Marcus Posted March 17, 2015 Posted March 17, 2015 Hi all, I've been considering multiple engine swaps recently and have stumbled upon the information that for a small period the mg ZT and rover 75 used a low boost turbo k series engine (see attached image). I know several people have done t series transplants for big power but no one seems to have tried a k series turbo transplant. The standard motor only has 160bhp but a t25 turbo bolts straight onto the standard manifold and with some minor tweaking should be close to 190-200bhp. I know this is achievable with an NA engine, but this will be a fairly low stress setup with a nice amount of torque. My main concern at this point it - why has no one done this before?
russelld Posted March 17, 2015 Posted March 17, 2015 No room for the blower without cutting a hole in the bulkhead ?
dobbo Posted March 17, 2015 Posted March 17, 2015 There is info on SELOC about a K-series turbo. For me, the two issues are 1 - can a K take a turbo (reliably) and 2 - do you want a turbo even closer to you (through a modified firewall) ??? What power / torque are you after ? It's easy enough to get to 200+bhp and 150lbft torque with a NA K-series. If you want more, you need to look at the options. T-series (turbo) K-series (turbo) Duratec NA (I think) Honda (NA or SC) Audi (turbo) The last 3 have commercially available options. No-one has done a commercial option for the T or K. I think there's probably a reason for that.... One thing I've never understood is why the Toyota or VXT engines (and subframes) have never been tried in the S1. Does it just not fit ?
Alex B Posted March 18, 2015 Posted March 18, 2015 Chris, I think the reasoning behind not trying the yoga lump in an s1 is its a lot of work and the k20 is a stronger engine. A vxlump would be interesting. Although you missed one potential option off, K series with a supercharger as this does has a commercially available option.
DeanB Posted March 18, 2015 Posted March 18, 2015 Wouldn't keeping it cool be an issue, bearing in mind it is mid mounted with undertrays? I know Lotuz struggled a bit to keep the VX turbo cool enough during it's development.
@ndy Posted March 18, 2015 Posted March 18, 2015 Don't waste your time on a turbo, Stick with a NA K-Series, they are great engines but I am biased......
