Gen 3 Vs Gen 4, 3S-GTE Options

[fran]

Hello!!! i read about the diferences, upgrades ++ about 2gen vs 3gen 3S-GTE`s but i didnt read anything about the 4Gen 3S-GTE. Anyones knows the diferences betwen those engines? what parts are the same, what performance parts cant be use on the 4gen?

here are some more differences i keep laying around for such discussions....

-Adjustable cam gear (AEM, Fidanza, HKS, OBX, ATS). Any cam gear kit for 3SGTE will fit.

-XS Power SSAC ST205 manifold/downpipe used with a ST205 turbo will convert the one-piece ST215 manifold/turbo to a nicely upgradeable ST205 Ct20b turbo kit. You can add to this a t3/t4 adaptor and you will be able to use a t3/t4 turbo (like I did on my ST215 swap)

-Pistons, rods, crankshaft are all the same for ST205 and ST215

-The injectors are the same as the ST205 one, so, if there is a 3rd gen fuel system available, it will fit the ST215 too.

-The exhaust camshaft is the same as the ST205 one. So an HKS 264/272 exhaust camshaft will bolt on. For the intake, I don't know if the HKS one would fit. Next year, when money will allow it, I'll buy a HKS264/264 camshaft kit and I'll know if the intake camshaft fit or not.

-You can remove the top ATA intercooler and add a FMIC as easy as any other 3SGTE.

The alternator can be replaced with one from any 5SFE or 3SGTE, along with the a/c compressor and the p/s pump (though the 4th gen p/s pump uses an electronic sending unit for the idle-up).

Bear in mind that the 4th gen injectors are also high-impedance, and no resistor pack is used.
-pistons
-connecting rods
-crankshaft
-exhaust camshaft
-cam gears
-timing belt
-water pump
-Intake manifold (bolt pattern are the same)
-fuel rail and injectors from ST215 are 540cc and top feed, so they have the same output rating as gen3, but they are top feed instead of side-feed(gen3)
-exhaust manifold (same bolt pattern)(but the 4th gen exhaust manifold is casted with the turbine housing)
-MAT sensor (manifold air temp)
-MAP sensor
-crank pulley
-oil pans
-oil pickup system
-knock sensor
-ac compressor
-alternator
