Hi Sumo,
Maybe thick rods, maybe not - if your car is a MY95 but was built in late 1994, it may have the new engine which means thinner rods.
If you want a supercharger to deliver reliable power, I recommend a standalone ECU. Yes, it has been done on the stock ECU but personally I wouldn't it... and you definitely won't get the best out of it.
Timing will normally advance with RPM on a naturally aspirated engine - but timing needs to be retarded once you add boost. Stock injectors and fuel pump will have a limit and its always a risk pushing them close to their maximum capacity. Furthermore, you need to run a fairly rich air/fuel mixture on boost - and your stock ECU and air flow meter can only deliver so much.
Get it wrong and you won't need to strip the engine to find out what sort of rods you have. It will show you.
If you do choose to go with an aftermarket ECU, something else you'll need to consider is all the other ECUs in the vehicle that won't recognise a foreign ECU. Dashboard, traction control, ABS, suspension control - they all draw signals from the engine management system to operate. Take it away and they will not function correctly. You'll need to find a solution to retain full operation of these systems, otherwise you will have to live with warning lights and malfunctions.
Bite the bullet and get some injectors, fuel pump, fuel regulator and ECU to go with your supercharger. Make it even better with water/meth injection, extractors and exhaust to get the best results. Study each of the complimentary systems and find out what signals they need to run properly, or find an installer who is switched on and can do it for you.
This will give you a reliable setup.
Cheers,
PB
