So yesterday i traded a 96 civic DX for this beautiful 99 gtp. everything looks mint! car has a ton of mods but the engine is locked up. already has full SLP exhuast, F body front brake swap with braided brake lines, built trans with a cooler, and was told it had 383 hp and ran a 12.8 before it locked up. havent had time to really look at it, but the engine oil was a 2 qts overfilled and when i drained some oil coolant also came out. tried to just start it for a second to see what knocking the seller was describing and the starter wont turn over the engine.
