ok tried searching and found nothing(mabye its the way i typed it in the search i dunno)

but anyways I have a b16 in my 88CRX. Im trying to figure out some things about it from the previous owner.

Now when is v-tech sopuses to engage? I keep hearing that its sopuses to be at 5,500 rpms but I can clearly hear mine change over at about 4,700-4,800 rpms. I belive the motor is a gen 1 obd-O type system


also I hear alot of the b16 came with LSD any to check to see if mine has LSD?

 

I have ab16 in my 91 hatch si, it is also the 1st gen b16a1. Mine kicks in a 5200 rpms every time. Im running a PR3 ecu.

It has a chipped PR3 ecu and was kicking in at 4500rpm and was way to rich.. So I switched to stock PR3 ecu

Hope some of this helps..

 

one for sure way to check if the tranny is lsd is pulling out the axles and if you can see light through it then its a lsd. its a lot of work for a check but its a for sure!

 

hmm thats wierd why my v-tech engages so soon then. Mabye my ecu is chipped or somethings.

As for checking the LSD that sounds like alot of work...

 

vtec buddy. vtech is a cordless phone so maybe people call you and thats when it engages so early. there is No H in VTEC

 

my LSD has 2 stamps in the case that says LSD
another easy way to check is by driving the car
do a burnout.....should have 2 skid marks afterwards

Not completely true. My old 4 speed off of my d15b1 could leave two marks. At a stopsign do a burnout and turn. If you have two skids you possibly might have an lsd and if you do a one wheel wonder then you dont have an lsd. This is a more accurate way to tell then just doing a burnout.

 

Jack the front end up, not quite sure if it'll work depending on what type of transmission you have.

Turn one wheel, and you should see the other one eventually spin. Thats how you know its LSD.

Non LSD will not do that

 

hmmm when i launched hard i left 2 markers but i dunno if thats a very accurate way of telling.

 

pull a axle it only take 5 mins and if u can see through and see the other axle end the tranny its lsd if not you will see a pin goin through the diff blocking it
