Where to get a compression tester ? Can't use a regular one correct?
 

Hey guys I need to do a compression test on a 13b , and am I correct that I need rotary specific tester and I can't use my normal tester to
Do this ... I swear I read somewhere you needed to buy
Can't find it again .... Sorry in advance !!!!

If you can spring for one... I really recommend you get a TR-01 Rotary Engine Compression Tester rotary tester. Tell em scrapp sent you...


AFAIK, using a normal tester:
You remove the valve at the end of the tester, (and pull the EFI fuse,) While holding the compression bleeder valve open, crank and watch the number that the needle keeps jumping to. Maybe 8 or so cranks to get an idea.

Awesome , basic tester it is!! I just can't spend 350$ right now .super stoked !

i gonna get a lot of flack for this but yes, you can use a regular one. however, it will not be accurate like the mazda one. with el cheapo, anything over 90psi is ok. 80s-70s iffy. the cheap one / regular will mostly tell you yay or nay. which for me works...
