After pulling my smoking, blown t3/t4oe garrett turbo unit off my 72 z with 82 l28 et, On some advisement, I went ahead and bought a cx racing gt2871rs ball bearing, billet wheel turbo with an accompanying 3" v band flange and a t2 to t3 adapter. New unit has 60 ar / 53x71 compressor wheels and a 64ar/ 47x54 turbine side. with internal wastegate which I preferred for the simplicity. Well, now that I own this and have it in front of me, I'm fearful that this was a hasty and bad move. Turbo seems so small and the biggest corncern is just how much smaller the T2 inlet is and how restrictive this will be. Thinking I should abandon this install and go to a larger T3 setup, GT3076, GT35r or something similar and just deal with fitting external wastegate etc. I don't want to go through the whole process for no gain and feel I should just sell the turbo to a 4cylinder guy and start again. Any concise guidance would be much appreciated. Re my setup, here's the shortlist...
p90 head stock, 60mm tb, megasquirt, 14point7 wideband (great!), 3'' exhaust with soon to be 3" downpipe, 450cc talon injectors, supercoupe IC with 2.5" piping.
Running 15-18 max boost and seeking reliable 350-375 hp
