I'm installing the glass window top from EZontops, on my 99 boxster. So far so good except I can't get the front part of the cloth to stick under the header bow. Has anyone done this, or have any idea what type of glue to use?

Thank you, for your help. How much are you asking on your top, and what color is it?

I need a new top, my plastic window broke in the cold. I want to upgrade to a glass window, and have read a few people like the GAHH top for our models. GAHH has their top listed for $900.00 but I have seen them on ebay new for $600.00, and I was wondering if anyone has bought a top from ebay, and if so what their experience was. Thanks

99 Boxster non S

My AOS (air oil separator) is extremely dirty once again after only a few months after replacing it. Also my rough idle is back. This had been resolved when i replased the AOS originally, indicating that it the AOS once again. The car is a 99 Boxster with a 3.4 996 conversion engine. I believe the AOS was from a boxster and replace with a boxster AOS. Are these parts interchangeable ? Could that be my problem? What else could cause the AOS to get extremely dirty? Thank you for your help.

99 Boxster

5 spd

3.4 996 conversion

Just spoke to Porsche, looks like it's coming from Germany. Thanks everyone. I will consider the plywood. hehe

I think I just found it, however I am concerned about ordering the wrong part again. Can anyone confirm it to be part # 99610621500 ?

Well, my car is extremely low. The reason this is relevant is because I hit a protruding man hole cover and broke an elbow like structure which attaches to one of my coolant hoses underneath the car on the drivers side. All that was left when I looked under was a hanging hose, pieces of the part and the gasket and bolts. It looks alot like the thermostat housing and therefore I bought the assembly only to discover that it didn't fit. I'm attaching a picture to this msg. If anyone could help me identify the part I would greatly appreciate it. Thanks everyone.

Car is:

1999 Porsche Boxster non S

with a 3.4 996 Engine conversion

5spd Manual

Please give model year and exact model.

I deleted your duplicate post - please do not double post.

Sorry about that, I just wasn't sure if I should post it in the main 986 page so that more people would see my question. The car is a 99 Porsche Bosxter non s, with a 3.4 conversion. Thanks

Does anyone know the part number to the hose that attaches to the Thermostat Housing on a 986?

El Paso? I was just there last week for business (El Paso/Juarez). I haven’t seen many Porsche’s driving through town. Do you have a dealer or reliable service center there? I like the area…as a matter of fact, I’m there often.

There are many more qualified people to answer your question than me, however, I do have experience with lightened flywheels from my college days and my high performance VW engine. At that time I had the flywheel lightened to 10.5 pounds and balanced. I also had a 200mm ceramic clutch installed to grab the flywheel (with a heavy duty pressure plate). In addition, I had the crankshaft and flywheel match-drilled from 4 dowels to eight dowels so that the crankshaft would not become oval at the dowel pin area from the torque. So here’s what I do remember, the lightened flywheel allowed the engine to rev on a dime. It was all about getting the jump for the short distance. I went to a ceramic clutch to keep from burning the standard clutch (went through several). I do not recall an oscillating rasping noise from the lightened flywheel. I was running straight cut gears back then (camshaft), so my 2276 with dual 48 IDA’s sounded loud and commanding…and the whining came from the gears and not the flywheel.

You can’t tell if the flywheel has been lightened unless you physically look at it (unless you have the paperwork from the machine shop or mechanic). If the clutch slips it must be replaced. There is not an option there. If your flywheel is fact lightened, you might consider getting a standard flywheel installed unless you’re running the ¼ mile with a ceramic clutch. I personally am not aware of any reason a daily driver would have a lightened flywheel. As a matter of fact, that makes for uncomfortable freeway driving (not smooth). If you decide you want to keep the lightened flywheel, you’ll need to get a clutch that will engage and not burn out. I will tell you driving with a ceramic clutch is not comfortable at all. It’s either engaged or not engaged…again, it’s been about 25-years since I’ve messed with a lightened flywheel. You’ll be shopping for a Boxster clutch and heavy duty pressure plated for your Boxster and not a 911 clutch assembly.

If it was me, I would buy a new flywheel, clutch, and pressure plate assembly (stock). I drive my Boxster like I stole it and I have 152,300 miles on the original clutch as of my arrival to the office this morning.

Messing with Boxster clutch assemblies is not so easy…in my VW days, it was simply unhooking the electrical, putting a screw in the fuel line, and undoing the four (4) 17mm bolts from the transaxle and dropping the engine onto a skateboard. Now those were the days!

