Best Gearbox for a 1.6 8V

[OllieKing]

am i right in thinking the GTE had an F13??
can you fit a diesel box to a 1.6? is this any better/worse ??
whats the best set up for a 1.6 track car??

[turbojolt]

Seen threads like this before and everyone seems to think the f13 close ratio box is the best

[mowgli]

for a track car, the f13cr has too tall a diff, i think a 4.18 from the old sr gearbox would be a bit better, but it all depends on what tyre/wheel combo you plan to use.

the f13 diesel box is massively over geared for a track car, but i am basically using one with my 1.6 & it is ok on the road.

[General Baxter]

what you need is a diesel box on a 20xe lmao lol

[OllieKing]

So an f13cr with a 4.18 diff. anyone ever used an F10 or is this impossible/pointless?

[garyc]

The gear sets are the same, the f13 just has a bigger bell housing for the 200mm flywheels found on the higher powered engines.

[OllieKing]

oh i see, will the smaller flywheel fit a 1.6?

[garyc]

I'm not 100% sure but the flywheel will fit but you have to change starter motor too.

[mowgli]

if you have a 1.6, then an f10 will not fit. the f13 bellhousing is bigger, the flywheel is bigger & the starter motor site further out.

F15CR from a Corsa Sport is supposedly the best box.

[Stuart]

I understand there is a Corsa D with the F13CR with a 4.29 FD.... ok its got a hydro clutch but you can easily swap out the casing and diff to a manual clutch box.

[brucer]

im in the dilemma with my gte at the moment what to do. ive got an f10 with the 4.18 FD so could put that in the f13 but i know its going to be revving like made at 70mph on the motorway.

is it possible to swap the 5th gear out of a f13wr(or other box) onto the f13cr cluster?

[mowgli]

you can fit the 5th gear into another cluster, to give a decent economy top gear.

you can fit the innards from an f10 into an f13 for it to fit 1.6

F15 internals in an F13 casing (clutch access plate) with a LSD of your choice.
Personally I think the ratio's & FD are fine for an 8v if using the std gearbox, but if the motor is highly tuned then an altered FD might be beneficial.
