I just got my 1st TSX in April of this last year, an 07 NBP NAVI with the rare 6pd manual. I want to do so much to my TSX... I just don't know where to start. Cosmetic wise... everyone has their own flavor which I don't expect or ask for any advice on, I'm looking for upgrades to beef up the handling and most importantly the POWER!!! I know a Cold Air is a good start, which I've done, its just not enough coming from an 05 RSX Type S which was much lighter. The TSX still feels a bit sluggish in the low to mid range RPMs compared the the lighter RSX Type S. I want the feeling of when I hit the gas whether I'm at 2500 RPMs in 2nd OR 6th... the car moves. Any ideas??? I tried to get a reflash from Hondata but they haven't cracked the 07's yet. If I had $4000 bucks to spend, I'd supercharge the damn thing but I don't... I'm looking for mods that I can get for a few hundred bucks at a time.

Also, I'd like to leave the exhaust alone if possible, I don't want any more attention drawn to me unless I bring it upon myself... I'm looking to build a sleeper here.

THANKS FOR ALL OF YOUR ADVICE AND IMPUT.

search is your friend

 

Like to replied to you on facebook, get a Rear Sway Bar

 

To make some gains, I suppose you could start off with headers, and a high flow cat. If you have the money to, search HYTECH products that heeltoe is starting to sell. They make the most gains out of any set-up at the moment, but cost you a pretty penny.

There are plenty things to do as far as handling goes, if you want to stiffin up the rear, just get a thicker RSB, and suspension, well thats to your preference. We have the Tires, Wheels and Suspension area for you to search on that for.


Search. Search.

 

performance wise, UR pulley set will help a bit (compared to exhaust or DC headers).

Does Sway Bar really improve cornering? cause i've installed it along with my Tein SS and Ingalls Camber, and i would like to experience some improvements... - -
i know and feel that the car became crazy stiff even on comfort setting on SS coilover...

maybe i drive local roads all the time.....time to go visit track or somethin

 

Don't think you technically need to upgrade your stock RSB if you dumped your car like yours hyung.

 

yea but shit is stiff as hell,
i started to compare my Tein Ss TSX to the new IS250 we have at home.
shiet....tsx is so stiff

 

So basically all you are telling me is that there is no other option power wise than either exhaust or a supercharger kit?

 

Has anyone heard of anything in the works for a reflash from Hondata on the 07's??? Do I have any other options besides Hondata?

 

lol wow, if you wanted a fast car i think the tsx was the wrong car for you brother...

 

You could make your car lighter.

Like take your back seats out

But yeah, if you wanted a fast car, I think you picked the wrong car too.

 

well i don't think its NOT a fast car... once I hit 5000 RPMs its pretty damn quick... which is great. its that lower to mid range RPM which the Hondata reflash would have helped that I feel is lacking right now.

I KNOW I picked the right car... I just might have picked the wrong year... an 06 sounds so good right now.

 

Yes, I would love for our TSXs to have more lower to mid range power, because
most of our every day driving is in that area...

This is off the topic, but are you a Purdue graduate?!

Noticed it on facebook, so was wondering

 

Not a grad... went there for a year for business and realized I didn't want to do that shit anymore... I go to UW now for education and a local tech college for Photography 20 hrs a semester total... its pretty fuckin rough, especially having a job on top but worth it... its how I pay for all of these nice toys I like to buy.

 

Actually, the Hondata reflash does nothing for low-end power. It's major advantage is the lowered VTEC point, which doesn't apply to the lower RPMs.

Also, if you want improved low-end power, you made the wrong choice going with a CAI. You lose a noticeable amount of power below 3k RPM. My advice would be to either go with a short ram intake, or find a Comptech Icebox somewhere.


I'm not sure why you'd think an 06 would be better than an 07 - the only difference between them is that 07s have the TPMS.

 

I think we wants a 06 because Hondata has a reflash for the 2006 models and not the 07 models.

 

Ah, good point...

 

On top of that you can go with the lighter pulley set (UR), lighter wheel tire combo and a header replacement.

