1993 Suzuki GSX-R400 Turbo
Owner: Chris Jennings Owned for: four years So far: home-made turbo conversion What’s next? final build and setup
Ibought the bike as a frame and engine, with the plan to use up various parts left over from other builds – I call it the ‘Gixxer Bitsa’. So it has an RG125 front end, an FZR1000 swingarm with an extension added, a Ducati 600SS rear wheel and caliper, a Bandit 400 shock on an SV650 linkage, and a fuel filter from a Massey Ferguson tractor. The seat unit is Z400, and the numberboard is from a Royal Enfield.
It’s currently apart for final paint after a dry-build and an initial dyno run – I’ve been fighting hamfisted owners drilling holes in everything (including a botched exhaust stud that peed oil out), and mismatched components stopping it running right. It works fine up to 5000rpm, but the next job (once the paintwork is back and it’s back together) will be getting it to transition and run properly on-boost. Then I have another engine to experiment with FZR600 pistons, which give more capacity but also lower compression to run more boost. An Ignitech programmable CDI is a consideration, and maybe a bigger turbo later…
It’s a bitsa alright – fuel filter from a Massey tractor – if you please
niced-up now RG125 forks have you and what with paint
Engine might get a capacity hike with FZR600 pistons
