I don't know why Ben's car always drop so much power around 6.5k rpm, the shape of the curve of the older turbo looked about the same as this one. My car with ****ty BC 272 cams which are barely better than stock holds power all the way to redline.... according to the graph..
Anyways Ben's car is fast as hell and he can run more boost if he wants to. Maybe try an intake manifold first before doing cams, try the Process West one .

Look I'm not trying to be an azz but your power drops off because you don't have the cams. Do it Ben put some cams in your build! You have the bottom end, you have the heads and you have the turbo. Your missing one of the components! As an example I am making almost as much power with a 58 lb turbo and 1000cc injectors and its because I have all the components all working together in harmony. I'm weak on the injectors but I did not like the options between ID1ks and ID2ks. Soon there will be a good in between there. I have only praise for yours and NF's work on your ride and documentation!!! Thats my only criticism! (well not crazy about the injectors). LOL |

Ya, not criticizing, just curious Just knew that he's been building his car for a lot longer than me, and my build was geared around just getting the car up and running without too much trouble. I knew his plans a bit for the headwork, just curious if there was a reason outside if cost for the cams.
I'm also a bit surprised on the power dropoff after 6500...but now you're making me think bad thoughts on a new car :/ |

How are the injectors holding up? What's the IDC looking like? Also, you mentioned fuel pressure on return return side being compromised. Is that something that would likely affect fuel cut? I gotta pick your brains for all I can while I'm spending money on my own build. Lol Learn from those whom have already conquered.

I have a setup that I can build and grow into rather than one that's totally maxed out. Getting everything up to the same level is good but then it takes a huge investment, or almost starting over to get any further. This what happened with my last setup. I slowly worked to the point where just about everything was maxed out. Then I totally revamped and went to this. I hope the motor can handle the turbo (at least as far as it makes sense to push it on a Subaru platform). The fuel has a bit of headroom still. And the heads are already ported so dropping in cams basically just comes down to when I have a grand lying around. I was a bit curious to see what the stock cams would do and I think they're doing pretty well. Once I'm on summer tires I'll try to get some more logs which will be good for comparisons if/when I get cams. Either way I'm not at all unhappy or disappointed with any of my choices. I have a daily driven car that runs a full boost, E85 tune and has the versatility to swap in a variety of PTE turbos within minutes if I wanted to (both smaller and larger). All for probably less cost than your fully built stock location setup. Two different approaches that I think both get good results. Quote:

I also won't mention the cams again, I don't want to beat a dead horse here! I like your build and its ability to easily change it up. It's too bad we can't just slide the cams out the way other platforms are able to do. That would be nice if we could! I think you guys made very good choices with your build! My build is pretty balanced as I said the only thing maxed out are the injectors. I have the ability to change up SL turbos easily if I want to. I just need more injector to turn up the wick some more. My exhaust is all v-banded as is the Killer B up pipe so changes are fairly easy. We built things with flexibility in mind and all the components have far more capacity in them, definitely not pushed to the max now! Changing to a rotated set up would be a little bit of work but not out of the question and may happen in the future and I would also use a PTE turbo, V band HS but with their BB cartridge, I really like all the wheel pairing options they offer! I highly doubt you spent less than I did with our current builds. It's not evident to folks here but I re-used most of the components in this build excluding the short block, head work, cams, turbo and injectors. This is the third motor/ build variation for my XTI, two utilizing the stock block and VF and this fully built version which has exceeded my power goals by quite a bit! I actually made an over-all schematic/ plan of the builds and the evolution early in my modding of the car. It was not fully detailed of course as our build options are always evolving, thanks to the great vendors and shops like NF and HP Techs that support our platform! I feel fortunate that I have not made any big mistakes in my builds, a couple small ones but fairly easy to correct. Sorry for going off on this tangent but since you brought up the cost scenario, I felt compelled to explain my rationale! Agreed both good builds with very good results! |

manitou: I need to clarify that I'm not trying to criticise you. I just went through the same thoughts recently and giving my thought process. I had a fully bolted, stock location setup. Not the KillerB and custom stuff you have but I had Invidia header and downpipe and GrimmSpeed EWG as well as an intake and inlet. Looking at all of that and considering wedging in a Dom3/4/5 I didn't think it was worth it vs. going to a rotated setup.
I think I'm much more modular now and overall it's just a nice clean setup that's easy to work on. Both are very good options and have pluses and minuses. To me, I think 400-500WHP is the limit to where stock location makes sense. But that's just my opinion. I'm sure bigger stock location setups can work well too. |

Ben, No worries, I did not take it that way! My issues were that I had this nice custom Killer B up pipe and my trick EWG exhaust system, my ETS TMIC, the custom ram air fed Cobb air box already on my last VF build. We deliberated over going rotated with a PTE turbo and having to modify these parts or pulling them out but made the decision to see what we could do with the SL turbo's. I talked to Mike at Blouch who helped me out with the 3.5xtr so we gave er a go! I really liked the wheel pairing of the 3.5 vs a 3 or 4, kind of like your 6266 vs the 6262, a little bigger turbine for top end flow but they still spool well because you have the smaller compressor to drive from that bigger turbine wheel! A thought I had after I get the ID 1300's and push the 3.5 a little more was see if Mike wanted to make a 4.5 for me but I probably could not get a way with the top mount then. I think i will see 600 WHP once I have the 1300's and that will be plenty for me.......I think!! hahaha, that's what they all say!

I'm sure that the car needs cams, but I'm also sure that Nuke could have easily lowered timing down low so that timing slope was greater. It would give the impression that torque held for longer in the rev range.
Or it could be aggressively timed down low for drivability. I'm just pointing out that there are other variables that make the curve look that way. My point is that the curve likely looks that way because that's what was wanted. |

I should have a 50-100 and 60-130 video up once I can get my summer tires on. Hopefully soon if it keeps warming up. Break in was hard and fast. I think you'll have to ask Nuke if you want more info than that. |

I'm pretty impressed with this turbo. While I had the advantages of a TMIC, dual AVCS and a dual ball-bearing cartridge, this 6266 can keep up quite nicely. I'd love to see this 6266 with a full twin-scroll exhaust, dual AVCS and maybe even a TMIC! Could be my next turbo if I ever build an STi again, lol
You know how much timing you were running up top? |

I like the plot! I was wondering if you were going to do that. Did you only pull yours up to ~6800? I'd be curious to see how yours looked to 8k vs. the larger turbo. I think with cams and a little more boost the top end advantages of the 6266 would really show more. I also think this turbo on a TMIC would be a bit of a waste. For a TMIC I think the GTX3076 or PTE 5858 may be a better choice.

Haha, that ain't happening here. We'll see how they are here in MI. If they boot me they do! I'm sure they won't give my car much of a look though

We play it safe running the 1/8th to see where we're at. Even then coasting after the 1/8th if we're trapping 105mph the car will roll through the traps in the mid/high 11's. Those that know who see this know wassup.
