940 with T5 power..

Is it possible on a 95' 2.3T auto... I think it's roughly about 170ish hp (I think) just now, but I'd thought about a remap and (possibly if needed) the T5 turbo itself, but obviously I cant use the T5 manifold.

T5 turbo? Oh yes, big fun warning! 

Yep, the T5 turbo will fit - its one of the easiest turbo swaps around if you can fabricate a bracket. You'll need a *conical* outlet mitsubishi td04hl-15g turbo from a 1995ish T5. You can use a flat outlet turbo as fitted to later cars, but you'll have great difficulty in making the turbo-downpipe joint airtight - not a problem if you're fitting a new downpipe! The procedure is described here - Note that the important issues are 1. oil feed orientation 2. wastegate actuator bracket. If you can fabricate the bracket (needs to be sturdy) then its an easy job. As you already have a 13c turbo fitted, you have the coolant/oil feed lines already - although I'd highly recommend getting new oil feed lines to avoid the possibility of carbon shards coming loose inside the oil lines and doing bad things to your new 15G turbo... I would HIGHLY recommend that you get a larger bore sports exhaust and thro-flow cat - 2.5inch system dia minimum - in order to prevent heat issues. The 15G can flow much more air/exhaust with the downside that it generates more heat. Oh yes, also use fully synthetic oil, again due to heat issues. If you haven't got an air/fuel mixture meter, I'd fit one - as the maps are designed for the 13C turbo, you have a real risk of going too lean at moderate to high boost, resulting in melted pistons. Depending upon how much boost you're going to use, you may need bigger injectors and a larger intercooler. In summary, fitting a 15G gives some pretty impressive returns for a road going car, but there are risks if you don't think the whole thing out carefully. The upgrade needs to be balanced in order to retain reliability. Oh yes, just in case you're wondering, the 15G spools up almost as quickly as a 13C - the 'G' indicates dual pattern compressor vanes. One set are optimised for low rpm/quick spool up, while the other set are good for high rpm boosting.

As long as you did not intend to fit a T5 engine to a 940. It is a very costly mod as you have to find the right bellhousing to match the FWD (east-west) mounted engine /gearbox combo with the RWD (north/south) engine/gearbox combo, and the sump may need changing to suit the different mounting direction. The engine mounts may need to be re-engineered as well (T5 mounts on a sub-frame). All the best, Peter. :car-smiley-031:

I didn't read it that way Peter - but I think you could be right! Wow a full T5 engine in a 940... lighter, smoother, more economical, but more complex, more fragile (arguably), and I daren't guess what the insurance would cost :) Thats a pretty major conversion whatever way you look at it. I'm sure some US/Swedish enthusiast has done it, but I for one wouldn't dream of attempting it.
