this is fairly simple to do ..

wrt the exhaust manifold , you can custom make one with three branches out of the head onto a common log with one mandrel bend bringing the turbo over the clutch housing. this eliminates the need to cut the firewall to clear the turbo.

also , you can get two mandrel bends and use the stock exhaust manifold with a U bend welded to the flange , and an elbow to direct the flow back to another pipe with the flange this too will take the turbo over the clutch

mounting brackets can be made to the turbo from the clutch cover & right side engine steady.

turbo oil feed can be used from the line between the filter and the block
return can be drilled and tapped into the gearbox

the carb for the turbo metros are sealed so a normal 1 &3/4 carb will leak thru the throttle bushes when under boost...... depending on how much boost you plan to run , you might get away with a stocker.

a small intercooler may be mounted close the turbo and up over the oil filter and slanted towards te tappet cover to allow bonnet clearance

what about a pull through setup with the turbo behind the carb?

suck through has its benefits in terms of positive metering of the fuel as it will directly fuse under the boost pressure . mounting will be easy but the only hold back is piping an accurately designed manifold for the the intake , one that is too long will cause intake reversion . one that is too short , will cause surge of the boost .

The block was sent to the machine shop for some work I�m going with 0.030� oversize bore
I�m still in the dark with respect to the design of the air box.
