Would this be a good idea with this set up???

[3.8L V-8 eater]

I was looking at a turbo with a stock housing, but all the guts are upgraded. It's called a # 57- RHP trim set up, and is suppose to be able to support 225 more horse power than the stock turbo,and is brand new. I haven't upgraded my signiture since getting some upgrades this winter that are not yet installed, but would be before putting on the turbo. They include... Dutt neck intercooler, power plate, test pipe, hot wire kit, and #36 injectors with a poston's chip burnt to match. Everything else is stock. I don't know much about the TR other than what I read on this web site, and i don't know anyone who owns one of these cars personally. Any input would be appreciated.
