Owners of 300 hp Row "S" cars

Hi,
Looking for other early "s" vehicle owners that would not mind being "go too" for questions about the car.

Like part differences from a 4.5 of same year.

Please ping me if ok.

Thanks you!!
Rick

Several models all a bit different. First 928 were 4.5L Kjet cis injection, US and Euro were same except for cats in US. US switch to Ljet electronic injection in 1980, Euro ended in 1982 all were rated about 220 crank hp. In 1980 Porsche added the Euro S 4.7L with upgraded compression, heads, and intake upped the power to 300 crank hp and added front and rear spoilers. Non S Euro ended in 1982, 1983 were all S but still 300 hp cis, 1984 to 1986 Euro S got LHjet (MAF) and 310 hp with the 86 getting the full suspension and brake upgrades of the 1987 S4.

Ask away, several owners of various models are here.

Ditto. Except to add that many of the early ROW Euros imported to the US were 4.5l, though clad with S bodywork. From what I've read, the S designation didn't actually occur in Europe until after 1982, so stuff like spoilers and changes in head design were considered normal year-year improvements to the basic vehicle, added with little fanfare.

I have a 79 with a 84-86 Euro S motor using 83 Euro CIS injection.. I used to know what I was talking about years ago when I did it, we'll see what I remember

Visually the front and rear spoilers are the only difference without opening the hood. In driving both cars feel about the same up to 3500 rpm where the S takes off and non S is soon running out of air and dropping off. None are very fast 0-20 mph, but once going the S really scoots with the wide power band exactly fitting the gear ratios in the transmission. Like the later GT the Euro S feels like it wants to go fast.

This mostly applies to the 5 spd manual, the AT version of the Euro S is much faster than the non S if you push it hard, but the AT takes a lot of fun out of it. The later models with 4 cams and torque boosting intake design make much better choices for AT drivers.

Has anyone tried that intake on the early engines? Was there any appreciable increase in torque? I ask, because it seems there have been a few for sale (usually attached to engines) around my area lately.

Intake does nothing for torque, maybe even a bit less due to lower velocity in the larger cross section runners, help a bit on higher rpm HP, but HCI, heads, cams, and intake need to work together for max benefits.

I've bought every Euro S top end part that I've found at a good price, they are the key parts to a higher performance engine.

the cams are a large portion of the "euro" gains over the US car.
bigger intake mani and valves certainly helps at high RPM though.

I have looked for euro parts, head and intake with no luck. where have you been able to find? Also is the 5 spd the same as the regular trans? I just replaced mine with an 87 but want to replace the syncros and keep the old one as a spare.

while i am at it i have been told all row "s" machines have lsd - true?
Thanks!

LSD varies in Euro just as much as US models, transmissions have the same split between early ZF and 85+ Borg syncros, Euro S often has more aggressive gear ratios (higher rpm at cruise). The Euro auto trans has a MUCH higher stall on the torque converter, like 2400 vs 1800 rpm, more scoot, lower mpg.

Rotten people like myself buy all the Euro S parts that turn up at good prices and hoard them, but cars get wrecked or timing belt fails and parts do come up for sale routinely. Euro S heads, cams, and intakes have been selling for decades, due to cost/gain and expense of shipping them vs complete motor.

The Euro S is not magic, its not even the best option, ALL of the 4 valve motors make better HP and torque, its the usual balance between money, performance, and deviation from factory original (While not original, the Euro S looks mostly original and was the best factory option at the time).

I have to say I like the look of the early cars the best. Personal preference... they look more hand-built, or something.

The more stuff that got slapped on them, the more I'm reminded of the decade that each was built in -and not in a good way. I do like the aero mirrors though.

Maybe the biggest issue for most, which body style do you like, same goes for changes in the interior. The 928 is already such a love/hate car maybe it should be no surprise that most of us have firm preferences in model years, interior and exterior colors etc.

Fortunately its used to look, but the short answer is everywhere and frequently. I would do nationwide searches of craigslist with every spelling of Porsche I could think of combined with 928 and 928s. Once I found a source I would keep in contact if they had any chance of finding more stuff.

Also many sellers have no idea what they have or are willing to sell, so its good to talk with everybody.

Its also good to help both sellers and buyers if you can, putting people together on deals you don't take advantage of yourself.

All total I've bought and sold about 8 engines, and turned down about twice that number for various reasons. Finding parts is easy, make a fair offer here or on Rennlist and you will get several responses. The hard part is finding good parts at great prices, where you trade time looking for money saved.

Thanks for the information on searching, wonder why it didn't occur to me before . Next big question, and I think I know the answer....

the S Rows should have double exhaust correct? I think mine has a regular 928 exhaust, it meets out of the headers and into 1 not especially large pipe.

Next question, is there a good aftermarket exhaust setup?

Thank You!

RoW "S" have double exhaust all the way.

If we are talking about a aftermarket exhaust for a RoW "S" then the Borla single exhaust is too small

The killer exhaust system is from Greg Brown, scary torque and power, equal price. I would very much like to have one, but I also would really like to see if I can get a Tri Y set of headers made just the way I want (SoCal has dozen of shops that make custom headers).

Single or dual isn't the issue, its cross section and how well the X or Y merge is done.

Most don't go with headers for various reasons, common is to use the manifolds from the US 85/86 which flow well, and bolt up with a couple inches of offset that must be compensated for with a spacer.

I have an 84 S Euro ROW project that I just got the other day. I have a new post about it on this forum. There is a lot of good information about the Euro cars here. My computer doesn't like RL for some reason, but I know there is a lot of good info there as well. Is there a Euro only photo thread here? That would be cool.
