"Turbo Ready" Throttle Body For

91-94 Non Turbo Style Eclipse/Talon/Laser

This is a popular upgrade for both the 1G & 2G Turbo cars. The advantage of using the non turbo TB is in not having to choke down from your IC pipe to the restrictive 2G Elbow. Just connect the IC piping to the non turbo TB snout with some flex hose.

1991-1999 4G63T Gaskets

Gaskets shipped to a US address only

The first two gaskets measure 60mm but are not recommended for use with a bored 1G TB because the RTV sealing bead would be partly cut away when the gasket opening is enlarged to 63mm.

In place of gaskets, I recommend using a skim coat ( 1/32" thick ) of sensor safe RTV applied to the intake and the elbow and allow the sealer to dry to the touch before bolting the parts together.
