"COBRA INTAKE SWAP!!!!!!! Beginning....."


          

Now. As soon as the lawn crew is gone, my baby is going under the knife. She will begin her transformation to a better breathing, and more attractive version of herself. Here are the before pics:







And incase you don't remember what my baby looks like, here's her current pic...a very dirty 97 mark viii base cordovan with 137k on the clicker. Current mods include a jmod, deep sump trans pan, trans cooler, walbro 255lph fuel pump, fluidyne 2 core radiator and mustang fan, bilstein rear shocks, koni adjustable front strut inserts, lowering coil spring conversion suspension, shortened sway bar end links in the rear. And more maintenance items than should ever be done to one single car over a 3 year period.

Don't forget - pics are a good thing. Especially since I have a Cobra intake sitting in the shed waiting to go on.

I don't see why not. Tonight I'm mostly going to be finish sanding my upper intake and starting to lay the paint out on it. I may start on the disassembly but probablly won't get far. However if you want to come over tomorrow morning I have no problems with that Glen.

Parts Pix:

Included are the fuel lines and an fittings off of Jeremy's old setup. The IMRC, upper and lower intake gaskets, cold air intake, reusable filter, EGR gasket, IMRC's, and IAC bypass line with it's canister are all also in this picture.



Not needed for the swap, but was purchased a month ago with the intentions of swapping it in when this swap was goin down is this 180* TSTAT.





But Justin...you might ask...why don't you have any pics of the upper and lower intake???? Well here's one of the upper...but no pics of the lower as I'm keeping the color a secret until the final product is revealed. Or at least until later on in this thread when I get around to installing the lower and posting it's corresponding pic.

Let the work begin. Pulled her in.



But safety first. Remove your battery and relieve the pressure from the coolant system.



Next remove the air intake tube and filter assembly. Sorry I have no other pics, but there was only one bolt holding mine in...as I knew this swap would occur soon and the intake silencer off my car has been in a land fill for a couple of years now.



I recommend taking this time to change out your tstat and flushing and cleaning your radiator. But you definately do not have to. However now is the time to drain at least enough of the antifreeze so that there is none left in the coolant crossover tube. I was forced into this as my radiator has developed a leak. Probablly just stress cracks from being straitened last year after the accident that had left it slightly bent.

Why are you using a Mustang fan, they don't flow or cool as good as the Mark VIII fans which are pretty much the best you can get stock or aftermarket. Also, I wouldn't use the hypertech t-stat, they are the 2V thermosats which will work in your car but they are not as good as the Napa 180 degree thermostat which is actually designed for the 4V.

I got the tstat from napa, and that was the part # that I found on the forum. But I'll definately compare it before I install it. And the mustang fan bolts onto the fluidyne radiator which is for a 97+ mustang. Plus I'd like to know exactly what the flow rate of each is, because the pitch of the blades of the mustang fan are much more agressive than the mark viii piece which leads me to believe that it has close if not better flow potential than the mark viii piece. And after a few times of sitting in 100+ degree weather for an hour at a stand still with the a/c blasting and had no overheating problems. I seriously doubt that there will be any problems. I do appreciate your concern though. Any advice on the intake swap?

That's really not the case. 01+ Mustang fans flow just as much if not better than the stock m8 units. The fins have definitely bigger pitch. Tell my car it's not getting enough cooling ...


Justin,
make sure you reuse the m8 IMRC plates unless you're porting the ones you got from the older cobra. The gaskets IMRC to head are different though than the ones you have up there. If you need to, you can actually reuse both sets (lower and upper).

Crap I didn't know the gaskets were different. I bought the gaskets for the cobra piece thinking they were the same. Should I just reuse the old gaskets and save the new gaskets until I can get the cobra IMRC's port matched to the heads on the new engine I am about to start on?
Also if you have any other tips or helpful advice I'd greatly appreciate it. On a side note...how's the eaton blown mill doing, have you put many miles on her yet?

Justin

You can reuse the orange head->plastic IMRC gaskets as well as the ones between the IMRC->intake. Just inspect them for any damage (tears, nicks etc) and you'll be fine.

