9 Benjamin's for a cage - OMG!@!! I paid $265 for mine in February. I was too cheap to pay the $100 shipping for the 3 hour ride and went and picked it up. I'll admit that I feel bad for the north of border bunch - that's BS.
I'm not sold on the fuel rails though. With those you'll need two completely separate fuel systems. I'd prefer to lose some trunk space and add a couple of shutoff valves to swap tanks.
p.s. - did you ever pull the suspect rod?
Im all fairness I went 0.080 wall Chro-moly, It was only a couple hundred more for the upgrade, is stronger and shaves off like 40-50lbs. Didn't need it but....
Getting it here was 1/3 of the cost, but compared to a local Quote of $4000 (Maybe) it was a steal.
With the fuel rails I have some options, my 4303 is external and can feed everything the current turbo can make, so it could be the second system. Unfortunately I have to make some other changes (Dominator ECU/ Separate Injector driver $$$
) before I can go that way. The Price for dual injector setup was almost NIL and I could swap injector plugs/ Load kill tune at the track for full send mode right now.
