[net.auto] Turbo, or not Turbo?

partha@gatech.UUCP (Partha Dasgupta) (02/08/85)

     I  recently  test  drove a Mitshubishi Tredia Turbo. To say I was 
impressed is an understatement. If I  had  the  money  I  would  have 
bought  it  on  the spot. Not only does the car have phenomenal power 
for something that looks  like  a  econobox,  but  the  handling  and 
general feel is very good. Looks well made too.

     Since then I have had several questions regarding Turbo equipped 
cars: 

1) Is  using  premium octane fuel mandatory? (The price of that stuff 
   is scary). Would the use of regular gas cause the engine  to  bite 
   the  dust?  What  about  moth  balls? Do they work? Are they safe? 
   (This is in reference to an article which claimed  moth  balls  in 
   gas improves octane rating)

2) The  dealer  (and  a  sticker on the door) were emphatic about the
   great importance of changing oil every 3000 miles. That  is  okay, 
   but can I use the synthetic stuff? Does the recommended oil change 
   interval remain the same for synthetic oil? (I  am  worried  about 
   its effect on this elusive turbo gizmo.)

3) Does  the  turbo  have  any  effect  on  the life of the engine. I 
   noticed that the ordinary Tredia has a 2.0 liter engine, rated  at 
   about 85 h.p., but the Turbo model comes with a 1.8 rated at about 
   110 h.p. (I am quoting the h.p. rating from memory, and may  be  a 
   bit off.) Which implies that the turbo really packs a lot of power 
   into a small engine. Doesn't that in any way affect its longevity? 
   (Increased wear, torture etc.)

4) How  reliable  are turbo's in general? What are its failure modes? 
   It seems to me (logically) that the  failure  of  the  turbo  unit 
   should  should  not  make the car undrivable (except for a loss of 
   power). Am I right? Can the turbo be disconnected?

5) Last  (but  not  least) does anyone on the net have any experience 
   with  the  '85  Tredia/Cordia  line  from  Mitshubishi?  Also  any 
   information   regarding   prices   and   dealer  markups  will  be 
   appreciated.

     Please  send me mail. I will post a summary if I get requests to 
post the information.

Thanks in advance.

I am an avid experimentor.  After reading the article on
mothballs I ran out, got some (the naphthalene kind) and
dumped them in my tank.  They did not cause any problems
and seemed to give smoother power.  The octane effect,
however, I cannot attest to as my car is a 1980 Honda Civic
and eats anything.  (Why put the mothballs in then?  Well,
I *TOLD* you I was an avid experimenter... Give it to
Mikey, he'll try anything...)

Consultation with my CRC (Chemical Rubber Co.) Handbook
yielded info that coupled with my Organic chem book
leads me to believe it should work and be safe.
