I have forgotten something I am sure. I will add these items in as I remember them

I had purchased a whole 91 Deville around the first of April that had a 93 4.9. It was installed but was never finished. There was a problem with the different 91's round 7 wire transmission plug and the 93's 4T60E connector. I had removed the engine in mid April and cleaned it up for the install. I removed the entire engine wiring harness for my swap. $400.00 for the whole car.



I had decided to go with the 93 4T60E. The 88 coupe was a stick shift car. I located and switched over everything needed for an automatic. Fierocarparts in Ft Worth, Texas. and I traded some of the things out with each other. I think he got the short end of the stick. $40.00 gas and eats for one day. I kept my 88's manual CV axels.
I removed the valve covers,and located an extra one with the oil filer hole. The valve covers were nasty, as the black finish was peeling bad. I had them bead blasted and painted the with some epoxy silver paint and a coat of clear on top. Free, swapped some parts the shop needed for the work.

I had located the correct transmission mount brackets at a wrecking yard in Lufkin,Texas. About $15.00. FieroAddiction had shut down and was not selling any engine mounts. I was able to locate a CAD image of the front engine mounting bracket, and had one made at a local welding shop, about $25.00
Mount photo to go here soon.
I am using Micky_Moose's idler method to rout the belt http://www.fiero.nl/forum/A...050818-2-052483.html
Spent a few hours fitting it on the 88 cradle and rolled it under my 88.


Raised her up in the engine bay

Today I removed my drivers seat and laid the 91's fuel injection harness on top of the 4.9. I fed the ECM connectors into the cars cabin threw the square hole.


After an hour of untangling the wires I plugged in one connector, the distributor one. There is about 40 inches of excess wire I'll have to remove so I can lay it out and get it routed where I want it to lay.

I am using Mickey_Moose's wiring thread to build my harness. http://www.fiero.nl/forum/Forum2/HTML/098096.html
After I finish the fuel injection part of the harness I will add the C203/C500. This is where the two will join together. I wanted to have the biggest part of the harness on the bottom so the rest will not get tangled up while trying to marry the two.

I have purchased a muffler from a place in Canada that custom builds , and a 89's 6000 driver side CV shaft. I have a new AC delco 88 V6 fuel pump to drop into the tank.
More later, tired of typing all of this up..

It seems you planned to do a lot of work with the engine inside the car.

I am slowly preparing a 4.9 for a swap, collecting parts here and there. I planned to build the harness with the engine outside.

I ordered mounts from fieroaddiction and also a memcal reprogrammation but I never received them. He got ther money I got nothing.

My swap is for a Formula, so for sure I will follow yours.

My 88 coupe is in process as well, torn into a million pieces in the garage. When complete, 7730, Allante intake, centerforce clutch, I have most of the parts, its the little things that keep hangin me up (don't forget the flywheel bolts....) Should be a heck of a ride when she's finally rollin....

Well, as the owner of an 88 coupe with the 4.9 for 3 years now, I can tell you that you're gonna love the swap. It will be worth every ounce of effort and then some. Keep us posted on the progress.....

Here's mine.

I am just doing the wiring with the engine in the engine bay. I want it to fit right, and look nice and in orderly fashion. I am gonna remove the engine to have my exhaust made and fitted up. I will add the idler pully , AC hose and that type of stuff before I place it back in the car. I should have done these before I raised the engone up in the body, but I wanted to get it up in the bay so I could finish up the wiring. It went up and in very easy, I had more trouble raising up my Duke a few years back, stuff hangin up on the rear. My transmission dipstick got hung up on this one. I had to push it closer to the engine about 1/2". The rest was a piece of cake.

Looking good Joe! Can't wait to see it in person. I'll let you work out all the details and then I'll pick your brain! I sold my 88 GT this last weekend so now I am working on getting the Fino completed. I have to fix a couple of things on the GT for the new owner BUT mainly focusing on the Fino.
Keep us posted!

Why fight to be accepted by people you don't actually want to be like?

...I find it way easier to built the harness in the car - easier to get the correct lengths and run the wiring where you want and it fit. But, whatever works for you.

Just following you and Fieroseverywhere's advise. I've had no real problems so far. I have misplaced my Bakers Electronics VATS bypass, and my 88 V6 oil pressure switch. I'll have to order a new ones, or just plan on letting Stickpony remove the bypass. I'm glad the bypass was only $25.00.

Micky_Moose, in one of your pictures I can see a chrome airbreather. What size was it? Did the breathing of hot air effect the running of the engine? I am thinking about locating a S10 4.3 V6 air breather that I can point to the air intake and attach a flue to it. If it will fit flat in TB area.
