N/A vs. Turbo gearbox identification

[PaddyDoyle]

How do you tell the difference of a NA vs.Turbo gearbox without splitting it or checking the chasis code? I heard something about the casting line going along the selector?

I think most ep91 na boxes have a black metal 5th gear casing whereas turbos tend to have an ally one.

as far as im aware theres and extra lug or bolt hole that's threaded near the gearbox reverse switch if ya look at these two pics you can see it afaik these are glanza gearboxes

and without are N/A gearboxes

yeah that's what i've been told a while back too

The na centre section of the gearbox is nearly an inch shorter as they have thinner gears

just whey them turbo boxes are heavy na boxes can be picked up with 1 hand there very light

i ran an n/a box on my turbo with 200 bhp for nearly three years daily and its still going to this day.
