Re: Differences in `84 & `86 turbos?



Mike,
 Yes, the A/R ratio is different between the two units, simple put the
size.The early cars (84/early 85) use an A/R of .63 (larger) and the late
models use an A/R of .48 (smaller), both have their good and bad points.The
smaller unit spolls up faster but does not flow as much air and does so
with more heat.The larger units run cooler and flow more air but have more
lag.Hope this helps.
