I don't think that this belongs in the epa section of the vic forums, as i'm looking for opinions of ppls from past experiences.

I curious if my exhaust exceeds 90db. My set up in my R33- i'm running stock pipes from the turbo to cat- 3inch high flow cat (catsco)- 3inch turbo back exhaust (hakimoto [not sure on the spelling]).

Today I went and got the exhaust lifted to ensure that my car is legal ride height and they didn't have a db reader. I'm currently trying to tidy up any loose end to avoid and surprises further down the track, not really looking for fines either lol

If ppl have facts of this issue, i'm keen to hear your thoughts.

Thanks

well i just cleared my EPA last week. 3.5" dump which i then bolted a stock cat back exhaust onto and my reading was 87db

seeing as you have changed from the cat back there is no way you will be at 90db or under.

Two mufflers should be alright. It's a qualitative measure so I'll wait to hear the vid but you should be right. I've got one muffler and a hotdog, it's alot louder than stock and the cop didn't say anything about my exhaust when I got pulled over for inspection.

Where did you get your exhaust lifted? and what part can get tucked up?

i'm pretty clueless to this stuff..but last time I was at my mechanics getting other stuff made legal, i asked him if he had a wheel to measure ride height. The entire car was clear except the middle exhaust bit that hangs down right under where you sit, it just clips his measuring tool a little and gets stuck. is there anything that can be done about that or should i be looking at suspension, not exhaust?

You can get any part lifted up as long as there's enough space between the pipe and the chassis. They'll just put a small mandrel bend in either side of the part that is too low. Alternatively, if you have coilovers you can just raise the car a quarter of an inch lol.

Cheers Birds, I'll get onto that.. any recommendations of a place to do it though.

Peter where'd you do yours? And where are you heading to get the DB sorted out and tested? shouldn't a mechanic or a wide number of places have these? if so, i wouldn't mind knowing my own reading. keep us updated on the outcome.

Quiet alr33x you hellaflush fool.

Any exhaust place will be able to do it for you mate. Ringwood performance exhaust were pretty good when I got mine done there.

lol @ "Legalis", funny as name.

Its doubtful that if its aftermarket exhust it will pass the stock r33 cat back is pretty borderline to legal ranging form like 86-90 and thats real quiet so doubtful any aftermarket would pass , can come close though

      Blue/grey smoke after idle

      Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      R33 Fuel Pump & Brakes after alarm swap

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
