Read the 3rd post.

It has a link to the documentation. Sorry but I'm not going to give you the answer when it's clearly provided like that.

I did. Have read that document a hundred times and it doesn't have the answers I'm looking for. I have two pre-76 cars I'm planning on modifying. That document only goes back to '76. It'd be good to know what is legal before I go doing engine swaps and other, obvious to spot mods.

Just wondering whats the rules and regulations about having a surge tank, are they illegal full stop no matter where they are? I want to put mine where the spare tyre compartment is and probably replace that wood cover with a sheet metal cover which I will bolt there to cover it to try keep the smell down and also safety since the battery is in the boot. And also what are there restrictions for track scruitenering is it only not allowed to be in your boot if you have a hatch without a separete boot like on 180s?

Surge tanks are fine. For being street legal you have to obey the following:

As long as they are in a vented compartment, which can contain a fire if a fitting comes loose and drops/sprays fuel everywhere.

If you put your surge inside your boot, you must have a box surrounding it, ideally made of metal, with venting to the outside world.

Race application is different, and I wont comment as I have always had a 'street legal' car so never worried about scrutineers.

Cleared my Noise EPA on friday. Sunday did my gear box, Monday i get a FULL EPA letter. whistling.gifkill me.

Anyway, read almost all of the 43 pages, same questions popped up 20 times so im a bit nervous about asking this one... but i think ill fire away anyway...

My question is:

Clearly PFC and Injectors are not allowed, but i had a guy tell me that they didnt check and he got away, with everything else being stock. Has anyone else had similar experience where the guys didnt check ecu or do they usually check?

Ive pulled out my boost controller, pod, exhaust etc just wondering do i have ANY chance of should i not even try.

Full EPA? Don't risk it.

I've seen them open the ECU cover, unplug AFM's, use the consult port etc. All of which will give you away mate.

They also know the colour of stock injectors.

It's your call either way as it is totally luck of the draw.

Ohh not the answer i was hoping for... o well pull em out i guess.

Thx for superfast answer

Ive had full EPAs twice and they ripped out the kick panels checked ecu checked injectors and everything so its really a 30 dollar gamble so if you fail you have to pay 30 again to get it retested.

Might risk it just cos im lazy. Got plenty of time to go again and pass if, and when i fail. Lol

problem with being lazy is - it goes down on your file.

if you get pinned again, and again with the same mods... you better stock up on lube as they can cancel your rego and make the car unregisterable as just one possible outcome.

always pays to go in standard without one iota of ammunition for them

didnt think of it like that, oh well.

What is the best way to pass "CO" test..."idle" and "high idle"?. max is 4.5% i had 4.6 on idle and 5.8 on high idle.spank.gif

Got a letter in the mail about exhaust been too loud :( and need to take it for EPA!!!!!!!

question is, i have a pipe through the cat and what do i have to do to bring it back to normal?

Any help please??????

A stock GTR exhaust rarely passes - a clear example of how stupid the EPA laws are. I mean a 100% factory GTR, is over the limit. Full of shit this state.

So you'll need

1x factory cat

1x factory exhaust

1x baffle plate (just a metal plate with a dozen small holes drilled into it

Then you'll pass no problem

Thanks R31Nismoid

I wonder where i can get these now :(

bloody stupid law...when the compliance is done, do they do the exhaust sound test?

SSV did my car compliance when i first bought from them...

Got EPA a while back. might as well write up the story.

Got a letter in the mail, some EPA car bitched. I found it amusing considering i had just put on a new muffler that was quieter then my practically straight pipe i was running beforehand.

So, found a stock s14 exhaust and stock cat. The owner said the stock s14 had the original resonator replaced with something better. Awesome, every bit helps.

Replaced the exhausted, realized I had leaks coming from the front of the car. Fixed a large front pipe leak but I could now hear leaks coming from the engine bay.

Thought my manifold had cracked, only choice was to remove the entire turbo, check the manifold and all the gaskets.

Asked for an extensionand got a 1 week extension.

Removed everything and found that my last exhaust manifold stud had broken off in the head. Paid for something to drill out the stud.

Bought a standard manifold and started to put everything back on the car only to find I managed to damage the thread of the turbo oil line on the block cuz of the banjo bolt.

Asked the EPA for an extension and got a 2 week extension after writing a letter.

Tapped the damaged thread and bought a braided oil line. Fixed all the leaks between the exhaust sections.

830am on a saturday got a test.

Passed on 85db.

The tester draws a diagram of the exhaust and writes down what he thinks he standard or not. He had a question marked over my cat.

Tips to pass, stock system. 90db is quiet as. No leaks. Tester didn't check emission control systems.

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
