Garrett GT22 - GT2259 - 52 TRIM - 280 HP



The Garrett GT2259 is the biggest of the GT22 turbos. Powerlevels of 280 HP can be seen with this turbo. This also means that the GT2259 will give you more power (about 10 HP more) than the smallest Garrett GT25R turbo GT2554R that can push power levels of 270 HP. The Garrett GT2259 also works well down to 160 HP. The GT2259 can use all the GT22 turbine housings. So there are different options for you. Recommended engine size for this GT22 turbo is 1700cc - 2500cc.

I also have more technical pages for you that will come in handy. They will be of great help when looking at compressor maps Use the conversion tools And you will be able to calculate airflow, pressure and HP figures for the turbocharger you are interested in.

Folks don't forget about racing safety gear when buying auto racing parts

I have been tuning engines for a long time and with that experience I tend to look a bit more at how other people tune their cars and bikes than anyone else. Now this is not true for everyone, but most of you will recognize yourself at some level.

About 25 years ago the level of tuning an ordinary street car would ever see was at most 30% increase in power. (Not true for every car out there, but I'm talking ordinary street cars here)

So if you had an Ford, Volvo or BMW the amount of power you could get would have been in the 150hp range and in some extreme cases 250hp. At this point this was the "limit" of ordinary naturally aspirated engines at that time. Yes there was a lot of racing going on at that time, and some of these race engines did get put into street cars and power levels would have been 300+ hp. But the amount of maintenance these race engines required and the cost to keep them running were too much for most people.

Back then you could not just go into a racing store and buy yourself a set of forged pistons and connecting rods. Let alone camshafts and valves to build your race engine.

With the introduction of turbochargers however the power suddenly increased to levels that are still uncommon in today’s cars. At the beginning people where not really sure how to tune turbo engines and intercoolers where something that most people had never heard of. Silicone hoses where did you get that? And real drag tires where not that common either.

But as time passed by, engine tuners got their hands on more parts and knowledge and the tuning business took of.

Now it still took some time before engine management systems where you could really start to extract power out of engines became common. And if you found someone who could tune these you would have to fork out serious doe to get everything working.

Along came chip tuning and turbo engines. What was unheard of just 20 years ago would now become a reality for anyone with a few minutes of tuning. Some of you might know the story of the Ford RS Cosworth, Nissan Skyline, Audi S1 Quattro, Lancia S4 to name a few and other icons of the late 1980 and early 1990. The turbo engines back then would give you 200hp and that is still today 25 years on about the same power level you would get from a new car. However today this is a common power figure for a station wagon. And back in the 80s only a few racing breed turbo engines would give you that.

But with a few changes to the ECU with chip tuning and some larger fuel injectors all that was needed then was to turn up the boost pressure and 350hp where unleashed. The only real limit here was only how much air the standard turbocharger could supply.

Sure there where different levels of basic tuning you could do but the effect was the same, more power.

With more and more tuner friendly cars coming out over the years the power figures are still holding almost the same. But what have changed today is the huge amount of DIY tuners out there. What engine tuners did 25 years ago have now entered the garage and racing parts have now become widely available to anyone. From the cheap Chinese made turbo exhaust manifolds to wastegates and almost every tuning part you can think of to the pure racing parts like forged pistons and engine management systems on sale that anyone can buy.

So what has happened is anyone with a little background in mechanics can now build their own race engine. Power levels have just gone up and up and up.. It’s not uncommon to see street cars today with 500hp and then there are the ones who have gone even higher, breaking the 1000hp barrier.

The one thing that all these engines have in common to achieve such power levels are of course the turbocharger. Without the turbo it would not have been possible. Well I’m sure a supercharger could do the job too but that’s another story.

However time and time again people forget the most important parts when tuning cars. I’m talking about safety and racing safety gear. I do see that people buy racing seats and that’s good. But most of the time they don’t buy racing seats because of the added safety. It’s because they think racing seats look good. And what about things like auto racing helmets that keeps your head intact. Most of the time people come to the track without real racing helmets and if it’s street racing that’s taking place, no one seems to bother wearing any kind of racing helmets at all.

I do understand that people feel protected inside their car and they don’t think they need roll cages and in some cases opt for roll bars instead but you really need to think about this.

Some of the racing safety gear you should look at are the following:
racing suit
racing shoes
racing helmets
racing gloves

In case you don’t have a fuel cell in your car and there is a chance of fire or fuel leak then you should consider racing fire suits also because these will save your life. Fire is not to be taken lightly. If you have a good fuel system in place to feed your engine and anyone who are looking for power is going to have that. Then you need to understand that at any given time those racing fuel pumps are pumping 2 gallons of fuel every minute. And if you get a leak and have an accident you are in real trouble if the power to the pumps are not cut right away.

So having the right racing safety gear to protect you is always a good choice. Today’s car are much safer than the ones years ago, but you need to understand that when we double and triple the amount of power and turn our 100mph car into a 200mph fire spitting monster of a car you really, really should spend some time and pick out some racing safety gear also.
