Whould I be able to use 2002 tii piustons on my 318i engine to achieve better compression for a turbo set-up? I would like to run about 10-15 psi.

I am in the process of the same project. Adding a turbo to my 85 318i. I am not however trying to run over 8 psi (yet). In the book "Maximum Boost" (Corky Bell) the things needed to be concidered are (based on running over 8 psi) fuel management, larger injectors, fuel pressure regulator, boost timing, aftercooler, and of course compression ratio.
The 2002tii engine is basically the same as my 85 1.8L. Stands to reason that the postons will work. I have also read somewhere that using the "e" head since the "e" motor ran lower compression also. I am using the stock head, stock cam, +.50mm pistons, std brgs, stock injectors (until deemed usless). I will be chipping away at this thing for preformance little by little.
Good luck, I hope this helps. Any questions I might be able to answer, email me.

I run 8.8:1 CR on my turbo, dont even start pulling the timing back till past 7psi of boost(regular pump gas), that being said I have major work done to my engine to maximize the detonation resistance.
Tii pistons are raised top, see link, and very cylinder head specific.

I am also interesed in this topic. on a 318i E21? E30? are you running the stock Fuel injection? what modifications have you made to the timing curves fuel curves? it is an m10 engine right?

I am doing this on a E30 318i. I am trying to stick with the stock fuel system but the more I look at it, the more I think I will need a piggy back system to increase fuel. I will be putting in a ford Turbo Coupe fuel pup to offset the lack of fuel. There is the possibility of using a rising rate FPR.
