na blocks are built just as strong, the only difference in blocks is that turbo cars have oil plumbing for the turbo built in. aside from that, the cast pistons and head/valves and intakes are the main difference between the motors. the reason they have been neglected in the tuning department is that turboing a dual plug motor is pretty much just to say you did it instead of being "the" viable 2.3 turbo option (and most good running dual plug turbos will run a turbo computer instead of the method they used on my car [big mass air/injectors]). eventually if all the 2.3 turbos crack the heads, someone might pay attention to tuning dual plug computers because that will be the best cheap head available, but until then, theyll still suck ***.

 

i dont know if i forgot, but what do you have? do you own a modded 2.3 n/a? if so, can you show me a list of stuff done to your car?

 

nope, dual plug turbo. it's hard to justify modifying a naturally aspirated 2.3 unless you have some badass parts hookups

 

yes very true.

 

yo jug, u ever see this before? its a sh!tload of work, but it would be well worth it for a 2.3(T) owner.
