Default China 64mm TB knock-off

I was trolling around and came across this. Very similar but likely not the same qualit. Still though, has anyone tried or even seen this?

It's already on Ebay as well at $96, has been for a couple weeks.

I'm convinced enough that it's 100% exactly the same part that i'm putting one on my DD.

Does a larger TB alleviate the effects of not having a square top?
Obviously it allows more flow into the intake manifold, but is it significant enough to make a difference?
Its much cheaper than a square top.

Mainly it keeps your throttle from breaking and killing your motor.

Interesting. I'm late to the party then. I was waiting to pick one up used just for safety's sake but this is intriquing.

Probably just changed the CNC code a touch and few different bolts n bearings. Likely see these popping onto cars soon.

I doubt they did that. My theory/hunch is that it's the same part made on a different line in the same factory, it's just not getting the last step of "put it in a Skunk2 box."

Skunk2 has been making this throttle for a loooonnnggggg time. It wasn't changed much for Miata application.

lol "changing things" is way too much effort for these places. the only things they actually "modify" are leaving off the previous companies logos and emblems.

or maybe it's not even that. maybe junk2 slaps their emblem on when these things arrive stateside, so in china these "knockoffs" are the actual part without even anything left off.

Yup, same as Junk2. I was somewhat seriously thinking about buying these in bulk on Alibaba as they're about $50 each there.

I'll wait until someone can compare it up close to the Junk2 TB. It would be tragic if I bought the cheap knockoff to prevent catastrophic engine failure and then the knockoff failed..
The Junk2 suddenly becomes appealing in the <$100 market. I find it mind boggling to buy a $250-300 TB and then have to dick with it to make it work properly; it's much more palatable for $80.

Just to clarify, what is the total set of fixes for a skunk 2 TB. I will upgrade to one of these over my epoxied stocker.

From what I have read and searched, the fixes for the skunk2 TB are redrilling the spring engagement hole so the throttle doesn't stick, and I read something about loctite, and some longer allen heads, but I didn't see it in once collective place, just spattered between build threads and whatnot.

Hmm. I didn't do anything to my junk2 aside from get slightly longer bolts, but sometimes it idles high. maybe I need to do that spring mod.

I hate overpaying for stuff. shoulda bought the knockoff haha

Minimum order quantity is 10 on aliexpress, buy a bunch and throw on a "Junk2" sticker on it and undercut OBX pricing.

OBX Billet Throttle Body Mazda Miata 99-05 1.8L 64mm BP-4W, BPT, BP-Z3 All | eBay

I only listed OBX since they're shipping from the states.

Great idea! I have a laser etcher at work, maybe we can engrave the mt.net logo on them and sell them on ebay for more than the Junk2 = PROFIT!

Lol, if you did the throttle body sticking mod, it probably would be better than a legit skunk2 tb.

Anyways, I went ahead and bought one for science. If someone that has a legit skunk2 TB we can compare dimensions/quality/bearing/etc. if you guys want.
