Freelander k series turbo conversion

I'm looking at a few possibilities for a project and thought of the Freelander and as the title says maybe a Turbo. I have checked and can't find any info or anyone who has done it, can't say i have even looked under the bonnet of one but assume plenty of space. I would probably go for an early (read cheap) one so wondered what year mems3 was used so could go with a Z&F remap, anyone done a mems3 conversion, what sort of power can the drivetrain handle, as you can see loads of questions anyone have any answers.

my first thought when i saw your post was..."if a k series struggles to keep its head gasket together as std how the hell will it stand the pressures a turbo will produce"
my 2nd thought was..."good luck...you may need it"

The k series gasket issue is down to thermal stresses on the engine
i.e the cooling system is the culprit rather than cylinder pressures.

a 270Nm remapped turbo might be pretty useful in a Freelander..

That was my reasoning, turbo grunt Rather than revs just not sure what the drive train can safely handle and as said the k turbo is fine if used within its limits

I looked into doing the same thing a while ago. From research and word of mouth, i'd be more worried about the HG than drive train. There is a KV6 version of the Freelander which will be putting the same torque out as the Z&F turbo map.

People have done this to ZR and ZS's using standard 75/ZT parts and re-mapped ECU's.

Also allot of Freelanders have the PRT thermostats which reduce thermal shock.

Could always an oil cooler.

Just found out that the Freelander changed to MEMS3 in 2001 so if i go for this looks like i need an 01 onwards so save a lot of hassle

I did actually think of that, would have to use an early L series Freelander gearbox so very do able, also looked at converting the V6 to manual which would make an excellent motor but i think turboing the K series is a much more straight forward job and something i can't find that anyone has done before

i hear you and i had a 414i k series a hammered it all over for 3 months red lined it broke gear box mount speed stopped working even a crash 100% not my fault only did this sort of abuse on private land anyway the thing never died didnt miss a beat dust getting me hooked on rovers. every one said it would blow red lined it for a full 5mins still nothing but 50/50 and if you make the uprated gasket and rethink and upgrade the cooling maybe even over kill on the cooling it may be a good engine when turbo'd

Why? they made a turbo k series.. and still pretty much do. just make sure you can keep the thing cool and you wont have any problems.

Found out some more info, the fuel system on the Freelander is the same as the 75/ZT 1.8 turbo ie it does not have a fuel return to the tank so I'm assuming the compete turbo engine and inlet manifold will bolt straight in. Also the fuel pressure is 3.5 bar, is that sufficient to run the turbo lump.

Go for it the most simple conversion you could ever do its litrially the same as an engine change with changing a few bits, sorting out the down pipe, getting the ecu done and doing the pipe work for the intercooler simple But I would use the gear train out of the v6 as it is uprated a fair amount for the extra torque the gear box Is the same apart from the final drive is increased in the v6 but the transfer box is uprated a great deal in the v6.

The V6 box wont mount to the K series.. An ordinary PG1 will take all the torque a K turbo can throw at it, and then some.

The KV6 in the freelander only came with an auto box, which is shame as i think a manual version would have been excellent. What needs to be done with the wireing to fit the turbo lump as i want to start sorting all the bits and pieces out first as its going to be a while before i buy the car

I'd be more concerned about the condition of the viscous coupling, ird and rear diif, they need to be decent especially the vc

This is why I said the gear train e.g the Transfer bx etc. And There are a fair few manual v6 free lander's Many have been converted and I think some ex demo cars came with manual ones.

true you did mention the ird but a worn vc can wreck both the diff and ird, it would be a massive shame to see a good idea like dropping a turbo in a hippo if the vc wasn't up to scratch. I had half a mind to try a vvc lump once but i read the engine management would be a problem.

We have already supplied an upgraded ecu for a vvc Freelander, the set up is quite simple

Do you have any links or further info on the manual conversions as I've scoured the net and not found any trace of one that's been done, be interested to see what's involved.
