so i've decided to start modding the K24a4 for a 200whp target.

first thing that comes to mind is the Comptech (now CT Engineering) SC kit for the TSX. will this bolt right in? i gotta be dead sure as i'll be shipping this in from USA and a return or exchange is not really an option.

i'll also be using the e-manage ultimate for a piggyback. any bad reviews regarding this one?

i decided against KPro because i can't get TSX ECUs in my country  :-[

any help would be appreciated.

Yes it will. For the most part, everything engine related from the TSX will bolt on. As for the e-manage, there's mixed reviews floating around the internet. Why can't you get ahold of a TSX ECU if you can get ahold of the CTSC? You're better off with kpro anyway as it controls all engine parameters and will net you a better performing engine.

the CTSC is easier to get hold of as i order it straight out of CT's website and i pay via credit card.

not easy to get hold of the TSX ECU as there's no online store which sells them, and i had enough of eBay!

Have you tried looking in this thread (http://elitecm.net/forums/index.php?topic=20.0) for online dealers that may be able to help you out?

For the record, there's no way in hell I was going to suggest egay.

If I remember correctly you might have a problem with the idle air control valve. A notch needs to be cut in the mounting flange for the TB. I saw that the mounting flange in the installation guide looks like an 06+ intake manifold (TSX or ACCORD) instead of looking like an 03-05.

my mechanic can take care of all minor metal works which need to be sorted out.

my concern is if im gonna hit a major roadblock with parts fitment and adaptability.

also gotta do some research re: fuel injectors which will bolt on.

do you have the file of the installation manual?

im still doing further research on this viability of this one. in the meantime, i have the intake, headers, cams, and ems coming soon. :)

Ryan is correct.  Machining the SC inlet would be necessary for the IACV since the TSX doesn't have an IACV.  You could also use the RSX Type S inlet with a RSX Type S TB instead.  N/A cams will hurt your performance if you're planning on getting the SC.  You can make 200 whp with the SC alone. 

Greddy e-manage is a bad idea.  I haven't heard anything good about it.  You will make more power reliably using kpro.  Try contacting a Hondata dealer or Hondata directly to get kpro.  You don't need a TSX ECU to run kpro, but you will need a dual ECU harness to use a kpro ECU.  You can contact Cham to get a harness.

What country are you in?

will see what happens then, i'll take it one step at a time.

the boomslang harness will arrive anytime soon. too late to switch options i guess.

im based in manila, philippines.  :)

You'll end up spending less money doing it right the first time around.

will research on Hondata then.

re: TSX supercharger, should i be looking at the '04 A/T engine or something else?

It should all be the same.  Do you have an AT or a MT?

5AT.

Either kit will work.  I'm not sure why they have a different kit for one or the other.  There may be some small parts that are different. 

yeah i reckon, emailed CT Engineering and they gave me a general answer saying that the SC will fit, but some small parts may need to be modified.  ::)

Yeah.  Pretty much.  It's not a big deal.  I know that challenges that come into play when installing their SC on an Accord.

can you guys help dumb it down for me on what is better for an AT accord a supercharger or turbo? because i've been researching on how a turbo and supercharger works, but i'm still confused on what is better?

Neither if you like your transmission. People here prefer SC and a few guys have done it on their AT accords.

There's only one guy that I know of that SC'd his AT Accord.  I'm pretty sure his tranny is hurting now.  Of all the people that said they were going to do it, there are only 2 people that I know of that have actually supercharged their K24 Accords.  One AT and one MT.  I haven't heard from the AT guy lately, and he hasn't posted here in forever.  I've heard the MT is still around and kicking though.  

There was another guy back in the day on the old school g7a that slapped on a turbo kit on his AT Accord and he had all kinds of problems.  If you're seriously considering building a more powerful motor and keeping your AT, look into transmission upgrades before you do anything to the motor.  If it were me, I'd go with a SC for an AT.  There's a pretty big surge in power with a turbo, which isn't that great for an AT.

