Quad 4 swap (lot of pics) (Page 31/31)

Well I got most of it done today. Oil pan was fixed, yea Chris, and installed, BTW the oil pan gasket is reusable (per GM) shift fork, custom bracket, and all accessories transferred to the new transmission, transmission back in the car, cradle fixed and back in the car (it had a couple of cracks (I think I hit a rock somewhere, probably one of my off road trips (Yes I take this off road, nothing like flying down a dirt road doing 90mph )) Part of the day was waiting for paint to dry. I decided to paint my exhaust this time as I didn't have time last time. Here is a good trick for exhaust paint, use barbecue paint, VERY high heat, flat black and cheaper and better than high heat exhaust paint. I still have an hour or two tomorrow to finish it all up. Axles, sway bar, suspension, fluids, test drive and clean up.

I counted the turns and found I have this transmission.

I will add the calcs to show the differance

1992-1994
1st 3.50 13.79
2nd 2.05 8.077
3rd 1.38 5.4372
4th 1.03 4.0582
5th 0.72 2.8368
Axle 3.94

I went from this one

1991
1st 3.77 13.6097
2nd 2.19 7.9059
3rd 1.38 4.9818
4th 1.03 3.7183
5th 0.81 2.9241
Axle 3.61

So you can see it will be quicker in 1-4th with a lower geared overdrive in 5th
After driving it all this time I may get better mpg as I looked at the different years it came in and the 3.94 seemed to get better mpg as the power band and efficiency is higher up, plus the better 5th. I never owned a high rev'r DOHC before so I figured lower rpms the better, but may not be in this case, we shall see. 1st and 2nd are not too far off from each other, between trans, 3rd and 4th are a ways apart, 5th goes the other way. Either way I will be happy when the damn ratting is gone form the output bearing. It was hard to pinpoint as it would only happen sometimes, and only around some corners, on and off throttle but never while sitting still even under load. I found it as when I changed my struts I moved one of the axles and said "hey there's that noise" I had it since the install. Sounded like an exhaust rattle. And after going to the track a few times with the Quad, I wanted a faster trans, as 3rd is what carries you down most of the 1/4. And all Getrags have the same 3rd so it is the final drive that changes things. This trans, with the high rev limit, will still go over 200mph, not that a Fiero can handle that but still nice to know
I still have a few pics to upload, especially the custom bracket needed for this trans case.
I may have to wait until next track day later this month, as I may be going out of town tomorrow, we shall see. Even with the times I have ran so far I am the quickest 4 cylinder Fiero for the quarter mile list. I have yet to post times.

Now for some pics

Here is the crack in my oil pan



My new pan



Painted



I have to say, I pulled this from a Buick Skylark, I never want to do that again, there are so many things in the way of pulling the oil pan, in the Fiero I only had to drop my rear sway bar and the coolant tube to get at the whole pan. To get it out of the Buick it took alot of tools and a hacksaw to get it out.

Another trick I learned on the quads, to reinstall the spacers that go between the pan and trans. Make sure the spacers have no paint on the ends, and soak them in ice water for like 10 mins, It barely helps but just enough to get them in. Heres a pic of the spacer.

When my brother gave me his '92 GTZ in 2008 with a blown head gasket, I pulled the engine and transmission out the top. Hell of a job. Then getting them back in was even tougher.

In 2012 when I was junking the car I dropped the cradle. So much easier.

I love all the extra room in the Fiero engine compartment. Great tip about those spacers. Someone on the Quad forum made the point that they're crucial.

Update:
I lost all 3 motor mount bolts on the firewall side, so make sure to locktite them in, I used blue this time (I know most of you have natural locktite, rust, but here in Vegas, it is hard to keep bolts in)
High vibration engine and all.

And I think my old transmission may have been faster 0.3 secs on the 1/4, but it could have been the heat too, haven't logged MPG yet.

I can't believe it has been 5 years since I started this swap, I still love it, what a good daily driver. The power band is just awesome, more power band than most engines have RPMs.

I pulled this off of a K5 blazer, but most GM lines should work as they are mostly all the same size.






Please be more specific about which K5 Blazer this fuel line came from.
