This is a rebuilt 1st Gen 7 Bolt 4G63. I bought the engine for a 2nd Gen GS-T and (its a long story-mechanic didn't wanna go through the trouble of the conversion) ended up not installing it. I paid $1750.00 for this engine and I am willing to take a cut to sale it. Its been in my garage covered up for a while and I need it gone. I'm going to ask $1000.00 OBO You can call or text me at 912-381-5794
