I have a 99 em1 with the b16 obviously and am going to switch over to a b18c block, what exactly will i need that I don't have right now such as new mounts or should this block drop right in?

 

Since you already have a B16a, and if you are just switching to a lager shortblock, you should not need to buy any parts, except for things you may want to refresh.

The newer B18C blocks have the newer style oil pump with crank sensor which can be reused, or you can take one from you old b16, or you can use a bypass mod all together.

You will need to swap the driver side post mount for the engine to mount properly.....excpet for the ecu, everything else is petty much plug and play

 

Alright cool, yeah i think I seized me engine so I am just planning on taking that out possibly rebuilding it but getting a b18c block n whatnot!

 

Fried my EM1 too, 14krpm . type r is in the works!
