I am considering the purchase of a 911 s engine on this site to swap for my 1.7. However, I would like to get an idea of the work involved to make this happen. Thank you in advance for your help.

Cheers,

John

With a used 911 engine, the key is to get an accurate leak-down test before you buy. That will tell you a lot. I got a previously rebuilt 2.7 from a friend, but he sold it at core price because he hadn't torn it down/checked or rebuilt it himself. Did the leak-down test myself and found the #s were bad.

Very glad I got it for $2k (complete engine from engine mounts, tins, flywheel, CIS system etc) because as my engine building friend started tearing it down, he could tell that even though it was rebuilt with case-savers it wasn't rebuilt totally correct and caused issues like a wobbly main bearing and a tight valve guide that caused a lot of damage. It's getting done right this time ($$$, even though we're re-coating the cyls as they were in good shape). It 'should' make 220hp and last a long time as long as I keep up on maintenance. Fingers crossed it does, because I won't want to take this wallet hit again!!!

Like everyone else said, it's a slippery slope and I hope it's worth it (IMG:style_emoticons/default/biggrin.gif)
You'll need to make sure your brakes and suspension are in good order, along with the other bits, like a tach conversion, oil lines etc.
I'm excited to see/hear about mb911's plans for more products, as his current offerings are a great help to the conversion and stock /6 914 community. People like him, naro914, Rich Johnson, 914 rubber and many others are really keeping these cars alive!
