I have two turbo's that have no label plates and I am wanting compressor maps for them so I can choose the one that will suit my needs better but am not positive what maps I should be looking at. Can somebody with a big brain lend a hand and some electrons?

Measurements and data:

Brand............Compressor housing......Compressor wheel......Turbine housing......Turbine wheel

Turbonetics..............A/R .60................3.00/2.120 ..................A/R .82................2.525/2.170

Garrett.....................A/R .60................2.760/2.130..................A/R .48................2.300/1.912


Those wheels translate into (roughly) 56 trim and 70 trim for the Turbonetics and 50 trim and 74 trim for the Garrett (compressor and turbine respectively). Also they are T3's.

 

The garret turbo is close to a gt3071r for the comp wheel. The turbine wheel is a bit smaller then a gt3071r tho.

The Turbonetics turbo it very close to a GT2876r.

Post up some pic lets take a look of the turbos.

Also T3 T25 T4 what flanges you got on them.

 

Thanks for the help, they are all T3 flanges. I Will try to get pics up tomorrow. I also have a super 60 with shot turbine and compressor wheels :( Haven't figured out what to do with it yet

 

Here are the photos, turbonetics first:

















Need any more?

 

you want the second cause the first is HUGE.

both are t3/t4s.

second is 71mm, so 3071 sized. second is 76mm so 3076 sized, more or less.

 

That is what I was thinking and why I picked up the second one. Only problem with it is there are many cracks in the turbine housing :( Thanks for the help!
