So in recent weeks, alot of digging around for info and this and that and I came across the factory 2.5 TIII again, I already new about it but you always forget. Anyhoo, found another link mentioning it uses a basically stock 2.5 bottom end except for a one off forged crank. So this has me puzzled, the compression should be around 7:1 but yet they say it runs awesome???
