Porsche Boxster 986 - engine swap project
Discussion
It's not a great picture, there are loads of resistors and capacitors that have fallen off, it's definitely ruined. I've got all the maps saved on my laptop which I did rescue from the fire so if I can afford to rebuild it how it was before I'll be able to get it back to the point it was at before.

I initially bought a V8 RS6 one but it was just too big to fit so I've (I try and avoid RS4 bits as the RS tax on everything is mental money). I've mounted it upside down and it's still a pretty tight fit.

How big is RS6 trottlebody in mm diameter? I may also have some claerance problems. The trottlebody from the abz is Hugh. Trying to modify it, but maybe i have to go in a different direction]
I want to resurrect this build if possible. I nearly bought a non running Boxster S for £2000 this weekend but the guy selling stitched me up. I contacted him on Thursday and said I could come that evening, Friday evening or any time on the weekend. He told me Saturday midday and then sold it on Friday.
I've taken the engine out of the A6. I forgot just how much crap there is on them.
I was looking at the standard turbo's and wondering if I should retain them. Before I ditched the Porsche shell I realised that if I was going to re-build it I might not be able to do it like it was previously, going by memory of where the standard turbos fouled the chassis when I offered up the original engine I took an angle grinder to that spot to see what's behind. It wouldn't be a big deal to cut and weld it up for clearance. I also thought about a hack job intercooler install so cut the boot lid up (very badly!) to give me some sort of idea.
I recently watched the video of the 1200bhp Mclaren with 3 turbos and it got me thinking I could make use of the standard turbos and I could rig up the exhaust to run to my rear mounted turbo and have it running 3 turbos with a compound set-up same as that. The standard K03's make boost by 1500rpm. All very much pie in the sky at this stage but it'd like a crack at it.

My advice would be to go with one or two turbos. If you have room for them, a pair of RS6 turbos would be great or you could probably get a secondhand set of K04s from someone fitting bigger turbos to an RS4. I used to own a B5 RS4 and the engine was brilliant (so much better than every other aspect of the car, apart from those arches), pulled from fairly low-down to the redline brilliantly. I believe the S4's engine with the RS4's turbos, injectors, throttle body and probably a few other bits is good for 500 BHP. Then you'll have something that is known to run nicely together without having to worry about oil returns, etc. Having said all that, I'm a bit confused about your previous post and whether or not you have the room to use side-mounted turbos.

I agree go for upgraded turbos in the stock location! TTE offer turbos upto 950PS for the RS4 these days (guessing these are modded k04's). That way you know they will probably fit with the cutting that you have already done. Interesting location for the intercooler. Similar to the noble M12. Might be worth checking out what they chaps have done to ensure descent airflow. Are you scrapping the air to water setup?
I don't know if I'm scrapping the air to water yet. Probably not, just looking at different options while I had the old shell to cut up.
The majority of my a2w setup has survived, i'd just need the radiators and the pipe work. I'd have to do something different for the radiators this time as the Hybrid Cayenne ones are expensive and rare.
