I'm currently boosting my streetported 12a. I bought a used s4 turbo and mani. There is so much extra junk on there....what is all of it? Also, it came with this BOV what kind is it? Is it a good one?
:hops in flame suit: I don't know how you guys take to FB around here :biggrin: |
From the pictues it sorta looks like one of the turboXS BOV (that and it says it on top). I'm not sure which one, but you can check it out at corksport (http://www.corksport.com) to get info on different models.

Thanks for the help.
Whan I said I was currently boosting the 12a SP, I'm really just int he R&D stage, I'm researching and gathering materials. All i know is how a turbo works and what i need to turbo a Carb. What i don't know are good combinations of Turbo/BOV/wastegate. What do you recomend for a 12a with an S4 turbo? What are some good wastegates and BOVs. I don't know if i'm going to re-route the exhaust gas from the BOV back into the intake quite yet, I might just use the one I got for free (pictures above). So I don't think a bypass will be absolutley critical to this project. Well, anyway...thanks for all the help! Mike |
The "extra junk" on the S4 manifold is likely the twin scroll and associated actuator. Look like a big silver can at the front of the manifold? If so, then just pull it off. Snap off the little flapper door in the manifold by hitting the exterior lever with a hammer. Now tap the hole, and install a bolt. You probably don't want to mess with having to design a twin scroll control system.
As for wastegates, the stock turbos have internal wastegates. While you CAN modify them for external, if you are going that far, you should probably look at a different turbo and custom build a manifold. As for venting your BOV, it's just easier to vent it to the atmosphere. |
Blow-through or draw-through?

Blow through. Thanks Cake.
On a good side note, I pulled the donor engine to get rebuilt and SPed today! |

I think a re-routed bypass valve would stabilize the system better, but I guess you could try the BOV and see how it works. After all, the BOV was free. |

yea, I'd like less lag, but I'll wait until I have more experince before I start worrying about rerouting the excess gas from the BOV.
What are some good aftermarket manifolds and turbo combos? Also, how much do 13b oil pumps run? I need one ASAP! (one that's out of a FB 13b) |
