Since Tom has posted this link, seems like a good spot to introduce myself. I own Flyin' Miata and FMWestfield and we sell the Miata based Westfields in this country. I just signed on to the forum and will try to stay on track not proselytizing too much for the Miata powered Westfields, but I really do like the cars. I just turboed our car (stock 1800cc Miata with 120k miles), running intercooler, water/methanol injection and about 16 psi. Last year when I was normally aspirated I had to depend on the mercy of high hp cars to let me pass so I could play in the infield. Not any more....
