i use the h-4 HIDs in most older porsches, my web site is under construction and has a new name. soundfx-ny.com

H5s have replaceable bulbs. I have some PIAA ones in mine. IMO it made my lighting bearable, but nothing great.

Hi:

PIAA bulbs are nothing to write home about and the connector on H-5's truly limits the current draw for any big-bulb potential.

Try the H-4 assemblies and you will be stunned at the difference. Its well worth the investment.

I ordered the H4 Bosch today, thanks.

How about some more info on that HID conversion...where to buy parts, what to buy, etc? I have an '87, which I guess has the H5s.

I used a Painless wiring H-4 relay kit from Summit Racing and it works great! It has a relay for the low beam and the high along with a power relay feeding the low and high relays. Nice quality and the kit is around $80. That and a adjustable voltage regulator, some 90w/100w Phillips Narva bulbs, and Cibie E-code lamps and I was amazed at the lumen output! Search the 924/44/68 boards and you will find a ton of information.

It seems strange that Vertex is selling the H4 for $275 a set and the H5 for $475 a set. Latest Excellence ad.

Set of H5 with new armourfend will be coming up for cheap soon as well as flag mirrors with black bra, the car is Grand Prix white.

There is a company named 928 that is selling an H-4 direct replacement kit for 911/930 sealed beam headlights for $99 on ebay. It includes the lenses, two 50 watt bulbs plus the reflector body. I asked them about H=5 replacement but have not heard back yet If you want to see them search under the name Porsche 911 turbo. After you get there, add headlights or H-4 to the search.

convert over to H-4 bulbs and get and h-4 hid kit. Then you will have all the light u need. you can buy the kits at any highend car audio shop. All the money you are spending on high wattage bulbs and wire harness for a couple more dollars you get the HIDs and there is no substitute.

Hi Steve,

I like your idea of installing 10 g wire, 30 amp relays and the H-4 units. Why replace the H-5s? I'd like to retain the original H-5s in my '87 911. Is that OK? Thanks in advance.

That's it!
I'm doing the upgrade on my car. It has H4's stock so I'm adding the brighter bulbs (80/100), 12G high quality wire, 2 hella relays, and shrinkwrap galore...
I'll post pics when I'm done later today.
