How does it compare with the trumpets as apposed to the oe airbox?
thanks for the advise guys. would it maybe help if i made a subframe to prevent that happening?
It's much louder :dQuote:

runs a lot smoother when the engine is cold and i think the torque has moved a bit to the lower revs. but thats just my feeling ;)
Just mont them vertically at the front, you might get away with it then. Otherwise you need normal bearings in there like jonlem's kit.Quote:

To the point where I don't like the look of that clevis - especially given you're on 205 width cut slicks with an LSD; I've bent something of a similar thickness on road tires & open diff from cornering. IF you do run them and you find the steering wheel goes out after hard braking / cornering then be aware you've bent one.
When thinking about welding them on, measure the distances VERY carefully as they're designed to allow some scope for greater castor - so the midpoint of adjustment should be similar to o.e length. Also they should be ideally welded on so at rest, they sit parallel with the ground.
A good build overall and I like the approach you have.
Had to get my car ready for the first "test race", therefor i decided to get my car in shape.
After two years the paintjob was a bit worn at the sides.
http://i260.photobucket.com/albums/i.../IMG_6526c.jpg
after fiddling with the paint it was good as new :)
http://i260.photobucket.com/albums/i.../IMG_6530c.jpg
new tires on the front
http://i260.photobucket.com/albums/i.../IMG_6532c.jpg
strapped to the trailer it was ready to face its first race.
http://i260.photobucket.com/albums/i.../IMG_6535c.jpg
Nice sticky tyres...
Raceday :d
The day started unspectacular, first thing to do: find a parking spot.
http://i260.photobucket.com/albums/i.../IMG_6564c.jpg
and get the competition number
http://i260.photobucket.com/albums/i.../IMG_6556c.jpg
through the morning i took a lot of photos and supported a friend of mine while he was driving. So i had enough time to think about what it would be like to drive my own car.... and that made me nervous as f*** lol
12:45 time for the savety check
http://i260.photobucket.com/albums/i.../IMG_6745c.jpg
13:00 time for some action.
1. Training run
No traction, i had no idea how to handle the situation :confused:
It was very confusing, it felt like there was abolutely no grip on the front, i expected way
more than i was presented with.

->onboard video<-
http://i260.photobucket.com/albums/i...CH/video12.jpg
2. training run
No improvement. Was it the tires witch were new and had been barely driven?
Am I doing something wrong? Toe settings wrong? Many questions and no answer.
unfortunately i forgot to turn on the onboard camera
-> outside video<-
http://i260.photobucket.com/albums/i...CH/video13.jpg
Really huge build, i recently built up my track car but mine is a very low spec and cost but, I sympathise with the having to make your own washers etc. I even had to improvise my own wiper mechanism (from a corsa B) to get through an MOT.
I am no expert on steering but I suspect it will be the camber and also without being patronising, as you have changed the track ends and so on, the tracking is probbaly miles out.
Keep going though, a massive and unusual build.
1. Timed run
I was disillusioned, I didn't know where the fault was, I didnt know how much time it took for me to drive the course, but it felt slow.
At least i could drive 3 times so maybe there's potential to improve.
Not again, i forgot to turn on the onboard camera :mad:
I had made a massive mistake and would like to know what happened :wtf:, but i had no video footage. At the end i thought i had figured it out how to drive and was way too fast for the last bend.
Green: OK / Red: my way :d

http://i260.photobucket.com/albums/i...CH/video14.jpg
2. Timed run
I was getting faster, i realised i had to change my driving style. Let off the gas and the car was understeering immediately! So i had to keep my foot on the gas and driving was a lot easier. :)

http://i260.photobucket.com/albums/i...CH/video16.jpg
3. Timed run
Ok, it was obvious, the faul was: me :wall:
Now i knew what was possible with the car. The run was clean and fast, foot to the floor and i was flying, the track became bumpy as hell but the diff was working its magic and in the end i couldn't resist to yell a loud "yeeeeehaaaa" lol

The car always needs to be loaded to make use of it's tyres, so if you accelerate hard towards an apex, brake heavily at the latest point possible, let off a little to turn in... this holds all the weight onto the front end, it's like free downforce for your steering. As you found out acceleration gives a good pull through a bend so that's your next step, accelerate through the apex. The physics of that I've never understood because it should load up the rear and make you understeer like a pig but never does lol
Some wikid videos, loving the position of the camera in the onboard camera!
Impressive driving, sounds awesome!
The CV-Joint track ends aren't mounted to the car and the steering geometry is perfectly set to my desired values ;)Quote:

The purpose of the race had been fulfilled, now i know how to drive with this car. It will surely need another training or two, but now i'm confident.
Here a few pictures.