You seem to have your work cut out for you. Anything you need, just ask.

Eaton's fine. I've put about 1500 miles on it so far due to Carlisle trip. I averaged 24mpg with the new motor and 3.73 gears. It's running on mobil 1 already.

Honestly, I've never been happier with this car's performance.

24 mpg...that's impressive I don't care who you are.

Yeah, I've got a weekend ahead of me. The radiator is going in to the shop in the morning and they promise it back after lunch. The intake removal is very easy. I can almost do this with my eyes closed. The intake to imrc gaskets will be replaced with the new ones. If the lower's are knicked or otherwise damaged I may just replace them with the cobra version that I have...if that means that I have to use the cobra imrc's then so be it...but I hope not. The fuel lines are going to be a god send that's for sure and the tps wiring will go easily. Now the egr tube and the throttle cable bracket will be trying. If you know an easy way to reshape or cut the bracket that will help...and I'm sure I'll be posting more in the morning.

Thanks

I posted these pictures on the other forum, but here they are so you havea all the info in one place. FYI, this is the stock 2nd gen mark VIII bracket cut in half. I should've sent you them with the lines, as I won't need them anymore

OK, how do I get the extra slack out of the cruise control cable? And the fuel lines work and look great.

You relocate the module inside the driver's wheel well.

I reused the same bracket that mounts it in front of the ABS module
and placed it directly under the battery, against the wheel liner, at a slight angle.

OK, here we go again with more pics. Sorry that I didn't take enough pics during the install, but I'll try to talk you all through it. Since I left the camera inside I just completely forgot about it. But the car is running and finished. Lots more throttle response, no CE as of yet, but I havent driven it much, and a good bit more power especially on the upper end of the rev range.

Remove the upper bracket for the altenator.



Then remove the altenator.




Then remove the nuts that hold down the coolant crossover tube and gently pry the tube loose. I advise replacing all o-rings in it at this time.





Then remove the egr tube from the egr valve.



Remove the 4 bolts retaining the upper intake and remove it. Then unbolt the fuel rails followed by the 16 or so bolts holding the lower on. Gently slide the lower forward and the fuel rails will come out. Then remove the lower intake.







Disconnect the old fuel lines from the filter and return line connection in the ps fender well.



Then install the an fuel lines and make sure they go through the same hole as the stock lines.





Here is where the lines were removed from. Sorry it's side ways...just trying to exercise your neck muscles.



This is my failed attempt at relocating the egr tube. Well the tube is now in the right place, but I then realized that the mark viii egr valve contacts the wiring harness when installed on the cobra intake. So to prevent a melted harness I decided against making it functional.

Next remove the fenderwell liner from the ds front wheel. And relocate the cruise control motor from it's stock location to under the battery tray. This way you have enough slack to hook to the throttle body.





Ok, now put the imrc's on, followed by the lower, then torque all the bolts and studs down. Now on the vacuum lines you are on your own. I had lots of spare fittings and such lying around so I was able to improvise. If you want pics of the lines just ask.

Thanks to you holding the light and pointing out all the broken vacuum lines and not drinking my water and such. Thanks Glen.

And my darling wife for helping me out and keeping me sane through it all. You guys have to consider that this was done in my garage here in Houston TX with no fan. I lost 3 lbs from friday to sunday.

I have the cobra throttle body, but didn't use it as it is exactly the same and I would have had to set the tps and I found it easier to bolt on the mark viii piece.

Looks sinister, good choice on the color. Is that paint or powdercoat ?

You need a block off plate in place of that egr valve ? I should have couple of them here.

Yes I do. And it's just engine enamel for now. I think I'm going to have it painted properly when I do the engine swap in a year or so. It turned out ok, but didn't lay out as smooth as I wanted, so when I repaint it I'll make sure it's a deep high gloss black. But the egr block off plate would be wonderful. Do you know what size fitting I need for the egr tube? I was trying to make it functional...but I guess that's not going to happen. But now that the check engine light is on I almost have the wife talked into a SCT tuner.
