Anyone have a Raby rebuild yet?

With respect to the 3.2 to big bore 3.6 program, how are you tackling the top end breathing? The 3.6 heads are quite different than 3.2 heads, as is the exhaust its bolted to. I'd be very interested to see a 3.2 bored to 3.6 with Nickies, all other updates, and topped with X51 3.6 heads

I am VERY interested in what you are doing, and I think its fantastic that someone of your caliber (I am very familiar with your air cooled work) is finally going to provide a solid solution to the M96 motor issues.

Thanks for the compliments.. We are attacking the Boxster challenges with the same level of enthusiasm that we have (and still do) with the Aircooled engines. This work is easier than the aircooled work because all we have to do is overcome the reliability issues and we have a great foundation to work from.

As for cylinder heads, thats an area that won't see as much work as one might expect. We have already determined that the stock engines generally have a lot of capability built into them and in some instances can flow more than the stock engine needs. We are working to boost torque and extend the usable RPM range, not just make HP at some really high RPM that might good on paper, but ends up driving like crap down low.

Due to that the current hypothesis is the 3.2 heads will flow enough to create a torque monster that is still able to rev to redline easily, this decreases the need to beat on the engine and abuse it to get the power you are looking for and that keeps things alive.

We are looking to source an X51 head to study and see what the logic was at the factory, not so much to replicate, but try tom improve upon.

Given the fact that a good solid valve job can add 15HP to a stock 2.5 engine we don't believe that a super huge set of ports and alves will be needed to attain the power we are looking for from the 3.2>>3.6 modification.

This has turned into an excellent thread! My 2.7 is approaching 80k miles and has been rock solid reliable, but I do know that there will come a day when it's time to address an engine replacement. I had thought of moving to a Carrera after the Boxster, but after driving several, I still find myself preferring the Boxster, but just wishing for more power. My plans have been to transplant a 3.6 when the 2.7 checks out, but after reading this thread I am pleased to find that there are more options than just a factory engine swap.

I am very interested in the 3.2 to big bore 3.6 program, but I have a few questions. My core would be a 2.7, so I assume there would be an additional charge since I wouldn't have a 3.2 to offer as my core. My Boxster is a tip, and I'm wondering if the tip would hold up to power of the "3.6"? I like my tip for driving in heavy traffic and am comfortable with my manhood to not let the manual only crowd effect my self esteem. I also have plans to put a limited slip in while I have it all apart for the engine swap. Would I have to change out my DME from a 3.2 or could my 2.7 unit work with a reflash?

My dream of a "Monster Boxster" is beginning to look like a very viable reality. :dance:

We have had several Clients with good running, low mileage engines that wanted more power and our reliability enhancements. A good number of these have sold their engines to opthers that have had engine failures and gottan 3-6K for them, then put that "free money" toward their new engine from my company.. I sell them a core engine (ildly broken and in need of update ) for 1500 bucks or so..

This is a win/ win for everyone as someone with a broken Boxster and a smaller budget can get a new engine with no issues and the money can be put toward the high performance FSI engine.

We have cars being shipped from all over the country to our expanded facility for our 3.2>>3.6 upgrades. Most are around 20K including installation and shipping from most anywhere in the country.. Shippers are starving and will haul cars dirt cheap!

Jake, what about just parts for rebuild. I have a friend that has a lot of engine rebuild experience with Subaru's and has rebuilt 4-5 aircooled Porsches. I thought originally, that was the plan, getting the parts out for DIY and local rebuild.

Complete engine kits are coming this summer along with training..

Right now we are still developing the combinations that will be used for this and testing them, since they are different than the turn key offerings..

All the testing and development takes a lot of time... I don't even have time to work on the website!

Any news on the M96 rebuild program?

[mikefocke]

other than Jake has a big backlog of orders, has built another building and you occasionally hear of an engine that was either IMS-updated or completely rebuilt. From a news perspective, a lack of bad stories. Guess the owners are busy driving. And he doesn't post as often because he is too busy...and the subject has been talked to death.

Can each customer can customize their options like cam, compression ratio, ECU tune.... ect ect or is that pre-determined?

To a point.. I do build Custom engines, but the user generally doesn't understand enough about the engine to dictate any components or set up. There are windows for customization. Basically tell me what you want and I create it from scratch as a complete package.

So a stage 2 is roughly 19k. What is the difference between stage 1 and stage 2 exactly?

1500 bucks of the difference is the CNC port work on the heads that has been proven to add 30CFM of port flow. The CR is also different and while the stage II uses stock cams, they cam timing is altered to my own settings.

I assume if the customer wants you to use their original engine and not do a core exchange and get someone elses that would be ok?

I prefer to build the Customer's engine. I stay away from core exchanges as I prefer to build from an engine that has a previous history that we can document.

Haven't had time to catch up with this thread. How many engines are on the road now and how far are you with the engine kits for DIY like you do for the Type 4 engines?

I just got done rebuilding the engine in my 08 STI (don't even ask, it's a long story) and the Boxster is coming up on 70k. I am going to give it to my son in 2 years when he turns 16, but I don't want it to blow up on him. How much am I looking at for a reliable 2000 stock 2.7l fully rebuilt or as a kit? I'd like to rebuild it with him, it would be a great project together.
