3.4L vs. 3.6L Engine Swap

[Perfectlap]

$40K is a bargain man. Look at all the power you are getting.

Porsche is charging 997S owners $20K for the X51 upgrade which is just their version of the "exhaust, intake, chip" upgrade that hardly results in any big power.
Hmmm....buy a 2nd hand S2000 or a nice sound exhaust for my 911?

Bargain is a relative term. For $45K, I can go buy a new C6 Corvette that already HAS 400 HP. That is for an entire car.

To each his own!

Hello, all,
I am new to the forum,
but within the next day or 2,
I should have finalized the purchase of my first Porsche,
(Having driven VWs exclusively for all my life)

1997 Boxster w/ 3.4 from a 2000 911.
Engine mileage: 40k (installed at 19k, so it is certainly sorted out)
I am not intimately familiar with all of the details of the swap,
but I know there was a different intake manifold involved,
and a custom ECU (from the Vaterland) involving reprogramming
the boxster ECU to work with the new engine.
Apparently the ECU is so intimate with the chassis of the car that it made sense
to reprogram this one instead of swapping to the 911 ECU.

I know there is more to it,
but those are the hilights as I recall them.

But, I certainly will have a fully functional example in the next few days,
so should be able to answer visually identifiable questions.
(If I decide I want to help someone else experience the glory, instead of keeping it all to myself!)
But, categorically brilliant swap.
Arguably the best car I have ever driven, not that that is saying a lot.
I could not speak more highly of this engine / chassis combo.
(Keep in mind the car is well sorted as well: S brakes, Eibach coilovers, corner balanced, good weekend track car)

Sorry, found it on a google search from
"Boxster 3.4 engine swap"
and did not check the dates.

My info is probably old hat to you guys by now!

It's all good. Rather see an old thread resurrected than a new one started. Glad you found us and joined the forum. Stick around.

Brad, Porsche thought the 3.4 was such a good fit that the new S's are all 3.4's albeit with even more HP and torque than your car.

I dream of taking my 97 and shoehorning a 3.6 or even a 3.8 in there.

Well, they don't have too much more power than I,
The new 3.4s are up to 310-320 hp, right?
(we had been thinking we had 300 stock hp, + chip and exhaust = 330-ish?)

All I know is it is plenty of engine for quite a while.
I have a lot of learning to do..

I have had one of almost every FWD VW,
but this really inspired both shock and awe,
when I put a whole tank of gas through it last week...

The cool thing is the car came with a driving instructor:
I found out after 2 days that with the suspension done,
and 18X8 / 10s, the only reason you should ever see the
TCS light is if you are not being smooth...
Once I started letting the light direct my cornering technique,
things got really cool. (and way fast)

but I digress...
I'm sure you guys will be hearing more from me once I actually buy this thing....

Brad,

Good luck with your purchase. Post back with some pics and the "story" when you get it.
