[s-cars] installing a hybrid turbo

[Eric Phillips]

Thanks again, Dave.  All this info is great.

In addition, it does not appear that we are forced at all to go with a KKK
hotside housing.  Javad at 034 Motorsport has a RS2-alike EM that sells for
less, and (get this) he'll put on any kind of turbo mounting flange that you
want.  All this for $700.  Now, couple that with relatively inexpensive
T03/T04 hybrids, you can get an EM, turbo and oil/water hardware for about
the cost of one of his GT turbo kits.  Upgrade your s/w and your injectors,
and it sounds like 350whp.

Can't hardly argue with that.  :)
