I picked up a turbo tail for my 97 C4S.

Any suggestions before tacking this project:

- tips?

- additional hardware needed?

- potenital issues to deal with?

It is a very easy swap.

- Unplug the spoiler wiring inside the engine compartment (on the passenger side, just follow the harness from the decklid)
- Remove the 4 bolts holding the decklid to the hinges (be careful not to drop the shims into the engine bay if they are present)
- Align tail to the hinges and start putting the bolts in (if you do not have the hook for the latch on the new tail, you will need to remove it from your existing decklid)
- Check alignment and see if you need to use the shims
- Unplug the spoiler control module in the passenger side footwell (there is a screw holding this in place if I recall correctly)

The whole project is about 10 minutes to an hour, depending on the time you take to enjoy your beer and time spent fiddling with other things in the engine bay...

I've read that you need to unplug the spoiler module plug under the dash to
avoid the spoiler malfunction light on the gauge cluster.

**EDIT: Ha, sorry, my post took so long to post and someone already gave a far more comprehensive answer!

Here is a step by step:

Ask whomever you bought the turbo tail to let you send it back
Look for a split grill off of a C2S
Paint to match

I just installed a turbo S on mine. Those things weigh more and my poor old tail gas struts can't handle it when opened. I can't find a part number in PET for a "turbo" gas strut so I recommend you may want to get a set of fresh struts to handle the new weight.

BSL

Could there be that much weight difference between the Turbo and the Turbo S tails? My Turbo tail seemed to be lighter than the steel decklid...

(I may note that the Turbo tail currently resides hanging on the wall in the garage...)

Good question, don't know if there is a weight difference between turbo and turbo S tails. My guess would be that the Turbo S is heavier. That wing assembly part on the S tail is beefy and would probably account for any additional weight over the turbo tail. My struts are probably near shot anyway as they could barely handle the split grill stock lid.

Qucik rennlist search shows:
Motorized tail: approx 25 lbs
Turbo: approx 22 lbs
Turbo S: approx 33 lbs

Have to disagree there! Love mine on my 4S. What is truly useless in application but looks cool are the GT2 splitters with the Turbo wing. Front end needs WAY more downforce at speed. Looks great if just cruising, but not good for track or high speed driving of any kind unless you enjoy front end float!

there is also a different air box snorkel for the fixed wing, to help bring in some outside cooler air since the air under the wing actually gets warmer if I recall correctly.

That snorkel is a terrible piece! Totally starves the NA motor, I had one and promptly removed it. Removing the standard intake port and leaving the box intact is the way to go and free

I have had a 993 Turbo snorkel on my car for 10 years....my bone stock motor just pulled 255 HP on the Dyno...

Well almost bone stock, 200 cell cats, X pipe and modified mufflers + Da Snorkel!

I would recommend finding a used decklid and have it painted at the same time you do the tail. Remove and retain your current lid. Mount your turbo tail on the other lid. You can always get your money out of the extra lid and if you don't like it and I believe it sells better as a complete unit. I purchased a aerokit wing already on a decklid and when I disassembled it for painting there was marking all around the decklid opening where the grill goes. I'm not sure how the turbo tail overlaps the decklid, but you may find that if you decide to remove the turbo tail you may have damage, rubbing on your decklid that will require some attention. You maybe able to check the fitment before you mount it and make sure it won't be rubbing anywhere.

Chris - can you explain how you arrived at this conclusion?

Butt meter at the track with and without snorkel
Plus it has a bend in it and pinches down to a much small diameter than without. If you consider taking the snorkel and/or the original trumpet out of the air box completely, you get the biggest open area for air intake. Considering I could put my hand on most any part of my motor even after a hard track session proves that the air under a fixed Turbo wing (orig or aftermarket) tends to remain more than cool enough for motor operation without the need to choke the intake with the snorkel.

Scientific proof...........nope
