PaddyDoyle Posted July 7, 2015 Share Posted July 7, 2015 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? Quote Link to post Share on other sites
morgey Posted July 8, 2015 Share Posted July 8, 2015 I think most ep91 na boxes have a black metal 5th gear casing whereas turbos tend to have an ally one. Quote Link to post Share on other sites
JDMfreak Posted July 8, 2015 Share Posted July 8, 2015 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 Quote Link to post Share on other sites
gorganl2000 Posted July 8, 2015 Share Posted July 8, 2015 I think most ep91 na boxes have a black metal 5th gear casing whereas turbos tend to have an ally one. yeah that's what i've been told a while back too Quote Link to post Share on other sites
aleximport25 Posted July 16, 2015 Share Posted July 16, 2015 The na centre section of the gearbox is nearly an inch shorter as they have thinner gears Quote Link to post Share on other sites
5e colin Posted July 16, 2015 Share Posted July 16, 2015 just whey them turbo boxes are heavy na boxes can be picked up with 1 hand there very light Quote Link to post Share on other sites
mikey4410 Posted July 16, 2015 Share Posted July 16, 2015 i ran an n/a box on my turbo with 200 bhp for nearly three years daily and its still going to this day. Quote Link to post Share on other sites
