Turbo in a 12A carb.

I'm looking at turbo charging my 12a with either a draw thru or Blow thru sys. which is best..I don't want to buy an expensive turbo kit..I have a garage full of turbos and intercooler etc....I'm good with a welder and torches and customized many vehicules if anybody has one of these setups post me some pics..I sort of have a plan and an idea how to build it,,I'm planning to use a small IHI turbo from one of my Mx6GT,stock boost is 8.7psi,is this too much and looking for a reliable setup with nothing too crazy..I know I could swap for 13Bturbo or go for the Japan 12turbo but I want a custom setup with carbs. cause I won't have to screw around with the Ecu..So any ideas or pics please post.I want to start soon..

Do NOT do a draw thru setup, blow thru is MUCH better, and easier. Something about bringing the fuel/air mixture through a hot turbo just doesn't sound too good

I just searched to find the basic list of things you need to do that I have posted before. You can use other parts, but this is the cheapest way I know of to do it.

-TurboII Exhaust manifold - oval bolt holes, grind exhaust paths inward so they match the 12a manifold gasket
-TurboII Turbo
-TurboII Wastegate
-Nikki(stock) Carb w/mods done to handle boost
-12aTurbo(j-spec) intake manifold(stock will hit turbo)
-Turbo Hat for Carb
-GSL-SE Fuel pump
-Rising rate Fuel pressure regulator
-New fuel lines
-Drill hole/put in fitting in engine front cover for turbo oil return line
-T fitting where the oil pressure gauge gets it's reading from for turbo oil feed line
-Remove vacume advance and weld centrifugal advance on distributor.
-Downpipe + whatever you want to do with the rest of the exhaust.

i'm sure the pure removal of all emissions related pieces, using special gaskets (forget what they're called) that won't bleed out under boost, some jb weld , and mechanical secondaries. I THINK, i want to get mine setup for this as well.
