Lexus is 220d
The IS 220d is more powerful (130 kW / 400 Nm) for quicker acceleration and a higher top speed. But it still achieves 5.5 l/100 km and only emits 144 g/km of CO2.
Both models set new standards for refined clean diesel performance. The IS 200d is more fuel economic and the IS 220d has better acceleration.
Engine type 2231cc, four cylinders
Power/Torque 175bhp @ 3600rpm / 295 lb ft @ 2000rpm
Transmission Six-speed manual
Fuel/CO2 44.8mpg (combined cycle) / 168g/km
Performance 0-62mph: 8.9 sec / Top speed: 134mph
Price About £22,400
Verdict A good effort spoilt by an unsuitable engine
Rating 3/5
I bought this car in november 2011. It's not powerful enough for me. I also have a 2007 VW Passat 2.0TFSI+intake+exhaust+remmaping=255HP. and the lexus has only 175...it's so damn slow.
Decided to see what performance upgrades can be done. and guess what? NONE) there's little information on the internet, no experience of dealing with diesel lexuses in my country.
So I started by replacing the stock exhaust.

here's a photo made when i changed oil in the rear diff. you can clearly see the stock exhaust.




as you can see, on the right side a new hole appeared! it's for the second muffler

second step was getting a K&N HighFlow Air Filter

to install it, had to remove the plastic engine cover


there was plenty of sand in the airbox so i had to clean it all.

stock air filter

stock vs K&N

washed the engine cover

clean like new


yesterday, I had the cats removed

overall, the car is now faster. i can't say that it's a rocket, but the improvement is evident.
next week i'm planing to install a tuning-box because you can't do a normal remmaping.

There is a good way to tune the engine and thats by installing a unichip.
I already went to the distributor of Europe and he told me I could expect something like
220+ hp.
My brother's mr spyder got an increase of 43bhp with intake header exhaust and the unichip, dyno proven.
Suspension is almost the same as the IS250. I have BC coilovers for the IS250 and the fit fine.

The downside of this box is that it's plug and play, so they don't put it on the dyno and finetune it for your specific car. In that case the Unichip is much better.
do you have a link to the thread in the Dutch Forum?
Those already exist for the ISx50 (MAPECU3, HKS FCON, etc). They're expensive, and without adding a supercharger of little benefit (about 10 hp).
But the car we're discussing isn't an ISx50... it's a turbo diesel. completely different engine, and it wouldn't surprise me at all if a piggyback could provide reasonable gains.

A diesel engine doesn't operate anything like a gasoline engine.
There's no throttle plate, no spark plugs, vastly higher compression ratios... it's a totally different thing from a gasoline motor in many ways.

There was a belgian member who got the same piggyback but from the belgian distributor and they did put it on the dyno and he got an increase of 30bhp.
But still I think that the unichip would be better because they can finetune it to your specific car.
And there are lots more functions to mess with.

I got an exhaust from an IS250 so it doesnt look diesel
