6 speed conversion

[Grey Haired]

When fitting a V7 6 speed gearbox to a V3 how do you get the speedo to work?

I understand that I need diff to match, front axles, but not rear?

Also do I need clutch to suit ?

What about stater motor?

Slave nad master cylinder

Anything else?

i have a 3.9 STI RA Plate diff, i just brought but found i already have a spare so dont really need it lol, paid 300, will sell for the same if your keen, im in chch, where r you.

THanks will keep in mind

v3 = mechanical sender?

Pull the speedo sender off your old gearbox and put it in the new one. Should fit straight in.

5mt clutch will work, I believe, but you should really use a 6mt one.

You match the starter to the flywheel, which you match to the clutch. Again, I would use all 6mt items.

Clutch slave and master cylinder, nfi, someone else will need to weigh in there.

no change needed for clutch slave and master.

if your in need of a 6 speed clutch I have one and believe I have a flywheel.

but you can use 5 speed gear

Thanks guys

What about axles?

[funkytown]

you DO need the 6mt clutch fork!!! that\'s critical as the 5mt one is the wrong shape and is required whether you go 5 or 6mt clutch.

your front axles will go straight on, but beware that v9 spec c onwards comes with female stubs on the box so you have to convert it to male then your front axles work, kits available or you can get stubs from an auto box i believe.

rear axles depends on what rear diff you use to be honest. straight up a normal r180 6mt rear diff wont work with your factory v3 axles. if you go for the 3.9 r160 rear diff (one for sale on here) and quite hard to get a hold of then your v3 axles are mint. IF you go the v7 diff way, you need to convert your axles / rear hubs / brakes etc all over to r180 as well.

clutch / flywheel / starter / clutch slave all as mentioned above.

3.9 STI RA Plate diff the one Speedfreak is offering in this thread?

[Grey Haired]

ANd just to be clear, beat option is to use 6 speed flywheel, clutch and starter motor but its possible to use 5 speed?

[funkytown]

yes i actually used to own that diff ha..

and yes 6mt is best as you get better clamp on the 6mt one, but totally doable bolt in stuff using 5mt as well. its just a smaller diameter set up is all.

[rex-leggy]

aaa yes the fork missed that out.

imo the r160 would be the easiest. rear r180 axles are hard to find at a reasonable price also

you can always go to a shop in the states called DSS (driveshaft shop) they sell specific axels for r180 rated to stupid horsepower but is not exactly a cheap option.

[funkytown]

ooh and the last thing you need to know OP...

you want the 6mt drive shaft, or you can get one from an Auto GC/GF as the auto (4AET) is the same length shaft as the 6mt one

Thanks Guys

Is a five speed starter motor the same as a six speed one? :-\

If not what the difference?

[gotasuby]

The 5 speed starters foul on the 6 speed flywheels.

boon. If you put the mechanical speedo drive into the gear box that ran an electric meter could end up getting an ecl? or a 5.5k rpm cut out?
