I spoke to a muffler bloke this morning and he reckons 4" could stop the turbo spooling as early as it does now ??????

Just want it too run sweet , with no shit :woot:

Then find someone who knows what they are talking about.

Don't ever ask a muffler man for perfomance advise, especially that clown

The easier gases can get away from a turbo the faster they can get through a turbo making the turbo spool faster

You would think they would know something about exhaust if they are in the trade ?

So you would have to step it up from the back of the turbo to fit the 4" down pipe

Hate farking cars :)

All but one exhaust guy I have ever met has had no farking idea.

Their industry is full of old wives tales.

Go ask any exhaust bloke to make a set of headers, and once he is done ask him what rpm band they were built for and do they match the cam choice etc...

Yes, if you look closely mine has that done to it

Someone who knows what they are doing will be able to fabricate a dump pipe to cat setup for you easily.

But what that muffler guy said is absolute rubbish.

Joe just posted as I was typing, but yes you have to step it up if look back to his pictures he uploaded.

When is your car going back to crd pete?

They have a couple of weeks with some Motorsports commitments , so some time after that.

If I get a local bloke to do the 4" down pipe and the Cat, is there anything I should make sure they do, does the down pipe have to be coated ?

Would I be able to sell the down pipe, shit it is new :(

Unfortunatly that down pipe is just about useless pete.. Probably the only one I've seen where its stepped down straight away..

Maybe someone who needs a 3 inch dump could cut the start of the flange off but chances are slim that it would for someone else's set up :/

I coated mine to keep the heat out.. More $$ though

It looks like that but I wonder if it looks like that because it is right up on the bend and I think bends tend to take some size of tube, but ?

    • Thanks for posting, your engine bay looks tops. I'm fairly sure you posted the wrong video though, I think you were supposed to upload the one from your "private test road" where it's banging off the limiter with the gate open?
    • This is something to be careful of. I did a bit of digging on the NM35, as I spend a lot of time on near brand new cars and CANBus related stuff, which uses the same "OBD2" plug for a fair chunk of making my life easy. The NM35, does NOT support OBD2. The data pin is actually on Pin3, which is a manufacturer specific pin, and requires Consult3 to connect to the NM35. Your low voltage, is either because the NM35 doesn't have 12V to the constant power pin on the J1962 (OBD2) connector, OR, it is attempting the standard comms, (CanBus, K Line, etc) and can't see any voltage on those pins. Some people have had success accessing SOME data from the vehicle on OBD2 specification, using a module that supports KPW. My assumption, like Duncan has stated, it will likely actually be JOBD, where there is some cross over with the OBD2 and JOBD standards. Note, lots of "OBD2" dongles, do NOT support KPW, which is what you need for a lot of Japanese vehicles of this era (And even up until recent years!), EG, Subaru, Suzuki, etc.    The end of this thread is probably worth a read, as some people did find a way to get a display up in the NM35 recently, looks like someone implemented all the stuff needed to make it work. (The right protocols).  
    • Depending on the purpose of the car, and how much more fabbing you want to do, and what clearances you have, you could look to raise the motor, which will raise the front diff up. Likely would mean altering the chassis rails etc etc, hence the more fab work you'd need to do. However, this can create issues, not just in clearance with everything fitting under the bonnet, but you've also raised a LOT of weight up in the car, and this will DEFINITELY alter handling characteristics (But, so will how much weight you've already added to the front end). You'll also have to deal with the fact the gearbox to rear diff is now out of alignment too for the tail shaft, and alter the angle of the diff, or deal with a bit of potential vibration. Raising the motor an inch up, is effectively the same as making the whole car sit higher by not lowering it as far. So one inch higher motor, theoretically means you can drop the car an extra inch lower, and maintain the same angles in the CVs. Again, depends on the purpose of the car. If it's a just cruiser on the street car, maybe won't be an issue. If it's meant to be a time attack car, I can see you not wanting to raise the motor. This is just for you to ponder as an idea.
    • Have you not seen geospy.ai? It can now give GPS co ords to within a metre from a photo, even if it's a random photo you take inside. Supposedly at the moment only the government/law enforcement has access to that... Supposedly...
    • I've got the rear ones, they're certainly beefy. I need to take them to my driveshaft guru to check over, he's very fussy about the quality of components so I'll let you know if they are made of cheese by a blind man.   Are you in Australia? A mate just had a set of EN26 shafts made for his K20 Lotus by our fabricator which were quite cheap (compared to Driveshaft Shop) so if you can procure the CV's and draw what you need he'd make them for ~$800 for the pair.
