Ihave a 2001 tracker (2.0 J-20) that spun a rod bearing, and while looking for a replacementI found the aerio engines though mounted transversly appeared to be the same engine (DOHC). Does anyone know if is true? I believe they might be 1.6 whereas the tracker was 2.0 but I just want to get it rolling again. I've found some wrecks with these engines but no trackers with 2.0's available in my area. Any feedback would be apprecaited. I'm contemplating rebuilding it but would prefer to just drop another in to cut down the time.
