Project: Big White Elephant! 88 GMC Sierra LQ4/4l80e/Turbo Build

Finally got the engine and transmission mated together after some issues with the TC and Flexplate not snugging up, thanks again Chris for helping solve that problem.

Much easier with the front end off! Painted the frame with Por-15 the and repainted the firewall to clean up the engine bay a bit...

Anyways here she sits. I started the install today and just have to get the cross-member fitted to the trans. Will try and get more done this week, starting with the harness, and get back to posting more pics.

Great looking build. I wish I had the time to do mine this way.

Thanks man! All I have is time... In fact this build has been ongoing for about 4 years now! I am starting to think its only the journey that matters lol

Anyone have knowledge of where I can find a good write-up concerning the 4l80e swap into an OBS, particularly the shift linkage, I see some have shortened it 1.5-2" and just want to be sure this is the appropriate method?

Not sure about the 4L80E, but when I put a newer 4L60E (cable actuated)into my OBS, I had to modify the original linkage bracket mounted on the shift shaft of the transmission to get the column shifter to work properly. If the 80E is cable actuated, you may have to go this route as well.

Thanks, I will be tackling that very shortly!

Been busy adding all of the accessories: water pump, ps pump, starter, and etc. Finally starting to look like a complete engine. Next I will add the exh. manifolds, crossover, turbo, and down pipe. Picked up a harness from PSI Performance (great guy to deal with BTW)!

It's been a blessing having the front end off!

A little off topic, but I have used many methods for removing stubborn studs/bolts and I highly recommend this nifty tool from Titan Tools.

Got the pipes and turbo mocked up today. These are used pipes I bought from a member here and everything fits pretty well. Need to rewrap the pipes and bolt everything up. Getting close....
