difference in 4g63 from auto than 5spd?

[Ghost_GSX]

Are there any differences in the cams, injectors, etc. in a 2g 4g63 from an auto than one out of a 5spd?

No, the differences are in a 1g auto-5speed.

Thats incorrect. A 1g auto has 390cc injectors vs 450cc injectors on the 5 speed. The ecu is also different. A 2g auto and 2g 5speed both have the same injectors and the block is exactly the same.

I do believe that is what kimba was stating. dont forget the cams and turbo. The ecu's are the same amongst 5-speed and autos.

Aight. Just making sure.

i knew there was a difference in the 1gs, but i just wanted to make sure on the 2gs
thanks for the help

1g fuel pressure regulators are different from the auto to 5-speed. I had to change mine out when I added 450 injectors and manual ecu. Different flow rates.

As far as the 2g is concerned,just the auto and 5-speed are the differences as has already been stated.

1G autos came with 390cc injectors and the 13G turbo stock. They had 180hp from the factory. Other than that and a higher fuel pressure(42psi?) from a different fuel pressure regulator, everything else is the same engine wise. With a 14B, and 450s, an auto will be about the same, speed wise.

And yeah, the 2gs I think are the same, engine wise when it comes to auto vs. manual. Both have T25 and same injectors.
