Turning my quest into a dsm.
 

I have been inspired by the great power and even better reliability of dsm's so I am changing my intake system and wiring over to a dsm setup so I can have one injector per cylinder instead of .5 .

So, here it goes, I will start with pictures I took when I first got back from China this summer, and I am still working on it, but now I am beginning to wire it up so it should run sometime soon.

Here after almost 2 months of sitting (hood wasn't open).

Here's how it looked when I left for China:

Here is where the stock engine harness came through from inside:
http://www.mitsustyle.com/photopost/...m/DSC01319.JPG

I had to remove the blower motor to get the harness out. That was annoying.
http://www.mitsustyle.com/photopost/...m/DSC01322.JPG

Just to the left of the white plugs is where it came into the cabin.

Getting things back together, starting with the brake booster. I had taken it off because the brake fluid was dissapearing, and I thought it might be flowing into the booster and filling it. I was wrong.

Here's the master cylinder attatched and you can see every mitsu owner's favorite wrench - the 12mm open end/box end.
http://www.mitsustyle.com/photopost/...m/DSC01341.JPG

Here is my new ABS elimination line. I bought it and it does screw in, but I need to get new metric threaded ends and get a flaring tool and do it the right way because the joints leak a bit. Oh, and the soft lines from the reservoir leaked also and that's where it was leaking before, I am pretty sure.
http://www.mitsustyle.com/photopost/...m/DSC01342.JPG

Got my endtanks modified to have 2.5" stubby ends instead of the 1.9" long tubes that were stock. But I didn't think enough to tell him to make them go straight up and down, his welding is top notch, but I had to cut the bumper support to be able to attatch tubes:

There it is. Remember, safety first - see the goggles?

Here's a test fit of the new manifold:
http://www.mitsustyle.com/photopost/...m/DSC01345.JPG

The fuel rail is made for FWD cars, not RWD, and there are little clearance issues, but with some ingenuity and a little money, I was able to avoid any major problems:
http://www.mitsustyle.com/photopost/...m/DSC01347.JPG

Little test fit of the lower + upper intake and TB, just for fun.
http://www.mitsustyle.com/photopost/...m/DSC01349.JPG

Remember that ingenuity and money thing? Here's my new fuel line. one part USDM, one part AUDM and one part nice dude at a custom hose shop =
http://www.mitsustyle.com/photopost/...m/DSC01356.JPG


You guys might recognize this quickly, it's a '90 CAS I got machined to fit in my head by a gunsmith who used to race boats and he does testing for big gun companies. 5 bucks. Nice guy.
http://www.mitsustyle.com/photopost/...m/DSC01360.JPG

http://www.mitsustyle.com/photopost/...m/DSC01361.JPG

Water neck installed, and fuel lines figured out.
http://www.mitsustyle.com/photopost/...m/DSC01362.JPG

New sensors getting installed.

Throttle cable figured out. It's held in place by a ziptie, I know this.
http://www.mitsustyle.com/photopost/...m/DSC01370.JPG

It's tight in there, hard to get that last injector plug on. Questers will notice that I rotated the throttle cable bend downward so the cable would be going in the right direction for the new TB location. I also switched the heater core hoses, people on SQC told me it might mess up the heater or how it works. But I won't be driving it when it's to cold, and when it's warm, I'll have the windows open. It always blew a little hot air at my feet anyway.

Lookin good chromepuff. I heared rumors about this crazy thing, glad to see it's finally coming together for ya

Re: Turning my quest into a dsm.
 

Little AEM 5 bar map sensor action. Thanks DB performance! :)
http://www.mitsustyle.com/photopost/...m/DSC01372.JPG

Got the fuel rail and vacuum lines setup. That's right my injectors say turbo on them.
http://www.mitsustyle.com/photopost/...m/DSC01373.JPG

The morning after delivery to the warehouse that it now lives in (the basement). My grandparents didn't like it sitting in their valuable empty garage space, so it had to move. Can't blame them I suppose, I'm just flesh and blood. ;)
http://www.mitsustyle.com/photopost/...m/DSC01374.JPG

It's so lonely down here.
http://www.mitsustyle.com/photopost/...m/DSC01385.JPG

I got the upper intake stuck on there with some RTV now, I figure it doesn't really need bolts. I got the pigtails for those two sensors in the picture at a junkyard. 5 bucks each. Kindof a ripoff, but it was worth it, if not for just the sensors, the fun of tromping through a junkyard looking for parts. :) I also found out that later model lincoln mark 8's are fwd. Silly ford.
http://www.mitsustyle.com/photopost/...m/DSC01382.JPG

This is what air is going to see: Pure death.
http://www.mitsustyle.com/photopost/...m/DSC01383.JPG

More pipes/hoses attatched. I'm excited at this point.
http://www.mitsustyle.com/photopost/...m/DSC01384.JPG

Re: Turning my quest into a dsm.
 

