this is the part where the cats attached to the block/heads (sorry picture)

Nice. That's on a 7G AV6?

Details on the internals, please. Did you swap all the parts over from the J35, or did you retain some of the J32A3 parts? Can the J35 pistons clear the valves?

g35_sc

Yeah, it is a 7G AV6. My swap consists of the mdx block with cl type s pistons for valve clearance. That is pretty much it for the swap. Everything else is just extra stuff that i am having done to my car. The car acutally has been in the shop for 4 months, that is because my valve seasts had to be speacially made because no one made them for my car. The reason i need valve seats is because i cracked mine when i misshifted. If you guys want to read my thread on v6p.net, just click here

oh and my enigne is actually the j30a4. Serge (02av6) is the one that got me the block. He is the one that helped buy the right parts for my car.l We are looking probably anywhere in the 275 hp and 260 torque mark sae corrected, maybe even closer to 300 to the wheels because of my extra stuff. Are these numbers of 21 hp increase sae corrected. For right now, this will keep me content until those headers come out.

g35_sc

what would be cool is if they did indeed got rid of the cats like this guy

I had a brain fart. I asked you if it was on a 7G AV6, then asked if it worked on a J32A3. I, of course, meant the J30A4. Thanks for the correction.

And yeah, Serge also gave me advice when I was looking to do the swap. I haven't done it yet, but I hope to do it soon. I found a J35A7 with 4,000 miles on it for cheap, but I found out that the J35A7 crankshaft is too short for my J32A2. I kind of stopped looking for a J35 after that. If I run into an A4/A5, then I'll probably do the project.

Props on the swap, though. Good luck with the project and hope you get the seats fixed.

P.S. 275 hp at the crank or at the wheels?

subinf

im curious to see how the flange will look...its easy enough (well any good exhaust shop) can make the rest of the pipe for you, its just finding the right flange to work on the heads.

ohhh! i want one! i want one!!!

I am so in... I need these headers desperatly.

damnit, NOT HEADERS. DOWNPiPES!!!!!!

I am in as well.

WHY would you get rid of cats and make your computer nuts. When it comes down to it not to many people are going to elminate there cats on a new car like the Tl. Unless you are strictly race. The guy who ran the 24 endurance race made like 17who more with out cats if im not mistaken. we have cats and made more hmmmmmm. The motor needs some back pressure to peform correctly. At least for everyday driving. Str8 pipes is fo WOT which how many of us are really doing that.

blaze6257

theres was around the CELs that the no cats will throw, my race header on my RSX-S uses a casper o2-sim that dose something to the signal that the sensor is read and send the information to the computer that there is nothing wrong. or you can use a defouler, which just sets the sensor farther away and it wont read that your running too rich or what ever and it wont set off a CEL. plus cat and not cat can make a big differance.

theres alot of factors, back presure isnt that much of a issue with out the cats depending on the piping size of the header, it the collector was a 3" a 2.5 or even 2.25" exhaust could correct that back pressure issue, and you would lose a few lbs of trq.

SNS Performance

Ah the defouler, what us Sentra guys refer to as the ghetto sim 3000. Works great and only cost $5 for 2. Anyways chances are these cats are good, high flowing cats. I remember on the older Jeep Cherokees, if you gutted that cat it would make a world of difference, however on the Sentras eliminating the cat would only give 1-2whp.

Count Me In Looks Great Nice Job.

g35_sc

the numbers that you made, are they sae corrected? That is a big difference too. Also, what he and i are using are these. He had his car like that for awhile and no cel. I will let you guys know how my car does with the o2 simulators. It seems that i will be getting my car sometime this week, i believe wednesday. So give me a couple of weeks after that, so the car breaks in.

I remember when I had my CT headers installed on my TL-S ... I felt like I wasted about $850 until I got into the 5K rpm range.. then it pulled nicely... and it definitely shined on the track. There was little to no torque increase...


