Mattwa's 3.4/4T60 Project (Page 67/69)

I really didn't want to make another thread just for this so I'll just say it here:

I think I went over this in the past, but I wasn't a detailed about it. I have been asked by a few people as to why I chose the 3.65 4-speed muncie over a Getrag or a different 5-speed when i did my manual swap, because I had the option of doing that if I wanted to. I used the 4-speed for a few reason:
1. At the time it was a free transmission.
2. It is the best "performance" transmission out there for a Fiero that was a factory transmission. It does have a performance edge over the Getrag, with a slightly higher FDR and a taller 1st gear (best part IMHO). The Getrag is just a very good compromise between performance and economy with its 5th gear.
3. This one is the major reason. Parts for the 4-speed are everywhere and for the most part cheap, the transmissions themselves are a dime per dozen right now, they are everywhere. I even have a spare one sitting in my garage! Complete opposite situation for the Getrag, finding a good one without 200K miles is challenging and expensive, and replacement parts are very hard to find and expensive if you do find them. $80 for a replacement input shaft seal, if you can find one.
And 4. This could be a myth, but I believe its true, that the muncie 4-speed is a stronger transmission then the Getrag, don't get me wrong the Getrag is tough too compared to like an Isuzu, but just not as strong as the 4-speed. I think its because the diff bearings like to fail on it and that causes stress where the output shaft bearing rides and breaks that little section of the case off.

Today i got the Quad 4 ign module cover in the mail that I bought from eBay. Its going to be used as appearance cover in the middle of the DTBI. I plan to have someone mill off the "Quad 4" lettering, and mill in the word "Fiero", then sand-blast and powder-coat it blue, like my valve covers. I have the correct size threaded rod to mount it, I just need to figure out how to keep it upright pretty much, I think I should ask TT Slick. It's looking more and more like his!




BTW: The fiero's are now covered in 6 inches of snow again. Yay.

Matt, not trying to knock you but what's the reasoning behind using parts that have dents in them?
Will they look better once sandblasted/coated?
Cheaper, availability, or something I'm missing?

I thought I stated this earlier, but I did not Actually make that intake. I bought it already built for a decent price, and I have re-engineered the throttle linkage, nothing else. Those dents had nothing to do with me.

I must have missed that. No problems though, I'm more of a function over looks kind of person anyways...

Scratch that, this project is still going on! I decided against selling it.

Today was the first nice weather day so after class, I put some coolant in (didn't take that much) and started it up. It does have a check engine light, which is code 43, knock sensor, because its not connected. The sensor wasn't right or something, either way have it connected mades no difference, short someplace most likely. I want to get that turned off in the PROM BIN, so that's that. But I started it up, and once it warmed up, it ran pretty good considering the exhaust leak. And guess what? Not more then 1 drop of coolant out of it, for 10-15 minutes of revving it moving it, letting it sit and idle, nothing! I even took a video, with my new phone (best video ever so far, love this phone).


Also shows my tail-lights.

The idea of getting an 88GT swayed me the first time, because it was rust-free and blah blah. I put to much into my car to give it away, if I do sell it, it will be for a highly modded Fiero in a trade.
