I currently have a JDM B16a1. I was wondering if i swaped out my b16 block and put a b18c or b18b block in and slapped my b16 head on will it work? Or will i have to change cpu, tranny, mounts etc. Please help.

Will work. Without a different ECU or at least some fuel tuning you may not run at peak power though.

what ecu should i get?

qtiger

Nothing will really be ideal. A Type R ecu would be the best choice, as you won't have the butterflies of a b18c, but if possible I would suggest a VAFC or Hondata using your currect ECU.

Should be around the same price, and will provide much better results assuming decent tuning.

thanks! One more question. Could i do the same swap with a B20 block?

qtiger

Yep. Would work exactly the same as swapping in a b18b. I would heavily suggest some programmable fuel control if you went with a 2.0 block, but you'd get bags of power.

Thanks alot man! I'd like to get a B20 if i can find one. I just hope i have enough engine bay room for a B20 and a turbo:blue:

B20 is a little taller than a b16, but not any larger in girth.
