Hi. I plan on going down the turbo route later this year, and I have been doing endless amounts of research in regards to which turbo kit to go for. That I am pretty much set on; full race.

Now I am trying to figure out what turbo size to go for. The kit offers the EFR 6258,6578 and 7163. I have a sound understanding on how turbos work and smaller turbo equals less lag, but I am trying to get a deeper understanding to properly figure out what turbo is best suited to my needs and goals for my future build. After being put off by just the sight of compressor maps and the calculations, I decided to dive in the deep end and try to gain some sense.

What are my goals? To make a balanced fun weekend/track car. It will definitely spend most of its time on the streets with the occasional track day, with the aim to eventually go to track days once a month. I want the car to be as reliable as can be; yes i recognise it won't be as reliable as stock but I don't want to be blowing parts often. I have no fixed power goal, although I would see the car hitting around 350whp on pump gas (93 for those in the US, 98 Octane for me down under).

When I first buy the kit, it will be a straight bolt on. No upgrades to fuel pumps, clutches, engine internals. Bone stock. I would expect to be around the 270whp and 220 ft lb. Again, these are ball park numbers as I intend to upgrade the necessary components. After about a year of owning the kit and creating an 86 fund, I plan on upgrading the necessary parts to handle the extra boost and go to around 350whp and 270 ft lb. I have already worked out all the parts needed; been researching for years; originally going supercharged route but the flexibility of a turbo kit got me.

So, what I would like is for you guys to hopefully help me to gain a greater understanding of how to read compressor maps, and whether they are a great tool to allow not just me, but anyone new to turbos, to figure out what turbo is best for them. I have done hours on the internet and most forums over complicate things and use jargon and just try to prove who has the bigger ego. Those with advice, could you please try and dumb it down so everyone can get a benefit out of this.

My first stupid question is how to i get images that I have put onto photo bucket onto the forum. I would like the actual image to appear on the forum rather than just a link so everyone can easily see what we are talking about.
