My Custom "rigged" Universal ISC motor

[Boosted98gsx]

After upgrading to the DVDT Fab Intake manifold and the Q45 TB, I was tired of idle issues, so I decided to take a stab at rigging up a universal ISC motor to put some drivability back into the car.

Obviously the ports go to a before / after throttle plate bung of some kind so that the motor can allow / not allow air to bypass the throttle.

Thing worked wonders.

Essentially, I took the underside (ISC / FIAV) portion of the Tb off, sawed off the FIAV, welded the now gaping channels closed, and milled out a plate and threaded some fittings in place. Pretty easy. Only took an afternoon in a machine shop.

Interesting. So all you have to do is tap into the intercooler piping and intake for the inlet/outlet. Where are you mounting the ISC?

Mounted it with some zip ties to some misc firewall parts.

yes, just need to run some hoses to a pre / post TB source.

What iscmotor did you use? Is there a isc motor that we could use that isn't so costly?

 

[Boosted98gsx]

That's just an OEM isc motor....

Thanks for posting this.

Do you have the FIAV hooked up on the Q45?

 

[Boosted98gsx]

No, all ports unplugged / blocked on the q45 TB

I had a DVDT fab intake manifold, and I welded a 1/2 NPT bung to the underside of it for the receiving of the bypassing air.
