Someone please assist me in making my car smog legal. IT is a 1998 Acura Integra GSR with 135k miles. It has a GReddy Turbo Kit with Front Mount Intercooler, all the doodads with the turbo, and a greddy evo exhaust. The kit i am told is 100% street legal but i failed everything! What can I do without returning the car back to stock to pass? Thanks!

Get a high flow racing cat because you probably don't have one, or you have a small cat and it can't handle all the exhaust thanks in part to the turbo and it allowed you to fail the smog test.

Its the intercooler. Are you in California?

do not get a high flow cat. theyre made more for performance and not function. just get a regular quality one (NOT high flow), and just take it off after the check. youll have a few less hp for the drive to the garage and back but itll be worth passing the test. that is, of course, if you dont already have a one.

"its the intercooler" wtf?

Yes I am in california. I have the original OEM Cat, never been changed. 4,000 miles on the turbo. Why would it be intercooler?

a turbocharger does not produce extra exhaust :screwy:


Oh and an intercooler would help emmisions more than hurt,

What conditions do they accually test emmissions? i live in Peoria IL and we don't have emmision testing. Is it just with the car at idle or what?

possbily clogged.. how many miles on the cat? any changes done to the kit?

Intercooler will not help. Call greddy and ask. they are carb legal untill you ad the intercooler. Also i work in a shop that does smog so dont asume it will help whem you do not know. Just call greddy they will tell you. Also if the intercooler was legal they would sell it in a kit. If you noticeit is sold seperatley.

thehube2: feel free to explain what an intercooler has to do with emissions.

hypsi87: turbo does produce more exhaust. more air in more air out.

actually thehube2 the intercooler WAS AND IS sold as part of the greddy kit, which is how i bought it, in a kit. The cat has 135k miles on it :o Can someone give me a straightforward answer on what it wouild take to pass emissions?

Yes here in california they bring your car up to 25 mph and take a reading of what comes out of your exhaust with a "sniffer." I am WAY off the charts on everything, and yes its a test only facility.

it could definately be your cat is clogged, id look into a new one. are there any other mods done to the kit such as upping the boost or changing fuel settings?

I don't need to call gredy. You might work in a shop where they test emissions, I work at a place where develop new ways to control emissions. I work in machine rescarch and devlopment at Catarpillar. Have you heard of a CAT. ACERT engine? It is the only diesel that passes emissions without the use of a EGR system and don't go whining to me saying "Oh its a diesel, it is different than a gas engine." As far as the EPA is concerned, it's all the same, both gas and diesel engines are tested the same way. Anyway, one of the things we did to decrease emissions was to cool the air charge down even more. CAT. ACERT engines use two intercoolers. One is water to air, and the other is air to air. Cooler aircharges are more dense, more dense air, the better it can burn the fuel, the better it can burn the fuel, the less emissions you have.

hypsi87: turbo does produce more exhaust. more air in more air out.

Well we where both kind of wrong on that. A turbocharger does not give your enigne more air (boost is the measurement of air you don't use.) A turbochargher increases the density of air that is being used. Its like taking all the air that is in the room you are sitting in now and squeezing it into the empty beer/soda can that is sitting next to you. Its still that same ammount of air, it is just more dense. So more dense air in more dense exhaust out. We where just thinking in different terms

Boost is at 7.8psi which is what it comes preset at. No other modifications have been done. OBX iridium spark plugs, walbro fuel pump, act clutch and flywheel kit, nothing else though.So you guys think its probably the cat? a few of my friends are recommending smog passing fluids. Whats your take on those?

dont know much about smog passing fluids. what are they supposed to do?

i still think its the cat though. the added air/fuel going through a stock 135k mile old cat just seems like it'd clog it up. plus the greddy kit probably keeps your afr's on the richer side to be safe

Ok, i think i will order a cat today, any specific brand or should i go with just oem? I might order a testpipe too because I am keeping the car. What kind? Also one mroe question im doing a type r 5 lug conversion but cant find the lug pattern anywhere!! I need some wider tires because i break traction all the way through 3rd.. any ideas? right now im running puny 16x7 motegis. Thanks fellas

Oh smog passing fluids, from what i hear, you empty a bottle of it into your gas tank and drive it around for a little, its supposed to clean out the carbon and all the gunk that builds up. My readings on my smog test were 119 for carbon and the most it can be is 9.. you think a brand new cat would really take care of my problem?

Before you get a new cat, take your car to any muffler shop and have them do a cat diagnostic. The drill a hole prior to the cat to see if it is cloged. But you might not want a tiny 20 gauge hole in your exhaust. Better check it your self if this is the case. If you take it off yourself, bang out the crap with a rubber mallet or hammer. This could help clear it.

Which part did your car fail. My car failed only by the timing. You might check that and put it to stock settings. And make sure your car is hot as hell before you test it. You get an even cleaner exhaust emmision that way.

just want to say that the greddy turbo kit does not come with an intercooler so im curious where u bought ur kit. anyways, remove anything thats not in the original kit-- http://www.greddy.com/
do a tune up, and maintenace such as fluching out ur old radiator fluid, change ur gas cap, and catalytic converter

and if it still fails because of the turbo kit, then it's time call greddy.

catco is a good quality brand. for a test pipe you can diy using jcwhitney parts or order one from kteller.com. try running some of that fluid through your engine, it cant hurt. also maybe clean out your intake and what not with some carbon cleaner from pep-boys or whereever

Or you can tune your car correctly

and who sad he didnt?

I apoligize for that post, I was in a bad mood and I don't usually do crap like that, but for some reason I did, I did not mean to disrespect him like that. I have just been dealing with a bunch of stupid people in the other forums on AF and I was in kill mode. Hope you understand and accept my apology :sorry:

lol, sometimes i feel the exact same way.
