13g Turbos

The following pics are of the used 13g turbos that I purchased. The front turbo had damaged fins on the compressor wheel. The wheel was replaced and the turbo was rebuilt by GT PRO.

Turbo Swap


Here are some pics and some of my suggestions for a turbo swap (applies to any TD04 direct replacement turbos). I primarily used the
Turbo Swap Guide by Errin Humphrey. I will not reprint the info from that web page, but I will include any relevant notes or important differences from that guide, based on my experience.
(Please note that I did find this guide very helpful, and any additional comments I have are only intended to be additional help to others, and in no way are intended to be negative criticism.)


I used the parts list to order the parts that I felt necessary. (Having the necessary replacement parts on hand is important for making things go smoothly.) I ordered and used most everything on the list with the exceptions of: front and rear oil return lines, A/C line o-ring, and plenum manifold bolts. Definitely order extra coolant line gaskets (MF660064).

I did not go through the preiminary removal steps in order, and I started right in on getting to the front turbo.
For the preliminary steps, I did not find it necessary to:

EGR Blockoff Plates


EGR blockoff plates were made for the EGR valve (located on the rear passenger side of the plenum, near the throttle body), and the EGR pipe (located on the rear driver side of the plenum and connecting to the rear o2 housing). There is debate over the usefulness of blocking the EGR system, as to whether it will gain any power, or stop any leaks in the intake system. Whether or not those are relevant, blocking off the EGR does make it significantly easier to remove the plenum because of not having to fight the EGR pipe + gaskets, and the EGR valve during the removal and reinstallation.

Front EGT Probe Tap


A used Autometer EGT probe was rethreaded to tap into a 7/16" nut, and the nut was welded into the front exhaust manifold. The front upper heat shielf was cut and the front metal intercooler pipe mounting bracket was modified to allow clearance for the EGT probe. I do not have an EGT gauge at this time, but the turbo swap was the perfect opportunity for adding an EGT probe, and the EGT gauge can easily be wired to the probe at a later time.