I could've swore there was another guy that did a SC on an MT. There was also one guy that slapped on a Greddy turbo kit onto his stock block Accord with MT and he blew it up since he decided he wanted to cheap out on his management. You know the guy Tim. He's a fan of egay.

Yeah, that guy got the turbo kit from the other dude that had it.  I'm not sure of a 3rd k24 Accord with a SC.  I remember back in the day, jim had a JRSC and Blinx had one too, but they both backed out for some reason.  I also know that ADI was planning on going with a sc, but his plans may have changed.  Also, icebox picked up an EP3 JRSC for super cheap, but decided not to go with it because the manifold sucks.

Adrian actually dropped the idea and I believe he's selling his parts. Not sure why but he did spend quite a bit on the car's current state.

Yes.  He already sold the cams and the Z3 head he had.

Off topic, but Adrian is selling his parts to fund another build.  Doesn't he have a K24A2, though, which the CTSC is built for?

I think he still has the A4. The A2 was for his MT swap to go with the blower. I'm pretty sure he was going to do a full blown/ all in one shot swap. I could be wrong though.

Yeah. You'd have to talk to him about that one.

wow that changes my whole perspective on getting a turbo on my AT but i was thinking of switching my AT into MT and also getting the rsx lighter flywheel but that's alot of money of my pocket but it may be worth it though because i am deciding to keep my car for 10 years or more, but a super charger doesnt look bad either but will it give me the same potential that a turbo can give me or even better?? I mean i will do my research but i can you guys give me your opinion? will i be able to keep putting more mods on my car even after the SC?

Tim is the guy to talk to about that.

Yea your right! Tim can you give me your opinion?

ya i still got the charger sitting in the garage, i will most likely install it since i already have it but it will no longer be a full blown build like i had planned before. i have had a k24a2 with bolt ons and kpro for the longest, when the a4 motor crapped out on me i did the swap.

i had planned on doing a full blown build like Tim did but i felt like i was spending way to much on one car so i bought a second car a VW MKV R32 and mods for that are expensive lolz (at least the ones i want  :D )so instead of going all out on the accord i sold some parts i had stashed up for the engine build (the rbc head, ips cams) still got a few extra stuff that i will get rid of (engine related, new bare block, tsx head,tsx crank) spare inspire front bumper, spare modulo front lip  ;D   

the charger i was thinking of selling it but i have it and i also have a tsx trans so i will most likely install it and be done with the accord as far as performance goes, no forged motor just a plain k24a2 with a charger at 9-10psi tops and tsx 6speed.  :)

I wish you had some parts that I wanted.  Although, the TSX crank has caught my interest.

Anyway, with a SC on a stock motor, you'll make some decent power and it will move.  Are there upgrades that can be done after installing a bolt on SC kit like the CT-E kit?  You bet your ass there are.  It all depends on how much you want to spend and how far you're willing to go with it.

The challenge with the roots style superchargers that come with the CT-E kits is that they generate a lot of heat.  I have seen my temperatures spike up to 250º at redline when doing a freeway pull on my old set up with a stock k24a2.  That is not safe for your motor.  One upgrade is to get an aftercooler from MercRacing or IMT and consider a water methanol injection kit to lower IAT's.  If you decide to go down the path of a SC, cooling upgrades are a high priority if not a must.  With my car, I ended up investing a lot into my cooling set up and it paid off.  Most people claim 360 hp is the most power you can make with an Eaton M62 supercharger on a K Series.  A lot of people also said I was wasting my time investing in my cooler system.  I proved them wrong and made more power than expected (with plans to do more upgrades) while effectively lowering my IAT's significantly.  As far as any other upgrades, there are plenty that we can discuss when the time is right.

If it were me, I'd consider doing the MT swap first.  That's really going to be the most difficult thing.  Then focus on getting your car running properly on K Pro before the SC set up.  The CT-E kit is a pretty straight forward bolt on set up that can be done in about a day. 

Tim- What are your thoughts with a CTSC on a K24A2 AT?

You'll end up damaging your tranny if it's left stock. I believe neoryan had tranny issues after he sc'd his at coupe. I don't know much about at's, but I do know that you'll want some sort of cooler for it. Heat destroys automatic transmissions.

