"...one of these things just isn't the same"

wait, does that make me gay?

Either way, I'm interested to see the results.

Not Gay... but possibly a Muppet.

4+2=6

Yes... 4 Headers for NA and 2 turbo headers.

But like the song said

"One of these things is not like the others"...

Come on Ernie and Burt sing with us...

[e30evolution]

This company manufactures 5 different designs of M20 headers 4 for e30 chassis + another 2 for turbocharging.

[DCColegrove]

Nah, those had real long primaries, and looked pretty good.

Yes, I'll probably run it in several different configurations

Awesome. Can't wait to see the results.

[DCColegrove]

Are you going to put a full exhaust behind it when you test it?

so are these the ones the guy tried to say were made in TX over on E30tech??

These are the same as Ireland was selling. Kinda a rip off of the Supersprint. not bad looking!

I'm not 100% but I'm pretty sure they are.

They sent them to me as a product sample... Not what you were thinking was it...

So...



A company in China sent me a sample of their headers, these are the same ones offered on eBay for dirt cheap (and for a little bit more from some of your favorite famous tuner shops), I posted about this a little while back and what everyone seemed to want was dyno specs...

That, I'm working on.

But this here is what I've got for you so far:

The Design:

They ripped off a good one, this I already knew.

The fit:

Oddly they pop right on there, as is expected the studs will need a touch of shortening (on the rear bank) in order for the nuts to clear easily.

One gripe, the clamping fittings will need to be fixed (slots opened and extended back a bit) because they will not tighten up.

One note here...This is important info for any semi complex install: Get everything in there before you tighten every thing up.

The Finish:

On the outside they look bitchin, the flanges are a little rough but on the inside...pretty damn rough, apparently the Chinese don't know it takes 2 bottles of gas to MIG headers (one for the inside of the pipes) Lots of "Marbles" and burning.

(If this was going on my car I'd "Mud Hone" the inside of the tubes...I would also shot peen the exterior shinny is nice but removing stress risers would help prevent cracking)

Overall: (so far)

Can't beat the price (especially on this one... they gave it to me) but I still will not sell or recommend these. They are not the Best Shit Ever. Without some work they will not perform well, the leftovers from welding will cause localized super-heating leading to cracks or burn through and the general material quality is suspect.


I am working on one of my buddies that has an engine dyno to let me play with this old M20 so I can get some solid numbers soon.
