So I'm getting ready to put some more money in to my 87 TII. I'm going to purchase these parts:

Already have
fresh build from Atkins, stree ported S5 (with S5 peripherals) with S4 front cover
with S4 harness and ECU
I'm going to send in for the rtek 2.1
I'll be buying:
four new 720cc injectors (reccomendations?)
FMIC

I'm looking for a plug and play install, with reliable results. Anyone see any problems?

 

Sounds fine except for the S5 peripherals part. If that means S5 electronics, such as the TPS, AFM & boost sensor, it won't work with an S4 ECU.

 

ok, here's some history.

The car runs with an S5 block (S4 front cover), with S5 turbo and turbo manifold. It has an S5 Intake manifold with everything removed/blocked off. I'm not sure of the electronics, but the throttle body is modified per rotary ressurection's emission removal. The car uses an S4 ECU.

The engine is mismatched parts with a reman, ported Atkins block.

Hopefully that makes sense.

 

Well, if it's already up and running, you'll have to be using S4 TPS, MAP & AFM. So, you're set.
