2.0 DOHC 1992 FORD SIERRA
Hi can some one please help me. I am building a GTS locost. The donor car I am using is a 1992 ford sierra 2.0 dohc single carb. The engine has
covered 96000 miles and runs really sweet. It seems to have plenty of power, 110mph and still pulling like a train.
The gearbox fitted to this engine is an mt75 five speed. Can any one tell me if this engine would fit ok, and would it be suitable? What would I need
to do to tune this engine?
Many thanks for taking the time to read this.

Hi
Firstly to warn you the Dohc is not a well liked engine on this forum.
HOWEVER, its what i,m using & is far superior to the pinto in many ways. (lighter, lower c of g, more power, LOTS more torque )
I am not familiar with the GTS chassis, but I can say that it fits into a book chassis with ease.
The only prob. you may have is with the MT75 in the g/ tunnel, it depends how wide it is.
One of the reasons the engine is not liked is a lack of tuning parts.
If you are handy there are several things that you can do to incraese power.
On the carbed engine, change the inlet cam for the inj. one.
Get/make a tubular manifold for the exhaust.
Go & look on the FSOC forum.
This is by far the engine of choice there(over the pinto)There are plenty of DOHC engines on there running from 130ish to 240BHP(turbo).
You will here a lot of things about the heads being the weak point .This is true to a degree but then any engine with an alloy head is prone to
warpage.(K series?)
This is my engine with twin carbs

Have a look on my website:
http://gtslocost.locostsites.co.uk/downloads.htm
In the pdf downloads theres the build manual for the GTS.
The DOHC will fit and GTS make engine mounts for them as well.
Cheers,

The question should not be if you could use the engine because the answer is yes, But would you want to?
For off the shelf tuning, forget it  Any thing you want will need to be custom made. You will be looking at installation costs that match the zetec
or other engines unless you can do the fabrication yourself.
Also look at the cost of doing a simple job such as the head gasket, you are talking big bucks. Don’t get me wrong mine was a great engine in the
sierra with very good torque and around 100 bhp. It was good fun and would be more so in a car half its weight. But having done a bit of homework on
spares and tuning I gave mine away keeping the gearbox.
Imho a 1.6 or 1.8 zetec will give 100-150 bhp for not a huge outlay.
1.6 l Zetec low miles £50
38mm bike carbs £30
Bogg Bro’s manifold and carb work £200ish
Megajolt ecu £100
Would be some of the extra things you would need but will allow a lighter engine with of the shelf tuning when funds allow.
I’m building my own chassis to Gts plans ish and found the engine and box will fit but I shifted the passengers side of the transmission tunnel over
3/4 " to get it further back in the chassis to where I wanted it. The Dohc is a tall engine and you will need to mod the sump and the
alternator as it hangs a long way out.You’re your guy for all things Dohc is Paul Buzz,
All this is just my opinion !

Beaten to it by the man him self. Is it on the road yet Paul ?
I moved the engine and box for two reasons first to get the engine and box back in the chassis and second to allow a better prop line for a live back
axle.
Pic is before mods.

2.0 DOHC 1992 FORD SIERRA
Thank you all for replying to my questions so quickly. It is reassuring to see that the ford 2.0 DOHC/mt75 gearbox is being used in the locost. I have
some question may be paulBuz could help me? How much did you have to cut off the bottom of your sump and was it difficult? How did you get around the
clearance for you alternator? And did you have to move tubes G1 and G2 to mount the engine; did you have to make your own engine mounts/brackets? I
really appreciate all your help.

Hi ady
I had to cut around 1.5" from the bottom of the sump. I then contiued the bottom forward to try & recover some capacity.

The sump was migged with my Clarke mig welder. I can be done it just takes the right settings.
The alternator was a NIGHTMARE!!!
There is very little room left after the steering coloum & inlet manifold.
One of my customers repairs starters & alternators for a living said that an alternator will happily work just as well backwards, so I made the
setup in the pic.

No still not on the road I,m afraid. Its one of the downfalls of building a 'book ' car.
I only get around 4hrs a week to work on my car, so progress is slow
