does any one know how good this manifold is??

i never heard about it before,so i ask u!

 

never seen that name before. the welds look good but the determining factor is the material they used in the type of steel and the thickness of the tubing walls.

Detailed Description
The tubular Neukin Motor Development turbo manifold has been sold around the world with great results.

The manifold will fit larger T4 turbos, equally spaced between the intake manifold and brake line. Designed on a 2nd gen 86-92 RX7 with the 13B. This is a high flowing manifold unlike anything on the market. The runners are 2" size unlike most of Neukin manifolds that run a 1.5. The manifold has a lifetime warranty against cracks.

i still dont know about it.i wanna see if any one out there is using it?

 

I think I seen one just like that on ebay not too long ago. but I don't think it had a $500 price, I belive it was around $329 plus shipping. Nice looking manifold though.

 

I'm going to play devil's advocate on this one...

There is no such thing as "rust free" stainless steel.
Stainless steel is rust resistant.
It's going to start to oxidize, especially with the harsh environment of the rotary engine heat.

I question why they didn't mention what type of stainless steel it is made out of?
304 is very common.
321 is available but very expensive.
The problem with SS is that it has high rates of expansion when heat cycled.
I noticed the pipes are welded 100% around from the outside; Corky Bell "Maximum Boost" recommends 100% welding on the inside and partial welding on the outside.
Due to the thin pipe walls and the thick flanges, 304 tends to crack like a **** - guess that's what the lifetime guarantee is for?

It doesn't look like the design is made for a divided T4 flange.

The price is pretty hefty given all the SSAutoCrap stuff selling for right around $100 on Ebay...

If it's 321, I retract all my statements - it's worth it for $500.
