I have a D15 from a '93 del sol. Would the '89 HF motor have more hp from a head swap or should I swap the whole motor. I'm hoping to hear the head swap since it's a lot easier and quicker than a motor swap. The motor was free and I don't plan on sinking in lots of money into my car. I've had it for 6 yrs and love the 45 mpg it gets - I drive about 90 miles a day during the week. Also, if anyone needs del Sol parts LMK.

HF motor would be less HP then your stock car. Top of that you need to do some work to convert the HF motor to an obd1. The HF is good on gas also because its tranny. What are you trying to do more HP or better fuel eco?

 

the hf is an 8 valve head. not going to happen, bud.
