Re: is jim mock motorsport as good as they say?
im with gm, if you can do the work yourself, DO IT. if you want to save $ and get what in my opinion is more grunt, DO IT YOURSELF... i mean, they dont do anymore than any head porting place, cam supplier, exhuast shop can supply... theres no magic involved
if you cant, possibly go jmm, if you want a drive in and drive away, go jmm. (or fit their bits yourself)
if you r prepared to come away with a bit less KW than their quoted figures, go jmm
if you want the service/support that they can supply, go jmm
