wanting to add a turbo i have a t3 sittin around my garage and would like to add it to my 4.9l i6 its and 89 efi if anybdy has done one before please let me know how you did it ty

 

from my experience... dont go with a cheap ebay turbo..

what brand is the turbo you have?

 

it was my buddies before he says it from turnonetics im fixin to purchase a new one tho his puts out bout 8 lbs of boost which would be good. heard more than 10 blew some dudes rings.

 

blew rings? anything can happen to anyone, dont judge by that, but on a stock engine, i wouldnt go over 8lbs with a very good tune.

 

i just bought a turbonetics today... shipped overnight cost me 979.00

 

What people need to keep in mind though, is that 8psi from a GT25 is going to be far less stress on a motor than 8psi from a GT42. You can't shoot for a universal PSI... every form of forced induction will have different effects at a given boost level (one might flow eleventeen times more air at 8psi than another one).

Be concerned with the health of the motor, and getting it tuned well. Do a compression test on the motor, and look not only for healthy numbers, but consistancy from one cylinder to the next. If you are within 10 or so points on every clyinder, you are good. Also do a leak-down test, make sure your fuel system is up to snuff, and have plenty of money set aside to get it tuned and rebuilt if things go south. The 4.9L is a stout motor, and begs for a nice medium sized single turbo. A simple log style manifold would make that baby spool up quick style.
