Hi Guys... I just bought a 1993 XFi parts car (body and frame rusted out) with a great engine and transmission and would like to transplant both into my 1993 Metro Convertible. Any helpful hints/things to watch out for/etc??? Hoping to end up with a convertible that gets near 60mpg..... :hmm

Someone here, or on ecomodder.com, did the exact same thing.

Good luck on the transplant, please post pics. They are always cool, and there is not enough of the engine swap shots on this site. Pics.....

Johnny once suggested setting your camera on low resolution and taking a lot of before pics to refer to when you put the new engine in. Clean grounds, especially the one on the TB, take special care of the Alternator and Starter connections before putting the intake manifold on, proper vacuum hose connections, yeda, yada, yada.

I wish I had put a new clutch in before my swap. :smackface

That is not bad advice BB. A new clutch, throw out bearing, and pilot bearing. If you do not have a puller that will go that small. For removing the T.O. bearing. Fill the space behind the bearing with axel grease, you put it in through the pilot hole. It must be FULL. Next you need a punch the same size as the hole. It should slide through, but be a tight fit. Put the punch in the hole, and smack hell out of it with a hammer. Being very carefull with your fingers! You will have to do this several times. Some bearings have been in there a long time and really like it there. What happens is the grease can't be compressed. So it hydrolics it out. This is messy, but it does work. A slide hammer works but most of them do not have the attachment small enought to fit our bearings. And make sure if you use this method. That before you install the new one, remove all the greast mess. This is really important.

I might be the guy that Conche Blanco is talking about. I put an XFI tranny in my 93 vert (already had an XFI-like engine due to the custom camshaft). I might be seeing about a 3 MPG increase but everything is a little iffy at this point. Not a huge difference that I can tell. I'm really puzzled by this and it will take a few tanks of gas before I really see the results.

Hmmm, I may have found an answer. I had a low tire (pulled a huge nail out of it and did a quick plug job on it) until just a couple of hours ago. Took the car out for a quick drive to the bank and my mpguino said I was getting 60+ MPG (vs the 53-55 I would normally be getting). FWIW, I upped the tire pressure from 40 to 50 before taking the drive so I am not sure what to attribute most of the increase to:
tire not being flat
50 vs 40
new tranny

One low tire will not make it suffer that bad.

10 PSI?

All I know is that my mpguino is showing around 55-60 now vs the 48-53 it was showing a few days ago. I'm not sure what is going on because I wouldn't think that inflating to 50 PSI would have done that much. Anyway, it has renewed my "excitement" about doing the MPG thing again. I'm still upset about the horrible shake my engine now has but at least I am not having crappy MPGs right now. I was actually considering selling the car until today.

My dads car had 15 psi in the back two tires, and it didn't lose but 3 mpg.
