I like how you did your math here. You calculated 30% of 370cc to come up with that 259cc like the KA actually comes with 370cc stock.. Just some correction stock KA are 270cc so to convert to E85 will be atleast %30 over stock so it would be additional 81cc on top of 270cc which would be what? 351cc if anything were a bit on the rich side. It's definitely not advisable for any high boost given the parts specs but should be able to handle just small amount to be fun..
Here's a vid of a similar spec running T3/T4, obviously larger injectors, maf it will hold on done right and properly tuned.
thanks boss, yea ima keep it so it gets the ka-t setup it deserves lol.
