Build update - 4T80 3800 Turbo (Page 4/10)
LFiero67 MAR 07, 10:46 PM
Got the coil overs together tonight. This should allow for some bigger tires when this thing hits the road again. KYB struts, Allstar sleeves, Qa1 275lb high travel springs. 8.8lbs lighter per side vs stock, help counteract some of the extra weight the Transport spindles/brakes are adding.

Son and I got the pre-turbo hot side built this weekend. Last few joints to be welded up and then the turbo can be mounted. Be a few weeks until the downpipe and wastegate are built, but some good progress the last couple days.

Manifold is flipped front PLOG, with rework to Center two mounting holes, outlet cut off. 2” crossover with v band flange, 2.5” at union into a T4 flange. Still running the 6262 for now, but room to grow.

Got the downpipe made up today. Just have to have the muffler finish welded, and it is complete.

Still have to fit the wastegate and dump pipe for it, as well as add the two O2 sensor bungs.

Next up will be remounting scavenge pump, new scavenge oil line and run the oil feed to turbo. Then it will be ready to test fire.

Looking good!

Opened up the new gas tank from Rodney today. Looks like a nice piece, longer straps as my car is a 86, and new pads all included. Can’t wait I can get it in the car.










Didn’t post this when it happened, but the car runs and moves under its own power. Still lots of work to do, hopefully have it ready to drive next summer.

Since my last update I made the leap to Holley EFI. Today the car started for the first time with TerminatorX Max ecu. Few hiccups, but now it runs possibly smoother than with the stock PCM.

Updated previous post with YouTube videos instead of Facebook.

Sounds great!

I got a laugh out of the crushed/lopsided valve cover breather/filter.

You put a lot of thought into your "electrical board" behind the driver seat, looks very well organized!

Sat on it a couple times wiring everything up lol.


Just finished the board and got it mounted last night.
