i have a white vn 91 lpg/unleded 5 speed manual 17s, what else can i do? help me please but im a p plater so i cant do turbo or anything like that)
cop chip, pulp, vl diff gears, mang it like you stole it..... search for buick v6 upgrades order one of these from the USA with a 4" bore and stroker crank and the rest of the engine parts to build it and then you'd have a fully sick v6 http://www.taperformance.com/proddetail.asp?prod=TA_V3800
in all seriousness, yes if it's tuned for it you can notice the difference, in both the v6 i have s1 vn, vr it is definitely noticeable and more sluggish on 91 ulp to 95/98 pulp. now yes i'll agree using 98+ ron in a vn-vp v6 is pointless due to the low cr, but 95 will make a difference in the earlier ones.
I guess I'll have to try 95 then. I was going to use 98, but if that extra isn't too noticeable I won't bother with the 98.
