Apart from the obvious aftermarket bellhousings, are there any rear wheel drive gearboxes that will bolt up to the Duratec?

Thanks

I believe there is a mx5 that came out with the duratec.

Yeah that is correct. The Duratec is a mazda motor.

Pity the ratios are crap on the five speed box.
C/R gearsets are way too pricey, might as well stick with the t9.

I have some 2.98 first gear conversions coming for the T9 that at least give you a better first.
New layshaft and input shaft only. Price TBA dependant on what Customs charge me.
If you have cuppla big ones I can do a complete syncro box with a 2.48 first

The 6 speed delivered in local MX5's is heavy, bulky and not real nice. The Japanese MX5 5 speed fitted to the Duratec in JDM models is worth looking at. MXplus usually have a few - not cheap but. But might fit an auto tunnel.

Depending on what you intend to do with the motor, the type 9 has limited reliability behind a tricked Duratec with decent torque. Clubbie 7 guys chew thru even the h/d type 9 boxes -remember they only weigh 5-600kg as well hence much less strain than in an Escort!

Reckon you are better off sourcing a gearbox of your choice and assoc bellhousing - just my 2.2c worth. The Carrol housing and RX7 turbo box is a nice combo. Will be hard pressed to break one of these. And they fit even in a manual tunnel with a little bit of reshaping.

edit: meant to add, suspect the latter option might be cheaper than the MX5 or Type 9 options.

Had thought about the rx7 gbox, but as this wil be in a rally car I really want a c/r s/c gearset with a 2.39 or there abouts 1st gear.
The price of a gearset for a t9 is much more affordable than anything I could find for the rx7 box.

I am happy to stand corrected though :-)

I understand the RX7 box is used fairly extensively in rallying -possibly because they are so strong. The RX7 s4/5 box out of the turbo rotary is the pick - webbed casing etc. Albins sell the CR gears - not sure $$ but I know they replace 5th with first, first becomes second etc and 4th becomes 5th and is retained as 1:1. Sounds odd but apprently works quite well.

After seeing what a Duratec can do to a HD type 9 in a light 500kg clubbie I suspect you might not want one in a rally car - but could be wrong.

Again Roger Carroll in Adel has quite a bit of experence with this box and mating it to a fairly worked Duratec engine. He also knows the Rocket and Type 9 boxes quite well and hence could give you a very informed opinion.

The albins gear is very good, but at $5330.00 for a gearset......OMG!!!. I could nearly buy a sequential box.

Tran-x have a c/r s/c gearset for a t9 for about 700 pounds.
This seems to be a more viable road to go down to me.

Thanks

Fair enough.

In that case can I interest you in a Type 9 with a CR complete with straight cut Quaife gear set. I am fairly certain it as a 2.7 first. The gearbox was recently totally rebuilt. Also comes with a new quick shift.

Titan bell housing to mate to the Duratec plus a dry sump which bolts to the titan - you will need this is you are looking to fit around the Escort cross member.

Other than mock building, all the items are new/unused.

Decided to go down a different route with a clubbie build hence why no further need.

Can't seem to send a PM so if you are interested perhaps call me mbl 0402 797 870. Ian
