bolt on .55 hx40 exducer & inducer specs

[Bmxr152]

Im looking for exducer and inducer specs for a bep .55ar hx40 turbine housing. I replaced my bolt on housing with an hx35 t3 .70 and machined out the housing but forgot what size it was. Now the turbo needs a rebuild and i want to order the turbine wheel before i take it apart. i dont remeber if it was the 64/76 or 67/76

Anyways if anyone has one laying around they could mic for me that would be awsome.

I'm pretty sure it is a 64/76

I'd measure it for you, but then need to unbolt my turbo.

yeah that's what im 90% sure that it is. im waiting for bullseye to get back to me.

76/64

okay thanks that's what I figured. Now I have a 12 blade now if I was to put a 10 blade would I gain a little spool?

Most that you'll get your hands on are 76/64; the 76/67 turbines are quite rare...but keep in mind that's the wheel spec- the housing must be slightly larger for adequate clearance.

A 10-blade turbine is better for flow, not spool.

The 10 blade turbine with the 60mm comp is considered the "super40" the 12 blade and 60mm i guess isnt but it spools decent.

The 10 blade turbine with the 60mm comp is considered the "super40"

Ask 10 different people what defines a "Super 40" and you'll get 10 different answers. I refer to them by their wheel spec and blade count just to keep things simple.
