I love people who say the CA is so old. Aside from the ECU's and the different materials making the block, what is old about it? The onboard sensors are nearly identical (in fact, you can use an SR ecu on a CA and vice versa through the use of an adapter harness or some tedious wiring). Let's see, the crank is forged with a main cap girdle. The rods are shot-peened from the factory. Oil squirters under the pistons- CHECK. It is argued the CA has one of the best head designs ever to leave the Nissan think-tank. Reason why it was replaced by the SR? Nissan needed a cheaper alternative. The CA was just too costly to produce.
And newer isn't always better. I can get all the equipment I need to tune my own EPROM for under $250. The old "Atari" 8-bit technology is good for something, right? Ever wonder why they still use pushrods in a lot of V8's even though a DOHC motor is more "modern"? ....because it works. (That and it saves a SHITLOAD of space under the hood
)
And to the thread starter, Ray @ Enjuku Racing here in Orlando had a CA18 in his S14. He was running a T60-1 and an SDS EMS in it as well. I would contact him if you have any S14 install specific questions.
And for those still calling it old, the CA was manufactured until 1994. Europe did not get the SR until the S14 model came out. EVERY S13 in Europe had the CA.
