Guys, I'm no stranger to the V3/4 Impreza's but was wondering if its worth remapping (esl or apexi etc) for reliability reasons? Or is the 6s ecu ok as it is?

I was thinking about having it mapped for 95ron with 2 different boost settings.

The car and engine are completely standard apart from a haywood and scott 2.5" decat turbo back exhaust.

Cheers,

Wayne.

I had my V3 STi remapped for a few mods and to help it run safer on UK fuel.

I have an Apexi with four boost setting.

I would get it remapped if its a keeper, gives you that peace of mind that it will run safely on our fuel as on the 6S ecu I wouldnt go below 99ron.

Guys, I got similar problem

Have Classic Turbo Impreza 97/98 with 6S ecu and piggyback at 1.2 bar.
Old classic engine damaged (bearings...)

Right now I have in my hands STI V4 engine from Type-R.

My questions:
1) are my engine wiring harness ready for that V4 engine ? are there any different polarizations ?
2) can I stay on old TD04 turbo ?
3) can I stay on old 6S ecu with old piggyback as it was for classic engine ?

Normally I using SHELL V-POWER RACING 100 (right now they call it Shell V-Power Nitro+).

Thanks for help!!!
