I have a swap sitting in my garage, it's the ca18det from the nissan pulsar. I have a bell housing that will fit the ka trans, and all the wiring and whatnot. I am unsure how to pipe the intercooler if I have an over-the-top intake manifold? and what downpipe should I use? I still have a stock KA exhaust. I will be running the stock CA t25 turbo until of course I get the t28. Any ideas?
