That 70 size compressor turbo is too big for your stock engine & will not spool fast & will be inefficient for the low boost level you are only going to run.
In other words, it will run very poorly, do not buy it.
I just posted it because it was cheap & a faily large turbo.
This turbo would work perfect for your combo,. 63 A/R on the turbine housing for quick spool anything bigger will not get into boost that fast for your stock engine. I just cannot seem to find those specs on a low dollar Ebay turbo.
I would not recommend a turbo too big for your engine right now. I only am giving my own personal experience w/turbos on a 4.3 liter engine 262 CI a littler bigger, so I know first hand that anything bigger than a .63 A/R will need @ least 2400 RPM stall to be able to boost launch & get into boost fast.
You are going to run a manual trans so the load on your engine will differ than an auto trans.
I would not want you to get a turbo that will boost up really slow, not be fun to drive, & in general an overall dog of a car to drive..
I would like you to succeed & have a daily driver that can run 13's in the 1/4 & faster w/your better purpose built combo later on down the road.
My Syclone used to run 14's when I first got it. I have done some R&D & thinking outside the box on parts to add/bolt-on to my Syclone & runs 12.0 to this date.
I chose a different route than the norm & mainly a low dollar high labor program to get my Syclone to run decent.
The wide band tool got me closer to a decent tune in a short amount of time & is one of the best tools to tune with, that & monitoring engine knock/pinging. http://jandssafeguard.com/
