I don't think is 4.4L for the GTR. The regulation to be outclass winners need to use a standard car with minor modification shocks, exhaust, roll cage, bucket seats etc. GTR N1 Spec was only like 300hp
Too bad they can't get the NISMO spec
It's not actually a 4.4L. They have a multiplier for turbos. So a 2L turbo isn't classed with 2L NA cars. I'm pretty sure it's x1.7 for turbos. So it's a... 2.6L turbo.
thats right, 4.4L for a GTR hahaha.
i think there's now hardly any mods allowed engine wise (exhaust and computer only sort of stuff), but suspension and brakes are allowed.
