Good advice Greg, but the email letter's already sent and I wouldn't want to confuse it with supplemental info (unless asked). Note that the ITA Miata 1.8 weighs 2380, ITA Miata 1.6 weighs 2205. So yes, the ITA Scirocco 16V at 2320 is already slightly lighter than the Miata 1.8, but 115 lbs HEAVIER than the Miata 1.6. If there's one thing I can compare with after this year, it's that my ITC Scirocco 1.7 at 2110 is significantly slower (say 3 seconds per lap) than a well-driven SSM Miata 1.6 that weighs 2300 in SSM trim and runs 1:03s at Lime Rock.

Now, subtract a second for the SSM to ITA mods, and another 1/2 second for the 95 lb SSM to ITA weight reduction, and the Miata will be running 1:01-1:02 at Lime Rock (born out by Andy's recent track record, although I think he did it with a Miata 1.8). The ITC Scirocco 1.7 at about 2110 can run 1:05-1:06 at Lime Rock. The ITB Scirocco 1.8 8V at about the same weight can run 1:04-1:05. The ITA Scirocco 1.8 16V, if it were reduced to weigh 2100-2150 lbs, might be able to chase the Miatas. At 2320, there's simply no chance. At the current weight, I think it would be an incredible feat just to break into the high 1:03s, with 1:04s more likely. If it gets a meaningful reduction, I'll probably build one. If not, it's simply not worth the effort.
