I'll second that. If you're worried about cost and complexity, put an L20B four in there: easy to find, low cost and (relatively) easy to swap in.

mate in my view go a L20b there cheap as chips n there not hard to get some power out of.a set of webbers n a cam will set u flying.. there a cheap and fairly easy engine 2 put in.. the onlyt thing is they wel effect performace ( handling) a skwidge and its said that they r a bit tall.... if u go a ca u will have a weapon.. but its ve3ry had to put them in...... 13b's belong in mAZDAS n it would be hard with rego etc . have fun n goodluck

hey all.
the time has come for me to finish my car completely. i have a 76 ute, hot house green, VYSS interior etc etc. the car is complete except for the engine.the 1200 goes fine dont egt me wrong but im lacking that extra power thats needed! everyone is tellin me CA18DET or 13b which id love to have either! how much $$$ would i be lookin at 2 fit one of these? also im just thinking of working a A series engine so i can get power and not be forking out thousands because of a turbo.
If anyone copuld help me out with some information or if you know of any ppl i can speak too it would be greatly appreciated!