Here it is before I get started on it for the second or third time, I dunno, but when I was using some rtv I had this nasty itch on my side. I thought my finger was clean, but I had to itch and found out that I stained my white polo shirt that's pretty nice. Idiot.
http://www.mitsustyle.com/photopost/...m/DSC01381.JPG


This is so choice right here:
http://www.mitsustyle.com/photopost/...m/DSC01388.JPG

Little blurry here, but the welding is excellent. Shane Laske in Moorhead if anyone is ever in the arear and needs some great welding. He did my intercooler above too.
http://www.mitsustyle.com/photopost/...m/DSC01389.JPG

Here is what the cam angle sensor sees before the lights go out. What with it's one eye and all.
http://www.mitsustyle.com/photopost/...m/DSC01391.JPG

And the last picture for now. Like my garbage can? (at least it's not a garbage can't).

Re: Turning my quest into a dsm.
 

Looking good. Is that warehouse in China?

Re: Turning my quest into a dsm.
 

Sweet looking project. I've been wanting to get one of these and drop a 4g63/4 in it for a while, but haven't really had the motivation, or money for it. Some day I'll get it done...

Re: Turning my quest into a dsm.
 

Yeah, how'd you know? Someday I want to get another quest and leave the intake side stock and just upgrade the turbo. I really think that this project has taken too much money. The amount of research and finding parts and people to modify the parts equals a lot of time and money, and at first I'll really only be able to go for 300 hp. And that's just a guess, but it might do it with the stock intercooler. Anyway, for those wanting the 4g63 in the quest, I really would recommend just changing the stock turbo to a garrett with a decent exhaust housing and the only other mod needed is a maftranslator. It works great and they really rev once you open up the exhaust.

Re: Turning my quest into a dsm.
 

Well, I got some more done in the last couple days, this is the clean stuff, just wiring, soldering, heat shrinking, electrical taping and fitting. Kinda fun, and once you know where everything goes on the harness, wiring becomes much less scary!

Here's what's left of a '90 harness for the engine bay side.
http://www.mitsustyle.com/photopost/...m/DSC01410.JPG

Not much here either, except the other end looks like a rats nest still. Mitsu couldn't put the wires in some kind of order, could they? Noooo.. but it's ok.
http://www.mitsustyle.com/photopost/...m/DSC01411.JPG

Yarr! Thar she blows! Well, that's it with the wires through the firewall. Amazing that it had the length.
http://www.mitsustyle.com/photopost/...m/DSC01412.JPG

passenger and exhaust side: coil pack, transistor and noise filter, o2 sensor, knock sensor, and that's about it.
http://www.mitsustyle.com/photopost/...m/DSC01413.JPG

Good thing my harness only has long length, and not girth, otherwise it wouldn't have fit through that hole.
http://www.mitsustyle.com/photopost/...m/DSC01414.JPG

Passenger footwell. Enough length to put the new ecu where the stock one was and try to hid all the naughty bits (as my former boss used to say).
http://www.mitsustyle.com/photopost/...m/DSC01415.JPG

Next I'll be working on splicing wires for fuel pump, tach, power, switched power, etc. there's probably a good 10 wires to finish up then I can plug'n'play just like if I had an eclipse or something not as cool as a conquest.

Re: Turning my quest into a dsm.
 

That definetly does not look like fun.. I hate wiring work, even though Im ok with it. Good luck!

Re: Turning my quest into a dsm.
 

It's really not that bad, there's probably 25-30 wires taking care of all engine things. It took me a long time to get familiar with what was what. it is in the final stages though.

Re: Turning my quest into a dsm.
 

Holy shit dude that looks like a nightmare! Keep it up though, I hope to see this thing back on the street!

Re: Turning my quest into a dsm.
 

I worked on it for like 3 hours today and got it way better looking. I have just about 7 or 8 wires to connect here and there, then I have to get the CAS in place and sturdy (hardest part now), then plug wires, check fluids, and turn the key. Hope it works like that.

Re: Turning my quest into a dsm.
 

Nice. Looks like you're just about set to take that g54b out, and drop in a 4g64 :)

Re: Turning my quest into a dsm.
 

I see you put more pictures on this site of my CAS idea then on SQC.

You should update my thread on it with your pics.

Looking good though.

Sam.

Re: Turning my quest into a dsm.
 

so you gonna be more of a challenge once this is done? lol, you know i want your car.

Re: Turning my quest into a dsm.
 

Mindgame? Is that you on my local board? lol, sweet, I got banned from SQC, then I made an second name to cruise the boards, but they banned me again, so I'm not going on there anymore. This is where I will update stuff mostly (now).

Anyway, all I have to do is plug in the ecu and see if it starts (pretty much). I need an o2 sensor, need to wire up my knock sensor, and a power inverter for my laptop is sitting at the store right now. And I need to figure out a gauge temp sensor setup cause I have NO idea what's going on with that. I'll jsut trust that my thermostat is working :D

I'll get some more pics in a while. I'm selling my stock, modded intercooler on mnscc if anyone wants to check that out. ;)

Re: Turning my quest into a dsm.
 

