Sierra Track Car
« on: May 18, 2010, 09:52:22 AM »
Hi everyone,

I've been a Capri man for years and after I've seeing what a 24v can do with the right gearing and diff, I went in search of a Sierra with the view of building a fairly decent track car.
 

I am currently looking at an H reg Xr4i 4x4 5dr with a 24v fitted. It has a cage and bucket seats fitted, not sure if it has an LSD, etc etc, so it‚‚žÂs pretty much ready as it is only its running 4WD.

I'm just looking for some advice please

(1) I have a MT75 RWD gearbox from a Capri project, as i want to convert the 4x4 to RWD for some drift days as well. I just wanted to know if I fit this to the Sierra will the prop shaft & other parts need to be changed
 
2) I am aware that 4WD and 2WD struts are different. And then Cosworths are again different.  

Questions: Are some bits of XR4i 4x4 suspension and Cosworths either 2WD or 4WD the same? Can  the XR4I 4x4‚‚žÂs rear suspension transfered onto 2WD shells
 

The reason I ask, is that I have plans to fit adjustable tca, compression struts and adjustable suspension to this XR4 4x4. But down the road I plan to reshell the 5dr with a 4dr or 3dr shell but I don‚‚žÂt want to have spent a load of cash on additional suspension parts only to find out that they won‚‚žÂt fit a 4dr or 3dr shell.

 

Sorry for all the questions but I just wanted to gain some knowledge before I get the 4x4.

You`ll need a prop and possibly the gearbox craddle from a 2wd 2.0l DOHC sierra for when you convert it to RWD as the 4x4 prop flange on the gearbox end is not compatible with the rwd MT75 box.

Regarding the struts my donor sierra for my mk3 escort was a 2.0l twincam GLX but I bought 2wd cosworth gaz coilovers and the fronts went on fine, the rears needed spacing out abit on the lower rear arms and the smurf was needed for some inner bodywork clearance. Cant remember for the life of me what the actual difference between the 2wd/4x4/cosworth stuff is. There was a post containing alot of the info you`re after, I`ll have a look and see if I can find it for you.

Aren't the 4wd shocks thicker then the 2wd's?

4wd's are the same diametre as the Granada ones but are shorter.

Correct.

I have 2wd coilovers with a spacer shim to fit 4wd hubs.

Cheers for the Information Lads.

We bought the car last night and we hope to collect it on Saturday.... I also hope to be getting a 1990 2WD Sierra as a donour vehicle as well.

Not sure what engine is in it....

Would a 1.6 Sierra have a MT75 box with the craddle that I need as well

CVH or pinto powered sierra`s will probably have type 9`s think it was only the later 2.0 twin cams that had MT75`s
