OK I see now. Sorry not good with import heads yet. I am still use to V8 GM and Ford blocks and heads. I still have a lot to learn about import engines though. Just wondering anyone know were I can find some good reading about Honda Engines?
Silver-SI, i know where you are coming from. I've been around V8's all my life. My dad builds the engines for my cousin's late model stock car. About the reading material. I bought the Honda builders handbook by Joe Pettit at Books-a-Million. It was published back in 96, so it's kinda old school. But it explains(in detail) the popular B-series and the D-series Honda engines. It gives you a real insight into honda engines
wow, I think I'm learning something here :D I've never really understood much about the internals of the engine...I'm glad we have this post...good one! :D
Just to sum up and clarify. The A2 head has VTC (+/- 25deg) on the intake cams only, look on the left of the pics. These are hydraulically controlled mechs.
Intake/exhaust lobes are also clearly diff. One lobe on the A3 exhaust
and 2 lobes on the intake. A2 has 3 lobes per side.
Vtec engagement on the A2 engages @ 5800rpm stock, A3 @ 2200 rpm.

It looks like I'm going to just save my money and get a DC5R motor. And if I really want boost then...I'll just build it to handle the boost.
Okay, I'm really confused! I need to know a few things. One, Is there any special fabrication needed to get the A2 head to fit our block like you need to do with Ls/Vtec? 2nd, I will most likely use the stock ecu for now, when I get the type-s ecu, will Vtec kick in on the exhaust cam or will using the stock ecu mess something up? Lastly, why do you need to use a piggy back fuel system with stock ecu, and what would you use? Will a Apexi AFC do the trick? Any info would be great.
Thanks
WHAT THE PHUCK!!!!!??????
How did this post get sooooo far off track?
First off, ALL K SERIES MOTORS HAVE VARIABLE CAM TIMING ON THE INTAKE ONLY!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ONLY!!!!!!!
The exhaust gear is NON ADJUSTABLE!!!
CRV/Accord/Element and K20A3 motors only have Vtec on the intake side
TSX and K20A/K20A2 have "real" Vtec on both cams
The attached pics are mine from months ago, so if you have any question, please ask.
Trust me....

Yep, I know that. She' seen 8100 already but surely will not last long if sustained for hours on a road course
Jack (B18CXr). If you do raise the rev-limit to 8200, and because you are running a 2.4 short block. With the longer stroke and reving it to 8200 rpm the piston speed would be around 5100 feet per min. Without a seriously beefed up bottom-end all i can say is.. DUCK! Even the hi reving F20C1 S2000 motor at it's 9000 rpm. The piston speed is around 4900 fpm. But I'm sure you have allready taken this into consideration.

Yeah what he said.
I am gonna get my friends Type-s head soon...his ep3 Si was repoed! it sucks for him but I am gonna get the head from him!
I am gonna be the first street driven Si with the head swap!
I AM SOOO HAPPY! Sucks for my friend though:(
The first on EPhatch, but I don't think the first ever.I am gonna be the first street driven Si with the head swap!
I think a couple people have already done it, a couple of A&J's customers.
I am gonna accuse you of being a smartass.
Hahahahahah, I know I wont be the first....its ok:)
:D
How much for the head? Are you guys thinking you will look through the junk yards or buy from Honda or what? Let me know my best friend is doing this swap asap and need the head...
-eric
you think I am gonna tell or sell it to you, Hahahahah get your own head!
I aint lettin this one go !:D
Why don't you call Gude up and price their head upgrade. They have an K20A2 head/cams/ecu upgrade since last year. When I was researching parts last year, I sent an e-mail to Gude. They responded with the A2 package. Sorry, they didn't price quote me.
