Neo914 powerplant mates!!!!, Audi V6 twin turbo likes Boxster tranny Options

[neo914-6]

I couldn't find a Gates hose supplier open today so my V8 project got stalled. I really need to get this car running before Neo914 arrives from WA.

I went ahead and dug out the Boxster tranny buried behind the 914 V8 and got my new jack installed in my engine lift to get the Audi block on a dolly. This enabled me to test mate them for the first time. I knew the patterns were close but I found the alignment pins matched perfectly and most of the other holes as well. The starter pocket matched too. This means no adapter, no modifying the bellhousing, or finding an alternative tranny. The Audi pins had a shoulder but the diameter matched so all I need to do is buy the pins from the Porsche parts dealer and buy the bolts from the Audi parts dealer (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

Here's the B&M shifter

[campbellcj]

Holy crap, sorry to be late to the party but I didn't know somebody was working on a 2.7T Audi transplant!

Have you sorted out all the crazy exhaust and plumbing issues yet? I love this engine but it sure does not seem very "user serviceable" and the stock externals are iffy, at least with anything over stock boost.

[rick 918-S]

Have you done a hieght measurement yet? The Audi pan looks very deep.... (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) Really cool how that bolts up. (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) Your on a roll! (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

Sick!!!!

Love the cable shift...

I will be very interested in this project.... Especially cost factor... (IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif)

Looks like fun, just sitting there.

[mike_the_man]

That is very cool! I didn't realize this was being attempted either. Any ideas on what other motors a Boxster tranny might bolt up to?

Also, does it look like there be any easy way to make the Boxster cable shift work with a stock 914 tranny? I'm really interested in tha cable shift thing.

[neo914-6]

Preliminary measurements indicate I may not even have to cut any engine compartment sheetmetal. Once I get the Neo914 roller I can position them to design and fab the engine and tranny mounts. The bare block will make it easier to position. Then I'll mount the fully dressed engine to figure out the exhaust and cooling. I may fit them in the Chalon car before the V8 goes in... (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif)

The shift cables "should" be the easiest to route. All I have to do is position the shifter.

I envision the cooling to utilize twin boxster rads to maintain the front trunk space. If that isn't feasible I could always use a V8 or smaller rad (modern 6's don't need as much cooling as proven by Chris914N6) (IMG:http://www.914world.com/bbs2/html/emoticons/clap.gif)

I'll use the stock intercoolers and plan to mount them in the flare and fender space ahead of the John Kelly BA flares. A large intake at the formed rocker will feed them.

The exhaust is straight back after the turbos, I plan to incorporate a venturi tunnel design (unproven but at least an interesting detail).

There are alot more new ideas I will try on this car...

Daaaaamn Felix, (IMG:http://www.914world.com/bbs2/html/emoticons/pray.gif)

Did you have a hunch that the engine & trans would mate directly, or is this just the auto gods smilimg down on you in unbelievable fashion.

[Mueller]

that is great news there Felix...I was pretty sure at least one or two of the Audi engines would bolt up...now this is the 5 speed version correct?

[grantsfo]

I'm interested in how much fabrication will be needed to get that Boxster tranny in the right place on the car? As you could also bolt a 3.4 from a 996 to that tranny as well.

There are a growing number of Boxster drivers who have done the 3.4 conversion quite successfully.

It would stand to reason that the new Audi 2.0T , 1.8T, non turbo 3.2 V6would also bolt on to the 5 spd boxster tranny since its shared with the A4.

[Eric Taylor]

Felix - You should do some RS4 upgrades on the motor. Those cars were scary fast (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) .

I'd never put an Audi motor in a VW!

(IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) That is cool... I love the shifter.

How much HP can the boxter trans hold.

ChrisC,
Tell me your Audi sources, I need to find out the deficiencies of this engine. The front to back of the V6 is very short. When lining up the axles, I will still have over 5” of clearance in the front to the bulkhead. Like the V8’s, the servicibility should be pretty good. This ex-track car also has a bulkhead access panel. (My profession is tech support so I believe heavily in design for service)

Chris and Mike,
It was a calculated risk, I posed the question on VWVortex and Audiworld with little response but found the 012 was similar. This cross-compatibility of parts may only be known by a few Audi-VW engineers.

