My block needs reboring before I can build my new engine, and i'm gonna need to fork out for O/S pistons that are goona cost me around the £70 mark each. Now for about £80 I can pick up a fairly low mileage 1800 zetec bottom end.

So my option are:
1. Buy the O/S pistons and stay 1.6 (ish)
2. Buy the Zetec bottom end, skim the pistons and build a ZVH
3. Source an unworn cvh bottom end.
4. Any other suggestions?

I'm building the engine to run around 250 with a stg 3 T3, 500 sized intercooler, greens and L8, its not gonna be a garage ornament and used most days, so driveability is a must.
I've already forked out on headwork (mild porting and a piper cvhbp285t2 cam) and the head itself is good, so i'm not going full ZT (yet)

All suggestions / advise welcomed