Hope this helps.

Thanks Bill I appreciate the info. I was thinking the same thing. To add to the sports clutch and lightened flywheel theory I had the clutch as you put it is uncomfortable, it's either engaged or not, impossible to drive smoothly. I'll be looking out for a stock assembly. Anyone have any suggestions as for where to shop for one? Also what should labor on that be?

I have 3.4 conversion on my 986. The conversion was done by the previous owner. Aside from the engine he did many other other upgrades ie hid kit hr coilovers etc....Among these upgrades was what I was told to be a lightened flywheel and sports clutch. My question is: if this is the case how can I tell ? I was told that lightened fly wheels make an oscillating rasping noise when the clutch is not engaged and the car is in neutral, which my car does. Also I believe my clutch is starting to give out because it slips but only under heavy load. Under normal driving it engages fine. Is that common? My last question is, if I indeed have a lightened flywheel, do I need a special clutch, also am i shopping for a 911 clutch or a boxster clutch?

Where exactly does the resistor go? Anyone have a write up on this?

What are some of the Air/fuel ratio meter's you guys have used. I am looking for one that doesn't rely on the stock O2 sensor. Maybe something that comes with it's own sensor, as I don't trust mine to function properly. Thanks

Welcome ! I think you will find the people here very friendly and helpful at least I have. Thanks everyone. :renntech:

It isn't a 3.5" intake it is a 3.5" MAF housing.

If I remember correctly, you can't tell the difference between the boxster and 996 throttle body with that measurement. They are both the same at the top side, the difference is the Boxster one tapers down at the butterfly.

I have a 3.4 converted Boxster, and i recently measured the throttle body as I was cleaning it. It's my understanding that the 3.4 should have a 3.5" diameter intake and throttle body. Does this look right to you guys for a 996 3.4 motor? Thanks Everyone

Thanks Todd. So what should I be looking for as an indicator that I have the correct throttle body?

Do you have a sound system? I have a fuse on my grounding cable and when that burns out all sorts od funny electrical stuff starts to happen. Check all the fuses you can find. My suggestion anyway.

does your hand brake light come on ?

Sounds like a cracked tank to me, and yes I'm pretty sure that loose hose is a the overflow hose. I'm sure you have heard this before but you may have a hairline crack in your res. tank. Does it leak even when it's cold or only after or during a drive?

Yes I have used Toluene and Xylene but not on the Porsche. I have been doing the race fuel mixture for racing only. When i did use toluene it was on an SRT-4. Felt good and had no adverse effects. Then again it wasn't a Porsche. Has anyone tried Xylene or Toluene on a Porsche?

Bill,

Thanks again for the excellent response I think i might be sold on the resistor solution combined with the AEM meter since all the other options seem to be much less cost effective for possibly little advantage. Do you know if anyone has a write up on it ? Again thank you for your help.

Bill,

Yes I have read that thread. I read it shortly after Todd told me about the MAF housing and so i did a search on the subject and came across your conversation. I like the air/fuel meter idea but i really want to avoid the resistor method if possible because I would like to get in the amount of air that the engine was designed to receive. I will definitely look onto that air/fuel meter. What are the advantages over the one you mentioned vs others? Thanks for your help everyone.

Hello everyone, I have a Boxster with a MY 99 996 3.4 engine conversion. Any way Todd helped me discover why my car has always run rich, which was due to the use of the stock Boxster air intake system that uses a 3 inch diameter MAF housing vs the 3.5 inch used for the 996. Anyhow, I have looked at some possible solutions but am open to any suggestions. Does anyone know what the diameter of the Cayman S and 987 Mass Air Flow housing is? I think this might be my best option. Thanks for your help. :renntech:

Try parking it with the nose facing down hill and see if you don't see what sounds to me like the wrong type of coolant leaking from the radiator located on the corner you hit the curb. I once ran over something possibly furry and most likely hard that damaged my radiator. However when I parked slightly up hill I saw orange coolant leaking from the back of the car near my rear passenger tire. Upon closer inspection I discovered it to be the drivers side radiator that had bee damaged and I believe was causing an overflow in the res. tank. Someone correct me if I'm wrong. Still learning. :renntech:

I was wondering if anyone knows the inner diameter of the Mass Air Flow sensor housing in the Cayman S. I have a 986 with a 3.4 996 engine and I need a 3.5 inch mass air flow sensor housing to get my car running properly. Anyone have any ideas? Thanks :renntech:
