Let me break it down for you two. Back in 89 90 91 there was a turbo 3.1 from gm it came in the tgp and tste. And the trubo engine's turbo kit will bolt to the gen 2 3.1 vin t like what I have in my 92 you all have a 3100 vin m and vin j there the same blocks same cubic inch but the fueling sytems are different. the earlier 3.1s like mine which is the vin t engine and the Lg5 which is the vin v engine they have the same fuel system setup. So if you have a gen 2 3.1 vin t its worth looking into the turbo kit for. Because the parts are damm near bolt up to the na engine.
