Just in case any one else wants an 82mm TB set up for $180
Got mine going today, works great, no hiccups (lucky me).

Well apparently the adapter plates aren't even needed! You can just wallow out the holes in the 82mm TB and bolt it right up. Good info (not mine).

Excellent stuff here, thanks for sharing

so if you go this route do you still have to pull the SC off too ? or can the TB be swapped in place ? |

Flow restrictions are cumulative though, you can upgrade the throttle body and Y pipe and leave the 1/4" long section of 74mm on the snout and it will still flow better than 3" long section of 74mm Y pipe, TB, and snout. Only thing I'd be a little worried about is if the actual airflow does something a little weird hitting that 74mm lip downstream of the TB, but probably not. You could always put the 82mm on and see of it feels. When ever you get a chance take the SC off and bore the snout. Replace all gaskets when reassembling. |
anybody know if this would work for n/a m113 engines?
|
do you think maybe some sort of cap can be 3d printed to be placed inside the snout for boring to prevent particles from falling in?
how deep does it need to be bored inwards (width is 82mm but how deep does it go)? |

I have an 80mm but need to do the pin swap. Need to find a harness and wiring picture somewhere.

The stock e55 works backwards to get the oil breather hose behind the blade where there is alot of vaccume at idle with the blade almost closed.
The problem with porsch and audi tb is some don't have a hole or some have the hole in the wrong spot. The oem 550 82mm tb has the breather in the same spot as the stock e55. After I tapped that line behind the blade like the stock setup my tps went to 2.7% idle just like stock and no more codes. Its nothing secret about it.iv had about 10 people pm me about there bosch tbs throwing codes. I swapped pins 1 and 4 and 2 and 3 on my amg tb. Look at how the stock e55 is setup and you will see why you get an idle to high code.its because of the oil vapor hose that needs to be behind the blade at idle.if you give that hose air the idle goes up like crazzy.try unpluging it on a stock car and watch your 4k idle lol Use this search to dig around a bit more on the subject (I always use google instead of the forum search, much better): https://www.google.com/search?client...%3Ambworld.org Good luck. |
Oh here we go, got a winner I think:
