I'm an owner of a 92 Miata and previously owned a 81 and 85 RX-7. I've been dying to get my hands on the 3rd generation RX-7. I just found one very close to where I live for $8000. It needs an engine rebuild. What would be the estimated cost for an engine rebuild and turbo rebuild also?

Also, what would the cost be for a brand new 13-B engine? Can they be bought throught Mazda still?

 

new? I don't think so. reman is like 2200? for engine alone if you have a core. a rebuild with a good core can be had for a little less or a little more depending on R&R price and whether or not they go to 3mm seals. 99spec turbos(somewhat improved over ours for ~20 more hp stock?) are what, 3200?. turbo rebuilds with good cores go from ~700 to ~2500 depending on how much they are upgraded.

remove and reinstall, 1-2k probably. boost guage; 50-150$ (if it doesn't have one).

 

Leave at least an extra grand in your budget on top of the engine cost for odds and ends.

 

i just sold my 94 with a blown motor to my freind. motor from mazda 2100.00, gaskets,coolant hoses,fuel hoses, oil metering lines,1 broken soleniod about 300.00 from mazda. clutch 400.00-500.00. down pipe 200.00. luckely no labor we do it ourselves. it gets very costly but the finished product is worth some good money.

 

A "new" motor is about $6500 for the parts, but that doesn't include assembly.
