this was the plan for the pulley for the charger but with some calculations it turns out it wil run 19 psi of boost and 

that wil not last. i found this on a forum

and this is a 80 mm pulley  with a final ratio of 10 psi, a lot better.

so i let something like that made by a friend with machining skills

the original breather on the back of the engine is in the in way of the supercharger belt.

so i modified it, so it wil fit to the other side.

the rest of the engine wil be painted too.

the yellow is a bit to yellow by my opinion but i wil leave it like that

 

im now waiting for the crank pulley and then the engine can be back in the car

the supercharger pulley was too close to the clutch cylinder

so i searched for a aftermarked cylinder that is smaller and do the job right

Think you saved yourself a lot of heart ache getting the manifold remade. Bet the first first one leaked a little.

Looking good

yes it leaked a lot, next thing on the to do list is

 

copper pipe around the intake so the intake won't get to cold

it runs al ready on a hiff44 carb needle bdd turbo needle

but it's not running perfect, i think because of the carb gets to cold 

so after i have fixed that problem (copper pipe around the intake pipe on the coolant circulation)

it will run a lot better i hope

Nice Build!!! 

any specifications on the engine? Standard pistons? - where did you get the decompression plate? 

 

I am looking into a turbocharging a 998A+ draw through (or suck through) turbocharger

I'd ditch that idea if I were you and put a small weber on instead. The old wrapping the long inlet pipe with small bore copper isn't really addressing the problem
