The other thread was not very active so this is a new one to get more response. Headers can be done with dyno or track results.
The cost will be apx.$500-10people or less, $400 or less for 20 people and more than that maybe 300 ish. No promises yet, but if some one can save me the time and money of driving to Denver for exhaust manifolds I will cut the cost of your headers. DV8- you have first dibs. I know you have the precious. PM me for my address. I could use my car as the labrat but I would rather have it running for the time being.

thanks guys for your support!
kyle :)

Post below on how definite you are on buying so we can get the best rates. I need to give this man the bus. for his hookup!

Sweet! We have a meet prob Sat. afternoon or Sunday around noon. I will call Tnelson and we can talk about it. I just got the blow off valve on from the second trip back to Joule. It goes by the tb about 6inches from it. I will get better pics. The manifolds loop around from the back to the front. This is prob my lag problem, and my exhaust leaks is why I am taking those off and doing them myself with a much more efficient setup. I will get dynoed when I have time soon-I just kinda ran out of funds.

Laters, Kyle
like some people on this board would agree, if youre having trouble with funds then dont be afraid to ask for some help, im sure people are willing to contribute to a project like this even if it's not on their cars.

That is true DV8, but you should see the sized of my turbo and the piping. Ex. leaks are pretty bad so that just may be the only problem. If people want to contribute I will have dyno runs up in a jiffy! I have nothing against that.
Thanks for the suggestion!

hey kyle, if you wanna run it on a dyno, i can get you dyno runs cheap here. Like 40 bux for 3 pulls. and im sure chris could squeeze you in, he is usually not busy(yes i am on first name basis with my dyno guy)

There is always going to be some "lag" felt on a well sized turbo, especially with an automatic. If you size the turbo so small as to build boost from idle up, it will be well out of its efficiency range by the top of the rpm range. The best setup for performance is usually a compromise of the low end where the turbo runs at its peak efficiency range during the 2nd third to the end of the rpm range.

However if the lag is really bad it is most likely due to issues with the setup. The exhaust leaks are most likely the problem, and there could be a boost leak somewhere, check all the charge piping, ic, bov, wastegate, etc. It's one of the most common reasons for bad lag. Pretty stupid of Joule to not correct these issues for you?

Also once the AVC-R is hooked up and tuned properly, it should reduce lag quite a bit. It allows the wastegate diaphram to hold shut until peak set boost level is reached, reducing lag. It also has a duty cycle gain setting, to control how fast boost builds at different rpm.

Theres methods to reduce turbo lag. Thermal wrap on the exhaust manifolds/turbine, etc helps alot, bigger downpipe/exhaust, smaller charge pipes, smaller vacuum lines, setting the boost controller duty cycle correctly, if you have other engine management options you can set up a 2 step rev limit launch, play with timing, ignition cut & retard which is how the anti-lag feature on the aem ems works, by allowing unburnt fuel to ignite in the exhaust manifolds, increasing thermal energy and spooling the turbo up.

With your auto you can just try to brake torque off the line to build boost even before launch, that should get you off the line quicker.

The first thing I would do is fix your exhaust leaks, any boost leaks, get the avc-r tuned, and you should have good spool after this. Then go to the dyno and fine tune everything especially the A/F while you have a wideband available, and show us some nice numbers :)

Those sound like things that I can, and should do. I might take up the dyno oppertunity in OK but I have to talk to my gf first. I still need to find wiring for the AVCR for the legend-maybe the NSX diagram would work because there is nothing for the legend.

Thanks, Kyle

To hook up your AVC-R you need power, ground, TPS, TACH, and injector.

Here are all the manuals and diagrams for the AVC-R:

Here is a detailed write-up of installation:

Here are some ecu pinout diagrams of other Hondas:

Hmm now all you need to do is just find out which wires on your ecu pinout are TPS, RPM, and the injector one you need.

I was looking in the HELMS, couldn't find the ecu pinout. I'm sure someone here will be able to find it for you. I heard the Haynes manual has the ecu pinouts.

Did you take those silly pills DV8? Just Playin, How big is it? The turbo and piping too. :giggle: :giggle: I am still planing on going to parker...I will just be a matter of time and money. I might dyno as is then go back when the probs are fixed.

Peace, Kyle

MY MY MY, Jouole really slapped Kyle with a unplanned turbo kit. while i applaud the fact it was made i cannot belive that they actually ran the exhaust dump pipe under the engine. not to mention the intercooling piping around the radiator support. I hope the roads are better there than here because all that stuff would get crushed. Dont plan on slamming you car anytime soon.
