I am currently doing an S5 N/A to the S5 TII Jspec swap and had a few questions and things I would love to clarify before I went on and made any mistakes.

First the clarifications since they're easy. The engine I bought came as a complete swap so the engine, transmission, uncut harness, ecu .. that kind of stuff.

1. I need an S5 Fuel pump, AFM, and the N370 pressure sensor and that's about it that needs to be converted??? (I am not riding it hard so I am holding off on the rear end conversion for now)

2. The N/A harness is easier to use and only the knock sensor and duty solenoid need to be spliced in and also there is no 5th gear sensor so there are only 2 plugs instead of 4. (Not sure on this one since i've heard mixed opinions on the harness)

3. The fuel lines are reversed.

That's about it for clarification so far the swap hasn't been too difficult but I my biggest problem had been trying to figure out an air intake setup. I'd like to have a **** pipe run from the turbo out a bit then put the AFM on and then a performance filter and I was told this is doable but nowhere have a seen what to do with a couple of hoses. I have a few pictures as a visual aid and they are too large for in this post so just follow the links.

4. Hoses 1 and 2 used to go into the stock intake if I am correct, do they have to be hooked back up into the intake between the turbo and the AFM or what have others done with these hoses??

5. Hose 3 leads to the air control valve and I read somewhere that this can just be plugged like it is now but wanted a confirmation on this because i'm not sure.

6. also I just wanted to double check that hose 4 which has the BoV going into it hooks up to the ... pressure sensor??? not 100% sure on this.

Thanks in advance for the help guys, hopefully I can get the new engine in by next weekend.

Cheers.

1. TII fuel pump (S4 & S5 are the same), or better (FD, walbro, etc...) & a custom driveshaft w/ TII yoke and NA diff flange. Mazdatrix makes them, or you can buy an auto NA shaft and get it extended ~2".

2. Always use the NA engine management harness. A TII harness (especially a short JDM harness) is a waste of time, and much harder to adapt.

3. Don't just reverse them from what you see on your NA engine. Make sure that the feed line (w/ filter) connects to the hardline that runs to the pulsation damper (no vac hose) & secondary fuel rail. The return comes off of the primary & FPR.

4. Yes, they connect to the stock intake tube. Get some NPT screw-in fittings if you make a custom TID.

5. Normally connects to the air pump. Since you don't have one, you can remove the hose and metal tube that run to the ACV, then put a blank-off plate on there if you have the capability to make one. Some 1/16" sheet metal, a hacksaw & a drill will do it.

6. That hose/nipple normally run to the boost sensor. The BOV doesn't need to be tee'd in like that. It has it's own nipple above the ACV. It has a black rubber cap on it, in the picture.

For more details click the link in my sig. It's mostly S4, but there's some S5 info in there, and a lot of it overlaps.

Thanks, ya I was really confused as to why the BOV was connected there and that's what made me second guess it.
