Yes they are in fact referred to as Reverse Turbos by some.(Sorry for the typo above

)
This setup is to freaking simple to believe and yet proven as claimed for sound performance.
All the spool-up haters(turbo-lag) please dont bother trolling this issue. In a Tundra platform you'll be grateful it doesnt all hit at once. Pickups dont respond well to power adders unless some pimary traction issues are addressed prior to boost build ups.
So all the TRD fans best consider cost effective verses label trendy.
These turbo setups will smoke anything TRD will offer the public.Even with add-ons like injectors upgrades and tuneing,labor etc.,one would still be WELL UNDER the projected $7K for the TRD Blower.
DOHC motors and Turbos have alot in common,both pull steady up thru the RPMs without dropping ponies out/off at peak levels.
Plenty more but ........:tu:
