MG ZR Track Car #buildthreads

My brother and I had done several track-days in our own cars, but the need to do more track-days was ever growing. We made the decision to build ourselves a track-car that was fun, cheap, easily repairable and could handle some abuse.

Having plenty of experience owning and working on the 3 different MG ZR/Rover 25’s since I started driving it seemed a decent place to start

This build has been done on a relativley small budget compared to some other track-cars you see. Using mostly 2nd hand parts sourced from owners forums and parts donated off a couple of MG ZR’s I have owned previously at various points throughout this build!

So for £150 we picked ourselves up this beast!.
A Rover 25 with the 1.4 K-Series engine

Immediately the light-weighting began!

New wheels

Lightweight car and standard suspension gives some comedy ride height :D

Bigger brakes

Bucket seats

First Track-day… with a whole 105bhp

and then COILOVERS!!!! (at over 3x the cost of the car.. this was a big commitment!)

a little colour coding along with MG ZR sideskirs and front/rear bumpers

After a hunt for more power we managed to source a 160bhp engine out an MG ZR 160
Its the VVC K-Series loved by Lotus and Caterham drivers
(along with sub-frame, gearbox, driveshafts, exhaust, ECU and wiring loom)
a bit of a bargain for £400 for the lot.

Time for the fun part :)

After moving house the Track-car got a little bit of love:

After a year of being off the road the car was given a good clean and put in for the MOT to make it road-legal.

and then it was just a matter of track-days!!

The car handles brilliantly and is a proper hoot to drive. With intake and exhaust mods finished off with a remap the car makes a nice round 175bhp… which is fast enough to be fun…

The car has been parked up over winter. With an MOT booked in for Saturday :|
