?? Is its possble to use an aftermarket TB with the DBW??

 

Yes and no, there are companies that will bore out your stock throttle body and put in a bigger butterfly. But other than that I don't believe there are any DBW aftermarkets available.

The stock TB is not a bottleneck in the s2k. The stock TB moves as much air as the head can handle without FI. If you turbo or SC, then a larger TB might help.

 

I think AJ Racing sells a larger diameter TB for the dbw cars on their website. I plan on getting one when I go with the SC.

 

Spoon has 70mm DBW TB... there was a group buy even

 

Spoon makes a throttle body for DBW cars.

 

Agent! How are things in Estonia? I always wanted to travel there when I lived in Germany. Kind of glad that I am not there right now though, bet it is seriously COLD!!

We have done several throttle by wire throttles. We've seen gains in the 2-3 hp range for NA and 8-10 hp for even mild forced induction (ie. base Comptech kit). You can see this on our website:
