thats got to be some kind of record. 6 rotary cars owned and no blown motors!

 

I said I drove them in the winter. I didn’t say it was easy (or fun).
I have started and driven all my RX-7s (except for the 1993) at 30 below zero. They had 5W-30 oil and had an electric block (rotor housing) heater. The RX-3 would start at 30 below without using the heater. It had a cold weather starting assist (stock on Canadian cars). It would inject regular antifreeze into the combustion chambers. That kept moisture from freezing the apex seals. You had to change the oil more often if you used it much. If the R-100’s electric heater was plugged in, it was OK. Without the heater, it was unusable below 0 F. The engine would start, run for about 2 seconds, and quit. The apex seals would freeze to the rotor housings and the engine was seized. It would then start and run OK if the electric heater was plugged in for a few hours or if it got warmer outside. RX-7s are really bad in the snow!

 

Cool information!!! So I cant take my future rx7 to the snow? or wankel will freeze over....

 

not true at all, gtr's are great to drive and the rb26 is a beast of an engine. of course, i dont recommend that you buy a gtr if you have no experience with performance cars as they are very unforgiving, and are much quicker then 7's, although the fd is much more agile.....

 

Not really, just because they hadn't turbo'd the renesis doesn't mean that Mazda concluded anything. For one the renesis apex seal is designed like a skeleton, and, the way that appears to me is it is much weaker than the rx-7 apex seals, so it would be more susceptible to breakage under more pressure, thats probably why they didn't turbo it, + they are making decent horsepower na. Look around you how many new sports cars are coming out turbo'd not very many? The market right now seems to be in favor of high compression turboless engines. Lets face it turbo anything is gonna cost you more, and be less reliable than it's turboless form.

On top of that I know a few turbo FC's that are at 150,000 on original engines, no rebuilds, and still hitting low 14's in stock form. That's one thing about the rotary they still retain their power even 150,000 miles down the road.

 

Is an Rx7 expensive to own? Its all relative. I'm sure there's a braniac on here (cough!jimlab) who has an algorhythym to figure the probability of engine breakdown, lugnuts fallin of etc... But if you actually READ this forum and the related sites an intelligent person can judge the risk for himself. (no dis at all jimlab IMO you own this forum)
