Yeah Ben, I remember that, maybe it is coming back to bite me,haha

I remain positive and look forward to getting it all done

Builder said my Haltech Platinum Pro ECU is happily running over 9000rpm with the standard ignition system.

There could be a problem with the cam sensor, it could be faulty ?

[breaker1845]

Many people have still had timing scatter issues with the Haltech Platinum Pro ECU and ended up going with a crank trigger kit to resolve the issue. Although expensive in some way, it is practically insurance for your motor at higher power builds when most of the time you want to be pushing the car hard and don't want to risk the timing scatter causing issues with a tightly tuned motor.

There is a really detailed thread on here about the issue somewhere, I'm sure someone can link you or you'll be able to search it .

And for what it's worth, a brand new CAS would be logical on a build like this if you aren't using a new one and no crank trigger kit.

[Nismo 3.2ish]

When the car goes back all of these possible causes will be checked out.

It is something else to look into, does it ever stop

Sounds like u got the short end of the straw, I hope you get it all sorted out soon.

Shit happens mate, all close to being done, went for a drive today, it is a fun car right now

If you have read the thread you know what I am doing is viewed by many as a dud and the HP level is crap. I was never after massive HP.

BUT if I wanted to, when I finish what I am doing I could work the head, different cams, a mad turbo , and an E85 tune = bigger HP top end and stuff my car up for me =

How the legality of using an older engine in your car?

I think that's the question.

??

Was that ever discussed when they were taking your money? ?

older engines are fine.

But, the emissions gear must be that of the car or engine, whichever is newer.

Eg, old v8 into new commodore, has to have Commodores emissions gear.

Ls1 into hq, has to have emissions gear from the car Ls1 came from.

Including the restrictor for unleaded petrol in the tank filler neck.

That was the rule a couple of years ago.

Don't know if still current.

[luke gtr]

I am sure just about anyone could have done a better job building this car than I have, but it is my car and I do not worry about the money being wasted, I am happy the way it is coming together, no problem

The car drives "much better" than it did as a 2.6 and once the changes are made it will be a very tough all rounder, quick and a beautiful R34GTR, what else could a bloke want

always will drive better.

The 30(or 32 in your case) provides the bottom end so desperately needed for daily driving.

It really does transform the car.

Soon find out Luke, trying to use the best components to keep it quiet and emissions correct and then I am going to have the car engineered when it is all finished, maybe throwing more $ away, but it will let me know what I have to look at changing.

Going to put a CAI pod cover, quality Cat and whatever else is recommended to get it right

If the performance suffers, so be it

[XGTRX]

Don't bother, just drive it. Straight through exhaust to optimize response with varex muffler to keep it quiet when you need to.

[XKLABA]

A varex muffler is a instant defect

Best just get good quality mufflers that don't need to be turned on and off

[XGTRX]

If they can prove that it is controlled from the cabin I believe. Needs to be able to easily change the noise emitted from the vehicle.

[Nismo 3.2ish]

From what I could find out , if you "can" change the DB of your muffler with a flick of a switch or whatever and it goes over the legal 90DB , it is illegal .

I think I have a good exhaust system as it was so much quieter when I had it installed, not sure how the 4" or 3.5" dump and the new 5" Venom Cat will all work in together, so I will wait to put a DB tester on and if possible an emission test before I have an engineer look at it.. Maybe I might have to change the muffler but I will wait before I start dumping parts and replacing them.

When I insured my car I included the modifications

[Hadouken]

It's going to be louder with a 4"dump mate

[Nismo 3.2ish]

It's going to be louder with a 4"dump mate

Yeah figured that

I have a feeling the bloke that had my car gutted the Cat and I am hoping the new one might quieten it down a bit ?

Maybe I will go with the 3.5" and all the way through and see how that goes ?

First I will wait until I get the car back from the repairs

[jangles]

Doesn't Racepace make a 'legal' db 4" system? even if it's only close, it's going to be subtle enough

[Nismo 3.2ish]

I reckon close may be about the best outcome ?

But when I am ready I will ask whoever is doing it, what should I do ?

[Blackkers]

I don't aim for legal anymore when it comes to exhaust. A friend of mine swapped back to the standard system in his S15 and only passed by 1dB.

bit of a joke really.

Rules I follow:

aim for quiet enough to not arouse police attention while idling at an RBT

Quiet enough to not wake the neighbors as they can report you to EPA using the new app

If you can't chat to your passenger while idling in traffic or cruising at 120 it's too loud.

Don't drive in the city on Friday or Saturday nights. Don't be so stupid as to cruise through Kings Cross

most importantly:

No. f**king. Cannons.

It is possible to have a quiet system that makes good power. External wastegate vented to atmosphere will help tremendously.

just out of curiosity would a thick walled exhaust pipe be quieter?
