So we didn't start until the evening, as a result things were rushed but I think we got everything together (it was dark). Reconnected the battery, turned the key, accessories powered on, car cranks (we're in business!!), took a bit of cranking but eventually once I presume the fuel rail started to pressurize, the car started!
Now mind you, the mid-pipe that we attached didn't completely bolt on because the people that pulled the engine cut the studs on one section of the manifold so there was not only no muffler but a HUGE exhaust leak at the manifold / midpipe connection. Needless to say, the car is LOUD under ANY load. At idle, the car is pretty quiet actually though with a bit of a rumble. Something is wrong with the shifter also. I can't shift into reverse and the connecting rod of the shifter seems to hit the driveshaft when trying to go into 2nd. This is a pretty bit hindrance at the moment and I'm not sure what to do about it as of yet.
First things first though, I need to get the car into a friend's shop to try and have new studs drilled for the exhaust manifold if possible and to have a muffler / muffler hangars welded also.
So far I can't determine the difference in power because the car is so loud that I don't want to punch it and because the car has a fresh clutch that needs to be broken in.
No pictures during the install due to the rush but I'll have some eventually.
