Overbore pistons

[TopCatGr58]

Hey Cnuk,

All I can tell you about the Cometic one is that when I put mine together the FIRST time, and then found bent valves, I was able to untorque it, fix it and then put it back together and retorque it without problems! Has held for 6 years now. It has my vote!

That's the beauty of the copper gaskets, too. You can use them over and over.

The problem (if it is a probloem) with the copper gaskets is that they are usually thinner than the composites making clearances tighter and raising compression slightly more.

There was a thread about a year or so ago that had a link to a company that will make a copper gasket any thickness you want. Do a search, and that may help! I am thinking of finding them for my project. I hope to bore it, but LOWER the compression for a turbo.

Got my gasket the other day.

Word to U.S. suppliers: Find ANY shipper other than UPS to ship parts to Canada!!!

UPS charges a 'brokerage' fee of $35CDN on top of any shipping or duty/taxes.

No other company chargers this.

My gasket cost $75 +$12 shipping, Plus $35 UPS and GST of 7%.

I found out about the UPS brokerage fee a few years back when I ordered about five bucks worth of nuts and bolts from McMAster Carr supply.

For small shipments, I have had better luck from a $$ standpoint having stuff sent via USPS. Once it gets here, Canada Post charges a much more reasonable handling fee. The downside to this way is the extraordinary length of time your shipment will sit at Canada Customs waiting for clearance. USPS gets it to Customs very fast, then Canda Post gets it to you from Customs very fast, but you can expect anywhere up to 2 to 3 weeks sitting at Canada Customs.

Most shipments I have had through USPS take a few days. The cellphoneshop.com usually gets thing shere in a week, tops!

I tried to get Cometic to use USPS but they only use UPS to ship here.
