Camshafts: Suggest either 88+turb 252dur equal lobe Intake cam and using the normal exhaust cam (not the 2.3L) w/ adj cam gears. The idea is to delay the intake cam from closing so the compression ratio is reduced farther from slight reversion. After 40deg from ABDC, the compression ratio will reduce w/ late In valve closing. Another alternative might be the swedish dynamic Intake cam. Normal stock overlap should be fine for the setup. Basis being b/c the pressure ratio is close to 1:1 for 2.0L w/ 9:1 using T3, guess what the pressure ratio would be for a 2.1 or 2.0L w/ 10:1 using a T25. You will end up w/ more exh manifold press than intake press so less overlap is needed. Duration is chosen on basis of how high you want to rev and where you want the horses.
Another idea that has recently come to my attention is to extremely retard the intake timing to lower the effective compression ration w/o cylinder head modification, similar to the
miller engine concept. With a 2/70 intake cam, theoretically would allow room for 14psi of boost! I'm still researching the idea and will give it a try sometime down the line