After the race i went home because i was happy with the knowledge how to drive with the differential.
So the surprise came a few days later when i received an email wich said:
"I got your trophy... would be nice if you would pick it up"
I won a Trophy? That's impossible! :d
Clearly i had to pick it up. I won it because the first third of the field got a tophy and i was 5th of 19! :eek:
http://i260.photobucket.com/albums/i.../IMG_6890c.jpg
Here's the Ranking
http://i260.photobucket.com/albums/i.../IMG_6892c.jpg
Next time i'm not going home until the cup ceremony is over lol
Big thanks to the VW Polo driver (VW 3010) wich took my trophy to give it to me! :thumb:
One week after the race, same place:
Opel Meeting
http://i260.photobucket.com/albums/i.../IMG_7263c.jpg
To the 30th anniversary of the Corsa A (Nova) all Corsas could park side by side.
http://i260.photobucket.com/albums/i.../IMG_7259c.jpg
me among them :)
http://i260.photobucket.com/albums/i.../IMG_7272c.jpg
Was fun to talk to other Corsa onwers and suprise everyone with the fact that i don't have a redtop lol
Lovely! I'd quite like to be there! Excellent result on the diff and a good read. Keep the updates coming. Danke! :-)Quote:

Love the high viewdown, with the black wheels it makes it look like its gliding around...
The coilovers are approx 2cm higher than the road legal minimum, so shouldn't be on the bump stop. The springs are as im aware: 50 n/mm. Not very hard, for sporty road use.Quote:

Hi There!
I've been busy lately and i got some spare time so.. let the writing begin :d
Because you can get in very big trouble for not having a catalytic converter under your car in switzerland (loosing your driving licence and so on) and i wanted to improve the exhaust system i decided to switch to a cheap and hopefully little more effective solution.
I wanted to replace the original cat...
http://i260.photobucket.com/albums/i.../IMG_7364c.jpg
..with a C20XE cat.
http://i260.photobucket.com/albums/i.../IMG_7372c.jpg
Therefore i had to cut the exsiting Manifold in pieces.
http://i260.photobucket.com/albums/i.../IMG_7376c.jpg
some adjustments with the "new" cat.
http://i260.photobucket.com/albums/i.../IMG_7379c.jpg
made a new pipe for mounting after the catalytic converter with a much bigger diameter :cool:
http://i260.photobucket.com/albums/i.../IMG_7382c.jpg
welded everthing that had to be welded and monuted it to the car
http://i260.photobucket.com/albums/i.../IMG_7396c.jpg
http://i260.photobucket.com/albums/i.../IMG_7400c.jpg
unfortunately it didn't make a big difference... at least i tried :roll:
Then i started to make the mountig points for the CV-Joint Suspension.
I tested if it would have been possible to weld the mountings vertically but that wouldn't work because the angle for the tie bars was bigger than it would allow.
...so horizontal it is!
http://i260.photobucket.com/albums/i.../IMG_7421c.jpg
before welding
http://i260.photobucket.com/albums/i.../IMG_7425c.jpg
and after
http://i260.photobucket.com/albums/i.../IMG_7433c.jpg
POR15 for rust protection
http://i260.photobucket.com/albums/i.../IMG_7441c.jpg
Nice
http://i260.photobucket.com/albums/i.../IMG_7437c.jpg
Bought some second hand brake proportioning valves.
http://i260.photobucket.com/albums/i.../IMG_7445c.jpg
and a computer cable lol
http://i260.photobucket.com/albums/i.../IMG_7457c.jpg
After a couple of days i began to disassemble the enginebay..... one more time lol
still complete
http://i260.photobucket.com/albums/i.../IMG_7570c.jpg
Everything had to go... EGR, MAP Sensor, idle valve and so on
http://i260.photobucket.com/albums/i.../IMG_7572c.jpg
including the whole engine management
http://i260.photobucket.com/albums/i.../IMG_7574c.jpg
then had to change the camshafts
http://i260.photobucket.com/albums/i.../IMG_7580c.jpg
to 266° cams
http://i260.photobucket.com/albums/i.../IMG_7585c.jpg
while i was changing the cams i had a visitor from UPS :)
The writing on the parcel was promising

