3s-gte in a Camry?!?
'89 Camry Alltrac
Looks like a nice waste of money...
There isn't much power to be had out of a 3s-fe without forced induction, but the kit linked there is not the right place to start.... (poor quality parts, turbo is too large, none of the parts will fit without EXTENSIVE modifications, etc.)
Cost, reliability and speed - pick two.
