Ok So... Im picking up a lower mileage engine for my SR in a few weeks and swapping it out as my rings are shot in my current engine. (I badly want boost but really cant afford it) So after chatting to one of the lads at work on what to do with my current engine, i was just gonna strip it down to teach myself abit more about engines and how they come apart and go back together, we have decided to try and build some sort of higher compression n/a engine. Obviously not being a mechanic(were panel beaters) were not sure what is capable of the engine, first thing thats come to mind is the N/A block with a glanza head. Either way im going to have an engine that is going to be rebuilt and my intentions are higher revving, higher compression. What sorta shopping list should i go for? Not looking for silly power gains just wanna have something to say i built myself that can at least laugh in the face of zetec s' and alike.
