Hey guys. Just letting you know that I haven't given up on my project. Work and busy season has pulled me off of it for a while. I have backed up and made some changes that should make a big difference. I had it all together and it was "seat of the pants excitement" compared to the stock set up. As a few people predected (and I knew in the back of my mind) it spooled pretty slow, however by the time it got to a certain rpm range it took off like I've never felt. I've since gone to smaller aftermarket turbos and downsized the piping. I'm expecting it to spool and come to life alot faster now.I'm still going to install a higher stall converter but that will be a little later. I should be buttoning up some loose ends and getting the last of the pipe work done and with a day off for Easter, I might even get to drive the thing. I just wanted to keep you guys up to speed who have been following this build.

What

Smaller turbos ? The goal is too go big .. Ive still got that brand new 2600 stall

Yep. but only slightly smaller. The over all out put will still be much greater than stock.

No new pics yet but I'll get some. Not much new to take pics of. New shiny turbos and re-worked the drain system that I had. I have the turbos draining into a small aluminum tank and I am scavenging the oil from that and shooting it back to the engine with the turbowerks electric scavenge pump mounted under the rear bumper fillers near the filler tube for the gas tank. It is out of the way here. I moved my bov from under the hood to closer to the turbos. It didn't seem to work well when it was that far away from the turbos. When I would let off of the gas quickly I could hear the turbos pulsate but the bov would never open even at the weakest spring setting. I have an appointment at the muffler shop on Wednsday to tie all the plumbing back in. After that I will rewrap all the exhaust and she should be ready for some tuning.

Why

You sending the oil back to the engine ? If youve got a tank and a pump make it a stand alone system for the turbos with a trans cooler .might see lower oil temps in the engine & turbos ..

I had a stand alone system with out the tank but a few seconds into wot the pump couldn't keep up with the oil that was flowing through the turbos and they would start seeping oil into the exhaust housing through those carbon seals. With this tank if the pump is over supplied with oil it just builds up a little in the tank (which should also cool the oil somewhat) until the rpms come back down some and the oil flow slows down. The oil always exits the turbos freely and doesn't back up. Oil is always flowing back to the engine so it is never starved for oil.

Makes

Sense . Man when your done i wanna come and see .
