Now in 2010 we do not  have a JBA Factory producing any vehicle that has been evaluated in any articles in the various Kit Car Press magazines or approved by VOSA BIVA testing.

Please note these are the old build pages from 1999 to 2004 when we had a JBA Factory in full production from 1982 that was regularly featured in the Kit Car Press and complied with regulations including passing UK Vosa SVA/BIVA tests and TUV tests in the EU.
A 2004 JBA Engineering Ltd Sports SR kit has passed the new BIVA test in June 2009.

What You Will Need 
Short Exhaust down pipe.
Exhaust "U" clamps Three.
Flexible straps Three.

Re-New
Exhaust Mounting Rubbers/Bobbins
"U" clamps.
Exhaust Flange gasket.

You may already have the short down pipe from the donor Sierra. If not you will have to buy one or obtain one from a local scrap yard, make sure it is sound.
Now you will have to have an exhaust made up. It is made up of three parts, the middle section with the first silencer box, the second section which goes through the Sierra subframe. 
The end section which is the rear silencer. These can be made up by your local exhaust dealer in mild steel, if you want it in stainless steel go to a specialist dealer.

This photo is of my own chassis in 1993. However it shows the small down pipe. 

This photo shows the connection on the modern Sports chassis. You will see in both photos how the second part of the exhaust couples up to the Sierra down pipe. This part contains the front silencer box, it is fitted to the down pipe by a flange coupling.
Notice the brake pipes from the chassis tucked up in the air, until they can be fitted to the servo
 

1993 Chassis Above

The next part is the up and over bended pipe section which goes through the Sierra subframe. It is connected to the middle section by a "U" clamp and another "U" clamp is fitted a short distance up the pipe and connected to the chassis by a flexible strap. This strap needs to be heat resistant. Available from local exhaust depot.

The last part is the rear silencer, which needs to have two metal pieces welded on the top in order for it to fit to the chassis using two flexible straps. The silencer is connected to the pipe by a "U" clamp.
On my own chassis I used two round exhaust bobbins to connect them to a bracket I had welded on the chassis frame.

Radiators 
Various

Re-New
All Radiator hoses and Thermostat.
All Heater hoses.
All Jubilee clips.
Consider Electric Fan.

The radiators recommend by JBA are the Cortina or Escort straight port. These seemed fine on the Cortina based JBA's, but owners have been having difficulty with them over heating, on the Sierra 2 litre models in warm weather, using new Cortina radiators and even with an electric fan fitted.
Many have opted for larger radiators, from Ford Granada, Ford Transit, FX4 Taxi, and Volvo. So have a think about this. 

It is advisable to fit an Electric fan to any radiator. You will have to check the space, either on the engine side or on the front of the radiator between the grill bars, make up brackets to fit the fan/s.
Fans are found in all sizes, single and twin. Available from a variety of cars from your local vehicle dismantler.

In fairness to JBA one of my friends Dave Tennant, who owns a Plus 2 Cortina based Falcon has never had this problem. Throughout half the year his Falcon is busy towing a caravan all over the UK, without any problems whatsoever, and with no electric fan fitted.

These photos show the Cortina radiator Doug fitted to his 2 litre SOHC engine. it suffered from overheating, so he changed it for a Volvo radiator and fitted it after removing the intercooler.

Straight Port means the pipe comes straight out of the radiator, not in an "L" shape or a bended shape.
For example the Fuel filler pipe on the JBA Fuel Tanks are straight port. 

In the photo above Doug has managed to retain the Sierra expansion bottle.

Many water heating problems can be solved using Davies Craig electric water pumps fans and in line boosters. These are manufactured in Victoria, Australia and the UK supplier is Merlin Motorsport.
