+1. Why do all this work and skimp out on an intercooler, it looks professional, but with any resonable amount of boost on a turbo, that big, your gonna be blowing hot air and knocking.Not sure why you have the MAF sensor BEHIND the turbo, but IMO it's not a good idea in practice. Although it may work now, over time, it will eventually fail because it is behind the turbo, (between heat from not running an intercooler and oil blow by from the turbo), it will ruin the veins of the sensor. :nono:
I'd say finish the turbo upgrade, do it right, THEN drive it daily.
You have a nice turbo, and of what IS actually done, looks good from here. I just hope you have supporting fuel mods, and electronics to monitor that engine with that turbo you attached.
