I found myself a 13bt motor j-spec but it has no ecu..

Will the N/A work? Or do I have to find one?

 

only the N338 ECU that came with the 'verts will control both a S4 13B and a 13BT.

Since you didn't say what year/series motor and what year series car it would be hard to say if your ECU will control a 13BT.

There are people that do run a NA ECU on a Turbo, however the knock control, timing control, boost sensing and maps are not correct.

 

Congrats on the find!

Would it be possible to get a group buy on this?

If you don't mind me askin', how much is this running ya? Might be interested in more power. :P

 

I am going to check it out next week
but 900 canadian for everything but the ecu. It is a S5 j-spec motor. My car is a 90 N/A

As for group buy. I really doubt it. I can see what else is around whenever I go out though.

I keep ending back at square 1.

 

Well, good luck, and I hope ya get things worked out!

Oh yeah, and I killed the accord.

 

Serrious. Strange...Why'd they put that in the vert only?

 

I was told that both the S4 Vert and S4 T2 use the same map which is optimised for power with lower emissions.

 

Nope your ECU will not work you will need a TII fuel pump, N370 ECU, a N370 boost sensor, and the knock sensing comp that is high up in the dash on the passenger side kick panel. Other than that sounds like you have everything else. Oh yeah I forgot about the TII transmission, drive shaft, rear end and 1/2 shafts. If you want to use your NA transmission you have to use the S5 NA Flywheel.
