Type-S head install done!

[myeverlovinsir]

I wanted to let you guys in on my swap. It's a power gainer and I will have dyno results in the new year. I know there are alot of base owners on here that wonder about this swap. I can say that it fits perfectly. I am near done now and will have the type-S ECU flashed this week. I am currently running the A3 Hondata ECU, 2200 rpm vtec and 7800rpm redline, and find that the power is much better from 3000rpm on. In the link you'll find vids that I posted only a few hours from the swap. My goal in doing this is to have the advantage of lower compression, which boost likes. It has been a clean and straight bolt on. Next step is the ITR tranny, cams, block guard and tunable ECU in Feb. Thanks for your interest.

Link works. :thumbsup:

Sounds good.

I'm curious though why you say the power is better from 3k rpm though. From what I hear, the milder cam profile for the a2 engine is very similar (lift, duration) to that of the a3.

In fact, dyno chart comparisons between the a2 and the a3 show that the base RSX a3 actually has better power from 3k-5k than the a2. Much of that is due to the dual-length intake manifold runners which I know the SI doesn't have, but the feel from 3k rpm should still be similar to your old setup, and the main difference should be felt after vtec.

[myeverlovinsir]

Yes, I also have proven on the dyno that my A3 pulled better than even the hondata A2 upto 6500rpms last year. Keep in mind I am running the A3 Hondata ECU. Vtec kicks in @ 2200 rpms and I am running off the high lobes at that point. There is some slight 'bog' with the engagement this low, but because I have hondata it is less pronounced. hth

[Go_Canes]

Yup, you gotta love the Hondata A3 program, though you should specify that it's the Hondata EP3 program since the RSX-A3 program can't compare.

How much in total did you spend for the whole set up? DIY?

[myeverlovinsir]

I spent less than 1K and DIY. Check the link! Dyno numbers are posted now.:p

[tofu]

for some reason i thought you had a rsx k20a3

what's the difference between the rsx k20a3 and the civic k20a3?
:dontknow:

and what would changing the k20a2 head mean for both of these?

This mod alone is worth every bit of it!!!! You guys in K20A3 RSX base model, get this head and you are type-S and with a little better tq. (I got up to 134ft-lbs in tq with the stock setup) and close to the same peak hp as a stock A2. with simple bolt ons. Of course the ideal building block is the k24 bar none!! Hasport is putting 325wph/225tq with this base. Again, that includes the Hondata tune and race header @ 9psi I recall. The K24 base is what means war at the track. 12-15psi is conservative.:wavey:

Ephatch is still down!!!! damn!

There is only one difference and that's the IM with it's dual runners. The RSX base ECU also uses pinouts for control of the runners. I was able to run my EP A3 hondata ECU with the new head. x-over occured at the stock 2200rpm. The A2 head swap is clean for both and it would be interesting to see a dyno plot with your manifold on the A2 head.
The trick here is to have runner control with the A2 ECU. I wonder if the programmable ECU could make that work? Hondata probably never thought of that one! lol. My guess is that you would have to switch to the A2 IM for full effect because the A2 ECU would not have control of them.

As for the auto tranny guys, I think you would be cornered with that ECU, unless hondata decides to make a unique ECU for that as well. I Don't think hondata even offers a tune for the auto tranny. Your plight is larger seeing as you would not only need to do the Head and ECU but also the tranny. hth;)

Ephatch has been down for the last three days. What the hell is going on there. I don't know what I will do without it :nervous:

Other than that, great you did the install. More guts than me :D

I have no clue. I am an EP enthusiast, although my engine cross-pollination makes this the next best thing. lol:nervous:

[myeverlovinsir]

It's up again!!! yeah!!! check the link for info. Thanks!:wavey:

The site is frickin acting up again. Errrrrrrrrrrrrrr.

[Spent198]

Wow, that last video showing the vtec kick is quite awsome. How much did you spend on this upgrade in full?

[James S]

He already said, Spent, earlier in the thread. A little less than $1,000.

[Spent198]

Okay, so I am trying to figure out what would be needed to do this swap. After reading both threads I am a bit confused. So, you would need a K20A2 head, 310cc injectors, 64mm TB, and K20A2 ECU?

[ariec]

You gain tons of horsepower but no torque at all?

well nevermind... it's basically a Type-S and they don't out torque the base anyways...

Shit if I could set this up for $1k, I'd buy the stuff right now.

Wasn't edo going to fabricate heads?

wow thats really promising for the base community, keep us all posted :thumbsup:

[goheels132]

For someone with an automatic, if they got a typeS head,IM, TB, and had their ecu flashed by hondata, would this work. Does the 6-speed type-S automatic that is sold outside the US have a single runner setup and if so would that ecu work with the typeS head on the rsx A3 to give a well working, more powerful car? Thanks

[D Fabulous]

if i can find a type-s/r head anywhere near where i live, i will do it!

not really.....a type-s puts down those numbers stock. You have to look at his mods along w/ the head swap. There is alot of extra work done to that car. None the less props for a job well done.

give a type-s the same mods and you'll be over 200whp.

What the hell are you talking about?

I'm sure the difference lies within the bottom end, he only has K20a3 pistons, therefore the compression is lower.

Even with the lower compression, these are good gains.

Maybe it was just someone messing around but I had heard that in canada they had an automatic type-S

[SpeeDemoN]

They were messing around.

[bunimoo]

or maybe an auto base with a type s badge =)

[webxfx]

is it something on my side - or does that link not work....

[NUNYA-RSX]

I can't get the link up, so what are the gains? and would you need just the A3 reflash, or would you need the A3 Kpro? I understand the Kpro would be more beneficial for self adjusting purposes, and that's what I would recommend. But would the reflash work as well?
