OK here we go. For the last month I've had my SiR I (LSD) on order from HMO, and I got to thinkin' maybe I should just put a C5 in there. I mean the cost of the C5 will probably be more although for the JRSC I have to buy BTC ect.. On the other hand the B18 will be N/A and will be less likely to break down?? What do you people think will be the better choice? (BTW this is probably gonna be the most I will put into the car--I dont have the money for FI on the C5) Please help from the people that have seen the differences in these setups!
