hi Todd,

- volt gauge = to check if your charging system works as it should. I had a broken regulator before and fried a couple of components without knowing (charging at 18V instead of 14V).
- afr gauge (air/fuel ratio monitor): this is to protect my full engine rebuild investment. After spending 15K, i don't want to damage the engine by running too lean or something else. After i installed it, it was immediately obvious that my CIS was running like crap...hence the swap to EFI.
cheers, Jan

Thanks wreckah and Trackrash.

Trackrash - do you have a name or link or something where you found that gauge?

For my 82 SC I’m looking for a sportier, more aggressive exhaust. I have a stock setup besides the test pipe. My mechanic recommended M&K. What do you guys think?

Rennshift + Wevo Coupler
SSIs w/ 2 in 1 out sport muffler of your choosing (ideal for street)
16x7/8 Wheels and 205/225 good tires
Momo Prototipo w/ eccentric spacer
All maintenance/wear items

These changes have made the biggest difference to my SC.

Base line performance.

States pressure cast light alloy rims. I thought Fuchs were forged?

They are but for SC's, but Cookies were standard and later for 3.2 C's Phone Dials, both are cast wheels

It'll go faster with an SC 930-10 after you lighten it...mucho.

Did vanos ever state his goals?

Changes that I have made that I would definitely recommend:

1) 7&8 x 16 Fuchs
2) Karsten spring
3) 930S steering wheel
4) H4 Headlights
5) a/c delete

I would also recommend the following--original owner already did these prior:

- exhaust (B&B tri-flow headers and 2 in / 2 out exhaust
- strut brace
- F/R sway bars

The early SC’s tested quite a bit faster, check out the Car & Driver 1978 911SC targa road test, that car would run with a 3.2 Carrera! 0 to 60 in 5.5 sec if I recall correctly, I think primarily due to a higher flow fuel distributor and large port heads.

I plan on “backdating” my ‘82 SC to an early CIS set-up with matching large port heads (among other mods). My Stock ‘82 “dies” around 5500 rpm and it drives me nuts, if I want big block torque I’ll drive one of my pushrod V8 cars…

964 cams will take care of that.

I wouldn't put too much faith in that piece of literature. It also says the engine layout is "Air-cooled, four-cylinder, horizontally opposed" :rolleyes:

I agree with all of this. The SSI and exhaust made the biggest difference for me. I'd add continually looking for ways to remove weight and replacing worn-out comfort seats with something more appropriate to the list as well.

Old thread but relevant info...I've lightened m '83 SC to 2300 and have a Euro 930-10 with SSI's etc....10.45 lbs per HP. That moves pretty nicely.
I found some cloth Recaro's w/ headrest that are very light...put some Pascha on the center sections so looks good too. They wear well also...have had them for some years now.

For me, there's no better cheap and easy mod for an SC than plugging the decel valve. Having the engine drop RPMs slowly is not cool lol.

Prior owner of my 82 Targa

Plenty of power to redline

Ported intakes and runners to 36mm
Replated Nikasil's w/ JE Pistons - effective static CR 9.7:1
Elgin SC330 cams timed at 2.0mm
SSI's with Dansk Sport 2/1

How so...'better' is a relative term.... the mods I've done have made mine 'better'...now, if you are talking about owning for a short period and selling...a flipper...then you are correct.

I think location should govern your mods somewhat.

I tried a few of the tricks for SCs incl. 2021 cams, SSIs and CR CDI box. Definitely made a difference but it’s not the “silver bullet” power wise. Most of what I have around me in close proximity are freeway on ramps. For that, I think an SC is inherently undergunned and the exhilaration of a turbo would be A-plus.

I took ~150lbs of weight out, refreshed the suspension (and increased TBs), added 9x16s to rear and drove to California. The exhilaration of flowing through corners and being able to use all pro forma 200hp all of the time was priceless. That’s the hook for me. That I could comfortably and reliably cruise all the way back home fills me with admiration for CIS (I’m ashamed to say).

I’m going to try and continue to take more and more weight out on the sly, without changing the cars appearance as a stock car. If my ship comes in, I may think engines or a stable mate but it’s getting pretty good as is.

No, it says 4 cycle engine, not four cylinder. That is the official Porsche spec sheet. They are always conservative of HP and performance figures. Unlike many manufacturers of the time that would flat out lie about HP or torque.
