Like was said before...the 90mm is no longer made and is being replaced by the 92mm.

If you have a stock size motor and can get a good deal on a 90mm then I would do it, I dont think you will get too much gain for the extra 2mm on a stock sixe motor.

Get the 92 & port the snout to 95 & add this TB:


Ron at Vengence can sell you the intake already ported to match.
