Is it True ??? The MSP will be difficult to Mod ???

There is a huge difference in the 8.1:1 CR on the DSM motor and the 9.1;1 on the Protege. That's the reason we can only go up to about 8psi without some aftermarket timing control. But here's the kicker, our cars use coil packs and not just any timing control unit will work. The only ones that will work are basically piggyback ECU's like the link. The cheap ones that MSD and Jackson Racing make won't work. Also the rods are rumored to be weak on this car. Only about 2 people have broken a rod so far though.

1st Generation DSMs 90-94 have 7.5:1 comp.
2nd Generation DSMs 95-99 have 8.5:1 comp.

2nd gens can still run 20 psi without any problems with a 8.5:1 engine.
Me thinks that you could run 14 psi if the bottom end was beefy enough which I guess from what you are saying it isnt.

The crank is very strong, but the rods and the pistons are the weak links. Personally, I believe that the pistons are weaker than the rods. People that have used nitrous have either blown a hole in their piston or completely broken one in half. I've only heard of two people that have snapped a rod in half. Pro5 just broke one of his and it blew a hole in the side of the block.

what type of aftermarket pistons and rods are available for the engine?

Thanks for the info. What happened to your car?

I was on the way to work and some road debris knocked the oil line loose and all the oil spewed out. Now I have a broken engine. I am selling my turbo to get the repairs done.

Oh yeah, several companies make the rods and pistons for this motor. If I were you, I would spend the extra money and go with Carillo, I've heard good things about them. But there's also JE, Weisco, and another I think.

You should add that to your sig.
