vmax2000cc Posted April 30, 2020 Share Posted April 30, 2020 Hoping the knowledge of the Supra gods can answer this. Would a 27060-46300 alternator be a direct fit to a J Spec N/A (including plug fitmemt) and if not, what would I need to do to get it to fit? Many thanks.

Chasz86 Posted April 30, 2020 Share Posted April 30, 2020 Can't answer your question but if you are looking for a similar alternator to the oem, it is possible to repair original for £20 parts and 2-4 hours of time. If I'd a refurb on my alternator years back before the forum so no write up I'm afraid but simply remove alternator opened it up found the diode pack and regulator, (basically two parts bolted inside. And searched the parts code written on them. A local marine and auto electrical store had them in stock. Paid about £20 for them popped them back inside bolt alternator back on checked that the float voltage was ~14V and did not exceed when engine was revved. Been working a dream for 3yrs now. Fixed a lot of electrical gremlins too. Quote Link to comment Share on other sites More sharing options...

Chasz86 Posted April 30, 2020 Share Posted April 30, 2020 Tbh I can't say exactly, but firstly as may expect battery kept getting flats from not charging then I think because I didn't have a clean DC supply, random fuses would blow, dash lights giving warnings intermittently, maybe due to sensors dipping in and out. I just know that once alternator was refurbed any electrical faults made sense where before they didn't, my background is in electrical so I'd be tracing a fault all around the car from fuses to relays to sensors thinking why am I getting problems everything seemed to test correctly individually but would still get trips or warnings etc. Not sure how much that helps was several years ago now.

vmax2000cc Posted April 30, 2020 Author Share Posted April 30, 2020 Been offered one my main concern is the plug fitmemt as I am aware there are two types? Thought maybe being Jspec it might be different. Quote Link to comment Share on other sites More sharing options...

Chasz86 Posted April 30, 2020 Share Posted April 30, 2020 Also the wiring diagrams show connector shape I'm sure. Could maybe dig it out of pc if you send me an email address Quote Link to comment Share on other sites More sharing options...

Mike2JZ Posted April 30, 2020 Share Posted April 30, 2020 All 1JZ & 2JZ alternators are plug and play in terms of plug used and mounting holes. The only difference other than the current output of the alternator itself , is that on NA and TT alternators, the position of the alternator plug is slightly different, but there is enough wire on the plug to reach either, so usually not a concern.

vmax2000cc Posted April 30, 2020 Author Share Posted April 30, 2020 Forgive me for being thick, but I were told there are two types of plugs for these cars, circle plug or oblong? Quote Link to comment Share on other sites More sharing options...
Mike2JZ Posted April 30, 2020 Share Posted April 30, 2020 Forgive me for being thick, but I were told there are two types of plugs for these cars, circle plug or oblong? Correct, although these days it's rare to to see a round style plug as they were only on super early engines or older 7M GTE and so on. 9/10 times its going to be an Oval plug for both TT/NA. The part number you mentioned above uses oval plug, so will be direct fit to your NA loom as is. Quote Link to comment Share on other sites More sharing options...
