6 cylinder jap engine: RB26 or 2JZ for my CAPRI? Edit: BMW M50 turbo? Hi guys. So i currently have a CAPRI powered by a cosworth YB engine that shat itself a month and I'm not keen on rebuilding it as they aren't the most reliable of things. I don't really Know much about 6 cylinder jap engines, but I've Been looking at either the RB26 or 2JZ Engines as a alternative. So my questions are as follows: 1. Which is more reliable? (If at all) 2. Parts availability? 3. Tuning potential? I'm looking for 450hp single turbo 4. Gearbox options. Not too fussed about running standard boxes and would rather use a conversion that uses a BMW diesel gearbox or similar. 5. Ecu tuning? Aftermarket or factory Anything else I need to know? bearing in mind my YB is gunna cost me approx 5k to rebuild properly. Thanks in advance.
