hi everyone I have a 1800xr2i but this month im doing the 2.0 zetec conversion but im gona change my gearbox as my current one feels a like its gona break very soon! so im thinking could I use a 1.1box? for quick acceleration? I know this may not be that straong and my top end will be poor but id much rather have a quick 0-60 time than boast stupid speeds on the motorway! So if you experts have anyhelp or suggestion or even comments let me know all help is appreciated many thanks

use the same one thats already in there. a 1.1/ 1.3 box will blow at the slightest hint of 130bhp. the 1.6si gearbox can barly cope either, so stick with your surrent one and the ratios should be more than fast enough

I would say stick with a 1.8 Zetec gearbox also.

I use an Orion 1.8 LX one (which I reckon must be pretty similar to the XR2i 16v and RS1800 gearbox) and in my opinion it's perfect for a Zetec engine. I've been out in a couple with 1.6 Si gearboxes and they're just TOO short to be enjoyable.

Orions are abit longer than the rs boxes I am led to believe.

You can use a 1.1 box, i have seen it used a few times and still working after a year, depends how hard you drive.

although you want good acceleration, the 2.0 has a lot of power and even with the 1.6 si box, the ratios seem abit too close.

It may well be the case, but it's a lovely gearbox nonetheless

[lucasdemoley]

Soz to hijac but smo how much did you pay for your box? I heard your at 3000rpm doing 90mph?

One of my friends is putting in a lsd into an orion box and using it on his fiesta.

How much did you pay for your box?

[Smo]

Came with the engine I'm afraid, which I paid £75 for in total.

Not sure what speeds at what RPM... I only know naughty speeds possible in certain gears

Next time I'm somewhere that conditions allow, I shall find out for you

cheers dude

I put on my 2.0l Zetec, 1.8 Turbo Diesel gearbox from old Ford Escort... it have a lager and stronger differential and everything is bigger and stronger and i also hope to longer gear ratio.

I use 1.8 Diesel box ('89 Escort) on my ZT. It's has quite longer gear ratio than my previous 1.4 CFI box -> now 2600 RPM @ 100 km/h., 5-th gear. 1-st and 2-nd are short like old one. 0-100 km/h = 7,2 sec. (it's Orion not Fiesta, 1110 kg. without driver)

I'm running an 1100 box however mine is the later IB5 type. It is solid as a rock and can deal with the power, it has been said on here before that the BC 1100 box cannot because of the smaller bearings it uses.

I replaced the Si box for the 1100 one to lower the engine speed for motorway driving. If you are looking for acceleration go for the Si box but you will eventually get p!ssed off with it cause at 4000 rpm it will only be doing 84mph.

Your best bet is to go for a long ratio zetec box or the diesel. The 2.0 has more than enough torque to pull the diesel box ratios with hardly any difference in acceleration over the Si's short ratio zetec box.

for my 2.0 si conversion i'm getting a escort rs turbo box with lsd it should cope with the power fine as rst's r built with that sort of grunt neway

[taylor5788]

of course the S2 ERST LSD box is the right way to go

[gatman]

I running a 1.8 deisel box in my 1.8 16v zetec, and 1st and 2nd are pretty short but 3rd gear is nice and long and u get a good top end with it

Although mine is now starting to whine a bit so wil look into something else when it finally lets go!

[crazycage]

for acceleration you want a s1 gear box and its got an lsd they top out @135 on 15s@6500
