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Some things may be outdated, but others I never heard of on ACRE,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

Okay!
Probably that's where I got the link! :)) .....as it doesn't show up
anymore on Paul Yaw's new site.
I read his articles about porting, interesting, especially the need for a
flowbench!
Did ACRE ever discuss mods to the oil system? If so, it must have been
before I joined or I just missed it.
If anyone saves the posts, would you be so kind to forward them to me?

Yes we did but the racers are running at 10,000 and 11,000 RPM so
it is not that important for our use. There is evidence that
the oil temp can be lowered by 10 degrees or so by coming straight out
of the oil pump.
