Solder or Crimp - [injector clips]

[isnms]

I'm going to install my Lex and 550's this weekend when I replace my intake manifold gasket.

Which is best method of splicing in the new injector clips?

Solder or Crimp

When the experts get here, I hope they say solder...............that's what I did to mine about two weeks ago.

I would solder. Not an expert though lol.

Soldering is tough to do correctly if you have limited experience. I have quite a bit experience soldering, and I still opt for other types of connectors when working on anything in a car.

EDIT: I don't know if anybody considers SC and expert :dunno: :dunno: : http://www.supramania.com/forums/showpost.php?p=484644&postcount=4

There we go I guess.

 

[MKIIINA]

solder ftw. make sure you heat shrink it too!

 

[BorHor]

Actually soldering can be bad if you don't do it right.. for example on the M3 we have.. Some of the solder broke on a few sensors with moving parts broke. And even in the radio had broken solder where there is no moving parts. I guess just make sure you know what you are doing.

That's good stuff :bigthumb:

If you're gonna use crimp connectors, use the noninsulated ones, and heat shrink over them. I use either method, depending on what I'm doing, but always use heat shrink to seal the joint.

AEM EFI Basics recommends crimp over solder.

In preparation, I picked up some Krimpa-Seal type butt splice connectors. They have the heat shrink built on.

Solder FTMFW with silver solder. Very very low resistance and use good quilaity shrink wrap. Crimp connectors will corrode.

i solder everything i do. but then again, thats what i do. its a lot easier to screw up crimps than it is solder for the average guy.

the hardest part about soldering the clips is usually the copper wire is fairly oxidized. you'll have to clean it and use a bunch of flux to get the solder to wet properly.

the reason crimps is recommended over solder is the vibration resistance. in harsh conditions, solder can crack. but id still recommend soldering the connections. it will be a better connection unless you are using high quality crimps and crimping tools.

bare crimps, solder to seal, and two-layered heatshrink for the paranoid mechanic :aigo:

 

[Datsrboi]

Wow. I thought soldering would be the top choice but I guess crimps have there spots too.

 

[super.secret.supra.club]

I did crimp + heatshrink over it, but that wasn't for my injectors. Solder can get brittle and then crack on you, I haven't done any homework on the vibration resistance solder though.

Bottom line here is to do what you are more comfortable with. If you take your time and use the right tools, you are likely to get a perfectly reliable result with either method.

I crimp...high temp connectors, heat shrink over them.

Tis true but to answer the question again (we've been down this road before) crimped joints are superior if done right. That means the proper tools and terminals. AMP PIDG is pretty much the standard in aviation where other than in avionics soldered joints are generally prohibited in aircraft. They're all I use. Get 'em (and the tooling) relatively cheap on ebay. Fwiw a properly done crimped joint is gas tight and thus can't corrode.
