Anyone have a Raby rebuild yet?

[Jake Raby]

There are several methods of ECU manipulation and the method we choose will be based upon what we have done to the engine and what engine we are working with.

Lots of the items we are working on are well within the realm of "learning" by the very smart Motronic ECU, this is mostly true with the early engines.

We'll prefer to receive an ECU from the client's car and then use it for engine tuning with the replacement unit. Its a plus to keep the stock ECU with the car whenever possible.

Today I began measures to re-outfit our facility with an area and crew to complete full service engine installs/ swaps into the Boxster and 996. We have typically been an engine design/ assembly and research/ testing facility only, but its apparent that it'll be a necessity to offer full services to those who want innovative flat six power :-)
(some are willing to ship engines cross country for us to do the installation)

I'm considering a 3.4 conversion in the next 6 to 8 months. What are options with 2.5 block. I want something that will be capable of 300 reliable HP. I'd also like something that will give me better low end torque range. I dont know if a 2.5 bored out to 2.9 would be solution?

I would think that the 2.9l would end up somewhere between 270-280hp. I think once you start getting close to 100hp/liter or more, you are pushing things in any engine. You don't have VTEC yo.
