The day has finnaly arrived, collected the 911 turbo. The second 911 and realy not sure if I like it ....

Is it
The most docile super car ? ie, you can run around town in top, its not quick if you use the turbo but just brisk.

or is it the most useless torque band ever on a car since the invention of 2 stroke cars ? How on earth do you keep them on the boil ? Am I doing some thing wrong ? are they all or nothing or do i need a hybrid turbo to cut down the lag and having to rev it so hard to get decent boost ? saying that when it hits 4000 rpm and the boost gauge hits full it pulls harder than any car ive ever been in, is that I wonder what there all about ?

I think the challenge is in mastering the art of making "good progess" without falling off the road mid corner as the boost rushes in and overwhlems the rear tyres.

Plus, when you floor it in third at 2500rpm and hold on tight, it's quite a rush right?

People just don't seem to get the point about 930s. They're absolutely horrible things, but remember the poster on your bedroom wall?

Park it up, look at it, and smile endlessly.

Don't drive the thing!!!!

Should have posted on here before buying it...and we'd have told you to find a 5 speed one - 1986 on IIRC.

If it's black, sell it to POORCARDEALER, he still has the Braun poster on his wall.

Have you driven it in the wet yet?....even more fun!

250 miles today...mostly in the wet....


so far the car is standard, looking at new sports exhaust, uprated turbo and dump valve. Main Idea is to make it more drivable rather than more HP. If I could get both even beter..any ideas on what to go for ?
pics to follow at the week end.

Looking at the poster now..........

An early 80s turbo in fairness will not feel super fast 25 years on.....BUT they are not just about speed, its about the vicious delivery, thats part of the fun, all or nothing, if it doesnt do it for you now, sell it and get say a 964 which is quicker with a more even delivery.......Dont sell it yet though, live with it for a couple of weeks, Im sure you will grow to love it......

OK, first off, how much do you have to spend, to get your car sorted?

Second, if it hasn't already, get it serviced with new filters and plugs. Then take it to a dyno. It is the only way to know exactly whats going on. It'll cost you £50-60 and without it, you're shooting in the dark.

Once you've answered the first question, I can give you some pointers.

Won't take much to overcome most of the short-comings of the 4 speed box.

Are Neil Bainbridge or Bob Watson still going...or even John Greasley...they all played with Turbos in the '80s and got some very big numbers from them...

Do you mean a 964 turbo? I can assure you a 964 normally aspirated car is considerably slower than the 930. Much easier to drive though.

Hi
I thought a 964 C2 would be a quicker car than a turbo......have driven both and I know the turbo feels faster..........

Hmmmm The earlier model turbo even in 260 hp 3 litre form is lighter than the C2 and would still be quicker in a straight line IIRC from the various test drives I had before buying a 965. Interestingly the current normally aspirated 997 car is just about a match for the 965 now I had one trying to outdrag me the other day.

That's interesting. I keep thinking my 965 is quicker the my 997s, but I think it's an emtional thought based on the terror factor. I think the 997 is ultimately a quicker machine. In my hands at least.

Just when things are going well.....

Clutch pedel started to be hard to press, then no clutch. The omega ring had come lose due to the bolt that holds the carrier coming out. Put it all back on and now the clutch cabel is around 1 inch too long and also the `helper` spring on the pedel had snaped.
orderd new cabel and spring today. Hope thats all thats wrong as I cant see how the cabel can have streched that much in such a short time unless its because the omega ring when it came adrift was stopping the cluch lever from moving by getting traped between the cluch arm and the heat exchanger and aS i was pressing the cluch pedel it was rock solid as the omega spring had jamed the lever.
Hope this dosnt turn out to be another saga like the Merak clutch...one new cluch, refaced fly wheel and a new cluch housing and a £3k bill later all seems fine...

Oh I am sure your correct that the 997 is quicker a to b. The 965 still has the edge just about in a straight line but only by a fraction unless the guy in the 997 bottled. What's this terror factor you speak of?

There's something about the way the car behaves that makes me believe it would prefer me in a coffin, and is determined to influence that possibility.

Come on lads, let's get back to the plot, we're talking man's cars here for all those equipped with a stick-on hairy chest.....


That's a lovely looking 930.

To sum up your options in getting the engine to feel relatively modern with wider torque curve and better response, these are my recommendations and approximate fitted prices (excl. VAT):

1. Headers. Junk the whole exhaust between the heads and the turbo, fit short tube, small diameter header/heat exchangers. Boosts 700rpm earlier, more torque, more power. £3000 fitted.
2. 1.0 bar boost spring. Although it also gives more power the stronger spring stops the wastegate from prematurely opening and improves the response before the torque peak. £200 fitted.
3. Turbo. Junk the standard 3LDZ and fit the ubiquetous K27/11/11. Spools 500rpm earlier, less lag, more power. £2000 fitted.

Fit the lot and I dare say you will up the power from 300bhp to 370bhp & torque from 420Nm to 530Nm, practically eliminate between gear lag and also have the bottom end feel of a n/a engine. The enggine does not need fuel modifications for this level of tune (stock system is safe up to 400bhp) but I would recommend optimising the ignition on the dyno.




As for NB, BW & JG, all I can say is "who?" Perhaps others would care to enlighten more?
