1990 GMC Sierra RCSB Turbo LS swap
#14
Gonna build 3 sets while I have the truck here.
We will
Be building fixtures for future kits as well.
Still deciding in sizes if parts.
This truck has so much room. I might just do a T6/4" down pipe and call it a day.
For all future builds.
But lots if customers love the current builds we offer for the 99-14 trucks.
More to come next week.

I have a 4" thick intercooler as well as a tru cool trans cooler stack in front of the intercooler. I have both of these mounted in the grill area above the bumper for max cooling. I think the a.c. condenser could have stayed if I relocated the trans cooler. This is on a 90obs
