Gts-r manifold like I've never seen.

[LaurelPWR]

Can anyone identify what the go is with this manifold? I've seen many rb20det-r/Gts-r manifolds and I know what they are but I've never seen one like this...The owner claims it's an Autech rb20

I was meant to be buying it from him but after seeing photos I've been put off..... Very strange looking manifold..

[LaurelPWR]

This is what I expected to see....

Why wouldn't it be an Autech made manifold?  It's certainly not the Nissan one like your second post.  The collectors for that manifold are quite difficult to fabricate, being made out of 2 halves stamped out in a press.  The "Autech" one almost looks as if it is made the same way, but with the 3 runner arranged on a curve instead of a straight line like the Nissan one.

 

FWIW, no amount of my google-fu could turn up another image of an Autech RB20 manifold.

Even the bolts that hold the cover to the exhaust manifold are different to mine. Looks like someone has tried to copy it? Not sure but doesn't look like mine at all with the cover off.

I know I have seen some Autech manifolds but I cannot remember what they look like.

You wanna sell yours? [emoji12]

Nah. Took me a year and a half to find a manifold, then another six months for a cover.

You wouldn't believe how many people want to buy it off me haha.

Yeah Autech GTS-R manifold. There was a good picture comparing R31House vs. Autech vs. standard GTS-R manifolds but can't find it any more.

From memory, Autech has slightly shorter runners, or at least differently shaped.

Are these things even TS?

Never looked into them.

The proper (Nissan) GTS-R one is twin scroll.

Add me to the list.

 

I'd need a r31 to put it into but that's the easy part.

Awesome thanks for that man! They don't appear to be anywhere near as good as the Gts-r manifold.... They don't look tuned length or a decent merge

I'm fairly certain the Autech mani is T2 flange, so be warned. The exhaust housing that comes in the autechs have the 5 bolt rear.

Yes but the turbos are not

 

lol

well that's kinda nearly pointless... however there's still form of scavenging effect nevertheless..

[niZmO_Man]

Hey man it was made in the mid 80's.

Also, found this, R31House top, Autech bottom:

[LaurelPWR]

The autech manifold appears to have the same flange as the r31 house in that pic and not a t25 flange as someone said earlier in the thread...

Just out of curiosity, would anyone be chasing an autech manifold?

AND

What would people be willing to pay for one??

[LaurelPWR]

Well if anyone wants an autech manifold I have access to one for $300US plus shipping through a guy who has the rb20 autech motor...
