Which porsche 911 for the track?

[Lennard]

I want to get a 1980s porsche for a track car project, a turbo is too expensive since they seem like you really have to invest over 25k to get a nice one.

For the initial buy i'm looking at around 10,000, which is the best model to go for?

Who're the best people to supply parts for the 80's 911?

Buy a tuned rwd 964. They are relatively cheap because people usually look for originality in older cars.

SC's and 3.2's both are good, rust is the killer..
Get most of my stuff from Matt at type911

You won't find a 964 at 10k, certainly not a tuned one, and definitely not a C2. Their values are going up, whether original or not. Less well cared for 3.2's may be around. How about late 80's front engined cars, or does it have to be rear engine? Can be made very good track cars.

[Lennard]

A less cared for 3.2 sounds good, what's the difference between the SC and 3.2 in terms of the track?

Any other people who can supply motorsport parts for a 911?

Have a gander over on the impact bumpers forum , loads of info there ..
BenC over there has just done an SC track car , now under 1000kilo's

In standard from a 3.2 will be heavier but probably faster, an SC will be lighter, a bit more thirsty and of course more zingy

[Lennard]

Is the difference just the engine?

Mostly yes. If you buy a late 3.2 (87+) then the gearbox changes too - early 3.2 and SC use the same box.

Minor brake, torsion bar and ARB changes happen over the years too but thats mainly to deal with the extra weight, an early car with later ARB's, torsions and brakes make for a nice track combo.

Least rust + most desirable upgrades should be the main target and build from there. All that said outright speed on track in a 911 is more to do with the driver, you quite often see "slow" 911's showing "fast" 911's a clean pair of heels.

I'd suggest looking for a race car - a decent SC will be £10k-£15k and won't need much (if anything) doing to it to use on track. They're usually very sound too, either due to having been fully built/rebuilt for racing and then cared for (stored inside, only used on track etc) or having been modified from a very sound donor car to begin with (why would you throw £10k converting one for track use unless it was fundamentally sound?). It will always be worth roughly what it costs too and you can get using it straight away.

Just make sure you actually get a good one! Don't assume that all race cars are maintained regardless of cost. As with all things, buy on condition.

Where's the best place to look for a 911 track car apart from here?

Which years are considered 'early' spec?

Sorry I didnt mean early early - that was a bit of a red herring. I meant early in respect to your original question ie SC or 3.2.

SC was from 78-83 with small power increases over the years, 3.2 starts in about 84 using the same 915 gearbox as the SC then gets the heavier G50 gearbox in 87. Most parts are interchangeable except you cant use G50 rear torsion bars on 915 cars (and vice versa)

There is probably hundreds of hours of reading material on this on impactbumpers.com

Might give you an idea.

The Goose's old one (pre-shunt I should add!):

[OlberJ]

That's my idea of a fun car.

If you're going to strip it anyway you can weld up the holes and paint it lairy colours.

1000kgs and 230bhp is pretty decent. Always option of updating to a 3.6 engine at a later date.

[Lennard]

All sounds great! I'll do the reading over the weekend since i've got a few reports due in, thanks for the info guys... i'll let you know what I end up with!

Which gearbox does the 3.6 fit onto, and which models had the best engine as I know sometimes later models have higher compression or better features?

Both the G50 and 915 can take the 3.6 with a conversion kit , Jevvy's done a few so could tell you of costs etc , there is a current thread on impact bumpers re the costs and benefits of the change..
SC's come in 180 and 204 bhp guises , the 3.2 231 bhp.
Been on a couple of dyno days and have seen big variances in power in both models .. Have a look at Johns blog , lots of info there..
