was wonderin...

anyone know the reason Automatic turbo DSMs have smaller injectors and a smaller turbo? I have my own speculation on why but im not sure if i am right. Shed some light on me please

[Midnight_Outlaw]

So that is why they make less horse power! i always wondered why the auto eclipse turbos made less power.

[96TSi]

they only make like 5 less hp

??? smaller turbo? what size turbo is in the auto eclipses? 2g or 1g, i never heard this one b4

[JoeWagon]

2g autos have the same size injectors if I'm not mistaken. Who knows WHY it is on 1g autos, but it's a 13g turbo.

yes 2nd gens, manual and auto have the same size injectors and turbo... and for the 1st gen, i'm bored so i'll research on it cause i dont know why either!

[EclipseRST]

a couple minutes of research and i found it on www.vfaq.com ~ from what i gathered from this info is that the reason they use smaller injectors, turbo, and different cams is to produce more low end torque since the auto trannys suck for torque compared to a manual tranny... heres the info:


What are the differences between a automatic tranny car and a manual tranny car?
For 1Gs, there are several differences between manual and auto cars of the same year, aside from (duh) the transmission.

Auto 1G cars have
- smaller turbochargers
- smaller injectors (390cc)
- a 'power/economy' switch located next to the shift lever
- ECUs designed for the smaller injectors
- cams designed to produce more low-end torque [1G only]

Manual 1G cars have:
- bigger turbochargers
- larger injectors (450cc)
- a nifty little coin holder next to the shift lever, a fave place to put electronic widgets of one sort or another.
- ECUs designed for the larger injectors
- ECUs designed to produce less low-end torque [1G only]

2G owners rejoice, as their auto and manual cars have identical engines - assuming, of course, you are comparing apples to apples. Aside from the presence/absence of the 'power/economy' switch, there are no other obvious differences. There still may be additional differences for both 1G and 2G cars.
