Would saving up and buying a turbo kit be easier or would buying all the parts separately be easier on KA24DE? I'm not looking for huge amounts of boost i just want the basics that will get me to boost.

If you were to go with a custom turbo setup, it would save you quite a bit of money depending on the quality of parts you bought, but I believe that boost designs has a good setup for $1800, which doesn't sound bad at all. I have a couple friends putting together a custom setup right now. If you are just looking for a little bit of boost, I would buy a T3 turbo (or maybe T3/T4 if you eventually want to up the boost, but that turbo would cost more). Then, you buy your intercooler, downpipe (or even weld yourself a downpipe), wastegate, and there are a couple other little things, but the main things you would want to get first are the turbo, intercooler, intercooler piping, and downpipe I think.

OH! And definately the turbo manifold. I almost forgot.

the basic BD kit is 2k$.

Wow, they upped the price then because I looked a few months ago and I thought it was $1800. Oh well. I could be wrong I guess.

A kit would definately be cheaper. Check out turbocalculator.com, they have a variety of kits for cheaper than most any other places around. Their T3 50trim kit with internal wastegate and 30x10x3in intercooler is $1273

#1. You get what you pay for.
#2. Those kits don't come with oil lines, fuel management, BOV, etc.
#3. The turbo for that price is a fucking small ass turbo.

boost design prices went up becsaue they use to come with a T3 turbo and they would charge $200 dollars extra for the optional T3/T4. now the kit only comes with a T3/T4 so technically speaking, its the same price.

This is too vague of a question. Too many variables.
