hi everyone

i dont know if this is the right section to post this but yea...

durring the week when i was driving to work in my R32 gts-t i got pulled over from the cops. (i wasnt doin anything bad and my car is completely stock part from the cat back Exhaust.) anyways they were lookin over my car trying to pin sumthing on me. anyways they said my Exhaust is to loud and ill have to goto the EPA to get it tested etc..

my question is if i put my Silencer in the cannon and use low octane fuel (91 RON or lower) will this pass the EPA Emissions tests? also the cop said if i put the Silencer in ill have to get it welded up. or should i just but a Standard 1"inch Muffler just for that day?

post ur comments wat u think

cheers

bill

I reckon the 91ron or lower is not worth it cause you can cause some damage to your engine plus you will run richer aswell so hence make your chances of them pinning something on you even worse. The silencer would be fine the same cop wont be at the epa station so i believe it would be all good as i know people who have the bolted silencer and never had a prob.

Did the cop say you MUST GO TO EPA, or did he say a "licenced exhaust tester". Because if he is only giving you an EPA for noise then all you have to do is go down to the closest exhaust shop listed on the EPA noise letter and get it noise tested. And if you have to put a silencer in it MUST be welded in to pass, but sometimes if you know the guy some rules are bent :dry: .

IMO it's probably easier to swap to a stock exhaust for the test.

I also don't see how 91RON fuel is going to help with emissions.

chaning fuel does not alter emissions when the ECU is looking for over 100ron anyway

It'll be a test, just going to a licensed tester, not the EPA station itself.

Get it tested, see how loud it is

go from there

EPA is fun :(

belive it or not skylines run very low emitions

you'll pass emissions EASY

however noise is your problem...

bolting the silencer into the cannon is not good enough, when i failed noise at epa, i asked them if putting my silencer in there is good enough.. and they said no... only if it is completly welded in there.... and spot welding it a couple of times around the rim isnt good enough either!

you should be right... :)

all the cop said is that ill be getting a letter in the mail from the EPA to go for a test. i dont really want to weld up the silencer to my cannon it looks sh!t and it sounds G.A.Y, but when using 98+ ron doesnt it burn more fuel and create more emissions?

no way.. skylines are tuned for japanese fuel (like 104oct) so its fine.. emmisions shouldnt be your worry.. your allowed 5% carbon monoxcide or what ever it was.. i had a screwed 02 sensor and still only blew 1.6%

WAY under

you'll be fine

... with sound just make a baffel plate with a few holes in it and jam it between one fo your flanges

they rev skylines upto 4800rpm at epa and it cant exceed 90db

Not a problem. You just go down to a licensed epa exhaust shop. They will do the test. When you pass they give you a certificate, they keep one copy and send it to the epa saying you passed. Thats it.

DO what ash advised me to do. Get a mufler made up that decreases the diameter and just with a normal muffler. Lowered my car from 111DB to 89DB to just pass. And when u get home. Chuck the cannon back on :(

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.
