i have a 91 civic hatch bone stock d15b2 motor...i did an auto to si 5 speed swap..i drove it to another town about 15 minutes from home to get an estimate on exhaust and i noticed at 55 mph my tach is readin 3,000 rpm,and at 65 its readin about 4,100 i have a faze aftermarket tach so i know its right but i dont think those rpm's are right and im thinkin thats gonna be kinda hard on gas...can anyone tell me whats goin on? id really appreciate the help

really??

Does the car skip or sputter...or are you going strictly by what the tack is saying

 

faze????

 

ur speedo is prolly the inaccurate one.

 

FYI: Faze gauge's are probably some of the most inaccurate pos gauges that are out. Why do you think they are so cheap?

TRUE...I've had customers bring me NIB Faze gauges that didn't work properly...but they did have the kewl indiglow affect

 

i was curious because it dont sound like its turnin the rpms it says...hell i paid $115 for this tach brand new i dont know whats goin on but i just find it weird that my tach is showin 3,000 rpm at 55 mph i figured is was just the gearing of the si transmission

 

snip the wires.

then but connect them to a autotach from kragen and see if you get the same RPM readings.
or you can buy a 90-91 Si cluster and install it

 

id like to have an si cluster but i cant find none here in missouri...people are like bums with food when in comes to honda parts they see it they snag it up

 

I have an 89 Si cluster that might work for you... Let me know if your interested.
THanks!!

 

how many miles are on the clock and what would you want for it? do you have to do any re wiring to install it in my dx? it was an auto car and no factory tach

 

I did the same thing on my 90 dx.
It just plugs in and bolts up, there are 2 plugs that you dont use in the 90-91 si cluster that were previously used in the auto cluster to display which position the shift lever is in.
Good Luck

 

I really dont remember how many miles are on the clock... Id be willing to let it go for $50+shipping.
Let me know if you're interested.

 

let me know how many miles are on the clock and shoot me some pics if you can and ill let you know if i want it or not id like to have a manual guage cluster so i can get rid of my automatic shift indicator...im tired of people askin me why does your guages have the automatic gear indicator when your car is a 5 speed i still wish my tach wasnt readin so high im gonna pull it out later and make sure its on 4 cylinder

 

with that tranny at 65 mph in 5th gear you should be turning around 3000 rpms. so there must be something wrong with the tach. or maybe the speedo is wrong.

 

its a rebuilt trans and has a brand new speedo cable so i dont understand whats goin on

Your lack of reading comprehension might be the problem. More than one person has already stated that your brand of tachometer is crap, hence a good possibility of not reading correctly. To be absolutely sure one way or another, take the car to redline, and see where the tach says the fuel cut is. If it's accurate, you should be hitting the factory fuel cut (unless you've got a chipped ECU for god knows what reason).

 

i think ill pass on redlining my motor thanks for the useless info
