I want to swap a sr20det into a 72 240z but I'm worried about replacement parts. I know the sr20de and the sr20det have interchangeable parts but what about the electrical sensors. Where do you find a throttle position sensor or an oxygen sensor or any other electrical piece of junk that will fail over time. I've done a lot of research on this engine and I could definitely do the swap. I'm worried about what might happen in a year or so when a sensor goes bad and I cant find the part anywhere. Also, is there anyway you can hook up a scanner to an sr20det so you can check sensor readings. I've found it very frustrating working on an obd1 vehicle due to the poor sensor info. Are there stand alone setups you could use or does JWT have something. I know this is more a question for hybridz.org but I like this site and the people here. Any info you guys could give me would be appreciated. Thanks
