RE: PRofec in a Sy

["Gronikowski, Joe" <joe@mail.pubrel.att.com>]

Ron and list,
	How hard was it to install the Profec in the Sy?  I have a 92 Ty
and I am getting a Profec model A, which is the same as the one you
installed.  I noticed he has an external wastegate and a TE-62e.  I have
a stock turbo.  Do you see this as being a problem?  Another thing; what
is a TE-62e?  Is it a Garret?  Where do you get one from?  I am looking
at upgrading my turbo in the future and am interested in learning what
option are out there before I purchase.  I have an ATR and Kenne Bell
catalogs.  I also looked at the Mitsubishi 20g.

Thanks,
Joe
