2004 Porsche 911 Nickies Lineup, Thanks to Brad for all his help! Options

[cnavarro]

With everyone's input from the forums, here's what the lineup for 2004 is lookling like:

For the 2.0: Still sourcing one. Once I have it in my hands, i'll be able to determine what overbores from the stock 80mm are possible.

For the 2.2/2.4: factory 84mm, 85mm, 86mm (new size, never before offered by anyone)

For the 2.7/2.8: factory 90mm, 92mm RSR, 93mm (bore size used by porsche for racing, a little thin at the skirt for my tastes, but they did it, so why can't we?)

For the 3.0/3.2: factory 95mm, 98mm (or any bore size between 95 and 98). I'm waiting on some factory cylinders for inspection to determine if anything over 98mm is acceptable. All cylinders will be in the later style, fully finned.

For the 3.6/3.8: factory 100mm, 102mm (available with the RS spec 107mm case register or RSR 109mm case register), 104mm (available on both 107 or 109 registers), and possibly larger with an additional resizing of the case and head spigots, as we're waiting on a 3.8RSR cylinder and furthermore inspection of the heads and case to see what the registers can be safely opened up to.

All Kits will come with later model air deflector tin updates and will be available with factory porsche motorsports or ARP head studs, your choice. Tentative pricing is going to be a flat $2999/cylinders only across the board from a 2.0 to a 3.8RSR set.

If anyone has any questions or would like to see anything else added to the lineup, just drop me a line at charles@LNengineering.com. Thanks for your input guys!

Again, thanks to Brad for helping me put all this together!

Let me try to reprase my question. The 84mm cylinders have their own program, so do the 90mm cylinder. I know the registers are different, and that an early case would indeed be opened up to accept the later. My question is rather I am pretty sure that there are some dimensional differences between the cylinders, i.e. length, where the step on the skirt sits on the case, etc. Would the 89mm be a new program with the heights of an 84 cylinder and registers of a 90mm cylinder (or) could I just modify the program for the 90mm to make the bore 89mm? Did I make myself a little more clear on this?
