@@rsx_jgonza4310 I got kpro but just want to run the stock ecu for smog Check here in CA ecu tunes is a instant fail. Was curious if the check engine lit up

[@goldcountryruss7035]

@@ih94568 I'm in CA too and bought an '04 SI EP3 with a K24A2 & it still has the stock K20 ECU. It does smog and runs just ok with no CEL but lacks its full potential. I registered the car in my rural county so until the car is sold, it will not require any future smog testing. That said, I will indeed be doing something soon to control the intake cam & tuning, just not sure exactly what ecu I will end up with. I also want to install a S2000 oil pump, valve springs, and certainly raise rev limit. Not considering a traditional turbo but maybe a bit (6-8lb) of electric boost in the more distant future. The car is my daily driver and will never be raced but on my rural 2 lane country roads I need/want optimum power for 2nd & 3rd gear passing when the opportunity arises. More smiles per mile is my goal.

Great video. I have an 03 SI and was originally going to swap for a A2 but naybe ill just do a head swap. Looks to be a lot cheaper.

[@dominicrichardson5546]

I'm looking at doing this on a budget. Could I in theory do this head swap and also swap in the stock a2 ECU which would already have the correct tune and save myself money by not buying kpro? I'll probably get kpro down the line anyway but for now would the A2 ECU work in a pinch?

[@quinton7854]

thought it was so funny that you were showing the lobes, and saying even the D series has more lobes haha, goes to show the k20a3 was not a great thought after the k20a2... crazy a simple head swap and you can see vtec, i hate that they didnt let us have vtec in the a3, or just a shitty version on vtec

[@supebeans]

I have a k20z1 currently that I spun a rod bearing on. My buddy is selling me a k20a3 for dirt cheap. I’m wondering if this same process would work for putting the z1 head on the a3

[@mattszpakut5588]

Pretty sure it isn’t as straight forward as this. But I’m decently certain it should be very similar, just a few more extra steps. Definitely look at forums and see how other people have done it.

[@franciscolozada1059]

It's a 2.0 so it should be a direct fit, to my knowledge the issue is when you use the accord and Honda element block on the k20 head since it will have piston to valve contact unless you switch out the piston and rods from a tsx or crv into the block.

I’m new to building cars and it’s become my passion. I have a ep3 hatch and I’m about to buy a a2 block from someone. If I put it on my a3 do I have to replace anything else or tune it afterwards or will it be fine to swap then drive?

[@alponching002]

Brother, it's me again. Was wondering if you think the k20a6 is tunable? Like i know the k20a2 is better. But limited variants are available here in the Philippines. So do you think the k20a6 can be tuned to reach 500-650hp daily driver?

[@LatinoAD]

For sure. Just lock the vtec in it. Get oem 3 lobe camshafts, get a second set of single oem exhaust roller rockers on the intake side like the exhaust side. Send it on ethanol or race gas for 500hp. They make rods and pistons for your engine. Maxpeedingrods makes H beam steel rods for the k20a3 which is basically the same as your k20a6. For pistons companies like; nippon, cp, wiseco, arias, JE. Nippon get oem spec k20a2 pistons to raise the compression and hello 500-600hp easy sir.

@Texas Honda Channel Hi! I’ve been searching high and low for answers on this (Reddit old forums etc) so Need answers or advice please gasoline leaking from manifold I have a 2002 Honda Civic (223,000km, LX, 1.7L) I have gasoline leaking out of the exhaust manifold does anyone know what the cause could be? Stuff that was already replaced: -replaced all 4 spark plugs -replaced Fuel injector (using codes) -put on a new manifold (last one had a crack in it) -Fuel Rail But it’s still leaking gasoline out my exhaust? Before replacing the list of part above it was -losing power/misfiring -white smoke out the tail pipe -engine vibrating/car vibrating -sounded like UEL headers on a Subaru -smelt like burning fuel All those issues have been resolved minus the gasoline leaking. I’ve searched high and low and have come across that maybe it’s possible the fuel pressure regulator? But I also resolved that too What do you guys think please help! thanks. :(

[@johnross8939]

Nice build. I like the K series engines. Help educate me. Why did you go for a K20 versus the K24? Was thinking of swapping a K24 into my Miata, but the oil pump conversion and deletion of the balance shaft turned me off. I rode in two swapped cars. Both vibrated like hell. Not any fun.

[@Vtec24]

Most likely reason for keeping the k20 is because it came in the car. The K20 is literally just a destroked K24, and the performance k20's make the same horsepower as the 24's (at higher rpm, and with less total tq). As for your miata; unless the oil pan must be modified you're more than welcome to keep the stock K24 balance shafts. The oil pump conversion allows you to rev the engine higher without cavitation. The type s or type r K20a/k20a2's come stock with no balance shafts because they both rev higher and the smaller stroke means they impart less vibration on the passengers. Most of all, if the vibration bothers you then you will have the most success by using near stock stiffness engine mounts.

[@johnross8939]

@Redstonemaster1324 thanks for your response. KMiata's kits to mount the K series engines in an NA or NB Miata require oil pump modifications, oil pump swap, and deletion of the balance shafts. For the racers and rally enthusiasts, engine vibrations are acceptable. If the engine dies, they'll just get another. For the daily user, a K swap into the Miata is unacceptable due to the extreme vibrations. I am looking at up to three other choices. Each has their merits. None results in vibration issues, and one can retain both AC and power steering.

[@Vtec24]

@@johnross8939 I will say I personally have a K20 with no balance shafts in my daily driver and even on stiff mounts the vibration is acceptable. I know some other options for the Miata include the Honda J series and ford ecotecs to name a couple. Certainly depends on your power goals. You may even consider an rb/jz swap if NVH is a major concern

Hey my guy, so this is actually the k20a3 engine which is also found in the RSX base model with 160hp? Ist it really possible to use the k20a2 head on this engine? Edit: is everything on engine block k20a3 stock? Like pistons, rods and oil pump? Please let me know, subscribed!!!

[@Leakyyy-]

You can honestly fit a lot of k series parts onto the a3, you can basically swap out everything and make it a k20a2. I believe type s oil pump is good for the a3

[@alfredohernandez7067]

La bomba de aceite de rsx A3 base y type s es la misma

[@acevedohiram]

The ep3 A3 has a balance shaft oil pump and, the rsx A3 and A2 have the same oil pump. The ep3 has the same intake manifold as the A2. You can also use the a2 pistons on the a3 rods. If you wanna swap a2 rods in, you need an a2 crank. Check out VHB engines. He covers almost everything you can do to the A3 in terms of building.
