Anybody who breaks Imprezas should have some but check the prices first I got mine for £80 (including p+p) off a guy on scoobynet but have seen people charging over £100.
mine made 250 bhp 240 lbft with total decat, equal length headers and a panel filter. must make the next step to a z4. any ideas on the extra it would give with these mods? would rather fit this than the dawes device i've got waiting to go on.
A Z4 will make little or no difference in your case. You'd be better getting an ECU chip (read Scooby ECU) or saving up and going for the Apexi.
If you're planning on keeping the car for a good while and doing further mods, then you will save money in the long run by going straight for the Apexi.
You need a proper re-map to get any real benefit from those headers anyway.
20ps is what the z4 has over whatever ecu you have in the car at the mo so you could say you would get an extra 20ps although you most probably won't.
You could still fit the dawes device after getting a z4 ecu
i think a guy called Scott T posted what boost levels you get from various ecus i'll try to find a copy i've got and post it.
The thing with a dawes device is that it won't let the ecu cut the boost if it wants to (I was told this by a supplier of the device so i don't know for fact)
gc8 - i should have the td05 as i have an import. is that right? unless it's been removed of course. but then i'm the first uk owner and the car appeared to be standard when i bought it.
