Real Fiero Tech

You do realize that Google knows enough about Fiero wiring that you never have to guess, right?

I tried google for a good 15 minutes, never got anything but wiring details on the relay.

Ok I got the new fuel pump installed and the tank put back in. I decided I'd fix the issue with the return line dumping literally 1/2" from the pump inlet, so I cut the return line about an inch after it enters the tank. Series brought up something I hadn't thought of, that at low fuel levels the pump might start sucking in bubbles.

I'd like to get some more opinions, big issue or no?

I thought the return line outlet was that close to the pickup to help keep debris away from it and to keep the fuel from being aerated. Think about when you fill a bucket with water, if the hose is above the water level, there is a lot of agitation and bubbles are put into the water, if the hose is at the bottom of the bucket, the water has less agitation and is bubble free.

I would leave it stock.

That's what Steven thought too. Damn you and your stupid physics.

Looks like it's coming out

Didn't really find anything unexpected. I have a very minor oil leak from the oil drain at the turbo. It's minor, not causing any problems, but I'll address it. Wiring needs to be cleaned up in a few places. Other than that just dirty. I'm thinking the motor is sealed, that my clutch slip is caused by the getrag being a leaker. Car made the 60 mile trip today without issue, drove really well.

Oh. And as usual I forgot to disconnect the brake lines until my engine hoist is trying to pick up an engine via 2 rubber brake lines. I can't believe I haven't torn those, I forget every time and I stretch the CRAP out of them.

Replace them to be safe.. If you put them in tension you've compromised the crimps and liner..

I find it easier for me to leave the strut/upright/caliper, connected to the chassis and just drop the cradle with engine/transmission/axles. If you do it this way, on reassembly, you don't have to bleed the brakes.

Series is really good at spending money I don't want to spend.

Guru that probably is easier, to be honest I only do it this way because it's the way I've always done it. Would've helped this time too because now I have to disassemble all of that to get the getrag out anyway.

Stock rubber lines are... $15? Don't be a .NLer


My preferred method of lifting the body is via the strut towers, so I drop the struts with the suspension, BUT I unbolt the calipers and hang them in the wheel houses so I don't have to bleed upon reassembly.

Hmm. Got it apart, and there are no obvious signs of a leak, or anything that could be causing the clutch slip. The clutch slips at random. Some days it'll hold 100% of the time, even 5th gear full boost. Other days it'll slip 100% of the time as soon as boost comes on in any gear. Next I'll pull the clutch and flywheel off and check the rear main seal.

Nice progress

Did temp or humidity ever seem to have an effect on the clutch holding? What do you plan on for your next clutch?

Not that I noticed. I was hoping it was a fluid leak causing this one to slip, and that I wouldn't need another and I could reuse it. If I have to buy a new one, it'll likely be another clutchnet.

Beware, clutchnet seems to been very unreliable in the past year from customer service standpoint, things like sending the wrong parts and then not wanting to fix it.

Spec strait up lost the order I placed, and then called me a month later asking if I was still interested in buying a clutch...

I ended up going with a Bully stage 4 instead of the other two knuckleheads.

I was reading your posts about that, Bully sounds like the way to go. I really don't think it was my clutch or flywheel causing the slip though. To all of your more experienced eyes how do they look?
