Will 0.50 AR Compressor / .63 AR Turbine work for my near stock 99 GTP?

Wondering if this is a reasonably sized turbo for my stock block/heads/valvetrain GTP. Not planning on running more than 10-12 lbs of boost for a while.

Mainly wondering if the compressor size is too small. Turbine size seems right where I'd like to be at.

Let me know your thoughts please.

Thx!
 


Those numbers are the compressor and turbine housing ar numbers. They tell us nothing about the size of the turbo itself. Could be a way to small 25mm or a huge turbo. Need wheel measurements to determine usefulness.
 
True. I totally forgot about that part :-P.

Slow fiero I have to say, those are some wonderfully beautiful 60' times. Stock 4t65 handling that ok?
 
Not even close. I've broken a 4340, and 300m input shaft. And killed multiple chains. Although, the 4340 input shaft and 7/8 chain lived for years with the m90 setup running 1.54-1.6 60' times. After I went turbo all hell broke loose lol. Now have GMR 1" chain and aermet input shaft, no issues with them so far.
 


Haha I thought so. Thats wonderful... Got any videos of you running at the track? I'd love to drool over them :-)
 


The 57 trim version would be better. I run it on my honda.

The first zzp turbo kits used a 57 trim... those cars to touched high 11s with minimal/no motor work.