Whats the map sensor for? you aren't going to be able to use that with the stock ECU.

Re: Turning my quest into a dsm.
 

What's a stock ecu? All I know is my ecu came it a blue box and connects to my laptop.

Re: Turning my quest into a dsm.
 

Not a bad way to spend $10,000.

Re: Turning my quest into a dsm.
 

I've got realtime 3d visuals of all 8 parameters of my engine. Actually I just made that up.

I do have a question, what is the firing order of the coil pack? does it just go 1-2-3-4? or like 1 and 3 are together? this would be a 1G thing, not sure if it's different for 2g's, i don't care.

Re: Turning my quest into a dsm.
 

1-4 and 2-3 are together.

Re: Turning my quest into a dsm.
 

yay, I plugged it in and got signals for everything. Holy crap is the aem complicated. I have some reading to do. And my tps is wired backward, I should have expected that, lol.

Re: Turning my quest into a dsm.
 

Here's some more pics as of friday. This is the new-ish setup for wiring. I bought some new split loom tubing for all this, so it'll be cleaned up more, but I re-routed the ignition wires and stuff to go through the secret passage above the wheel well.
http://www.mitsustyle.com/photopost/...m/DSC01468.JPG

This is where the stock engine harness came through. Now it's the knock and O2 sensors and the coil pack and transistor plugs.
http://www.mitsustyle.com/photopost/...m/DSC01469.JPG

And here's the location of the stuff.
http://www.mitsustyle.com/photopost/...m/DSC01467.JPG

And now I have to connect the plug wires, switch the + and - on the tps, make sure I have the right settings for starting it up and it should go. :) yay.

Re: Turning my quest into a dsm.
 

Good luck buddy!

You went farther than I thought you would!

Re: Turning my quest into a dsm.
 

So hows this coming?

Re: Turning my quest into a dsm.
 

Cool! I'm glad somebody else finally got the idea working!

You better post videos when your finished...

Tuck them wires!

Re: Turning my quest into a dsm.
 

This has been put off for a couple weeks because of various delays. But I think this friday I'll be working on it, maybe try to start it. But I think I need longer plug wires. And of course, it depends on if fuel doesn't leak etc. If it starts, then I will not worry about tuning or driving it untill I get the boost tubes worked out, I/C mounted and all the little stuff.

Re: Turning my quest into a dsm.
 

I posted your pictures for you over at SQC.

Re: Turning my quest into a dsm.
 

Thanks! I'll just keep adding more here, and if you want, feel free to put 'em up there. I will be taking more tomorrow (friday).

Happy birthday to me. Apexi GT core. It's damn huge. I hugisized it for 79 cents.
http://www.mitsustyle.com/photopost/...m/DSC01480.JPG

I have to cut the bumper supports quite a bit, and I can't really do that in this warehouse I'm in (I think) so that install might have to wait. then I'm getting some Al. pipes, I'll need a bov, the new manifold (yet to buy) and the exhaust welded up and it should be all done mechanically by then.

Oh yeah, do I need a special timing light to check timing since it's wastespark? Or will it just read twice what it really is?

Here are the latest pics, I cut away a good section of the bumper to make way for the ginormous intercooler pictured above. I think it'll be ok for the time being, I plan on having it re-inforced later, once the car is running. Next I have to cut the frame rails to match the removed section of the bumper supports. Who needs collision protection anyway, right?

This is my AEM file I'm working with right now, the only thing I changed since I've tried starting it last is the rev limiter "load psi fuel cut" setting, which was -14.69PSIg. I thought maybe that was the reason it would crank and stumble, but never start. I'll try it later, if anyone else wants to take a look at it and suggest improvements, please do so, I know Ryan is going to take a crack at it, he's been really helpful with this slow-going process. I am quite the n00b with the AEM, but slowly gaining knowledge. THANKS again!

(I had to put it in a zipped folder since you can't attach .cal files. :) )

Re: Turning my quest into a dsm.
 

It's Alive!
Thanks for the hints, and I finally figured out how and where to add fuel with the help of some good friends. No names but his initials are Josh Swanberg (sp?). Thanks man! Ryan, you too. Now I can focus on the details and get 'er ready for tuning.

Oh and unfortunately it still sounds like a conquest hehe. (I spose that is actually a good thing).

Re: Turning my quest into a dsm.
 

Grats mang.

Re: Turning my quest into a dsm.
 

Awesome!

Re: Turning my quest into a dsm.
 

Glad my "Hints" helped ya ;).

Re: Turning my quest into a dsm.
 

Good to see that thing is still alive, its been too long, oh how i miss thee.
our frum anything action should be a lot quicker these days, don't ya think?

Re: Turning my quest into a dsm.
 

Pics don't show - still have that girl turbo on there, Andrew? Jesus cries when a 12A and MPI are in the same engine bay!

Re: Turning my quest into a dsm.
 

If the 12a is still in there, it is only a temporary matter. I have seen the replacement, and it moves a little bit more air...

Re: Turning my quest into a dsm.
 

That isn't saying much!
