There are two gearbox types fitted to the S and SX. One is a derivative of the 899 box and can be identified because the inner driveshaft seal actually mounts to the differential body. This is known as the wet shaft box as the tripod joint is lubricated by gearbox oil. The other dry shaft box is identical to the Sporting -- theres what appears to be a metal cylinder between the inner CV joint and the
Theyre a bolt for bolt replacement but the Mk2 ratio set is diffrent I got the impression that 4th & 5th are a little taller on the Mk2 box.
AFAIK theyre identical except on the Mk2 Abarths (which have lower overall gearing). The ratios will be out there somewhee on the Interweb if not here.
They cant be identical the rpm drop between 3rd & 4th then 4th & 5th is different going up the box between the Mk1 & Mk2 Seis. The Mk2 gears seem to be further apart at the top of the box hence my feeling 4th & 5th are higher.

Dont get you. Hes asking about Mk1 and Mk2 sporting boxes youre putting up ratios from a 6 speed box Why on earth would they change it
Yes. Just do it.
Some boxes arent interchangeable - I went through this a few years ago. The gearbox mounting points on some dont line up (the centos have two different mounting brackets - Im guessing Puntos do as well). Had one that wouldnt line up properly on the bell housing to the block either but that was easily fixed by swapping the bell housing. The third box proved to be the right one for fit (the vendor was
AFAIK all 1108 boxes will mate with the engine. 899 boxes simply wont. The 899 was not a FIRE engine. BUT some 1108 Seis (and I was forgetting this) came with what seem to be 899 gearboxes with a different belhousing (to fit the FIRE engine). These have wet inner driveshaft joints and -- assuming that all Puntos have dry inner joints obviously wont do the job. You may find that given dry inner CV joints

My 1.1 Punto needs a new gearbox asap I have found a box from a 1.1 Seicento that is local and at a good price. Ive had a search on here but cant seem to find anything properly conclusive as to what Im after. Question is can I go ahead and buy it
a sei 1.1 gear box wieghs 33kilograms according to the fiat cd so it wont be much heavier for a 1.2 HTH James www.clubcento.co.uk httpmyseicento.mysite.freeserve.com
I gotta 4-2-1 mani for a 8v for sale In the classifieds Shims will need to be measured up and the maths doing to get the right shims Boxes are purely down to what you want longer gearing is found in the 1.2 8v puntos and shorter ones can be had from the mk1&mk2 punto sporting 6speed boxes they all need a little modification but all are fairly straightforward Induction your best bet by far is finding a second hand gsr induction with a bmc cda airfilterbox

punto 75 TB is 38mmi used to have one before I replaced it with my 40mm tricker. u can fit one to a spi engine if u swop the mpi top for the spi topthey fit together spot on. tbh looking at the 2 side by side there hardly any difference. hope this helps
thanks for the info. does changing the tb to 38 mess with any fuel to air settings does anyone know
Punto box is the same physically as a cento box although the ratios are different. The clutch operation of a Punto is hydraulic the cento cable. So change over the clutch arm to a cento arm to work with the clutch cable. Cheers SPD

They tend to be a lot quieter with lubricant in them.
They leak past the driveshaft gaiters however if the car is an 899 then either a Sei or Cinq 899 box will fit. Cheers D

Cheers...I owe a beer Id think..
Tom I may have a spare box aftrer tomorrow if you fancy it
Hmm...cost dependant esp if this rebuild doesnt go to plan....possibly Ill let you know
6 speed it the same as the 5 speed and 4500 to 5000K rpm in both of them is 90 to 100mph which of course is against the law Best best is 14 wheels and the gearbag and diff from a Sei Suite
Certainly with the Mk2 Sei the non-Abarth 5th gear is taller than the 6 speeds 6th. It makes about 200rpm difference around the 60mph mark iirc.
I think Alan is referencing the normal Sei box the (Sei Suite) - the final in the sporting and the normal Sei are different as are most of the intermediate ratios. The Suites 5th with its final is way too tall for a standard engine the suites 4th overall gearing is close to the sporting 5th... Noel
sei abarth box As they are suited to the standard 14 wheels Ming
