Hi guys today i bought this honda Civic 1.6 d16a3 120hp. Some info about it

D16A3
Compression : 9.5:1
Power: 88 kW (120 PS; 118 hp) at 5,600 rpm
Torque: 140 Nm (14.3 kgm, 103 lbft) at 4,800 rpm
Valvetrain: DOHC 16-valve, four valves per cylinder
Fuel Control: OBD-0 MPFI

My plan is to fit turbo, this what i'm wondering should i drop the comp ratio to be safe.
The turbo what i'm thinking to use is Garrett T4 it's a bit big but will see on the end.

I think theres a member on here just starting to do a civic turbo conversion i think you can buy a deck to put cylinder head on to drop compression i mite be talking crap

Yeah i'm thinking to put decomp plate to drop the comp ratio.

I'm thinkin to push it no more than 1 bar with the T4 with 8;1 comp ratio.
