Default Stock location vs rotated???

Hey, guys I have researched every little thing I need to do for a build, so I am not a total n00b. I just can't find info on this. But I am now debating whether or not to go rotated or stock location. It seems to be the only thing I am stumped on.

First off besides the price and parts what's the real difference? Does rotated offer that much more power?

I would like to go stock location as I want to keep my TurboXS 4" DP as I believe spool times would be faster and the turbo would be louder out of the exhaust. I get to save money. And I don't want it to look super flashy because I went rotated and it looks different. Tucked away would be nice...LOL.

If they made a rotated kit with a 4" DP and if rotated is that much better I might just bite the bullet.

Thanks for the feedback guys, I look forward to your responses.

i know you have more options for a larger hot side on the turbo and larger maf pipe for topend power,what powerband are you looking for??

Hmm, I did read that the only real change is the air intake side of things is different on a rotated setup. But that obvious too.

As far as power band I would like something with good bottom end and stronger mid range. I do not want a highway monster as I don't have my STi wing anymore, so not high speeds as I won't have the proper downforce.

Does that makes sense? I hope so. My goal is something like a 3067R with 425WHP on pump gas with a hood amount of TQ. Around 400 or more. I figure 3076R as I can have pretty fast spool, especially with that DP and a different UP if I feel like it, even though the stock STi UP is catless.

Those are what I am really looking for, and what do you mean hot side? Does that make a huge difference?

Dude, the stock location turbos have always been compromises to the rotated setups. Rotated just gives you so many more options.

Okay, well thanks for the information. If spool and power gain are that different in a rotated setup, then I'll just go rotated I suppose. Just going to see what my cash money situation looks like when I do the build.

Funny that I didn't find that in the search, oh well. Thank you very much for that! Now I can make my decision.

Follow this.. I have a SL 3076R right now and its okay. But just paying that few extra hundred for a rotated and always being able to change your turbo with ease is WELL worth it. Im going to be posting my 3076r up for sale pretty soon so I can buy a rotated one.

Yeah I am only looking for 425WHP, so a rotated kit almost isn't worth it. But it then again comes down to the money. If I have a lot left over, then rotated it is, 3076R .82.

But that is probably months away, so we'll see. Then I'd just have to chose which one. Treadstone seems like they know what they're doing, so that is nice.

If you are looking for 425 on pump, rotated will definitely make it easier to obtain.

I suppose it will indeed. Now I will look up the different companies to see who makes the best one.

What kind of car is this? What is your engine set up? Transmission set up?

a 3076 will not make 425 wheel on pump gas alone on a regular dyno. You will need 25+ psi to attain that number.

Either way, you will need a built engine to run that much power. If its a wrx, you will also need a new transmission.

yeah the new xtr doms are putting down great numbers for being stock location, just so you know a turbo that can put down 400 hp is not going to have great lowend. its a give and take. but the new xtr line of turbos spool up great.

Yeah thats true also. The low end is not going to be there.

If I can sell my STi TMIC, injectors, turbo and whatever else I don't need in this build for the difference from buying a rotated kit vs. stock location I'll do it.

What car is this going into? Do you have the engine and transmission to support this power? If not, factor that into price as well.

The only thing keeping me from going rotated is the state of California. Other states are adopting our rules. If this is an issue for the OP then stay stock location. Otherwise go all out (even for a 3076) and get a rotated setup with external wastegate. Working on a rotated setup is so much less of a hassle. Opening your hood for a cop is so much less of a gamble with stock location.

I am most likely going to go rotated now, but once again I will see.

As far as my mods go for this build I will do all new internals, no head work, full fuel system upgrade, clutch, FMIC and little pieces. I have all the bases covered, no worries. This motor will be good for 700 flywheel HP, which is good enough for ~500WHP?, so I am well within my limit of 450WHP max as far as I understand.

EDIT:

I live in Manitoba, I don't think there is a huge deal with rotated or not here. I will look into it though and that will be my deciding factor because cops here in Winnipeg have really stomped on all of us cruisers for Sunday night cruise night. I'll ask around...

Yup. and make sure you upgrade your axles too or else you'll just keep snapping them.

Meh, too much money. I just want a fun DD. And cams = bottom end boo-erns, or so I have heard.

And axles, far too much money. No such thing as cheap axles out there. Plus do I need axles if I am not going to launch? Torque from shifting snaps axles? Wow if so...

Fill me in if you can.

Thanks guys, and now I sound like a n00b...LOL.

30r rotated or stock just doesnt produce enough lbs/min to make a true 400 WHP. hasn't been done and not possible even if you give it 30 psi.

race gas is a different story.

a cop can't give you a ticket because you have a rotated setup.. they don't even know what the hell a rotated setup is. now they will give you a ticket for having EWG (loudness) and exhaust (loudness).

I've had great success with a built motor-Axis Stg. II, with CP forged pistons, 850DWs, APS rail, walboro,
and an FP Green, FMIC, non-rotated, @ 360WHP/350TQ.
0-60 is 3.9-4.1, 180 top end, no sweat. Great highway TQ, great off the line response, my next will be a twin-scroll Green or Red.
Bleh on the 30R, too many lags, IMO.
Good luck with the build!


XXX
In a DD, 350TQ with the Green's very little lag, is WAY beyond enough to merge into traffic while drinking coffee, at 115.
