Doing the same......Im putting a 98 KA in my 89, building my 89 KA (SOHC) and boosting it.....For info purposes I'm not sure if you know about it or not but lotsa good info at
www.ka-t.org ......
Some of the fastest KA guys are there and its a fairly new forum so they are all still friendly as long as you know how to use the search button...
Hope to see you there as well....