there was a lot to do. every cable had to be connected by myself
http://i260.photobucket.com/albums/i.../IMG_7610c.jpg
in order to fit the ne injectors i had to modify the fuel rail a little bit
top original / bottom modified
http://i260.photobucket.com/albums/i.../IMG_7597c.jpg
with fitted injector loom. Very tight, but it works
http://i260.photobucket.com/albums/i.../IMG_7598c.jpg
had to cut the distance sleeves, because the KMS injectors were a bit shorter than the original injectors
http://i260.photobucket.com/albums/i.../IMG_7595c.jpg
then had to switch the TPS sensor vom passenger to drivers side.

Nice work as always. On the tiebar brackets would you be better boxing the other side in too to match the bent side? I'm no expert but it sounds like it'd add a bit more strength
Hi, good choice with the kms and risse-motorsport and nice corsa. :)
i decided to make my own subframe wich connects the tiebar and tca's to stiffen everything a little bit more.Quote:

thanks... or in a more familiar language: Danke! :d i think it would be better for you to check my thread at corsaforum.de ;)Quote:

KMS is an excellent choice. A guy local to me sells loads of them and uses KMS in his own cars/on his own motorbikes to great effect.
And... it's Dutch! :thumb::thumb::thumb::thumb::thumb::thumb: ;)

