thomas,you're one english channel width away from a country that can supply anything you need.try the demon tweeks website,they will have bellhousings there somewhere,& can probably put you in touch with the manufacturers.or try someone local.there must be a motor racing association you can call for some advice.basically,dellows is just a mob doing castings,& any price advantage would be swallowed in freight.use the ford box,because i'm sure there'll be more of them kicking around than the toyota box.plus they used them behind sierra's,so they'll probably have some aftermarket parts.the web site for demon tweeks is www.demon-tweeks.co.uk.please don't think i'm being rude or such.& good luck with the search.that little toy will be a monster with the ca18,even at stock boost.paul.
