Here is a list dif between Gen2 & Gen3
MAP sensor instead of AFM
- Bosch D-Jetronic (Gen III) vs. L-Jetronic (relatively primitive) engine management
- CT20b turbo replaces CT26
- Boost raised from 10psi to 13psi
- Fuel cut raised from 12 psi to 18 psi
- Different ECU
- 4 wire O2 sensor
- Shim under bucket valve shims
- slightly more aggressive cams
- Revised internals (pistons, con-rods etc.)
- Revised cylinder head cooling passages/water jackets
- Revised intake manifold (8 'independent long ports' reduced to 4)
- Revised gearbox with close ratio gearing
- lower compression ratio
- stainless steel head gasket
- factory 540cc injectors replace 430cc injectors
- revised fuel rail with bigger bore and relocated pressure regulator
- TVIS eliminated
- EGR eliminated
- LSD in 80% of them
- throttle body increased from 55mm to 60mm
- inlet valve lift increased from 8.2 to 8.7
- intake manifold inlet air temperature sensor added
- Less restrictive exhaust elbow
- Aluminum oil pan
- more rigid alloy sump and additional oil baffles
- Factory Catch can
- Better Oil Cooler and relocated oil filter (bottom)
- 4 Channel ABS coupled with Traction Control available
- No. 1 compression ring described as 'stainless steel' instead of just 'steel'. Oil ring is described as 'stainless steel' instead of 'a combination of steel and stainless steel'.

both gen2 and gen 3 have 4 wire oxy sensors, and both run map sensors. only the gen 1 (n/a & turbo), and the gen2 turbo motors run afm's.

thanx heaps guys helps lots but the question is is it worth the change of motor cause i have done mine in the gen 2 i have ems already so all it would be is just an engine swap no half cuts and i have the lsd box too but is it worth getting that motor and how much power will it support without falling over.. or chould i just spend the money on good rods pistons and crank?

MR. 2
I don't know the strength of the gen 3 but I am running a gen 1 in my TA22 and putting out 260 RWKW on 22 psi boost with stock internals and stock gen 1 Group A CT26 .

(not trying to sound like a flame...)
Does it really matter what the pistons are made from?
Or the rods etc?
Based on the first 2 Gen of 3SGTE, I would say we can be confident that these motors are not weak.
I think fuelling/ign/I.C. to suit the boost is your largest concern as far as keeping the motor intact.
What kind of power do you expect or hope for?

Does anyone know if Toyota changed the 3S GTE when they stopped it in the Celica GT4 & put it in the Caldina GT-T?
Most of the ST215 Caldinas are auto so they were detuned from the ST205 Celica

Hi Steve
I could be corrected here but I beg to differ that the 215 in the Caldina was detunned matti's site rates them at 208kw @ 6000rpm motor & the MR2 boys in America rate them as 265hp - 270hp
I currently have one apart and they come with crank trigger individual coil packs ontop of each plug + the cams have had the base circle reduced to 1/3 width and every bit of weight removed
The ct20b hybrid of something has had the exhaust maniflod turbo housing cast as one and is a very nice job for a production engine, dump pipe is pressed sheet metal and nice and large
I have also been told that the cams have 8.9mm lift as apposed to the 205's 8.7mm lift but i am yet to confirim either of these figures
Wasn't the gearbox on them a full tiptronic 5speed / steering wheel paddle set up ??? as didn't get this with the engine so would like to know more about this
thanks

Top engine indeed - hope to shove one into my car after I bust the 4A  In my opinion, makes an SR20 look like a model T ford

The official Toyota figure for the manual ST215 Caldina is 191kW (260ps), while the Jap spec ST205 Celica was on the jap power limit of 208kW (280ps).
The gearboxes available in the Caldina are either 5 speed manual 4wd or 4 speed tipronic (steering wheel buttons) auto.
The Caldina is a bit heavier than a Celica (but not much), & also marketed as a sports wagon rather than an all out performance vehicle, so tuned for more mid range torque than power.
I wanted to get a 210 series Caldina but they're not eligible for grey importing.

Re: 'tiptronic'
I have driven a few Lexus with the 'tiptronic' buttons on the steering wheel.
The consensus from myself and others that I have spoken to seems to be "Try it once and forget it". There is a delay, and the sensation is most comparable to shifting an atm at the floor shifter. It just dosent turn out to be useful in practice.
Are you using a M/T?
