- 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)
- intake manifold inlet air temperature sensor added. i.e. after turbo and intercooler.
- 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

the factory catch can is more accurately described as an "oil-air separator".....

i think with some added pics and cleaned up info this will be up in the FAQ

Also:
Gen 2 head flows a LOT worse than the gen3, due to terrible ports
Gen 3 'MAY' have an extra tooth on the oil pump.

Thanks to Tristan Hewitt for this info (if I've translated the barrage of information rightly)

The Gen3 oil pump has one less tooth on the drive gear. This means the pump turns at a higher speed in relation to crank speed moving more oil.

[mr2lover]

Does the Gen 1 3sgte have any advantages?

[Jorrs]

its original and therefore the best

[mr2lover]

Hahah If only it works like that.

A suggestion, could you please remove all the references to the auxilary systems? and just concentrate on the engine?

An excellent site comparing generation of engines
http://gtfour.supras.org.nz/3sgte%20table.htm <- engine comparison
http://gtfour.supras.org.nz/head%20variations.htm <- gen2 and gen3 head comparison
http://gtfour.supras.org.nz/st205%20photos.htm <-gen3 (gtfour) engine pictures
http://gtfour.supras.org.nz/Turbo%20photos.htm <- ct20b pictures

i have plenty more where those came from.

ok guys, here are some pics that hopefully help out with this FAQ. if anyone wants some larger pics or measurements let me know and i'll grab them, it may be awhile to i use them hehe.

these are all parts off an ST205 Gen3 3S-GTE, the same one that Cool1 is using

mods, if you want to put this in the faq up top, would it be possible to get the images loaded on the toymods server itself as i dont have that much space. cheers

now for the pics, enjoy
