For a 5.3L T56 truck, looking for ~600hp but with good usable power in the mid-range, would you recommend the On3 T76 or the GT45? The GT45 has the bigger 77mm turbine side so it won't choke out as soon, but only a 68mm compressor. While the On3 unit has a small 65mm turbine but the larger 76mm compressor. I'm torn between these two!

Question I have a built 6.0 stroke stroke but warhawk heads and a vodoo 294 cam that's range from 2900 to 7400 and with my hi ram Holley I plan on taking it to 7400 do u think one of these in a single would push around 900 hp or do u think even if I when twins with the on3 would they choke out at that rpm range

I think you would be maxing it out before 6000 rpms with a stroker motor. Twins I think you will be fine.

I talked to on3 today and 3 to 4 months they're thinking theyll offer a 88 mm single so I think I'll wait and get that it should be plenty and hoping it won't run out of breath i asked him what the specs will be and he said hell have to get back to me on them

I think one of the other Chinese turbo makers (or Brazilian as the case may be) was about to release one as well.

yes i think magnum was supposed to have an 88 already or same story, getting one out eventually.

Can you buy the gt45, and then buy a t6 housing? What's the most ho you can make with the gt45?

I think 750ish through a 6spd on boost only will be maxed out. I may be severely wrong but we are trapping 143-146 on 10-13psi @2900 lbs. and still spinning some. This turbo will go in the 150s at my weight if we can put it down. I can imagine what 20psi would be like if it stayed attached to the ground.

Is there some place where there is some info about what materials to use when modifying a cover ? I tried to search for some tips but didn't find any thing.

Thanks GD

I fiberglass thin metal behind the hole, then use some " kitty hair" bondo for the front.

I have this smaller one thats smoothed out and filled in for sale
