Using stock gauges with an engine conversion
Is it possible to get the original rev meter and speedometer to work with a CA18DET engine and gearbox?

Yes..

Needs a cable drive for the speedometer (I've seen an ae86 cable stuffed into a CA18 gearbox working), but without a different ratio gear it will show the wrong speed for sure.

Tachometer can be used with ECU signal with a tach signal booster.

I would recommend using the Omex one for this, it's inexpensive and easy enough to fit.

Hi Jezza, do you have a link to the Omex part?

I've been looking at the speedometer, it seems I need to buy a mechanical speedo drive for my gearbox (which doesn't seem easy to find). I'll also need to buy a cable.

My diff is a 4.6 so i'll need to get a gear to match. It all seems like a pain but hopefully worth the effort

You can also buy a part that lets you set the speed yourself+cable,but forgot the name.Will look it up.

I deal with omex, they dont show the converter on their page. I blive they retail at 25gbp +shipping to wherever you need it send to.
They ment to convert a + square signal to a - peak signal.
So if your Nissan Ecu got a digital output, as in square and +, the omex converter works very well!

Omex converter is 15 gbp.. look for Omex Tachometer driver, you'll find it in webshops. Emerald also sell a tach driver, but it's 35GBP IIRC.

You can make these converters yourself (I have built quite a few), but even I will no longer invest time and effort into something that can be bought for 15GBP. Thats a properly fair price and you get production quality too.

If all else fails, you can send Omex an E-mail directly and inform them of what you need. [email protected] Thumbs up!
