Wtf!

 

Lol, well...you passed.

What kind of cat?

Also what was your timing? Having it set at the minimum can help bring down those numbers (14 deg i think?)

I'm going to be running a very similar setup later this year. Hopefully you get it figured out

 

Running a Catco Cat and timing is 16 degree.

Might just be these motors run rich and produce hella nox..

 

I dont know about that, I find that your 15mph pull and 25 mph pull in the nox/hc measurements are really different, which is kinda weird. You passed with flying colors at 25 mph in the nox levels.

 

you will melt it within a year. the oe ecu is tuned rich especially at WOT. find a used jdm cat if you're 2.5" or a used oe gsr cat if you have the factory collector on that edelbrock; before you wind up with a melted cat and partially blocked exhaust

experience speaking here

if you have to buy a new one from acura. the aftermarket cats simply can't handle the unburned fuel that the type r spits out

 

i haven't tried this but it runs against common logic. the later you introduce spark in the cycle the more unburned fuel you would have at the pipe. going to 18deg would bring on spark 4deg earlier which is that much more time to burn the fuel.

 

Good point. My NEW O2 Got fouled and went bed within a year..running a JDM ECU. So I guess this cat is not as effective as the OEM ITR.

 

I had the same prob on my new ITR it took me 6 times to pass even with a new magnaflow cat on it. The smogg guy had mercy on me and reved the car up real nice to super heat the cat and I passed barely on HC's I only had the prob at the 15mph test.

Im gonna go with SMS cat and go full 2.5 and if that doesnt work gonna just get a under the table smogg.

 

So we are not alone..

 

not alone at all. very common with aftermarket cats and the itr. all those POS aftermakret ceramic cats melt and don't clean up the exhaust nearly as well as oem.

the cat to have for a high flow exhaust is the OE jdm itr cat. it's 2.5" and won't fail in a year or less like the POS 100 dollar cats do

now for the bad part

your best bet at getting a jdm itr cat is either from hmotors or in canada. you need an importer who gets entire cars or at least front cuts. the going rate on a used jdm itr cat is 100-150 but i would not be surprised to that creep up as more and more people get wise to their value

come to think of it. how hard would it be to adapt an s2000 cat? they have a 2.5" collector as well

 

a little to late now..I have bought the catco..now if it doesn't last long enough then I will be most likely calling catco and telling them to give me a new cat. Time will only tell. I have a Catco on my 89 Civic for some time now..never had any problems. I paid $220 for the cat installed.

 

that's really expensive for one of those. that's a 70 dollar cat or if you get the magnaflow version like 140 for a direct bolt on.

the back side of the cat is where you need to be looking. mine took roughly one year before 3/4? of the honeycomb was melted together. front side still looked fine, all the damage was on the rear

 

I recently picked up a stock itr and had the same issue. Only 45,000 miles on the original motor. Is this normal for an itr?

 

Everything is expensive in CA!

 

yes. low tension rings, aggressive cams and a rich tune kill cats

but...it also keeps the engine alive when you'r spinning it north of 8k. running a little rich has a cooling effect in the combustion chamber and helps to prevent detonation under load

mail order and buy your own welder? if you're into cars you will need a welder sooner or later anyway

 

Not sure where you are located racebum, but here in CA, cats are now mandated to be serialized. It brought the cost of catalytic converters up dramatically. RPITA

yikes. that really sucks. i'm in oregon. we have places you can reg cars without any emissions testing. both my corvette and R swapped teg were never ran through emissions.

you guys have always had it the worst in CA

 

Yeah, we do. Here is my chart with OEM CAT.

 

Ok. The HC is still pretty high. I guess it is normal for these motors to barely pass.

What is your timing set for that test?

 

Honestly, This test was performed about 30-40 days before I purchased the caR, (about 2 years ago?) I assume the timing was 0plus or minus 1 whatever OEM specs are? There is no way for me to know. Keep in mind, the OEM cat had about 110k Miles on it at the time. Now I am closer to 145k Miles. I will probably start looking for a quality 98spec ITR replacement soon.

 

lot of cam duration, lot of overlap, the LSA is quite aggressive even on a stock itr cam. couple that with a rich tune and it's a motor that barely passes even when running well.

the worry with emissions should be apparent when you put some mileage on it and run up the mileage.

 

I'm planning to buy a brand new engine for my car too. How much was it for you? I recently bought 1998 Acura Integra Type R Shell. Any detail would help me out a lot. Thank You

 

I don't know..the previous owner bought the engine from the dealer and I bought it from him. I think he paid around $4100 for the long block only.

 

4000-4200 is going rate and you get no accessories, or a valve cover, oil pan, intake manifold, none of it

if you do wind up going this route i'll give you a package deal on a LOT of the parts you'll need. i have an itr starter, alternator, ps pump, iacv valve, tps sensor, coolant sensors, ait sensor. would sell it all for 200

that said your best bet would be to buy a jdm engine. a type r motor runs 2500 shipped from most places and you get all the little stuff

if you just have the shell i'd buy the full swap. gets you up and going around 3500

www.jdmdirectimport.com is a decent outfit
www.hmotorsonline.com is another but steve is a bit over priced with R parts

 

Wow this looks exactly like my smog test.

I also registered 60 on the HC when the max is 60! The car was much better at 25mph than it was at 15mph like yours as well!

In for the info!

I am fearing the next time I need to smog the car!

Did you get this engine BAR'd?
