Well gang, I promised I would follow up with my hahn manifold results. The manifold turned out to be amazing! I was able to hold VERY consistent A/f numbers. I would strongly reccomend this to anyone looking for a fuel managment solution. My car is an 2003 and I had absolutly no issues with the ECU trying to get back to 14.7. Installation was not bad at all, some minor modification to the throttle body bracket needed to be made as stated in the installation instructions from hahn. Hahn did a GREAT job with this piece.
I also have some sad news:
While we were tuning the car on the dyno, on my very last pull my turbo seals bit the dust and the turbo needed to be rebuilt or buy a new turbo. The car has sat for the last month while I've tried to get the money to bring this beast back to life. However, I've only run into more financial struggles. I must sell the car. It kills me to even think that selling the car is an option, i've thought hard about this for the last month and it has to go. I'm asking 7k which is practically giving it away but I NEED to sell ASAP. The sooner the better. I'm Sorry to those who are going to hate me for selling but if there was any other way I would keep it. If you know anyone who might be looking for a car. Please pass the word along. Thanks

I've been waiting for this review.
The last time you posted you said you were working out a few minor problems with hahn and that you would post them when you got it figured out.
Just wanted to know what they were. you can e-mail it to me if you wand mkennedy0322@yahoo.com
I have this set up, the install date has been pushed back due to work. but i just wanted to know what i was up to for the install.
How hard is it going to be to change the oil filter.
sorry for all the Q thanks for the reply in advance.
The problems I spoke of in my post a few weeks back was the turbo seals. I didnt want to speculate too early and place blame, that is why I waited. The turbo seals being blown was unrelated to the manifold install. So i'm glad I waited to post up.
The Oil filter can still be changed so no problems there. Just follow the instructions and you should be good.
If you have any questions during your install feel free to ask or give hahn a call, they have good tech support.

Hahn manifold? Are we talking about the Port Fueler System? I only ask because I have not heard about them making an intake manifold. Thanks.
yes he is talking about the PORT FUELER manifold
does the port fueler manifold add any hp byu itself? dyno proven?
LE61T PTE6262 Powered 
yes the "port fueller" manifold if you will. The manifold has 4 bungs and an extra fuel rail attached to it. The injectors are controlled by the port fueller software as seen on adam hahns sunfire. The car runs on the 4 stock injectors until it sees boost at that point the additional fuel is added from the 4 extra injectors controlled by port-fueller.
As far as added HP from just the manifold alone. That would be a question for Hahn.

Damn that is sexy. Every time I see on of those, my wallet wines and cries a little bit... Someday....
I should know this by now, does the RSM 62mm TB work with that setup??
Check out my Part Out List!! Great Prices !!

then your ecu wasn't one of the ones with no open loop operation. We already saw a dyno from one guy who had this mani and portfueler setup on an 04 and even with those monster 4 extra injectors it still got 14.7:1, until the owner had the ecu reflashed to an 02 eco calibration. Just thought i'd add that so the closed-loop-only ecu owners wouldn't get the wrong idea.
The Hahn manifold is a beautiful piece of fabrication, and compared to others in the market of similar construction and design, its a bargain for being under a grand and including a fuel rail. Sorry to hear you feel the need to give up Twisted, good luck with the sale, hopefully the normal JBO cheapasses won't try and wear you down to some ridiculous price.

hp gains on a stock motor , arent realy a concirn
its more of the intakes ability to gain more under boost and allow alot better tuning of the car , with out sacraficing the daily use , when not in boost

under a grand? last time i called hahn quoted me 1500 for the whole shabang and 1000 for just the intake mani...

The manifold itself is ~$900 itself IIRC. I'll check tomorrow and be sure though.

the manifold alone was somewhere in the $950 area the last time I saw a post about it. The whole portfueler setup would obviously be more. But when you put that up against the Full Race intake mani for DSM's and VW's that goes for $1200 or so, its not a bad deal at all considering the quality.

the bare manifold alone was 700-900. the full port fueler kit was around 1500-1600
glad to hear the great review

In theory that is probably the best way to add fuel to any boosted motor without messing with the stock PCM and injectors
x2
EIC's work great .specially when its all setup perfrect for you. and that manifold eliminates any chances of puddling

well.... we're not talking about full race or desm's or vw's are we? you get full race you get the best.... I still wouldnt compare hahn to full race. Hahn is amazing for the Jbody crowd no doubt top notch but when you move into the import scene its a whole nother war....

Full Race Intame Manifolds for the Honda B-Series Intake Manifold are only 899.00 and they are CAST intake manifolds.
Just thought I would clear that part up since its not 1200.00 dollars.
As far as who's stuff is better, I'm not one to judge or to compare since I have never used either one of them.
From the looks of things, alot of labor goes into sheet metal manifolds which are made. Mostly, alot of the cost is because of how long it takes to get them made... well also, there is profit in there as well...

I didn't actually look up prices, I was just going off of what i had heard in discussions on Vortex about Full Race's prototype 1.8T mani...
As far as hand made manifolds go, you're absolutely right karo... For kicks i tried making one out of spare steel stock at work, and it was a royal PITA. I spent probably 8 hours on it over a few weeks, and had only milled out the flange and the base of the plenum. Granted, I was using a manual mill while i'm sure hahn has CNC capability, and aluminum also cuts quicker, but its still a lot of work and a CNC doesn't pay for itself. And it goes back to one simple fact.... outside of GM, who has a tank-style manifold for as good of quality, with extra injector bungs and a fuel rail, for the ecotec? I'm no Hahn nutswinger, and you of all people know that Phil, but the manifold is damn nice, and the price is fair. I said it was a good deal, I never said it was cheap.
