OK cool thanks for that.

Which turbos are a straight swap upgrade in the UK turbo. If there is such a thing?

Depends what you want

I got a vf28 cheap ( off sti 6 ) which I might sell soon

Vf 34 / 35 are good

Then you start getting serious ranges

straight swap as in the least mods ? if so just get a hybrid TD04 they are good for 320 and relatively cheap new and second hand.

straight swap as in unbolt mine and bolt a different one in the same place / way, I know there other mods to do, e.g the injectors etc

Bolt it on the limp it or put it on a trailer to map it

just remap the TD04 and use that for a while :) 270+ is still good in an impreza

Very good fun ! Think my mate got 280 on his but it didn't last long

yeah, only reason i ended up doing mine is found the kid who had done the rebuild on it had mixed A+B pistons.

OK thanks for that everyone

Now next question. I've been reading mixed stories about decats and remapping. Some say they ran it without map fine others saying don't put decat on unless getting a map

Now I have a decat down pipe turning up Thursday and I'm fitting Friday. I don't have the cash for a map so will it be fine or not?

will be fine, but will chuck up your eml light

Is there a way of clearing the light?

No light on mine I must have a super cat in the up pipe lol I have a scan gauge that can clear codes but it will just come on again, my friend has a classic and doesn't get the light unless he cruises for a long time don't worry about it unless you're gonna have an mot before remapping

its on  :D drove it for 2 hour straight a 1am to Manchester airport yesterday and no warning lights came on

great news!! :)
