nah mate not drugs common sense this is a very good and very popular swap
some reasons for the swap
1 no need for a custom plenum.
2 power fc bolts straight in
3 there are heaps of parts for them.
4. it makes the weight distribution 50/50.
5 there are no high profile ones and i like to be different.
6 I found some one who is willing to do the conversion for a reasonable fee.
7 the motors are more torquey.
8 the gearbox just had 2k spent on it in a full rebuild
9 the motor only has 80 000 genuine klms10 when I need to upgrade things like pistons and injectors I will only require 4 not six
and development on the rb20 is finished in japan
