  1. Welcome to RennTech :welcomeani:

    There is a sensor for the air bags under the center console that measures rapid deceleration, triggering the bags.  Most likely, when the car was driven without the console reinstalled created this issue.  I would have the code read and then cleared with a Porsche specific scan tool (disconnecting the battery will not clear it, it has to be done with the correct scan tool), and then drive the car to see if it comes back.  If it does, wiring is not connected correctly; but I would be willing to bet it won't come back.


    Good luck.😉

    I am only considering the short block.  All the Variocam stuff is in the heads, which I am reusing (after a refresh) from my M97.

    I believe the M96/03 is from 2002-2004, and would be a 3.6L.

    The question is whether this block would work with my 3.4L heads if there are any other complicating issues.



    Sorry, but the 2002-2004 Boxster S engine was a 3.2L, not a 3.6L.  later models got a 3.4L engine, but there were no 3.6L M96/97 Boxsters from the factory, although there was a 3.8L 9A1 engine in 2015-2016 "Spyder" model. You can interchange 3.2 and 3.4 cylinder heads within certain bounds and caveats: Both engines need to have the same cam drive systems (chain styles and number of chains varied over model years).

    I snapped a rod bolt in my '07 Cayman-S (a "money shift") and I'm looking at replacement options.

    A local shop has a brand new short block, but its labelled "M96/03AT" - which I think is the block for an early 2000's 3.6.

    Would this work with my heads (M97, Variocam +)?  What would be different?

    Is it correct to assume that a newly remanufactured factory motor would have the latest IMSB?

    The price makes it very compelling but not if I have to do a bunch of work arounds to get it to work.



    Your engine is a VarioCam+, a 2000 engine would be a 3.2L  and carry the earlier VarioCam system.  Which IMS is in the engine would be determined by when it was rebuilt, 2002-2004 it would be the single row serviceable bearing; 2000-2001 could go either way, any earlier and it would be the dual row serviceable bearing; 2005 or later would have the oversized non serviceable bearing.

    Can the front hood be popped and left unlocked over the winter months Or will it kill the battery?


    It doesn't need to be left open, simply buy a quality battery maintainer like Ctek, plug it into your cigarette lighter socket, run the cord out thru the cut out in the bottom of the driver's door (there for this exact purpose), and let the car sit for months (locked with the alarm on) without any issues.

    Probably stupid question but where is the engine number?  I have 2000 996 with 58K miles and am trying to determine likelihood of dual-bearing IMS.  2000 was the transition year.  So thankful for your help.  


    Welcome to RennTech :welcomeani:


    Unfortunately, as noted above, 2000-2001 were transitional and could have either a dual or single row bearing.  Equally unfortunate is all the internet garbage about being able to determine which style bearing would be in an engine of this vintage from engine numbers, VIN, production dates, phase of the moon when the car was built, etc.; all of which are complete nonsense.  The ONLY to know which style is in the engine is to take it apart and look.

    I put the car on the lift and removed the belly pans...  I was hoping that would find the source of my stinky gas smell once the belly pans were removed.

    Nope, no stains on the belly pans and no wet hoses.  So I guess the next step is to check/replace the fill pipe check valve and or the charcoal canister.  Can anyone tell me if the check valve is stuck open will the car run fine and could be the source of my gas fumes...


    If there's a problem with the check valve will it show up on my Durametric program?




    Unless something codes, Durametric won't see it.


    Before ripping the car apart, open the front trunk, remove the battery cover, and have a sniff about; we haven often see problems with the top area of the fuel pump assembly involved with gas odor issues.

  7. That is entirely your call.  You will need to change the master cylinder over to provide brake fluid for the clutch system, pedal set, run new hydraulic lines from the clutch pedal to the clutch, shifter cables , shifter, electric switches for the clutch cruise release, back up lights, reprogram the DME (it will be looking for the Tip and will code without it), etc., etc..........  And when you are all done, the VIN will still say it is a Tiptronic car, lowering any resale value.

    Yes, I was just hoping that LN Engineering may have come up with a different line to clear larger bars. I hate to purchase a sway bar set and find out I have clearance issues.

    Thanks for the response.




    It isn't the line, it is were the fitting exits the bellhousing.  The line is flexible and can be moved, the fitting's exit position is determined by the flange on the rear of the IMS shaft, and cannot be moved.

  9. Depends upon the size and shape of the bar; the 996 sway bar is close to the Solution fitting coming out of the bellhousing.  I'd suggest you measure your clearance with the factory bar in place so you know what you have to play with, and then look at the diameter and position of the bars you are considering.  From experience, some clear and some do not, even when they are from the same manufacturer, so it is a bit of a crap shoot.  Another idea would be to contact your local PCA to see what others have had success with.


    Good luck with this one.

    I have a 97' tip Boxster with a blown front seal and unfortunately, I broke the clutch basket on the axle while trying to remove it from the case (**** YouTube tutorials, didn't think it through). I was planning on replacing the bushing and seal with the oversized one and getting my oil pump machined so that the bushing would fit.... But now I have broken even more parts in my attempts to fix it. 

    SO! I have a parts car that is a 98' manual Boxster. How realistic is a conversion from tip to manual? I would be doing it with the help of a few friends.


    Auto to manual conversion attempts are a fools errand.  You will need to literally tear the entire car apart to do it; parts, even out of the junk yard, will cost way more than the car is worth.

    I confirmed by using, as well as a reputable Porsche indie, the Pentosin CHF 11S works well without issue.  Also Pentosin CHF 202 works well if you cant find the 11S.  A friend whose had his 911 cab much longer than I uses John Deere trans/hydraulic fluid and it works well.

    Amazon carries CHF11S in stock.

    Your correct the buttons on the key remote are used to unlock and lock along with trunks are working fine. The Key starts ignition fine but it won’t open the door. 
    Thank you JFP. 

    The car's keys should match the ignition and door lock mechanically, and the obviously do not.  Problem is that Porsche uses a very unusual key type, so I do not think re-keying the door lock is a practical approach, and you will end up replacing both locks to get everything to match.

    I will assume that when you say that opening is done with the key that you mean it is done using the buttons.  If that is the case, the immobilizer is working, but not the key.  Probably at some point, either the door or the door's lock was changed, which is why it no longer matches the key.  Unfortunately, the answer for this is going to be pricey, as in order for the key to work the door, the immobilizer, and the ignition, you will probably end up having to replace the door and ignition locks, keys, and reprogram the car to accept the new keys.

    Yeah, I've read all about it. This one came from Hemet CA in the dry heat and didn't get driven for 4 years,,The CV joint is fine.Tight and no knocking..It's a pricey replacement just for a boot..I'm still searching for a split boot..

    Didn’t use a split boot, that is asking from trouble; pull the axle and replace it with the correct part.

    Anyone have any experience with using CV Split Boots on a 03 986 and know of a source to get them? Good,Bad or Indefferent?

    Common Boxster problem, worse with the S model due to axle shaft angles.  Boot replacement is also a common, if messy, DIY project.
