200+HP K20A3 build part 2: building the VTEC killer cylinder head. 

Thank you man. I got my kid listening to punk already, so hopefully when they grow up they can appreciate my closet full of band shirts 😂

Thanks man, Glad you enjoyed the video and even better to see it inspire a build!

It's coming soon! I have been working hard to get everything together and prepare the chassis for the engine. Thanks for checking out the videos! Temperatures are currently in the negative by the time I get off work but by next week things will warm up and I can put out some new content

Thanks man!

Glad to hear that man! I have a new video coming out soon. I cant wait for it to hit the dyno either!!! Thank you for checking out the video and subscribing.

EXACTLY!! I also stuck an a2 prb oil pump in this motor as well and will be discussing that in my next video. With some porting on the a3 head or even a k24a1 head with the same cam and vtec killer setup as my a3 its possible to make great power on a budget still. If you were to port the k24a1 head as well it can flow a crazy amount of air. I think I'm going to grab a bare k24a1 head and make a video about porting it. That way after I show this setup on the dyno, I can swap heads and show the difference and power you can make for cheap.

Can you do the job for my A3 pls ?

Thank you! I ended up using the a3 cam gears. I believe the only difference between the a2 and a3 cam gears is that the vtc gear on the a2 cam gears has a larger degree it can be adjusted to. Thanks for checking out the video and feel free to ask any questions. I do my best to respond to everyone.

jdmjedi777 thanks for the quick reply! I just got a sick deal on a pair of A2 cams for $100 shipped and they look super clean. They don’t come with the A2 gears is why I asked. You rock.

@@RatherBeRestoring no problem at all! Always glad to help out.

Hey man I actually really appreciate that. I always do my best to respond to everyone and help them put so if you ever have any questions please feel free to ask. I'm working on more content! Have a video filmed already just need to edit all the footage. Again thank you and I hope you enjoy the future content!

I will have an updated video on the build soon. I have just been getting my ek hatch chassis ready for the motor this whole time

Yup you sure can

The more aggressive option would be the TSX cams. I know that with those its a bit tougher to get to idle and you have to be careful with your VTC angles but are capable of more power. I just put this setup on the dyno today and will be posting the dyno pulls and video soon!

@@jdmjedi777 nice! would you recommend getting k-pro if i swapped the cams?

@@BrandonBuiltVideos yes absolutely. You are going to have to run kpro for the cams.

Soon man! I'm working on getting my ek hatch fully prepped for the swap and everything good to go

Sounds like a great build to me. Just clay the pistons to check valve clearance and let her rip. Would love to know the results. Feel free to ask any questions you may have.

Yup! Running a set of Brian crower valve springs

@@jdmjedi777 thanks im gunna copy ur setup in a 97’ ek Coupe

@@sigcustomlures4777 no problem at all. Good luck on your build! I love this setup on my hatch. Sounds awesome and makes good power.

With this setup both sides always ride on the vtec lobe. It is possible to get a set of a2 intake rockers, switch the pins around and still allow vtec to work on the intake side.

You will need to bore the block out 1mm but the k24 pistons will fit on the k20 rods. I'm honestly not sure what your compression ratio would be or what your p2v clearance would be but it should work.

If I'm not mistaken though your compression ratio might actually drop.

@@jdmjedi777 the k24a2 pistons are 10.1 com. And the k20a3 is 9.1

@@jdmjedi777 I have a bunch of leftover parts from my k24a2 that I'm building and I no I can drop the cams and rockers to make it VTEC on both sides and I no the rsx bore is 87mm stock as well as the k24a2 which in theory should work with the pistons

@@knoxbom3274 k20 bore is 86mm k24 bore is 87mm. You will in fact need to bore the block 1mm for those pistons. Just because the k24a2 is 10 to 1 compression ratio doesn't mean that when you stick the k24 pistons in the k20a3 it will have the same compression ratio. K24 has a longer rod length. A longer rod alone without a taller compression height or dome height on the piston will create a higher compression ratio. You need to measure the compression height of the piston and figure out the dome heights. Then determine what cylinder head to run. If you stick with the k20a3 head you will actually end up with a higher compression ratio than with an a2 head because of the square combustion chamber. You will still need to clay the pistons especially if using the a3 head.

I'm working on the car as I type this comment actually! Been working real hard on the chassis and everything. I have a dyno reserved for the 27th and am trying to run the car at import face off in may.
