How much is a turbo kit for my xyz - Ford, Citroen. Etc?
|
The days of off the shelf turbokits are long gone, these days there are so many different types of cars it is not possible to just offer a kit, we recommend that you shop around and see if you can get a tuner to make a bespoke kit, be warned these can often reach the £4500.00 + mark. Apart from the main turbo kit parts such as the turbocharger, exhaust manifold, intercooler, hoses, oil/water pipes etc. it is generally the case that main engine components will need to be changed to make the whole thing work and to keep reliability. These are things like, pistons, camshafts, con rods etc. Also consider, with the extra power and torque produced (30-50% increase from what it was), will the brakes, clutch, transmission be up to the new job? The simple answer is, it is cheaper to buy a car that is already turbocharged! If you are still keen on the idea, it is possible but be clear on what you are expecting and allow a good budget. We can put you in touch with some of our dealers who have done conversions before.

I want a hybrid for my car, what will I have to do to the engine?
|
We recommend that the engine be in sound condition…there is no point fitting a hybrid turbo to an engine that’s done 120,000 miles or that is in need of an overhaul, if you do fit a hybrid remember that the engine management/fuelling will definitely need adjusting and checking.

I'm having my engine rebuilt with racing cams and a fully ported race cylinder head what sort of hybrid do I need?
|
We recommend that before your engine is rebuilt/modified that you consult the turbocharger supplier before commencing, we find that a lot of tuners are still in the mode of bigger is better…we find that the best results are found mild head/camshafts and precise tolerances.

I have a GT Series Garrett Ball Bearing Turbocharger - I have been told I need an oil restrictor, is this true?
|
Oil supply to the turbocharger to be engine oil which has been filtered by a full flow filter of 20 micron maximum rating. Recomended minimum I.D. of oil supply line is 9.53mm. Oil pressure pressure at oil inlet to be 2.11 KG/SQ cm (30 PSI) minimum at peak torque speed and above and no lowerthan 0.70 KG/SQ cm (9.95 PSI) at low idle.

I want a hybrid that will give 500bhp with no lag, why can't I have a turbo that will do that?
|
This sounds great on paper but in reality it's not possible, there is always a trade off when talking in these sorts of outputs, we can supply units that give great torque and response but they will not give huge horsepower, we advise that you decide what you actually want before purchasing a turbo.

I want to fit the latest technology VNT turbocharger to my xyz and get 400bhp?
|
The Garrett VNT turbochargers are designed for diesels only and don't have the correct materials for petrol applications at this point in time.

How come I can buy my Garrett Gt series turbo cheaper in America?
|
There are pricing differences all over the world and some instances turbo's are cheaper in the US, but bear in mind warranty issues and after sales service when you go down that route…if you have a problem the cheap initial purchase may end up being a costly mistake.

I bought my Garret GT turbo in America, it's now got a fault/leaking you are a Garrett dealer so you should honour the warranty?
|
We will always try and help with a advice on Garrett products but we are not obliged to cover the warranty, bear this in mind before you purchase the turbocharger as the US distributors will ask you to send the unit back for inspection.

I have just fitted your new turbocharger and it is leaking worse than the old one?
|
This is a very common problem where the turbocharger is often incorrectly blamed as the original fault, always ask yourself - why did the turbo fail/develop a fault in the first place and check this before fitting a new unit.

I have just fitted your turbo and I can't hold the boost I want to run?
|
The first thing you will need to check is what pressure actuator is fitted, many people ask for a .5 bar actuator and then try to run 2.0 bar, as a rule of thumb if you want to run 2.0 bar you will need at least a 1.0 bar actuator with a very good boost controller (not just a bleed valve), however, quite often even the size of exhaust you have fitted will effect this, low pressure/big bore exhausts have a dramatic effect on boost control.

What pressure actuator do I need to run 20 psi of boost?
|
This all depend on what sort of boost control you have fitted, if you have no controller you will need a 20 psi actuator.
|

|
|
If I fit a 20 psi actuator can I run 14 psi on low boost settings?
|
The low boost setting you require will be the base setting for the actuator required - IE:Low boost = 14psi - the actuator will need to 14psi

My turbo makes a noise like a siren/dry bearing squeal, the turbo must be at fault?
|
Generally this sort of noise is related to an air leak, this can be on the boost side of the turbocharger, surprisingly it is more often an exhaust manifold leak.

I just fitted your turbo and it makes the same noise as the old one?
|
If you fit the new turbo and you have the same noise, it would make sense that the turbo was incorrectly diagnosed in the first instance…check for leaks as in question 12.

I just received my turbo and there is to much play in the shaft, the shaft appears to be moving more than the old one?
|
All turbochargers require some degree of "play" on the shaft, quite often we have turbochargers returned by the customer for this reason, the new turbocharger will feel and move more freely than the old unit as there is no carbon/oil sludge etc in the new unit. The movement on some turbochargers can be as much as 0.023" or more than 1/2mm of movement, it is much less on ball bearing units but still can be as much as 0.012", so if in doubt ask the question regarding this tolerance.

My actuator has an adjusting rod on the end, can I adjust it for more boost pressure?
|
No, the rod end adjustment is for setting actuator pre-load only, this is normally 2-3mm, adjusting this further will give more boost but at the expense of rod travel and actuator operation, quite often leading to turbo failures due to over speed which is caused by incorrect actuator travel.

I have fitted your new hybrid turbo together with a new 3 inch exhaust and I cant stop the boost pressure rising?
|
This is called "boost creep" quite often when fitting a new hybrid turbocharger and /or a new big bore exhaust system it has a detrimental effect on the balance of back pressure between the turbo and exhaust system, this in turn stops the wastegate from functioning as the gas pressure takes the easiest exit and bypasses the valve.

I have just fitted your turbo and as soon as I started the car the turbocharger failed?
|
Again this is a diagnostic problem, we would suggest that the fault that caused the first turbocharger to fail has not been diagnosed and this same fault has damaged the new unit, many times it can be as simple not priming the new unit or a blocked oil feed pipe. We have comprehensive fitting instructions included in every turbocharger which should be read fully before fitting a replacement unit.

I have been told that I need a GT3582R turbocharger by my friend, I want to run 280 bhp on my 1.6 Escort?
|
The first thing to do before you purchase a turbo is to decide exactly what you want from the vehicle, forums are a good source of information, however, they can be very misleading and confusing, our advice is not to get into the bigger is better mentality and ask the experts who will try to advise you on the best possible unit for your application.

Do I have to tune/remap my car after I fit a hybrid turbo?
|
Yes, the hybrid turbo will flow a lot more air than the standard unit and potentially destroy the turbo and the engine.
