Lotus Europa Bastard from Germany

[ralf]

The adjusting with Tunerstudio is quiet easy. You get a chart where you type in the AFR you want to get.
The you run the car and press autotune. Pressing save it saves the injectiontime in another table.
When I finished the modification the I tested the accelaration of the Celica with a QStarz GPS.
The accelaration from 0-100km/h changes from 10seconds to 8,5seconds.

After driving 13.000km with this engine in the Celica it was removed to get installed in my Europa.
The block was sprayed in the same grey like the chassis. A aluminium oilpan was installed.
This pan has the oilstick at the right rear position, so it is easy to check the oil level in the Europa.

To mount the 4AGE engine to the transmission I used a adapterplate made by Mr. Pels.
This plate is a very acurate part. However to fit it I the Spider chassis some adjustments has to made.

The Toyota flywheels weight was reduced from 7.04kg to 5.81kg. A Renault (Fuego, R18, R20) 200mm clutchdisk was used.
The pressureplate from SACHS TYPE MF200 made for an Opel was used to make a hydraulic clutch conversion.
The the flywheel and ressureplate were balanced.

A heavy modified central slave cylinder from the Opel Adam was used. The bellhousing was modified to hold the cylinder.

A Quaife LSD Type QDF2X/7 (for Lotus Europa 4sp 336) was installed in my Renault 395 5speed transmission.
To install it some modifications at the inner driveshafts dand the seals were required.

[ralf]

To mount the engine in the Spyder chassis I used couplings of a Jaguar XK (similar like used in the Seven S1).
Two inner and two outer brackets where made to install them. The outer brackets get powder coated, the inner zinc plated.

[ralf]

To install the transmission in the chassis a Spyder 395 carrier, which get a grey powder coat was used.

In my opinion the original design of the transmission linkage is not good.
I made a different design which might be better.

[ralf]

I don't find an exhaust manifold for an 4AGE in an Europa. But in UK I found a flange for the 4AGE that I used to make a manifold.
I also found manifold of a Ferrari 328 which looks like it can be used to make my own manifold.
The 4to2 area of this manifold fits realy good for my project

[ralf]

The rest of the exhaust was made my standart parts welded together. I use two 2 1/2inch silencer, after the first I can open a valve
to release the exhaust straight out.

[ralf]

After 13.000km driving the 272° inlet camshaft shows some wear. I was replaced by a 292° with only 7,5 lift by Fritzinger.
To make the engine look like a Lotus TC a aluminium Valve cover was fited and the mounting for the distributor was cut away.
The alternator of a Citroen 2CV was placed at the bellhousing and driven by a pulley mounted to the exhaust camshaft.
There are two posts how the valve cover and the pulleydrive were made in 'Garage' ('BigValve style valve cover for TOYOTA 4AGE 16V engine' and '    
alt pulley modification for TOYOTA 4AGE')
