Hi guys!

I been lookin in the forum and on google, and no luck as of yet. I just need to confirm the specifics on two 3sge's i have, in regards to what they came out of (celica or mr2), and what exact year.

How do i go about reading these 7 digit engine numbers?

1) 3s 0300058

2) 3s 1304547

regards and thanks in advance,

I have no goddamn clue.

BUT.. i'm sure if you post pictures up here, someone can quickly identify the gen of the engine, and give you all the information.

Ah yup! cheers mate. Yea i know what Gen they are... but just was curious on specifics. Cause some parts listings were different for early gen 2s as apposed to later gen 2 ge's etc. etc.

You'd be surprised though.

I have a gen4 3sgte, however I'm using some parts off the gen1 3sgte (harmonic balancer). While part numbers may not match up, the parts are the same sometimes.

From Wikipedia....

Gen 1

First generation 3S-GE was produced from 1986 to 1989, arriving in both Northern American versions, as well as In Japan as a second variation. The Northern American engine was slightly less powerful, producing around 135 bhp (101 kW). This engine was the only Gen 1 3S-GE to come to North America, in the Celica GT-S (ST162). Among other things, the JDM version sported a more aggressive ECU and lacked the EGR valve system, pushing the output to somewhere around 150 bhp (112 kW) and 129 ft·lbf (175 Nm) of torque.
[edit] Gen 2

The second generation was produced from 1990 to 1993, receiving a slight boost in output to 113 kW (154 PS). Peak torque went to 137 ft·lbf (186 N·m). It also proved to be a slightly more reliable engine. The second generation also did-away with the T-VIS system, which was replaced by the ACIS (Acoustic Control Induction System), proving to be much more efficient. T-VIS was, however, retained on the second-generation 3S-GE's turbocharged counterpart (3S-GTE).
[edit] Gen 3

The third generation 3S-GE was produced from 1994 to 1999. Power output was increased to 177 bhp (132 kW, 180 PS) over the gen 2, while torque figures stayed the same. Non JDM 3S-GE motors received a minor revision in 1996 for emissions (EGR) which reduced power output to 173 bhp (125 kW, 170 PS) @ 7000 rpm.
[edit] Gen 4
BEAMS 3S-GE 4th generation engine ("Black Top")

The fourth generation 3S-GE, also known as the BEAMS 3S-GE began production in 1997. The first version was equipped with VVT-i and produced 197 bhp (147 kW, 200 PS) @ 7000 rpm. It was available in a few models sold only in Japan - the MR2 G and G-Limited, the Celica ST202 SS-II and SS-III and the Caldina. BEAMS is an acronym which stands for Breakthrough Engine with Advanced Mechanism System.

In 1998 a second version was released with dual VVT-i (variable timing on both the intake and exhaust cams), titanium valves, battery-backed injectors and a slightly higher compression ratio (11:1 instead of 10.5:1). This engine powered the Altezza RS200 and produced around 207 bhp (154 kW, 210 PS) @ 7600 rpm.

The two variants are easily identifiable by colour. The cam covers on the earlier model are red and on the later model, black. They are often referred to as the "Red Top" and the "Black Top" respectively.

The "Grey Top" BEAMS 3S-GE was an available engine option in the Rav4 and Caldina GT in Japan. Even though the valve cover on this engine is black, it is referred to as "Grey Top" due to the grey intake plenum to differentiate it from the Dual-VVTi "Black Top" in the Altezza. Power output is 177 bhp (132 kW, 180 PS) @ 6600 rpm.
[edit] Specifications

These are common to all 3S-G engines except for the BEAMS 3S-GE, which has a narrower valve angle.
Capacity 1,998 cc (121.93 cu in)
Bore x Stroke 86 mm (3.39 in) x 86 mm (3.39 in)
Intake Valve Diameter 33.5 mm (1.32 in)
Exhaust Valve Diameter 29.0 mm (1.14 in)
Included Valve Angle 44.5 °
