s4 na to s5 or s5 na swap?

[Fidelity101]

the efi/ecu harness came with every sensor but the air flow sensor, ecu, TPS. I have an s4 one but I know I will need an s5 one.

I know I can't just swap the cluster in, worst case scenario I have to re pin it.

My gauge cluster is fucked, I'll post a picture of it later. besides that the accessory gauges don't work on it except fuel and volts.

basically I need a new cluster regardless, might as well get an s5 one, it would be easier.

I'm short the logicon and the dash harness, I don't have a stereo or anything and I rarely use my HVAC controls, mostly will just keep it on defrost.

I could probably run 2 ecu's and have the S4 one control the dash/hvac controls.

and this is what I'm prepping for my car right now, I got to down to keg + flywheel



got all that for 500.

I have a RB AL flywheel but right now I need an s5 counterweight, I cant grind the s4 one down to the s5 weight spec unfortunately.

I got all winter to do everything so that makes it better, however I would like to get it runing for the winter so I can take it through the snow but there is always next winter.

but will I need an s5 starter too? I hope not

I'm going to run premix so I will just make a block off plate for the front cover and use the s5 front cover, also going to get rid of the extra main pulley ribs that I don't use, ie PS and AC.
