can a Porshce 911 Turbo engine be put in a Boxster S?

Question

- I know you can't put V8, V10, V12 in a Boxster S, but I want superior track performance. And if so, how much will it cost?

- I don't want to lose to a BMW or Lexus on the track. If there is any way to really hype up my speed without spending $40,000+, that would be great. I already am expecting to spend between $60,000-$86,000 on the Boxster S.

Answer 1

It would me more expensive than it's worth. It would be in your
best interest (if you want the 3.6L turbo engine) just to get the
911 Turbo itself (i.e. the car).

You would be looking at about $50,000 to have the turbo engine
installed into a Boxster S -just to give you an idea as to the cost.

If you already have the Boxster S, you could have them upgrade
yours to the 2007 engine, and then you can upgrade the exhaust
system, intake system, add a turbo or a supercharger -and voila!

Answer 2

If you want superior track performance you are probably chasing the wrong solution. If you are to look at the cost (and $50k is probably in the right area for this kind of change), you might expect to see a sudden increase of 2 or 3 seconds a lap. However, this would be a diminishing return as the higher speeds would have a negitive impact on your braking and you'd lose one or two of those seconds back before too long.

So, how to actually get superior track performance? You could invest in a few track days with instruction. This is the biggest bang for the buck as you'll likely find 10+ seconds right here if you're a novice (and if you're not, why are you worried about someone lapping faster? There will always be someone faster). A second set of rims with R Compound tires would give you at least 2 or 3 seconds... depending on what rubber you have now and what you go to, you might see more than that. Suspension upgrades can find you another 3 or 4 seconds as well. All of these will get you more actual performance than the engine swap.

On a personal note, I've driven more than a few Boxster S's at the track and have never really found them wanting for power. Yes, a Twin Turbo will have gobs more power, but so what? The driver will still be the biggest part of the equation in either of these cars (as well as the Lexus or any other car).

Answer 3

well for 65 or so thousand, you can buy a 996 turbo in great condition. My neighbor recently bought an 02 with about 33 on the clock for 64k. Great condition.

if you want more track performance, i would first worry about the driver, not the car. 90% of performance on a track is the driver. I do Porsche CLub of America trackdays, and i pass 911s and boxsters and such on a regular basis in my VW GTi vr6, despite it being a much slower car on paper.

and if you want a track monster, get a lotus exige S. 240 hp, 1900 lbs, stupidly fast.

or if youre going boxster, mod the suspention and such first, HP wont help as much.

Answer 4

Hey listen, If you are willing to put that type of money to
exhange engines, why don't you wait until the new boxster S
comes out. It will have the new 3.6 litre 911 engine already
installed. All you would have to do is add a supercharger or
turbo and you would be set. You can probably trade your old
boxster and half of the money you mentioned to purchase the
car.

Answer 5

You will save thousands of dollars and years of heartache by simply having your Boxter engine race prepped by a professional engine builder/tuner. This way it remains a 'bolt-in' application and will suck the doors off most anything providing you know how to drive it without killing yourself.

Answer 6

You should have gotten the 911 in the first place.

Answer 7

they are all interechangable with the fittings and the hose placements in most cases, some cutting may have to be done to fit it in, but i doubt it, why would you wanna do that anyway? 911 engine would be too heavy for the boxter i would think

Answer 8

yes
