Injector upgrade questions
Hi all,
I'm looking to bolt a few upgrades onto my '86 951 soon. I have a t04e turbo, MAF and a few other goodies in a box ready to go, but I need injectors to go with the setup (I'm having chips custom-made to handle this).
I located a deal on a set of four Siemens 75# flow-matched, low impedance injectors for about $240 (new). They show a spec of "2.35 Ohm coil resistance/low impedance/low-z" (whatever the heck "low z" is. . .)
I'm assuming I'll need to add resistors totalling up to 3.15 Ohms inline on the injector signal wires to bring these up to 5.5 Ohms to be compatible with the weird Motronic 5.5 ohm signal and not torch the DME, right?
I'm sure some of you guys on here have done this before - any good recommendations on which resistors to use? I kinda' don't want to trust Radio-Hack grade technology on my 951. . .

Thanks, I'll check it. I was wondering if there were any specific ones for automotive applications that someone might recommend, but it sounds (more or less) like a resistor is a resistor. Good enough I guess.

No offense, but if I wanted a static database of search information, I'd go to Clark's Garage or something like that. The advantage of a forum is that you get current and timely information validated by honest-to-goodness individuals. With a static searchable database, it's far too easy for information to become outdated or stale quickly, and then never get updated.
So anyway, a static database (or searchable one) is great for information that doesn't change - like how to change a timing belt. It's pretty ****-poor for questions like "what's the latest knowledge/pricing someone has about XXX?" See the distinction?
I love these people that love to slap others with "use the search feature" for everything (on this web forum and a number of others I've seen). Ultimately they're just a-hole wanna'-be moderators. No offense, don't take it personally, but it comes off as a pretty dickheaded move. Just don't be a deek and nobody will accuse anyone of being one, k?
Why does it bother you so much anyway? 'cause I put less than a kilobyte of bandwidth onto an Internet web site? Do you have some huge lock on ballast resistor market share and you want to quash the thread lest your near-monopoly and plans for ensuing world domination be thwarted by the public sharing of knowledge on the subject?
Boo hoo.

2 ohm %1 tolerance 25 watt resistor in aluminum housing. Im assuming the value of 2 ohms is correct. $4.50 each.

Since your a local guy, I won't level the launchers at ya just yet...
I'm not one to preach about the virtues of being polite, but judging from the responses here, it wouldn't hurt to exercise some. I'm pretty quick to launch a "go search" post and the only time I show restraint is when the person doesn't really know what the question is that they are searching for. That's called lost.
for the level of mods you are doing, ten year old data still applies to your 20 year old plant.
OT, I've written a few posts on the injectors mainly comprised from what I have learned form previous searches, vendor data, and web searches. If you can't find what you are looking for, then start a thread stating so, or PM a knowledgeable poster from one of your searches.
My typing is pretty slow, and it kinda irritates me that I took the time to do this, hopefully it was worth my while.

What I really like is that a new user with 65 posts who is about to start down the upgrade road, which means he/she is gonna have lots of questions and need lots of help, is attacking a user with over 3000 posts. No offense, don't take it personally, but it comes off as a pretty dickheaded move. Just don't be a deek and nobody will accuse anyone of being one, k?
Poor may not know yet what a helpful and well thought of member Testarossa is, but it might have been a good idea to check before calling him an "-hole wanna'-be moderator." I bet Poor doesn't get any really cool avatars for quite some time.
