Results of the remapping & dyno session of the Giulietta QV TCT are in: 305 hp / 418 Nm. The torque curve has been capped off to save the TCT transmission, this results in a flat torque line between ~2500 and 5000 rpm. We initially hoped for a little higher horsepower figure, but the good thing here is that it keeps making good power up to 6600 rpm. The maximum power is actually flat between 5900 and 6500 rpm. This flat top could be the indication of a flow restriction, likely soot buildup at the intake valves which is a known issue. However, coming from 240 hp stock, the performance difference is huge, and with the TCT software modded for faster shifting times, this QV goes like a bullet now! ... See MoreSee Less

Giulietta QV TCT in for a performance upgrade package. Basically the stock 1750 TBi engine is restricted by three important things; exhaust, air induction and intercooler. This QV had the middle silencer and centre pipe replaced by Ragazzon pieces. Since these are stock diameter, these don't add performance, only sound. So these were removed together and a completely new stainless steel exhaust was build, starting with a 76mm turbo back pipe, sports cat, 64mm catback and Ragazzon backbox with the reducer connection pipe not fitted. Further our intercoolerkit was mounted and a proper cold air intake system with a BMC DIA airbox.
As we've seen before, this hardware has the potential to deliver well over 300 hp with the stock turbo. Tommorow H&S Corse will complete the job with a remap and dyno session, so stay tuned for the results!

Another power conversion for a 166 2.4 20v euro 4. As we stated earlier, the 2.4 JTDm 20v (euro 4 without DPF) engine coupled to the 166 is one of the most desirable combinations. However the stock exhaust system is made very small (we measure 48mm ID at the centre CAT entry) which creates too much backpressure if the power is elevated. This car came with stock hardware and a mild tune and the owner asked to achieve the full potential from the stock GT2256v turbo. So we mounted an intercoolerkit, build a completely new "straight through" exhaust system in 70mm stainless steel and did a software tuning. The result: a real sleeper with stock appearance, but with a rubber burning 500 Nm /240 hp engine under the hood. Kick the accelerator pedal down, the turbo spins up immediately and a beautiful 5 cyl roar is produced. Loads of driving fun garanteed! ... See MoreSee Less

It is quite amazing how much overcapacity the Giulia 2.2 JTD engine has. This is a 180 hp eco version with auto transmission. Completely stock engine, only with a DPF/Catback exhaust line in 76mm. 3300 mbar of absolute boost pressure from a 52mm compressor is about as far as we dared to go... With EGT's maxed out to >900 degrees, new hardware mods are needed to push further above 260 hp. So a bigger turbocharger and water/methanol injection will be added. ... See MoreSee Less
