Basically as it says, I've got everything to do an S5t2 swap into my S4 NA chassis however the harness on the driver's side isn't fitting into the t2 ecu (n337 I think?) and I've talked to japan2la and some other guys and its not looking so good. they say my options are, a) change the driver's side harness which I hear is a bitch, b) Make my S5 into an S4 by changing front cover, harness, ecu etc or c) run a stand alone. (japan2la reccomended a microtech which sounds good but **** thats commitment)....I just need to know if anyones gone this route or run into this problem or some honest opinions...the standalone isnt so far fetched but on military pay scale its going to be a month or two before I can snag one. Let me know and I appreciate everyone checkin out regaurdless if you can help me or not.

thanks!

Ya, your supposed to stay within series when swapping from na to t2. Otherwise your looking at long hours of wiring. I ran into the same problem you have but I pushed the easy button and got a haltech. Have fun.

 

microtech LT10 it

 

I'm thinking I might buck up and go that route. Usssss princeton, do you run one of those?

 

also being that I've always and always will run premix would I have to change the front cover?

 

If you're using premix and not using an OMP then you shouldn't need to change the front cover. The oil return for the turbo is in the same place on both engines. Just make sure you block off the OMP flange on the cover if you aren't going to use it.

 

i did the S5 t2 into s4 n/a swap, i used a haltech E8. doing it any other way is a serious waste of time. you'd spend forever messing with stupid wiring and its not worth it.

 

If your going to use the difficult button, then you will need to hook up the s5 omp, the ecu goes into limp mode without it.

rotaryresurrection- if ur swapping an s5 T2 into s4 do u have to change the water pump and the water pump housing also

 

Depends on several variables. You havent mentioned whether you are running the stock fan or not, which radiator you are running, etc. Generally, I would say no.

Why do you seem to think it's my responsibility to answer you? You already sent me duplicate email and pm's about the same stuff, and frankly its hard to read your writing and you give very few specifics that can affect the requirements.

 

alrite well i have the s4 na stock fan and i have the s5 T2 stock fan (prolly using this) and im going to be using the s4 na radiator which has the cap on it and so i dont have to change over the water pump and the housing, is that rite also i didnt know it was going to **** u off that i ask these questions but i just really need some help rite now and it seems like u have the answers to my question.

 

IF you use the s4 rad, you cant use the s5 waterpump/housing/neck because then you cannot fill the coolant all the way up...the radiator sits lower than the engine. You cant use the s4 thermostat neck on an s5 water pump housing.

If you get an s5 radiator you can use the s5 housing/pump/neck/fan and be good to go.

I guess I just get annoyed that I seem to be the go-to guy on the entire forum for answering questions about people's screwed up swaps. I don't do cross series swaps, and I dont recommend that anyone else do, but people still bring their problems with cross series swaps to me anyway.

 

sorry man. I should have checked your site before purchasing this beast. Ahh whats done is done... hello microtech. thanks <3
