Thanks for the warm welcome. I was about to post a reply when my F-ing computer shut down. POS! Anyway. I was able to figure out how to get the BBS to auto notify me when a post to the thread occurs, now how the hell do you get that box to wrap around someone's previous comment? I wanted to comment on mueller's ebay Boxster trani and engine deal! Couldn't you have let me thought I got a good deal for a least a week or two?
As for the scrapping of the rear suspension. Yes, that is the plan, the question is what to replace it with. Brad suggested using the boxster susp to me last week, and I'm open to it. The simpler this project stays the more likely it'll get done before I'm laid to rest! I too was concerned about the width of rear susp of the boxster but changing the length of the control arms might also be an option. I need to look under there and see what's going on with the geometry.

Jeroen: How can I get a hold of the parts list for the engine and trans? I need to order some fasteners.

Oh.. 2.5 engines/tranny's are worthless. They can be had for CHEAP. You will not find a better deal on a BoxsterS engine than what you found. Promise

B

OK guys, here is another question to add fuel to the fire...
As we have all seen, Brads sig at the bottom of his posts says he wants to build the first V8 Boster.... (at least at one time it did).
What is the feasability of using the Boxter tranny with a
SBC in a 914?
Thom

The BoxsterS 6 speed would work fine with a SBC. Problem is: KEP isnt even considering an adapter for it (yet). I called them early last year asking them to get started.. I buy a lot from them and they still told me "no thanks".

Now the reason why the 6 speed would work:

The problem with the 986/996 engines is the fact that the starter comes in from the engine side and not the tranny side like a air cooled Porsche engine. This is OK for the V8 because you could run a stock GM starter against a flexplate flywheel. Jaidecar did this back in the day. They used a GM automatic flexplate with a flywheel (no ring gear) mounted to it. Pretty simple. The whole reason I had the BoxsterS 6 speed was to figure out a way to run it behind air cooled Porsche engines... then WEVO released the setup for the 915 mid engine.. so I dropped it.


B

Brad,
I'm sure that between yourself and a few of the talented unnamed regulars here
that an adapter plate could be put together....
TE

First person with cash in hand..LOL

The cables and shifters are pretty cheap.. the length of the cables is correct. The shifter assembly mounts on TOP of the center tunnel wherever you would like it as high as you would like it... We already know how to do hyd clutches.

Oh.. the BoxsterS box is a true cable shifted from the factory box.. the other Boxster boxes use a "monkey motion" linkage setup connected to a shift rod like a 901/915/930 (they are not TRUE cables shifted boxes) The S box has two arms on the side of it. Connect the cables and run.


B

Man! Now I have to wait to see what you guys do. If you can pull off an affordable conversion I might consider dropping my Boxsters 2.7 and upgrading to a 3.4. Then put the 2.7 in the 914. Two for the price of one and half.


Found this picture of Boxster on slicks:

Shouldn't be too difficult. You could use the original throttle pedal assy or just adapt it's potentiometer to the pedal in the car. Six or so wires the ECU and your flying by wire. For OBD you need the ability to scan the ECU for running/performance DTC's but many of the OBD2 components/systems are not needed. The secondary air and canister purge stuff can be left off and the fittings capped. When you scan the ECU the faults will be stored but running will be unaffected. Likewise the cats could be gutted, the rear O2 sensors will set a cat efficiency code but so what. I doubt you'll be hooking up a check engine light.




I think this may be the bigger problem. The immobilizer system has a few more components, the read coil around the ignition lock and the key with a transponder. When the ignition is switched on the immo system looks to see that the key is one that has been adapted to the car while the system was in a password enabled learning mode. Someone can "dupe" you key and open the door but the engine won't run. You either have to wire up and tuck away all the components or find a way to "unlock" the ECU without the immo stuff.

Jason,

both the Boxster engine and transmission had "issues"...and about 80k miles (hard from what it sounded like talking to the owner)...

the only reason I wanted to transmission was to do some research on a few things (SBC and our aircooled motors)....for a few hundered bucks, I thought it would be great deal for R&D and it wouldn't hurt too bad if it sat around for a while.

You got a killer deal and one that a lot of Boxster owners would have loved to get to upgrade thier older Boxsters.

One good thing for us (conversion-perversion folks) is that I don't see too many early Boxster and early 996 guys wanting the newer motors with the E-throttle....too much work for them, it's not a true bolt in procedure for the non-E-throttle cars....which means more motors available for us

Thanks for clarifying Mike. Actually I wasn't too worried about the whole Ebay thing, I was F'ing w/ you. Hell, I'm still in the euphoric state of 3.2L ownership! Each time I step into my garage and look at that engine I get wood.

Anyway, as for the E-Throttle you are all talking about: I already have the throttle pedal itself (essentially a plastic pedal with a cable attached), and the guy I bought the engine from (Chris) will be removing the poteniometer from under the dash in the next few weeks. The cable from the pedal will attach directly to the poteniometer, and from there it's all elecrical wire back to the engine. It should be a plug and play sort of deal.

It's pretty ridiculous if you stop to think about it: 914 Chassis, Boxster motor, Boxster Trani, Boxster shifter, Boxster throttle, Boxster rear suspension.... I wonder if Chris will sell me the interrior!

