Anyone know any good sources on the inernet to find k20a3's. All the main ones only have the type s. I've pretty much given up the type s swap in favor of the more realistic K20a3. I hoping on being able to upgrade later or just build the a3. What would be involved in swapping a head. Just the head and ecu?? Would swapping the head be a better idea then just modifying the a3. Any advice would help.

 

k20a.org you can get a k20a3 with tranny for like 1200

 

If you get a k20a3 boost the hell out of it they love to be boosted.
