Re: [DML] BAE Turbo Documentation

Bruce is right on about the timing and the coking.

I drove a DeLorean with a BAE kit and it to didn't seem to be 
spooling up. As it turns out, it had never been rebuilt and was 
probably long overdue. With that in mind, I have heard that the Rajay 
turbos are difficult or troublesome to rebuild, but I cannot comment 
from personal experience.

When you have the turbo off the car, take pictures and measurements 
of it and post the info here.

When you take your turbo to your local specialist, ask them if there 
is a modern turbo that will work for this application. If you can 
find one with the same turbo manifold flange size, then you will save 
yourself a lot of headache. Here is the link to the Rajay section of 
Turbonetics web site (

Whether you replace or rebuild your turbo, consider installing a 
Turbo Timer (
id=198&pageNum=1) or a Turbo After-Oiler 

Good luck,
