Rx8 rebuild project car

Recommended Posts

Hello all new to this so forgive my mistakes...
Down to business I bought an 04 Mazda rx8 (192) 6 months ago needing engine work I knew it would be costly and troublesome but it is a project weekend car. As I am an apprentice mechanic I plan to rebuild myself. I am currently in the middle of it and in need of some advice I have done some research but need some help.
Now she broke an apex seal on the rear rotor and dragged it the housing is gone as is the rear rotor. My irons are marked so I'm looking into machining them, the question is can it be done and how much is OK to remove and mill, surface grind or hone is the question any input will be appreciated many thanks Hugh 😀

Welcome to IrishRotary Hughie! ;)

Whenever you've a minute throw up a post in the 'Introductions' section with some pics of your new rotary!

When you say they're marked, how marked & where? Have you any pics of the damage & have you measurements taken?

There are tolerances available on the rebuild videos people buy & elsewhere on the net if you have a Google around (a quick search found this on Racing Beat's website) - I've a set on paper somewhere I think but won't get a chance to upload them for a few days at least.

It can be done if you can find where to put a nitride coating back on them - most don't due to inaccessibility & cost so replacement irons/plates are usually the way people go.
