I measured last night - the OD for the PS lines is 3/4"

Sent you a PM.

Looking to get some heat wrap for my power steering lines near the headers - what is the outside diameter of the PS lines, so I know which ID to buy for the wrap?

I saw your article, Wayne, but it is unclear which hoses you cut - maybe it will make more sense when I get in there and look.

I just got the kit last night, but from what I've read and haven't tried it, the hoses in a Boxster are a smaller diameter than the hoses in a Boxster S or 996. The hoses in the third radiator kit have 996 part numbers, so supposedly they are are bigger.

If you haven't had an issue, hopefully I won't either.

You don't by chance have the part numbers of the hoses in the ones you have done, do you?

For those who have added the third radiator to a base Boxster - what have you done about the different hose sizes? I see that some people put copper reducers in, others just tighten the hoses down despite the difference.

What's the preferred/easiest method?

Had an issue for a couple years now - when I turn my HVAC all the way off (zero bars) it will make a click click noise. As long as I don't turn it all the way off, everything works just fine - I can run the fan, etc.

Any ideas? How tough a fix is this?

47K - I'll have them look at the guides when they are doing the IMS.

It sounds like they have to take the covers off anyway, so not a big deal. I'm just hoping the plastic pieces stayed in the valve cover.

I have my 99 3.4 sitting on a palette waiting to get swapped into the Boxster, so I thought I would change the plugs and tubes. A couple of the old tubes (one on each side, of course) cracked while I was trying to take them out, and I'm afraid a few of the plastic pieces got into the valve housing.

I am taking the engine down to have the IMS upgrade done - do they have to remove the valve covers to do that? If so, then I'll just have them clean out the plastic when they do that. If not, how tough is it to remove the valve covers?

Anything else I should do to clean things out? Maybe flush some oil through and see if any of the plastic ends up in the sump?

Getting into buying parts for my 3.4 conversion, and I'm down to either using a FabSpeed or NHP exhaust system.

Fabspeed is about $3K, NHP $2K. NHP claims that there is less drone than other exhausts, and anecdotal evidence on the Internet seems to confirm that. So, I am leaning towards the NHP.

Does anyone on the Board have experience with either one?

Can someone explain to me how, at operating temperature, a low temp thermostat is better than a regular thermostat? Once they are both open, there is no difference in coolant temperatures.

I've talked to a few race shops, and they say that if you are having coolant temp issues, installing a third radiator helps a lot more than the low temp thermostat. All the low temp thermostat does is open sooner, which therefore takes the engine longer to get to operating temperature (which is not necessarily a good thing). You might get a few more minutes of "cooler" coolant, but I doubt that affects longevity much.

I've got my 3.4 engine sitting on a palette in preparation for putting a Boxster. Since the AOS is right out in the open, I figured I'd change it.

Do I need to get a new upper tube, or can I use the existing one? The reason I ask is that, at a couple points, the tube is "wrapped" with a few other tubes.

Any DIY on the AOS for the 996?

This summer, I'll be swapping out my 1998 2.5 for a 3.4 996 engine. The 2.5 only has 42K miles, and I have every service record since new. I will be looking to sell it in the next few months. I'm actually shipping my new engine down from Toronto, and shipping from there to here was only $300.

My guess is that buying a used engine would be cheaper than having yours rebuilt.

PM me or email me if interested.

I'm about to swap a 3.4L 996 engine into my Boxster and I'm wondering what changes/improvements to do while the engine is out. I figure at least plugs and a poly belt. Any other suggestions? Is it worthwhile to swap out the AOS? How about oil baffles, as I plan to use it on the track?

Are the gears stronger? Any other parts stronger? Would there be a way to rebuild a Boxster transmission with the stronger components that a 996 has (not the actual components from a 996, but do they build stronger Boxster components?)

I've read on a few websites that the pre-2000 996 and pre-2000 Boxster transmissions were, with the exception of the ring and pinion and the extra gear, essentially the same. Is this true?

someone will have the pointer that escapes me at the moment.

Here is a link the article about why putting 3.6s into a 2.5 is so tough:

I am getting very serious about putting a 996 3.4 into my 98 Boxster - the only issue left is finding a good engine.

Obviously, the best option would be to buy a crate engine from Porsche, but that runs around $12K plus core.

I talked with Jake Raby, and the only engine they have is a high-mileage one. I'm ideally looking for one with less than 50K miles.

So, I searched car-parts.com, and there are number of engines out of wrecked cars for sale on there. However, I have no idea about the history of these engines, or if they were damaged in the accident, etc. The upside is that the engines are pretty reasonable, with no core charge.

Ideally, I'd like to find an engine that was rebuilt by a reputable shop (like Raby). Second best would be to get a low-mileage engine from a known source.

Anyone have any ideas on this? Any shops that people have worked through that would be a good source for an engine?

Have you first considered the rules restrictions on modifications placed by the organization that sponsors the track events you plan to run? Doing something to change the stock characteristics of the car can place you as ineligible for the class where most other Boxsters are running.

It can be as much fun to see how well your car can do driving against people with similarly equipped cars because then the driver is the difference and you focus on having to increase your skills in order to do better against them instead of just throwing $ at making the car be the performer.

I have no plans to go racing with my car - it is, in my eyes at least, too nice to turn into a racecar. I do plan to do DEs with the car, but I could care less what group or class they lump me in with.

The only thing that I feel that my car is lacking now is power - if I install the 3.4 engine, it would be perfect, and I would plan to keep the car for a very long time.

Next question - if I bought a Dansk header for a Boxster, would it fit the new engine?

What brand of cats and headers did you use?

Still trying to line up the details for putting a 3.4 engine into my '98 Boxster, and I thought I'd ask the Board - which additional parts (and what brands) should I buy for the conversion?

I know I need a new clutch, and it's probably worthwhile to get new headers/cats as well. How about a new muffler?

This will be a street/track car, so I don't want a racing clutch, but I would welcome other opinions.

I just bought a Longacre lap timer, and I need suggestions on how to mount the receiver. It needs to be on the drivers side, and I run with the top up and the windows down.

Anybody have good ideas?

Nevermind.

I'm looking for the part number of the connector on the end of the seat belt receptacle. On the driver's side, it is blue, about half an inch square, with four pins. I was looking at the parts diagram, and I think the correct part is 999.650.225.40. Could someone confirm this? Also, is it the same part number for the passenger seat?
