The 16v head should fit but i'm not sure if the cambelt tensioner system is the same. Manifolds would be completely different so a custom exhaust manifold would be needed for the turbo. You would be better off turboing the XSi engine fitted with maybe low compresion pistons and a turbo kit from DP Engineering.
If you stick to the 8v engine you have a few options and the bottom end is supposedly good for 300bhp but you need a new exhaust manifold to take a bigger turbo, these are available from a company called 205 Parts and are a modified design on the old Turbo Technics manifold found in the 205.

Is it possible to fit a 16v head to this engine, Say from a 306 GTi-6 or XSI? Also with regards to the exhaust manifold is there room behind the engine to fit a less restrictive one? If so are there any tuning companies that make these or would it be a one-off thing to make?
WRT fitting a 16v head i would be possible but too expensive, I'd imagine the oil and water galleries would be in the wrong places for a start.Hi, thanks for the replies. The DP engineering kit looks interesting, if a bit expensive. Would i need to switch to low comp pistons or is it possible to run the turbo with the internals I have now. I'm not looking for massive amounts of power maybe 180-200hp would be what I was aiming for. I'm not sure of the static compression ratio of the XU10J4R engine. The haynes manual I have says the (typical) compression ratio of the 1998cc XU is 9.5:1.
DP Engineering do a decompression plate which is basicly a thick steel gasket, this would lower the compression enough if needed. But i'm not a fan of those.
For that power i wouldnt bother with the hassle of a turbo and stick the XU10J4RS out of the GTi-6 into it with a set of cams and a remap and you should see 180bhp+ depending on any other spec.
8v turbo can be coaxed upto 200bhp easily for little money though.
