This is a performance head package for the 1nzfe. Not sure if it would be compatible with the VVT-i, but it's worth a look.

anonymous user · 05-19-2009, 01:43 PM

$1800 huh. I'll have to read further when i get home from work, b/c all I'm seeing right now is a core exchange program of stock parts, milled or ported then re-installed.

i dont get it .. you pay about $1700 but you have to ship them back your stock ones... if so they should be selling this alot less.

mrbond · 05-19-2009, 01:46 PM

That's what I was thinking. The things that interest me the most are the cams and valve springs, since we could take our heads to almost any machining shop around where we live and get those ported and polished.

45 hp NA!?, if the price were lower i may consider it, i really doubt the 45hp though

cali yaris · 05-19-2009, 02:25 PM

I don't trust that company (from my Scion background).

1. Without dyno charts, don't believe power claims.
2. I could do head work for a lot less if anyone wants it done (and I'm sure I'm not the only one that can set up an N/A head).

I do see the reason for a core charge, as the company needs to end up with a stock head to work on for the next customer (like I'm doing with the throttle bodies.)

staticorex · 05-19-2009, 02:28 PM

I don't believes it!! :p 45whp does sound high and like ^ said no dyno=bs.

mrbond · 05-19-2009, 02:38 PM

Yeah, I've never really trusted that site, since there are no dyno charts for anything they sell. I just thought it was an interesting idea.
Garm, what sorts of places WOULD be able to do head work? I'd go to you, but that's a good 2000+ mile road trip :P

hatchbackkid82 · 05-19-2009, 02:41 PM

Would you be offering this service?

severous01 · 05-19-2009, 04:19 PM

hmmm...33% increase isnt too bad, but i've seen 50% on a good head job...heh

any way, cams have a lot to do with it, as well as programming. if you notice that when you buy a head cam package through summit or jegs or even edelbrock for v-8 cars...they will use their heads, their cam, their springs/rockers/lifters, and even go as far as using their manifolds. but all you get when you order the heads is the heads...option for assembled or not.

any way...i'm sure i could easily get 45hp out of a head job...if i replaced cams/tuning and a throttle body with the head as well.

mrbond · 05-19-2009, 04:28 PM

^ I don't think we are able to replace the intake cam, since it's controlled by the damn VVT-i. I believe the exhaust cam and larger throttle body would be the most we could do without a shit ton of work to the ecu. I wonder if we could use the Camcon in place of a new intake cam...

thats what she said.

this website makes me think they r swapping on the 2AZFE head onto a 1nz block, r they? if so the stock ecu would shit a brick if you did this. CEL's all over the place.

battleversiontc · 05-19-2009, 05:47 PM

ive actually ran there head package before they do make the close to the power advertised cause the valves are bigger ports are bigger cam lobes are bigger and the throttle body they send is better ive also ran toda head package before theres was better well this was on a 1.6l single cam honda motor did put alot more pep into it. you send your parts back they refund you the core charge so its pretty much you paying for the parts being put on the labor and the cam and the port job

DerFlosser · 05-19-2009, 09:27 PM

how big are the valve reliefs in the stock pistons? A head job alone with bigger valves and cams won't get that unless you have a throttle body able to allow it and a bottom end able to allow big enough cams to get the power (hence question about pocket reliefs on the pistons).

eric81 · 05-19-2009, 11:12 PM

Port and polish your own head, and just get the bigger throttle body from a junkyard and it sounds like it will do the same. Maybe even faster.

severous01 · 05-20-2009, 12:42 AM

there's a reason they use the smaller valves. intake any way....they're lighter, cheaper, and increase velocity of air coming in. velocity equals better mixing and better fuel economy.

now, with bigger valves, you have more force needed to keep up with the rpm demand (bigger springs), more power wasted pushing that spring and heavier valve, and you also have a problem with fitting bigger valves into the head. but on the other hand you lose velocity and increase volume. now....we all know volume of fuel plus volume of air equals power.

so an easier option would be to increase duration without increasing size. you get good velocity at low lift, and you have volume at high duration.

any way. there's a lot more to porting and cam designs than what i know...but i do know that you will get very little in just 'polishing' your existing head....and also you have no idea what the coolant chambers look like in there or how much wall thickness there is...or how much you need to keep from dumping coolant in your cylinders. i'd stick with a professional doin all that....he's probably got a good CNC program for them

cali yaris · 05-20-2009, 01:08 AM

I haven't seen a dyno on a 1.5L where cams make power yet. Maybe an artifact of VVT-I, but I know a couple people who have played with cams and it hasn't happened yet.

Someone make the call or write the email and ask for proof. That will settle some of the 'armchair quarterbacking' that always happens in these threads.
