I don't know for sure, but I have a feeling it won't fit the new 09 Fit. Every time I start looking at compatible parts it seems like they have reconfigured something on the new engine. It looks like a complete redesign to me.

Apparently it has a new crank as well, I think there is more to it than the head. I asked the question a while ago;

Untill now Honda has always used the same block and has changed head (I mean with 1.3 -1.5 idsi and 1.3 - 1.5 vtec). In fact I use headers exhaust 4-1 of 1.5 vtec on my 1.3 idsi and head gasket intake is the same...
The hybrid version has a 1.3 block with vtec head....
So I think that there is a common denominator!

I hope you are right; I wouldn't mind getting the REAL I-VTEC head put on... but my hopes are fading with all the new information coming out.
Here is an interesting blurb on it; it doesn't say much in the way of compatibility though.
Things that have changed related to the 09 engine:
1) New Head & VTEC system
2) Redesigned cooling for the engine (new redesigned water passages) to reduce knocking
3) New Piston Crown Design, New pattern & Coating for pistons
4) New "cracked" con-rods
5) New belt tensioner
6) New integrated exhuast manifold
7) Change from two 02 sensors to LAF (Wideband Linear air flow) & one 02 sensor
Here is an interesting blurb on it; it doesn't say much in the way of compatibility though.
The L15A 'i-VTEC' has been developed from the L15A VTEC used on the out-going 1st Gen Fit/Jazz. For the new Fit, it has been retrofitted with the full 16V 'power-VTEC' system similar to the older D15B VTEC engines. To recap, this means the L15A i-VTEC runs 16V full-time. VTEC, like that used on the previous D-series engines is now used on this L15A. When the conditions require it (note that i-VTEC now means the L15A i-VTEC switches VTEC based on more sensors than the older D15Bs), VTEC activates a 'wild' or 'high' cam-lobe and this increase the valve lift, duration and other timing parameters to allow more air-flow into the combustion chambers - and thus more power to be generated. Power output has gained 10ps, raising its max power to 120ps from the 110ps of the old L15A VTEC. Max torque has similarly gained but to a much smaller extent, increasing from 14.6kgm to 14.8 kgm and coming in at the same 4,800rpm. More significantly is its ability to rev higher, the power now peaking at a much higher 6600rpm and the redline at 6800rpm, almost hitting 7000rpm. Now we are talking ! Nevertheless, this L15A i-VTEC is still not equaling the power output of the D15B VTEC as that engine was spec'ed for 130ps and so the L15A is still 10ps in deficit. Also the redline of the D15B VTECs were over 7000rpm (almost 7300rpm) so the L15A i-VTEC while revving much higher than before, is still not yet at the level of the old D15B VTECs in terms of outright power delivery (though of course it is a much more advanced engine especially in emissions). The L15A i-VTEC is rated at a max of 19.6 (for the FF CVT) though Honda also quotes a second 'typical' value of 18.8km/l (probably for more prevailing conditions). However, this figure is actually slightly worse than that for the outgoing L15A VTEC of the 1G Fit/Jazz which was 20.0km/l so it would seem that the extra 10ps power do come with a slight penalty in fuel consumption.
1) New Head & VTEC system
2) Redesigned cooling for the engine (new redesigned water passages) to reduce knocking

it might respond better to bolt-ons though with the new head design. plus this restyled Fit will probably last longer than the 2 years that our Fits have, so there will probably be more time/demand to have parts made for this new engine.

it's not so much about that 10 additional hp, but the added potential.

I think, instead, the real improvement is just power...
As you can read:

Max torque has similarly gained but to a much smaller extent, increasing from 14.6kgm to 14.8 kgm and coming in at the same 4,800rpm.

We should see a dyno camparison to be more precise, but my first impression is that it's better working on own engine....
PS: I forgot emission test! New i-vtec seems to be at top... and maybe this is the great difference I didn't understand before!

Sugarphreak.. Just wondering if you can give a review on the intake manifold.. Some have been calling and been skeptical about the manifolds performance gains and the CEL... Since we have fixed the CEL problems... I wanted to get some people's reviews etc..
thanks..
thanks..

Leo, I have a dyno coming up on the 30th of this month; we have a totally stock fit, my Fit, a T1R Turbo Fit and also a KWSC Fit going up on the same machine on the same day. It is a mustang Dyno, but it should illustrate just how much gain the manifold can give with a few other bolt on parts.... I think you guys are going to be surprised just how close my peak HP is to the KWSC 
Just got a Royal Purple synthetic oil change this weekend in preparation for the runs.
On a side note I am also waiting on the Rev2 manifold to show up for the swap. I talked to Chris on Tuesday last week, he said it was shipping within a day or so. Hopefully it arrives in time, but I doubt the low EGR flow is going to make any major difference if it doesn't.
All in all the manifold has been great, I will do a full review writeup as soon as I have the Dyno information to back it up. Anybody who has been skeptical has pretty much been hushed after they have a look and go for a ride. It really does give the Fit a remarkable power gain.
I did run in an event just recently, it was mostly for fun and I placed 18th out of 26th... but keeping pace with some of the other cars out there wasn't easy with the Fit! One thing about the manifold is it bumps me into the FSP class, I really need a full suspension upgrade along with a few other things that you can do in this class to make my car more competitive. Even though it does bump me into another class I really need that extra power it provides for the straight sections.
Next year I will be running in at least 10 events for points towards a championship.
Pax Time Results, #7 - SASC Event7 - Invalid DateTime
Also some fun runs from a previous event; http://www.5di.ca/Event%203%20Fun%20Run%20Results.pdf
I think one of my favorite parts is lifting the hood for tech because that manifold blows them all away

^^^ Me too 
I am getting gitty about it, had the car out today playing around a bit and I have some SERIOUS extra power on tap right now. Car feels pretty laggy in the low end (keep in mind I run a CAI and not a chamber intake) but as soon as it starts to wind up I am getting some really nice power!
In case anybody is wondering here is my engine mods for the upcoming Dyno; if it doesn't add power I didn't include it. My best power mod is the WeaponR for sure, I can't stress that enough to people who are considering it or may be skeptical of it. I think a big aspect is once you commit to the tuning computer the car responds better to other mods as well.
1) WeaponR Intake Manifold
2) Greddy E-Manage Ultimate (AJR tuned)
3) Fresh Royal Purple Synthetic Oil
4) Unorthodox Lightweight Crank & Alternator Pulley Kit
5) Fujita CAI
6) T1R Header
7) T1R B-Pipe
8) T1R 50S exhuast
The Dyno is going to be interesting, we are at a higher elevation (3000ft above sea level) and also running on a mustang Dyno (which reads lower) so having the stock Fit is going to be key to see what the percentage gain is. You should be able to apply that percentage gain directly over to a sea level Fit running on a dynojet.

One more week boyz
Illusive has unfortunately dropped out of the Dyno though, we will still have a stock Fit & Turbo (MR_ET & YeeFit) though on the same machine.
I have to say though, I was out this evening briefly and the car is feeling REALLY good.
