So I’m interested in going stage 2 with turbo upgrade for 400-500whp. I’m fairly new to the platform and my understanding is I’ll need intake,dp,fmic,hpfp,turbo. Not sure if I should do pure turbo stage 2 or CTS boss kit based off the GTX3582R. There’s lots of stuff about the pure turbo but requires a core exchange unlike the CTS turbo.

take a look at the pure500. no core

read the thread below this one too

This one?

[mg711]

So if I go with the pure500 would that be able to make the 4-500whp range? If so what would I need- intake,cp,ip,fmic,dp,hpfp?
Also what about Vargas gc? They claim 500-700hp(on gc+)

You dont need an intake. You need CP, IC, DP bare minimum. With a turbo upgrade you also want turbo inlet, DV, and probably TIC. Then HPFP assuming you go DI for fueling.

So for say 450 I’ll need inlet and charge pipe, downpipe at minimum?

charge pipe, IC, and downpipe are required for the higher stage tunes even on stock turbo. I also recommend inlet on stock turbo, and once you upgrade turbo, inlet should automatically go along with it, or you are just leaving a massive air choke point

If you're just running something like a pure500 you might be able to use stock DV at those power levels if yours is in good working order, but labor wise it would make sense to replace it at the same time

Then you decide what fuel you are going to run and what fuel system upgrade you want to do - e.g., hpfp

I’m not sure what turbo i want to use yet because im not sure what the best option would be. Is a stage 1 pure turbo enough for under 500whp?

"under 500whp"?

450 is under 500, but so is 350.

Well my goal is 4-500whp I don’t want to go higher for cost reasons and pushing to stock motor too much since is going to be the car I drive the most.

If you have access to E85 just upgrade the HPFP and keep stock turbo and make 400-420.

That would be with upgraded turbo?

Stock turbo.

I had high hops for the boss kit from CTS but it seems to have the same issues from the mk7 platform. I had the kit on my 15 GTI and cracked the manifold within 1200 miles. makes me a tad sad because i love garrett turbos.

Dam that’s not good

What about e85? I found a couple stations to that out of the way that have it.

honestly a downpipe, intercooler, intake, hpfp and e30 with a custom tune would get you 420-440whp stock turbo... our ewg turbos are capable of 450whp according to several tuners I have spoken too

Are you not reading my posts lol...

You dont need an intake, but you do need a CP (refer to my post above). You should also get a turbo inlet, even on stock intake, especially if you are looking to max stock turbo.

450whp on stock turbo isnt really realistic. 420 is achievable but beyond that is truly pushing the stock turbo far out of its efficiency range and if you can make it on an optimistic dyno its not really sustainable or something you will consistently experience on the street.

As i said above if you want to go max HP/$, get IC, CP, DP, turbo inlet, HPFP, and just run the stage 2+ BM3 E30 or flex fuel map with E50 fuel in the tank. No custom tune needed.

Yea I did forget cp, just noticed that. I already have all of the above and waiting for my hpfp install to get my custom tune done. I was told intake or drop in filter

You really wont gain much going custom tune over BM3 stage 2+ map unless you are going beyond about E50 and then the gains are marginal. But let us know if your results are different.

And you should get a turbo inlet, even if you already have CTS intake. FYI i did test CTS (all testing done with an inlet, see my thread and the link to inlet thread in there). https://f30.bimmerpost.com/forums/sh....php?t=1765289

I probably should have mentioned i also have a stage 4 snow meth kit, and getting ready to pull the trigger on an N55+ from shuenk before the custom tune lol. I just clumped the hpfp/tune/flex fuel kit into 1 since im ordering it all from xph soonish. Just had to throew 5k at my motorcycle i didnt plan on and put me a bit behind
