20. Mai 05
This is one of the early pictures of my Lotus Elise. Actually my brother
Andreas is just sitting in there.
It is a laserblue MK1 build and delivered in 1997.
10th of December 1997 was the date where i got the car !
The price was 55.566 DM which equals
28.410 EUR
A real bargain !
The Identification-Nr VIN is
WHD32236
Weight should be around 750kg.
|
|
|
Here you see me driving in the city of Mannheim, where i used to live
until 2004.
Now i have moved to Brühl, only 10Minutes away.
|
 |
| Sideview with the roof mounted. Usually
it is always open ! |
 |
| Rear view with the very small tires in
the dimension 205/50 or 205/45
A Janspeed-exhaust has been added.
|
|
| Too bad, the roof is
closed ! The other car is my "all-day"-car.
As one might guess, i like blue vehicles !
|

 |
|
| My old wheels went
to Ebay for around 600EUR. It had Good Year
Eagle F1 as my last set of tires. I liked them for street use.
In the 1997 Elise the dimensions were:
185/55 R 15
205/50ZR16 |
 |
|
| No, the way the wheels point outward is
NOT normal !
Still the old wheels, but a JRZ-Suspension has been added. |
 |
|
| Well, after having the other suspension
i just HAD TO change the wheels and tires.
Currently Yokohama A048 in 225/45 on the Exige Speedline
Magnesiumwheel are installed.
|
 |
|
| Yes, the wheels are in BLACK. First i
thought it looks ugly, but now i liked it ! |
 |
|
|
Sideview Also the brake-hoses have been swapped against Stahlflex
steel ones and the clutch-hose against an Aeroquip.
The steering
transmission was changed to a more direct one.
|
 |
|
| The current mod is the implantation of
a HONDA K20A Powertrain.
Here is the last picture of my good Rover K engine, which was ripped
out at around 44.000km |

Stack 8130 Display
with Display of Oil-pressure, Oil-Temp., Water Temp, Speed, Odometer, Tank
and Voltage. All with user-programmable alarms.
Also a user-defined shift-flash is installed.
Can be fitted with Air-temperature sensor or laptimer with beacon. |
|
|
|
Here you can see the Stack 8130 prior to its install.
If you also want to measure air-temperature, do not
forget to order the air-temperature sensor.
More info about Stackdsiplays
here |
 |
|
|
here you can see the rearview almost completely ripped apart...
This makes my heart ache :-)
|
|
|
| Here a side view shortly before the
engine is getting out.
You can see the JRZ suspension and you can see the dirt of the years
:-)
|
 |
|
| Left side-view with the ECU already
ripped away. |
 |
|
| 9th of February 2005, the new toelink
has already been installed. |
 |
|
| But even better, there is now somehting
red in the back of my car...
In the blue box you can see the Samco-tubing and fitting for the
cooling-system, etc. |
 |
|
| Side view of the K20A engine. |
 |
|
| Toelink, Stahlflex-brake-tubing and JRZ
suspension together with the good old MMC-brake-disc.
Most likely the brakes will be replaced next. I guess
after some trackdays the MMC are scrap-metal :-) |
 |
|
| Top view on the Honda K20A Powertrain.
Below you can see part- and checklists use by Komo-Tec. |
 |
|
| Here my leather-steering-wheel and the
old instrumentpanel.
And yes, i know that the car is really dirty :-) |
 |
|
| Alex working with the lathe on some
parts. |

