No, it's not any visible belts. I've played with those. It really sounds like it's coming from the timing belt area. Anyways, it just gives me an excuse to swap for the engine I desire. I'm not sure if I want to go with the Type R motor or the GS-R still. That's a pretty nice price difference. I can afford the Type R motor, but do I want to afford it, lol. I'm just worried I won't be happy with the GS-R motor. Decisions, decisions. I'm looking to do the swap a couple weeks after I get the car back from paint/body. Probably should have done the swap before paint, but had an opportunity to get the paint/body done for cost, so...
