I've been following the stories on your car for over a year and am impressed with your dedication to the B12 series. Though we took different paths to make our underdog Sentras lethal performers, we have goals that are similar. I will post the pictures of my girlfriend's B12 as soon as my friend with the S2000 set up the mpegs and pics and quite possibly he's done because I gave him the video tapes yesterday. Did you put the rear disc brakes on your vehicle? I agree with the SR being a more favorable engine to build upon and the aftermarket does reckognize it's potential. The CA18 is a misunderstood engine that appears to be very complex, but in reality it is very simple. I just like underdogs and am not afraid of the unknown. 5 years of trial and error with the CA series engines. CA16de good power, great gearbox, can propel the b12 to 140mph pretty easy, but not exactly the torque monster. CA18DE a bit stronger, power is a bit more robust, likes to be revved to 8500 rpm, but softer than an SR20 under 3000 rpm. Basically the same as the DET motors except for the top end and in this case I chose the CA18DET because I've tested it against SR20 powered 240's, 200sx's, classic SE-R's and the break-away power just keeps going after 4000rpm. However, the low-end torque is a concern with my girlfriend's car so I have some new cams that I'm waiting to install. BTW both cars have stand alone ecu's one with 550cc injectors and my own will sport 4-850cc injectors as I have a custom intake manifold, 70 something millimeter throttle body, custom header and host of other expensive go-fast gadgets to assist my goal of a 10 second CA18 powered 4-dr B12 sedan (with A/C).
