is it easier or even cheaper to just rebuild an engine or to start from sctrach and build up?

Plans would be a 13b with approx 300hp. Not to sure about the specifics, but figured 300 can be hit pretty easy, right?

thanks

cheaper too rebuild, that way you dont have to buy the front, intermediate and rear housings. and also each rotor housing is around 500 a piece. then you have to buy rotors and all the seals, youre already looking at 2,000+

most rebuild kits cost around 800-900. and it comes with everything you need to rebuild your motor and gaskets, and hopefully youd only have to replace 1 rotor housing if you blew a seal and it scratched up the housing, and so you could have a rebuilt motor if you do it yourself for under 1,500.

I dont know if this is the most reliable advice, but its mine, you should see what the other forum members say

300 hp is easy

thanks,

was also thinking does a company sell a stock rebuilt motor? I don't have a 13B to start from; or are the off the shelf rebuilds not that great, and one would be better to do it himself.

I'm mechanically incline, but havn't messed with a rotary yet, I figured pick up a few rebuild videos and see if I can do it, probably can, not too worried about it.

just wondering can I buy it rebuilt or find a core and rebuild it myself?

thanks again

Try to find a cheap engine and go from there, unless you got it like that, then just buy one built?

Thanks for the replies I appreciate it. So... would it be easier to find parts for a 12a or a 13b?

Given the 300hp cap off, is this attainable with the 12a, I'm figuring yes. Then what would be a good reason to use the 13b?

Is a 13b easier to find parts for? Aftermarket? Turbo?

Does $400-500 seem reasonable for a used 12a or 13b?

thanks again for the help.

what car is this going in? No 12A, go 13B if you want 300 rwhp. Starting from scratch is going to be extremely expensive. Buy a junk motor and send it to Mazda as a core......Ray at Malloy Mazda has the best prices around (1888-533-3400). Remans are now up to 2500ish dollars.

The best thing you can do is buy a blown motor FD (there are a few out there, hehe) and begin your project.
