Cool 2gr-fse VS 2gr-fe, why the power output is different

OK; so I didn't make it even a whole year before it gets on nerves about what people think & how they're wrong. LoL!

Things People think, yet are blatantly wrong about:
  • The 2gr-fse does NOT make power because of its direct injection. It makes economy... Only about 40% of the fuel @ WOT comes from direct injection in the first place. Direct VS modern port (Read any descent import engine of the last 20 years) doesn't have a large power differance between them. It has an economy differance.
  • The compression ratio is the FSE's 11.8:1 VS FE's 10.8:1's.
  • The exhaust cam of the FSE is allowed to spin further into overlap. This shifts the powerband higher, or in the case of vvt, raises the power output.
  • The RWD VS FWD exhaust accounts for the majority of the power. The FE is still using a restrictively piped, T merged, fluted pice of **** for a y-pipe. The RWD's don't have god's greatest stock exhaust, but atleast they start off going the right direction without being choked.
And that's where your power differance comes from. This DOESN'T account that Toyota could easily be using different ratio rockers, and completely different cam profiles on the FSE. Which would account for even more of a power differance.The intake manifolds are also different. Who knows which is "better", but they are different.


Bottom line. Direct injection is not making the power, neither are some super special unknown "trickery" of the FSE.



Wierd misc notes:
  • FSE 399lbs VS FE's 359lbs
  • FSE 7.6qt VS FE's 4.5qt of oil









Finally, for the first time ever on Toyota v6's. The 2gr v6's are open blocks. Talk about a complete EEEEEEEEEEK! for power lovers. Somebody will have to make protector plates to keep the cylinder walls from shifting back & forth at high power levels & destroying the engine.

Interested to know where you got all this info ... but just to add some bits:

If you search the SAE, you will find an article on the 2GR-FSE, showing some internal Toyota documents that DI DOES make power, as well as contribute to economy.

Even the IS350's exhaust itself is restrictive, and word on the street is that it restricts the engine by about 20HP.

LMS exhaust removes the cats and makes it true dual on the IS for 23 hp

Yeah, It's not a realistic argument to say that more efficient fueling wont reslt in more power. Probably not ALL the time but then again we don't use all of our power all the time either.

The reasons for the power difference can range from compression, to exhaust to gearing etc.

But really I don't know why anyones complaining about the 2gr-fe, check THIS out:

So buck up guys. Your low CR makes it easier for you guys to make your own power. Most of us in is350 are looking at you camry drivers to figure out how to lower our CR.

Most of the gain between FSE and FE should be the extra 1.0 of compression ( going to 11.8 from 10.8 cr ). It should show a 4% increase in torque across the board or an additional 11 ft-lb.
