This is a high quality after market oil pump for the 1993+ DOHC Dodge Stealth and Mitsubishi 3000GT. All DOHC engines, including turbo.
If you use this on a turbo car it is recommend to swap the relief spring from your old pump (its under the big nut). The NA engines use a lower pressure setting.
We use this in our billet oil pump builds and on our shop car with zero issues, if anything its an improvement over the original because the back cover has an extra bolt and is therefore more ridged.
DOES NOT FIT 1G 91-92 cars.
Swap the relieve spring from the TT pump you had into this one and torque that gold nut to 30 ft/bs.
