ebpv and butterfly valve delete...
So I got bored and decided it was time to change the turbo o rings because of the slow leak... While I was at it I did the ebpv mod, and took out the butterfly valve. when I took the turbo out I noticed a bad up pipe leak...
long story short, snapped 3 of the 4 bolts off on the adapter manifold, had to order a new one 118 bucks. turned into a 3 day job. wow lining up that adapter flange is a BIAAATCH!!! WOW. anyway, then tightening up the bolts on the up pipe flanges with the turbo in is a bear...
But- after it was all buttoned up it boosts up way quicker, egts are down significantly, and it runs much better. the only thing that gets me is how much different it sounds. It sounds WAY different without that valve taking up all that space in the exhaust port of the turbo. I would recommend this mod to anyone.
Built engine, rods, pushrods, cam, springs. Meth, turbo, injectors, fuel system, oil system. 3 disk billet, billet shafts built trans, 6.0 IC, exhaust, intake. Latter bars, gears, system, tint, HIDs. You know the typical stuff to make a 7.3 get out of its own way...
