JT to Turbo Question

[Nate Stuart]

No way, no how. The JT engine has too high a compression ratio to run much of 
any boost (especially w/o knock sensing). Albeit the JT isn't _that_ high of a 
CR engine, but no way would I ever run a turbo on it at all with no knock 
sensing. Not to mention the wussy cam, and lack of sodium filled exhaust valves 
as well... Whether the CIS system will handle it or not is the least of your 
worries. You'll still have to find a place for the intercooler, intake/exhaust 
plumbing(the 5kt IM is bass ackwards compared to the JT's) as well.

Take care,
-Nate
