This as been probably been asked a thousand times but what petrol whould be best for a 96 wrx import only ever used standard 95 octane but was wondering if 97 would be better.

Thanks robbo

You really should not be using 95 octane fuel in a import!

tesco99 ron or v power you will have early detonation off engine using 95

97 + octane booster until a change of ecu and remap.

97 is perfectly fine for early wrxs.
Check the ecu,passenger footwell underneath the carpet and a there should be a kickplate have a look it should say Z4 (if it's a saloon) open it up to see if there is an extra chipset (bottom rhs of this picture) if there is it will most probably have been fiddled with.




Octane booster is a waste of money unless the car has been chipped/remapped

yes your ecu and turbo will be different to a saloon BUT will still be fine running on 97 ron petrol (BP ultimate doesn't seem to agree with imprezas though)

I know my turbo is a TD04 I have a TD05 ready to fit when l can find a good mapper in manchester area.

My local shell garage is being refurbished so i got stuck with a tankfull of BP Ultimate 97 , as myblackwrx has already said my car ran noticably badly / roughly , its a my96 jdm sti wagon . Now back on the good stuff from shell and an ecu reset .

i got mine done by andrew carr (hes from preston but mapped mine in irlam) yesterday and i absolutely love it the car now pulls like a train. he charges £300 for the first map and about £120 for tweaks

robbo68

Hi all do you have a number for andrew carr so l can give him a buzz.

My ecu says 3B on it l do have a spare ecu that say's Z4 on it this came from the same year 96 classic saloon will it work on my WRX wagon both are 4 connector units.

robbo68

What will it do to the TD04 turbo if l fit the ecu first ????

Cheers
