chaps, anyone know much about these? performance etc. 1987 vintage, I fancy something retro!

POST 2Original post

Dont know much about them, mines a 965, but this is just lovely http://911virgin.com/930ujb.htm

POST 3Original post

I've got one and it always makes me smile. They are 300hp, 0-60, 5 sec,lots of lag then the world goes mad. They take a bit of getting used to handling wise, but when it all comes together you can't stop smiling.

POST 4Original post

4 speed...long gears....I didn't buy one as I changed down to 2nd in the wet....scared my young self at the time Would prefer late '88 in fact '89 model with the 5 speed box. Totally iconic 911 for me,,,but sadly drive didn't live up to the dream.....try before you buy,,,,not totally trying to put you off,,,,best of luck

POST 5Original post

Forgot to say, they were all 4 speed up until the last 1038 made in 88-89 when they got the g50 5 speed box.

POST 6 / ORIGINAL POSTEROriginal post

cool thanks guys. I'm looking for a 2nd car to replace the XKR which I just sold. I tried a 3.2 SSE but (much as I love them) it just felt a little too pedestrian after the XKR & the RS4 & 6 I'm used to.

POST 8Original post

Later model 3.3 as in Turbo2 from 1991...has the go and tuning potential....or 993 C2 cab should be somewhere on your radar......hang on what about that 911 speedster, with summer coming??

POST 9Original post

craigw said: any other suggestions gratefully received by the way. Another vote for the turbo II, very refined and easy to live with, but drive it hard and oh my word ! I actually really enjoyed the 964 C4 I had as well bit livlier than the turbo under normal driving (but no bloody big turbo to kick you in the butt either) If you dont want retro the 996 is a veritable bargin

POST 10Original post

craigw said: chaps, anyone know much about these? performance etc. 1987 vintage, I fancy something retro! I've been running one for a few years, so I know a bit about them I guess. Mine is a 1988 4speed. The 4 speed is faster than the 5 speed so I think it is a little lighter. Gears: 4 speeds is enough, the powerband kicks in fully at 3000 and the rev limiter cuts in at around 7000. 1st is like regular cars 2nds, so treat it exactly as 2nd except you also pull away in it. Fourth is like most fifths, at 3000rpm you are already well above the national limit, remember this thing has a top speed only a little shy of 170mph. Check baulking into 1st and synchro into 3rd - these are the known weak points. Change gear deliberately and softly - do not force or snap. Give the gearbox TIME, not pressure. If you match the revs well the time can be quite short, it's a very precise satifying mechanical 'slot' for each gear. When clicking into the next gear you put the throttle down AS you put the clutch back up. You don't drag the clutch (EVER), it is more of a timing thing as the turbo needs spooling up for the next gear. The clutch is very progressive. You WILL KNOW if you scorch it: unless you have no nose. There is no synchro on reverse: allow for the (lay?) shaft still spinning and if you can't get it in declutch for another go. It's an aquired skill thing. As is the whole car I guess.. Even after years of driving one, when you get 2nd to 3rd and 3rd to 4th right you still say 'shit this thing is fast' as you giggle uncontrollably. Pads and rotors are fairly cheap. Derived from the 917 Le Mans racer (faster but lighter). They even have quick release pads The (4 pot IIRC) calipers I suspect are not cheap! Injection is Bosch CIS K-Jetronic. All covered by the intercooler. Make sure it starts without problems at cold, half warm (after standing for 5 mins) and when warm (after 10 mins). Make sure the warmup drives without issue. CIS injection components are VERY expensive. It is also very economical and reliable, bred IIRC from racing systems. Expect to feel uneven roads through the wheel. You'll hear the diff/gears but they should not be loud. Heating and cooling is a mystery that I explained in a earlier post. Check the heating works well, it involves a number of systems to be working too. Check it also switches off. Paint should be good. Avoid rusty cars. Turbo lag. Its big. Realllllyyy big. Always give yourself time at junctions to pull out, you have no power at low revs and if you wang it out with the clutch you may have a 300bhp wheelspin, which also gets you nowhere.. As for lifting off around corners, you can actually lisft off the throttle, providing the engine power does not decrease - i.e. on 2nd at 2.5k rpm power will be building, nudge off the throttle a little to slow the build rate. Pull your foot off the throttle completely and all boost and power instantly dies: hello hedge. If you want it to feel like a Ferrari 360, keep the engine above 3000rpm and it turns into a scalded cat, very agile, responsive, fast, instant power. Dashboard switchgear is amusingly places to add character. With the heated seats and aircooled heating it is ironically the ideal winter car. Except for the fat tyres etc. Tyres are cheap - only 16" but look the business. To look after it properly you really need to budget a bargain barge worth of money every year at a good indy. Some years the barges are more highly specced then others. HTH They are amazing cars.

I tried a 3.2 SSE but (much as I love them) it just felt a little too pedestrian after the XKR & the RS4 & 6 I'm used to. Try a 928 GTS or a 928GT. Lovely 5 litre / 5.4 V8 engine, the GT (330hp) comes with a 5 speed close ratio box and will murder everything from a 996 C2 downwards. The GTS is available with a 5 speed or a very good 4 speed auto and also offers devastating performance. If you're coming from an XKR you will enjoy the refinement and long-legged cruising ability of the 928. Not to mention the V8 soundtrack. Best of all (unlike 911s) £12k will buy you an absolute minter. Check out www.928.org.uk they have plenty for sale at the moment. Joel

POST 12 / ORIGINAL POSTEROriginal post

brilliant, very very useful thank you. Will it live outside happily ?

