The 3SGE and 3SGTE are
important engines in the Toyota line-up. It is the most potent of all the Toyota 4 cylinder engines in
the important 2000cc class. Celica,
Camry, MR2, RAV4, and Corolla owners can benefit by upgrading to this engine.
For Celicas, Camrys, MR2s,
and RAV4s- equipped with the 3S, 3SFE, 5SFE- engines the natural upgrade is the
3SGTE with horsepower ranging from 200 to 245 HP in the different generations.
With minor bolt-on upgrades power up to 300 is attainable. Internally-built engines can produce up to 350 safely.
The standard transmissions can be used, but be aware that you are running
a lot more horsepower.
For a milder set-up the
3SGE may be adequate. Naturally
aspirated the 3SGE is available from 140 to 210 HP.
The 2nd generation (never imported to the US) produces 170 HP
and relatively cheap. This has
compatibility with parts from the US engines, and is therefore easier to get
parts for. The 3rd generation has 200 HP, and we support
parts for this engine. The 4th
generation with VVTi has 210 HP, but is very expensive.
With such a wide choice of
engines, it is more the budget rather than HP availability that will determine
your choice. Converting engines
will require changing harness, ECU, AFM, related relays and igniters.
No these are not legal in the US, unless you use US model engines (which
limit you to the 1st generation 3SGE and 3SGTE, in the Celicas, or
the 2nd generation 3SGTE in the MR2s and AllTracs).
Japanese imported engines
do not have EGRs- an important smog device required in US engines.
It is impossible to modify a non-EGR head.
Emission controls in Japan are stricter than the US, so the engines
actually run cleaner, but they will fail any visual smog inspection.
Any S engined Celica is relatively easy to do, if you have all the
correct parts. Celicas with the A
engines will require a new transmission, new engine brackets and new power
steering and ac lines. For turbo, read the following MR2 notes.
Stick with the 2nd generation engines as it has a built-in
Turbo conversions are best done using the 3SGTE, rather than turbo kits.
3SGTEs drop in easily with minor rewiring and the usual new resistors,
igniters, and relays. You need the
correct engine harness, ECU, and AFM. We
normally stock complete conversion kits. Changing
transmissions is not critical, but if you plan very heavy use go get the turbo
transmission. This will require new
axles, depending on the year model of the transmission, ABS, LSD, etc.
The 3SGE is a good substitute to the 5SFE, in fact in Japan it is the
standard normally aspirated engine. For
the ultimate- drop a 3SGTE in an AW11!
The 3SGE and 3SGTE engines have been installed in the FWD and RWD Corolla
models. In RWD configuration, new intake and exhaust manifolds need
to be fabricated or the original units reoriented, since these engines were
originally designed and installed at an angle.
See our list of RWD conversion parts- NOTE this is to fit the 3SGE or
3SGTE into a RWD chassis, not to convert cars to RWD. The only exception is the 4th generation VVTi
engines that came in RWD form only! In
FWD, new brackets for the engine and transmission need to be fabricated.
These are general
guidelines. We have no step-by-step
instructions to do these conversions, since there are a lot of variables
involved. Do not attempt if you are
doing this conversion by yourself and feel you are not up to the task or your
shop has never done one before. See
the 3SGE / 3SGTE TECH NOTES also.
