New crazy build by Joel Artursson! We’ve already written about Joel Arturson’s the great Saab 9-3 Aero, when he reached the limit of 700 hp!
Is it possible to extract a total of 900 horsepower or even 1000hp from famous Saab B234R engine? The answer is not simple, The B204 and B234 are regarded by engine tuners as the preferable engine for performance tuning.
Depends on what you mean by fully tuned. Four cylinders making almost 1000 HP such as in the Pro Street Racing share very little with their stock counterparts. The engine block is the same and that’s about it.
In the new tuning session, Joel Artursson chose the another engine block, instead of B205R, now B234R – all in order to reach the first target – 850+hp.
He will try to test the limits of Trionic 7 even further with the help of Robert Uhr at Nordic Tuning Dalarna. Hopefully, he hopes to reach his goal – 900hp mark and give a good shot at the FWD standing mile world record.
Here’s what he says about his future plans: “Iam dreaming of making 1000hp with my 2002 9-3 Aero, this dream will become reality at some point in near future. Depends on time and money, stay tuned!”
