I'm putting together a 20b pp turbo motor. Looking on some advice on what exhaust housing size to run om my gt45r turbo?
I was thinking of running the 1.28 hot sode . The motor will see 10k rmp range.

Do you guys think 1.28 will be good or bigger will be better?

Thanks

 

Are you serious? Its a few hours early for April fools.

 

that is pretty rediculous dude

 

Nope no April fools.

 

The exhaust side will have to be very large. Larger than 1.28

 

They normally come with T4 turbine inlets. . .be sure to go T6 on this. That said, I agree with Gto as well.

 

Thanks. The biggest t6 housing i can get for the t45r is 1.15.
So t4 1.44 will have to do i guess.
Or i will go with a 1.15 housing a big 60mm waste gate and run 3 runners to the waste-gate. Will be very responsive to relieving pressure.

Let me know how this idea might work?

 

Why not use a street port? Are you building a track car? A P-Port obviously gives you more top end, but you're not going to be able to put it to the ground with street tires and there are a bunch of trade offs. Why sacrifice low/mid range torque for another 50-100hp when a well sorted street port setup is already traction limited?

My 2 cents . . .

 

A good size for any peripheral port engine would be 1.5"

 

Thanks or the info. I went with 1.44 the biggest what is offered for my turbo.
