86 RX-7 engien problems!

Got A problem...

I have an 86 RX-7 That I'm restoring, thing is it has 198,892 miles on it. I know that on this type of car the engien needs to be replaced after every 200,000 miles. But are there any other options that won't cost me $2,000 or more.

buy a used motor. used NA motors should be very cheap. JDM turbo motors are only ~$1000 too.

i've sold a running engine with 90 xxx miles for 550 cnd...
you just gotta search and wait for a deal
