what are ppl's experiences with ZZps turbo cams? I just went turbo...Garrett gt3076r on 20 lbs boost for now. I just came over from a TVS setup with ZZps stage 2 blower cams and still have these cams in. The turbo is big and the stage 2 blower cams dont open the motor up til about 4k rpm which doesn't help either. Your thoughts and experiences are welcome!!!

 

put the stock cams back in and talk to zzp about it i dont think that there will be much of a difference when the cams start making power but there could be a difference in how they make

 

stock cams are already gone

 

were ZZPs cams always $650!? i thought i dropped $200 something on my stage 2 blower set...

 

ha i wished they were 200 bucks

 

I just paid 600 plus for my stge 2 blower cams from zzp but have not install them yet. How you like them with the tvs? Did you ever used them with ur m62?

 

the engine exlpodes to life around 4000 rpm

 

^ yeah...what he said

 

I want either their Stage 2 or 3 turbo cams. May just do Stage 2 since I drive around town and wont be going past 7000 too much. I want to see what the difference in spool time is too!

 

I have zzps stage 2 Turbo cams power starts to come up around 3000ish rpms

 

Where does that 6262 full spool at with them? How do the cams idle?

 

Full spool is about 4500rpms. Idle is very lobey sounding but smooth. Cams are worth it should of done it years ago!

 

Wow that is a nice spool! Do these require solid lifters?

 

nope but i also have the vulcan equal length turbo mani which makes a big difference. my old baby 3076 used to have full spool by 3500rpms

 

With or Without the cams @ 3500 with the 30R? Also did you have a .63 exhaust housing?

Also the equal length usually will increase spool RPM. Larger runners and longer length pipe decreases velocity vs. a log style.

 

without the cams and yea the .63. I also had a 5857 thats spooled by like 3800 3900 without the cams

 

has anybody installed turbo cams on the m62 ???

 

why would they do that

 

i love the cams. i can't complain a bit

 

I still have stock cams on my TVS. So I can trade you for your stage 2

 

I would recommend the stg. II cams. Good idle, good power band. I would recommend the reverse split but thats just me. I run the stg. III cams and have ran the stg. II cams. Both have been reverse split. Also, to achieve the maximum gain I would recommend cam gears.

As far as the turbo manifold is concerned, you will achieve quicker spool with a log style manifold. Keeping the turbo as close to the exhaust source as possible will net you the quickest spool. Harnessing all the heat possible is going to greatly increase spool. Once the turbine is up to speed it is easy to maintain, it's just getting it there that's the hard part with larger turbo's I agree there is some tune-ability in a equal length manifold but for most peoples over all goal and reliability they work best. I still run a log manifold on my car, FWIW.

 

Bringing this back from the dead because it pertains to some research I've been doing...

Ryan on your car, how did it react to the reverse split stg3's vs stg2?
I can't make up my mind selecting cams. A couple places have mentioned reverse split, but everywhere I look, people say that reverse split is intended for applications where the exhaust proportionally outflows the intake (in the head)

As far as I've ever heard, and seen, the lsj head is the exact opposite. One of the reasons gm only ported the exh side...

Anyway, know you don't get on here much, but thought I'd ask. Was gonna just email but figured others would like the information too.

I don't think we'll be seeing much of Ryan anymore.
