In the past diesel engines were never given a second thought
in the tuning world, and in my mind that was until Audi bought out their Diesel
Le Man car the R10. Although some tuning companies had started producing parts
for diesels not many young car enthusiasts had a diesel it was mainly company
cars or the older generation. Until cars like the VW Golf 150 GT TDI, Skoda
Fabia VRS 130 TDi came along. These two are 2 of my favourites but there are
many more out there. The VW Golf TDI 150 has loads of tuning opportunities at its
wheels. The usual Golf Mk4 essentials of coilovers and wheels sort out the boat
like handling and ultra-dull styling. And under the bonnet there’s potential
for adding almost 100bhp, along with upping torque to a tyre shredding 350
lb/ft. remapping a GTI TDI takes power to around 190bhp. Opting for a stage
three setup – including exhaust, manifold and downpipe, hybrid turbo,
front-mounted intercooler, high-flow injectors and single-mass flywheel with
uprated clutch – has up to 250bhp potential. Even a realistically usable 225bhp
doesn’t detract from the excellent fuel economy. The Skoda Fabia Vrs with its VAG diesel enginehas a lot of tuning opportunites.
Its 1.9 TDI engine has been tried and tested to cope with big gains from its impresive,
standard 130bhp. A remap will add about 40bhp plus at least 50 lb/ ft of
torque. Treat yourself to an enlarged air intake, turbo-back exhaust with manifold
and decat, bigger airflow meter, front-mounted intercooler, hybrid turbo,
enlarged injectors and uprated cam, then you could see 230 to 250bhp and over
350 lb/ft torque. To cope with the extra horses you’ll need a stronger clutch
with a lightened flywheel and you’ll want coilovers and brake modifications so
you can use that power without killing yourself.
