These series of pictures correlate the evolution of the engine bay from start to it's current design
Engine Bay Gallery
Open Cone direct to Throttle Body
This was the first modification I made to the engine. The induction noise was loud but the massive loss of power was such that it lasted less than a few days before being sold on.
First stainless steel covers
After the disastrous venture with the open cone filter I restricted myself to some cosmetic additions. These included a stainless steel cover for the battery, fuse box, rocker cover and the brake master cylinder. The oil filler cap I modified myself from an alloy version from a Mini combined with the original cap.
First additions to the engine bay
This later view also shows the stainless steel braiding that I fitted to the top radiator hose. It wasn't very successful so I didn't keep it long. I also added a cover to the top of the air intake filter chamber
Cover for brake master
This is a close-up of the stainless steel cover for the brake master cylinder that was made by a friend of mine.
First engine bay detailing
As well as the radiator hose I also covered the air hoses between the inlet chamber and rocker breather in the same stainless steel braiding. This was much more successful. I also detailed the lettering on the rocker cover in the same yellow as the bodywork.
As well as the new induction system I also added an alloy billet front suspension brace. This was more for show but was also surprised how much difference it made to the handling when pushed hard cornering. I also added a stainless steel cover to the coolant filler cap.
The 'bling bug' had now got me and from various sources I managed to get some more covers made as well as making some myself. In this picture there are covers for the cam belt cover, wiper motor, and heat shield. Unfortunately not all the covers worked or fitted.
Here is a picture showing some of the covers seen in the previous picture now fitted. The most obvious is the cam belt cover and heat shield. The first set of yellow SAMCO silicon coolant hoses made were fitted and looked a lot better than the previous braid covered attempt. The rocker cover was a prototype which was a poor fit
New induction hose
I managed to source a yellow induction elbow which I married to a stainless steel pipe. Some chrome conduit has also been added to some of the electrical looms. The black ZR logo on the rocker cover has now been replaced with some gold plated lettering MG ZR. The friend who made me the cover for the brake cylinder then made me another for the coolant header tank
Apiro induction system
I was losing a lot of BHP due to heat-soak. I fitted a carbon fibre filter system and attached an alloy pipe to the original cold air feed. The cam belt cover was replaced with a modified Ford version and a production etched rocker cover was fitted. Stainless steel caps were added to the front suspension strut tops, the washer filler and PAS reservoir along with an alloy dipstick handle.
Filter heat shield
To help with reducing some of the radiated heat and also to add some more 'bling' I fitted a universal stainless steel heat shield to the air filter. The cam belt end plate was also painted to match the car colour along with the battery.
Stainless steel cam plate
I managed to source a stainless steel cam plate cover and embellished the induction chamber with some chrome strips
Close up of cam cover
This is a close up of the stainless steel cam shaft cover. I also began to replace the bolts wherever I could with stainless steel socket headed bolts and washers
The engine was now all show but underneath it was still the original 1.4 it left the factory with. It was given to PTP who breathed some new life into the engine with their R140 conversion. This was now a 1.8 with high lift cam shafts, bigger throttle body, alloy induction system and a full remap. The rusty mounts for the strut brace were repainted in red.
The PTP Conversion made a massive difference to the engine not just in looks with the larger alloy inlet manifold but in performance as well.
The alloy pipe to the carbon fibre air filter housing kept splitting so a properly designed for the car ITG Maxogen CF system was added. This made a huge difference to the looks as well as the performance.
Close-up of the ITG
The ITG Maxogen was designed for the race cars and uses convergent/divergent ducts to change the airflow and pressures through the filter and manifold. Not cheap but worth it.
Close up of the Bling
The engine bay was now starting to look very different and very unique. The 'Embossed' MG logo was made by a friend and are actually a vinyl sticker
Various additions to the lighting effects on the car were also added to the engine bay which included some orange EL wire to the induction pipe elbow and blue EL wire threaded through the strut brace. 2 IceLed GEMS were also attached to the strut brace. A set of HID lights were added with the ballast packs being mounted on brackets behind the PAS reservoir and the rusty radiator brackets painted red.
The blue EL wire on the strut didn't work well so was removed. The orange EL wire was also replaced on the induction pipe with a mix of white and purple. Stainless steel covers were also added to the GEMS and a gold X-Power badge added to the rocker cover
A company called Engine Optics made me a set of glass coolant pipes which were unique at the time
The Engine Optics pipes as well as looking good for shows also allowed the coolant colour, flow and condition to be checked.
Illuminated Engine Optics
It was not long beforeI modified the Engine Optics glass coolant pipes with the addition of some LED lighting effects.
New Radiator and Hoses
The engine always ran a little hot after the PTP conversion so I decided to fit the larger radiator designed for the 160. This meant new hoses as the pipe routing is different. It also meant the loss of the larger Engine Optics pipe. The hoses from SAMCO were not designed for the 160 radiator so some creative modifications were needed!
New Engine Optics
I really missed the larger Engine Optics pipe after the new radiator fit so I managed to get a different designed version. It looks so much better now and I even managed to fit some LED lighting to the pipe as well
As well as modifying the engine the bonnet had the original soundproofing removed and a Dynamat Hoodliner was imported from the USA. This is has several purposes apart from sound dampening. It also reflects the heat keeping the bonnet cool and also reflects the lights from all the effects under the bonnet as well as adding to the 'bling'.
When I installed the HIDs there was nowhere really to mount them tidily. The ballast packs along with a lot of extra wiring, relays and inverters are under the fuse box so to protect them and tidy the area up I made a brushed stainless steel cover with an MG logo I had knocking about
Fuse Cover logo
At one of the many shows I attend, I came across a domed vinyl chrome union flag. I applied it to the fuse box cover and the embossed effect was good enough to fool a few people.
The original suspension strut mounts went rusty so they were painted in red. The trunnion tops had stainless steel covers added and then a holographic MG logo added to finish off the effect
