Personally having owned a few GTi' over the years, starting with my mk1 Campaign BRM152
That was the car I always wanted when I was young.
Unfortunately I always had too many financial commitments at the time to afford the high price of the BRMotorsport conversion. For me that high torque 2.0 was far more of a fast road car than the standard cammy mk2 1.8 16v.
I did have a 1983 mk1 (not a campaign though) which I gradually took to more or less that spec using Tim Stiles in Bridgwater to supply the uprated parts and getting my local Bosch dealer to fit it and set it up. Unfortunately despite the TSR lads being great guys the engineering wasn’t close to Brian Ricketts standard.
It was a great car, I had GTi mk2 onward from the '80's, but missed out on a mk1. I bought this on a wet January evening in 2009 on ebay with few bidders for just over £2k with 60k miles on the clock!
The conversion alone cost £8k from the invoices!
I sold it as it was a beast, it felt more than 152bhp, in a light car.
The guy who bought it turned up in a Subaru RA, he couldn't believe how the Golf went and paid asking price.
When i say it was a beast it was more like a rapid terrier, it wanted to go fast, far more likely to get you in trouble than the real 911RS it sat next to in the garage.
I should have kept that one!
