Is that for a redtop? The 16v engine or the 8v 2.0? Or the ecotec?
I've a 2.0 8v [20seh i think] in mine atm.. looking a new car though
And haha that's cool about the bushmills xD
I always say i hate Ireland but i secretly love it. It is a really beautiful place if you know where to go. Example, where i live is full of scum bags and vandalism/theives/broken glass everywhere and like every other night they light a fire with all junk, usually someones garbage bin. But then again, go up near Donegal etc and its amazing. Guess you get this to an extent everwhere.
Anyway back to the point. The retop engines are notorious for the head's going porous as their aluminium. Coscast is a better version of the head and can be identified 2 ways, It has a sortof.. Z shape on the side of the head that the GM aluminium head doesnt, or, under the exhaust or intake [cant remember] there's a coscast stamp. Idealy you woul want a coscast head if you're buying a redtop.
The 2.0 8v engines, c20ne and the 20seh are bullit proof. Really are. So reliable, and not that hard on the juice if maintained properly. Parts are cheap as hell too.
The ecotecs, i honestly don't like. They're a watered down version of the older opel engines. the 'C' labeled engines and before. exmaple, x20xe is the ectoec equivilant of the c20xe. Sample compression ratio, same displacement, bore etcetc, but the head and the ports are different. They're a more economical version, and thus they don't show the same benefits a redtop would with mods. Think the 2.0 16v ecotec, x20xe is around 130bhp? Can't remember offhand and the redtop, c20xe, is around 150bhp.
Choice is yours, redtops are few and far between these days.
