ok so i just got a 02 civic si, im sure you all know they have the k20a3, and i was just looking for some ways to obviously make it perform better go faster yata yata yata.... i friend of mind did sugguest doing a head swap, for the k20a2 head.. like a rsx type s.. hence just all around better engine..
Now my ? is where can a get ahold of the k20a3... and what other valuable info do i need when it comes to doing this swap... COMPUTER. changes ect..

 

Honestly I would just go with aftermarket parts. Start searching sites that sell aftermarket parts and look at the ones that have dyno proven results that satisfy your needs. i.e Intake, header, exaust. And as far as computer ecu stuff goes check hondata.com. For reflashes etc, this will optimize your i-vtec window, if your going to spend the cash on parts go for aftermarket stuff, its better in most cases. With the combo I listed you could make like 40hp maybe more maybe less. But you would def see a difference.

You are right k20a2 is way better. But dont discredit th k20a3. You might want to look into a Greddy Turbo or The Jackson Racing Super Charger with the KPro ECU. I have been looking into this and showstoppers.com has a great deal on the Super CHarger with Kpro its like 2600 but well worth it. They also have a store sight on this website check them out really nice people.

Thanks for the info im still really interested in getting that k20a2 head which i heard that in order to get the head i would need to run kpro anyway. so maybe i could go with the turbo and the head, the only downfall ive heard is the turbos are obviously high maintainence for your car so ive been hesitant about running boost.. oh and about the k20a2 do you know how i might be able to get ahold of one? preferable new or just in reallly good shape. thanks

yes going turbo is very high maintainence, supercharging will be more reliable but you are limited in power compaired what a turbo system car do. as for the k20 a2 head id try ebay first

 

For the k20a2 check hmotorsonline.com I think for a complete swap its 4000 or so, check wrecked rsx's at salvage yards, ebay etc. My question is to you really have the cash for all this? Its going to cost alittle bit of money.

 

hmm yeah i dont plan on doing a full swap just a head so it wouldnt cost quite as much.. and on the cash issue this all gona take place within a year or two and im makeing some decent cash right now so i can afford it, hmm and as for the supercharger comment ive thought about it, if i did go supercharger... do you think my stock internals would be alright or would it overtime wear them down or do damage.?

A head swap is going to cost you about 2000 grand once all is said and done with out a KPRO. You would be better off with a Jackson Racing Super Charger. Supercharger.com has them for 2195, and Showstoppersusa.com hasit with Kpro for about 2600.

 

hmmm thanks ill check it out for sure.. so (cuban Racer) what all do you have done with your ep3?

i think if u get a2 swap on a3, i heard u need a k-pro with it too im planning to do a2 headswap with my base model as my final mod

 

well my Honda guru friends.. if i cant find a a2 head in my price range.. (because i really dont want to get something that was beat) what do you think about if a just got a more agressive set of cams for my a3? and im really.. thinking about that jackson supercharge(thanks to mister cuban) it just might take me a bit to save up for that..

 

or you could just rebuild the head....

 

could rebuild a k20a2, if i founf a beat one for a good price....anyone have a ruff estimate on a price to do that?
