TB Turbos anyone?
1) Who is interested in getting a turbo installed to their diesel? I just want to see if we can get enough interest if TB Turbos will give us a discount.
2) Who has had turbos installed by TB?
I would be interested if the price was right, I mean not at the current rates!
i would be interested at a HUGE discount
I have a TB turbo/intercooler on my 300GD 5 potter and as I've said before very happy with the results, remember the kit alone to fit yourself is £1100+vat so their all in price of £2100 for 3 days work isn't that bad.
I would love some extra go for my lwb '82,but would be very worried about the extra stress on such an old engine,even though it is in good shape.Would prefer to go the om617a route a la Bill Moss,(thanks for the pics Bill),as the engine had important internal mods to help strenghten it,but these are not common around here.
I would like to know more,especially about the possibility of getting a kit.

A Turbo from TB in Lancaster has been fitted to my 463, 6 cylinder in July 1998. The cost was £2115 incl. VAT.
The vehicle has now 145 bhp and I can only recommend TB Lancaster. The Turbo has never given me any trouble at all. Peformance on and off road is brilliant. Mpg is around 22-23, but I think I could achieve more if I would drive 70 mph on motorways instead of 85 or 90 mph.
A few issues of the GWizz back, there was a transcription of a magazine article about the turbo conversion done on a 460 300 GD by http://www.allardturbosport.co.uk/. Has anybody out there any experience with these? Do we know if they still make them and how much????
I can advocate the company and its conversions. My family has a Nissan Bluebird diesel (don't laugh, and we're not cabbies). It was turbo'd by TB in 1992ish, and given to friends in 2003.
The conversion has so far been faultless.
I've just bought a 1983 300GD LWB (five pot) and I'm definitely thinking about getting a turbo fitted - you can include me in any proposed discount deal
My 1989 300GD LWB was bought already converted. No problems to date, but i'd hate to see how the old girl would drive without it!!.
Averaging 22mpg, with mixed driving, a lot less when towing.
TB turbo was recommended to me for a conversion on my E300 W124 estate, by Mercedes themselves, so they must be doing something right1

Yesterday, Thursday 1st July 2004, I collected my 1983 LWB GD300 from TB Turbos havng paid the £2,000+ and dove up to the South Lakes area where I had to collect a caravan and return to Nottingham. At a place called Grizebeck there is an extremely long, steep hill and my GD 300 only just managed to get up it towing the van with the temerature needle creeping up into the red and the engine eventually steaming over at the top. After it had cooled down, I refilled the water system and continued home but twice on long motorway hills the temperature went up again. As a total amateur it occurs to me that the cooler for the turbo is a small radiator which is positioned in front of the main rad and this plus the weight of a two berth caravan may have been too much for the old girl.
I would have the rad recored and all the cooling system checked. If the system is still original after 21 years of service it's just a miracle that it can but cope.
Cheers,
Roly knows where to have a rad recored cheaply and professionally.... if he doesn't reply to this send him a p.m.

TB Turbos are extremely good diesel engineers with a long history of fitting turbos to just about anything, I have had many dealings with them over years.
They do a good job. and I wouldnt insult them by asking for group discounts they are too nice a bunch of people and the rates they charge are allready reasonable.
But it is pointless fitting turbos to old engines, if you want to feel the full effect of fitting turbos and intercoolers it is I would have thought common sense to do it to a fully reconditioned engined, you might even find that when every thing has become gas tight again and the injector system has been reset etc that the performance improvement is allready there, or at least back where it ought to be.
So many old 300s have the fuel screwed down to get through emission tests and never reset its a wonder they run at all.
617a engines are a good exercise, take for example that they have 2 timing chains thats twice as many as the 617 many other internal parts are of a completeley differnet spec ie pistons main bearings big end bearings gudgeon pins piston rings all are designed to take the increased stress of a turbo which in eccesance forces more air fuel mixture into the cylinder to cause a bigger bang.
All of these changes can not be done in the time it takes TB to fit a turbo, so if they do fit new crank shaft bearings, which they may, they wont have reground the crank or reprofiled the cam or rebored the cylenders and fitted new piston rings.
Now taking that more air is being pushed into the cylinders but the parts that seal the compression in are worn, that extra pressure has to go somwhere, it will go straight past the rings and pressurise the crank case and unless you increase its abulity to breath it will force its way out of the crankcase via the seals, it will reveal itself to you as oil leaks that you can't get rid of.
Next, more fule burned more heat to get rid of, plus a direct oil feed to lubricate the turbo is created it also picks up a lot of heat and returns direct to the sump it does not get cooled untill it has been round the engine again and passed through the engines oil cooler, thus your engine will always show higher temps, so recon your rads and flush out your coolers.
my moto, do it all or don't do it.

For what its worth I also found TB turbos to be top notch, very helpful and professional.
I have a 300 GD 460, I m very interested to suit it with a turbo...so you can add me in your "interested purchasing list" and aprecied receive information on the exact cost. Few days ago I contacted STT company to obtain information on their Turbo Kit they equiped a lot of Mercedes in Norway,; they informed me they stopped to sell it (only parts are available).
I am running one 300GD with a TB Turbo, 2years no problems.
Installation done here in Aussie.
My other 300GD is undergoing a heart transplant at present, will install a TB when finished, and motor is run in and settled.
So yes if you can buy kits below GBP1,000 , I'm interested.
