The fobiawrx stuff I've seen looks really nice! Not sure how it performs but it's a sweet piece for sure!

And per your original post, 2.5i > Cosworth. We're still gathering manifolds for a big back-to-back comparo, but our current data favors the 2.5i. With the next best oem piece being the LGT style composite.

Interesting! Is the 2.5i Intake manifold modified in anyway? (other than to me it fit) If so... then that's awesome!!! I will love to see your results. ASF Machine post about Intake manifold database shows the same thing.

What I wondered is why people don't use it more?

I don't care about the name... all I care about is performance.

BTW- I think I need a bigger throttle body or at least ported the stock one.

It bolts on I think something needs to be done with fuel rails and injectors


Can't be used with a tmic

How much horsepower are you gunning for? There are guys making huge numbers on stock TB's and slightly ported ones. And truth be told I bet the intake manifold will be a bigger restriction than anything else on that front.

I'm doing some TB research and may post about that in a separate thread or my intake-intercooler thread.

My goals are 600WHP with the FP Black ... hopefully 800WHP with the 6466.

So my FP black is fine it was something else .

600whp on the black? nice... I am stuck in low 500s right now... needs more boost and timing

You had a leak?

Yeah my goal is lofty for the 68 lb/min Turbo, but hopefully this amazing engine lets me get there. Oh and I want Roly to give it a try... to see how much I have to improve! lol

I'll give it a shot. I've seen 819WHP on an STi manifold (40 psi low 9's car)... so hopefully it works.

Yeah. But with a build like this. Go big. May as well maximize everything. We've all seen crazy numbers with stock intakes on Cobb ap's. But there is more extreme and better out there. May as well do it up!

Also I'm now drunk because I got dragged to the "In Flames" show (which was sick). So yeah.

nope it was just the cold weather...

600whp should be doable...

But did this car rev out like the longrod will? I bet it became a hinderance up top where your motor will like to hang out. For what it's worth, Legacy plastic manifolds can be found for ~$100 or so with the throttle body

I might be tempted to build a second generation prototype for some testing. Not really sure if the time spent is worth the ROI for manufacturing a stocked intake manifold (cast or hydro/rubber pad forming) in this market. I have a few tweaks and manufacturing methods that I'd do differently from the manifold on the Turn In Concepts car for another sheetmetal manifold.

You could always just do the design in cad (I'm sure you've got some sort of 3D design tools?) and have a composite manifold or metal or fabbed as a one off. Saving you the time actually building it. Dunno. I think I lost too many brain cells last night. Lol

And shoot me an email when you get a chance.

(Jesus I'm hungover. Mid week concerts are a no go anymore. Bleeeergghhh)

I'm fluent in several cad and analysis programs and use them often. However either method is going to cost several thousand and that's just that. I do have access (not permission) to an SLS, which I'd have to reinforce/rib to even test...and yes, I've been thinking about it a lot. Having discussions with foundries, I'm pretty much left to making it as a three piece cast, matching, jogging and then welding.
The other option would be similar and lose some performance in the name of cost savings. It would have hydroformed (via rubber) plenums, mandrel runners (losing tapered runners) and LOTS of time welding in a jig (or two).

Option three of testing is to make it by hand, one-off, again.

I'm sitting about 200' away from the SLS right now. Making an o-ring sealed, two piece prototype crosses my mind a LOT!

Hnnggh. Would love an sls to play with. I'm just using a crappy home brew 3D printer that a friend built for laughs. Would love to step it up to proper rapid prototyping. But I don't do enough stuff to ever come close to justify spending that much on one. Maybe the costs will keep dropping!

SLS proto plus CF reinforcements. Drooooooooool!!!

No - they work well right out of the box! You could always add some plenum to it if you wanted; that portion of it is still pretty small for a bigger HP vessel. And I'm not sure why they're not more popular. If people CFD' a stock STi vs. the 2.5i, they would be A LOT of people running them.

Got ya covered on the rail/injector situation


aaand in case you want to run a drive-by-cable throttle

Think less Chevy and more Mopar The factory TB will serve as a restriction around 600 HP.

Well said. Just because an Evo can make 800whp with a stock exhaust manifold/bolt on style turbo doesn't mean it's the best way to go about it. hehe
In flames official smiley -

We'd love to include it in our test if you do! So far we have Sti, Sti JDM spec-c, LGT, 2.5i, Cosworth, Magnus.

Well the only one prototype that I might be able to snag for a quick test would be

...and it has a Q90 throttlebody...so maybe I need to make another

No worries Micah! I was pretty busy during the weekday as well. I want to make sure I do things right with the few supporting mods that I still need to get (Standalone, IM, rotated kit). Got some great tips here. I like what I see with the Syvecs as I keep reading more and more about it.

According to what i've heard from those that know more than me; One of the guys behind the Syvecs ECU used to be at pectel (now I believe a part of cosworth).. Don't hold me to that though, I could be totally out in left field. lol.. Point being Syvecs is the good shiz.

What are you planning on doing with this ultra beast? Time attack? Mile car? Viper/lambo/super bike killer? lol - either way I am excited to watch this build!!
