It wont work well, just ask anyone whos fitted a turbo technics kit to a 16i.
If i were you id swap the block for a RST lump with the flat pistons (ie lower compression).
With the normal compression youl be lucky to get 150bhp, and any more than 7psi and your engine will go all melty melty.
A N/A rsi with cam and decent set up will hit 135bhp
Not to mention the poor head gasket and bolts, if your straping on a turbo the least you can do to give it a change is treat it to a group A head gasket and heavyduty bolts. And if your doing that you may as well go low compression whilst its all out.
Intresting use of the cosworth intercooler, looks like it fits in a treat tho.
Will also be intresting to see if it runs on a cossie Dump valve, Id have thought your want a RSt one on there for vacum reasons?
What sort of ECU are you going to use? I know of a few mappable ones up for grabs, which id advise you use to make adjustments as your doing it all bespoke!
