Hi all, as above I have a 98 impreza turbo, running a td05 hybrid turbo,turbo back exhaust (decat) hks filter, 255 fuel pump,fmic, 380cc injectors, my block is a EJ20, with the gear box from a 2005 wrx sti.ty754 with longer 3rd gear

I am just wondering what people think it should be running on these mods I'm not sure if it's been mapped it was running standard fuel pump which I found strange with the td05 and fmic

I'm not sure if the injectors are up to the task they're the grey ones as it seems a little juddery under full acceleration like it's restricted

Just looking for advice in my mind I think yellow injectors and a map may be the answer

answered it your self mate. map will make a world of difference and yellow injectors 440s will get you past 300 with no probs

Thank you mate just thought I'd ask the experts can I ask what bhp people think this set up at the moment should be running?

If you get the yellow injectors you should easily be able to max them out at 350 bhp with that spec, get a decent feul pump fitted

Can I ask what fuel pump any of you recommend? I know the 255 is not the best.

The 255 is the minimum you'd want,I've got a 255 walbro(unknown age) but am going to replace it with a brand new walbro or possibly a Hrc, if going for a walbro there are some fakes about on ebay so get one from a trusted seller

If the old owner didn't bother mapping the car I'd be assuming you have a standard td05 turbo to go with the standard injectors, unless you know for a fact it's been hybridised
