I am trying to put together a turbo kit for my Si.It has a stock motor and I was going to get hondata for the ems.I found this turbo on ebay http://cgi.ebay.com/ebaymotors...ZWDVW and was wondering if this would be to big for a DD?I don't care for the T4 housing but if I could get it way cheaper than new. I could get a T3 housing.Let me know what you think.

 

A little big for your application.. I would look into a T3/To4e turbo or maybe even a GT28RS..
