The LMS kit didn't need any modification to fit to 3GR since it's the exact same engine from outside.

Hey Jeff.Do you know the ignition range in both 3GR and 4GR?I m curious about the dyno result.Do you happen to know what supercharger did the Mark X using and how much boost did it run in order to reach 316BHP and 42NM of torque!I wonder what are the specs from my Procharger.If it s small and can't give the power I expected but then again in my 4GR I saw 60BHP!Why didn't I gain that in the 3GR?

I ve spend many hours in reading about the superchargers and I guess the Roots supercharger which Toms is using in the Mark X perhaps is more powerful at low RPMs than my Procharger.Of course I can't understand again why the 3GR makes 316BHP from 252BHP Mark X is producing and in the 2GR the same supercharger is making 360BHP from 306!
Anyway I can't understand some things and I don't want to push the car further by changing the pulley(without knowing it s safe).Mathew can't do anything else and RRracing replied that they can't help so I guess this is it.

So you can’t just buy a 350? I didn’t know that. Bummer man. Sorry your build did t go as expected. Swap in a bigger engine.

Thanks buddy.Actually the car is faster than it was before in all RPMs but I was expecting to reach supercharged Mark X 316BHP numbers.I can't understand why this happened.I guess it's the procharger but I can't understand why the LMS kit gave 60hp to the 4GR and just 40 to the 3GR.My buddy who did install the same engine without sc kit made 233BHP.He dynoed the IS250 190BHP and not 208 BHP as they say it is so perhaps dyno to dyno has some differences.He gained 43hp from the swap though.I just expected more.I wish someone could tell me that it s safe to raise some boost more!

Mathew asked me to go to an other dyno so i went to a dynopack to a Greek tuner so that he can help Mathew in tuning my car.

So the car made 256 hp to the wheels in just 0.4bar of boost.The Greek tuner told me that if i raise the boost to 0.6bar i could easily see 20-30hp more.
Unfortunatelly i have to see what i can do about the exhast because both Mathew and the tuner here believe that i should free the exchast as i can.
PPE headers is the best choice but i cant afford spending so much right now unfortunatelly!

There are other header options out there; you'll just have to find some company willing to ship overseas :

Thank you for the reply.Mathew also suggested to buy China headers.I emailed this company and said that my car is supercharged and told me that these headers are not made for a supercharged IS .

Just because a motor is now supercharged, doesn't mean the headers will now not work on the car. That's an odd statement on their part.

I know.I told them that I just want to get rid of the primary cats and free the exhaust as much as I can and they say to do it at my own risk!

^^ Agreed. WTH???
To bad they don't list any specs with these. ID of primary and collector. Wall thickness etc.

The china knockoffs are so cheap, you have nothing but labor to toss if it goes south!
