have you heard anything about it?

If the shop can make it fit, jump all over it! The S20g is not going to make much more than 440hp on a good day, where the 50 mm inducer off a 50 trim will push upwards of 500+. Its a no brainer.

Hmm I'd be interested to see how this 50 trim wheel in the 20G housing goes. The S20G is the biggest turbo I can fit in my engine bay... If it can be upgraded with a 50 trim wheel and make more power, that'd be sweet.

This may be a bit of a n00b question, but it would stay internally wastegated right?

Yes...

i dont think the 50 trim compressor wheel will fit in the 20g housing because of the size...

a 50 trim has a 3" inlet and a 20g is 2.5 (maybe a lil smaller)

It wouldn't be much to port the compressor cover to 51 mm +.5mm/-.2mm. But those are ROUGH specs. Any machine shop familier with turbo work could do it. FBM, FnF, PTP, *AGP, and such.

*IMO best choice.

And while your at it. Get a fab shop to bend up an exhaust manifold for an external gate and equal length. That's where the power will be!

yeah they would machine the lip to make it fit, I'm going to take pictures of it when I pick it up friday

This is going to be good!

I would imagine it would be like sticking a 50 trim in a B housing instead of the E.

anyone tried porting the 16g or know what the specs are to port it?

well you will definetly be selling your maxxfab 3in o2 housing since the 20g is different. same thing with your agp wastegate.
