Has anyone turbo charged a JT-code engine?

I was toying with the idea, and was wondering if people had much success. I
realize that the motor does not have knock sensor and that there are other
differences (CR, oil squirters, etc..). However, I was thinking about
topping off the JT code motor in my 87 4KQ with the head, intake, exhaust
manifold, and turbo from a MC motor. (unfortunately the bottom end of the
donor motor was junk) To handle boost/knock issues, a friend of mine has
grafted the APC boost control system from a SAAB to his turbo'ed BMW 635
with tremendous success. For those of you not familiar with the APC, it is a
stand alone system that uses a knock sensor, pressure sensor, and solenoid
to cut back boost when knock is detected. They are cheap and plentiful in
any junk yard and easy to remove....
I'm thinking of going with modest boost (5-8 psi). Any idea if the CIS-E
system from the 4KQ can fuel that much boost or will I need to add a
supplementary system...
I know I should just do the full MC swap but don't have a complete motor and
don't really want to spend the summer under the dash...
Just wondering.
