So I have a '93 Del Sol S and I have the option to buy a new cylinder head for 300+ or a clean running '94 SI engine (complete no missing parts) for 650. Is it better to swap for the new engine or just have my engine repaired with the new head? Prices are for parts only. I need to do one or the other no matter what, because a spark plug is broke and seized so tight in the head that even a mechanic couldn't remove it.

See post "Spark Plug Screw Up" for details

 

dont both the del sol s and the si both have d16z6 engines? it depends on your budget and your plans. you could buy the si engine and take the head off and use it and possible build the other engine or you could just save a little bit of money for that cylinder head
