hey



im doing a rebuild on a 20b at the moment and due to it dropping an apex seal i need a new housing and rotor, the other 2 housings are mint but due to the fact they have had 77,000km's use on them and im spending $1400 just on all new rotor seals and wanting this to be a build that will last shouls i replace all 3 housings together or would it be sweet to just replace the one.



thanks

i think that since you are building a 20b which i'm sure you want big power and longevity you should probably replace all 3 housings to get Maximum life from your engine. Although they may still look good and within spec a % of their useable life is gone so...just buy new ones.

I think Mazdatrix currently has the best price on em around 600 unless youre a member of mazdacomp in which case they're probably cheaper. check rhdjapan.com too they sell them for cheap sometimes!

I Know racing beat will cut you a good deal if youd like to have them ported/etc. their but unless you want them to do the port etc.. they probably wont. i dunno ...



good luck with your 20b!

yeah unless its really low miles, or really nice condition, i think you want to change all 3
