986 Plenum swap - which one?

[BestGear]

Hi

That plenum is from a 3.8S by the looks of it - I could not find any reference to it online in terms of 986.

Could you post some pictures of it, showing the AOS entry etc?

When are you fitting it?!?!

Hi BG.

you might be right.
however, many guys on this forum did the exact setup with satisfying resoles.
if you have the time, read this extremely useful thread about the subject.

its a little bit long but will give you all the info you need.

in order to fit the plenum, you will need to use silicon reducers between plenum and intake, and new plumbing between TB and air filter.
i will take some pics of what i have and post it later tonight.

as for your last question.
probably never
i just finished a major project on my car couple of months ago (clutch,IMS,RMS,AOS...) and put everything back to stock.
the plan was to dyno the car (to get a base reading) and install the large TB, headers, test pipes, custom made exhaust, UDP and ECU remap.
the idea was to dyno the car in each step, and post the results.
not gonna happen.
the car is probably going to another home tonight.

Meir, say it ain't so! What is next? black is white? JD is a eunuch serving in a monastery? I've counted on your level-headed exploration of boxster issues since getting mine, relying on your sage advice to keep me from mod folly and point me in the right direction. Who will take up the mantle of mechanically enlightened layman, freely distributing the fruits of your knowledge to those of us more timid with our endeavors? The 986 brotherhood will be markedly diminished by your exit from the fold. And your poor car - think of the depredations it will suffer at the hands of the next owner!

have no fear, ill still be here

as some of you know, i have a neighbor that owns a 99 base, and i was helping him in the last year (in fact saved him more than 2K in labor and parts).
his car is in my garage at the moment.
he asked me to service the car for him.
after replacing filters, oil, and TB+MAF cleaning, i toke it for a ride.
10 minutes in to it, i noticed the car is overheating. drove it back to my garage, and inspected the fans.
driver side fan doesn't work at all. passenger side, only on high speed. (jumper the relays inside the car).
removed the front bumper and liners. removed 20 lb of leaf, and powered the fans directly.
Fans work. so resistors are toasted. Called him over to get his approval of ordering the parts (also found a creaked vacuum line at the TB), and had a little chat and he said how he wish he had my car.
As I joke, I said he can have it if he will give me 10K and his car.
Since the parts are delayed (waiting for the stupid vacuum line to come from Germany), I gave him my car so he can get to work.
He called me last night, and said that if I’m serious, we have a deal.
Im about to by my first home and the 10K will be nice addition to the down payment.
Sure, I put more than that in the car, but I get to keep his, and none would have paid me for what I put in it.
So not only that I’m not going any ware, I’m starting all over again.
Not sure what I will do with the “new” car yet (a silver 99 base with 150 k miles on it)
But that will be another thread.

A monastery perhaps. But, "nun" such chance of me being there as a eunuch !
