Ok so if I go out and get me a used engine to tear down and build up for power where can I get parts I know where to get things for big blocks and small blocks but this will be my first 4 banger motor that I will be building. I am open to any suggestions for different motors I was going to just get another 1.5 and build off of that.

 

You know this would take alot of work but it would be cool to put a (Nissan) sr20de or det in an xb.

 

Rods - Crower through Dezod.com

Pistons, Wiseco, custom order
http://www.importperformanceparts.net/
Look under Scion > Pistons > Custom pistons

Everything else - Importperformanceparts.net
http://www.importperformanceparts.net/
Look under Scion > Engine Kits

There is NOTHING currently available for our heads, no valves, no springs, no cams. Best bet is just port / polish and clean up the turbo manifold

 

After the engine gets built don't forget a 365 Turbo kit! ;)
