in my view theres no such thing as a budgeted 200bhp, if you want 200bhp you might aswell do it properly the first time.........

But if u want a stressed 200bhp on a standard bottom end and head etc, a grs, stage 2 turbo, 18psi+,cam, and a good setup, u might see 200bhp.... or might see a rod through your block.........

On the otherhand you can go for a bottom end rebuild with forged low comp pistons,arp bolts, (rods, if u can afford it), with all what was mentioned above and you will have less chance of detting, and damaging your engine, your car is a good one so keep it that way and do it properly and a 'safe' 200bhp with the choice of extracting more power in the future...

Hope this helps, thats what ive done with mine, and the outcome is worth it.
