Hi, Just signed up as I know there will be a lot of people here who know this inside out. I've read a lot about the various options here and elsewhere but the more I read of all this general info the more it gets muddied up. If we forget any issues of fitment, plumbing and custom downpipes and just focus on the engine and turbo that'd be cool. The criteria is oddly specific as I would like to be at the lower end of the 300bhp to 400bhp bracket on a stock *sized* 1.8 AGU with a near stock rev limit and some rods in the mix. To get it out the way first, K04 Hybrid. Eevery time I see one mentioned it's maxxed out and has WMI and this and that. That's all good and there are some impressive cars about, Badger5's Lupo and so on, but without Meth and without a need to go much past 300bhp for example, would EGTs still be mental? Either way, I come back to the usual worries over cracks forming and the tiny housings naturally lending themselves to getting hotter than hell... So that leads to the next option which would be a Garrett. I like the idea of a 2860 but I'm not sure if it would run out of puff for trackdays? If that would, a K04 Hybrid sure would, so kind of a mute point I guess. Next in line seems to be a 3071 as you're not sacrificing hugely in the lag department, yes there's a chunk more, but on a track with a gear stick at your disposal it is what it is, but with way more headroom. I think being honest that a 3071 would give more power than is required, I have a lightweight FWD A3 and will use it at Thruxton which is relatively wide open. Would exhaust valves want to be included if it went this far or would it be no more (or even less) of a concern than with a red hot K04 Hybrid? Interested to hear the opinions around on this. What did you go for or what are you planning on going for? Thank you!
