But I do know that you can run into issues with the top when running a wing.

If you're set on gluing the bumper at least use the correct adhesive.

I would say this devalues the car and your money/investment here is better put into another area such as wheels, tires, suspension, engine mounts, maintenance or even fixing those engine lid struts would be a better use of your money.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Good for you! Are you trying to buy that specific car, or is that just a random pic you found online and you're looking for one specced out like it?
From what I can tell that is a C2 cabriolet, with a C4S rear bumper conversion and 996.1 aero rocker panels.
I'm not a big "leave it alone because Porsche designed it that way" guy, but the C4S rear bumper on a Non C4S plus the thrown on rear emblem is a bit of a no-go for me. She looks like she has a little bit too much booty in the trunk.
It won’t fit, but what’s the point anyway? The car already has an aftermarket C4S bumper. I don’t think it will look better will a red turbo bumper that doesn’t fit properly.
With some work....actually a lot of work...you can make the turbo bumper fit.
I think the one pictured is nicely done.
Don't worry about if it is "factory" or not.
Design/build what YOU want.
The same people who tell me my car looks bad because it "doesn't look like it did when it left the factory" then tell me how brilliant Magnus Walker is because he designs aircooled 911s that don't "look like they came from the Porsche factory."
Tell me my car is ugly, but don't involve the "it must remain like when it left the factory if it isn't aircooled" excuse.
I like my car and that's all that matters.
Even my wife disagrees with me over the black "trim ring" around the headlights.
I'm not a fan of cabs whether they have a wing or not.
But I do know that you can run into issues with the top when running a wing.
Make sure you either use one designed for a cab, or make sure you find out what they do so you can modify a wing to fit.
What I've personally seen is that the 996 Turbo (front) bumpers will fit the narrow body cars aside from the duct work being different; however, the rear bumpers are roughly about 3 1/2 inches wider. I don't think the OP will be happy with the excessive gaps and unusual warping of the bumper.
You could "easily" take out 3 1/2 inches of width by cutting it out of the middle.
I would expect you would have strength issues which could cause cracking if not done correctly.
I like the "air duct" cut outs in the bumper because it looks similar to a Porsche 959, which is still my all-time favorite car.
But I myself wouldn't add them to my car.
Too much work.
Someday I'd like a 996 turbo because it is the closest I could come to a 959.
I considered buying one last year before I found my C2.
I am not doing the bumper myself, lol. After reading some of the responses I was scratching my head and wondering if we had some well... let’s say.....ah IQ challenged folks. This bumper with be cut to fit. It’s polyurethane just like the factory bumper. It will be cut and rejoined using the proper “kit” necessary.
Besides if I decide I want to change this back to factory it only takes 30 minutes to carefully remove the factory bumper. I was surprised. All Phillips head screws that were never removed from my 20 year old 50,000 mile car.
These things need to be approached properly by professionals. I wouldn’t know where to start. I’m not an auto body guy. I don’t mind a little mechanical work here and there but nnnnooooo autobdy work. It’s like electricity in the house. I stay away.
I have them my factory bumper with my new/used bumper. They will match them up well. Once they think we have it we will dry mount it before paint. It’s goint to be great. I’m stokked.
Did I read you right? You said, "it will be cut to fit"? Let the fun begin!!! I'm so subscribed to this thread now!
You must keep us posted with photos. I'm gonna love watching a turbo bumper cut-fitted to a narrow body.
Btw the bumper will be cut if necessary. First it will be dry fit. Then we go from there.
What happened to keep us informed and good luck?
Or maybe I know someone who has done that. Maybe look them up for information.
Sometimes I feel a little negativity on this forum.
I was hoping for Porsche discussions and comrade.
Okay, now I see that you’re putting the bumper on a different car. I misunderstood the original post and thought you were trying to put it on a car that already had that bumper style.
What will you do do with the open vents in the bumper? Obviously the radiator ducts from the Turbo won’t be there. The C4S has decorative covers on the vents. I suppose you could install some of those. I could be mistaken, but I think you will need to modify the exhaust to fit properly in the cutouts of the new bumper cover.
The exhaust does to be modified at which paint I will be doing new exhaust tips. Most likely the double barrels.
I am going to seek reassurance from my body man that when the bumper is rejoined after being cut that it will hold.
I am also considering epoxying some kind of polyurethane pieces on the inside area of the bumper once it’s back home. This is something I can do myself. I am also going to be using black screen to cover the turbo intake openings. I’ll heat it up nice and lay it inside the bumper. This is something I can do.
It would be good if they took any cutout pieces and used them inside to support the bumper.
That might make it where you wouldn't need to support the inside.
I'd be interested in knowing if having the non-blocked off vents and screen reduces heat in the engine area.
With the heat shield so close it might not make a huge difference, but cooler air is cooler air.
Looking forward to seeing how it looks.
See if you can get some pre-paint pictures so we can see what it looks like before it is covered up.
Wow, trying to follow what is actually happening here is a struggle. Sorry OP but you're not doing a very job of being articulate. I had to look at some of the other threads you've started about bumpers to even figure out that you have the car already and you're just trying to fit a turbo rear bumper. I see some subsequent posts here where you made it more clear. Half the people that commented negatively did so thinking you were talking about rebadging your car - because that example you posted has numerous modifications other than the turbo bumper.
You can't epoxy polyurethane.
If you're set on gluing the bumper at least use the correct adhesive. 3M DP8005 is what you need. This is the adhesive that manufacturers use for polyurethane/polypropylene and the other low surface energy plastics.
***Negativity Alert!***
I would say this devalues the car and your money/investment here is better put into another area such as wheels, tires, suspension, engine mounts, maintenance or even fixing those engine lid struts would be a better use of your money.
Mods (if you even want to call this that) like this are what gives 996's a bad reputation.
"What will you do do with the open vents in the bumper? Obviously the radiator ducts from the Turbo won’t be there. The C4S has decorative covers on the vents.

Those ducts behind the rear wheels are not "radiator ducts"... The radiators are in the front of the car... I believe the turbos sit behind the rear wheels and these vent help to keep them cool.
Actually they are radiator ducts.
The duct opening is in the rear fender, just in front of the rear wheel. This duct channels air to the radiators for the intercoolers. The air exits through the vents behind the rear wheel.
So, they aren't the primary radiators for engine cooling, but rather smaller radiators for intercooling purposes.
I found a great cutaway image online that shows these ducts and the rear radiators very well. You can see the black ductwork above the rear wheel, as well as the radiator/intercooler.
Really highlights how much wider a turbo/C4S is than a NB C2...
Interested to see how this pans out - would it not have been easier/cheaper to purchase an aftermarket turbo/C4S look bumper for a NB than try to modify a real a turbo one? Either way keep us posted!
Yeah, but the ducts for the inter-coolers are in front of the rear wheels... the ducts invthe rear bumper were cooling for the turbos that sat behind the wheels
I agree with this statement. There are turbo-like bumpers from companies like Duraflex that will match up to the narrow body car for proper much less money than trying to cut or modify a bumper that was made for a car that's 4 inches wider. Here is a link:
