WTB Holset for 500whp on 2.5l BMW
I am looking for an hx35/hy35 if they can flow enough air for 500whp... not necessarily going to get there, but if they can flow it, i'd like to try. Going on a stock M50tu with arps/hg. Let me see what you nigs got, only way I'd pay big $$ is if its new/near new. They go for 600$ brand new on ebay so dont bother ------lipping me. GG.

I have a holset he351cw (basically a hy35w with a bigger compressor wheel) it will support 500+whp. rebuilt by a professional shop comes with a 6 month warranty from the time I ship it. I started polishing the compressor housing. here's a pic of it as of this morning.(before I started polishing it) I need the money so you can have it for $450+shipping. 
let me know. no low balling please. this is a steal of a deal!!

yes it is internally gated. I cut the bracket for the actuator off because I was going to run an external but I can re-clock it and weld it back on where ever you want it if you like. the stock actuator is set pretty high(like 20-23psi) which is one reason I was going to run external. I've never seen any holset set below 17psi from the factory so unless you have the internals to run high boost all the time you may want to consider an external gate, or a aftermarket wastegate actuator. I can transfer the warranty by just calling my rebuilder and letting him know about it. as long as I write the sale date and initial it he will honor it. i bring him alot of buisness and he trusts me. been working with him for 6 years.
