Hope it is the right place to aks.

We got this rally puma and we need some fast speed, so then we need the box to be fast/shooter in 2 and 3 gear. Can we clone it whit a spare gearbox from ex fiesta, escort, focus.
Hope to make a std 1 gear and then 2-3 gear faster in gearshift and then std 4 and 5 gear...
Hope that some off you now what i meen.

Got a escort 1.8 BC, focus 1.6 ib5 and a fiesta 1.25 ib5 on stock for spareparts...

Pleas help us. Maybe whit infos on rotations on the gearboxes.

personal prefference mate is that a racing puma ratio box is best, with a really good diff. I can change mine as quick as any other box. ib5 is a really good box. The only thing i do find is that the selector forks can bend some times, so i just carry a loada spares and rebuild every 3 meetings or something. It's quite a simple box. Selecting 5th to realign is a little pain, but straight forward when you know how to do it. Need some decent box oil too, can be a little stiff when selecting in the cold.

Hmm ok, mate. We just feel that we need a bit faster topspeed. We have ELF BLS90 for light trucks whit limit slip. Thats a ok oil. Im not the driver, just the handyman when things blow up, he he.

well box should goto 135 i would of thaught with a bit more power. The wheels need only be 15" even for tarmac, maybe 16"

surpised that's not enough in fwd...

We have put a order at Shawspeed on the SS4 cams and HD con rod bolts. So we hope to get more power and then more speed.... We need a faster car in rally, smile smile....

yea can probably get some serious power from that engine. If you want me to get any bits done lemme know. Can get hardened rods if you want. Shot peening the rods gets you a 3rd extra strength.

[MPMotorsport]

Can you help us whit info on setup on your car? Motor and gear.... Suspentions... Maybe we can buy some parts from you if you have some good parts... smile smile

If you want an FRP 'box, I have new ones at £225 collected, or £275 shipped within the UK.

The 4.25 CWP in the FRP IB5 box is probably might be too long for rallying. You will have to work out rpms / speeds based on the gear / CWP ratios and your top rpm.

There are some gear ratio / speed calculators on the internet if you search for them. There is also a list of gear ratios fore the various IB5 boxes as well if you search.

I wouldn't advise shot peening the standard "powdered metal rods"...

[MPMotorsport]

Ok.news from Denmark. We build a focus 1.6 ib5 whit a escort serie 2 lsd. Hope that it will run ok. Just need to put new bearings in it.

[FlashBastd]

Isn't that quite a long 'box? I know on my parents 1.6 Focus the gearing was much longer than on my standard 1.7 Puma.

[MPMotorsport]

It is build as a test... Mayby it is too long and then we will put the 1700 setup back in the focus box whit cable shift.

I've just done a puma 1.7 engine conversion into a mk5 fiesta for track days. It handles like its on rails, the first 4 gears are no problem for our usual track, but the 5th gear is too long, and we'd prefer something which is more like 4.5 gear rather than full 5th, if you understand what i mean. What gearbox can i fit pretty much straight on without modifications to get that bit of extra acceleration in top gear and retain the pull in the other 4 gears?? thanks

FRP 'box, as other posts.

[s76pilot]

So, bought one of these 'boxes' off Flashbastd yesterday, re-fitted engine yesterday afternoon, got the oil for the gearbox this morning, engine running fine again, but, the gearbox is no good. It won't select 2nd, 4th, or reverse easily, and once it does, it won't de-select! 1,3,5 are all fine.

And before someone says have I got the linkage in the right place, yes I have, but there is just no smooth selection. The gears wont select without the linkage either so we know it's a problem inside the gearbox.

Has anyone else bought one of these boxes and had similar problems? Bit of a pain really as it means the gearbox has to come back out!

Open to suggestions. Cheers

Cheers for the callback William. Appreciate the fast response in helping out. Top Man! Nice that in this day and age there are still people like yourself out there. many thanks.

We have run 2 rallyes whit 1.6 focus gearbox and it is too long. We will build it again whit 1700 gears.
