Is250 Performance Upgrades

Hey folks I would like to know what work anyone has done to their IS250 to up the power and acceleration and what impact was made.

I watched this video yesterday and it really got me thinking.

Cheers

Prolex UK do manifolds which can crank up power for the IS250 to almost 240bhp when coupled with a full performance exhaust system which i find very impressive for a non Turbo car. then again IS250 runs a very high compression ratio of 12:0 1 so has the capability of extracting more energy from air/fuel ratio so their claim might be possible. you can contact them for a before and after evidence of an IS250 making this power after manifold and exhaust fitted and if they have proof of this you can then make a decision of if its worth the ££'s.

this is another mode which could make your throttle responsive when compared to factoring throttle settings. wont give any more power though

alternatively get a GS450h which has a 3.5 V6 makes over 300bhp and returns the same mpg if not better than an IS250 V6. :)

Cheers for the info. I'm avoiding the GS450h as I'm a bit sceptical of hybrid plus I love the styling of the IS compared to the GS.

Another thing is I prefer a manual to an automatic so I think a CVT gearbox is a step too far.
