ok.. wikipedia says theres two versions of the a20a3. one being the 114hp version and the other being 122hp.. how do you know which one you have? wiki says that the 88-89 accords have the 12-valve 122hp engine and the 86-87 have 114hp but doesnt say the valves
i have an 87 and it says 12 valve on the intake manifold.. do i have the 122hp engine or the 114hp one?!?!

motors are almost identical just the 88-89 was tuned different
how would i tune mine to get 122hp? if its possible...

theres a few differences (manifolds etc..) pays to search

the intake manidolf and exhuast manifolds were diffrent and mayby ECU

so manifold swaps would do the trick? awesome.. thanks guys ill look into it

it'll be more than just that if you do the intake mani to. it has a couple extra pieces/sensors on it. Iacv dual, stage intake. hell maybee it's just those two things. but to control them you'll need the ecu/black box as well. but with just the exhaust mani you'd just have to plug up an extra o2 hole

if you want something better i would just upgrade all together.

alright.. intake mani is out of the question haha.. so what do you guys think of this?
head port/polish and exhaust mani? worth it?

Port & Polish and a Header make the most sense
2004-2011?
awesome.. thats what ill most likely do.. any ideas of hp gain?

so am i looking at a 33hp gain?

I thought one of the bigger differences was the cam...
That's why i specifically asked for an 88-89 EFI engine.
i could swap the engine for one from an 88-89 year accord but then ill have to change the black box and/or ecu... right?

An engine swap for 8 hp? Surely there are easier ways.

you'll have to rewire the main harness on the drivers side of the engine to take the new plug and run wires for the iacv. i just got done doing this, unless you need a new engine it's not really going to be worth it. go for a better cam or an air filter if you havent yet.new plugs a ground kit a header can make that much difference, 8hp
ya the cam is different too i forgot that not much but it is.little more aggressive.
"Weight is relative to power like time is relative to speed"
well camming i dont really like because of the rougher unpredictable outcome.. but the headwork and exhaust manifold i want to do
but back to my original statement.. will i be looking at 33+/- hp gain with headwork and exhaust mani swap??
now you know what i mean

possibly if you do enough head work. port/polish, valves maybee even bigger valves, shave the head. with all that i'm sure you'd gain at least 30hp, only a dyno could tell for sure what the real outcome would be tho. if you've got an 88/89 parts car i'd say go for the intake too. the dual stage runners make a difference in the upper rpm's
"Weight is relative to power like time is relative to speed"
would i be able to dyno an automatic? ugh i hate auto but i have to wait for the trans swap..
as far as the intake swap.. what would i have to hook up for the runners to function at max capacity? sounds stupid but i want it to work good if i get it
-Tom

the dual intake runners on the b20a black top make quite a diff in the top end pul eh
think the secondaries open at 5k rpm and gives a wee vtec feeling i reacon
i got a k&n pod filter and it gives that vtec intake sound once the secondaries open
sounds cool at the very least and does give a nice smooth bottom end and mid range due to the long primaries and that xtra bit of top end once they open
tha a20a3 has 9.3:1 compression

would changing the compression mess with the motor?

You would have to mess with the motor to change the compression...
ya i know that but i was asking if it would alter the hp numbers or anything like it
