Hey,
yeah a 5.0 or 5.5 motor will be suitable, but it won't have the rip and top end that you might want.
At btcc mendip last week I ran a 4.0 and probably felt it could do with a few more ponies.
Gearing wise. On a 4.0 I was on 8.2, a 4.5 i'd say about 7.8, so with a 5.5 yourll be looking in the high 6's for start ratio for mendip (assuming your on LRP/Nosram esc..)
