Head torque sequence for a 2002 3800
Need more info. Torque specs. for what?
horsepower : 200@ 5200 rpm torque : 225@ 4000 rpm
Ineed the torque sequence and tightening specs for a 92 GM 3800 intake.
I'm pretty sure this is that same 3800 motor that gm uses in my mom's 2001 buick Le Sabre. Her intake was the fiberglass resin plastic and the torque specs are 89 INCH pounds. Make sure you use the right tightening sequence too. 89 inch pounds is for the upper intake or Plenum. 136 inch pounds is the torque specs for the lower intake
No
Advertised Horsepower is--245 HP @ 3800 RPMs. Torque is-365 FT. LBS. @ 2800 RPMs. The Heavy Duty 454 has--240 HP @ 3800 RPMs. Torque is--370 FT. LBS. @ 2800 RPMs.
I think so, though the exhaust ports may be slightly larger on the FWD motor, but they are all GM heads.... they will fit but they are differnet the fwd have the fuel injectors in the head where the rwd has them in the lower intake manifold.
No
The 3800 Pontiac engine had bolt torque specification is 160 pounds. The head bolts should be torqued in 40 pound intervals.
don't think motor mounts will work - look for 92-99 3800
Ignore the specs. Work inside to out, tightening a little at a time. Should take you 6 or 7 runs through. Make them tight, but dont force them. I tightened to specs and had horrible leaks. With this method, perfect.
3800 gm (supercharged does not change) Mains: 30Ft-lbs, then tighten 110 degrees sides:11 then tighten 45 degrees Rods:20 thentighten 50 degrees I got this from my haynes manual, I would highly suggest getting on as these a very important torque specs.......as well as many others required for engine building.
