A week after getting the car back together and clutch is all broken in, car feels wicked fast and I am gave a high-school buddy a ride to the airport, put about 15 bus-lengths on a ratty old honda and the car has me smiling ear to ear, so happy it is running good!
Next morning (Monday) I am getting on the freeway and I hear the sound no FI guy wants to hear...gerbils in a blender, banshee on her period, etc. Bleh! I am just amazed at my bad luck sometimes...I know the BBX has given up the ghost but there's nothing I can do about it now. I talk to Chris Carey at MAP....they have a ported, ceramic coated EF4X sitting on the shelf ready to rock. SO tempting....I talk it over with Anna and she says the most beautiful words, 'I know you kinda wanted one anyways, just get it!' So despite the trans issues just two weeks ago and an anti-tax return I pull the trigger. I need the car for work and no stock turbo in sight....done and done.
I limp the car home after work and Anna picks up the EF4 for me from MAP. What a gal! Pull the intake apart and sure enough there is damage to the BBX:
Talked to Chad Block @ CBRD and he is going to do a post-mortum on it and we'll see, maybe if I hate the EF4 it will go back on? :P I *really* loved this turbo!
So. Onto turbo pr0n? EF4 is a sexeh beast I must say. Compressor wheel is baby-munching good and even with the 3" inlet it looks surprisingly stock! Not sure the exact size of the compressor but it looks about 35r sized.
The fact that it is already ported is just a massive massive bonus for me. I have had all my turbos ported, and I must say this thing has a nice job on it. If my BBK Full on my evo8 was a 9.5 or 10 out of 10, I will rate this one at 8.5-9 out of 10...insane for an off-the-shelf port job! The port job on my BBX was nothing special but it obviously did the trick.

Down the scrolls, wow:
Check out that turbine wheel! This thing is a work of art...9-blade (versus standard 11-blade on a lot of other turbos, including my BBX), extended tip...this thing is gonna flow some serious air!
Also, it came with this nice, beefy oil feed line and filter kit:
Anyways, 2 hours later BBX was off, and 2 hours after that EF4 was about 80% of the way in...called it a night and then finished up the install tonight. Car still feels great but the boost curve needs some tweaking. Turned the MBC on my hybrid setup down a half turn for safety and I'm seeing 25psi at 4200rpm and then 30psi from 6000-8100+....it definitely rips but I'll take it easy and tune this week/weekend.
Very first VDR pull showed 581whp dynojet...BBX was at 550-560 at its best....I'm practically ready for proving grounds! Let's move it up to march 1?
