They told me, it´s made in China and works only on LSX/R intake manifolds, so i will try to keep my LS3 gold plate runnin and stay at 90mm TB...

I've got the NW 102 DBW and I know they are notorious for being hard to tune but with a competent tuner and a little extra time they work with out a problem. They pop up on here every now and then in the for sale section for a decent price.

Yes, i know about the issue by tune of them, but what u mean is the origin Nick Williams 102 TB, right?

Why did someone sells this piece of art, is there something bigger/better on market i didn't know???

Nick williams is still one of the only DBW wire 102's you can get but they still have issues with boost so people usually end up selling them and moving to the boosted version or cable driven.

What are you guys using for a silicone coupler from the nw102 to the intake tube?

Which is the exact diam on the 102 TB to fit a elbow coupler, cant imagine a 4" is enough, cuz thats exactly 101.6mm...

The OD of the NW is just around 4.125. The 4 inch silicone tubing with stretch over the flange but you will need a 4.25, not just a 4 inch hose clamp.

Thanks!
I wasn't sure if it would stretch or not. Seems like sizes go from 4" to 4.5"

they are incredibly simple to tune.

Lots of places in china are notorious for getting US made products, reverse engineering them, and sticking them on the market for cheap.

it's been happening with a lot of other parts.

screw them, just for doing that, not just for lousy quality.

That's pretty misleading at best....... I would suggest a google search. If you are familiar with tuning them they are not as bad but not every tuner is equal and they can be a pain at times to get dialed in.

It's not misleading at all. I would suggest an in depth google search.

I mean, honestly, if your tune is already dialed in on an E40, the ECM already knows the idle airflow and startup airflow requirements. None of that will change. It just needs to know how big the TB is so it can translate those to a position value for a given airflow requirement.

if you get a dramatic increase in airfow because you switch to a bigger TB, i can imagine having to do some additional retuning.

i have read boosted guys have issues with NW102's, but i also read that has been corrected. I have no experience using it with boost.

I'm not going to argue do a search and you will see what I am referencing.

I had no issue at all tuning mine. why don't you post exactly what you're referring to?

There's that............. But I will leave it at that and not continue to drag this off topic.

that's cute.
