Ok Im getting the courage and the money set up for the turbo project again, and im probably gonna go with a used T3, but im not sure what the impeller sizes should be. Im planning on putting it on an 88 Accord LXI (fuel injected, A20A3) , and it wont be reved past 6-6300 so im thinking a t3/t4 would be overkill for a low boost setup, so the T3 looks like a viable alternative, im just worried about it being laggy or having a bad top end. Ive seen alot of saab t3s around... are they any good, i think they were usually like .42 compressor .48 turbine... oh yea and for the water cooled turbos, do they last longer than the just oil cooled ones, and how much harder are they to install?

 

T3 with .60/.48 from a Thunderturd or Mustang SVO, if you plan on turning up the boost in the future.

Hell, the Saab turbo will be just fine along with almost any other OEM turbo you might find. Will spool quick and should be able to feed it on the top end no prob.
Get a water cooled. Ford used non-water cooled on the early 80's Mustang turbos, they learned their lesson and switched.
