I'm sorry,no need to feel bad. Lot's of things are possible and I've tried alot along the years but when giving advise to someone I would rather give advice that works 100% of the time than info that has much less chance of success. If this combo was for a 3000lb car I might suggest something different.For fuel I'd guess the poster would like not to be locked into buying 91(or better) octane fuel,but thats a guess on my part. Again no offence intended.
