I am in the process of swapping an ubercharged '99 engine into my '92. I have most everything accounted for, but wanted a second opinion on several things.

Can anyone verify my identification and approach?

The first three are from the 1.8 '99 motor

Part number one: I think is the idle speed controller. I wonder if we
can do without it as the wiring is totally different than the 1.6






Part number two: I believe to be the exhaust gas recirculation
control. Thinking of blocking of the control plate and plugging the
opening on the header and not installing the crossover tube.




Part number three: Secondary optical timing sensor? Thinking of just
leaving it unconnected.


The last one is from the 1.6.
Part number four: Unknown sensor at the back of the block near the water outlet.


Cross posted on m.net as well. Thanks for looking.

 

#3 = cam angle position sensor (I replaced this on my car during troubleshooting). #2 = egr valve. Think you're right on #1 as well - someone here can confirm ? (#1 is either diff on the '00 motor or was part of the SC kit).

 

#4 is the temp probe for the gauge in your dash.( i believe. i'm a 94 guy so what do i know?)

 

#1 looks like an air valve for the AIC.
#2 looks like the EGR
#3 looks like the CAS
#4 is the temp signal to the dash

 

Brain has them labeled right. For a block off plate you can either make one or you can just pinch the tube shut and braze it so it doesn't leak.

 

#2 looks more like a bypass valve for the SC than an EGR... but I don't know the NBs well.

 

Thanks guys. Question on the temp sensor for the dash, I would obviously like to preserve this function. Do any of you know the voltage and corresponding value for the sender? I was thinking I might use the eManage Ultimate to read the ecu temp input and output it to the dash gauge. Anyone (Joe Perez are you listening?) know if thats a reasonable approach?

 

Just plug the wire in there it doesn't change from year to year from what i can tell.