This 20lb-ft torque increase is pretty impressive.

mbwmn

when?

carlrx7

ebay has o2 simulators and for the accord at least you need a heater simulator as well, the simulators are from the bottom o2 sensors only.

downpipes!

blaze6257

depends on the car, the rsx-s makes a bit more with a test pipe in gains, but alot more in gain with a race header and k-pro tuning.

only issue that there might be are the emissions system and the no cats, dont know how it would react, some one should gut the cats on their stock system before installing this and see if it effects the car during running and start up

subinf

that, actually, would be the dumbest thing you could possibly do. do you have any idea how expensive the cats are??? it would be much easier to go to an exhaust shop (if you can find one willing) and have them at least cut out your cats and weld in pipe to see how the car runs. that way you dont destroy the oem cats. its a pain in the ass but you dont fuck up good catalytic converters.

invincible569

I think Blaze was on the right idea.. but subinf's idea sounds more realisitic. Cat's are definitely expensive.

blaze6257

that is ture but if your going to replace you whole header setup it dosent mattter much, no one will really buy a cat unless tey are in serious need and no one will be paying what msrp is which is almost 1000+. its not really like the aftermarket if so great for the TL if you got the header and installed it waht are you going to do with the oem part?

subinf

i would buy an extra set of oem cats. i dont know if carb will ever approve an aftermarket cat for the 04+ TL so just in case my cats fail outside of my warranty i would like to avoid paying for a set of new oem ones. granted if i wasnt in california it wouldnt be as big of a deal, but ive seen a lot of people with obd2 cars shit themselves when they find out how much dealer prices are on obd2 cats.

batm4n

Aren't those dyno numbers with the hi-flow cats in place? So the header/downpipe might not be the full reason why your getting a increase.

Any #'s with the stock cat in place? or has anyone hacked the stock cat off and replaced them solely with hi-flows?

subinf

did we ever get a name of the hi-flow cats that are going to be used? i know car sound makes a very good cat and its not terribly expensive.

g35_sc

i got mine punched out. As soon as i get my car running, which probably will be wednesday, we will see what's up. The reason i punched mine out is because i know people that work at my local honda junk yard and they can set me some oem ones aside for me later on if i need them.

av6ent

Sounds good, but why is it so hard to snap a pic . Common Nitro

g35_sc

i agree on that

JOES05tl

I second that, or third or whatever. Give us what we want, Give us what we need! Wheres those pics?

Nitrotiger

As i stated the ones on my car were not the finshed product. It was the prototype. So when the final project is done i will snap photo's. Why are you giving me grief no one else had done shit for us.

NFLblitze1

^^^ lol i love that smiley

invincible569

Hey now.. dont anyone mess with Nitro. He's your only connection to these headers.

Nitro, I think everyone is just excited and anxious. No one didnt mean any harm.

againstallodds1

yea good things come to ones that wait, patience. If nitro was to snap a pic of the prototype, im sure someone here will bash it. So wait for the final product, I rather see a picture of exactly what I am going to get on my car than an unfinished product. Nice smiley though

dtpjigzer

yeah, whatever he said. im just waiting for the product to be available so i can buy it and have more power to my car!

subinf

this might be more than i can ask for, but if i send two cats that i know will fit can the system still be made less the cost for cats?

MichaelBenz

iTrader: (2)

That sounds like wishful thinking! Sounds like you should just build your own set. You think they are gonna mess around with that? Would be rare if they did....too much room for probs there.....and why would you want to do this...if you have a problem...you know its going to be those cats you sent in, right and not the exhaust they made...right?

blktl1

I just spoke to Mike from E-shift. the total stage one setup is mostly just the replacement of the 3 cats. there is a bigger collector directly off of the block which was increased to 2.5 inches but the other piping will remain the same. the y pipe wil remain the same until their stage 2 kit is designed. the stage two will keep the 2 high flow cats and just complete the piping between the 1and 2nd to the third. this will make the y pipe collector much bigger. unfortunately he does not have any immediate plans to do this due to clearance issues. the piping that is routed under the oil pan and tranny is flattened for a reason and he does not want to mess with that. he said before any group buys the price will be around 950-1050.

zax123

950-1050? OUCH!!!! Way too rich for my blood.
