I haven't run it at a track with the new stage 2 yet so I'm not sure exactly what its running right now. When it was running well with the old computer I ran 15.5 at about 90mph. (That was last May). I hate to sound like a total noob but what should I look for to know the timing belt is/isn't working and how do I adjust the timing? Also, how should I fix the exhaust if its plugged? Or if anything else is plugged for that matter.
The exhaust is about 1 7/8" stock, really bad. I get my exhaust from Turbosunleashed.com, 3" rules but is costly. Consider at least a 2.5" mandrel system and a straight through muffler. If you want a cat they sell a high flow too. I don't run a cat because the cars pass without them and I have no morality issues if they pass.
The trap speed needs to be over 95 MPH stock. The timing on the cam is more difficult and you need to buy a book and find the marks.

so I would change a belt at this point too, then your good for at least 40,000 miles. I would also get a roller cam mentioned. The cam may not be working right, the sliders go flat. The oil today doesn't have ZP in it anymore and slider cams get chewed up. A junk yard 88 2.2 TBI car is a great place to get a cam and follower set. I run the Neon 16v DOHC MP lash adjusters in my 8v heads with a couple washers. Cheaper and last longer, not to mention allow real revs.
Next is distributer timing. Get a cheap timing light and remove your air box. The timing marks are in the square hole under the air box. Unplug the water temp sensor in the head, the fan should come on. Then time it for 12-14 before, 14 with a stage 2 MP computer. The wires are a down fall to the 2.2, along with the head gaskets. New plugs and wires are needed, I buy new wires every year period. MP gasket and bolts for the head from FWDperformance. This is needed to keep water out of the oil and give compression. Other than a 3 layer MLS everything else leaks. Torque the MP gasket and bolts to 85 ft lbs, do not torque stock bolts that far as they go to 70. Head gasket is a 2 hour swap, piece of cake. I spend a 1/2 hour on a cam swap. Timing belt is the longest at 3 hours, yes a head gasket takes less time. Remember a good running 2.2 has 2 HP per CID, a few good matinance items and they are bullet proof. Miss treat them and boom as they make way to much power for there size. Don't run a boost controller, they won't pull boost with detonation. Run a new computer for more boost. Better oil and fuel cleaners are required, don't run cheap gas.
Once you get deaper into working on them then look for more power. I run mid 13s easy with a GLHS with little done and they are reliable with great gas mileage. I drive my 86 with the old computer and engine like a robbed a bank with the car and got 28 MPG in town. Get a FWD computer and a wideband and you can trick the computer for 16:1 around town and get over 35 MPG. Most likely 40 MPG in a 87 GLHS and still be over 250 HP. But get some basics done and get it running right, just running right for a while may make you happy enough.
