He built my 20b using all of his components and he reinforced and doweled the motor. I cant wait to have it up and running.

About 120psi, very nice. I would be interested to see what they do after 10k miles though. Is that a totally fresh engine not started or does it have some mileage on it?

TitaniumTT.. I will be doing a mileage writeup on their seals once my build is up and running.

Looking forward to seeing the results

yes,I agree . however, I have used quite a few of these housings in motor builds in the last couple years.no issues. similar compression results.cant see anything that can really go wrong. just removing a little material. plenty of apex height .after all, whens the last time we saw an apex seal wear down as to not make contact with the housing ? they break before then (oem ones at least).in any event, I have been quite happy with the housing service. saved several of my core housings.

fresh engine . basically it was a previous mazda reman with unknown mileage. had a blown apex seal. everything else was in nice shape.

Rumor has it they are still holding solid compression after 5,000 miles

Looks good, how's the pricing on these compared to new OEM housings?

Fendamonky · 04-15-2012, 06:39 PM

^ Hey, newblet... Did you bother reading that first post in the link I put up? Or did you just say "looks good" and move on? lol

(Hint: That very first post lists current price

)

Essentially they use a high speed buffer wheel to remove defects, seems like this could be done by other machine shops.
