the one thing ive noticed having both an n/a mk1 and n/a mk2 is that the 3s-ge has much more torque low down(obviously) and it definitely has more pull right through the range compared to the 4a-ge which is a lot more "peaky" power wise.
just reading through this, i didnt realise that a beams n/a could go into the aw chassis!
im putting one into my SW and i am so stoked to think that i could have an AW and and SW with beams motors
:O
that would be a great base for comparing chassis and suspension systems in each car
