Title: What do you make of these compression figures?
Post by: ramirez on February 13, 2011, 07:02:44 PM
Ok so after having some bad experiences with an FD3S in the past (not fully understanding them and checking it over fully) I am once again venturing into potential ownership.

The car I\'m interested in is a 1996 Type RS with 29k miles and the following compression figures :

FRONT ROTOR 8.5 / 8.3 / 8.4.
REAR ROTOR 8.6 / 8.5 / 8.3.

Please can you tell me what you make of these figures. They look nice and high but are they close enough to be a good sign of a wise purchase?

It\'s had a rebuild in Japan according to the advert.

Thanks Rex, yes that\'s one of my cars :chat. These tests were done on Friday afternoon ie 11/02/2011 and it was also serviced at the same time so it has run around 30 yards since the test and service.  I took photo\'s at the same time as it\'s always nice to see as i know it\'s quite easy to pull figures out of fresh air. The tester i use is a genuine Mazda compression tester, you can\'t get better than that!

they are extremely good figures, anything over 8\'s is very healthy :Thumbsup!

Easily removed and they are a personal taste thing but personally i like them and like many things look nicer in the flesh. I know when we\'ve had to replace PIA lights on the Evo\'s they\'ve cost an absolute fortune so it could make sense to keep them out safe & sound. Thanks for the nice comments to all of the above :cheers.
