Picking up my GSX tomorrow...

[doubleclutch]

I thought I would share...

Just bought a 98 GSX for $5000

120K miles
New:
Clutch (master and slave cylinder on a machined flywheel)
brakes
timing belt and tensioner
water pump

Mods:
o2 housing
megan turbo back
MBC
some kind of non-recirculating BOV
lowering springs
intake
tubular exhaust manifold
short shifter


Needs a few things here and there but in pretty good shape.



MOST IMPORTANTLY, the car needs to pass emissions in two months but has nothing even close to a cat converter....any good was to get one worked into my megan turbo-back? Something high flow woould be nice but not neccessary.

Thanks!

You don't need cat for emission after year 95 just get like ecmlink or a way to trip the ob2 where they plug into and you can pass emissions.

 

[souleux]

You have that backwards, you don't need a cat prior to 95. He technically would need one. You can get a cat most muffler places should be able install it.

um no you got it backwords, all smog inespected vehichles are the year 1995 and prior that do sniffer tests through tailpipe.Anything after that will be ran through ob2 scan.

On a different note nice car hope you enjoy it and hope you get your emissions passed, kansas is not and emissions state so I don't have to worry about that so im not going to be any help

Um, no.
1995 and after get the obd2 AND sniffer.

Sorry bucko, i have lived in oregon and washington and when i owned an OBD-2 vehicle out there i was scanned AND sniffed.

Some stations are more lax in what policies they follow, and just because your local station does it one way doesn't mean they all do.

 

[clipto]

Well idk where yall getting emissions at I just passed 2 cars in oregon and 1 in washington and only the 1 of them my 95 talon I had had to do sniffer the rest where just obd2 scanned. Any car like 97- newer does not need sniffer.Yea probably california but that is a stuck up state you can't mod your car if your life depended on it.If have to do both I guess your state sucks but crumy have to do both wich only the sniffer would matter why waste time on ob2 scan if your sniffer passes that all that should matter.I know it's mostly different in every state but I was refering to his state.

 

[doubleclutch]

From what I understand in CT, if it throws a code they sniff...seeing as it has no cat it won't pass...can a normal shop weld stainless?

 

[buhay6]

is there anything good about California? All i hear is it sucks living there. But anyways that's a beaut you got yourself there man!

 

[whyadsm]

Good deal! Pretty similar to my car, when I bought it.

 

[nicholasramos]

Haha, California is about one bad politician away from being Nazi Germany....Soon they will just say "If your car goes faster than a Prius, it doesn't pass"

 

[sciondan]

Good luck with her, seems a bit high for that year and miles. I alway get the price down on cars with mods cause it's a clear sign it's been ran hard. You got to remember people are not moddin these cars to just baby them.

 

[Tiki2777]

Quick tip, unless he has been flashing that 98 ecu to compensate for the BOV (previous owner), then you NEED to get that BOV recirculated. The BOV is recirculated after the MAF, so you can't just vent to the atmosphere. This will cause some problems that you really don't need.

 

[doubleclutch]

Thanks good tip. I will work on getting it piped back in...probably just going for a 1g BOV if someone has one laying around..

After doing a little bit of searching...

What does a "crushed" / "uncrushed" 1g BOV mean and can I just bolt it onto the stock 2g location?

Also, what kind of problems are we talking? Major issues?

Crushing the bov is going to let it hold more boost. The flange is not the same as the 2g plastic one check out VR Speed Factory - Discount Import Performance Parts they got cheap fmic kit with bov and flanged ready to go or VR Speed Factory - Discount Import Performance Parts I really like there fmic kit.

I believe this is right and wrong at the same time. Let me explain, all vehicles manufactured after January 1st 1996 are equipped with an OBD2 port, as opposed to OBD1.

Our OBD1 cars (1g's) do not throw CEL's for the emissions systems. The cars that do throw CEL's for emissions are 2g's.

You are correct in saying that, for the most part, 1995 and older cars do not need a cat for emissions as they throw no CEL's, but for some reason Mitsubishi adopted OBD2 one year earlier than everyone else.

If you have a 1995 DSM and have ever went to the autoparts store to get a code scanned, chances are they brought out an OBD1 scanner, which didn't work, so they went and got their OBD2 scanner.

Basically, you have less air than you would while recirculating, so it runs rich in between shifts. This causing stalling problems, even stumbling etc. Some people have even had problems at an idle. Its just not a good idea unless you compensate for it. (if you want to hear the bov, just get a metal intake tube) It is definitely possible to vent if you tune for it though. Good luck with the new GSX (98's forever).

Uncrushed= regular 1g BOV
Crushed= modified diaphragm to hold more PSI (sometimes works, sometimes doesn't and ruins it, just make sure and check that they did it right, most of the time it is good though)

I know it's mostly different in every state but I was refering to his state.

How are you going to give advice on emissions testing in his state when you don't live anywhere near it?

As said, it ranges wildly from state to state, and even between testing stations policies followed can range wildly as well.

 

[GSLENK]

Lol all these replies about other places. He lives in CT, it says so under his name. I doubt he has to pass cali.

And I read on here that if you have evo scan, you can use that to trick the OBD2 only test facilities, just be careful that you have the correct values for factory correct options for dsm and not evos, or other cars in general.

I dont have time to search for the thread, but its been done. maybe someone remembers better than I do where it is.

Here is where to start, the rest is up to you.

I did not say 95 and older do not need cat's I said they "DO" need cats. Being that before obd2 was out they do sniffer tests so without a cat u can possibly not pass unless you got a real good tune without a cat but oviously if they just do obd2 plugin test you don't need a cat.

How are you going to give advice on emissions testing in his state when you don't live anywhere near it?

My friend lives there and he actually fails emissions and they still give him tags. So I mean as far as I know everyone I know there just has to plug into the ob2 reader but they are all 97-99 yeard and as long as its showing complete for everything like using ecmlink to trip it then your good.Also he is 98 so he has a flasable ecu that can make obd2 scanned emissions pass.

And that is exactly why i love no emissions testing. I could register my car with the exhaust sticking straight out of the hood and the dmv could care less.

 

[preludeachris]

recirculate that BOV and put a cat on it and call it a day .....that is all

 

[GSLENK]

This guy doenst sound like he even knows his own laws.
You have to know the rules to know how to cheat.
A really big pocketbook could buy you out of thinking in general, but if you had such a pocketbook, you probably would be ably to pass anyway, or buy a car that could pass.

On pre-obd2 you don't "need" a cat if your car can pass the sniffer without one.
On obd2 you dont need a cat if it can pass the obd2 reader without one.

If you have to pass a visual, then guess what, you better have something visual down there. does it have to be real? no, hence the 2 points above.

Same goes for egr and vac lines... if you can pass without em good. If not, bad.

etc... etc...

Sounds like you got 2 months to figure something out, if not i would seriousley reconsider picking up this car, if of course you havent already paid for it

Good luck

1g for the mah###kin win. I go historic in a year and a half and wont look back. If i do enough, I might even qualify for street rod.

I believe that magnaflow has a 50 state legal high flow catalytic converter should you still be looking for such a thing. If it passes in CA it'll pass everywhere else to include CT.
