Which turbo to go with

[cyclegrip]

So the whipples sold and I'm going single turbo with my cobra

Just wondering the key difference between these turbos besides price

It will be around 23 psi and t4 foot with dual 39mm wastegates

pt7675 billet wheel I can get from a friend that has low miles and not beat for $1200

bw s475 with billet wheel can be had for ~$1k brand new

gt4202 can find for around $1400 brand new

The next question is just get an anti surge cover or a race cover?

Id go with s475 billett wheel.
Best price and most robust turbos hands down

7675 can make a lot of power.
I made 800rwhp on pump and 1000rwhp on race gas with one a few years ago.

Those are all good choices. Why two wastegates?

One for each side of the y, wouldn't it be like the same as a twinscroll?

I would do two wastegates I couldn't control boost on my 76 with just one 38mm.

I have a single precision cea7675 turbo and I made over 750 rwhp @ 16 psi of boost and over 1000 rwhp on 25 psi with a 323ci motor. 9.0 to 1 compression.

Thread hijack. If one gets the precision 7675 billet wheel turbo, it the ball bearing option necessary? I thought I heard somewhere that it is not.

I am considering upgrading my ball bearing turbonetics 7668 this winter, but want to make sure I am actually upgrading...

I actually may end up going with a bw 480
