I'm considering installing cams on my Z this summer. the power band on my z start to fall in higher RPM so, what cams would u recommend to go with?

what am looking for 7000rpm(+ if possible ) as my red line and a cam to hold my power up-top as much as possible

note i have small IHI turbos which have hard time breath up top. ( PE-TT )

which of these cams would be best for my set up :

GTM stage 3
BC stage 2 or 3
JWT


also, i don't have any head work

thanks for your input guys in advance

 

damn 500+rwhp aint enough...



you wanna fly!!!!!

 

JWT C8 if your really serious about top end power. I love mine

 

C8 must be loud as hell.. my cams are loud and they are the JWT C2..

BTW i didnt know they made C8.. checked jwt and nothing...

 

your cams hold the power to or past 7K rpm ! can u post your dyno sheet if u have one please

 

My cams sound badass and JT@ PF made power to 7k with no problems. JT has my dyno sheets (I'm not much for posting dyno results) and I know he is swamped with customer cars now, so it might be awhile before he posts anything on my car.

 

whats the lift on these cams 288/272

 

+1 for the C8s

 

couldn't found them in JWT web any other place for reference and spec

Anything with an "R" at the end just means its for a revup engine.

 

so, the C8 with PE kit is the best choice so far for top end ... am saying that because i know Greddy turbos are way bigger than mine so will they work as good with the PE kit

 

thanks

 

272

 

Your not going to make more power on the top end since your turbos are already becoming maxed out. If anything, you should swap in larger GT28's

 

The C8's aren't easy to come by...You may want to consult with Jim Wolf first to make sure it will work with your build. They're pretty aggressive

 

The cams will still help top end even if the turbos are maxed out. Your power will just not be as good if the turbos were more in their efficiency range.

 

The PE's max out at 500...I did not know that

 

am not really looking to have more HP or TQ although am sure i gain some. what am looking for here is to hold my power level until 6800/7200 if possible. cause after 5K/5500 my HP/TQ start to fall

 

The C8s were designed to work up to 8500rpms (from what JWT tells me). The cams are agressive yes, but nothing to agressive for these turbos since the owner wants more top end power. The cams do not need any clearanceing of the head, unlike the more aggresive C9.

 

Not true. I would elaborate but Im driving
