making my own t3/t4?
 

I just got my turbo, and it's a newish, probably rebuilt, garrett t3 with the markings .50 on the compressor cover and 1.15 on the exhaust housing.

the exhaust is a split tangiental type and it looks like it will work well, but the compressor is hardly any bigger than my stock turbo. Is it possible to put a compressor and cover from a larger turbo on this turbo? I would think so, but I don't know what kind of things i need to know about the turbo like shaft size or center cartridge bolt patterns or something?

are all garrett centers the same for smallish turbos?

You're going to spend more money trying to piece turbos together than just buying what you want from a reputable vendor. Don't buy some crap turbo off Ebay, just pony up the dough and do it right. Turbos are cheap these days.
