After my car was kinda flooded in autumn I stripped the whole interior.

I got the alternator being rebuilt (didn't do much over 12V and had to recharge my battery every week, also made a nice squeeky noise as if my v-belt was slipping...which it wasnt).

Repaired my rustless batterybox (had a crack in it, probably metal fatigue).
Some of my gray/blue wires melted to other wires... replaced all damaged wires, also replaced the wires from de starter motor and the alternator.
My current is now 13,63 or something like that. Want to make another extra ground wire from the alternator directly to the battery.

Today I made my first drive... drives good

only thing that's important is a new clutch since I've got some play in that

at 5000 rpm the engine dips, probably ignition. Runs bad when started, probably the fuel distributor

and the auxilary air tube on my intake boot... that's a piece of garden hose at the moment

the fuel pump doesn't work sometimes, but I think it's the relay... those thingies are quite expensive and Ive got a jumperthingie to override the relay in the worst case.
when converting to megasquirt I won't need the relay so that's a nice €130 saved.

Fuel gauge flips... varies from nothing to the current level, dependant on what electrical stuff is on.
I think it's a ground problem at the sensor or something. Want to check it out anyway.

So... after a few months of nothing, my car is better then when I bought it, so I'm semi happy.

I didn't want to convert to MS anymore because it's so expensive and the government overhere is trying to f*ck us up.
You'll have to pay by km instead of the usual "road tax" which is nothing for my 25 yr old car.
the only thing I have to pay is the gasoline and insurance (70eur/yr). If those new plans are pushed through, my old car becomes expensive...
But, now it runs again... and I still want to convert

found some nice new K&N filters over in the US, will be 150 euro including shipping... that's not too expensive.

Only things I'll have to buy are a LC1 sensor, EGT sensor, IAT sensor, fuel pressure regulator, and the MS unit itself.
When the MS fuel runs nice, I'll replace the head gasket, or maybe the whole head which will be adjusted to the diameter of my new inlet.
When thats done, Ill run spark too.

So much plans for my 924, so little money and time

anyway.. this thread is to tell everyone that I'm happy it runs again

Hey..good to hear that your car is runing again!

its the blue one..right?

I can put you in contact with a guy who can sell you K&N filters for a lot cheaper...i payed 65 EUR for a 924 KN filter.

If the car is runing rough thats not necesarly the distributor...chech the plugs the injectors the WUR the AAV....lots of things..check the fuel pump relay..check everything before you start throwing money. Good luck !

Is this the CO value at idle??
Is it too rich or too lean??
I've heard that quad throttles are hard to tune on these cars...
I'm not sure if megasquirt has an idle lock function, but what you can do is set via RPM/TPS/Load a set amount of injector time or ignition timing to stabilise idle...
It doesn't look like you have any provisions for idle air bypass, and if your bypass screw is out of range i.e not getting enough air at idle you could use a trick that some larger engines do and drill a hole in the throttle butterflys. I think it is about 1/4 to 1/2 the diameter of the air bypass screw. You then can screw the screw in so it's closed and you have more adjustment for air if you screw it out again.
Otherwise install a bypass solenoid that works off PWM to control idle and run this to each throttle body.

the fun is over already...

thought I'd take the car to school today, 20km highway... but when I went back home and was passing by another car (130 km/h or something) the car suddenly lost power and I directly kicked down the clutch pedal and got off the highway.

Though it could be a loose spark plug cap or the fuelpump. So I tried to start again, engine was hard to turn but fired on 2 or 3 legs. The fuelpump was buzzing so that wasn't the problem. I couldn't reach the spark plugs because the enginebay was too hot. But those were fine too.

I called the service thingie to tow me away... in the mean time I noticed my coolant fluid was gone... just gone...

I refilled it a few days ago when the car was first fired up again (at that time the coolant was gone too...) Yesterday the level was fine... and now it was suddenly gone.

Anyway... It probably ran hot or something... quite a bummer, but no disaster.
I've bought a spare engine for 75 eur, just for the cylinder head...

Now I want to rebuild that engine: new rod bearings, new crankshaft bearings, new seals.
The only thing is that I really want to place new pistons... so that the engine is almost at best...
Problem is money... and I don't know what pistons to buy... stock? more compression? less compression for my dirty turbo/supercharger dreams?
Or just new piston springs and use the current pistons (which I don't know any mileage of)..

though choices...

anyway... I'll rebuild the engine, completely adapted for megasquirt with my new intake and stuff... and than it's almost plug & play.

This will take a while... but that's no problem... when it's on the driveway I can't drive it against a tree or something so that's a little pro... (no it's plain stupid to think that way).

Anyway... I had my week of fun

Nice looking car, Martijnus.

Also, your inlet manifold looks very nice. Are they the Weber throttle bodies? What injectors do you need for these? I like the welding on the manifold; really neat - did you do that yourself?

Have you tried sourcing parts from the UK? Fuel pump relays here are about £25, which is only around €35! They must be screwing in Holland worse than over here. Still, your insurance is really cheap...!

yeah too bad I crashed it the first day it came loose... it went down and the engine in the front moved a little... the green fan under it became 1000 lethal pieces

but I didn't get hurt
So when I find a new fan I can build a nice skirt and throw my ultralight airplane engine in the back for propulsion...
fun stuff

5hp lawnmower engine can lift 300-400 kg easily

Are there any small parts that I can carry over in my luggage for you?

But you grow some nice stuff in Holland that Paul could take back...
