alright, fairly new to turbos but not cars/engines.

this is the turbo im looking at.
http://www.---------------/turbocalc...=1&map_sel0=62

im basically lost, I cant seem to find the turbo that matches that map. does 60-1 mean the compressor a/r is 60? does turbine wheel affect the map or just where the boost kicks in at? same with the housing? I want something that spools a little later in the RPM range due to traction

going in a 3.4L built with 10.5:1 compression. as it sits, n/a 220whp. planning to add 3-5psi.

 

The 60 in that description is the compressor inducer measurement in mm, thats the compressor size. The turbine wheel and housing have no effect on the map. Their configuration tailors the where boost starts. The 60-1 is a good turbo but I have experience only on V8s, I would think that you would want one of the smaller A/R exhaust housings on a 3.4 which would be around .69 if it's a T-4. or the larger for a T-3, about .82.
