MK2 MG ZR160 Track car
Hi all just jointed with my MK2 ZS but a few people have asked about the ZR track car so here it is......
Started with buying the car in summer 2013 just as a everyday car for £800 as i already had a Evo 7 RS Sprint for trackdays and a MK5a RS2000 Escort i was using on track with the plan on doing some amateur motorsport but i gave up on that because getting hold of good parts was just to much trouble so decided to use the ZR :idea: Few the Escort.... http://i276.photobucket.com/albums/k...psdae3451c.jpg http://i276.photobucket.com/albums/k...ps13a61bf3.jpg http://i276.photobucket.com/albums/k...ps9d5286f2.jpg As first brought.... http://i276.photobucket.com/albums/k...ps464d70bb.jpg http://i276.photobucket.com/albums/k...psc72172b7.jpg Anyway back to the good stuff first jobs were Avo springs, B&G rear camber plates, at this point i wasnt planning on going all out so took her as was to Bedford just for fun.... http://i276.photobucket.com/albums/k...ps294d4902.jpg http://i276.photobucket.com/albums/k...psed8c2e95.jpg http://i276.photobucket.com/albums/k...ps6d9c9240.jpg http://i276.photobucket.com/albums/k...ps8725ede3.jpg http://i276.photobucket.com/albums/k...ps8c1514f6.jpg http://i276.photobucket.com/albums/k...ps466a728c.jpg http://i276.photobucket.com/albums/k...ps17e355aa.jpg |
So after a few months i done a few basic things to the car and as a few friends were going to Bedford Autodrome again i thought i would once again take the ZR....
In the mean time i had picked up a cheap set of rally tyres.... http://i276.photobucket.com/albums/k...psf85d57b1.jpg Put on some grooved disc's and EBC yellow stuff pads.... http://i276.photobucket.com/albums/k...ps6f353844.jpg Made a loom for gauges and added into the ISO loom for radio.... http://i276.photobucket.com/albums/k...psecd68791.jpg http://i276.photobucket.com/albums/k...ps3dd43b37.jpg http://i276.photobucket.com/albums/k...ps7b6e7cd6.jpg http://i276.photobucket.com/albums/k...psd6642194.jpg And off i went had a wicked day and showed my mates how it was done and much to there disappointment the ZR with 109k didnt had any HG faults :happy2: All tho the EBC pads were complete rubbish and after a few laps needed a slow lap to cool or i had a rock hard pedal and no brake fiction and even on a cool day the oil temp was way to high causing low pressure.... http://i276.photobucket.com/albums/k...psc93ebcc4.jpg http://i276.photobucket.com/albums/k...psa7596e30.jpg http://i276.photobucket.com/albums/k...ps13c9123f.jpg After stopping on for a beer on the way home with the boys and the Escort still out of use trying to find parts it was at this point the choice was made to move on to the ZR and cut my losses with the poor old Ford |
After this i went down the move power route and engine rebuild....

Next was to remove the 6 pins i needed from the small MEMS ecu plugs (for fuel pump relay etc) i didnt want to cut up the factory part of loom in case it ever went back to standard etc so i added in 6-way male and female micro JPT plugs....
http://i276.photobucket.com/albums/k...psconec8og.jpg http://i276.photobucket.com/albums/k...psusaksrex.jpg And the finished job factory loom into my loom without any cutting or damage.... http://i276.photobucket.com/albums/k...psql83wqwt.jpg I also fitted flat switch :ohmy: Switch below.... http://i276.photobucket.com/albums/k...psclkggm5a.jpg http://i276.photobucket.com/albums/k...psfzhwoyny.jpg http://i276.photobucket.com/albums/k...pspccnelw4.jpg Quick test to make sure ecu seeing pedal postion.... http://i276.photobucket.com/albums/k...psencrlmfj.jpg http://i276.photobucket.com/albums/k...ps05ffgicc.jpg Repairing the worn out gear linkage and fiting a Dark ice quickshift kit, this was a real pain had to heat and bend in the gear rods as you couldn't get 5th hardly at all as they rubbed really bad.... http://i276.photobucket.com/albums/k...pswbbv30bg.jpg http://i276.photobucket.com/albums/k...ps2xrcljej.jpg http://i276.photobucket.com/albums/k...psowu6pa6u.jpg As so added a remote take off for oil pressure gauge to get it away from the sub-frame.... http://i276.photobucket.com/albums/k...psweyeikav.jpg http://i276.photobucket.com/albums/k...psqduxh9v7.jpg http://i276.photobucket.com/albums/k...ps4dkfjsxl.jpg Putting in the base maps.... http://i276.photobucket.com/albums/k...psazvgnf3r.jpghttp://i276.photobucket.com/albums/k...psi5iu8pfs.jpg I also wiring the in the MIL lamp to act as a shift light.... http://i276.photobucket.com/albums/k...psb0ttr1fw.mp4 And at last all back together for a quick test run.... http://i276.photobucket.com/albums/k...ps0n4ufdt3.jpg |
At this point run into a problem i had a oil leak from the rear of the headgasket, off again then.... :sick:
http://i276.photobucket.com/albums/k...psqcvk2zfc.jpg http://i276.photobucket.com/albums/k...pszb0geb6m.jpg Not sure what happened to gasket.... http://i276.photobucket.com/albums/k...ps0g3rv4h6.jpg And way on went a LR gasket with saver shim, no more leak.... http://i276.photobucket.com/albums/k...psk4a1oenh.jpg http://i276.photobucket.com/albums/k...pscn7ulzck.jpg Mapping next.... http://i276.photobucket.com/albums/k...psqgmedavv.jpg http://i276.photobucket.com/albums/k...pswfkkkfg7.jpg No problems here made stock power but with a fair bit more torque and the car pulled though the rev's a lot better on drive home.... http://i276.photobucket.com/albums/k...psuqclbzro.jpg Next was onto another test day at Bedford Autodrome to test it out as didnt want to go far in-case was a problem, that turnt out to be a wise choice. About 20mins in the engine lost power and was rattling so called it a day and a waste of £160 but there you go. Not 100% sure what happened but the front VVC unit was rattling like mad but after a compression and cylinder leakage test was done no damaged valves to piston ring troubles were found the engine was removed and a Piper 285H solid cam kit was ordered and thats were i am at this point. The plan was to use it with the VVC for a while to give me a bit of time to get the money together to get the full race Piper kit and the steel bottom end, forged pistons etc but there you go. I didnt think it was worth paying £600 odd for a new Rover cam and VVC unit as the Piper kit was £1020 nor did i want to risk using a second hand unit. |
So again engine out....
