Can a Eaton M90 or M67 bolt on to a 87 TR engine (8445 Heads & 109 block). Messing with the idea/daydream of a supercharger in addition to the turbo

How hard is it to drop the fuel tank and clean it out along with cleaning fuel lines? someone put sugar in my tank and it clogged all injectors. i decided that I am going with new injectors and pump but want to correctly clean the tank and lines so this isn't all for nothing. what tools do i...

I tested a new plug screwed into a spare head and sat the head on top of my engine (so I could see) while I cranked the car with the fuel pump unplugged. I ran each corresponding cylinder wire to the plug to check spark. what would cause all 6 plugs to have weak crappy orange/yellow spark rather...

Car is misfiring like the spark plug wires are wet one week after they actually did get wet. Checked terminals on both the coil pack and plugs and everything is bone dry. The car started doing this as i was driving and hit a few massive puddles. Ive had cars get wires wet and you just let dry...

Dont know if these 2 are on the same circuit but my opera lamps and cornering lamps do not work on my t-limited. Assuming it is not the fuses (which I checked) , what else could cause this. It is of course very possible I looked at the incorrect fuse , however, everything else on the circuit...

this is going to be somewhat hard to word but my best analogy is can you max out a MAF sensor with air like fuel injectors can be maxed with fuel. I mean watching a scan tool I know that it is designed to lock to 255 at WOT. Here is my main question/point, If the stock airflow is calibrated to a...

anyone know where to get a good used (or new if i have to ) A/C lines. My alky braided hose rubbed and wore a hole on my high pressure side over time and i need the pair of lines that go over the radiator to the compressor. Thats for the help. Also will the lines off of a carbed V8 or V6 work?

what does this take plumbing wise if converting from journal bearing? where do you plumb a water line? is there a kit to make this less of a pain in the ass? any downfalls from water cooled BB turbos?

what is the header to turbo gasket # for a 3 bolt T.A. header to pt-61/52S that can withstand the heat at that point and is the correct diameter. I guess it would be the same as stock. Also tell me what it should be made out of. I burned out part of the turd that is in there and am sick of...

What do I check and what are the "go down the list" procedures

What are the common causes you guys have noticed that are the cause(s) of running fine up until about 13-16lbs of boost and then car falling on its face from running lean?. I do not have an in car fuel pressure gauge but the rail gauge says its at 43lbs when in idle and O2s read around 800 till...

did ANY GNs have a factory column shift in 1987. I know turbo limiteds do, I have one, but specifically grand nationals? IF they could have a column shift did they keep the center consoel even though the shifter was removed?

What are weak fuel pump, clogged charcoal canister and clogged fuel filter symptoms?

If I look under the car is my torque converter and flywheel supposed to be in plain sight (because it is) or is there a shield that I'm missing?

What does it take to run a wide band O2? Is it worth it? How can it be made to work in a street/strip daily driver?

This is a fairly broad question but I have noticed I have been running very lean when I hit the gas until about what feels like the end of second gear. If I watch the scan master when all of this is happening, it will read about 0.50 MV like the fuel is not being richened up to compensate for...

Im replacing my pistons and possibly my whole rotating assembly. If i do the rods and crank in addition to the pistons is there ANY reason not to do a stroker crank on a stock block engine?
