Turboing 1HZ with std manifold

Turboing 1HZ with std manifold in 1985 75 uterous.
Is there enough room to mount the turbo on the stb exhaust manifold with out placing it too close to the ground. What would be the recommended boost with out an intercooler. I plan to manufacture an adapter plate to mount the turbo to the std manifold.

Turbo glide here in wollongong do a transition piece for this sort of system...works ok...turbo is alot lower, i would be getting the manifolds heat treated with that ceramic coating to keep the exhaust flowing fast if you do this.

heat treating the manifold with the coating would help keep the exhaust gas hotter for longer? By using the std manifold I will keep the cost down as most other items needed can be easily manifactured. The reason I am following this method is because A company in brisbane uses this method as well. Mike Vine Turbos. Any other recommendations?

The main reason they make the shortest possible rout to the turbo is because the gas cools quickly, and velocity slows down, which you need to spool up.....now we arnt talking racing application here, and it would probably be cheaper to buy a turbo manifold than take the std off and coat it, so i would probably live with a small difference to a highmount....

is there anywhere I can sneak a peek at one of these transition pieces?

What about using the front half of a 1HDT manifold? I was told these cost about US$150 in Japan.

the only downside I see with it is that you have to use a turbo with the bolt pattern of the manifold, which probably limits you to a toyota turbo.

They are only a double flange with a small piece of steam pipe between them to bring the turbo pattern flange horizontal, and then the turbo bolts off the std manifold....compressor forward, exhaust turbine exit at the back as per usual...

I actually saw a kit that uses the standard maifold with a turbo, pm me
and i will let you know of availabilty if either the adapter is available or just the kit.

Cheers
