Ive had, 366bhp GTiR built by hiteq, R33 GTR, Evo 4, Escort cosworth 410bhp + and i'd have my GTiR back over all off them anyday.
I had just one gearbox break in 4 years ownership, and i did lots of runs at santapod. There the same as any old car things pack up, mainly depends if you got a goodun thats been looked after.
