Well fellas it is close to time for me to make some announcements here. We will be offering an entire port and polished head package with the option of our titanium valve springs and retainers and/or standard bore or 1mm over-bore chrome or black nitrided valves. The 1st production head is nearly ready for the flow bench and dyno testing, stay tuned as the car running is it is 1 BAR of boost or more. These packages will require your OE head with just valves, valve springs and retainers as a core.

Stay tuned for flow bench results and dyno results.

As a footnote:

Our D17 SOHC Civic head picked up 73cfm on the flow bench. Dyno baseline was 170whp on 5 PSI before our head. Peak HP was close to redline, and peak TQ was around 5.5K.

After the addition of our head, the car was put onto the dyno and made the same peak power at 4K RPMS and we ran out of fuel on delivery. We made peak HP around 4K and the car was only making 3-3.5 PSI. So in a nutshell, the same overall power on less boost and a lot lower RPMS. We have a new fuel system on the car and will be back on the dyno this week Thursday.

 

Ahhhh man, this is gonna be SICK!!!

 

nice!!.. will this head be optional for the NA guys also??

 

No, strictly FI use only.


There was a footnote added with respect to another PnP we did.

 

*sigh* oh wells.

 

impatitently will be waiting for some numbers!no pressure! good luck!

 

how is the stock 2azfe casting? I know toyota designed the fe heads as narrow valve angle with small ports and chambers to build more intake charge velocity. Are you planning on raising the rev limit to build power? i didnt think the chamber was shaped well for a higher redline. or just increase the airflow at the stock curve and utilize the stock cams? like on the d17 you did.
I cant see raising the revs would be effecient given the head profile. If im wrong please right me.



p.s. whats with the black nitrited valves? never herd of that.

 

About Black Nitride:
This is a hardening treatment that even though it is not widely used as the chrome coating, it has several benefits and is becoming very popular, mainly for European and Japanese applications.
The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum).
Surface finish is smoother than with chromed stems, having less friction between stem and guide.
Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper seats).
Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.
The nitrided layer is adhered to the base material at a microscopic level, so does not "flake" or brake when the valves bend due to impacts with the pistons.

 

have you guys looked into cryo-treatment? i hear thats getting pretty popular too

watching :]

 

Will be watching. Whats going to be the pricing?

 

 

So what car is doing that testing =)

 

The DEZOD tC.

 

oooo ok w00t

 

Titanium valve springs huh...? Interesting...

 

The tC revs so much quicker with the Head P&P

 

Dezod does it again. Be interesting to see how competitive the pricing and power gains are.

Good work.

 

If only I could print money.....

 

I know. Tell me bout it.

Downside: Inflation will occur.

 

Paul, could you offer a completely overhauled long block with everything assembled and ready to boost crazy? Just though I'd ask.
