The Toyota 1G-FE is a 2.0 L (1,988 cc, 121.3 cu·in) straight-six, four-stroke cycle natural aspirated gasoline engine from the Toyota G-family. The engine was manufactured by Toyota Motor Corporation from 1988 to 2005.
The Toyota 1G-FE engine features a cast-iron cylinder block, aluminum cylinder head with dual belt-driven overhead camshafts (DOHC) and four valves per cylinder (24 in total). The 1G-FE is equipped with an electronic fuel injection system. Cylinder bore and piston stroke are 75.0 mm (2.95 in) and 75.0 mm (2.95 in), respectively. The Compression ratio rating is from 8.0:1 to 10.5:1 depending on the engine modification.
The 1G-FE engine generations:
- 1-st gen: The first generation of the 1G-FE was introducted in 1988. This engine produced 135 PS (99 kW; 133 HP) at 5,600 rpm of maximum horsepower and 176 Nm (17.9 kg·m; 129.9 ft·lb) at 4,400 rpm of peak torque.
- 2-nd gen: In 1996 there was the second generation of this engine. The output power increased to 140 PS (103 KW; 138 HP) at 5,600 rpm and 185 Nm (18.9 kg·m; 136.5 ft·lb) at 4,400 rpm of peak torque.
- 3-rd gen: In 1998 was introducted the 3-rd generation with called the 1G-FE BEAMS. This engine used new pistons and connecting rods. This version is equipped with VVT-i (Variable Valve Timing) system on intake camshaft, ACIS (Acoustic Control Induction System) – variation of a Variable Length Intake Manifold system designed by Toyota and electronic throttle body. The output power of this version is 160 PS (118 KW; 158 HP) at 6,200 rpm and 200 Nm (20.4 kg·m; 147.6 ft·lb) at 4,400 rpm of peak torque.
The breakdown of the engine code is as follows:
- 1 – 1 generation engine
- G – Engine family
- F – Economy narrow-angle DOHC
- E – Multi-Point Fuel Injection

Cylinder block
The Toyota 1G-FE engine has a cast-iron cylinder block, bore is 75.0 mm (2.95 in) and the piston stroke is 75.0 mm (2.95 in). The cylinder block, a monoblock specially cast structure, employs the seven bearing support system. The crankshaft has seven journals.
The pistons are aluminum casting. Each piston is fitted with two compression rings and a single oil ring. The compression ratio rating is from 8.0:1 to 12.5:1.

Cylinder head
The cylinder head is made of a light, strong aluminum alloy with good cooling efficiency. The 1G-FE engine has double camshafts (DOHC) and four valves per cylinder (24 valves in total). From 1998 the engine was equipped with VVT-i (Variable Valve Timing) system on the intake camshaft. Camshafts are made of specially cast steel and are driven by a timing belt. The 1G-FE motor does not have hydraulic lifters, so special valve lifters are used to adjust the valve clearance.

What are the dimensions of the 1G engine? What is the total length, height, and width? How much does the engine weigh without the transmission? Can this engine be mounted transversely?
Hi brad, looking for the same information, did you find it?
Where is the coolant temperature sensor located, its position. I cant find it
Hi can i convert my automatic to manual and where can i buy the flywheel and clutch kit
Try to search in the Japanese scrapyard or you could go to Toyota website at http://www.toyota.worldoemparts.com
Yes you can. I converted mine. Cannibalised an accident damaged Is200. Had to play around with the wiring afterwards to get my speedo and km/l gauge to work
I need to be getting more ideas from you and to get some collections and to get for me some spares and your help
What causes hard start on 1g fe in the morning.
Themp sensor locted behind the ltinator green harnis
OK how do I clean it up or replace
I need parts for this vehicle….
I need to replace crankshaft. Where can I buy one. Please assist
i have a gx81 chaser 1gfe engine thats blown, but have a is200 1gfe sitting in the shed, anyone know if the is200 1gfe can swap into the gx81 1gfe chassis?
Where can I find diagnosing machine good second hand.
Need the pinout Diagram for 1G-FE A/T
I’m having this same problem after my conversion, does it have to do with the wheel sensor ? my speedo and gauge aren’t working after i converted
What causes knocking sound from the cylinder head for a 1g beams 2000 engine.
Man there are a lot of stupid questions in these replys
