[s-cars] My butt momentarily in a BMW

[QSHIPQ at aol.com]

Sounds so simple Cody
The reason most folks leave them 930 stock, is because that 60k engine  
rebuild comes up a lot quicker when you start playing with the mods.  I've  watched 
two bud's 930's take two different approaches over the last 5  years.  Lister 
Dave H bought his 79, left it stock (A/C delete), and we  both have had a lot 
of fun with it on the street and at the track.  So far  it hasn't needed 
much, but dropping the motor to do the clutch made a quattro  seem simple.  Then 
while the motor is out, might as well address the  assorted oil hemmorages, 
then the valve adj, and that pesky exhaust  leak....  
 
The other (former S car guy too), is a fully caged 87 930, that I  personally 
removed the porsche club race stickers off of so he could drive it on  the 
street, and at track events.  Not all that many miles on the  as-purchased 450hp 
motor, but it's on it's 3rd rebuild, now with full race  internals.  It's a 
hoot, but I'd want some deep pockets when starting down  the 930 mod road.  A 
bump to 1bar is ok, but actually I suggested a better  mod to a stock car would 
be a boost controller getting to the stock boost.   That k27 is laggy, and 
the k29 is brutally so.  To tame that LTO inherent  to Lucifer, a rebuild of the 
suspension is highly recommended.  Again, I'm  watching that happen in a 
garage 10 miles from me.  
 
It's not easy to pick the compromises in tweeking one IMO.  And  certainly 
thinking of the reality to the pocketbook in getting the right mods  working 
together to make a *better* machine, you have exaggerated reality quite  a bit 
kind sir.
 
I see Nissan quietly building themselves quite a nice chassis and  driveline. 
 After driving both the 350 and the G37, I understand the car  and it's 
market completely.  I also suspect the development on that 350  chassis is far from 
over.  All they need to do is look at what a set of  turbos did to the silky 
I6 from BMW, and Paulie's view could change....
 
I like them both as they are, for what they are.  I can never see a  930 as a 
daily driver.  I could easily see a G37 as one though....
 
Cheers

Exaggerated? How so?

The 1.0bar wastegate spring is $75  +S&H, 300hp in the bag. It's certainly a 
less-then-10-minute job as long  as you start on a cold engine - acess is 
directly behind the drivers side rear  tire, no fender liner, no jack needed, just 
8 10mm nuts to undo. It's a  dyno-proven 25hp gain, slightly more on a well 
tuned and sorted car.  Automotion, PowerHaus, Protomotive, and a few others 
sell a 400hp kit that  consists of headers, cat delete, muffler, boost knob, and 
K&N air filter.  The PowerHaus 430+hp kit includes a new intercooler. 500hp inv
olves a k29  turbo and a rework of the fuel system (usually EFI 3.2l Carrera 
intake  manifold + EFI system), plus some other things but NOTHING internal 
required,  not even a cam change (though not a bad idea). To best 550hp it's 
time for new  cams, cylinders, pistons, and heads. You *can* get 550hp on stock  
pistons/cylinders, but you have to turn the boost up to risky levels. Between  
my father and myself we've built no less then 20 500+hp 930's, and a few 
north  of 700hp - yes, dyno proven. 

You are absolutely right about the fact  that we aren't comparing like 
objects. <sarcasm on> See a Nissan (yes, a  G35 is a Nissan in my book) is for those 
that talk about how fast thier car  is. A Porsche is for those that know WHAT 
a fast car is. </sarcasm>  Sorry, couldn't help myself. I do seriously agree 
with you that it's two  different crowds. Also true Paulie isn't there yet, 
but for less then the  monthly payment on a new G35/G37 he could be on his way.
