NISMO Competition Heads (I'm getting em)
I'm about to purchase the NISMO Competition Heads cuz I'm tired of waiting for someone to find another solution to breaking 300whp mark N/A. Im getting it from z1auto.com but I dont know whethere to get the stage 1 or 2. Does ne1 know how big a power or drivability diff it would make? Well anyways, with that, Im hoping to get the titanium valves and the NISMO S1 Cams. I'd like to know if this is too aggressive a set up for the street/weekend autocross. Later on, if I'm not satisfied I'll have to work with the APS Plenum, Crawford Headers/Cats, etc(N/A Mods). Please help me with deciding what to put in.

As for the Nismo competition heads I would get the stage 2 since Peter P who has the stage 1 here in australia on his race car didn't get great results.

"More clarification.
The Nismo head has 1mm smaller valve seat than the stock head & the exhaust is the same size as stock.
The VK45 inlet valve is 1mm smaller than stock & fits straight in Nismo head.
This head is not being marketed as a bolt on application for road cars but as a high flow head for race engine builders & with cam blanks for the engine builder to do with what he wants.

You need headers, exhaust, intake manifold, and cams should get to 300 whp. Tha with a little tuning from a e-manage or SAFC. people like the SAFC for some reason even though it cost $200 more.

Yea I'm hearing that the heads arent really getting results, I talked to Doug through email and said he's developing heads too at Crawford. I may just wait for that. I mean 1500 bucks is a lot to blow on sumn that doenst get more than 10 whp.

we didnt install them because we didnt have access to the titanum VK45 valves etc at the time.
It is all now regularly stocked items for the head kits.
You can use stock or any other cams that work with the stock heads with these...
You can get the NISMO S1 cam kit to work with these heads but will not bealbe to use the factory ECU...

I would not be using either of these heads with merely an SAFC. A complete reflash done on the car with a combination of dyno and road tuning could be made to work, or some sort of programmable standalone.
An Emanage with the fuel and ignition harnesses should work in the right hands. No way I'd trust this sort of jump in compression to a something like an SAFC (since it only manipulates MAF signals, whereas the E Manage with the harnesses manipulates IPW and Ignition timing signals

EManage:http://z1auto.com/prodmore.asp?model...gmt&prodid=491
Deciding whether to get the stage 1 or stage 2 is highly dependant on your mods. Neither one is going to "make" more hp than another...they are rather constructed to accomodate certain modifications (ie valve choice, cam choice, piston choice)
I'm personally not doing these heads, but rather having a set of heads built up by my machinist. I'll be using the F Con to control it all

Adrian:
It seems to me that F-Con V Pro does not have the functionality of controlling our camshafts.... am I correct here? I was thinking about using F-Con V Pro before my MoTeC M600, I was just not too sure about that one... do you know anything about whether or not the F-Con can control VTCs? Thanks!
cheers mate,

to be honest I do not know yet - the F Con has all sorts of neat things it can do, but HKS USA is of little help as they themselves are really only getting their first taste of it. I'm still not even sure myself if the ecu needs to control the VTC, or if its done via mechanical means (ie oil pressure).
Given the right cam selection, you might not even need to play with cam timing at all.
Once my heads are nearing completion I'll know alot more about the setup I'll have - right now its very much out of my hands as I merely delivered a set of heads, a set of headers and a few sets of cams to my machinist with "marching orders" - telling him what I've done, what my hp is currently and what I wanted to net alongside ecu tuning...the rest I am leaving up to the experts
