companies toying with these engines.

I have heard that AMC had planned to use a wankel engine in the Pacer, but changed their mind to save money. Am I right?

As for hard to work on engines... Subaru's DOHC engines are a pain in the ass to change sparkplugs on, but that's really the only reason they're a pain in the ass. Toyota Corolla's the front wheel drive versions (excluding the corolla-tercel, which isn't really a corolla) Where the gas filter is an absolute pain in the ass to remove and replace - ugh!
But I haven't had more experience with cars other than Subaru and Yugo so I can't say too much.

yeah i would imagine horizontlly oposed engines would be hard to work on

Partially. AMC did design the Pacer to use a rotary engine. In the middle of development, GM (the planned supplier of Wankel engines to AMC) dropped the rotary engine project. AMC, now with no engine for their car, needed to redesign the Pacer to accept the AMC six-cylinder. It wasn't AMC's mind that changed.

now wouldent that be a bitch?

from what i've been around, anything that has a Lucas electrical system.

The Wankel engine was also considered for use in aircraft at one point. In a 2-rotor rotary engine, there are only 3 moving parts...the two rotors and the crank. Pretty damned amazing. Check out the huge section on www.howstuffworks.com about the rotory engine or hit up lycos. Friggin ingenious.

rotaries are the prefered engine in smaller planes for its light wieght nature.

10k rpm is very easy to attain.

the mazda rotary was used in only 1 le mans race that was 91 where it was immediatly banned from ever racing again when they swept 1st 2nd and 3rd place.

The rotary actually killed NSU.....they were too unreliable at the time, and the RO80, which used them, were relatively popular. New engines every 20000 miles wasnt uncommon, under warranty of course. And they went bankrupt.
