How many cranks are in a GM Quad 4 engine?
Our extensive research shows there are actually a total of six different blocks, three cranks, three rods, seven heads, four cam housings, four front covers and three oil pumps used on these engines from 1987 through 1995, and that doesn’t include the changes that were made for the 2.4L engine!

When did the GM Quad 4 become 2.4L?
And, the two holes in the “ears” on the back of the block were no longer drilled; it’s a 24574400 casting. 1996 VIN T – The 2.3L Quad 4 became a 2.4L with a smaller bore and a longer stroke in ’96, so the block was modified again.
How many valves does a GM Quad 4 have?
The Quad 4 had four valves per cylinder, tuned intake and exhaust manifolds, no distributor, no plug wires, lightweight rods and pistons to reduce shaking forces, and a crank with eight counterweights that was designed to reduce noise, vibration and harshness (NVH) and bearing wear.

Which is crank sensor mount does torqhead use?
Large 1X camshaft reluctor provides a high degree of angular accuracy and resolution. Adjustable crank sensor mount provides ability to precisely align the 24x Dual Track crank sensor with the crank reluctor. This design ensures you get a solid signal regardless of engine component choice and tolerances. Set it and forget it!

What kind of oil pump does a GM Quad 4 use?
We have seen them with A76 and B77 cast on the beam. There have been three oil pumps used on the 2.3L Quad 4. The oil pump was bolted to the block and driven by a helical gear on the crank until ’95 when it became part of the balancer assembly and was driven by the secondary balance shaft.
What kind of engine does a Pontiac Quad 4 have?
A SOHC variant of the Quad 4 was intended to replace the Pontiac 2.5 L Tech IV OHV “Iron Duke” engine. Debuting in 1992, this Quad OHC was an eight-valve engine and produced 120 hp (89 kW), 40 hp (30 kW) less than the Quad 4 of the same era. Torque was 140 lb⋅ft (190 N⋅m).
What was the horsepower of the 1993 Quad 4?
The 1991–1992 W41s were rated at 190 hp (142 kW), while the 1993 W41 was rated at 185 hp (138 kW) as a result of the first round of exhaust port size reduction to improve emissions and other changes to the Quad 4 architecture to reduce NVH. The additional 10 hp (7 kW) came from longer duration cams and a different PROM .
How many BHP does a Quad 4 engine have?
Output is 150 bhp (112 kW) and 150 lb⋅ft (203 N⋅m). This was the only Quad 4 produced in 1995. This was known as a transitional year for the engine family.
When did they change the engine on the Quad 4?
The first changes of the Quad 4 to address its NVH were two rounds of exhaust port size reductions, followed by the addition of balance shafts in 1995. Further changes were made for the 1996 model year when the engine’s bore and stroke were changed, and the engine was subsequently redubbed “Twin Cam”.
