Like I said....and remember I am an owner and big fan of the E46, it is not the right platform for a very high hp turbo set up.

I have a built motor and couldeasily handle a HPF 2.5 turbo set up but the car is much more enjoyable w/ a SC.

I am planning on getting the new T trim which will up my power, but it will come on steadily, unlike a turbo.

 

FYI; I run my DRs at around 22 psi on the street.

 

I will try that for sure!

 

With turbos?

Exactly the Porsche is much easier to modify and has a larger base of guys who are willing to take it to the higher power levels. The Porsche turbo crowd has had a reputation for doing this for a long time.

That is definitely part of the problem.

 

That was my point in yesterdays "other" thread. Why build a fast car from a platform with so many shortcomings? Making power is easy, you need SO much more to use it...

 

This is just a matter of perspective. The SC will never make the power of the turbo. I would go turbo if I could as the linear powerband is not my goal.

The SC also does not have the response of the motor in NA form although the powerband is similar.

It is a fantastic platform for a high HP turbo setup. The S54 is just an incredible motor.

 

exactly ...

 

I came to this same conclusion back in 2005 which is why I left the M3 scene and moved to Porsche. For my specific purposes, it was obvious to me that the Porsche Turbo was a much better overall platform. I believe that's still true today, just as it was back then.

Only my opinion of course.

 

I would tend to agree, but I need an LSD, axles and a Tilton to agree 100%.

 

Its not perspective, its physics.

Front engine w/ no room to run anything larger than 275s vs rear engine and 315s plus.

Also the S54 has to be built to handle big power. The Metzger handles 800 rwhp all day.

Seriously, your ignorant statements are just embarrasing yourself.

 

Of course the S54 has to be built, it is 11.5:1 stock compression since it is NA. However, once built, it is an animal and can take almost anything you throw at it since it has that beefy iron block and incredible heads/valvetrain.

Even on the stock motor it can hit well over 600 whp, impressive. The 996tt rods are only good for around ~600 whp so how is that any different? It needs to be built as well.

You can run wider than 275 but to really be able to put huge hp down you definitely have to address the rear tire width in a similar manner that SCM3 or Taza here has done. That, or go with a widebody. Yes, traction becomes an issue. Happens on many platforms.

I'm sorry, but I'm embarassed an E46 M3 owner does not know more about his own platform. An HPF turbo will just flat out destroy the SC S54 M3's, period. Taza has traction issues because he is making more power than... everyone. So yes, he has problems with his 1000 whp setup but for the most part M3's are low torque and high HP so traction is not as big of a deal as most of these guys are making it out to be. Read up, please, and yes, SC vs. Turbo is a matter of PERSEPCTIVE not PHYSICS.

 

Here is one thing I will say.....which car is more FUN to drive on a road course?

IMO, it is the SMG E46, an absolute blast.

The Porsch (of course I would go w/ a smaller turbo for a road course) will have a faster lap time, but is not as enjoyable.

 

Where did you ever get the idea that the 996 rods will only handle 600 max?

I have been running mid 700's, and Powell dynoed 868 on a stock block.

 

made it up along with several other things

 

From this forum? Are you really advocating the stock rods are good for 868 whp and the motor is going to last for something more than peak dyno pulls?

I mean, Protomotive seems to believe that once you start getting out of that 6xx whp range you are pushing it on the stock rods. Maybe they don't know what they are talking about?

You have to build either motor if you want to get in the upper ranges so it is a moot point.
