Yeah as above.
GRS is widely regarded as the best on this forum. There are other options though, Airtec, pro alloy and others will be up to the job. You'll also need new slimline fan(s) which are expensive.

A Stage 2 T3 Turbo will give you good spool up and will be sound to well over 200bhp. at about 220 - 230 you'll want a Stage 3 T3. this will take slightly longer to spool but will have more legs.

With the turbo, intercooler and a setup i'd say you'll be safely around 200bhp.
