The filament is in a different location/orientation in a 9004 vs a 9007. Since the reflector is designed around a specific filament location, you aren't going to gain by switching from one to the other.
Assuming you do a ceramic socket and use the relays, you could run an uprated 9004 bulb in your H5s, although there will be more light scatter than with an H4.
I got in touch with the next ten people on my list and - Snowpocalypse aside - will be mailing out kits Monday morning. Seems I've depleted Porsche USA's stash of relay bases and I'm now waiting on some from Germany. Thanks for your patience as these come to me.
BTW if anyone doesn't have the required crimper I'm happy to sell my old one as I upgraded as part of this project. $30 on amazon, I'll throw it in with the kit for $15
If anyone is looking to go a bit upmarket - I did a bunch of research on crimp tools and found a system/brand I wasn't familiar with but like a lot. Pressmaster (of Sweden) offers the MCT which is a parallel ratchet action crimp tool that has many many dies. The frame itself is quite reasonably priced. The dies range from medium to insane price but they too are class acts. They have dies for weather pack, power timer, open barrel, ferrule etc. Waytek doesn't carry the full line but they have the most common ones.
I've shipped out the ten kits for which I have parts for and ordered parts for another dozen which will cover all those who have expressed interest to me but haven't been served yet - about 9 of you. If anyone else wants to get in line, PM over your email and shipping address and I'll add you to the list. I'm hoping to have parts in from Porsche Germany in ~2 wks and will then be able to ship out immediately.

I believe this includes me, and I am pretty stoked about that fact.
Yes Sir you are on the list. And for the record I once owned a SR20DET powered Fastback. I was younger and a great deal stupider and managed to blow the engine on the way to Long Beach Airport to pick up my then GF now wife... we were gonna road trip home to CT. Oh well live and learn
Ok, sorry to sound like an idiot. Just trying to figure out what this kit does?
So I have an H4 kit ready to install, just need to get the trim rings painted body color. I bought the H5 to H4 adaptor from Pelican Parts. I figure yours is a superior option, but what is the main difference between your kit and a pelican adaptor?
Using the PP adapter (which I used for a year) means the factory wiring scheme with no relays remains. Porsche used relays for most high amp circuits but not the headlights. Stock, headlight power runs unfused from the battery to the ignition switch to the headlight switch to the fuse box to the headlight buckets, all using 1.5mm2 aka approx 16ga wiring. This means the full amperage of your headlights runs thru all those components and that the wiring is more or less at its limit and wattage can not be increased safely.
Common practice for high amp circuits is to use a relay thereby keeping current out of the switches, reducing the length of the wiring and allowing you to pick the size of the wire from the relay to the headlights. My kit adds relays and uses 14ga and 12ga wiring for low/high beams and a ceramic socket.
Net result is less stress on expensive switches and more safety margin should you choose to increase headlight wattage. I myself am running 80/100w H4s.

I installed the pelican adapter 10 years ago and stuck a set of h4 buckets in my car. I had always intended to install a relay kit. Another rennlister way back then had made me what was, at that time, about as plug and play a kit as could be....it came in a little box. Had some instructions. I was very grateful to him for having made me that kit.
But- it was a rats nest of wires. And though for an electrically savvy rennlister, maybe it would have gotten installed....but that's not me. I'm just not an electrician, for a lot of very good reasons. So it sat on my shelf - uninstalled.
Anyway- long story short- i have always used the stock h4 bulbs. They function.
With this kit, i will worry less about a future electrical failure, and should i decide to go to a higher wattage bulb, i will be able to. That is the reason we all need to install a relay.
What i find shocking here, is how much thought went into this kit. And how cleanly it can be installed. There have been a couple times i have been impressed like this...once w the abs tester for the c2 and then for the C4....and then those disappeared and are no longer made. And now this.
I'm not going to miss this one.
Wish the C4 abs unit was back in production. Can't have it all.
