Default Re: Injector Housing to Head Port Match Issue

The mismatch while not ideal is not horrible, there is still a signficant improvement in flow without port matching. Porting matching can be done on the car.

**Use the gaskets to mark the area that needs to be removed

1)Tape off all of the intake ports you are not porting; and cover the motor to catch the aluminum. If you have secondaries only do the primary ports

2)buy tack clotch to put in the primary ports or spray some lint free cloth with WD40 to make it sticky to trap aluminum, push them into the ports. These are the back up layers

3)Put something on top of the cloth as a primary catch for the aluminum....cork, rubber stopper, or I used styrofoam balls from a craft store, cutting them in 1/2 and pushing them into the port on top of the cloth.......then soaking them in WD40, the styro is porous and caught alot of the aluminum splinters. IF using stoppers make sure you have a method of getting them out

4)Have a vacuum handy, stop periodically to vac out the splinters to reduce the mess...be careful not to suck out all of your cloths and stoppers, keep a finder on top of the stopper

5)Using the die grinder slowly start removing material, be sure to follow the angle of the port and not just going straight down

6)You only needs to go in an inch or slightly less to reap the "potential" 5-10hp, others have gone deeper.
