1hotkadota - it was nice meeting you at the track last night!
What a great night to play! Hope to see you out there again.
DSW - Yeah, I remember the "good old days" when we could go
round and round. Nowadays there are too many people and they
break on the track alot more often and cause long cleanup delays
all the time.

It was great meeting you too Duner! I loved watching and hearing your truck haul ass! Mike's truck runs very well and it was nice meeting him too. Let me know the next time you guys go down there and I should have my LSD put in by then and I can get better than a 2.213 60' time:) What was your best time of the night? I only got 2 runs out of the night. But they were still very fun. The best part was coming in .1 seconds behind the Cobalt SS supercharged I raced the second time. I would have beat him but I had a crappy launch. But still got him through most of the track. He finished at 95mph and I had a measly 88mph! Although my run before that was 15.316 and his was 15.378.
Did you run your oil feed line for your turbo from the pressure sending unit? Also, what do you think is the best way to cool the intake charge, water to air or air to air? Where did you get your PCM flashed for the 4.7l? Sorry for all the questions but I forgot my pen and paper on Fiday:)
Later dude!

Racing is almost always fun!
The truck ran:
11.14 @ 123.06 mph
11.11 @ 122.92 mph
11.01 @ 123.34 mph
with a best 60' of 1.58.
Hopefully it will get back into the 10's with a little cooler
weather.
For the 4.7 I got my oil feed from the oil galley at the driver's
front ower corner of the engine - next to the oil sending unit. I
went with the air/water intercooler system because I thought it
would be a cleaner install than the air/air. I got my 4.7
computer flashed at Z-Industries in California. It wasn't a flash
for boost, but works well anyway with the 24# injectors. I don't
mind questions.... ask away!

I just bought the Bosch 24lb injectors from a 2003 Cobra. Are those the same ones your using and if so, how do you like them?
I also have an adjustable FPR. Will this be useful in fuel management, and if so, how do I plumb it in sync with the Vortech FMU?
I read somewhere that you were able to run up to 5psi on the stock PCM. Is this true? If so I would do that for daily driving and purchase a separate PCM for track usage.
How did you get that check valve on to where the MAP sensor is so it doesn't see any boost?
Since the 4.7L will retard timing the higher the intake air temp is, could I put a resistor, kinda likes Bernd's old design but to make it seem warmer, that would give me a small amount of timing control?
I know I'll think of something else to ask but until then GOOD DAY SIR! And thanks!

Yes, the 24# injectors I'm running are for a newer Cobra. They
work just great.
In order to use the adjustable FPR, you will have to install a full
return system back to the tank. With the FMU and aux. fuel
pump, it just pumps in a loop until it sees boost. I don't think
you'll need the FPR at all. Go with a 10:1 FMU plate with the 24#
injectors.
You can run all the boost you want with the stock PCM. The
issue is the stock rev and speed limiters. With boost, you will
quickly reach both limits even with low boost. I wouldn't bother
purchasing a separate PCM for track usage. You won't like
driving the truck with the stock one once you get a reflashed
one anyway.
I removed the MAP sensor from the front of the manifold and
found a plastic nipple that fit into the manifold tightly. I added a
hose from that to the MAP sensor, with a "T" in the line going to
a large check valve that usually is used on the vacuum booster
for the brakes. Orient the check valve so it bleeds boost but
closes under vacuum.
I wouldn't put a resistor on in place of the IAT. You only want
the timing to retard when in boost. The rest of the time you
want all the timing you can get for throttle response and fuel
economy. It helps to spool the turbo quicker too!

Awesome! That answers alot of my questions for now. Now I just have the task of routing my exhaust up to where the turbo will sit since I don't have a custom manifold setup. Maybe I situate the turbo in a tranverse manner. You wouldn't happen to hae some extra manifolds layin around would ya?;)
What kind of oil temps are you running?
See you out there.

Nope. No extra manifolds around.
I never measured the oil temps. The engine temps were always in
the 180° range, so I don't think the oil was heated much.

Ah I was just jokin about the manifolds. Good to know about the oil. One less gauge to try and stuff in there.
Do you have to worry about passing emissions? I'm worried that if I take out the cats and 4 O2 sensors, I won't be able to pass or get fined for removing emission control equipment. How did you deal with this? What kind of mileage did you get?
Since my Dak is my daily driver, can I just ship a PCM out Z-Industries and have them flash that one? If I do that, what flash do I ask for or should I just call them up and talk it over? I have the auto tranny, do you think that will cause issues with tuning?

My understanding: it is a Federal offense to tamper with the emissions equipment on a motor vehicle registered for street use. I would guess that if you can do all your turbo stuff, but leave the emissions stuff intact and functioning you won't be violating that law.
As for passing emissions testing: some states/counties do visual checks and will fail the vehicle if the visual doesn't line up with what they are looking to find. In CA, even if the vehicle sniffs fine, it'll get failed on the visual if something is not right. That's where the CARB/EO numbers come into play. If you don't have to submit to a visual test then this wouldn't be a factor.
Sorry to slow down your project, but these are some of the things you're gonna need to address for the complete package. For me, the visual requirement is one (of the many rea$on$) I'm not gonna turbo my QC any time soon.
What's your left foot doing?

