Re: Andy's 91' 80q

There’s room for a muffler under the passenger side rear seat
I’m debating about making one with a little copper and/or other crazy metals to get a different exhaust tone. Already going to have a Flowmaster under the trunk

Re: Andy's 91' 80q


I bypassed going up and around the diff on mine. It is now the first thing that hits anything. I plan on redoing mine to snake around. Your image looks like what I had I mind. 45deg over the CV. I kinda gave up fitting it correctly. Even the same box of amazon pipe but in 2.5 :D Hanger situation ...

Re: Andy's 91' 80q

:bangshead: there’s only 3 cat back exhaust mounting points
I’m gonna have to fix that. There’s not much room with a 3” pipe in a 2” ditch. I’m debating about just bolting the flex pipe back straight to the car with rubber isolators

Re: Andy's 91' 80q

1.9 bar / 13.5 psi or 2.2 bar / 17.5 psi?
That is the question
If I was to guess the intake hose at the throttle body popping off is its weakest link.
Bonding silicone to aluminum:
Permabond
Polyolefin primer
Permabond cyanoacrylate 105

Re: Andy's 91' 80q

Here’s progress so far. No oval tubing. Can’t get it to fit 😞 do you all run 3” tubing? I’m worried about ground clearance and melting things?

Re: Andy's 91' 80q

I shortened the downpipe a little to fit this
I hope haha. Wish me luck. 3” oval tubing. More ground clearance and will leave more room from melting the axle boot

Re: Andy's 91' 80q



Hello again. It’s been a long time. I decided to keep it. Too sentimental. The piston rings went. I’m going to be able to get a short block from Marc in about 6 months. Now that I know which turbine housing I’m going to use I can make the exhaust and intake as well.


Glad you kept it! I've ...

Re: Andy's 91' 80q

Making a downpipe is much more difficult than I thought. A new found respect for fabricators. Here’s what I got so far.

Didn’t have much luck the first two times. I’ve gotta make the intake and exhaust first so we can tune it properly. The intake ...

Re: Andy's 91' 80q

Everything is great 100 or so miles later. I needed a vacation from it. It turned into an obsession again and now I can relax. It’s back to it now.
First is the power steering doesn’t work. I used a mini cooper electric pump that’s not coming on.
Just ordered one today. This weekend I’ll finally ...

Re: Andy's 91' 80q

After starting it for the first time the second time around. Had a loose oil cooler hose and a leaky freeze plug. They are now fixed. Gotta get a plate and registration and I should also hook up the electric power steering pump. Not sure if that affects tuning. It is more of a load on the engine. I ...

She’s all back together again. So I called Marc for a remote tune. Over the internet and through the computer it started right up. Thank you!!
