One of the older members, 1337ssei, called me at 1 am one night earlier this month and asked if I wanted to swap to the L26 UIM. Well, yes! I packed up, left, and arrived at his house just past 2 am. Here are some pictures of the tiny meet. Some may see I haven't yet finished cleaning up and polishing the UIM. That'* because I planned to polish it and have it clear powder coated. However, this aluminum corrodes very quickly. I figured I would get an early start on the polishing, but it looks like I'll just delay the powder coating and leave the polish job half-done. Ultimately, I'll take off this combo and put it into the 94 for what I have planned.
I used the PCM housing as a screw and nut retainer. Everything but the coolant elbows was very easy to do. We tried to leave the rear bracket on the whole time, but it is too hard to manage the engine that way. Odd alignment and a new coolant elbow springing a leak had us put on the same alternator three times! See if you can follow these pictures. The SLE has had a PRJ Performance tune and now uses 92 octane fuel, had insanely hard and fast shifts, and pulls very hard with some amazing power.
We noticed almost immediately that the L36 UIM had been leaking straight onto the LIM.
This is not how you relieve the fuel system of pressure before removing fuel injectors:
The stock fuel lines have a point where they love cracking. Do not remove them from the shown clips, and you shouldn't experience issues.
It'* not plastic, but Nylon 66. And it cracked. Granted, it was by the throttle body, and most likely due to improper torque specs.
GM made a big mistake with the coolant elbow, because of which we had to redo the side accessory bracket. In the provided picture, 1337ssei is employing a technique not at all recommended to take out pieces of the broken elbow.
And now, this is the installation of the ported LIM, L26 UIM, and L67 throttle body.
