I have a standard 97 Turbo sorely in of new turbos (Its a long and sad story)- However with Porsche prices around £3k (Yikes!) i could do with a cheaper alternative - any Ideas or does anyone have any just lying around they may wish to donate to a most worthy cause
Other option is to upgrade to GT2 TTs, but this obviously means bigger intercooler etc.
Any bright ideas PHrs???

I have the answer:

Carnewal do a 450BHP kit (Genuine porsche kit) for £3500 and it includes

2 x k24 turbos
1 x ecu
1 x oil cooler & pipes

BARGAIN!

Alternaitvely there's a 'servicable' set of k24's on ebay for £500

Do you really need new ones, what's wrong with them ?

Places like www.turbodynamics.co.uk can do a full rebuild

Hmmmmm 450BHP wonder how much it would take to get to Demonstrators (Thats his name isn't it)493BHP?? In fact maybe he has his old Turbos????

Cheers Ace, will check it out and keep you posted.

Cuneus, have looked down the refurb route but seems a bit of a rip off so far and 1 has already said that theyre too far gone - bit dubious about that one - but looking aroung £700 +VAT. Again will keep you posted.

Cheers

Bod,

I'm not entirely sure you would need a bigger intercooler with the bigger blowers.

Don't forget, you may also lose some of that terrific off the line poke as the biggies breathe in before kicking your lights out.

I've used a brace of hybrids for three years now which have been reasonably effective.

Hi Mark

Sorry to hear of your troubles.

Considering your location, AET turbos in Normanton, Near Wakefield can rebuild, upgrade, etc your turbos...they are the main official dealer for KKK turbos in the UK I believe and do lots of race turbos for different teams so know what they are doing:

www.aet-turbos.co.uk/

If you went for the same K16 turbos again you could buy the 430 kit from Carnewal (comprising ECU, and oil cooler) slap on a less restrictive exhaust and cats and you have a good set up with little lag. Or get one of the after market tuners to fiddle with your ecu to produce even more power

As Der said, the K24 450 kit that Ace Parts mentioned will give you more lag but a bigger kick later on. But if you are planning to go for bigger power in the future then the K24's would be your best bet financially now seen as your present turbos are shot.

Would you mind telling your tail of woe so we might learn something to prevent it happening to others too?

Kind Regards


Martyn.

If you go the route of sticking on the K24s à la GT2 (that's what mine has got), then you could probably creep past the 450 mark with race cats and a good remap.

As derestrictor says, the K24s spool up more slowly (my oomph arrives at 3000 rpm) which is why the fellow Kevin on the Rennsport forum has piqued so much interest with his K16/24 hybrids. These allegedly spool up much earlier (i.e. 2000 rpm) yet go on to give the big grunt of the K24s. Might be worth looking into - if you're in for big bucks anyway might as well get lots of bangs, so to speak!

Keep us informed.

Demonstrator...():

Where are your hybrids from? Tech 9? Are they more expensive than going for the Carnewal route?

Don't be ridiculous, Johnny!

Actually, I don't think you can really beat the GT2 turbos and thinking about it, if you're hooligan enough to get a serious dollop orf the line in a tt in the first place, chances are you'll be committing the wholly unnaceptable (but enormously fun) practice of mindless clutch side-steppage anyway - ergo - what's an additional 1000 rpm or so amongst friends for the bigger shove?

Talk is rife of some ceramic turbos being imported from the land of the free although last I heard, info was patchy as to their measured performance.

Somebody was trekking over to RS Tuning for this very purpose but I've not heard anything yet. These were not cheap but were generating moocho excitement in various circles.

At the end of the day, it doesn't matter what anyone says: there is simply insufficient shove from standard or hybrid units beyond 140mph. I'd love to know what a standard or modified 993GT2 (or indeed 993tt) with the biggies actually is like at these speeds.

My personal opinion is when the turbos go, it's a great excuse for upgrading.

Derestrictor... are ceramic turbos considered a good thing? The weak part of basic tuning on my skyline is the ceramic turbo... it can't take more than about 10psi. I've been told to go for steel internals.

To coin a Paxxo, "yeeees," so I heard!

Sounds like the automotive equivalent of an early 80's Metallica opening riff.

All hail the Rodheim.

I'm in the process of getting Kevin's Hybrids fitted at the moment after I had a turbo go (also getting cats, and a few other bits and pieces done).
Next task will be to get 9m to re-map it (or to find someone closer so that I don't have to trek from the South to the North). I'll report back once its done.

Stage 2 with billet backplate, wastegate porting and ceramic coated exhaust housing.
Yet to see what the results will be.
price was about £1400

Yes, the new hair dryers and remap on Rods car combined give unreal shove low down and keep on going right to the red line. The noise from the exhaust is also excellent, like putting a Christmas issue sized biscuit tin on your head and letting many children beat it with spoons.

Bod, remember if you want to go much past 450 bhp then new suspension (e.g. H&R, PSS 9, etc) will be required to keep things controlled.....things get expensive quickly!!

Hmmmm... in a bit of a quandry now

Want Big Turbos, but little Turbos cheaper.
Need Little Turbos, but would probably upgrade in future anyhow.
Want fast car but don't want lag.

Might have found a pair of cheap standards as an interim - but don't want to waste money - mind You could sell them.

DeR, if you've got hybrids what else have you done to get 493BH?

I need to figure this out properly as could end up with an Effin fast car in a straight line, which don't corner or stops as it should.

Oooh lifes tough aint it - Have a fast car or an even faster one.

Think I'll have to lokk down the lines of BIG! Can see if I can beat Jonny 'Shipman' S in a spending contest too Maybe I'll have to bury a few more of his old patients in a few more foundations to make things work out eh?

Will keep you all posted
