I am rebuilding my motor soon on my s4 tII, and i'm on a bit of a budget for the time being. I want to port my engine, and i know i will eventualy buy a larger turbo and move to a haltech. But for now i was wondering if it was possible to run my stock turbo and fuel set up. and if it is not possible what mods will i need to make this work if it will work at all? Any recomendations?

Oh yeah, Happy thanksgiving guys!

 

you can run stock boost and fuel on any port work...Now keep the boost at stock levels will be a different issue.

 

well, what i meant was that i wouldnt have to get a new fuel pump or anything? or would the boost rise enough that i would need a fuel pump or injectors or somthing?

 

If you keep the stock exhaust the boost shouldn't raise up too much. Just get an a/f meter and a good boost gauge to make sure, though.

 

i run the smae setup at the moment, i have a large streetport and stock turbo and fuel, only i have custom exhaust. my boost spikes to around 13 pounds but it doesnt go lean. i plan to upgrade the injectors to 750s all the way around and use an rtek 1.8. but you should be fine, i would upgrade the fuel pump but i dont think you have to. mine is allready upgraded.

 

with that restrictive stock exhaust you will have nothing to worry about.

 

you like blowing up engines aye?

 

i already have an rb downpipe and 3" single tip custom exhaust. so do you think my boost will spike too high for the stock fuel settings? does this mean i'll need a fuel pump and pressure regulator? or will i need more to make this work right on stock turbo?
i'm guessing i'll need a boost gauge and air fuel gauge too huh?

 

if you give the wastegate a hearty port then youshouldnt have any problems, just keep an eye on the boost gauge or, dont put in a FCD so you hit fuel cut if you over boost

 

would an rtek 2.0 be a good option to keep control on the fuel and stuff?
also, i just read a thread on porting the wastegate, thanks for the suggestion. seems to me i should have already done that.
anyone have any other suggestions?
this is my first rotary and i'll need as much as i can get. haha.
