time to upgrade the turbo?

[wild_maxx]

new built motor going in soon and just wanted a few opinions from you all.

1. my goal is 300 whp, my current turbo is a straight t3 with a .42 a/r compressor housing and a .48 turbine housing. will this turbo be effieient enouf to make my goal? or should i upgrade to something like this? http://cgi.ebay.com/ebaymotors...&rd=1

2. i am running 460cc injectors, i am pretty sure they will be able to handle 300 hp but should i get some larger ones?

1) You'll need a bigger turbo to hold boost to redline...well, enough boost to reach 300rwhp.

Unless it's a T3 Super 60 compressor (sounds like it's not), then you're WAY of the map at +30lb/min of flow. Plus, that tiny turbine housing will absolutely CHOKE the motor in the upper RPMs.

That eBay turbo you posted looks good (the specs and such), assuming it's actually a new unit...and brand name.

2) 460cc injectors can do ~303rwhp as a MAX...I like a little room for error, but wouldn't be afraid to run ~290rwhp daily with those...then turn it up that last 1psi when needed.
