There's no difference between the 130/150 base engines, it's all ancilliaries. The 150 has different injectors/turbo/intercooler but is otherwise the same as the 130. The chassis has the sports suspension fitted as standard, but other than that they're very similar.
The 150 will easily produce a reliable 190bhp with a bit of tuning, some have had clutch issues with the torque but a 130 shouldn't have much difficulty.
Dan what's your budget?
