Ok let me start off by saying i've searched, but this question wasn't answered in anything that came up.
I have a 91dx hatchback and I wanted the SI cluster. Went to 3 different scrapyards and couldn't find a single crx or civic si. I didn't wanna go home empty handed so I figured I'd try the EX sedan cluster(10 bucks, who cares if it doesn't work). So I plugged it up, fit perfectly and worked. The thing is I'm not sure if the readings are accurate. I just got the car, so I still have the d15b2, and dx tranny in it. The previous owner had a giant autometer tach in it so that's why I wanted the new cluster. Getting off topic, but anyway... before it read around 3750 rpms at 80mph in 5th gear. On the new ex cluster tach it says about 3100rpms at 80mph. Does anyone know which is more likely to be accurate? Thanks

 

imo im going with the autometer because it is aftermarket

 

yea i have a 91 crx dx and at 80 on the highway im hittin upper 3's

 

^^^^ same here

 

im canadian so is mish, wel at least live in canada haha. anyways when i go 80mph or 128.74km/h im hitting upper 3k rpm when i go 140km/h 87.00mp/h im hitting almost exactly 4k rpm.. all on dx tranny d15b2 with mpfi swap. hope that helps

 

yea 130 km/h is about 3700 mine is dpfi though

 

dpfi and mpfi doesn't really matter, haha, not to be an *** or something, but it would be the same for both

 

thats what i thought, i mentioned just incase
