Love to see the work you are doing with the adapter plate. I am sure it will be getting plenty of use once finished. Both for the Boxter & our 914's. Do you have any interest in doing a plate for the 1.9 TDI motor?


I was under the impression that the VW TDI motors were a direct bolt-on for the 5 speed Boxster tranny... No?

no idea if it is a direct fit, but a question that is almost more important is will the gearing work for you? remember a TDI is going to have a completely different powerband, would suck to go thru all that trouble and expense and have something you don't want to drive due to poor gear ratios

If I were to send you a solidworks drawing of an engine, could you see how well it would match up to the Boxster S six speed?

Prototype motor mount/cradle is finished. It mounts using factory hardware locations, and requires no chassis modification or welding. The bottom of the cradle also acts as a skid plate of sorts since the oil pan sits about a half inch lower than the stock oil pan.

Thats right! I'm getting so used to these dang adapter plates with my v8. I seem to think any conversion needs them (IMG:style_emoticons/default/dry.gif) . The VW motors are very torquey (is that how you spell that (IMG:style_emoticons/default/huh.gif) ) . So the power band doesn't concern me that much. I think stock HP is like 135-145 I think. Once they are chipped & a few mods I think you can push close to 200hp. But the HP isn't where it is at. The torque is sweet not to mention the gas mileage (IMG:style_emoticons/default/drooley.gif) .

Okay back to the suby motor & your adapter plate. Sorry for the slight hijack. Love what you are doing with the Boxter. I've been keeping my eyes open for an older boxter with a bad motor. Mainly to scavenge the tranny & cable shift setup for a 914. Would love to have that mated to my current buick 215 v8 conversion. Be more tempting to just pull the motor & do your Suby conversion. Keep up the good work (IMG:style_emoticons/default/beerchug.gif)

That is a cool conversion. But now I'm going to have too listen to their exhaust beat before I taunt them too much with the teener. I have a water cooled conversion that I've been running a 5spd 012 and Boxster shifter for a few years now, and LOVE the shifting! Rock On! (IMG:style_emoticons/default/aktion035.gif)

sweet cradle : )

love all the photos of the boxster : )

has anyone determined the robustness of the boxster transaxle, realted to a stock 914 transaxle, a 915 and a 930?

does the boxster have power assist steering??

i assume this conversion will have catalytic converters and pass 50 state emissions? or will this be strictly a track car?

no shortening of the oil pan - that will save some time and money : )

Nice work - but make sure it all fits the EZ30R too! Some Boxter owners might not want to step "down" from a 6 cylinder to a 4. The 30R should slot in there just as easily!

Now if someone would just offer a good looking flare package for the Boxter and help it "man-up" a little bit!

The boxster S six speed is STOUT. (IMG:style_emoticons/default/smile.gif) It's the same one as in the Cayman, and an inverted version of the one in the new 911 turbo cars. (whatever number they are doing)

It will very easily handle the HP and Torque of a well built Subie Turbo engine. (IMG:style_emoticons/default/smile.gif)

ez30R and ej20turbo both fit in renegades cradle with no mods. So i bet they will both fit in your cradle too! I love my ez30R.

Wow am I thankful. I was wondering what I was going to blow my money on when I start making some in 3 years (IMG:style_emoticons/default/wink.gif) An EZ30R and an old boxter is a no brainer (IMG:style_emoticons/default/smilie_pokal.gif)

When you pull the pan on the suby motor check the pickup real close as they are known to be brittle from the brazing process at the block flange and the pan definately looks like it's against the pickup. a lot of suby pickups are too close to the pan and when guys jack the motors up against the pan bottom the pickup gap gets real tight and some pickups have broken either from vibration or getting fractured from hitting the pan.

^ agreed, the pan has definately been lifted by the pan and has most likely damaged the oil pick-up. This engine is probably already got spun bearings due to oil starvation.

This engine cradle and tranny adapter looks excellent. You could easily get a ez30r in there with it being less than an 1" longer than a ej257 ect. A built ej257 with a gt35r can crank out over 500 whp/wtq. Most builds are probably between 350-400 whp/wtq. If the porsche tranny can hold up to this, it sounds like one hellofa setup.

Wow.... you do some very nice work and use choice colors. That green on the 914 is sweet (IMG:style_emoticons/default/beerchug.gif) .

I may be in touch in about a year as I have been thinking of getting a Boxter for a daily. Sounds like a good way to go since I already know the Suby engines.
