awesome work... i know the complexites also... just did the rear mount turbo on my ranger 4.0l... no boost lag... too quick actually... i have been wanting to put twins on my 2000 lsv8 , the packaging is much simpilier than the roots or screw , not to mention efficiency and power gains. smart use of the meserie pump, i got mine from sts... since we are a dealer rick sold me just the pump after some pleading... never thought about water pumps... did you get a vacuum on the suction side and how did you restrict the pressure side... i used holley jets since they are common... did you have oil accumulate after shut off, i did.. i think i needed a pressure check to stop oil flow after the engine was shut off and this would have solved it... that was my only issue.... it is fun to blow away rice cars with my ranger on 39.5's, you should see the looks from these kids as they are powershifting third and i'm still right next to them laughing... it is awesome to hear from another turbo junkie out there... keep it out back too, why clutter up a perfectly good engine compartment... by the way, when did you get full boost by (rpm), mine is off right now because it spooled too fast, 8 psi by 2500 rpm in fourth, turbo was too small, excessive ebp, was thinking t04e p-trim might be too much.....lol
