Hi Muddchucker, I've done this swap. I have the 13B-t red block and that is a strait plug and play on my 1981 BJ42 with stock 4 speed. All I had to do was swap my 3b starter and alternator over. I've added a 12v-24v converter to connect the VSV vacuum switch that shuts off the motor as my VSV is...
Thanks guys, now I just need to tidy up the wires and get a new 2.5 or 3 inch exhaust. The glowscreen I will sort out later.
It's almost Weekend and time for some :beer::beer:
Yes this is my 12v alternator from my 3B engine. It does have a pump at the back but it didn't have the vacuum pipe connection on it like the 24v alternator. We just swapped the 2 oil feed fittings on top of the pumps over.
Good news guys and girls got it sorted. Had a blond moment.
A mate of mine came over and we had a play with the VSV lines. Looks like I needed the vacuum from the alternator to feed the VSV.
What we did was replaced this on my 12v alternator...
with this one of the 24v alternator. This...
Hi Marbles,
Thanks for your reply. I had the vacuum line circled in blue blocked off, no luck turning the engine off via the key. Also I had the vacuum line going the the AC and the line going to the 2 solenoids not sure if that is what it is called blocked off. I will test this again tomorrow...
Thanks cruiserpilot. Best of luck with your truck. The 13B-T just looks mean in a 40. This VSV setup is my last obstacle that I need to overcome then I'm a happy camper.
Please let me know if I'm missing something here as I'm a completed novice with cars. This is my 1st engine swap that I've tackeled by myself. My mechanic skills are to only check oil, water and breaks LOL.
This is the vacuum VSV and how it is currently connected.
This is the step up converter that I used and it is working.
I know that connections looks like the wild west, but its just temporary.
So this is where I'm at now. Any help will be appreciated and once I got this sorted, I will...
Good day boys and girls,
1st thanks for this lovely forum and its members, without this I would be lost and very rich, but now I'm poor and own a Cruiser :flipoff2:.
I'm a proud owner of a 81 BJ42 since 2012-08 and loving it. The truck had a 3B engine and a 4 speed gearbox in it. A few months...
