Just checked out your web page story on the KA head conversion for your L20B Turbo. A great report on the trials and errors to make it so much easier for the next traveller down this path. Couldn't get the last few photos. Are they up on the site?
Brilliant engineering work Zac! Tell us how it goes when you're regularly using the engine. In particular how the engine temp holds with the water jacket changes. How have you rerouted the oil return after welding the oil hole in the head? Dont worry about those uninformed persons who were more interested in the bolt in turbo power upgrades, the really knowledgable people would appreciate the innovation in your approach. ----- Original Message ----- From: "Zac Campbell" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, January 04, 2005 6:03 PM Subject: Re: L ain't dead, baby!
