What turbo comes Standard on a 06 plate 2.5 impreza does anyone know if there twin scroll or not just looked at one but can't see any markings on it at all

If type uk sti then vf43, if not on the car you will recognise it by the crack along from the wastegate

Only JDM 2ltr cars are twin scroll.

Depends if you have sti or wrx

So it should be a v43 then ?? I'd of thought there would be some Ihi markings on it but I couldn't see any. What sort of power would a 43 make on a 2.5 sti 10 end in my classic with what supporting mods would it make power quick spooling etc or would I be better off with a vf35

You'd be better with the 35 mate

I thought it was the vf 39's that were prone to that? I've had my vf43 off and there were no cracks.

Been offered the 35 for good money sounds like I'm going down that path then I want 350 from it

I believe the vf43 on a 2.5 will run around 380 bhp but you would be advised to have forged pistons and ARP cylinder studs fitted at that power.

He's putting it in his classic

Still the same engine, just in another car, right?

I have a 2006 2.5 WRX, it's a TD04 as standard so not twin scroll.

Just had a VF34 fitted & mapped by Engine Mapper @Group B. No other mods apart from walbro fuel pump and remove rear cat and it makes 306bhp & 370lbs.
