Quick one - engine EK convo

[quang]

Hi everyone,
just a quick couple of q's,
Pretty much the least hassle and easiest engine upgrade for a ek4 is to a b18cr correct?
as in, don't have to get it engineered and redone at the pits etc. and its a straight drop in right?
A b20 while allowing to get better gains, will require engineering won't it?
However, a b20 has better driveability doesn't it?

Just looking at future planning :)

Thanks
Quang

you would have to get the engine registered with the car and thats about it. Dont you guys have a 15% displacement on engine conversions?
if u do then you wont need to get it done at the pits.

b20 on the other hand, you have to get it engineered.