working on the telephone |
 |
|
| Here goes my old Rover 1,8l engine...
ON EBAY ;-)
I sold it for 1300 Euro, what a shame, but i hope it will make another
Lotus-driver happy.
|
 |
|
| Looks like a flying spaceship... |
 |
|
| 16th of February:
The first blue SAMCO-tubings for the coolingsystem are beeing installed.
I think the blue is in perfect harmony with the red colour :-).
The SAMCO-Kits can be obtained by ISA-Racing,
the official distributor for Germany.. |
 |
|
| Again you can see the
SAMCO-connection-tubings and the aluminium fittings.
Looks well organised in my opinion. |
 |
|
| On the right side of the pic you can
see the gear-box shift-transmisson. Today it was already possible to
switch between the 6 gear. The rear-gear was not possible due to the
blocking-switch not having power yet.
The gearbox shifts very good ! |
 |
|
| Also the oil-cooler is now getting in
place. The 2 blue fittings are the place where originally the oilfilter
was sitting. This is used now to attach the tubing to go forward to the
oil-cooler. |
 |
|
| Here the tubing is going in and routed
to the front-section. |
 |
|
| And here it comes out again....
I know, the car is NOT CLEANED !
But hey, it is for driving and not a SHOWCAR ! |
 |
|
| The Mocal Oilcooler that is going to be
installed. |
 |
|
| Routing of the hose |
 |
|
| The cooler in the front-section with
tthe tubes attached, but not bolted to the car.
I decided against an oil-cooler at the side of the Mk1 due to the
cooling-performance beeing much better with a big cooler in the front
section. |
 |
|
| Here are the hoses already covered with
a heat-shield and the fittings for the oil-filter-adapter are installed.
Next week the ECU will hopefully be installed and then it is time to:
START THE ENGINE ! |
 |
|
| As ECU Daniel suggested the PRO8 from
DTA.
Here
you can find a wiring example for the Pro8 as PDF.
Instead of buying the serial-cable from DTA, there are multiple DIY
descriptions on the web, like this
The software can be downloaded for free at: the manufacturer
site, where you also have a lot more information about this cool device. |
 |
|
| Screenshot of the
actual mapping |
 |
|
| Now the
exhaust-system and the wheels are attached. Looks like it is getting more
and more ready to run |
 |
|
| The motor is able to
drive the wheels :-) |
 |
|
| The belt for the "powerplant"
is now in place. |
 |
|
| The wiring for the
ECU has been completed. Now the only thing missing is the mapping to get the
engine up and running |
 |
|
| Oh, holy cow, it
seems that not all of the wiring is connected yet ! |
 |
|
| The stack is ready
and fitted with additional LED´s. Ome for
example is to show that you are able to go into reverse gear. The reverse
gear is blocked during normal driving. You have to operate a switch to be
able to go into reverse instead of the 6th gear. |
 |
|
| The original stack looks boring
compared to the Stack 8130 in the carbon fitting. Therefor it has to go on
EBAY :-) |
 |
|
| Engine wired and
already filled with water. The intake part is not ready yet and the spark
plugs are not connected. |
 |
|
| Now the Stackdisplay is in place. Looks
sooooo good ! |
 |
|
| Now illuminated ! Stack changed the
Display-Colour of the central instrument from amber to white-
Looks absolutly beautiful.
The four buttons on the lower left are for rotating the lower display and
also for programming it ! |
 |
|
| The picture is not sharp due to the low
shutter-time. And of course my gas-tank is not able to hold 95 Liter, the
Stack is just not yet calibrated. |
 |
|
| The rear-Clamshell is in place and the
motor now almost complete. |
 |
|
| Alex, who was mainly responsible for
the good work. |
 |
|
| Handmade stainless steel exhaust-system.
Looks perfect !
Not too big, but very effective. |
 |
|
| Another view on the engine. You can see
the injection rail and the nice Komotec-plate on the cylinder-head. |
 |
|
| Now the Oilfilter is in place. |
 |
|
| The small switch under the wipercontrol
is to allow the gearshifter to get into backwards-gear. If you operate it
a red warning-light is siwtched on above the Stack-Display.
This is due to the fact that the rear-gear is in the same position as the
6th-gear. |
 |
|
| Now my Elise is at least VERY close to
the door ! The final electrical stuff is beeing done. |
 |
|
| Wiring and basic
mapping of the
ECU. |
 |
|
| Here you can see the
ECU opened. There are Jumpersettings to determine the types of sensor beeing
used. Most other stuff is software tuneable. |
 |
|
| To check something
at the cam-sensor the engine is opened again. Here you can see the typical
VTEC cam. |
 |
|
| A view on a K20
engine-block. The head to the right does not belong to the Honda. |
 |
|
| Pistons etc. |
 |
|
| This head looks a
bit more like a modern one :-). On the left side
of the picture you can see the crankshaft |
 |
|
| This was during the
night when i picked up the Elise in the Netherlands where on-road mapping
has been done for the ECU |
 |
|
| My VW T4 bus has
done a good job while pulling the trailer, but well, the Elise isn´t to
heavy anyway |
 |
|
| During a sunny day
in March i did my first testdrive. So far 500km
have been put on the engine while testing and optimizing everything.
After the first 1000km the car has to go on the Dyno
for final measurements and smaller adjustments, so i had to put some more
kilometers on it ;-)
The engine is started without any throttle and is
firing immediately. The change from the idle-programm until 3000 is a bit
rough when cold, so there is room for some improvement.
Cold temperature adjustements needs time.... |
 |
|
| This was during a
ride on the german highways while checking and adjusting the speed-display.
1815mm whee circimference was the calculated amount for the
Stack-Display-setting, but with 1900 the speed was more accurate with the
measured GPS-speed.It shows 125km/h when i drove 123..
I changed the shift-light from the factory setting
7000rev/min to 8200 and the rev-limiter was set to 9000 for the moment.
On the dashboard you can see the GPS-navigation i used to
calibrate the speed. |
 |
|
| With show-size 13 in
such a small car you have to be careful about what shoes you wear. Shows
with a rim are dangerous because they can jam under the brake-pedal when
changing from throttle to brake. I wear OMP
cartingshoes here. They are only around 50 Euro. |
 |
|
| 812km already driven.
What looks like idle are 3500rev/min due to the non-linear scale. |
 |
|
| |
If you want to hear the sound and have a look how fast
the engine reacts click here (Video in
WMV-format around 700kB) |
|
| This is the look of
the engine-compartment right now. There will be some optical changes and the
baggage-bin will be in place again, but in general thats it for the moment.
Wait, the alarmsystem has to be put in place and been
activated. |
 |
|
| First time on a
rolling road to get an idea of the output of the first mapping. |
 |
|
| First run on the
Cartec rolling-road. Not bad for an initital mapping, bu the VTEC should be
lowered maybe another 500. This result can not
put in images the smile on my face when driving with the new engine !
|
 |
|
| VTEC now at 5800 |
A 4MB Video in WMV format can be downloaded
here |
|
| During a
driver-training in Hockenheim |
 |
|
| Another view, where
the "water-walls" are obstacles and you have to drive around them on the "slippery-floor".
This shows how much ABS,ESP etc is doing, which is not available in the MK1
:-) |
 |
|
| Here you can see the
shift-light at 8500. It switches on at 8200. |
 |
|
| This is the final of
the Hockenheim GP-Racetrack. I already did 3
trackdays with the new engine. |
 |
|
| |
|
|
|
Soon to be continued ! |
