Just so you know your instructions work fine. Thanks..

Yep the 8920 is what works.

Hey nigel, did you ever have any issues with the tach on this after you removed the resistor from the tach circuit?

yeah, it's a challenge to find leaks sometimes, and many of the a/c shops have slackers working in them. I think you get your own refrig detector from harbor freight for less than 50 bucks... Might be an idea?

This thread illustrates why I always try to put back in, what the system was designed to run with originally. Even if it requires R12. It's cheaper IMO to fix the leaks, and repair the system, and recharge with R12, than it is to convert it to some pieced together ineffecient system. If you go to that, you might as well replace the entire system with one that was designed for the refrigerant you want to use.

Yeah, it's a HC (Hydrocarbon) based refrigerant. These work ok, and the head pressures are nice and low, but the charging is tricky, and you sight glass never looks right, and they don't work as well with older TXV type systems like the Datsuns. OT type systems work pretty well in. Least from my experience.

yeah, it's a 97.... nevermind.

You can get R12 on Ebay.. http://www.ebay.com/...erant&_osacat=0 If you can fix the leak, and the system only needs a couple cans, it's much cheaper to fix then retrofit it.

that universal stuff is crap.. Get what it was designed for. I've tried that for R12 and 134A systems and it never really works that well.

20 bucks I have two, one old style for E31 head, and one newer style for 77MY 280 with NM47 head. I'm going to use one of them, not sure which one though. I think either will work, seems the newer one is a complete stamped unit, whereas the earlier version is modular.

Got one from a old L24? Would that work?

update. 240 engine was trashed. The bores were completely rusted and would take 120 or so to clean them up. So I got a great deal from Dave Rebello on a 3.0 stroker setup. I send him the N42 block, E31 head, and 240 rods. He works his magic and sends back. Then I will assemble the engine and away we go. Estimates are around 250 to 275 hp with SU's. Chekcing on Bore Bore pricing for SU's today.

Thanks, I need as much luck as possible!!

Hey guys, been a bit since was here. I'm starting in on the 2.4/2.8 engine work in about a week, so I'll let you guys know what I find on the 2.4, and if it's complete toast.

This is s 4/71 build, so maybe it's OEM.
