I'm gonna kick my build into overdrive so hopefully by august build will be complete and tuned.... Not the way I wanted but cause I wanted the car out next summer with wheels, full suspension, interior all done up and fresh paint but I have been given extra motivation to get it out quick with results.... So I guess I will settle for my engine being complete.

I was goign to get one, but the wait time on it was retarded. I ordered it in like August and was suppose to be there in Dec.. I ask at the end of Nov about it and they say 3-8 more months.. So I got a Comp turbo triple ball bearing billet turbo. I love it

speedjunkie has an EFR7670. the large hotside. His turbo rips up here in CO. kicks on super early in the powerband (2,000's rpms). He pulls hard all the way through the rpm range. I would guess low 400's WHP here in CO.

I have a 7670 had got it in FEB. Right after i get my megasquirt tuned to get full power but boost comes on super quick. Just trying to get everything put together. Also running the stock top mount so i have a HUGE flow restriction. Also wondering if any body has played around with wastegate sizing? Can i run a 44mm and not have boost creep? Right now i am running a 46mm OBX but the diaphram sucks so it constantly leaks by even at idle. SOOO i am in the market for a new wastegate but trying to go with the best size. PLEASE HELP!!!!

Also have a efr7064 with the 1.02 A/R T4 housing, would be perfect for a 12A, but I will use it in a sequential setup on a 2.0l diesel, so I am looking for an internally gate manifold for the 64mm tubine, preferable the T3, but could also live with the .92 T4 twin scroll.. if someone has one, let me know
