i'm probably being a bit ott with the cautious approach here but i'm looking at building myself a new engine pushing around 250 - 300 bhp over winter/ next year so was just wondering if there's anything i need to be looking at uprating with regards to the chassis?

More like uprate your underwear!

yeah it's gonna be lively but i'm getting itchy to do something with the zetec i have sat in the garage needing a rebuild and i'm pretty convinced i can turbo it fairly cheaply. just bored with the pinto now even though there's nowt wrong with it i just want to play with things!

Some more triangulation around the engine mounts maybe, plus u might need to have some gun drilled driveshafts made and propshaft uprated.

I'd consider adding some triangulation in the upper engine bay. Firstly, a section over the gearbox between the curved footwells, then from ends of the new section forward to join the side rails where the V shaped triangulation meets inside the upper shock mount.

If you're going that far, then a prop catcher in the tunnel would make me feel safer too.
