Which motor is better and why
I have a question for you or anyone. I have and 02 Civic LX sedan auto. I am converting it to stick when I buy the motor. My question is what motor should I go with? K20A2 (220 HP) or K20A3 (190HP)? Also what would fit my car and if it does not, what sort of mods do I have to do? I love the read by the way.

K20A2 Pros:
-better flowing head
-metal intake manifold
-200bhp stock
-6-speed manual transmission
K20A2 Cons:
-Expensive
-The 3rd gear grind
-It costs a lot
-Did I mention 3rd gear grinds all the time? And no matter what you do, you can't fix it?
-The longblock, transmission, and PCM cost like $5k.
-You're going to grind the sh*t out of 3rd gear
K20A3 Pros:
-Cheap (someone back in college was selling a K20A3 longblock, transmission, and ecu for $300. Granted, he was borderline giving it away to get rid of it, but it goes to show what deals you can find for them)
-The transmission doesn't grind 3rd gear
K20A3 Cons:
-190bhp
-Doesn't flow as well as the A2
-5-speed transmission (even if it doesn't have the 3rd gear grind lol)
-The intake manifold is plastic. Granted, it's strong and lightweight, but you still have to live knowing you have a plastic intake manifold lol
-better flowing head
-metal intake manifold
-200bhp stock
-6-speed manual transmission

So, what do you think would be better? I mean now that you bring up the point of third gear grinding, I dont want to be replacing it every couple of years. Is this personal experience you have had with the K20A2? Thats crazy. I dont mind the k20a3 but i like the extra horsepower the k20a2 has stock.

So I talked to a friend of mine who said he had a similar experience with it grinding in 3rd gear, and when he put in a k24 it grinded in 4th gear. SO I am goin with the k20a3. What mods could you do to bump it up past the 200hp mark bsides exhaust, air intake, carbon fiber hood and trunk?
#7
carbon fiber hood and truck... dont add HP...
build the engine cams,pistons,shave the head and put thin head gasket (higher compression), turbo..

thats another thing. I want to add a turbo to it, but I want to get an emmision friendly one, as i live in cali, my car is a dd and smog it biannually. Would you happen to know companies?

You know I heard those two before. The only models edelbrock covers are the 00 and below. Greddy covers the SI motor which is the one I am going to put in. Is that bad?
