My Type 9 gearbox
Discussion
Its not just the power but revs too, The type nine will do the job but for how long? I would look also for a box with better ratios( 1st is a waste of time).Mates Duratec westie had a closer ratio'd BGH box with a larger bearing inside somewhere to take the strain.Cost about £600 but a recon box with better ratios which is stronger, means one less thing to think about.

180 bhp is not going to be a problem for this gearbox.
It can cope with torquey 2.9 Sierra 4x4s and so you are hardly going to be taxing it.
The V6 Type 9 boxes were designed to cope with the extra torque with larger, better supported bearings than the standard Type 9.It can cope with torquey 2.9 Sierra 4x4s and so you are hardly going to be taxing it.
In the v6 models they are from they are prone to layshaft bearing collapse,bearings are on the small side 
5th gear makes the box run harder than 4th gear if your lucky this box lasts reasonably well if your not they fail prematurely(not one of Fords beat RWD boxes)but in a light car i cant see you having any problems.

I also spoke with Burton's, one of their chaps has a vast experience with these boxes on cologne V6, his experiences is start dropping the clutch with fairly high revs and you WILL burst open the main casing.
I do quite fancy swapping to a T5 but the bellhousing is silly money.

My TVRS1 has the original type 9 and I fitted a V6 Ford Cosworth Scorpio engine with a few minor mods, which makes 224bhp, and 243lbft of torques. The car weighs 980kgs and has been running for 3 years and many trackdays, without any issues. If I am honest it makes a bit more noise in 4ththan I remember (but then its under a lot more strain), but there`s bugger all sound insulation so its hard to judge. If it does let go one day I think I will go for an uprated type 9 rather than all the hassle fitting the T5.

The good news is that the 2005 to current 4.0L Mustang uses a T5 so the bellhousing is matched to the Cologne engine, however the clutch is hydraulic so if you wanted to go that route you would need to fit a master cylinder.I'll just see how it goes then and hope that I don’t have any problems. Quaife does a Type 9 replacement box that’s called the “Quaife 5-speed synchro in-line RWD 'H' Pattern gearbox”. It looks quite smart, it only weighs 30kg, has the same overall dimensions as the Type 9 and it’s rated at 375bhp. If I have some problems I might see about getting one of these rather then rebuilding the Type 9 or fitting a heavy T5, it is a bit pricey though.
BGH Geartech do uprated Type 9 boxes, and also supply them with different ratios as 1st is often far too low and gives a huge gap to second.

It's a case of how long it will survive - that's all.
Mine had 140bhp/140lbft going through it (4-pot Type 9) for about 90k with no problems. I upped the power/torque to the 180/190 mark and 10k later its starting to while a bit and rattle in neutral.
The "2.8i" box has bigger layshaft bearings which helps things, but 170/180bhp is about the limit for any sort of lonegivity. Trouble is, a s/h box will probably already have 100k on it..
The BGH one is about as good as you'll get (without remortgaging the house to Quaiffe).
I'm going with an MT75 (2.3 Scorpio) on mine (2.0 Zetec turbo) as these boxes will take about 250bhp/lbft all day long. With a Duratec, though, you're stumped on bellhousings (unless its a ST170 lump, in which case its a Zetec...). You could try an MT75c - a bellhousing-less version of the MT75 which takes Type 9 bellhousings..

I have a proper Duratec, not a re-badged Zetec. I have looked at the BGH site and they seem very cost effective. The T5 is going to be strong but I’m bit worried about extra weight. The MT75 would be nice but it’s a bit tricky trying to find one without an integral bellhousing. I will see how it goes but will start to make plans for when my Type 9 starts to whine and rattle.

If its the one I'm thinking of the Quaife Box has improved ratios (i.e. long first). Its a good improvement for the track, but a bit of a pain for driving around the paddock, which I would assume translates into crap driveability.You shouldn't have too many problems with the spec you're talking about, but if you're driving it hard or racing it expect the synchros in 3rd and 4th to not last forever. A few running paddle clutches in my series have had the casings blow, but otherwise Synchros are the only issue i've experienced.
There are several ways to attempt improving this situation, the most reliable I've heard so far is to have coated steel baulk rings. McMillan Motorsport sell these but they're not cheap.
I've got Quaife straight cut internals on my box with standard synchros, as has another driver, and neither of us has had a problem, although its a lower power output than your describing.

Straight cut gears are great for track cars, lousy for road cars.
