NItrous, yum. Ive got N20 on my MK1 XR2. The engine is in pricipal neigh on 50 yrs old.
This jsut prooves that N20 doesnt blow up engines, poor setting up blows them up.
As long as your engine is in good nic and there are no pre-existing damage to the rods mostly then you cna use N20 with no probs. 50bhp is all you really need. anymore and youll be draining your bottle so fast.
Talking of it, i might actually slap it on my valver too!
