HAHA that's why I want to race now.

I kinda figured as much...better get him now Chris, HAHAHA.

Just a quick update...I had my friend from NM look at my car tonight. He has an FD and knows them in and out; used to own a rotary shop down there. He verified what I suspected...the turbos are not hooked up right AT ALL. He said he was amazed I was building boost period. We're going to get rid of a lot of this crap and do the poor man's non-sequential mod on it. I'll probably start taking stuff apart this weekend...intake manifold, throttle body, IC piping etc has to come off so the turbos and controls can be easily accessed. That stuff needed to come off anyway so I could look at the wire for my coolant level sensor, and see if it's broken / shorted somewhere under there. I'm getting excited about getting this car running right again

Unfortunately, it won't do me much good...he said I won't be able to pass emissions, even with a stock exhaust and a good tune. Look like I'm back to square one there...

Well at least you guys figured out the problem. What all was hooked up wrong? So it wasn't the hoses with the pills huh? LOL Good luck!

Ranger · Postby **Ranger** » Fri Jun 26, 2009 9:14

Nah it wasn't those hoses, they're in place and the pills are in them. Thanks again though. Pretty much everything else is hooked up wrong though LOL. Clearly Precision does NOT know what they're doing when it comes to the turbo controls on these cars. One of the wastegate lines is hooked up to a source of vacuum where it should be seeing positive pressure. Two others that should also be seeing positive pressure were capped off, and one of the caps was cracked (boost leak anyone?) A bunch of other stuff is completely disconnected. Oh well, we're going to get it all fixed next weekend, hopefully.

Awesome man. Is your friend still in town? Maybe he can tell me if my lines are routed correctly haha. Even after going single turbo I've been having issues with either getting too little power or too much. I want to make sure my vacuum lines are set up right before I go plunk down on another boost controller.

Yeah, actually, he just moved here, so he'll be around lol. I'm sure he'd be happy to take a look at your car, too. I'll let him know you're interested.

Forgot I set my photobucket account to private, that's why the pics aren't showing up. I'll fix it in a bit.

Oh OK cool. I'll hit him up next time I'm in Denver with the car then.

Sooo my car is more messed up than I thought, haha...I've said it before and I'll say it again, Precision doesn't know what they're doing when it comes to FDs, that's for sure. I am continually amazed, that they let this car out of their shop in the condition it's in. Nothing is mounted where it should be...wires and vacuum lines just all over the place. I can't wait to get it hooked up right, probably tomorrow or Sunday. But it's still going to be a mess. It looks like this now...note that the only things I disconnected were the throttle cable and a few sensors. The rest were just like they are.

Most of the crap that is disconnected is emissions related. But, this crap is SUPPOSED to be mounted onto a rat's nest. Instead it's just kind of hanging. I don't know if it was like that before Precision got their hands on it, but my guess is no. Those definitely aren't the vacuum lines I had on there before, because they were blue, not red. Hey Eric, didn't you said you had a spare rat's nest somewhere? If so, I'll buy it off you. I don't want to leave this like it is. Oh and I STILL can't find where that coolant level sensor wire is going. It just disappears under the alternator.

Also, you did water / meth injection on your car, right? What setup did you go with? I think my car needs it. I've heard it works wonders for overheating rotaries.

speedjunkie · Postby **speedjunkie** » Sat Jul 04, 2009 9:14

Yeah I have my old rat's nest in my garage. I'll bring it up the next time I go to Denver. I do have water injection but I don't have it installed yet. It's FJO. The FJO kit is kinda advanced and it cost me about $700 and it didn't come with a tank. But a good kit that is a little more basic and easy to set up will be around $350-400 and will work great. I got the FJO kit because it is able to read off of injector duty cycle, whereas all the others read mostly off of boost, etc. FJO reads off boost and the others too, but I'm gonna use injectory duty, that's why I got it.

wow they really messed that thing up. Did you get it fixed?

Ranger · Postby **Ranger** » Mon Jul 06, 2009 9:14

No, we both forgot it was the 4th of July weekend lol...and this weekend I'll be at PMP driving the 944...so looks like this is getting put on hold again. However the conversion seems very simple so I may try it myself. At this point I don't think I could make things any worse :lol:

Soo long time no see! Sorry I haven't been around much. A couple days after the MoL meet, I had an accident while mountain biking and broke my right hand. Don't worry...I'm fine, just have a cast on for a while. By the way, I do have pics from that meet which I'll be posting shortly.

Anyway...I'm finally going through this mess. Basically, most of the wiring harness is not in terrible shape, unlike what I thought...just a few things that need to be re-soldered. Coolant level sensor and several coolant temp sensor lines being part of that (go figure). The big problem, the one that made it look like utter crap, was in the ignition circuit. This is my understanding of it...the car had an FC coil for the leading ignition, which was spliced into the FD harness (they don't work together at al) and ziptied to a fuel line (whoops). This FC coil was being powered by a separate ignition box, since the FC coil doesn't have one / isn't compatible with the FD ignitor. BUT both coils for the trailing ignition were still being powered by the stock FD ignitor, which is still in place and working great. I have no idea why this was done, but it's all going back to stock soon, because right now it's ugly and a fire hazard. I have to get the ignition coil for the leading plugs and replace that part of the harness, which is beyond repair.

The turbos should also be fixed now. Obviously haven't been able to test them yet, but they are hooked up right. The guy who is helping me has an FD with a non-sequential mod like what is now done to mine...I rode in it yesterday, so much better than my car when it was sequential. I can't wait to see the difference...though it'll probably be laggy / have a surge in power, given that my intercooler is way too big for the stock turbos. Is anyone interested in buying a big Greddy FMIC / trading for a smaller one that will fit an FD?

Damn man, sorry about your hand. I barely got to talk to you at the meet. Good to see you're getting everything squared away.

Alot of people use FC coils in their FDs with great success (as Borat would say!). What do you mean they don't go together? I don't remember which is which, but I believe the FC coil used is only the one to replace the center FD coil (leading I guess) and like you said, the two trailing are left stock. I didn't know you needed an aftermarket ignition for it though. Simon was running a Jacob's ignition for his FC coil, and possibly the FD coils too. I can understand wanting to go back to stock though, alot easier to keep track of for one.

I have a stock IC in my storage if you wanna use it for now, until you get a smaller aftermarket IC. I still have that rat's nest too haha.
