Hi, I'm trying to figure out if an ignition upgrade is necessary to run a turbo 5 gen lude on stock h22 with about 8-10 psi and EMS and getting around 280-300 whp? Do I need this MSD ignition thing? Coil? Plug wires? Sparkplugs? Well, may be sparkplugs I need...but other ignition related stuff?

Does getting all this stuff adds hp/torque gain, fuel economy, reliability?

 

From what I've heard, I get the impression that OE ignitions that are running "tip top" should be adequatefor low boost.
Aftermarket ignitions are good, and can add power (more efficiency), but are mostly for peace of mind.

 

Does anybody else has something to say?

 

From what i've heard and experienced, the ignition isn't really need until you hit 400+WHP. But as discussed, make sure your current igntion is in good shape, good rotor, d-cap, wires and plugs. Any malfunction here will show up quickly in a FI car.

 

Yup, theyre really not necesary. However its just another one of those things that may give you the edge...

for 8-10 psi stock is fine. aftre 15psi and 450whp youll need an ignition system. i like the msd digital 6 or 7 myself.
