I’m going to be rebuilding a 2nd Gen engine soon (don’t know if turbo or not) just for the experience. I love the engines but can’t have an Rx-7, it being a sports car = ridiculous insurance cost (im 16). What exist that will take a Wankel with out major custom modification. I’m aware that more that likely im outta luck. Any info concerning the rebuilding process or what to look for in a used engine would be a great help.

dude, insurance on a 2nd gen NA FC isnt that bad, i've had mine since i was 17 (and its relatively low).

can you re-word your question, i'm not sure i understand it.

I just need to know what to look for in a used engine. I heard they can blow up pretty quick, what can i look for to know its not a dud?

im 18 and my insurance is $80 a month

turn the flywheel and feel the pulses in the exhaust, or if its running do a compression test.

better yet just have it rebuilt, you'll be much better off.
