mfarino Posted March 6, 2012 Share Posted March 6, 2012 Hi everyone, this is my first post, but I'm sure not my last. I don't mean to sound like a noob, but has anyone wired an early Chevy V8's oil pressure sending unit to their Stock oil pressure gauge? It seems simple, connect a single wire, yet mine doesn't seem to be working. Any suggestions? Quote Link to comment Share on other sites More sharing options...
matt_w Posted March 6, 2012 Share Posted March 6, 2012 I think most people (at least the JTR suggests) to use the stock Datsun sending unit. The threads match up pretty closely to a 1/8" and won't leak if you use enough teflon tape. Quote Link to comment Share on other sites More sharing options...
Miles Posted March 6, 2012 Share Posted March 6, 2012 (edited) The JTR book explains how to adapt the datsun sending unit to the Chevy block. A 1/8" NPT nipple and right angle adaptor is all that is needed. The Datsun threads are close enough that it can be screwed into the 1/8" NPT right angle adaptor using some teflon thread tape.

mfarino Posted March 6, 2012 Author Share Posted March 6, 2012 Thanks for the photo Miles, thats very helpful! I got the Z as a rolling body with no motor 3 weeks ago without the original motor, so hopefully I can find a factory style oil pressure sender at the local parts store. I've already gotten the fuel system hooked up, engine installed wired and running. The only things I can't seem to get working are the oil pressure and engine temp gauges. My fingers are crossed that your suggestions work. Any idea about getting a Gen I SBC coolant temperature sending unit to work with the original Z temp gauge?

GOTHALOSISM Posted March 6, 2012 Share Posted March 6, 2012 No clue, I put a Datsun sending unit in my LT1 and even then the stock gauge won't work for the water temp. Even a cheap aftermarket gauge does not work. Quote Link to comment Share on other sites More sharing options...

Motor Sports Auto (MSA) and JTR sell the adaptor so you can use the Datsun temp sensor with the SBC engine. You should go to the JTR website and buy the JTR 240Z V8 engine swap manual as it explains exactly how to install a V8 in a 240Z. MSA sells the Datsun oil and temp sensors.

jt1 Posted March 7, 2012 Share Posted March 7, 2012 The JTR adapter is a slick job, it works like a charm. Makes a nice clean installation. jt Quote Link to comment Share on other sites More sharing options...
