So if your goal is defined, why are you asking about A/R? Your goal should determine your turbo choice.

Because that turbo comes with 2 different a/r options.

I'm not sure you fully understand what A/R is...

It affects spool speed and shifts the power band in the rev range

If you don't know how the basics of how a turbo works, i would highly recommend not building your own turbo kit.

the .72 A/R will spool slower but allow for greater peak power. the .57 will spool faster and shift your power band lower.

[nickdd6237]

Think i can reach 350hp with the .57 A/r? Id be happy with that.

Isn't 350 the advised point when you should go with a built engine?

Nick, can you just buy a turbo kit for everyone's sake.

To the OP.

How much money do you think you will save i'm curious. I know you've talked about saving money to get exactly what you want and how people tell you, you wont. But i have yet to see some real numbers being thrown around.

It sounds like you want to stick under 5000$...Thats fair. But i also saw that you are trying to piece together various parts from various kits. The customization itself is going to take a toll on your budget. Think in the thousands easy. You claimed earlier that you are already 2k in with the turbo, and the manifold. You are almost halfway through with your budget and you dont even have the important parts that will allow your car to even start up much less run properly. You want E85 too? Thats already going to cost you anywhere between 600-800$ depending on who does your tune. If you dyno tune expect to spend another 250-500$. So now you are 3k in from your 5k budget. Ok so piping? Thats another 300$ if you go with a cheap ebay option. Oil cooler? Theres 600$ minimum right there. How about a boost controller? Or maybe something to gauge your boost to make sure you arent over boosting? Thats almost another 700$ right there. And this is assuming you are installing everything yourself. Oh can we mention we havent even finished building your turbo kit yet?

So now you are 5k into your 5k budget, you dont have a complete turbo kit and you've left no room to purchase the other small items you need or to pay for the custom fabrication you are going to need to get all the parts to fit.

And yet you dont want to buy a JDL V2 kit which can be custom to your specs and WITH a Flex Fuel Kit you will be out the door just under 5k. Assuming you install everything yourself.


There hasnt been anything in this thread that has convinced anyone that you know what you are doing. Hell I dont even really know what i'm doing and i still know that buying a kit is not only going to be more cost effective in the short AND long term. But i also know the kit will legitimately work.

I mean, that's entirely ignoring the fact you can buy an SBD kit for what, 3k?
