Alright... S52 OBD1 conversion question...

[MR 325]

Converting an S52 to OBD1. I have an S50 here, complete with all parts so no issue there.

Here's my question...
Can somebody give me the temp sensor wiring information? I'd rather do this myself than pay for a Turner adapter.

Thanks guys.

The Turner Adapater doesn't work for E30s does it?

It doesnt. Dont buy it.

you cant use the s52 dual purpose coolant temp sensor. the resistance is different and will not work with the stock e30 temp gauge. there are a few options, but the easiest is to tap the head. use the coolant temp sensor for the ECU from the S50.

[BeirBrennerE30]

to get the correct temp reading you need to use the e30 temp sensor so you need to

a) tap the head and install like the obd1 motors
b) buy the zionsville manifold and put it in your throttle body heater feed as close to the head as possible. (this is what I did!)
c) install sensor n the place of the fitting for the feed for the throttle heater. I dont like this since no one can confirm that it doesnt screw up coolant flow in the head
d) mount it into some other coolant hose. I think "the racers market" sells an adapter to put it in the upper rad hose.

And they won't even return your calls...

no shit. unless you are prepared to drop thousands of $$ with them they don't have time for you. i hope this shit economy teaches them some humility. fucking assholes.

[hugh jass]

if you've got the engine out the cleanest and neatest way is to drill and tap the head.

Yeah the one time they answer he says tough luck. Bunch of assholes.

O 3000 post.

I don't see how tapping the head is easier than using the Zionsville Manifold. Which is precisely what I plan on doing.

[FredK]

It's not easier, but it's cheaper and looks better to drill and tap.

I've never had to get any tech support from Turner, but they do put out some nice and affordable E30 chassis reinforcement products.

[jrdeamicis]

Just drill and tap the head.

I filed down the sensor threads and re-threaded for the throttle body warming circuit nipple hole.

thats pretty slick
