I am looking for non-turbo/supercharger ways of adding a little more power to my 2002 Accord V6. I have already done some minor supporting mods (cold air intake, full catback exhaust, performance spark plugs and O2 sensor), but I'm still looking for a little extra.
I've heard that larger fuel injectors can help but I'm not sure what size to get. I've also heard some mixed opinions on "direct ignition coils". Any advice at all would help, the cheaper the better.

 

Adding larger injectors won't give you any added power with a stock ECU. As far as direct ignition coils, you should already have it. 2002 Accord V6 has 6 individual coils, aka coil over plug ignition.

Next thing for you would be a set of headers and possibly an upgraded set of cams and a tune. $$$$

What is your budget and what are your goals?

 

Alright got it. Headers sounds good, I know how to do that, but I know next to nothing about upgrading cams and it's my daily car.
How much is a tune ? My budget is about $500 right now but cheaper is better. I know my header won't cost over $130, so that leaves me with about $400 more. Realistically my power goal is at least 30HP more, but even more would be awesome.
Does this header look okay ?

A tune will definitely run you over $500. Probably best to stick with the usual intake, headers and exhaust in this case.

I have no real experience with those headers. Never heard of the company. but for that price they are all pretty much the same quality. There are some that may require a bit of touch up on the welds. If you budget is $500 I would say do a tune up and spend a bit more on the exhaust.

 

Correct me if I am wrong, but a tune would require a different ECU and the software to make it possible to do the tune. This in itself would be something of an investment. And would not work with an automatic trans, which a Gen 6 Accord V6 would be.

 

I didn't want to get into specifics, and confuse anyone. That's why I simply stated that tuning alone would cost over $500, as this is his budget.

Are you telling me that there are no Honda V6 automatic vehicles out there that are tuned? I'm running a V6 automatic that has been tuned. Can even tune the shift points of the transmission. I'm not sure about the earlier ECU's but I know that KTuner works on some of the later V6 ECU/TCUs. I'm sure there could be an ECU swap from a TL/RL or later model Accord that could be done. $$$$....... but again, way over his budget!

 

Go on...

 

I have a 2012 Ridgeline with the J35Z5 V6 auto trans and some goodies that I have tuned using KTuner. But I will have to apologize. I was mistaken about the AT shift point tuning. KTuner does not have the functionality to tune the auto trans. It works on the Auto ECU, you just can't alter the TCU coding. I was getting tuning with HPtuners and KTuner mixed up. I have HPtuners running in my V6 Grand Am and have tuned the transmission shift points.

 

D'oH! Was getting all hot and heavy breathing over here...

 

Yeah, me too.
