Well a 2.3-16 atleast in euro form has a major hurdel for turbo charging, a compression ratio of 10+ to 1. so i say go with a 3 layer steel gasket, to drop compression. keep boost to 0.48 bar and ur stock fuel distributor will cover u, worst case look for a 2.5-16 fuel distributor. Mind u this only a quick fix as ur consumption and AFR will be some what off on part thorottle runs. i suggest for best value yet economy try and do a setup like the one RBYCC has on his M103.

Edit: Just realized, haven't said if its 2.3 or 2.5, any way 2.5 is 9.7 to 1 while 2.3 is 10.5to 1. in any case find a way to drop either down to 9 or 9.2 to 1
