Big Bore 3.2 to 3.8

3. I assume your prices are for outright purchase. What is the value of a good core?

thanks, and good luck with you venture

The 3.4 engines have a few serious issues, some of which we have not addressed as of yet, especially trying to repair cracked heads. Many of our other adaptations and developments can be universally applied to the 3.4, just like the 3.2

The 3.2 engine uses a sleeve like the other engines, the material surrounding this sleeve is weaker due to the larger bore. Our process creates a thicker bore for the 3.4 than that of the 3.2 and then employs Nikisil plating. This is what eliminates the issues.

The price to update a 3.4 is just slightly more than a 3.2, but thats according to the condition of the core that you send back to us.

The early engines (2.5 & 2.7) are the only outright engines that we offer now, as the 3.2 and 3.4 cores are harder to find. We are currently requiring cores on all engines so we can build a core bank that will support outright purchases. We have a good supply of cores now, but most of which are needed for test engines, for developmental purposes.

By this time next year we should be able to sell out right engines with a core charge of 2,500.00 or so.

Its going to take us years to prove that we have remedied the issues created by Porsche with these engines, and with their bad rap thats easy to understand... BUT once the major issues are over come the engine becomes a really heavy hitter with serious performance capability.

Jake-

I have the utmost respect for your work, and am very interested in the possibility of a 3.6 conversion from my 3.2, however, I am still a little confused by the claim of 350HP from the 3.2 heads and intake runners. I know the 3.6 heads are quite different, featuring VarioCam Plus and larger exhaust ports, and the X51 heads have different cams. The 3.6 has a larger intake manifold. How are you going to wring 350HP out of a 3.2 with bigger bores but the same heads and runners (with perhaps a valve job)?

Also, is the price $15k PLUS sending in my good core?

The engines using the 3.2 heads that are modified will be constructed for higher torque and less peak HP, more than likely. BUT the stock 3.2 head already flows enough when coupled to cam mods to produce well over 320 HP.

All the engines seem to have ports and valves that are very large for their stock displacement, when compared to other engines. We can typically make 1.2-1.4 HP per FFM of port flow with an optimized combination and the best part is the 3.2 heads will make the best torque of any head and torque is what the Boxster needs more than anything.

HP sells engines, torque wins races... With a car thats as heavy as the boxster torque is king.

As far as cost goes, you guys don't seem to grasp the fact that our turn key packages are just one of the offerings we have.. Our biggest goal is to get our parts, tools and training into the hands of your local Porsche shop so they can provide a similar engine comprised of engineered components into your car.

You may want to spec the more aggressive profile of the X51 cams too

Done. The next step is digitizing the heads for replication.

I'm sorry, I didn't see your reply. Even with my fanatic viewing habits, things can get buried too deep.
