looking to put a turbo in it one of my mates just put a ca18 in his dato 1200 coup im thinking of similar please give me some recomendations thanks

the easiest conversion to do on an old model bluebird is either an SR20DET, CA18DET or FJ20ET.
www.910bluebird.com has a step-by-step article on both CA18 and SR20 conversions

you can get a turbo ca18 single cam rwd. they are a bit hard to find but they are simple and easy to work on. boul all the turbo gears onto a ca20 trx and you will be away. Standard boost will be all the ca20 could handle though.
