the gsr engine is generally 500$ more than the lude. go with the b28c if you have a plenty of cash (especially if turbocharging-thatll double cost of engine). it keeps your car more drivable than dropping the massive h22 in. you wont have to worry bout power steering or possibly ac and other alternator run accessories.
of course, if it was me, id get the h22 and turbocharge it, forget all those silly luxuries
