I’ve noticed that the 968 board has slowed down recently so I thought as I’ve got a little time on my hands I’d update on how we (or shall I rephrase that) Beni made the simple oem modification to look like this:
![](http://www.deutschnine.com/rennlist/968-trs-front-bumper-conversion/porsche-968-turbo-rs-front-bumper-00.jpg)
The tools required to do this are as follows:
We started by first removing the front Bumper PU – this takes about 30 minutes and is very easy to do.
Next give the bumper a good wash removing all dirt from both the front and inside and also remove the plastic lower protection mesh.
In the first picture below you will see where we cut to start the modification and then we removed about 40mm of material under the longitude kit before holding in place with some masking tape:

![](http://www.deutschnine.com/rennlist/968-trs-front-bumper-conversion/porsche-968-turbo-rs-front-bumper-03.jpg)
If you look at the second picture you will notice that we removed enough material to ensure that the new enlarged aperture sits centrally top to bottom between the height of the spot light & indicator holes.
Once happy with the visual location we next used carbon fibre to hold the modified cut out section in place. First you need to use the 120 grit sand paper to create a good key for the resin and carbon to bond to ensuring that the surface is perfectly clean.
Note: Even though we used carbon fibre you can use fibreglass and resin to do the modification just as well – It was just what we had lying about to hand at the time!

![](http://www.deutschnine.com/rennlist/968-trs-front-bumper-conversion/porsche-968-turbo-rs-front-bumper-06.jpg)
After the first application of carbon or frp has set, remove the masking tape from the front and the new modified IC vent is firmly in place.
We then turned our attention to the missing corner sections and again used carbon (you can use FRP) to fill in the missing areas on either side of the aperture opening:

With the back now finished we then turned the front bumper PU over and using more carbon built up the height of the new side additions before skimming the modified areas with a thin layer of body filler and flatting down to 640 grit before priming and final paint was added.

Lastly before you mount your new Turbo RS bumper you need to use the angle gringer again and remove about 20mm of the aluminium material from the front bumper crash support bar to allow the bumper to fit perfectly again and the job is complete![thumbup](https://rennlist.com/forums/graemlins/thumbup.gif)
Finaly we are going to reproduce the OEM brake duck verts for the front bumper PU which we featured on both the OEM yellow TRS and bubbles (the back one if anybody is interested:

The tools required to do this are as follows:
- Angle grinder with thin cutting disk or Dermal.
- A DIY fibreglass kit which can be found in most hardware stores for no more than $20 USD.
- Lots of sand paper and wet and dry from 120 grit down to 640 grit.
- A small tin of body filler.
- And finally a Sunday afternoon of free time and patience

It can be appreciated in two aspects. It not only enlarges it, for say an intercooler, but it also makes the lines of the opening match the lines of the fog lights / turn signals. The regular opening is about half as tall; see my avatar.

Finally got around to modifying a spare bumper last night. Using a FEIN-saw, some masking tape, and a tape measurer, it was fairly easy to get to this stage.
I've bought some insanely expensive glue for the job, will hopefully get around to glue the parts together during the week (don't hold your breath). I'll try to use the strip that was removed to fill in the sides in the enlarged inlet. Will update with pictures when I get there.

I've been thinking about finding a good condition bumper to do this mod for about a year. And at some point I'll find a good trunk lid to do the 968 cab spoiler on too. But then again, I know I would feel bad for molesting a stock car. I guess I just need to get into the market for another 968...

Ya know, since I have an extra 968 front bumper cover sitting around, I may have to do this. Not sure I will put it on my 968 but I bet someone would want it. Either that, or if anyone is wanting to do this pm me and you can try to talk me out of the bumper cover.
