Performance mods?

I'm just wondering what performance mods people have done that doesn't include a turbo, supercharger, or tearing down the engine. I'm just asking about a 2005-2011 tc if that matters

Think about your average entry level tC owner...

Typcially between the ages of 16-24.

What do most people in that age bracket want from their first car, or their first little "sporty" car that their parents didn't give them?

I'll answer it for you -- they want it to go fast. We live in a time now where apparantly your pride is measured on how fast your car can go. And let's be honest, although AutoX is big in most of our hearts here, it's not as popular as your run-of-the-mill everyday "drag race". I obviously use that term lightly, considering most of these kids consider going from 0-75 in between traffic lights to be "drag racing".

So, with all the considerations, I'd have to assume -- with probably an 85% accuracy rate, that the people coming here asking for "performance mods" are inquiring as to what will give them best results in the tasks above.

Just my .02

^That's because they don't know any better and don't know what "real" racing is.
I can easily agree with that.
I'm pretty sure this dude isn't asking for performance mods so he can go out and race his tC. If he was he probably would have mentioned that. He's looking for some non-too-pricey add-ons for the tC that will increase his horsepower a bit.

In my opinion, the price:power gain you get from them is not worth the $$$.

This thread got out of hand. Dude hasn't even been back in 5 days.

I reckon it all depends on what you consider "noticeable". Stock 2005-06 tC will dyno around 140whp. After I/H/E and possibly a pulley, I've seen them dyno 170whp. .
05-06 dynos at 125 according to all the numbers provided by Ptuning (Cant find the thread!). With I/H/E they can dyno at 140 maybe 150 if it's a high reading dyno...

One of the folks at club tC had I/E/H/Cams + pro tune and made 170. He said he was still having trouble against the civic si.

Do you have any dyno graphs of the 170hp tC?


A I/H/E tC is the same amount of acceleration and performance as a tC with the TRD supercharger on it. Talking about manual transmission that is. In fact I would put my money on the N/A tC to win. Seen that race plenty of times to know the outcome. .
I thought the S/C tC made 200HP?


A Supercharged tC with I/H/E added to it, is as quick or slightly quicker than a full bolt on 2006 Civic SI.

This i can believe... a full bolt-on 2006 si makes 170tq / 240HP so I dont see why they would'nt be well matched. :)

PTuning has a Dyno Dynamics which is one of the lowest reading dynos you can use (hence why I like them). I was speaking in terms of DynoJet numbers.

He sucks at driving.

That was 8yrs ago, so no.

They make 200whp, not 200hp (crank). So, an I/H/E TRD S/C tC is around 240whp (yes dyno confirmed).

Yea, I have a vid of this and they are dead even from a roll despite the higher rpms of the SI. If that were from a dig, I would put money on the tC every time.

To start...a 2011 tC is a 2nd gen. So you're talking 2005-2010.

As for "performance mods" like:
pulleys
intake
exhaust
header
midpipe
chips
etc
etc
etc

Won't net you any noticeable horsepower. COMIBINED you're looking at like 7-10 (and a very loud, hideous-sounding car). And that's not anything that you're going to notice or that is going to matter.

Simply put, if you want the tC to be a "fast car" you'll have to go forced induction like S/C or Turbo.
You can do some really easy, inexpensive things such as a Cold Air Intake, ebay has them for $88, better spark plugs, ignition coils and using at least mid grade gas has given me a nice little performance boost on my '09 tc.
I reckon it all depends on what you consider "noticeable". Stock 2005-06 tC will dyno around 140whp. After I/H/E and possibly a pulley, I've seen them dyno 170whp. I'd say that's decently noticeable both on the Butt dyno and the actual dyno. Cracking open the engine for N/A builds is a waste of time personally speaking, because you are going to spend the same amount of money for F/I but only just break over 200whp and with F/I you would break over 500whp with the right turbo setup.

An intake by itself, not noticeable. An exhaust by itself can be noticed in the mid-range. A header by itself, I doubt you will notice, don't know I never had just a header. All 3 together is definitely noticeable. But if you plan to go F/I in the future, then Intake and Header are two items you will just eventually sell anyway, so I didn't even bother purchasing them.
Don't forget the engine parts. Better plugs and ignition coils plus higher octane gas with a good intake will give you noticeable improved performance. I've seen it on my tc.
Gained 5hp...bhahaa...perhaps if you used ebay parts. I've done quite a bit with an N/A tC at a track (not drag strip). In terms of drag strip N/A is not the way to go on a car with a compression ratio of 9:6.1 to start off, but I did click a 14.7-14.8 with little N/A mods.

They make two LSD's for the tC, so you just get one installed anyway (which I have that too, forgot to add that to the list). The SI is just a little more expensive than a tC with a little more performance from the factory, but we mod the cars correct, so factory performance falls to the waste side when you start modding the car. If you make 300+whp and have a great setup, you can do a lot with that. Unless you just not that great of a driver then another "better from the factory car" that is less modded is going to be able to deal with the increased performance of your car.
I think you meant 9.6:1, when you were talking about compression ratio.

Nice info but I've noticed quite a difference in performance putting in a CAI and using mid grade gas only, in my '09 tC.
A wideband 02 sensor is good too. It will help your AFR and throttle response. It wont give you horsepower though, just like a pedal commander.
That's not true. Full exhaust you will notice a gain. I particularly noticed gains in the mid-range after a full exhaust on the tC.
Yes it is. I'm not going to argue with you, but I said it will NOT give you horsepower, But, it will help your AFR and give you better throttle response. If you don't believe me, look it up.
