yeah good point... im sure meggala would be able to answer that as he got ICE to do his... he may have got a good rate on it... i do know he didnt do 80% of the work.
the upside to using an SR20 is it gives the car a better weight distribution... is lighter... u only have to pay for 4 injectors, 4 pistons etc etc if you wanna upgrade and parts are more readily available and cheaper than they are for the RB20
