Ned's 91 GSX

[ned032002]

I should have started this thread a while ago but I'm Ned and I own a 91 Eclipse GSX AWD as I'm sure you already know. Well this winter I plan to do some more moddifing basically to support what I already have plus some additions. We'll if your interested in a full mod list just check out my cardomain, link is at the bottom in my signature.

My winter plans are to replace the stock pump w/ a Walbro 255 and also rewire the pump. My one question about doing this is, I have an amp in the trunk already w/ a 12v lead from the battery to supply it's power. My question is, to rewire the pump you need to run a new lead wire to the pump, can I just use the same lead the amp uses? Would it be dangerous for amp and fuel pump running off the same 12v wire?

I'm also planning on a FMIC w/ the short route piping. With this I will also need to get a slim fan so what fan would you guys suggest without spending a fortune but still getting what I need. Considering a NX kit to spray nitrous on the intercooler, haven't exactly decided on this or not.

I have a dump tube that I'm thinking about installing, I keep talking myself out of it because I'm worried about how loud it will be. I've been having problems w/ keeping the downpipe nuts tight, they keep losing up after about a week of driving. I only drive about 30 minutes total a day and after a week you'd think the downpipe had come completely detached it's so loud.

I also need to take the FIAV block off plate back out because when shes cold she doesn't want to idle at all. I still have the idle surge that I can't seem to be able to figure out, been dealing with that for 2 years now.

Going to paint the car in the spring, not sure on a color yet. I'm thinking maybe gunmetal on the bottom and paint the spoiler, roof, and hood all black. Another color idea is burnt orange on the bottom and black the same as the idea above. If I do go w/ black I don't want it to be stupid glossy. I'm not sure exactly what I want but I have plenty of time to think about it.

Last but definitely not least I need a damn good tune done to her. I heard of a guy up in Rochester that deals a lot w/ DSMLink so I may take it to him after I the above mods done. I really need to get the surge taken care of first then I will move to the next mods.

I didn't get any new pics this year except for a few random pics but next year I will make it happen. Any suggestions please reply, I welcome all thoughts.

Just started tearing it apart to get the FIAV out and just kinda get things cleaned up before I do the FMIC and what not. I did a boost leak test and there were no leaks so I guess my search continues w/ operation idle surge.



I pulled the TB off of course to get the plate off and so I decided to test the ISC/IAC motor to see if were bad or not. I put this one in hoping it would cure my issue but I never tested to make sure it was good. Well according to the Vfaq, there are 6 pins on the ISC motor. It says that that each coil should have a resistance between 28-33 ohms. I tested it the way it said to and these were my results:
1-2 > 30 ohms
2-3 > 55 ohms
4-5 > 30 ohms
5-6 > 30 ohms

So it looks like the "2-3" coil is bad. Need a new ISC!!

Having an issue getting the inside bolt on the o2 housing off. Any suggestions?

The the fuel pump you can use the power wire from your amp. I ran mine this way for about a year with no issues. Make sure to wire up a relay on it so its not on all the time.

[ned032002]

I was going to rewire w/ a relay like the vfaq says, I actually bought an installation kit off ebay that provides all that is needed to do it. I thought I would be able to use that wire but I didn't want the bass to hit and reduce the juice going to the fuel pump but in reality that shouldn't make a difference because no matter what hot wire I tap into the volts will be the same. Thanks for clearing that up, it wouldn't have made much sense running 2 wires so that makes things easier.

Any ideas on the o2 housing? I think if I lower the alternator I might be able to get to it then. Any thoughts?

Edit: VICTORY!! Got the O2 housing off, looks like I need a little bit of modifing to get the dump tube to work, as of right now it's blowing straight into the cross member below it. Got quite a bit pulled off today on my day off, here's a couple pics.





Got Radiator, fans, dump tube, and j pipe off and disconnected. My next steps are to get the bumper off and the vacuum lines cleaned up, going for the vacuum line removal. Makin it happen as often as possible.

Also need to get a 2g TB elbow in the future, it's not pressing right now but later in the future I will need it.

Looks good, I need to do some winter cleaning as well but no money. I wouldnt recommend a nitrous intercooler sprayer, you will get far more gains running meth injection for the same price. I used a u joint and some skinny hands to get at that bolt on the vackside of the o2 housing. If you do go dump tube let me know how it it becasue IVe been debating that as well especially becasue i Have wicked boost creep with the CAT out but love the exhaust without the cat soooo much.

[ned032002]

I won't be driving it for a long time, at least for a few months so. I don't have a lot of money so that's why it's going to take me all winter to get what I want done. Stuff like the Vacuum line removal is going to cost me under $10 and even replacing the o rings in the power steering banjo bolt is only going to cost me under a dollar so stuff this that I can't wait to get done. I need to get an elbow welded onto the dump tube to make it vent properly other wise I'm going to have too much heat in the engine bay.

See in this pic how the dump is going straight into the crossmember below? Thats where I'm going to get an elbow welded on so it follows the curve of the downpipe.

[ned032002]

So I want to get the vacuum removal done today but having an issue figuring out what each of the items are in the this picture.
Here is what I'm trying to do


Before


After


See in the top right corner of the first picture where it shows the Fuel pressure solenoid and the Evaporative emission purge solenoid. On the car there are 3 "things" in that corner of the car. In the Chiltons book it kinda looks like 4 things. So I can't figure out what is what, can anyone specify what is what? Thor, this might be your que...your a 1st gen guy.


I'm going to guess that the FP solenoid is all the way to the right but not positive about that.

[ned032002]

Figured the above issue out. I have a new question, what should I do w/ the large vacuum line on top of the charcoal canister? I probably shouldn't just plug it but should I hook it back up to the intake or will that create unfavorable conditions? Help

[Blackcrow64]

I just ripped mine out completely. No sense in just plugging it and leaving it there if it can be taken out. Unless there is a sensor in it for 1g's?... Either way your gonna get a CEL from it.

[ned032002]

I'm good to go I think, I narrowed it down by process of elimination.

Going to try and get the fuel pump rewired this weekend.

[ned032002]

Figured it out by process of elimination.

Going to try and get the fuel pump rewired this weekend. I still need to get the Walbro 255 but I can at lease get it started.

[vanilla gorilla]

Cant you like, delete out the CEL's with DSMlink, so that, they wont come back on. For things such as emissions delete.

[ned032002]

That's what I'm hoping. I'm going to look into it once I get the car all back together which won't be for a long time.

[ned032002]

Made some progress on the car today...very little but enough to say so anyway.

Ran the 12V lead wire from the battery to the fuel pump for the rewire. I've been soaking the piss out of the fuel line connection and the nuts that hold the sending unit in place. I'm pulling out that sending unit and installing a different sending unit w/ the walbro 255 installed in it. Check out how bad the original sending unit looks like...not sure how it's going to go w/ getting it out. Here's a few pics to showing progress.



Take note of the black wire in this picture, it's not even connected anymore. It was so corroded that it just kinda fell off. No worries the other sending unit will replace this anyway.
