6nz with twin turbos

For on road use? I don't see the need, but hey I am sure it's been done actually I know it has, PDI has a kit to change a single turbo to double, most race trucks or trucks set up for competitions are set up with compound turbos so I don't know about the 58's and just stock acert twins but there are plenty out there with twins on them

 

There was a thread here a few years back about member that did this. However if recall, he had issues with heat, the acerts come with coolers, this individual install a cooler and had to play with it for awhile to get it right. At the end, he was happy with the response with the twins. I can’t remember what series he did this to but I know it was not a 5EK. This so-called up grade is not add on and go, you have to tune the ECM and like I mentioned, the air from the twins will have to be cooled.
