Is it a good idea going rotary motor

[djaztek12]

hey guys new to the club i just bougt a 69 510 wagon an djust found out that the motor is shot and i was only running on 2 cylinders. just my luck ?lol lol. well heres my question to all of u if could help, well i can't use the same block cause it has severe cylinder damage. so i have friends that have rotary motors and i was thinking of going that route. please help i need to get my wagon running

if you are confortable rebuilding rotaries and constantly mopping upp leaking oil be all means put int he rotary

seriously, rotaries can make big power but they do tend to be leaky and not known for their lonjevity

by the way, the VG, CA, KA and SR are all fairly common swaps for the dime,and are traditional piston engines that you can have serviced at any shop. many shops will nto work on rotaries

Go ka or Lseries.

the rotary swap is coming along real good nice and, clean i will take plenty of pictures when its done. the swap was no big deal, it was easier the i though

p.s sorry for the spelling? lol lol

people only run into problems with rotarys when they treat them like piston engines. The first thing someone needs to do when they get a rotary is throw out the piston mindset and start from scratch. It has to be built different, treated different, and tuned different. I know a few guys running stock S4 rotaries that have over 250k on their 13b and are still showing 120psi on all 3 faces of each rotor.

Just rememberBIG oil cooler (rotaries expel 1/3 of the entire engine heat through the oil)keep lots of oil pressurekeep the oil jets supplied with oil or pre-mix your gasrun them richRedline them at least once a week... this doesn't sound normal for any engine, but if you don't beat the $hit out of them at least once a week carbon will build on the seals and you can throw reliability out the window.

Congrats on the Rotary Dime... go embarrass some piston engines

finally someone with good feedback .here are some pictures of the project, so you could see im not BS, is still not done. just take that in mine before you criticize me,and work. also im not a mechanic just a guy that likes own cars, and this is my first 510 project only major part of this project was to cut and flip and re-weld the crossmember, make the front motor mount ,and also the transmission mount. is almost there, just need a couple of more detail. I will post a link of the progress http://s928.photobucket.com/albums/ad121/alexruano/

Looks like it's coming along Great! Though I will say the weak point to any pre-FD rotary (no it's not the rotors, pfft) is the ignition system. The distributor idea just doesn't pan out as reliably on a rotary as on a piston engine. Some people like them, but I'd say at least visit a few RX-7 sites and look around for some options. With only 2 rotors it's usually fairly simple.

ok thanks i will do that

updates i got updates

yep is getting there.

Hey car looks great. Did you throw a 12a in there or a 13b motor, hopefully it's a 13b.
