Guest Anonymous Posted October 1, 2000 Share Posted October 1, 2000 What did you have to do to set up your Z for the rotary swap? What did it cost, and how difficult was it? Like I said, I am thinking about it myself. Also, does anybody know anything more about that Supra swap I mentioned a while back? Thank you-Thank you!

Guest Anonymous Posted October 16, 2000 Share Posted October 16, 2000 That badboy will probably cost even more than a Mk IV Supra motor. I have never personally seen one, though. Quote Link to comment Share on other sites More sharing options...

The v. odd one has been stuffed into a 3rd gen Rx7. The 2 rotor Rx7 model would be nice in a z if you could avoid a lot of their maintenance/breakdown troubles others have experienced. 2 rotor being a fair bit shorter than a 3 rotor which takes a lot of mods on a 3rd gen Rx7 to stuff in. 2 new motors for this one http://www.slip.net/~ysong/redshift.html if anyone has a good URL on the 3 rotors I'd enjoy reading up on them (even a good 2 rotor writeup would be enjoyed, do they get mpg to match their high hp/litre #'s? (196hp/litre stock) Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted October 19, 2000 Share Posted October 19, 2000 20B engine Dimensions as submitted to one of the mentioned web sites by a reader: Length 672mm Width 549mm Height 520mm(with accessories), I can't seem to find 13B dimensions. As for reliability, that's a myth, if a rotary is treated well(not over-revved) and serviced by someone that knows what they're doing it will serve you well. A 20B can weigh between 320-770lbs depending on what you have attached to it(770lbs straight out of a luxury 4 door called the Cosmo). A 20B engine would fit easily in a Z engine bay, the only hassle might be the gearbox since it's in the middle of the engine instead of the bottom. Also, finding a computer to run it can be a problem too(but it has been solved). As for cost, we in Australia can get them for about US$4000. They're a great engine, very smooth and with a whole bunch of power, 400hp is incredibly easy to get, especially after you replace the twin turbo with one big turbo. Good reading: http://members.nbci.com/craigpage/INDEX.HTM Info on a LOT of rotary engines - read the whole bit on 20B engines, it's good. http://www.hitman.hm/rx7.htm 20B 1st-gen conversion http://www.formaz.com.au/current/formaz/news.htm One that I found while looking for 13B dimensions.

Guest Lucidstrife Posted August 13, 2004 Share Posted August 13, 2004 What would be alot of fun would be the R26B otherwise known as the 4 rotor Le Mans winner for the early 90's they banned rotories in Le Mans after this thing won. check this thing out. http://www.geocities.com/fdkaimember/r26b.html http://www.mymazdarotary.com/mazda_rotary_general/r26b/html/r26b_paper_html.htm Lucidstrife Quote Link to comment Share on other sites More sharing options...
mtcookson Posted August 13, 2004 Share Posted August 13, 2004 3 rotors are incredible... 4 rotors are absolutely insane. you can take 2 2 rotors to make a 4 rotor. a few people have done it before and those things are mean. a guy did that in a rx-7 and pushing over 500 hp normally aspirated! he was running low 10's in the 1/4 easily and was short shifting too.

tannji Posted August 13, 2004 Share Posted August 13, 2004 I was ( and back in a small prvate corner of my mind still am) considering grabbing an FC or FD RX7..... and one of the sites I still read is RX7clubdotcom.... has its share of people we try to avoid, but not as bad as some of our sister Z sites. There are even a couple of LS1 Rexes there, as well as A GN7 . Good info, good stickies, and some very knowledgeable peeps. If anyone needs a rebuilt rotary engine, search there for Rotary Revolution, great guy, would fit in here were he a Z-type. Quote Link to comment Share on other sites More sharing options...
Thaniel Posted August 17, 2004 Share Posted August 17, 2004 As for reliability, that's a myth, if a rotary is treated well(not over-revved) and serviced by someone that knows what they're doing it will serve you well. Go to any Rx-7 web site and do a search for "unflood" procedure etc. When is the last time your nissan flooded on you? The Mazda dealer explained the flooding fact of the Rx-7 to me soon after I bought the car. Also look for blown coolant seal and broken apex seal. Or just check the forsale section of any rx-7 site and you'll see the same. I drove my rx-7 the same way I drove any of my nissan cars. My pathy has 210,000 miles on it (original engine and trans). My rx-7 started blowing a coolant seal and then blew an apex seal at aprox 100,000 miles on the SECOND engine. I also rebuilt the trans. The car flooded more than a dozen times in the 10 years I owned it. I've never had any of my nissan engines flood..ever (I've had 2 200sx's, 2 maximas and a pathfinder) Rotaries are fun but they DO have reliablity issues.

Got to be different I guess. Quote Link to comment Share on other sites More sharing options...
NZeder Posted August 19, 2004 Share Posted August 19, 2004 Hi - my first post - excellent site BTW. F.Y.I The famed 20B is from the Mazda JC Cosmo I believe. The trible was an option in these cars only. Most were JDM (Jap Domestic Market) approx 9000 sold with only about 4000ish with the 20B optioned in. This = rare engine also explains the high $$$ for these units However would make a rare engine swap and very interesting . Here in New Zealand we get a lot of JDM imports so their might be the odd 20B here 8) no idea on the $$. Quote Link to comment Share on other sites More sharing options...
