Turbo for sure.. what no boost controller, injectors, ECU or Air Flow Meter? These all affect pollution control (EPA laws).

Depending on what state you're in cops will try to defect A pillar gauges "because they are in a crash zone". Yeah not likely if you have a front air bag! and how about taxi's and cop cars (and who's on the road more?). Anyway have the line added to the cert.

Not sure on side mirrors and aftermarket tie rods, lower arms, traction and camber rods etc

rest should be ok.

suspension stuff engineer can sign off on it and over ride the rules but the exhust not under hes power that you have to deal with epa.

thats a relief.... sort of.

Theres nothing that comes with a ADR approved sticker on it if thats what you mean its bascially just up to you to make sure its 90db if you want it to be legal and pass, but doesnt really matter if it is or not because cops will report you on suspicion for exhuast sound as some people have been done on standard exhuast so theres not really a way to be 100 percent bullet proof on epa issues.

Also take into account the stock exhuast is basically the loudest you could have and be legal since it is around the 89db mark.

whats the approximate cost of an Engineering Certificate? If you became a member of a car club would that help alot in getting things approved , i mean if you say the car is used for limited use on road and the mods are for the track etc etc..

I think i read somewhere that we can go get it tested after installing the exhaust where they test for emission and sound rite? if that one pass...surely the cops wouldnt be THAT anal to book u if u have something to show that it was already tested?

also... are they crazy? stock exhaust and still book u?!?!? but i take it that u can contest it right?

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
