Zex 105300 cam & AEM cam gear for a stock D16Y8?
I'm going to be pushing my bone-stock D16Y8 (sans ARP headstuds) to its limits for an event in June, and I'm trying to find some good ways to put the most "power" down. "Power" = 230-240whp, hence the quotations 
So far, here's my current traction solutions:
- ES motor mount inserts
- 205/50/15 BFG drag radials
- OBX LSD & rebuilt Y8 tranny
With regards to the motor, would a Zex cam and AEM cam gear be of any benefit to my setup? I'm going to be running a Precision SC50, ramhorn manifold, 3" open downpipe, Tial 35mm WG w/open dumptube, Uberdata-chipped P28, DSM 450's, etc. etc...
What's the highest you can rev a stock Y8 head with a Zex cam and AEM cam gear?

Re: Zex 105300 cam & AEM cam gear for a stock D16Y8? (boostincoupe)
I have a zex 59300 in my stock z6 with arp head studs and I got zex valvesprings also....I rev to about 7200 which is stock readline but I am pretty sure it would be ok up to 8000...my motor only has about 100 miles on it though so I don't get on it very much since it isn't broke in yet...I also am not yet turboed but will be

I had the same setup, but stock engine, no headstuds, stock cam etc, I used a sc50 60/63 and on 13psi i hit 264whp at 7200ish and was still making power up to 7800 and i shifted at 8000 all year, even missed gears, you shouldnt be too worried, i used 444 cc injectors and they were maxed out but i was using a conservative tune which was a bit rich, 255lph walbro and stock regulator, AEM cam gear but never adjusted it.

I was one of them, did it for over a year of very hard driving. No worries!

I'm personally getting the same cam but don't plan on using a cam gear. The Full Race Pink's Civic used the 59300 (z6 version of the 105300) and it gained about 40whp across the board over the stock cam with no mechanical timing adjustments. I just bought one today.

Call them and ask, they used a 59300 (I worked with them on it). You shoudn't use that cam with stock valve springs.The Pinks car was revved to 9,000RPM's. The power was falling off after 7500 but the high revs were needed to land in boost for the next gear.

the zex cams are designed pretty well, and made my aem cam gear purchase a waste. I lost alot of power whenever i adjusted the cam gear to anything other than stock, and i believe others reported the same thing

Are you running the 105100 or the 105300 with upgraded valvetrain?

The 105300 documentation states that it makes power from 2000-7200rpm.

power will fall no matter what cam you use.
the main bottleneck after a good cam becomes the head and intake manifold.
here is a good comparison:
My car d series, mildy ported and polished
Here is another d series, a well ported and polished head
now both cams are stage 2 zex (mine 105300, his 59300) which are the same except the 105300 is made for the y8 and the 59300 is for the z6 motors

Even with major, major, port work the SOHC will be hard pressed to make power to 9000+RPM's. Plan on making usable power to ~7500, the rest of the gear will be simply to keep the revs high into the next shift-as I said before.