@ novasport: Here you go http://www.streetridez.net/index.php...ew&picID=57191
I've been busy over the last few weeks so here are the results of what i was up to. :)
Because the camshaft sensor is no longer needed i grinded the reference points of. This would maybe reduce some mass that otherwise has to be moved..... unlikley i know lol
http://i260.photobucket.com/albums/i.../IMG_7611c.jpg
and mounted
http://i260.photobucket.com/albums/i.../IMG_7615c.jpg
The bracket for the throttle position sensor had to be slightly modified because it wasn't possible to put the plug on the TPS.
http://i260.photobucket.com/albums/i.../IMG_7616c.jpg
problem solved
http://i260.photobucket.com/albums/i.../IMG_7623c.jpg
To get a first impression what needed to be done i layed out some wires including a standard C16SEi loom which i needed to cut apart.
http://i260.photobucket.com/albums/i.../IMG_7625c.jpg
I had to reuse the fuel relay...
http://i260.photobucket.com/albums/i.../IMG_7627c.jpg
...and the connector for connecting to the standard nova loom.
http://i260.photobucket.com/albums/i.../IMG_7628c.jpg
joined them together including a piece of KMS loom
http://i260.photobucket.com/albums/i.../IMG_7629c.jpg
after some fiddling with the loom i managed to lay out the cables
http://i260.photobucket.com/albums/i.../IMG_7630c.jpg
to keep the water, oil, fuel or whatever out of the car i used the plug from the SEi loom.
http://i260.photobucket.com/albums/i.../IMG_7632c.jpg
and after some hours i had the right lenghts for all the cabels.
http://i260.photobucket.com/albums/i.../IMG_7633c.jpg
after that i had to fit the ECU connector, therefore i had to cut all the cables to the same length.
http://i260.photobucket.com/albums/i.../IMG_7638c.jpg
The KMS wiring diagram is very easy to understand (at least for me :tard:) so ist wasn't that difficult to wire everything up.
http://i260.photobucket.com/albums/i.../IMG_7642c.jpg
finished
http://i260.photobucket.com/albums/i.../IMG_7645c.jpg
two 'n half hours later i had myself a nice little engine loom :cool:
http://i260.photobucket.com/albums/i.../IMG_7649c.jpg
I fitted the loom to the engine and put on the ignition.
I was suprised it came already mapped with a mapping for a C20XE
Ignition map
http://i260.photobucket.com/albums/i...CH/KMS-Ign.jpg
Fuel map
http://i260.photobucket.com/albums/i...CH/KMS-Inj.jpg
I made a short system check and everything seemed fine, so i sorted out the little stuff that needed to be done.
for example i had to make a temporary solution to connect the adjustable fuel pressure regulator. not pretty but it works :)
http://i260.photobucket.com/albums/i.../IMG_7650c.jpg
the first try to start the engine failed and shortly afterwards i was forced to take a brake because it began to rain :wtf:
http://i260.photobucket.com/albums/i.../IMG_7653c.jpg
After the brake i began to find the solution to start my engine.
i checked:
ignition -> no fault
injection -> no fault
set the fuel regulator to 2.5 bar -> not the solution
cables -> positive lead for lambdasensor not connected .... shame on me :wall:
http://i260.photobucket.com/albums/i.../IMG_7654c.jpg
but that wasn't the solution... so i searched on. At least i had now a A/F ratio signal
http://i260.photobucket.com/albums/i...KMS-Fehler.jpg
i checked nearly every wire for a fault.
http://i260.photobucket.com/albums/i.../IMG_7655c.jpg
just out of curiosity i thought i might switch the iginition leads 1+4 and 2+3
after a short spin from the starter motor the engine fired and climed to 3000rpm. Unfortunately it began to rain once again. So i packed my stuff and called it a day.
http://i260.photobucket.com/albums/i.../IMG_7658c.jpg
One day after the successful start the skies cleared and i moved on to work on my nova
tided up the engine bay
http://i260.photobucket.com/albums/i.../IMG_7662c.jpg
and made some adjusments on the ecu
http://i260.photobucket.com/albums/i...S-1st-run0.jpg
first start was very rough. the idle was very low for the cold engine
http://i260.photobucket.com/albums/i...S-1st-run1.jpg
i adjusted the idle to get a higher rpm
http://i260.photobucket.com/albums/i.../IMG_7669c.jpg
1700rpm ... a bit high :d
http://i260.photobucket.com/albums/i...S-1st-run2.jpg
As the water temperature climbed up a continuous lowered the idle speed to about 1200rpm
http://www.youtube.com/watch?v=WM9v-wZrgDg
Then i had to calibrate the throttle position sensor.
http://i260.photobucket.com/albums/i...S-1st-run6.jpg
after all adjustemnts in the ecu that had to be done i decided to do the first testdrive. i was a bit nervous as i stepped into the car. As i was on the driveway i nearly put in reverse and parked the car. Luckely i choosed to drive on :)
short stop to make a idle check and grab a picture
http://i260.photobucket.com/albums/i.../IMG_7672c.jpg
over all the first testdrive was a success.
http://i260.photobucket.com/albums/i.../IMG_7675c.jpg
wow simply awesome stuff having a go at that yourself! well done!
Thanks! I'm trying hard to get as much as possible done by myself. I learned alot about the inner workings of the engine just by reading the KMS manual and see the effects it has.
But shortly after that the engine began to behave very strage. After 2 weeks i found the Problem: The brand new KMS Ignition Coil was faulty and managed to mess up my whole mapping.
I replaced it by the original GM Coil which works just as fine.
Therefore i soldered the GM connector to the loom.
http://i260.photobucket.com/albums/i.../IMG_7865c.jpg
Here you can see how much was upset due to the damaged Coil. As it turned out it was a lot more upset then this picture shows. Every red bit is corrected.
http://i260.photobucket.com/albums/i...H/KMS-Map2.jpg
Here the fuel map after some corrections made by the lambdasensor.
http://i260.photobucket.com/albums/i...H/KMS-Map3.jpg
Special thanks to Marcel for his help to find my Problem and supporting me! :thumb:
http://i260.photobucket.com/albums/i.../IMG_7781c.jpg
Then its was time to improve the little things.
For easy access to the ecu, i made a hole where i could connect the lead permanently to the ecu.
http://i260.photobucket.com/albums/i.../IMG_7876c.jpg
The lead ends now in the glove compartment for easy plug and play.
http://i260.photobucket.com/albums/i.../IMG_7879c.jpg
And i made a custom shiftlight by myself.
4 LED's an a 270 ohm resistor soldered together
http://i260.photobucket.com/albums/i.../IMG_7888c.jpg
drilled 4 holes for the LED's in to the speedo cover.
http://i260.photobucket.com/albums/i.../IMG_7890c.jpg
perfect :cool:
http://i260.photobucket.com/albums/i.../IMG_7894c.jpg
The first test for the Shiftlight was made with the throttle position sensor. When the Sensor passed the value "10" the light had to go on.
http://i260.photobucket.com/albums/i...Shiftlight.jpg
aaaand it works!
http://www.youtube.com/watch?v=BAwX4NeRnsE

What front strut brace is that you are using?
That's a Wiechers strut brace, as it is the rear strut brace.
My friend linked one of your Nordschleife video today. I really like to watch this again! :)
