Hey guys I was wanting to know what the big difference between the B18C1 vs. B18C5 I know the C5 is considered ITR, but they have the same Bore and Displacement, the compression seems to be 10.2:1 vs. the 10.0:1 on the C1, if I used a P73 ITR ECU and ITR Pistons in my C1 will I get the 195HP or close to it like a ITR C5, seem like it or am I wrong, and cant I use the ITR Pistons and Rods in my C1 since they are the same bore, please advise I can get them cheap and am considering upgrading it would be cheap for 25 more hp, thanks
