Thanks in advance.

_rocket,
You might try searching here for some of the info on RS clone builds. I'm sure the minutia was debated endlessly there.

There is a huge list and I'm sure someone will post it before I get home.

As a pair of wise philosophers once said: "harder, better*, stronger, faster" .. I think that sums up the idea behind the Porsche RS models versus their non-RS counterparts.

* Perhaps replace 'better' with 'leaner'...

Send me your email and I have the RS tech spec book (graciously shared by some other member).

Hopefully you are referring to WKD499620 'Service information Technik '96 Carrera RS' but do try to get an original, the copies I have seen are pretty poor.

also
WKD 424520 "'94 & '95 Technical Specifications"
of course the 993 shop manuals and lastly any RoW PET

Yes basically the price and the wheels as stated above and a couple other things below off the top of my head:


The engine is a M64/20 type 3.8 liter producing 300hp at 6,100rpm and 275 ft lb of torque at 5,000rpm. (standard 993
is 3.6 liter engine)

gears) gear ratios are taller in first and second than standard carrera but shorter in third through 6th gears.

locking value under deceleration 65%.

Yes, I have an electronic copy of the WKD 499 620. I may have gotten it from you, Bill - I forget.
