|
|
I was wondering if there could be a handy overview of all that is known about tune-ups and adjustments to the standard 602 engine. I want to be well oriented before i make a decision about how to beef up my engine and give my deuche a little more edge.
What i know:
Lightened flywheel:
+ Improves pick up acceleration
+ fairly cheap (around 75 euro)
- less stable in low RPM
- no increase in BHP
Cylinders and pistons with higher compression rate
+ increase BHP
Anyone have more ways to modify the engine? In the end i would like to make a decision how to positively improve my engine. I do not want to keep repeating that of course this choice is a personal matter and i think everyone should do what he likes best. |

classical tuning stuff:
- polish your intake manifold
- use bigger carburator "injectors"
- be shure that your engine gets fresh cool air ( perhaps use a "dust- sucker" )
- set up everything perfect. ( frehs oil, valves, ignition and so on )
- be shure that your oil-filller is ok ( if not a few hp will be lost...)
- be shure that your baal bearings are ok.
- lighten your car, put everything out you don't need. (power to weight ratio )
- more pressure in your tires
If everything is ok the 602 engine isn't as poor as everyone says !
One thing is really important:
don't use delta-mics ! :) _________________ in rust we trust... |

You'll find a lots of information (bad or good)...
At the end thanks to tell us which setup you've done and what are your impressions on it.

Yeah, Deltas are not "aero", whit wide tyres you destroy aerodynamics even more and get also more rolling resistance.

|
|
One of the most imporant thing to get right is a good spark.
The 123 ignition is a good idea which is ment to be 'fit and forget'
6 mounths ago I bought a stock 2cv with 18,000 miles from new, never been over 60 mph, more services than I could have thought posible, one every year with MOT, '1,000 miles a year' and a 123 ignition.
In every respect the car is like new BUT it drives like a pig on wheels!
I tried,
Carb clean and setup, no better
New oil/filter, no better
New plugs/leads, no better
New coil, slightly better, top speed up 5mph @ 64-66mph
So off with the grill and took a look at the 123, what a mess! The monkey who instaled it must have used a hamer, oil was every were and was out of alignment by a mile.
I have put a new 123 in, the old one looks to be in need of a sripdown as oil is stiil coming out of the pcb at the back.
Things were looking up, 70mph , but still did not feel like it should, all my other cars have much more go, this engin feels layzy.
Last resort, a new coil, the yellow one from ECAS, a lot of money, but what a difference!
Starts first time, 70+ mph and drives like a happy motor.
So we can do a lot of tuning to our 602's but it needs to have a good spark!! |

I'll second that. The yellow coil made a big difference to the starting and running of my 2CV... |
