I am trying to decide on which wastegated turbo for my 617 that will hopefully have one of Goran's 6mm M-pumps. I am running a higs stall converter and am looking for better low end and not worried about top speed. I am considering the MasterPower R442-2 as well as a Turbonetics T3 F1-49 50trim .48A/R in either a standard or ball bearing. I am not worried about price, just performance. I am leaning towards the ball bearing turbonetics but am open to all suggestions.

I fprice is no issue, a larger variable vane will get you what you want. Others can chime in on the exact model(s).

At this time I am only interested in wastegated turbos and price is an issue. I can get the turbonetics ball bearing for $850.00 new and the standard for $600.00 or the MonsterTurbo R442 for roughly the same price as the ball bearing turbonetics.

With a budget that high you should be able to get a used HE351VE, but be warned-it's a HUGE turbo

Forum member kmaser has said his 617 in his G-wagon with 6.5mm MW elements and the Master Turbo R444-2 is working awesome. He was looking for low end grunt and a good top end.

Yes huge turbo, probably not a good choice for low end power.

I am looking for more low end, not less.

Yes, I think I have read everything about the masterpower r444-2 on this forum site and am definitely considering it.

Since you want to stay with the wastegate turbos, another idea for low end grunt is compound setup.

Perhaps using a Mitsubishi (MHI) TD04 or TD05 type for the small turbo and then a HX35-40 for the upper range. The MHI turbos are plentiful and have different sizes within the types and are closely related to the Holset HX20-27 models, and of course you can get the HX35-40s anywhere.

Well I ended up buying the MasterPower. Thanks for your help.
