The car is an 1987 supra turbo, at first i thought it had a blown turbo. So i bypassed the turbo and ran as an N/A, but it is still smoking a decent amount. Is it because of the oil still left in the exhaust from when the seals in the turbo went bad? the car doesnt overheat nor does it show any other symptoms of a BHG. Should i jus get a N/A manifold and exhaust? When you first start the car there is no smoke, but then after it warms up a bit there are a few wisps of it. While driving though there is some, but going up a hill it got really bad.

Thanks

Oh yeah white smoke = coolant, blue/grey? = oil? the smoke doesnt have a sweet coolant smell to it....

it runs smoothly, but im sure its slower than a regular N/A because of the lower compression due to the gte cams

blue smoke means oil.
In most cases for these cars, blue oil indicates a bad turbo or bad valves.

White smoke means coolant.
If the smoke doesnt smell sweet, I doubt it's coolant.
If you think the car has a BHG, have it tested. Most places will do a block test for under 50 bux.
