I do not have a converter on my 87 all stock GN now. I do have the original prom and I will not be changing it because I want to keep my 87 GN more or less as close to original as possible. I can put the factory converter back on if I want to one day. Only take a few minutes. It only has 10,350 miles on it now. I've owned it for a year now but have never really spooled up the turbo much for fear of melting a piston top with detonation with today's not as good premium gas. So my idea is since I will probably only drive my GN at most 300-500 miles a summer (at best) is to keep mixing in some race fuel to bring up the octane so I can run it flat out occasionally and not worry about knock. This place shown above is fairly close to me. But look at all the race gas options! Which to use?? Maybe just that lowest cost leaded? Searching for higher octane fuel locally I find some saying that some higher octane gas just has some additives to raise the octane and is not really high quality high octane fuel. I want to think I should stay away from that type of higher octane fuel? I'm pretty sure all the race fuel sold at this Shell station is all high quality. They seem to be the biggest supplier in the Milwaukee area for race fuel. If I get the 110 octane I am thinking I can add maybe 2 1/2 gallons to each tank and that might be enough to insure I do not have any pre-detonation (knock) at the factory boost level?
Any opinions?
Thanks
