for the last month but have not found the manifold I am looking for.

try the parts trader.

I love the one in the picture from GURU.  It will be more likely to

try

to give them a call.

Thanks for the help.

Hi all,  I am in need of a cast iron HKS exhaust manifold to

complete my

TO4
installation.  I need the internal waste-gate type, but HKS

is

out of

stock
and does not plan any runs in the near future.  Does anyone

have one they

are willing to sell?  Ernesto?  Don't you have one sitting

around?

Sorry none for sale.  I have two HKS manifolds: One with a race

gate and the

other has no provision for a waste gate.  I'm going to use the

one without a

gate.  Try searching ebay or "The Parts Trader" on the web for

a manifold.

Another way is to make one out of  a RB flange, TO-4 flange and

some square

tubing.  I mocked one up and came up with a very compact design.

Also Dave I saw this Aussie T04 manifold at Seven Stock by Guru

racing.

First pic.

Second & third pics are local Rotech Nelson Wang TO4 tube

manifolds.

Jap Performance in Sydney also has a nice custom cast iron TO4

manifold.

Saw it when I was over there.

Probably it is old news, but just to make sure:

Check this 13B: http://personal.riverusers.com/~yawpower/ac13bt.html

Some things may be outdated, but others I never heard of on ACRE, like

oil

passage modifications.......

Paul Yaw is an ex-pat Acre contributor and very knowledgeable chap.

The oil passage enhancements he speaks of is because sadly the rotary oil
passages are not terribly great as they are merely shot drilled with 90
degree sharp corners (causes drag) these can be modified and are generally
modified for racing, the increased oil pressure is also done for racing and
is an easy mod. There are other enhancements like oil pump etc.

The water passages could be drilled out in the rotor housings allowing
greater flow but he doesn't elaborate on his mods.
