: 2.1 head porting

3rd April 2010, 03:13 AM
I was going to port the 2.0 head but may be able to get a 2.1 head. im wondering if anyone knows of results in porting a 2.1 head, and if there are any CAUTIONS to consider when porting a saab head

have a read of this before you go porting a 2.1 head:


a T5/T7 head would be the better way to go. no need to port it, just modify it to fit the T16 in your C900 (its not a bolt on.. which is the only downside)
from memory the front of the head needs to be extended to match the timing cover, i have seen it done on here somewhere, a plate is welded onto the head and faced.

The only thing you want to do is open the exhaust pocket up a bit. Anything more would be counter productive.

There are lots of ways to fit the T7 head. Essentially there is a gap to cover up. Without covering the gap the engine oil will escape. So pretty simple to sort this out one way or another. There have been some very elaborate solutions over the years.
