Still working on getting the new house together, but the other day I ran into another woman mechanic. Like me, her experience is mostly with conventional engines, not flat sixes, but she's knowledgeable. She said to call her if I need help with tasks that are easier with two people. Actually, she's so fascinated by the engine swap (which she called "interesting and ambitious") she said she'd just enjoy hanging out and giving me a hand if I need it. So far I've done everything solo, but I won't turn down help. You know the old saying, "Wrenching loves company."

Opps... too late. I haven't had any problems. 4 on the floor like this boxster or my daily boxster got towed with a dolly from where I bought it to my house.

At first glance, that car seems to need a little attention. Or perhaps it's only lens distortion?

Looks like a 90's Miata with Boxster seats and wheels. Look at the cut-outs in the hood for pop-up headlights. Or maybe a Boxster rolling chassis with Miata body parts. Also, I don't see any sign of an engine between the seats.

Look at this 1990 Miata:

Hi, Al. Those are definitely Boxster Turbo Twist wheels. Which, by the way, are my favorites. If I bought a 986 that had fancy wheels, I'd replace them with Turbo Twists. Hard to improve upon perfection.

I like them too, and I wish I had them because they seem so much easier to clean than mine. Especially that damn brake dust.

That's definitely not a Boxster body, though.

And BTW that front frame is not from a Boxster, either.

A bit altered... :D

Its a boxster. Tubed out with an FD RX7 body on it.

Its got a rotary engine in the middle. (this car retained the factory firewall for the most part)


But back to towing. I've never had problems towing (granted I haven't towed 986's much) I can't see why it would be a problem flat towing.

The countershaft is on the bottom of the trans, and the lube is driving by that input from the wheels. For the same reason you can tow bugs in this way.

The only reason why I think the manual says you shouldn't is because of the floating steering wheel and keeping the key in the on position will kill the battery. I guess Porsche just didn't want to deal with a bunch of warranty claims for dead batteries.

Ah so it's an RX7, not a Miata, as I originally thought. Pretty slick (or sick) LOL. I assume the Boxster engine was grenaded, but what was wrong with the body that you had to transplant another ono it? What's that engine in there now? It seems to sit a lot lower than the Original Boxster engine.

EDIT: Nevermind. you answered the engine question below. But what was wrong with the body?

I don't know what happened to the flat six. I might have been a runner. Don't care I tossed the engine in the trash as soon as the car came to my house.

The skin came from a salvage guy in Florida. The skin looked like it got swiped in the right rear corner. I slapped it on my truck and took it home. Cheapest way to get an FD now a days.

Oh, you mean the 986 body. Not much wrong with it. I cut the skin off of it and saved it for future repair to my DD. As it so happens the RF fender is on my DD now. I used the junky fender that was on the boxsterado on the RX986 (for the fuel door), and swapped the blue fender (resprayed) onto my DD.

What did you have trouble understanding?

The first sentence "Oh, you mean the 986 body" is shortened because I had made a previous response in haste and didn't think about the OP's question regarding the 986 body.

The next sentence "Not much wrong with it." depicts the condition of the 986 body. "It" in that sentence stands in place for the type of car I'm describing, in this case its a 986.

This sentence might get dicey for a boomer (thats someone who is old). "I cut the skin off of it and saved it for future repair to my DD". "skin" is the outer shell of a monocoque chassis. "It" refers again to the 986 car type. I didn't use a coma to separate the compound sentence, but its not always necessary to do so. The "it" in the second half of the sentence refers to the forementioned skin. "DD" is colloquialism for daily driver.

I'll admit this next sentence is superfluous. "As it so happens the RF fender is on my DD now". I use this sentence to describe how I used the "RF" (that means Right Front) fender. I again use the two characters DD to suplement writing daily driver.

This final sentence is a bit clunky but we can brake it down into one compound sentence, then clarify. "I used the junky fender that was on the boxsterado on the RX986 (for the fuel door), and swapped the blue fender (resprayed) onto my DD." The word "I" is the subject for the first part of the compound. The predicate of that part is "used". "the junky blue fender that was on the boxsterado" could have been better separated with a coma as it describes one thing. "on the RX986" is a preposition. "On" in this last part of the first side of the compound sentence is the preposition describing where the "junky blue fender" was going. "(for the fuel door)" I used paratheses to try to separate this thought from the rest of the sentence for clarity (I failed). The subject for the last half of the compound sentence is an implied "I". In the second half of the compound sentence "swapped" is the verb that is being done to the fender. "onto" is another preposition describing where the blue fender is going. "DD" is used again at the end of the sentence.

My engine swap thread seems to have metamorphosed into TikTok posts in my absence. I'm still busy setting up my new house and shop, and I want you kids to be on your best behavior while I'm away.

I was enjoying your English 101 lesson until I hit, "...but we can brake it down into one compound sentence...".

That's where you lost me. Nice try. :cheers:

I'm still alive, still getting things set up at my new place. In the meantime, since putting the car on jack stands will be my first order of business, I've been thinking about how to make the process less frustrating. The main problem with jacking up Boxsters is the lack of jacking points at the centerline in the front and back. Without them, one must use the "approved" jacking points which, instead of at the center line, are offset a foot or so to one side. As a result, the car is not side-to-side level when elevated, which causes aggravation when trying to place jack stands under the car.

Consequently, I've come up with a Grant Hargraveish solution: a 5"-wide steel channel crossways on the floor jack, with rubber pads that correspond to left and right jacking points. The channel will be upside down on the floor jack in order to keep the profile as shallow as possible and also to prevent the floor jack's pad from slipping off the channel. I ran this plan by my friend the metal fabricator, and he gave it his blessing, although he thought steel would be preferable to aluminum, because he thought aluminum would flex too much. The issue is moot, however, since I couldn't locate aluminum channel wider than 4". Rubber jack pads, including the one on my floor jack, are close to 5" in diameter.

I would be interested to hear folks' take on this scheme.

That should work, but you don't need to do all that. The suspension and body are stiff enough that even if the lift points are off-center, the lean won't be all that much.
