If someone can figure out the wiring nightmare to swap in a JZ series engine and make it work properly that would be nice..lol

I would say get a intake maybe from Injen, PPE headers with no cats, a axle back exhaust that you like and get the Tune so that you can get the most out of those mods. I think that would be your best choice.

PPE headers as in the F-Sport intake manifold? What could be reached without the supercharger?

bbaugher47

PPE headers : as in the exhaust manifolds. You can get them with catalytic converters or without. I’m not sure how picky they are with emissions in the Netherlands. Catless Headers are probably the greatest power adder to our platform. With headers , tune , and a high flowing exhaust you can expect gains of 40 HP +/-

As long as we pass the Co2 measurments every year we'e good. We often do this by restricting the fuel flow.

Thanks for the information. I just got an IS 250 yesterday and I'm looking for give the engine a bit more breathing space. So forgive my ignorance. First of all, isn't PPE a plastic? Or does it refer to something else? Is there a tested and proven exhaust manifold design available? Also, as for the RR tune, can it be put on the stock ECU or does the ECU have to be altered/replaced with another ECU? If replaced, will I be able to keep all luxuries?

The ecu is altered. PPE is the name of the company that makes the headers( exhaust manifolds). Search the rrracing web site for more info pertaining to their offerings.

You don't lose anything with the RR Racing Tune. Plug in, flash, and go.

Interesting. I will definitely be PM'ing you in the near future. Do you ship internationally?
