Will the turbo get the heat shield treatment as well or is that a bad thing to do?

We've already ceramic coated everything. So heat is kept to a minimum already. On this particular build the client also chose to do a turbo "blanket" heat shield and additional wrapping on some of the other exhaust components.
Any pictures of where you put the oil drain in the pan? Weld on fitting?
Looking good! Can't wait until you have a kit ready!

We have had the kit ready for orders for a couple months now. PM/email me if you're interested and have any questions.

If there is a harder way - I will find it...
Did you ever get HP and Torq numbers on it?

Will be put on the Dynojet once it's back together and gone through all of our breakin and testing procedures.

Bung welded to downpipe, fitting attached, for crankcase vent venturi pipe.
This is basically venting oil and contaminants directly to the atmosphere via the exhaust.
Is this legal?
No, but the pcv system basically does the same thing 
I prefer a separate catch can system with a recirc back into the intake. You can also just run it to a catch can with a vent and drain it periodically. I've also done a catchcan setup where it drains back into the block. The oily bypass has to end up somewhere!

Most of these high mileage cruisers burn a quart of oil in between oil changes or more. This build will leak/burn nearly none. If you're burning that much oil, you've got bigger problems to worry about than whether it's legal or not.
On this setup. We removed the PCV, and welded an aluminum nipple to the valve cover. We then routed the two nipples off of the valve cover to a catchcan. The catchcan has a drain that goes to the oil pan. The catchcan also has a vacuum nipple that is routed to the fitting on the downpipe for as much vacuum as possible. So there's no oil being pumped to atmosphere at all. The venturi on the downpipe is just used as a vacuum source.
The MannHummel Provent 200 removes nearly all of oil and contaminants before returning the oil to the pan. The exhaust vent keeps constant vacuum on the crankcase that increases with RPMs vs the OEM PCV system that decreases vacuum as RPMs increase. The OEM PCV system allows positive crankcase pressure at high rpm.
The desired effect by filtering and using exhaust vacuum is blow by gasses get filtered before reaching the exhaust (far less reaches the exhaust since increasing vacuum pulls oil away from the combustion chamber and there is no PCV through the intake). The very minimal amount of filtered, clean oil that might make it past the oil separator is vaporized instead of burned. Most oil is recovered from the blow by gas and cleaned before it is returned to the pan.
Without vacuum, oil travels in large quantities past the rings and is burned in combustion (much more at higher RPMs) before going out the exhaust while more blow by also enters the crankcase past the rings in the other direction (also more produced at higher RPMs though it stays in crankcase until lower RPMs allow PCV to vacuum it out). At lower RPMs, when PCV works, blow by fuel/oil is put through the intake and into combustion, burned, and passed out the tail pipe. PCV reroutes the partially burned hydrocarbons found in blow by gas to be burned again in an effort to reduce the emission of partially burned fuel/oil.
Filtering blow by and maintaining constant vacuum on the crankcase is cleaner, but obviously not OEM. An added benefit particularly for FI is that octane isn't reduced by the large quantities of oil ingested (especially at higher RPMs).

so this is a legal setup then, or isn't it?
Anything other than the OEM routing will fail a visual check at a check station regardless of whether it does better. However, properly disguised most technicians wouldn't notice a thing.
Most counties in Texas don't do emissions testing, but once the vehicle is over 25 years old it no longer gets checked in those counties that do.

Legal depends on where you live and what county the vehicle is registered in. In some counties, removing the stock air box, doing a lift, using aftermarket armor and bumpers, etc is illegal. Whereas in some counties you can register a fully modified 1000hp dragster as legal.
thanks