POST 13Original post

Personaly i'd go for: Late 89 model Avoid 4 speed Try to find one with the turbo (K27) and intercooler replaced with the 965 versions. Avoid cars with claims of more than 360bhp (i.e. chav mods) They are only a few that really have more. Makesure it has original wheels. Black/white/Red. People want silly money for 930's so get your beating stick out (I have spare nails if needed). No need to spend more than 20k for a top condition car. If you're feeling flash spend twice as much and get an SE or LE. Basically same car 10bhp more with or without flatnose. Worth 20k more, not in my book.

POST 14 / ORIGINAL POSTEROriginal post

thanks UV, I'll keep looking, i think if I was spending more I'd do an odd thing & get a speedster, purely because I just love them

POST 15Original post

Early 80's 3.3 turbo, 4 speed. Lovely. That said have a friend with an 89 Turbo Cab who wants to sell. Very low miles, dark blue with matching leather and hood. Very nice car. Original unmarked Fuchs, looks lovely. If I had the garage space!!

POST 16 / ORIGINAL POSTEROriginal post

any idea what he is going to ask for it?

POST 17Original post

craigw said: brilliant, very very useful thank you. Will it live outside happily ? No real reason why not, but you do not want to encourage rust, so damp places are a no no (my garage has a dehumidifier for mine. Heat exchangers are fairly expensive too. Make sure the fresh air intake (back/centre of bonnet) is properly attached to the drain hose. You can test by tipping some water down and/or pulling up boot carpet. It is actually a car that likes regular use, and you will master it much much better and quicker the more often you use it. PS. Air conditioning never actually works on old 911s, so don't fail any on that. You need to change the 20ft of freon permeable hose to new barrier hose and then start of the other components, I'm not sure how many have had that done. PPS. The interior changed in 1986, with much bigger vents. Edited by Globulator on Thursday 1st March 17:22

POST 23Original post

rubystone said: ...ended up tiptoeing around in 3rd off boost after the 2nd gear-on-boost-in-the-wet-moment. The lag is the same in both variants The key is learning what the power is doing, and it really does not take very long as the effect is very repeatable. Above 3000 rpm you have no real lag so it's like driving a n/a car, just a very powerful rear wheel drive one. Fishtails are stopped merely by letting go the throttle and simultaneously pushing the clutch in. If you play about in the 2k - 3k band you have variable power and lag, so it's like you are connected to the power via a big rubber throttle cable, easy to accomodate over time. They key to enjoying the 930 is to drive it often enough, it is very special with oodles of character to learn, and you need familiarity. It's not like jumping into a modern boxster where a lot of the work is done for you, it demands concentration, mechanical sympathy, empathy with the power delivery and boost etc. There is a reason the boost gauge is in the tacho: it is information you need

POST 24Original post

There is no other driving experience like a 930 or a 965, had both and personally not keen i prefer normally aspirated Porkers, i think you really have to be on top of things in terms of driver skill to get the best out of these single turbo beasts otherwise you'll not like, very twitchy throttle response low power band which is on and off simple as that.

When I first drove mine (5 speed with a one bar boost spring) after getting straight out of my 3.2, I thought it was some sort of wild thing that I'd never tame, but at the same time I was instantly addicted to the rush of acceleration and the brutal and raw way in which it was delivered. The more I've driven it, the more I've come to understand it. I'd never go as far as to say I've tamed it, but I have developed a level of trust that means I can now enjoy a spirited drive without breaking out in a cold sweat. I absolutely love the car but I can however, totally understand those people that don't see any appeal in a car where so much planning is required to make sure the engine delivers what you want, when you want it. You really need to drive one and make up your own mind.

POST 26Original post

ED965 said: very twitchy throttle response low power band which is on and off simple as that. I'm not sure you can have loads of lag and a twitchy response?! My power band has a flat torque from 3,000 to about 7,000rpm, which is quite usable. It allows you to more than double your speed in each gear, i.e. 45 to 105 in the blink of an eye The main thing is that driving below 3000 rpm is a cruisish low power, low pickup, i.e. 70mph in 4th is IIRC 2500 rpm, so you change to 3rd quite often, switching up and down through 3000rpm is going to give you variable power, but keeping it above 3000rpm gives very flat power, it's just the car turns into a raging tiger and the handling really starts to kick in as the smooth GT suddenly turns in to a firebreathing monster sportscar. It is almost like having 3 cars in 1, and to keep above 3000rpm it becomes a very 'racy' sounding and handling beast, meaning that you have to hustle it but it really does respond;- putting down the 430nm of torque through the fat rubber at the back is (for the 3.3 model anyway) not particularly hairy as long as the car is balanced and the back is able to hunker down to exploit the grip.

Understand what you're saying Graham, i just found my 965 really jerky on the throttle when on boost, difficult to explain, if you backed off on boost it was liking hitting a brick wall, the same if you hit the rev limiter too, it used to catch you out sometimes. Apart from this the cars were good just prefer the normal aspirated for normal driving, feel more relaxed. Ed

POST 28Original post

ED965 said: i just found my 965 really jerky on the throttle when on boost, difficult to explain, if you backed off on boost it was liking hitting a brick wall, Thats interesting - sound like the 965 has a different turbo characteristic to the 930, as I expect Porsche were working on reducing lag, plus I think there is more power. In 2nd round a corner with boost building in the 930 just de-squeezing the throttle lowers the boost a bit and the power smoothly stops building. I'll have to give a 965 a try one day - maybe not round a corner though ED965 said: the same if you hit the rev limiter too, it used to catch you out sometimes. Yes that's a pretty brutal thing - a 'oh are we there already?' signal that cannot be missed ED965 said: ..the normal aspirated for normal driving, feel more relaxed. Agreed, the turbo does require a particular committment to driving it, it doesn't do averagingly fast very well, it's much happier pottering about or being a racing car;- a little schizoid