Damnit! Thanks Modain. Well it looks like I might be doing the rear mounted turbo setup after all if I want to stay CARB compliant. It seems alot easier that way except for the oil pump and whatnot. I'll keep you guys updated.

Hey guys, long time no talk. I got busy and neglected to check on the forum for a few weeks!
Rammer and I haven't even played on his Ram or any of my projects either, so it's been ignored.
I wish I could have meet you guys at the track last weekend. And worse yet, I heard Duner was going to try and get into the Pinks event in Tucson, and I had other (non Dakota) friends going as well and I was on call this week so I couldn't dare drive down there :(
1hotkadota, don't worry about emissions here. It's not like California and as long as your cat is in place and no codes read from your OBDII port you will be fine. :)
Don't do the rear mount. Yukk!
Let me know if any of you are planning on going back to the track in the near future.

I can't figure out how to run my pipes!:(
I guess I'll have to keep on keeping on with the routing. :) I may just t-off of the pipes and run one under the truck to go up front and up to the turbo. We'll see.
Glad to see you back on here. On call sucks.
I got my cobra 24lb injectors in 2 weeks ago and my FMU came in. I need to do the zener diode install soo too. If you guys have some extra time this weekend, gimme a call or shoot me an e-mail so I can come over and see Rammer's truck and maybe you guys can help me figure out the plumbing.

No problem. The Zener Diode trick is pretty easy to install, but you have to install the diode in the correct polarity or it wont work.
You need to install a nipple into the front of your intake manifold to route to a TEE then to your MAP so you can hook up the check valve.
That's not too hard, but almost requires pulling the intake or some accessories in front of it.
You could do what Duner dod for the exhaust. That is just taking the left manifold's pipe and running right back to the right manifold. Basically removing your Y-Pipe and making a pipe go from one manifold to the other with NO tee or Y. Then cut a hole in your right side manifold to come up and into the turbo.
Let us know what's up. This weekend you could drive out to see us, as Rammer and I live in the same neighborhood.

But I've got the three cats and 4 O2 sensors so I'm not sure about how to reproduce Duner's setup without cutting out at least one cat and 2 O2 sensors. I'll keep contemplating though.
Your right about the map sensor. That thing is right behind the A/C compressor and looks like a real pain to get to. No matter though, I'll wrestle that nipple(huh huh, you said nipple)in there somehow. By the way, what kind of nipple is it? I'm not even sure of what it should look like:)

I am not sure what the nipple was like. I had something shoved into my extra intake that I had hacked onto my Dak for a while. The MAP mount was different on the 2000 than on my 2003 so I had to hook a hose up in between. I musta had some sort of something shoved in there, but don't remember now!
The 3 cats thig SUCKS! But maybe, hust maybe I'd just remove the cats and do the pipe as we spoke. Then run one cat after the turbo under the truck with two O2 sensors in front of the cat and the other two after. $10 says the PCM works just fine.
On my truck it had one cat and one O2 sensor before and one after.
I went to true duals. The sensors are only on one bank and the truck runs fine. You will be doing the opposite. But all that matters is the front O2's put before the cat for the PCM to read A/F mixture and the two others put after so it sees the cat is in place and working.
The emissions test is usually just getting the OBDII port connected and a simple inspection. Them teenagers are in a hurry and just look for a cat to be in place. Not sure if they look up the exact configuration of the cats or not.
Rammer passed with his aftermarket setup. I have yet had to go through emissions with my 2003.
Ya know, maybe Duner's white 4.7 Dak had the dual cats like yours? I think his was a 2000-ish as well. But not sure if that cat set up was year specific.

Oh right on dude! Then thats what I'ma gonna do! Thanks for helping me finger that out:) Would a J configuration hurt flow that much? Because, I could leave the drivers side cat on, lop off the passenger side, run a J pipe up from the passenger side with a connnection for the drivers side up to the turbo and run it like that. I already have a J pipe from a 300ZX that should fit pretty well, I'd just have to tweak it to make the drivers side connect and voila! Turbo. I'll get to work on it. Let me know about the diode this weekend and I'll bring my pipes and show you what I have in mind.

What do you mean by a J PIPE? If that's the pipe going from the drivers side outlet to the passenger side outlet, then I wouldn't have a CAT in between there.
You can cut a hole into the side of the passenger side manifold to make the pipe go into the turbo from there. then the downpipe from the turbo going back down under the truck can have ONE large CAT and then back into your muffler (if you use one) etc.
I'm sure we could find some time to look at the stuff. As long as I don't get roped into going on a family drive this weekend, etc but we have been kinda broke lately so I will likely be at home most of the time.
