Decided to give up the CSL induction airbox life in exchange for a little but more power. (hoping for 350-400 whp with quicker spool and only running wastegate spring of 8psi)
My main goal is to have a turbo system on my s54 that give me just a little more power, quick spool and as much reliability as possible with an aftermarket turbo kit. I will be retaining the stock M3 exhaust system on my car which is the Section 1, 2 and 3. (i can swap out 2 and 3 later at any time in the future for larger diameter options if i feel the urge to.) I will be adapting the 3 inch down pipe to a Y pipe 3 inch to dual 2.25 inch with 4 inch on center spacing to merge into the stock section 1.
My oil feed/drain system will be as simple as I can get it to be consisting of -4an feed line from oil filter housing and a -10 drain into the oil pan.
I planned on draining the oil and tapping the pan with the new -10 fitting and then removing the center large cover on the bottom of the pan to access the pan internals to remove any excess shavings that may have got into the pan and flush it as well with fresh oil.
For the vacuum system i am tapping the end of the air rail on the end facing front of the car and installing a 4an-1/8 90 degree swivel fitting and running -4 black SS line to under the intake manifold to a vacuum manifold to Tee off the BOV, MAP and boost gauge.
We will be welding on the Tial 44mm WG flange directly to the Turbine housing for the 44mm WG and plumb that back into the Waste gate since i prefer a quieter option.
WG will get boost reading directly from compressor housing with a new 4an 90 degree fitting i tap it for.
e46 sedan with S54 swap and the parts i have listed below are what I have pieced together so far.
SPA S54 T4 turbo manifold
Borg Warner 200 sx &4 turbo 51mm inducer with .83ar on exhaust side
Deepmotor aluminum intake manifold
Tial 44mm wg
Tial 50mm BOV
28x9x2.5 tube and fin intercooler
an assortment of silicon couplers and tbolt clamps, reducers, 90s,45s
assortment of aluminum 3 inch piping to cut and weld for charge piping
friend of mine will be helping me with charge and down pipe cutting/welding
local tuner is working with me in hopes of tweaking the CSL TUNE file for turbo. We have gotten wonderful help from Terraphantm on some inner workings of the CSL file but are still in the research phase for now. My main reason for stock DME tuning option is retain MAP sensor function of CSL tune, retain the CSL oil level read out in the CSL tune and also maintain emission compliance since we have that annually here.
Items I need some help with are:
- PCV connections from the valve cover to the intake manifold (do i delete the PCV system completely? replace with a catch can setup? how would that routing look on an S54?)
- Sucking jet line connection from intake manifold to booster Y split (get rid of sucking jet line completely and code it out in the dme? what does the sucking jet even do?)
- IACV connection (this i think i have figured out, replacing the snap fit connector at the end of the IACV hose and replace with a hard plastic 90 degree fitting and run a 5/8th hose line to bottom of the intake manifold which happens to have a larger port with a barbed fitting i can use with a hose clamp)
thanks for any ideas you can think of.
