BUILD THREAD 86 GP 2+2~Blown 6.0

[81cutlass]

I struck out with the local yards on getting a drivers side inner fender extension so I ended up trading some parts with another member (Thanks Kevin!).

Installed it today and we're good!

And time to work on the filter. I have always just had this cone filter in the fender, but I'm looking to move it out of the engine bay for some cooler air.

I've always just ran a J pipe into the headlight bucket for cold air at the track, but I am looking to do something like this all the time, and now with the inner fender liner I feel a bit safer now.

Problem if I just stick the filter on the bottom of the tube it sticks down too far so I'm not too keen.

I need to decide if I want to put another 90 on the pipe and point the filter back, or drill a 4" hole in the inner fender and route my J pipe 10" farther back and then put a 90 on that and point the filter forward.

Then I need to find some 1/16 or 1/8" plastic sheeting and cut to shape & bolt to the bottom of the car as kinda a air dam of some type and keep any water out of there.

Those inner fender extensions are like hen's teeth. I lucked out and found an NOS one on one side and Donovan pulled the other off a car up there in Calgary for me. He even cleaned it up and painted the bolts. What a guy.

Yeah I thought they would be a no problem part to find in the yard I hit up that has probably ~250 G bodies but I found out they are 81-87 GP only and the yard only had 2 GP's. Of course 3 of the 4 extensions were were destroyed and I grabbed the one that was mostly there but the bottom tab was broke off.

Kevin mentioned he found a few GP's and this was the only good one on them all.

These are a part that is screaming for a repop.

Pulled vacuum on the AC system last night and seemed to hold so I let it sit to make sure it's OK

And it didn't hold overnight.

So now I gotta hunt down a tiny leak. Great....

Tiny leaks can be a royal PITA to find. Often easier to charge the system with dye for a day and use a uv light to find the leak

I know your pain, the wagon lost its charge over the Winter. Weird. And painful.

I was going to ask, how do you trigger the fan when the AC turns on with the LS?

I have the AC clutch signal wire from the G body chassis AC harness just going straight to the AC clutch. Basically using nothing LS PCM related at this point to do anything AC related.

I realized I have no method to turn on the electric fan when the AC turns on. I can't just give a second feed wire to the existing electric fan relay that the ECM controls with the coolant temp switch since the LS PCM controls the fan via switched ground and all I have is a switched 12V.

I saw some people just send the G body AC 12V signal wire to the PCM AC request pin and then send that wire to a relay which then goes back to the AC clutch. However, I don't have any of the LS based AC pressure switches in my system however so I'm not sure the LS pcm will work unless those are hooked up.

Sadly I think you are right. I had a little charge left over in the high side of the gage manifold that I shot in the system, maybe 10 psi, and I heard a slight hissing coming from around the drier, so I have at least a possible source to start looking, but not anything great.

Dur, never mind. I forgot to check LT1 swap. Yep, thats easy.

Finally found a steering wheel on fleabay to replace ole beef jerky.

Factory 86-88 gt fiero wheel with the leather in 8/10 shape. Best part is it's darker and matches the seats better anyways.

It was $75 so cheaper than a recovered one and I think the reason it was cheap was because the plastic trim was broken but that was fine with me since I swap the 2+2 set on since the offsets are different.

I just need to get some 1/8 rivets and I'll get it back on!
