Looking to get some more power
I've been toying with getting some real power out of my boxster (300+)
I've considered the intake/header/exhaust question. For the amount of money involved i'm wondering whether i should go for a powerkt or a new engine. What do you guys think of these options? 9ff Powerkit or go for the big guns and run down turbos 4.0L engine i thought about a supercharger but my research tells me that boxster's engine compartment is hot enough already! I'm leaning towards the engine, 8500rpm of pure NA power literally sounds amazing. |
The power kit seems to be a near waste of $7500. 20HP is not nearly enough to bring that sort of price tag. I would think you could find a 3.4 or 3.6 engine for around $10K. Just my opinion but I believe at some point the horse power would throw the overall balance and handling of the car off. To me these are the reasons one would buy a boxster. If your looking for that kind of power maybe check into used 911's. If you do have an engine swap document the entire process and share the experience. Good luck w/ which ever route you decide on.

That kit for $7500 is way overpriced. You could just buy the EVO intake and "chip" it,and receive a extra kick for alot less. By the way what year and engine do you have?

Well, support from the standpoint that we REALLY want you to do this. Pictures of the installation would be excellent. Also photos of any resulting explosions would be nice. But seriously, don't listen to anyone here who says not to do this. We WANT you to do this. You NEED to do this. I NEED you to do this. Please, for the love of GOD, do this! Good luck. We're all behind you..... waaaay behind you...... |
A 4.0L M96 engine? I'd love to know what they want for that. I'm guessing around 20K?

On a track or autocross track your average MPH would be higher particularly down the straights so there is a greater chance of over-running the stock brakes. Also, when you get on the gas weight transfer happens. The nose lifts and the rear squats coming out of corners. More power means more weight being transfered on the back tires. That is why it is common to see upgraded brakes and stiffer suspension setups when the power goes up to counteract these things. |
I'm with mtch. Why is it inevitable that you will "overrun" your brakes when the S has the same brakes as the 911 which has more HP and is heavier? Further, a stiffer suspension increases weight transfer front-to-back. Most of what is presented here as fact is merely opinion or a rehash of someone else's opinion.
While a lot of people are just fine with their 2.5L engines or 3.2L engines, some people are not, and I get tired of people telling them essentially to shut up and enjoy what Porsche limited you to. Personally, I cannot think of a better (in my definition) car than a Cayman with a 3.8L dropped in. For many others, that is not the best. That is opinion. |
I called this company and talked to a guy about a 3.4 engine. It's customized heavily, with polished and ported heads, etc. It comes with all the intake and exhaust required for the swap, as well as a new ECU. You do have to give them your 2.5 (I asked about my 97 box) to get their website pricing of 16,500.00.
Then you have to give an authorized installer about $700 to swap it out for you. Upsides to the 3.4 package they sell: Different RMS from what is on the car now, and a clean install with a custom engine built for racing with a 8000+ redline. Holy smokes that's high. It also cranks out 305 HP or a tad more. You know, I realize this is more than I spent on the purchase price of my 97 two years ago, but I think I'm going to save up for it and do it in a couple of years. I've finally gotten all the interior and maintenance bugs worked out of the car... now it's time to start saving for an engine upgrade... the supercharger route will create too much heat and shorten engine life. |

Sounds like a really cool upgrade! I checked-out the website and was very impressed.
But, once you have the money saved and before you greenlight the swap-out just drive an S model (probably best to drive is a 987, 280HP S). This way you've done all the research. best of luck bob |
I will do that. I'm just in so deep financially with my 97 now that it's hard to consider taking a bath on it financially and starting over with another car.

For those who wants to drop a 3.4 in their boxster, they should test drive 99-01 996 cab to see if you are happy with the gain. I drove my buddy's 99 996 cab and didn't find much difference in power - on the street and the track.
The intake, exhaust, cat bypass, chip upgrade will get another 25hp and cost about $3K. Or Clubhead got the header, sports cat and exhaust for similar gain. |
I too think about getting the 3.4L upgrade in a few years but I waffle on whether it makes financial sense (Well, if driving a Porsche makes any financial sense.) Let's say I can sell my Boxster sells for $10,000 in a couple of years (maybe for alot more if the spec Boxster racing ever gets off the ground.) With the money saved for the engine upgrade, that's $27000. A quick look at Autotrader and I can get a 5 or 6 year old Boxster S with less than 40K miles on it. Decisions, decisions, decisions.

I did drive a 01 996C4. I found it to be significantly brawnier than my S - maybe it was the exhaust it had, but either way, i would imagine the c4 is at least 400lbs heavier than a boxster? Either way, i'll be keeping you guys posted. I've also been thinking about a carrera i must admit, but by the time i get a conv optioned how i want....its a ton of $$$$$. I wonder whether id be happier with a "me too carrera" or a tricked outr csutom box that will blow away the portly, awd carrera. |
A lot of money to upgrade a car...seems like some of you bought the wrong car.
