having run about 200hp for the past year my gearbox has had enough. its developed a whine in 4th/5th and ive already got another box lined up dirt cheap. I was gonna rebuild this box then swap em over but am I pissing in the wind? what other options are there for a gearbox to cope with 200hp ish. I know its hit n miss but im led to believe an ib5 is marginally better. or will a fresh bc box be ok at my power. and would any one on here be willing to fit it? cheers matt

Get hold of karlos g

He will build a box with a mk6 casing with later ka internals and a LSD from your broken box, he has the same combination on his 300bhp zetec turbo

Otherwise it's a cts stage 2 at £1295

As Mark says that's the best option unless you want to spend big money on a CTS box which is the same but with a Quaife LSD.

I thought someone on here built boxes, thanks. how much we talking karlos?

£100 max for a mk6 escort box
Your diff
About £100 for the ka box
Plus putting together, and you will need to pm karlos about that but it's defo worth it, I'm going the same route once I get my engine running

PM'd mate, you'll also need a set of diff bearings which are about £40 from Burtons.

Those prices are way off Mark! lol
Roughly £30-£50 for the van and Ka gearbox's.

Here's a Ka one..

Oh I will have to look again lol

I'm just selling my t34.48 so I can fit a stage 3 t3 and steel rods because I want response over power and with the steel rods I can run high boost like 25psi and I don't have to piss about fabricating anything

I'm defo going same as you for the gearbox

I got a KA gearbox for £35
A fully rebuilt Mk5/6 escort box for £55 so only needed to buy a gasket set.
Then got the mechanic at my local tuner to put it all together for me for £40
and sourced a puma gear linkage for £20
Whole thing came to about £170

Karlos G

£40?! Thats crazy cheap, it's quite a few hours work.

Chopshop85

iTrader: (4)

I know! I had £100 on me and he refused to take anymore.

Seeing as the gearbox place in town wanted near £300

Fair play to the guy!

I need to come learn how to do it because in my hands there's no such thing as "bullet proof" lol

boeb

how do u find gear change with puma shifter..got 1 here was thinking of doing it but was put off after hearing stories about it

luke19790_3

A lot better then the standard crap

haz87

^^ agreed

boeb

was gonna us it on ma track car with s2 box(in a frst)but heard it flaps about as no spring in shifter or something like that lol..

was at rsoc at knocky there in and struggled all day finding gears with ma old standard linkage so deffo need to sort something out..
got one of those rally design ones coming for it...u reckon its worth keeping that for ma s2 and using puma linkage on fez ?

Chopshop85

It's 100 times better than the standard shifter, but I am using it on an ib5.
On a bc box it won't self centre If you knock it out of gear.

boeb

hmm dunno if that would be a pain in the ars..is it one of those things u dont notice until its gone lol

the ib5 box seems to make the car drive better to from my experience but dont ask me how

QplateRST!

How come you use the ka box aswell when I built my ib5 box I used a mk6 non turbo diesel van box and put my quaife diff it it I had great ratios?

Karlos G

iTrader: (4)

ka ratios are almost identical to RST ones, most people don't like diesel ratios as they are so long.

rsmark86

iTrader: (3)

It's getting interesting

Chopshop85

iTrader: (4)

If you want identical ratios to an RST BC box you need a KA 1.3 gearset with puma 1.7 final drive. However, the LSD will need modifying as it has a slightly larger diameter then the Puma's final drive.

So what would be the best compromise for abit of track use and road, without giving bad motorway driving

mattxr3i

Would the IB5 be strong enough for a 1.8 Zetec on ITBs etc puttting out around 190bhp on track?

Just thinking, being NA there wouldn't be as much torque as a turbo

Karlos G

iTrader: (4)

Ka/RST Ratios.
Can't really say mate, they are still a weak box at the end of the day, just not as weak as the old BC...
My old IB5 in the Cabby has been running 250-300bhp for the last two years and hasn't broken, that's using launch control and flat shift with real hard driving... But, that doesn't mean they will all take that sort of abuse.

rsmark86

iTrader: (3)

should be alright in the n/a form because although it has good power the torque is nothing compaired.

aslong as it has a very good clutch and linkage set up should be fine, but another thing to concider is the bc/ib5 box doesnt like to change gear anything above 7500prm
