My goal is about 700whp... Do you think it's possible and reliable to my engine with the mods that I list this power?

I'm kind of new to the whole "turbo" world, but I bet most people are going to suggest something along the lines of a BW S300; bigger than 56mm. Twin 60's would be along the lines I'd be looking to do. A SBE 4.8 is pretty damn stout, and with the right tune, will handle 700+ rwhp reliably.

700hp, I'd go twin s200 chassis. 59s at MOST, if you must stay twins. Those could support 1000+ hp. t3 .70 a/r. would be a badass combo.
For 700hp though, lots of people will tell you to go single. Really boils down to fitment and personal preference, but 700hp is easily acheived either way.

S200 is the black. the other is a K27

AGP Turbo do some S200's with their own compressor and turbine housings which make them far smaller than the regular BW S200's
Really...for your power goals and engine size, anything in the 60mm range would be rather on the large side.

So, to 700whp, a 56mm compressor, 58mm turbine is fair enough?
I know that is relative, but how much boost do you think it's necessary to reach 700whp? About 1,0bar?
Anyway I will start with 0,5bar and put a booster.... because I will use the car on the streets too....

If you want faster spooling, I'd say go for those 51mm units. They will meet your power goals. On a 4.8 I'd still say the 56mm's would be on the larger side for your goals.
As for boost vs power...far too many variables to say.

Do you think that the T-56 gearbox handle 700whp/wtq ?
Thanks for all the help guys.
I will post when the project going on...
BTW, In the back I will use a Supra MK3 diff with a custom cradle, and 350z axles, and 240sx hubs.

Reading through many different threads suggest that you may get lucky with a the power using a stock transmission. It will depend a lot on your driving style but I wouldnt bank on the trans holding together too long. Remember, in these V8 motors your HP goal may be 700rwhp but your Tq will likely be at or above that number and thats what kills the trans.
Nice unique build I will be watching closely.

how much power and tq?
Have you ever seen the PPG Gearbox to T-56? (probably is too expensive I think...)

edit: forget about PPG... it's $5.000 +

Unless it's full on drag use, I would have no concerns whatsoever about the trans holding that sort of power.
