So having been on a few trackdays now, me and my brother have decided to buy a car and turn it into a dedicated track car.
At this point I should probably explain that my brother has a thing for Rovers, and has owned 4 over the years. His first car was a 1.4 Rover 25 which was suprisingly nippy (quick video of it sounding tasty here) - which was replaced with a limited edition track-spec Rover 200 BRM, which was then changed for a Rover 25 TDI as he got a new job and was driving 40,000 miles a year. The derv started out with 100bhp and now is running around 170bhp with gaz gold coilovers, Upgraded gearbox with Torsen Limited Slip Diff and Steel-caged bearings, ZS180 brake conversion etc etc
Its safe to say he knows his way around them like the back of his hand.
Having driven his Rover 200 BRM for a few months, I was amazed by the performance of an old rover. The handling was in a different league compared to the astra, and the K-series vvc engine as used by Lotus and Caterham gave a very entertaining ride.
Having got that out the way.. Thats the reason for us deciding to get a MG ZR / Rover 200/25 and turn one into a track-slag.
The plans for the car as follows:
MG ZR bodykit
GAZ Gold Coilovers, adjustable top mounts
Anti Roll Bars, polybushes etc
620ti Brake conversion modified to fit ZR160 discs
MG ZR 160 vvc engine, intake and exhaust mods to around 170bhp (the plan in the long run is to run a set of Jenvy ITB's and an Emerald ECU, but we will not see much change from £2,000)
Uprated gearbox with closer rations, Type B Torsen Limited Slip diff, steel caged bearings
Anyway, on with the pics and interesting bits!
We managed to pick this 2000 Rover 25 1.4 16v up for a costly sum of £150 with apparent Head-Gasket Failure.
The track preperation began!
This will almost certainly be required at some point in the future!
Needs proper suspension
More soundproofing removal
Fitting MG ZR-160 suspension (temporary measure)
MG ZR rear end fitted:
New 282mm vented brakes (next to standard, 262mm solid ones)
MG ZR sideskits and front splitter have arrived
Bucket Seats fitted:
An experiment with a standard 1.4 ZR, vs out stripped out track car:
Noticable difference in a few hundered yards!
After a quick assesment, the car did not have HGF, and it was just an air-lock in the heater matrix which was causing overheating. We stuck an open cone in it and sent it round Oulton Park for its first track-day with all 105bhp!
and a (very) short driveby video on the straight:
and a few sneaky pics of my brothers diesel getting some track-time
Overall we are very happy with the performance of the trackcar around Oulton Park.
The car was so light and nimble through the bends, even though it seriosuly lacked speed on the straights, it was catching much faster and expensive cars through the twisties.
Jobs for this weekend..
Fit the Gaz Gold Coilovers, set dampening and rebound, and adjust height.
Fit sideskirts, paint front splitter
Also need to look at getting a bigger radiator, and increasing airflow to keep the engine cool. Aerodynamic mods etc.
160bhp vvc K-series is the next main expense now suspension is out the way. Expect some moderate power in the next few months.
