You should be careful about the tubular manifold. The GT3076 is MUCH heavier than stock so I don't know if a tubular manifold for a stock turbo would hold out. I took it to a shop here in Japan and they said no way with their manifold.

 

The Full-Race one looks quite beefy. Also, the weight of the turbo is partially supported by the one boss on the lower side of the turbine housing, and the bracket on the compressor housing.

If paranoid, a bracket could be made to go from the manifold to some other solid place on the engine.

 

I was thinking about the extra weight but likely I'm going to settle on a Xtremeboost or the Full Race manifold. Both of those should be a sturdy design, worst cast scenario I'll have a friend weld in some extra support if it looks like it will need it. In fact the Full race manifold specifically says it was meant to bolt up to the Garrett GT30 turbochargers.

 

I noticed you also ordered a 255 pump, how are you going about mounting it? I know that UR has a "drop in" kit which hits the pocketbook for $300 (with filter). A buddy of mine locally had a machine shop build him a sleeve to make it a drop in (similar design to the UR kit). But I guess my main question is getting the stock in tank filter to go back on.

Just curious mainly...I'm very frustrated that its so hard to put a larger pump in the X...with the 8s and 9s it was a $100 pump and you were done.

 

Someone linked me this for a fuel pump install. It's likely not as sturdy as using the UR piece but I ordered the bits from the website he links as well as an in tank fuel filter and it should still do the job.

That will buy me time to get a fuel surge kit or other method to avoid fuel starvation lined up.

 

To Hiboost and others,

Unless I am missing something in your mod list, what is the reasoning behind spending the money on a tubular manifold (which last time I checked carried a pretty hefty price tag) rather than a set of cams? As I am sure you know shops appear to be making solid numbers with cams. Another thing that puzzles me about this is if the manifold produced large enough gains all shops such as (AMS, Buschur etc.) would have already produced these or so I would have thought.

Please don’t take my question/comments as a negative I am merely trying to understand the cost benefit as it relates to making the most horsepower. This is true not only in this case but with all of the parts that are available for the X. I will be the first one to admit that I don’t know much about the benefits of a tubular manifold but would certainly be open to hearing what you guys have to say.

Thanks

The tubular manifolds offer superiour flow compared to the stock cast manifold. On a stock turbo, you'll see improved spool/response and greater midrange with a slight gain in peak. The limited peak gains is mostly likely due to the stock cams and small turbine housing. Once you go to the bigger turbine housings of the Garrett turbos, the stock manifold becomes one of the main choke points.

As for why to do the manifold before cams? Well, it's one of those 'while you're in there'. To install the turbo, you have to take off the manifold, downpipe, etc. So it makes perfect sense to change the manifold at the same time.

Say you were to do cams now and the manifold later. When it came time to install the manifold, you'd be doing half (if not most) of the same install as the turbo. From a time standpoint, you're repeating about 4-6 hours worth of work, if not more. If you're paying someone else for that labor, that could be $400+.

So, might as well do the manifold at the same time and save on the time/labor.

All of that makes great sense. It amazes me how sometimes some of the simplest concepts/ideas get lost while thinking about how best to spend your time and your money.

Thanks for the informative response

Someone install and dyno the freaking thing for crying out loud!

 

Thanks for answering spdracerut, couldn't have said it better.

For me it's definitely "do it once right" and while 20-25 whp from the tubular manifold might not be as much gains as cams it's still a strong upgrade. Gruppe-S had some headers starting at $450 shipped which was VERY cost effective even if it may have produced a little less HP than more expensive ones. Sadly they are out of stock so most others are in the $800-$900 range with limited or delayed availability. The Full Race one is $1109 and somewhat pricey but it looks like a quality piece.

Cams are a solid upgrade as well but they aren't exactly easy to install on these cars and I have zero prior experience on the 4B11. That means I would be buying the stage 1 cams and getting them installed which would put them $1200+ range. Granted the HP gains are quite good but they also change the way the car idles so for a daily driver it's not an upgrade for everyone.

Likely I'm going to see where I'm at for HP after the Turbo plus supporting mods and look at the cams and/or intake manifold as the next upgrade item. Something tells me low 11's will be good enough for now but as we all know the speed bug bites you hard.

 

I just talked to my friend who stopped by a local shop that tuned a 3071. The car was stock except for a drop-in and got 330hp vs 230hp stock. Not bad IMO, but I wish I could've seen the dyno data. I'd like to know how this thing spools and what the power curve looks like.

 

I was reading through the link and this seems like an absolute no brainer. I know that the foam is intended to be submerged in fuel...but I'm just really wondering about the longterm durability...is it an ABS plastic hybrid of some sort?

 

I've talked to the same shop. From what I recall, they were having issues with maintaining 25psi of boost; they needed a stronger actuator.

So even with the 3071, there's more power to be had even on their near stock setup.

 

For all of the buzz that's been around the Garrett turbos...and given that it's been out for almost a month now...it's absolutely crazy that no one has installed/tuned it yet.

Mine will be going on the dyno on May 22nd...so I'll post as soon as I can.

 

only 1 more week!! better bring a laptop with you and update this thread the second your dyno pull is done
