Because of the whole fake vtec idea behind the k20a3, i want to get a new head so i get true vtec and obviously the extra horses. I know the a2 head is basiclly bolt on but i have heard the tsx head also works. If it works, would i get more power out of the tsx head?? Which should i do?

Thanks guys

 

From everything I have heard you should just get the k20a2 swap. If putting a head on a k20a3 was as easy as the b16 head swap onto the old b18 we would have all done it.

 

bunch of views.....anyone have any other opinions???

i was under the impression that te a2 head bolts right up to the a3 block?

yeah, but also need the a2 ecu and a reprogram from what i hear or hondata

 

And, as was asked in my first dyno thread, you'd also need the higher compression to really make use of the new head.

On the other hand, if you boost that ******, the A2 head's extra breathability might be a good thing...

 

both heads will work fine.. Just depends on what you can find complete..

The tsx head will also need some minor things

 

Do the TSX head...poor mans 2006 Si motor. Then you can use the 06 Si/Euro Accord Type R intake manifold.


I can get you a TSX head if you want one...

Well im not looking to boost it, i want to go all motor. What would i have to do to increase the compression.

 

there is a little bit difference in compression but not much. It would be night and day between the 2 setups...

To increase compression, you would have to use different pistons bbut then it would be silly to use the k20a2 pistons with the oem rods since we already know that the k series rods are weak.... So then you are entering custom/fully built category...

Just do the type s/tsx head.

 

so do the head, with pistons, and rods, then i would need the headers, and intake manifold.....anything else?

 

it depends on your $$$ situation..

Ideally, it would be better to swap a whole TSX motor in there. This way you don;t have to deal with swapping heads and you can use 2.4L... but K pro is needed..

TSXed EP3s are really fast cars.

From less $$$ to more $$

-add type s/tsx head on k20a3 ($1200)

-swap TSX motor $2500

-swap k20a2 complete swap $3500 (- what you get for your swap)

- JDM K20a type r swap $5500

-k24a block with type s head and custom cams, rods, pistons... $6000-$13000

There are also other options like swapping a complete CRV motor or block, etc..

 

It just depends on your situation..

for example...

This cost me close to nothing... someone's junk... that took his CRV in a lake



After spending $5000 retail on it... it looks like this

 

well the cash flow is quite limited, so im looking to get the most power out of the least cash. So prolly my best bet would be the straight tsx or type s head. But still the question, pistons, rods, headers, and intake manifold.....anything else?

 

I don;t understand the question... pistons, rods headers? What are you asking?

i think he's asking what else he needs for a head swap.

what i'm planning on doing is getting a k24a2 motor and swapping that in. of course, it would cost several thousand, but because it's a stock motor, there is a step up in reliability. simple bolt on mods would make the car fun to drive.

in the short run, doing little things is cool. but in the long run, i figured that using up a k20a3 motor with the warranty then swapping in a motor would be more ideal. the a3 motor is a great motor to begin with. i'm still learning the limits of my car and this motor is quick enough for me. when i'm older and more skilled at driving, i'll get to enjoy the (hopefully) k24a2 that i want so badly

you should just save money and buy a whole motor because head swaps seem to be a pain in the **** in some cumstances. with the a2 head on the a3 block without the 6 speed tranny requires a fair amount of tunning to get you shifting in the "sweet spot" or even falling out of vtec while shifting close to redline. plus reliablility is another big plus of full motor, tranny, ecu ,axel swaps.

well how much for just the k24 block and type-s head?

 

the tsx head isnt built as "sporty" as the rsx i believe

yeah well, I'd take 200HP i-VTEC with 166ft-lb of torque versus 200HP i-VTEC with 140 something ft-lb of torque.

torque owns j00.

besides the bigger the motor, the higher the potential to make more power...with less money.

350 chevy block..300+HP ...$500 bux? homemade turbo kit...$1000. 450whp? easily achieved.

Yo man Im with this guy. Except the turbo. All Motor Set ups the whole way!!! Get that thing to rev to 9 grand with the 2.4 liter and your memories of the fake vtec will be long gone! May not be as impressive as the ITR, but you will have a very very nice car!

 

doesnt the tsx use a drive by wire throttle instead of normal throttle body. this may help you in your decision. a2 head is the prolly your best bet man.

Aight thanks man....i think ur the first person to actually give me an answer.....

 

02ep3 -

I IMed you about an RSX S head. Hope to hear back from you. I'm located pretty close to you, too.
