Default Need help w/ build motor?

what size turbo should I go with? Im trying to keep all parts matching to pull in the same rpm power band of 1500-6500rpm, I want the turbo to spool up by like 2000rpm if possible? how low of a rpm can you get it to start making boost? then pull right to 6500rpm. what turbo would support a 351. also what size injectors to support 10# of boost. 42lbs?what size maf to go with 80mm maf?, and what size exhaust? 3in big enough?
351w block all forged internals,blocks supports, girdles, forged pistons, 9.1 compression, H-beam rods.
AFR 185's competion ported, and shop ported 5 anlge valve and complete flow job, intake manifold, heads exhaust.
turbo cam operation range 1500- 6500 can a 351 motor pull to 6500, is this a good setup? help me out, could this be better? should I rev it highers? should I stroke it to a 393?...see im trying to keep it reliable and run good and see some life mabye 100,000 be fore it needs a rebuild, Im shooting for a 10 sec car or solid 11's.
Trick flow track heat 1500-6500
75mm tb
80mm maf ??
42lbs injs ??
size turbo?
3in exhaust
Is this all possible is this realistic, what kind of Hp will I expect to run, Im also prolly going to have to go with a stong blocks like a sportsman block or dart block

Yes its all very realistic if you have the cash. For one, if you want a turbo that is going to spool up real quick you are going to want to go with a smaller turbo. In my opinion a 60mm-66mm would work well. You could expect 500hp out of that setup fairly easy.

Also, your best bet would be to invest into a turbo KIT which usually comes with fuel pumps, AFPR, boost controllers, maj, injectors, headers, etc.

I know, im going with a kit, but thats what im trying to do is match up the kit or fid the right size kit?...Im not rally concerned about the turbo spool up at that low of a rpm, I would rather have more hp up to than to have the down low power..im sure the 351 h/c/i will cove the bottem end as much as the gears will cover the bottom end... so that area is covered, now on the to pend is where i need help. is 6500 too much rev for a 351, is the cam is designed and the heads flow to 6500, and intake 6500, and the springs are upgraded, it think it would, im kinda shooting for high 500 hp to the wheels, 600 fly, rember im going to be using a strong block to hanlde the hp.

There are lots of people here who could answer your questions but if I were you I would call someone up and talk to them. Call up the company that you are looking to get the kit from etc. and see what they have to say.
