[quote=applesandoranges2010;4656757]Here's the reply from areasix about the 500bhp.
Yes I am able to supply a 500HP unit no problem. The engine alone is £4950, and that's rocker box*to sump, and an assurance it will exceed 500HP on an engine dyno (much more on a Rolling Road).

Be aware that you do need an appropriate Inlet manifold and turbo to achieve your goal. I will happily supply all parts inc ecu, injectors, loom, manifold, turbo wastegate, etc and you have the confidence that all parts will be reliable and appropriately specified.

Diff between Silver and black-top - Silver has hydraulic followers, black top is mechanical. The basic port shape on black-top's is a little better on the inlet port. The black-top has a second idler after the exhaust cam to 'wrap' the belt better around the exh cam pulley.
The main caps on a black-top are much shallower. Oil pump on silver-tops integrates the oil filter mounting. Water pump on Black-top sits forward of the block, silver top sits into block.

Silver is easy to mount into older chassis, black-top fit's easier into later models 2001 onwards, but can fit into earlies with custom mounts.
crazycage soz i just couldnt resist either lol!!
on a more serious note iam 4x4 a mk6 fiesta with a 500+zetec turbo using cosworth running gear so if you need any help let us know. the gearbox wont handle 500bhp and needs uprating with a bara straight cut gearbox which is around £4000. then front diff and rear diff expect around the £1000 mark each , drive shafts x4 £1000 , prop £250 then it all depends on what setup you want , cheap is using cossie floor pan , subframes, rear beam and make custom mounts, expensive custom built tunnel ,floors ,rear tubs for wide tyres, wrc rear independent rear end , etc etc the list goes on.
knowing paul johnson (179mph 500bhp+ fwd fiesta zetec turbo )it will be a handfull but paul really enjoys himself and hes just had a nice 80bhp increase lol
i would say keep it fwd unless you have serious cash and time on your hands waiting for work to be done because at this level you either have to be very good at welding or get some decent firm in
hope this helps
heres a link to my thread to show how much works involved and it aint even half way there yet!