Since I can't seem to add more than one picture per post:

And one more:

For those worrying... that's a LIGHT beer

cheers,

Jeroen

It was Amstel light.. I drank them all...LOL Great shots Jason. I figured they would surface sooner or later.


B

See, I'm not totally worthless!

For those of you who were worried about the immobilizer unit on the engine: I spoke with Chris yesterday, and he has already obtained the codes from Porsche. Apparently there are codes for: The engine, the Nav system, and the radio. In order to obtain any of these codes Porsche requires proof of ownership of the vehicle i.e. copy of pink slip. I guess Chris put in a request for all of these codes some time ago. Brad later informed me that Porsche will also release these codes to shops, so it sounds like we have our basis covered.
Oh and for those of you interested: Chris is selling the Radio and Nav System too! **914 with a Nav system?**

Now on to the next hurdle.

now -that- would be useful ! something to tell the AAA operator -exactly- where you are when you need that tow !

Haahaa!

Or more importantly telling the State Farm claims adjuster where exactly the charred remains can be found!

Silver Bullet:

Just came across this thread and some photos. I have been looking
at using a boxster tranny in a 914; but looking at my boxster tranny
photos regarding the "starter pocket location" and your engine photos
I am confused ! Your starter is mounted on top of the engine which
leads me to believe teh tranny starter pocket must also be located up
there !. BUT my boxster tranny (1998 five spped) has the starter
pocket on the lower passenger side about 2" below the centre line of
the crank, nowhere near the top of tranny.

Please confirm if your tranny in the photos is a six speed or out of
another model 996 etc. Thanks and must appreciate your pending
reply/info.

that is due to the transmission housing being used on Audi engines as well...not sure if it's for the inline 4's or V6's or V8 models....

what motor are you going to mate that transmission up to?

I'd like to see the modifications or adapter if mating to an air-cooled engine (/4 or a /6)

some guy in NJ posted a week or so ago with the red 914 with the boxster transmission, forgot what motor he was using though.

3.2 I believe...payed mega-bucks to the shop to install it.....$10K+ just for the install (lot's of fabrication and R&D)

OK, attached is a photo of the Tranny for your consideration and replies.
I got the info from a friend that confirmed it was a Five Speed from a 1998
Boxster 2.5 or 2.7 L. After looking at the tranny case and the numbers located
on it indicate it's actually mfg. by Audi/VW and used by Porsche in their Boxsters.

As you can see when you compare my photo of the tranny to the rear engine
mounting surface in picture listed above these two would definately not mate
no matter what type of adapter plate. Appreciate any comments and replies.

Thanks

Allan

Allan,

The engine above is 3.2 Boxster "S" and came with an "S" 6-speed. Jason and Darren are transplanting the complete drivetrain including rear suspension. Don't expect a response since they don't log into this site often. You may have better luck with direct email.

This tranny thread explains some of the differences so you are correct, the Type 4 will not bolt up.

The guy who had a Boxster tranny installed had a later six..here

the transmission you have will bolt right up to the engine in the picture.......the transmission has multiple thru holes that are not used when mated to the Boxster engine.

When used on the Boxster, the transmission does not need a traditional starter "hump" due to it's location on the motor.(and the size of flywheel, plus other factors)

The "hump" you see on your transmission cannot be used with any of the flat /4's or /6's unless you have one heck of a short starter

You still have not said what motor you want to use. If an aircooled engine, you better have money or access to a machine shop or be a good fabricator

So... in summary...

There are easier and more cost-effective ways of getting the 914 to go faster.

But if you want Boxster performance...buy a Boxster!

I don't know about all of you but it doesn't look hard to mate the motor to the 901 or the Audi trans to me.

if using the Boxster engine, it makes sense to use the Boxster transmission, I think it would be silly to try and mate any other gear box to it...no reason to unless you want an automatic or the audi gearboxes are totally cheaper and can easily be adapted to it.

now for adapting the Boxster transmission to an air-cooled motor, that does seem more logical...I've been looking for a dirt-cheap gearbox to do some R&D on

I have access to a Tip from a Boxster S, but I don't know how much the owner wants for it.....I'm guessing 10X more than what I want to pay, LOL

RICH

Please fin below a Right/Passenger side view of the tranny
and clearly shows the "starter" pocket. Thus looking from the
photo make me think that I could mount a starter within this
pocket area from the engine side; just a thought.

Also I understand that the Cast Aluminum Case could be modified
and possibly weld in a starter boss for mounting a starter, and if
an adapter plate of some kind was used then the start could be
mount to adapter plate, just a thought. Any idea to comments

Allan

Don't work so hard. Use the Boxster starter in it's current location and Boxster flywheel. Make an adapter plate with counter sunk fasteners to attach it to the block. Slide bolts through the adapter plate tword the trans axle side. Use nuts on the transaxle bolts Based on the photo you posted above there is clearly enough material on the belhousing to allow some shortening to get the input shaft back into the pilot bearing. The casting the bolts slide through looks to be 2" long. If the transaxle interferes with the boxster starter trim the bellhousing. Easy..

P.S. I'd bet there may even be a bolt or two that are on the same base circle.
