Hey guys. I have a crx torn apart (fully caged, kirkey seat, ready to go)in my garage that was going to get a built D series but lately ive been looking at a k series. There is only one K series in the city i live in and im willing to take on the task. (me and my dad basically have a machine shop in our garage).

Ive read through most of the faqs but i still have some questions. Sorry if i sound stupid Ive built multiple D series and B series cars but have never een touched one of these.

One of my main question is what is wrong with the k20a3? I know the bottom end has very low compression and the head does not flow as well. but if I had my sponsor dustin at performance porting build the a3 head and I do a mild NA built bottom end would it be comparable to the a2?

The plan was to build a motor that could be all motor on street and keep up with people but i could take to the track and spray a 150 shot at it and HOPEFULLY run 10s.

Is there anything weird about the a3 besides these that is a negative?

Thanks guys. Please no flames thats why i gave up on hondatech and came here.

The A3 is similar to the SOHC VTEC D Series in that it only has VTEC on the intake cam. Mix that with all the other short comings and you have alot to make up for...

Ive been reading a little more and it seems like that is very true. I know of a guy that lives very close to me that is selling a 02 accord k24 long block for 400. Will that work with the frank style build? and is there any Short comings of that short block?

If you are going to try and make any power with that motor you have a lot to buy. The only thing you are buying is the Block, Crank, Oil Pan, Timing Cover, Timing Chain, Chain Guides, Valve Cover, Coils, Water Pump, and Alternator.

I agree, But then again its only $400. I purchased my 05 k24a4 for $300 and its helped out alot. Bought a k20z1 head locally for $500. Thats like buying a complete k24a1. But then again, it all depends on what you want to do with the motor.

Dark, the motor that you want should be at least an a2 K series. Either the 20 or 24. Better internals to begin with will help you afford bolt ons. K-Pro is your ECU to get too.

Thanks guys this is really helping. I think im gonna part out the rest of my b series stuff and just buy a type s motor the way its looking.

:up: k20 is an easier swap to do is low on funds. If your going to build I'd say take the chance and go k24/k20. You might end up spending the same amount with aftermarket parts.