Wow Tim awesome info thanks!!! that really does help me come to a conclusion, because first i want to make sure my car gets great maintenance and is running smooth for a car with 130,000 miles on it and then start working on the handling and tires and then move on to bolt-ons and then SC or Turbo, so basically i have a lot of time and i am willing to invest atleast 10K on upgrades on it. So then I may be a little too ahead of myself but i just want to know what im getting myself into if i choose either or and i want to know what to focus on first. but i hope i can still do all the bolt ons first before a SC because if i can do all of that as if i were to get a turbo like a SRI, Pulleys, Rsx intake manifold and more then that would be awesome but ill keep doing my research.


and Tim i hope im not asking much but can you unabbreviate the abbreviated mods??? I'm still learning

Ohhh and tim can you give me an estimate on how much you spent on all the cooling upgrades and the supercharger so that i can get a clue of how much i would be spending if i agreed on a SC?

Check out the bolt on section for your engine in here too, that's where I found the "how to" on the tsx manifold, and the AT shifter mod :) hopefully i'll get to them this year..

You're better off figuring out what your end goal is and build towards that. You may end up wasting money on things you don't need. A lot of stuff you would "bolt on" is irrelevant when you go with a sc or turbo (i.e. - pulleys, intake manifold, header, intake).

As for what I spent, it hard to say. I think I picked up the SC kit for about $1600-1800. The aftercooler for the manifold is about $400-500 depending on where you get it, heat exchanger is about $150, fans were about $50-60, the pump is about $125-200, reservoir was $150, then I spent about $200-300 on lines and fittings.

oh ok thanks tim your info is really helpful, ill keep doing my research, and im thinking of just going with a turbo since getting the SC i would have to switch my AT to a MT because having a MT in miami is a pain in the ass with all the traffic and traffic lights.

^Either or, you should invest in a MT. AT is not going to hold and will give you issues, if not give out. There's  traffic and lights everywhere :D, don't let that discourage you.

Truth. Manual is all I drove most of my driving life through Miami, San Fran, N.Y., and everywhere else I've lived. Hell, try driving a manual through haji filled streets in the middle east. THAT'S fun.

Turbo is worse for an AT than a SC would be. With a a supercharger, your power curve is smooth and linear because the supercharger is being spun by your engine. With a turbo, there is a jump in power when the turbo spools up. That will damage your transmission a lot faster than a supercharger.

Then i guess i should go with the MT swap, i guess im not being patient enough but you guys do have a good point i should get the MT then. I guess im just going to focus on repairing my car first, then maintenance and then performance and that should later on give me an idea on either getting a SC or Turbo. thanks guys

I'll also post up my profile and pics of my car now even though it's a mess right now it needs work.

Just a little food for thought.  I had my car for 4 years before I did a TSX tranny swap, 5 years before I installed a SC, 6 years before I did a TSX engine swap.  My car was on jack stands for a year and a half with no engine in it while I was building my motor and I just got it back on the road in November.  It's a slow road for people that aren't independently wealthy or have mommy and daddy buying all their parts.  Take your time to learn about what you want to do.  Don't cut corners of you will end up paying double down the road.  Let your car evolve over time.

Yea your right tim but no mommy and daddy dont pay for my parts and they never will this is all coming from my hard work and working mon-fri.! Im not in a rush with my car at all, the only thing im in a rush is repairing my car so that i can get to my job and and back since its the only car i have but i am patient with my car in the fact that i want to learn as i do everything and make my car evolve, im just in a rush to learn all of this and give my car the best so it can run clean, well maintained, with speed and effiency, im like a little kid locked up in a candy store with all this information out here for my 7th gen accord like i said i want to study engineering and maybe someday build my own engine someday and plus i dont even have time since im leaving to bootcamp for the marines in 5 months, but i totally agree with you tim.

You have no idea how difficult it was to read that without any punctuation or capitalization.  >:( That must be one of the longest run on sentences I've ever read. ???

Anyway, take your time and do it right the first time.  You'll end up saving money that way.

haha you got it tim.
