Aaron -
First off, great site, tons of excellent information!!! Definately in my favorites. I am building a turbo 6 port (obviously).
The set up I am considering is as follows:
-s4 6-port
-turbo rotors
-large street port
-Remove exhaust diffusers? (worth the work?)
-TII ECU With Rtek 2.1
-Port matched TII lower and upper intake
-550 or 720 primaries, 1600 secondaries. (did I read that you use ford injectors?)
-Holset HX35 or H1C turbo (basically same turbo, not sure what size hot side I want to run yet. Open to suggestions)
-FMIC
-Big wastegate (Tial probably)
-Can you suggest a good company to get new apex seals from?
-Big fuel pump (holley blue or walpro 255lph)
-3" custom downpipe and full 3" exhaust
-I also have full TII drivetrain.
I think that about sums it up.
Hoping for 350ish HP?
Will this set up work together?
Thanks in advance for your feedback.

Scratch that. Just pulled out the n/a motor (which had a blown seal) and one of the housings is trashed.
Going to put in a TII motor now. Set up still sound ok with a 4 port? |

I really don't know anything about the Holset turbos and have a real hard time finding specs for them, so I will have to trust that the turbo is sized correctly.
Can the RTek handle 1600CC secondaries? That's a bit big for 350HP though. 720CC primaries and 1000CC secondaries are fine. |

the specs i can find on the turbo are as follows.
h1e: 60trim compressor, 22cm hotside puts it around 1.05 A/R i think.
this is equivillant to an hx40.
Also, i did some more research on rtek. seems as though they can only handle 720 secondaries. probably going to need a standalone. i really want to see 15-20lbs of boost. i have never heard of any piggybacks that can handle that. what kind of unit do you recommend?
with a solid tune do think 400 hp is unreasonable? by the way, this is not a daily driver. i really appreciate your imput. |

I forgot to mention that about the RTek, but I had figured they finally updated it...
Why do you want to run 20 PSI of boost? That's a lot of boost for pump gas and it would be far better to pick a turbo which is efficient around 15 PSI instead of 20.
Sounds like you are looking at a 400HP turbo there. |

New to the forum, I didnt want to start a new post so i figured this would be a good one to ask my questions.
This is my second RX, its a 91 N/A and i really want some boost! lol
Ive been doing my research for a long while now and just wanted someones opinion for this setup. not sure if this is a good place to post it, like i said, very new to the forums so dont rag on me, just point me in the right direction.
-s5 turbo and manifold( and spacer)
-t2 injectors(secondary or both?)
-Fab the exhaust with the bonez CAT
-Probably some ebay special for an FMIC and piping
-S-AFC controller
-EGT Gauge
And obviously odds and ends like oil lines, vacum lines, Boost gauge, ECT.
I dont want to go crazy with boost(especially being high compression rotors) and only plan on running about 8 LBS. just wondering if this would be safe enough for a daily driver?
Also, im new to tuning and was wondering how hard it is to use the Apexi S-AFC? Or if it would be better to take it to get it tuned since im fairly new to tuning instead of F@$%ing things up :)
Thanks guys

I've not done any sort of work on turbocharging the S5 engine because the compression is so high. On the big forums, others have had working setups but they often don't last very long.
If you go with the S5 NA engine, then two things will help:
1. Full standalone. The ignition timing in the NA S5 ECU is far too aggressive to run boost. The S-AFC will let you throw fuel into it but you are still dealing with a high compression engine and 30 degrees at WOT...
2. A better turbo then the stock turbo. It's horribly inefficient. A turbo designed in this century will heat the intake charge far less. Now at 8 PSI it probably won't be a concern, especially if you use a large intercooler.
If you can, fab up a proper manifold instead of the spacer. If you can make the spacer, then you can make a manifold. The advantage is that you can move the turbo out towards the front of the engine, and keep the aux ports functional. As well as avoid interference with the frame rails. |

Thanks for the response.
Im still debating trying it on the s5. Although getting the standalone kinda throws my budget plan out the window, id rather do it the right way.
At this point id almost be better off just doing the swap, I just dont feel like destroying a perfectly good N/A. I need something reliable and with the luck people have had with it on the s5 keeps me up at night lol. but ill keep ya updated |

| Sounds like a full TII swap is the best idea in this case. |

Good Setup For N/A Turbo?
