Performance mods:
Injen CAI
XS headers
Underdrive lightweight crank pulley
CT axleback
P2R TB spacer
P2R IM thermo spacer
Ingals ETD
MAF oil catch can


dyno was done without P2R spacers but now car run much better and im thinking about getting it dyno again

it was Dynopack

247WHP/210TQ



dont mind car was hella dirty

[ame=http://www.youtube.com/watch?v=SI-rzkRCFh4]YouTube - Acura CL Type S 6 SPD Dyno[/ame]


13,915s @ 101,4mph

[ame=http://www.youtube.com/watch?v=9w7KYXWIwmw]YouTube - Acura CL Type S 6 speed eTown 1/4 mile[/ame]

here is pic of my car



My plans are P&P IM and runners new 3.5" CAI

XLR8 75A motor mounts that are supposely on the way

maybe CTSC next year

im sure i forgot about something... suggestions are welcome i want to make this car run 13.7 now thats my new goal

Stock cat and mid pipe. But im planing to change that to highflow cat and 2.5" piping to axleback with magnaflow resonator. Im hoping for improvements because i dont want to loose the exhaust sound which i love.

change the midpipe, but your stock cat is already high flow from the factory so its not going to be much of an improvement compared to the loss of emissions performance and the smell of the exhaust.

Nice numbers/times man. You seem to be keep improving and that's what counts. I've been stock at the same ET/trap even with more mods! Good job, especially on the stock midpipe.

Both your ET and trap should improve if I'm not mistaken. Motor movement during launch and each shift should definitely hurt acceleration, especially for FWD vehicles. I think I have the same problem. Well, I think it's my tranny mount, not motor mounts. Wouldn't be surprised though.

well a couple things here...i dont care how big your exhaust is after the Catalytic there is a limit to how much power you will gain...also your exhaust is only as good as its smallest point ...and getting stiff motor mounts is probly the best thing you can do for this car

So you guys do not recommend swaping cats for high flow ? I belive that there is something in there to unlock.

Cat = pu$$y

I think you should do a custom header with a true 3" merge collector mated to a 3" exhaust. You'd probably gain 10-15whp from your current header collector/stock midpipe.

3" is to big. 2.5" will be perfectly fine. 3" is overkill. There are custom long tube headers that Paul makes but for me too pricey for now as long as i have those im happy with it. This car is my dd so going catless is not an option for me. Port n polish im and runners is next thing and mid pipe. I think i will be done by this point. If funds permit next year i'll put CTSC

Ah but 3" is perfect especially if you have semi-tentative plans to boost in the near future.

I don't know much about the CL-s exhaust from the factory, but I'd imagine a HFC would flow better. Paul is saying they flow well already from the factory. As long as it's 2.5in, you may be okay. But definitely get a midpipe that matches your header collector.

just give up bro he doesnt wanna be catless or 3"...dont worry i hav a feeling once he gets the mod bug and starts losing to people he will think differently...thats why i gutted the Fek outta my accord race car becuz the desire to be faster took me over! lol...oh n sonnick i gotta lil suprise for u buddy ...lets jus say bigger is better ...yea n the CL-S6 has the ability to make around 280+whp if modded properly 300+if tuned and thats N/A=No Boost

Street - if you're going 2.5" on the exhaust you need to upgrade the cat because stock is 2.25". What headers are you running? XS headers have a 2.5" collector and the CTs have a 2.25" collector.

Im still waiting for Paul to finish up the headers for me. Im hoping that it will allow me to break 300whp finally. Im really interested in the torque numbers more then anything though.

The Excellerate high flow cat is a nice piece, but expensive. Thats why I went with a universal 2.5" Magnaflow cat. Dont forget a resonator though if you dont want any drone.

And I need those damn mounts too.

i think im gonna go same route. What kind of cat was it ? and also what kind of resonator you had... your car is too quite... :P i'd love to keep the way it sounds but some more power would be nice

In the 1/8th what did you run? With my car mostly stock except for the single 3 inch exhaust I ran between 9.4-9.6 all night but my launch sucks!

Im currently at 294/275 at the wheels untuned with cracked headers. I was also running very rich - my AFRs were down into the low 11s, high 10s at WOT above ~5500rpm. I really need a tune but im waiting for someone to get the AEM EMS running properly first. I dont want to be the guinea pig. I havent made it to the track yet. Id like to go this season some time.



Street - I forget what model cat i got, but its one of the spun high flow cats Magnaflow offers. The resonator is a 28" Magnaflow IIRC. Dont know the part number on that either. The exhaust is loud when i want it to be, but there is zero drone.

Nice numbers. P2R has the AEM EMS running on their J32a2 Accord making over 300/270. You're not the guinea pig. You'd probably gain another 20whp/tq, if not more.

thats a nice dyno...a couple things though your air/fuels are only reading those rich numbers (which are inaccurate BTW) becuz the wideband thats attached to your tail pipe is off is not getting a true reading becuz like you said you have cracked headers so the exhaust is leaking out therefore reading improperly at the tailpipe....also the AEM EMS is designed for the automatic engine harness with a 6-speed tranny....there are only a few different sensors that need to be changed to run the AEM EMS on your car....i believe you need the following sensors/parts from and automatic V6 from the years 99-03: Crank position sensor and trigger wheel on the crankshaft, the cam position sensor and the trigger cam gear, and i think the water temp sensor as well...if you are a do-it-yourselfer this is no problem at all. you are already way ahead of the game with your car becuz you have the cable throttle and dont have to worry about the wiring mess that us 7th gen guys have to deal with....the AEM EMS is plug-and-play to your cars engine harness and interior harness...luky you!

BTW you should make between 330whp+ with the proper tune but the real gains are in the midrange where it counts

^What kind of dyno? Full spec sheet? What were you tuning with, since you didn't have AEM EMS?

The AFR reading was actually right from my wideband. My exhaust leak is at the flex pipe and the wideband is right before it, so the numbers should be pretty accurate.

In order for me to run the auto sensors, i need to swap the engine harness as well. And as far as being a guinea pig, I know there are a few cars running it. But I need to have a fully functioning gauge cluster which hasnt been confirmed yet and AEM cant/wont give us an answer. At the moment Im not 100% sure what other systems talk to the ecu (i.e. - hvac, abs, etc).

Current mods:
3.6l stroker
80mm throttle body
Full 2.5" exhaust
XS headers
Lightweight crank pulley
Clutchmasters stage 3 clutch w/ lightweight flywheel
Stock ecu

Those numbers are from a Land and Sea dyno in ~60* weather, low humidity.

You absolutely will not have a working cluster without electrical mods, i.e. signal modifiers for the speed sensors/tach. It is a matter of installing them, that is all.

Everything else will function completely normally, and on these cars, nothing other than AC runs through the ECU. You can even change the coolant temp/idle at which the AC is turned on/off.

In addition to the numerous j-swapped civics/tegs successfully running AEM as well as P2R, both myself and Tom (both J35s) are also successfully tuned on the EMS and we're both FI.

Edit: well mine blew on the dyno, so I suppose I can't say successful per se, but it had nothing to do with the fuel delivery/ECU. Haha.

You mention the AC runs through the ECU. Does that mean it doesnt work with the EMS? Thats a deal breaker for me as Im moving out to the desert later this year.
