I figured I would start page 6 with a good pic.

I do have a muffling/resonater tip I am putting on. (Same brand as used on Ferrari's and Lambo's stock)

Here are my thoughts on it,
When Fierobsessed had it in his Indy he did not have any kind of muffler, his was loud.
My Turbo 3.4 GT has no muffler and just the tips, it is not too loud, loud yes but not too bad, much quieter than no tips.
My friends 4.9 has just the tips too, and his is not too bad either.
When Fierobsessed notched the cradle for his exhaust he took out one of the mounting points for a stock style muffler, so that was out too.
I want the best MPG I can get out of it, so straight through it is.
And being able to drown out the hon-duh fart can or vette next to me is just pricless.

I wouldn't mind quite, but it is what it is and if I find it being too much I can always do something else on it.

My Beretta had a completely worn out catalytic converter, so it was pretty much a straight pipe with a cheap muffler with a splitter at the end. It was louder than most cars but not annoyingly so. If I ever get to that point, my plan is to run the down pipe from the manifold toward the passenger side, then do a 180-degree bend back to the muffler in the stock location.

I have duals, X-pipe and cats on my Northstar--which is basically two Q4's--and it's not bad... not quiet but not nearly as loud as it was with the straight pipes.

Depending on how it all comes together I may just start it up with out the tip, just to see how loud it is.
But even then it won't be as loud at idle as it will be at 7400 RPM.

Here is the fuel rail bolted on. I used new o-rings on the injectors (They came with the gasket set)




Some of the shift brackets.




For the side bracket the holes are there, but not tapped out, They have to be drilled out a little and then tapped.
Make sure to use a good quality tap, like Craftsman, the cheap Harbor Freight taps make the hole a bit bigger and then the bolts are loose.






The lower side bracket on.

I'd just like to take a moment and thank you again for posting all these photos and tips. They're a tremendous help, since my swap is taking so much longer than I had planned and hoped.

The thermostat gasket is cool, it has one side that is sticky so it sticks to the stat housing and makes a good seal. I still used RTV on the other side as I hate leaks.






Other parts bolted on.




I got new spark plugs for it (AC Delco) and gapped them to .035 I torqued them to the spaecs on the cam covers.
The IDI cover is bolted down and ready to go.
As is sits now.






Now I have to bring my car to the shop and pull the duke out and prep the Fiero for it's new powerplant.

My swap is taking alot longer than I thought too. Thanks for the comments, I'm glad to know this all is helping out. I was hoping this thread would help anyone ever working with a Quad4 regardless if it is in a Fiero or not.

That's one of the issues I discovered when I disassembled my quad. In the winter my heater would only blow lukewarm air, so I figured my thermostat had slipped during installation allowing coolant to flow around it. Turns out I was right, but I also had a slow leak around the housing that I couldn't see with the engine in the car.

I was thinking about it and if someone did not use the sticky part and just put it on it would end up leaking. Prob due to RTV holding the sticky backing to the housing and just coming off of the gasket. So make sure to peel off the backing and use the sticky part.
