What's the IWG size on the 9280?

On a 20b, will it be able to keep boost around 12-14psi?

All B2 EFRs( 7670 on up) have a 42mm divorced WG in the direct path of flow.

I know of 2 9180 iwg 20bs and they both hold 10 psi to redline.

Have you had an 8374 on a 20b? Would it drop off like a 7670 on a 13b?

I'm only looking to run 15 or so psi. Wherever the power lands is where it lands. But I don't want it to feel like it gets sluggish after 6k rpm

Our 20B sees full boost before we can completely load it on the engine dyno with a 9180, I wouldn't want to even try an 8374.

Oh, that's with a 1.45 turbine housing.

Are the turbos in the group buy available with a black compressor housing? Saw it on the 7670/8374/9180 on another site and kind of fell in love.

8374 is way too small for a 20B.

Will an 8474 fit with a Xcessive LIM in place?

Sometimes yes( bolt in no mods) and sometimes it requires an 1/8" to be milled off the flange that meets the block( or you can grind on the front runner).

BW has let us start placing orders for turbos! This means BW is getting closer. Pricing for turbos only has been updated on our site...
