You obviously dont know what youre talking about. Grand nationals came with 250hp and 350lbs/foot stock. Their engine comes turbocharged stock.

How much boost or how much HP? I run 22 pounds of boost all the time thanks to my SMC alky injection setup. No problems with that. As for HP...most of the guys I have with run mid 11's and then are all still on stock internals. I think you can run high boost all the time as long as you don't knock and thus nothing gets hurt.
fastazzhonda - the NA 231 Buick makes about 110, the turbo but non intercooled ones make 200 or so and the intercooled ones make from 250-275. Those are of course stock and kind of generalized. They sure are fun cars to modify. I added aftermarket exhaust, K&N intake and raised the boost and run low 12's on slicks......what a rush.

the main consern is pre deatonation. keep that out of your block and you be ok. i have a dyno sheet for my car that reads 453HP with what little mods i have and the only thing i have done to the engine is repace valvesprings. i run 12.68. 12.70's all day with street tires (just bought slicks yesterday can't wait
 )as for fastazzhonda  , i have yet to find a street honda that only has 1,000$ in it and isnt complety stripped to the bare bones that can hold a candle to me
