Is it possible to increase the bore on the 2000 3.2L Boxster S motor?

[TypeS]

Hi,

I'm a very experienced motor rebuilder and long time auto mechanic - although 20 years removed from doing any pro wrenching. One year ago tomorrow, I took possession of a 2000 Boxster S, in immaculate condition. Other than my having to disassemble the CD300 changer to remove a stuck CD, I've had absolutely no trouble with the car and totally love it 1 year and 20,000+ miles later.

My question is simply this - Can the displacement of the stock motor be increased by larger diameter sleeves and/or through boring the cylinders? I've found nothing on this topic, and I'm not implying there's anything wrong with the way the car performs now, but as I have an insatiable curiosity regarding this, and have found virtually no information on the subject; thought I'd post my interest here.

If it's possible I might consider doing it over the course of a coming winter, as I'm sensing the chassis (optional turbo 18" wheels) could easily handle more torque and power, and although there's been no discernible diminishing of its performance, the only weakness I detected on taking possession was that the previous owner rode the clutch, and my monitoring tells me I'll need to replace it (and all other accesable replaceables once exposed) within the next 30,000 or so. So thinking how much I enjoy motor rebuilding (I've really missed that time in my life), just wondering what displacement options would be available since other than machine shop work, all other labor would be at no cost.

Thanks,

Jack (2000 Boxster S - 18" Turbo wheels)

The short answer is yes -- goto www.lenengineering.com

I was going to have my 3.2 bored out to 3.6 -- but I didn't need

to replace the cylinder liners -- so I did not do it.

I am however getting their new IMS system.

Thanks for the reply. When I tried the DNS it could not be found. Could you double check?

I think everything you need will be here. If you go to the trouble of making a bigger engine i would also do all the little things that will make your motor bulletproof.

Hello,

I am Jake Raby,

creator of the Flat 6 Innnovations M96 engine program.. I'll go over your post below in detail.

Great, you sound like a much more advanced "wrench" than most Boxster owners. Fortunately for you as well as the at home Enthusiasts we are now offering ready to assemble engine assembly packages along with training DVDs and formal workshops on the engines, and how to use our updated components to assemble stock or Performance M96 engines.. Each package comes with full block boring and Nikisil sleeving and we can take your 3.2 to a 3.4 or 3.5 engine with two different kit assemblies that include everything needed to complete the engine, it's all balanced and all engineered by yours truly to be compatible- just like our developmental engines. All kits have our billet IMS, oil system upgrades, Nikies cylinders and JE pistons and even fully prepped, ready to bolt on heads.

My question is simply this - Can the displacement of the stock motor be increased by larger diameter sleeves and/or through boring the cylinders? I've found nothing on this topic, and I'm not implying there's anything wrong with the way the car performs now, but as I have an insatiable curiosity regarding this, and have found virtually no information on the subject; thought I'd post my interest here.

What you desire was previously not available, but my company and LN Engineering have been working behind the scenes for 3 years to make this possible and the results are stunning. The 2.5 engines go to 2.75 liters.. the 2.7s go to 2.9 and the 3.2 can go 3.4, 3.5 or 3.6 liters. The 3.6s are now going to 3.8 and possibly 4 liters. The cylinder boring process is difficult and costly to make an arrangement that is really effective.

If it's possible I might consider doing it over the course of a coming winter, as I'm sensing the chassis (optional turbo 18" wheels) could easily handle more torque and power, and although there's been no discernible diminishing of its performance, the only weakness I detected on taking possession was that the previous owner rode the clutch, and my monitoring tells me I'll need to replace it (and all other accesable replaceables once exposed) within the next 30,000 or so

.

Preventive measures like a replacement of the IMS and a tear down/ update of the engine before it's necessary is a MUCH cheaper alternative to do the work after the engine fails.

So thinking how much I enjoy motor rebuilding (I've really missed that time in my life), just wondering what displacement options would be available since other than machine shop work, all other labor would be at no cost.

One reason the Boxster engine has been touched by so few people is because it's a ***** to assemble if you don't have step by step direction and if you don't have the proper tools. I have been assembling engines since age 8 and have hundreds of builds under my belt, the M96 is it's own beast and it isn't easy to build at all..

Our program is being developed to offer turn key performance engines, both N/A or boosted as turn key packages, but the big hit has been the engine kit program that will empower local shops to assemble these engines with our support, our tools, our parts and our training.. A similar training session done at our facility or on DVD is coming for the enthusiast in 2009.

If you have 20 years of experience, you could do the job yourself but you'll need the special tools and lots of patience to do the job. The M96 is nothing like you've experienced in thae past and you must realize that now- if not it WILL tame you quick!

Let me know if you have any questions... 350 HP is just around the corner :-)

Thanks for all the feedback. I can hardly wait for the clutch to start slipping!

Cool!!! You can accelerate the clutch failure if you'd like... We are ready when you are! Break that sucker!

Hey Jake, it's Jack (TypeS).

I'll be patient. The car is such a sweet ride as is. Today was damp and cold and I still had the top down and ran the heck out of it along the great foothill twisties I'm so blessed to live within; but you've definitely got my attention. What's the projected cost for the kit with video -as I certainly wish to rely on someone with first hand experience with this motor, as my rebuilding days predate water cooled Porsches and exclude anything more ambitious than one valve job on a dohc motor (a relative rarity back in the mid 80's when I hung up the wrenches)?
