Just wanted to say thanks and ask a question

[The Shape]

I posted in here a few times over the past couple of days asking questions about a '93 coupe I was looking at as a daily driver. I brought it home on my trailer saturday night. They told me they thought it had jumped time. After looking it over I determined it had a bad ignition module. I replaced it and it started right up! Wanted to tell everyone who replied to my threads thanks for the help. Ok now for the tech question. What is the deal with 4 cylinders and 8 spark plugs?????

the 91-93 2.3 mustangs used the dual plug set up for emission reasons. However on the plus side the engine is rated at 105hp whereas the earlier 2.3 was rated at 88hp. The other changes were an increase in compression, mass air EFI, and a roller cam setup, instead of the slider cam setup. Some say the roller cam is responsible for most of the hp increase.

Adding a turbo to this engine is fairly easy, because it has mass air you can use 30 or 36 lb injectors from a 5.0, add the exhaust manifold and turbo and get a good power increase. If you plan to go over 10psi of boost you will need to replace the stock cast pistons with forged pistons. You can find more info at therangerstation.com

One note from experience, if you replace the plug wires, get the set that has the built in boot puller for the drivers side #3&4 cyl. It makes replacing plugs a lot easier.

The roller cam is responsible for most of the power increase. And just so you know, EFI came out in 87, not 91. You're right about the emissions control reasons for having a dual plug head, I think that also there was an original intent to have the motor burn more efficiently than the single plug head. I guess those two things are linked though.

Wait til I tell my '84 it isn't EFI!!!







-but I know what you meant.

so as long as you stay under 10psi of boost a stock motor will hold up, as long as the motor is in good shape?

Good question > Anybody?

hold up? i wouldn't say so. last a whole summer? maybe if your good to it. If your motor is in good shape then i wouldn't recommend TRYING to ruin it. if you plan on doing a REAL turbo swap down the road soon, then go for it. Just start saving up for a new motor right when you bolt up that turbo. But for as much money you would be spending on a turbo, maifold, ect. You could likely find a complete turbo motor and drop that in. Then you wont have any headache causing problems down the road. Plus you could run twice as much boost, which would feel like twice as much power.

No turbo for this car. It is just gonna be my daily driver for running around town to the store and stuff.
