           We ought to fix your intake manifold while
           you are at it. I might have some usable parts.

       Well, It sure could use some refinements...  but you know how it
   goes,
       fix one thing and 10 more issues pop up.

       I like this term  "We" ought to fix it.  Tell you what.  If you make
       it,
       AND IT FITS, and dosent make my performance worse, I will pay
   you for
       it  :-)

       Someday after I retire maybe I will make all the improvements
   and sell
       FWF kits....  eh, but don't hold your breath  :-)

       I changed my mind about the motor mount. We will wait and
       see if you need a complete TO4 turbo charger and not just
       TO4 guts in the stock housing (which sounds like the very best
       turbo compromise BTW) :)

       Who and where are BNR Turbo?

       However I got all the parts for the intake if you want to
       borrow them. Then if it works you can pay me $1000 :)

       BTW are you using only two GM injectors?

   He he, nice try.  Parts not good enough.  I need the complete ready to
   bolt on finished deal....  or the old ugly one stays.

   I also have two stock injectors in the stock position on the center
   housing.

   Well what I have only requires minor work. The tubes
   are welded to the manifold and the plenum is built. Just needs
   ends welded on for a stock TB. It also needs some rubber tubing
   and clamps connecting the injector holders and the manifold part.
   You should be able to handle that :)

Well, "minor work" is one thing, but here are the problems:
1)cowl clearance on the top is about 1/4" in some places.  Will yours fit?
2)the stock turbo NEEDS the close fitting stock intake manifold.  There
is no way yours would fit, I would have to re-do the exhaust manifold
custom, new turbo placement becomes a problem.  That would probably
interfere with the radiator placement.  then figure out some way to get
the air from the new turbo placement to the intercooler.
3) alternator clearance is less than 1/4 inch
4) Fuel rail clearance is less than 1/8 inch
5) the throttle cable is fit to my my manifold
6) the fuel lines and expensive AN fittings are designed around my manifold.
7) the oil line clearance to the cooler is less than 1" clearance
8) the routing of the air from the intercooler has no clearance at all.
9) All sensors, injector wiring, turbo coolant lines, turbo oil lines
and PSRU oil lines would have to be re done if I changed the intake.
If I change the intake manifold, I would have to change virtually
EVERYTHING under the cowl...  That would all well more than a year worth
of work for me and a few thousand dollars, IF it can be done at all.

There is just no way to change something like that in a meaningful way.
Changing out the radiator alone is taking me almost a year.

Given that I am already faster than any stock O-360 lycoming powered
RV-6 (the biggest engine intended for the RV-6), and will soon be faster
than any 200 h.p. lyc powered RV....  I cant see that it is worth the
effort...

I could have done it better with a machine shop and a team of
people....  but that not really the point of it all.  Something fun
about having done it with a hand drill and a hack saw.

But thanks for your kind offer  :-)

Yes and the aero drag is not even optimized yet :)

I think maybe your fuel burn would be a bit less.
Same boost with less HP and back pressure out of the turbine.
Does sounds  like a whole raft of problems however.
Well the best thing I guess is to get it to cool better so you
can go faster. But you already knew that. Always time to refine
things later. You are still a young man.

BTW have you decided on a smiley or a hole cowl?
I was thinking you could add foam on the bottom of
the cowl, carve it to shape and make a paper mache female mold
for the add on scoop. Anybody that knows about play dough
ought to know about paper mache. Start saving those old
newspapers and paper towel card board rollers :)
