Finally got time for the Z
Posted: Mon Sep 12, 2011 12:34 am
Been a while since I've spent any time on the Z. Got a lot of stuff done around the house, so I finally have time to get the Z back to road worthiness. Not sure how long it will take right now, just gonna go with whatever I decide to do while I'm working on it. First, I'll post some recent pics...






So that's how it sits for the moment, well mostly... Engine is slightly more disassembled then in those pics. Engine hoist is just there because I was too lazy to fold it up and store it somewhere else at the moment.
Sooooo....
What I plan to do is port match the manifolds, get some 1999 3400 injectors (because that's what my ECM is tuned for), build headers (180* headers to be exact), get rid of abs (for header room, and I don't want it anyways) and get it back on the road. Plans are subject to change (hopefully to add to the list, not subtract), but it should be finished by then end of winter if not sooner. As long as something else important that needs my money doesn't come up.
So, on to the manifolds...






As you can see, dis-assembly lets us see how clean it is inside the engine. Reason for tear down is coolant in oil, aka bad LIMG. Engine only had about 20,000 on it, but overheated, and is probably what caused it to go bad so soon. Took the opportunity to look for other problems, but so far so good. Had a weird missfiring problem (causing bad shuttering/jerking while driving), but I'm guessing that has more to do with a sensor issue and not mechanical. Would get worse the more I drove the car, replaced crank sensor(along with plugs, wires, ICM, crank sensor wire, coil packs...), but might have to try it again... Any other ideas would be greatly appreciated. Been trying to trace the problem almost ever since I swapped in the 3400.
Then, here is some of my work with port matching...










So there it is. Comments, questions and suggestions?
Nice to be working on it again, will be even nicer when I get it back on the road.
