OK how can I fix it. Or could I use the DX distributer on an SI motor would it work.

Im thinking your distributer is fried, Not positive though. They are known to go, I had mine replaced last year http://www.hostboard.com/ubb/smile.gif

Though Im not sure about you only going to 3000 rpm. Wheres NC REX?

do you know if the distibuters are the same or no

I am pretty sure the distributors are the same across the 4th gen Civic spectrum (USDM anyway). They are all D-series engines so the distributor should be the same. Also 88-89 Integra distributors I think will work.

4-doors rock & I want a ZC motor! Willing to rebuild. Anybody got one for sale?

does anyone know how to fix the 3000rpm problem and to fix the Code4 crank angle sensor
Thanks for your help so far guys really appreciate it.

Only D16A6 Si Distributor will work on Si engine........D16A6 engines in the following:

88-91 Civic Si Manual
88-91 CRX Si Manual
88-91 Civic and CRX Si Canadian Models - Auto and Manual
90-91 Civic EX Auto Sedan
88-91 Civic RT AWD Wagon Auto and Manual

Have a parts yard to a computer search for an 88-91 Civic or CRX 1600cc engines distributor.

do you guys know what the reving problem might be

3000 rpm may be the igniter unit. I beleive the DX and Si units are the same. As far as I know the igniter fails partially....only causing problems as the rpms increase until it will act like a rev limiter with some sputter. But I would check part numbers between them. I'd check the numbers myself as I have both...but I am slammed busy and getting near exhuastion from side-work with everything here lately.

Your replacement distributor shouldn't run but $60~$80 bucks typically with a high side of $100 if you order it from another parts yard.

so I should check both and if the same switch it and then see what happens because I get a code 4 on the ecu
woeld that have anything to do with the igniter

I'll take a picture of my DX converted harness and post it later tonight. It shows the correct pinout for the Si distributor connector of the DX harness. I also need to dig through some swap notes and make sure I can give you the correct pins on the ECU.

thanks for helping me I really appreciate it and I'm learning alot from this also

ok I'll check back later

The numbers on the Igniter unit are the same I changed it and I'm still geting the same problem

i had the same problem with my 89 integra and the problem was with a sensor, not sure the name sorry.

But i am currently having the same problem now but i belive its the ecu fault

i would call local honda dealer just for more info

Sorry, Been forgetting about the harness. Will take a picture tommorrow.

have you taken the picture yet

Email me and I'll send you the pictures...I just sent them to someone else this week probably thinking it was you.

from the pics I cant really see anything do you have any pics of the wiring harness on the computer

No that I don't have. And I can't get them because the Civic I did was demodified back to stock.

It would be really hard to photograph every connector because the resolution and color sucks, and secondly, their are just too many connectors that get extended or repinned in this swap.

Tell you what though...I jsut put together the D16Y8 engine last night with Si manifolds, ditributor and such. I have a DX harness that's spare sitting hidden in a junkyard waiting for my to knab it...so this monday or tuesday I'll knab it and when I do the swapover for the wiring...I'll take picture of the harness and try to make a journal of the modifications.
