Thats a HUGE exhaust side lol. If you already have the turbo then try it out. If you dont like it then sell it and get something else.

Be a pretty decent drag setup but laggy on the street.

Yea all BW stuff is 5". I think Atomic nailed it. If it's a dedicated drag setup then you can can make it work with a T-brake, 2 step, gearing, converter and some good tuning. If you want to enjoy it on the street, look for a 96 wheel and housing.

Use a sound performance spool valve if it is too laggy. I will be using a 82mm borg warner with a 88/96mm exh. wheel and a 1.32 a/r housing on my 402 that will be around the same compression ratio.

Depending on the specs of the camshaft and who does the converter, it shouldnt be laggy at all.

Its difficult to understand the description you gave. Is the turbine wheel 126mm inducer?

You will really be able to drive the exhaust side with that turbo. Id be putting a tick more compression in it. And a cam thats about 235/243@ .050. Id be targeting an rpm range of 4000-7000 with the setup.

Will be a real nice 1300-1400 horsepower capable combination if you set it up right.

My buddy had a s480 with the same 1.32 and 96mm on his 383 and same cam with the pro flo and 6sp. in 3rd gear at 2100 rpm it would make 1 psi and full 15psi at 2900. It was not laggy at all. Has 3.25 rear gear.
