Hey guys so here's the plan I just bought a fc3s 13b na and want to swap in a different rotary engine the TII engines run $1000 and fd 13B-REW runs $1700 I'm looking for the easier swap and want only 1 turbo looking for numbers around 350-400rwhp any info on specs/pricing/ease or whatever would be very helpful thanks guys

 

The easier swap is the TII engine from the same series of your car. I you are getting an imported j-spec be prepared to rebuild it.

 

For 350-450HP, the easiest engine would be an S5 TII engine. They have the heavier rear plate like the REW but bolt right in. You're going to want to rebuild and street port it, if for no other reason then the condition of the engine is unknown and the street port will make achieving those power levels easier and lag free.

Of course, remember that you will want to put the whole TII drivetrain behind that engine.