 

Guys -- keep in mind he has a 6MT! I've got an Injen CAI and spend absolutely no time below 3k. Additionally, I've found the lower RPM "loss" is only temporary until the ECU learns after a few hard runs.

To the OP, I've got the mods listed in my sig and I'm able to be neck-and-neck with my former co-worker's '04 RSX with K-pro and exhaust. While I'm not sure if an '07 can swap the ECU from an 04/05, the "pet project" possibilities have just grown with a non-Hondata K-pro being available along with the Hytech system being released.

Do a search and you'll find the way to an all-motor, 300 WHP setup.

 

I don't see why an 07<->06 ECU swap wouldn't work. Same plumbing.

 

How and what am i looking for in this search thing?? Sorry I'm new to all of these forums and stuff.

They told me it wouldn't because there is new coding or something on the 07s which is why they haven't come out with the reflash yet. I'll ask them again but im going to look into this hytech thing too.

 

Here you go, I searched for threads with the word HYTECH in the title.
https://acurazine.com/forums/showthr...ghlight=Hytech


Hmmm. Hondata hasn't cracked the code of the 05 AT ECU either. What some people have done is to buy an 04 ECU, reflash it, and install it in their 05 AT TSX. So, my suggestion was to buy a 06 ECU, reflash it, and use it in your 07. (unless I'm not understanding your comment and there is some reason why an 07 ECU must be used).

 

Just because a large dia intake CAI such as Injen loses low end torque, don't assume the opposite must be true (short ram) to reduce low end loss.

 

Thanks for the help on the search. I actually just got off the phone with Hondata and they said I'm basically up shits creek without a paddle. I can't reflash an 07, I can't swap with an 06 and they don't seem to even know when they'll begin TRYING to crack the code on the 07's.

 

Yeah so after looking through that search and talking to heeltoe... i still need the hondata to be compatible with the 07.

guesss I'm still gonna have to wait on it.

should I buy headers for it in the meantime??? I mean am I going to see an significant enough gain from spending $500-$1000 on something like that or should I just wait and save for the reflash?

Is there any other option for gaining power besides going all out with a supercharger and how much of a gain would it be? I don't need 50+ hp... I would be totally happy with 20-25hp and something like 10 ft/lbs.

thanks to everyone whos been helpin me figure all this out.

I hate to break it to you but you'll need a reflash for the supercharger as well. Your best bet is to wait, patience has been rewarded in all cases but the 05 AT. In the meantime, you can still go for the intake, header swap as this will provide you with some marginal (in your terms) immediate improvements and still more improvement once the reflash is available.

The gain from a header swap will be there, but not the bang-for-the-buck that the hondata reflash will give. According to my spotty memory, you can expect a gain of around 7-10 HP from a header upgrade. Go to the Comptech website and you can look at their dyno. DC Header will give you roughly the same. The CT Icebox is good for 3-5 hp, the Injen for around 5-7 hp. You'll also feel the difference throughout the rev range (but particularly at low rpms) with the UR pullyes.

I think once you do these you'll be happy with the results.

 

Whoa -- 07 owners can't swap with '06's? That sucks.

In the meantime, you could still do some pretty good mods that should make your car much faster. If I was in the same predicament, I'd go with:
- Comptech or other shorty header
- CAI
- Hondata IMG
- Lightweight wheels & performance tires
- Aspec suspension or other
- short shifter

Those alone should make your car feel like an entirely different ride. And if you feel money burning a hole in your wallet, you can always do:
- RSX-S or ITR gear swaps (similar to my setup)
- LSD
- lightweight flywheel/clutch setup
- weight reduction project (carbon fiber hood, roof, & trunk, lightweight battery, etc)

And if Hondata does come out with a reflash, you can always sell some of those parts and switch them with a race header & VTC.

 

Thanks guys... i already have a CAI which I love. I will look into the headers and the Hondata IMG... I wanted to get that but figured it wouldn't make much of a difference so I was gonna wait until I got the reflash and just do it then at the same place... maybe I'll just get it done with the headers instead.
