K20A Help

491 Views 6 Replies 3 Participants Last post by  LotusElise
I have a ep3 and I have a couple of questions about this motor I have. It’s stamped “k20a” on the block but it’s definitely not a type r engine. So why is it stamped k20a if it’s a economic version? Plus all other economical engines have the 2 lobe intake cam - 1 lobe exhaust cam right. But mine has a 3 lobe intake cam for some reason. And a 1 lobe exhaust cam. How does that work, doesn’t it need different rockers and adjustments for the extra cam on the intake side? I thought it was a k20a3 but it definitely isn’t.