Grant,
Did they do the 3.4 conversion with the 5-speed? I really wanted an “S” 6-speed but noticed too many differences on Jason’s tranny to match to the Audi engine. He has the full “S” drivetrain for his 914 and I would have followed this route but didn’t want to modify the engine bay and rear suspension. I never got to the point of creating a template to check bolt patterns when I noticed the starter pocket is on the top.

Eric,
RS4 MAF is the only part I purchased so far, they are sold for a premium. Do you have any sources or specs, I have limited knowledge of the RS4? I’ve seen other RS4 parts but I need to focus my budget to new design and fab work first. I plan to solicit Audi tuners for upgrade sponsorship after the car is running.

Andrew,
You won’t believe how much this project has escalated but for a straight engine conversion, I’ll share my costs with you and how to avoid pitfalls. A conversion kit is not out of the question...

Miles,
I’m trying to draw only from the VW/Porsche/Audi parts bin to maintain the “modern 914” theme. Maybe I’ll design a four ring Stuttgart emblem with a prancing goat instead of a horse… (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

LMAO Felix..

You could use pine cones instead of the oak leaves, or whatever the heck those are.

Hi Felix
I am doing something similar...
As was said before the engine swaps are...going to explode with possibilities.
5 speed PBoxter trannys are still pricey here, what are they going for out in your neck of the woods? I imagine you got yours thru a contact, but if you needed another? .
1500 - 2000$ easy, no shifter.
I think the aftermarket has really made this affordable to repair, I would like to know if this is true. Have you looked into it? Maybe pass me a link if you have?
I am looking into body kits..
You Rock (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif)

[Eric Taylor]

Felix, Yeah I've looked a little into the RS4 and from what I can see it's just a beast. The biggest difference is in the turbo's, intercoolers, and ecu I believe. Anyway if you wana spec out some euro only audi products check out:
http://www.euro-audi-parts.com/
They seem to have everything for the rs2, rs4, rs6 etc. that you could want. Just thoughts. I've been creaming for an s4/rs4 ever since I knew they existed and so this swap blows my mind it's so cool.

Joe,
Can't wait to hear about yours...

Last I checked Boxster 5's go for $1k to 1.5k w/o shifter. I haven't looked into service, I figure for that price rebuilding isn't feasible. Actually I know a German tech who has all the tools to rebuild them. The 6's go for $2.7k to 3.5k. Best deals are from eBay but have no warranty like the dismantlers...

B&M's go for $200 - 300.

[neo914-6]

While I'm listing costs:

My bare engine cost $600 but had bent valves. It was from the East coast and sat so it had corrosion all over it. Delivery cost as much as the engine itself. My mechanic quoted $4500 in parts (discounted) and labor to rebuild. 30 sodium valve x $60 ea as an example of parts costs. The block will serve it's purpose and them I'll sell the parts or keep them as spares.

On the high end, local Audi/VW dismantler quoted $4500 for a complete running engine.

On the low end, (which I took) I found an Audi enthusiast on Craigslist who sold me a complete engine for $2500 plus a few hundred for the ECU.

There are so many trick parts for this engine... (IMG:http://www.914world.com/bbs2/html/emoticons/drooley.gif)

Felix:

Should be an interesting porject and at least it will all be "German"
I know you had commented in my Project 914-LT1 posting regarding
a BOXSTER tranny and V8 engine. Which is what I am currently completing
in my vehicle.

BTW in your picture of the tranny and V8 did you actually connect them together
or just do a mock / trial fitting to see if they were compatable. We you actually
also thinking of doing the Boxster and Chev V8 combo also ?

Anyway I have attached photo that confirms my setup and what I am currently
doing; hopefully it will be on the streets within a month or two. Keep in touch.
