Anyone gone with the Tomei camshafts in their Z's instead of the Nismo units?? HP Gains??

 

They say that they should add between 20-25 hp at the wheels by just dropping them in. Not sure if anyone on this board has gotten them installed yet, but I'm ordering a set this week. I was told with the Supercharger, I should see about 35hp gain at the wheels with this. I duno, sounds good, hope it's true.

 

Ravaz, I've said it before, this is the last time I'm going to say it, but you need to check on the overlap of those cams. Any decent independent custom engine shop should be able to look at the specs on that cam and tell you whether it will be good for Forced Induction.

If you don't heed my warning now you could be flushing your money down the toilet. Ok, I'm done preaching now and I swear it's the last time I'll mention it.

 

Relax man, we are looking into all of this. Stop thinking we are jumping into this like a bunch of idiots. We aren't going to put stuff in here that isn't compatible. The shop says it's fine, and another shop is double checking.

 

I would wait until Crane comes out with their cams in the early part of next year. They are supposedly going to have several stages from mild to race. They are only going to cost in the $700 - $800 range according to them.

 

good enough.

 

SGP racing has them on sale for $1150 for the set. Apparently they say you do not need the spring upgrade for the valves. If you want the extra insurance against valve float they run $350 for a set of heavy duties.

 

The local racer here has put the mild Tomei cams and got about 8rwkw.

Don't expect a huge gain for the dollars spent.

I must admit it idles perfectly, you wouldn't even know it wasn't stock.

What cam set did you order btw?

 

NISMO
262/10.8

Tomei
264/10.2


Hmnnnn

which one.

both can be had for around 1100-1200

 

Correct me if I'm wrong but I think the NISMO cams are 10.2mm lift also... Tomei has the longer duration cams.. 264, 268...

I would wait until JUN, JWT come out.. compare them all....
JWT always comes out with the wild set of cams...

R

 

Tomei,s cams are 256 /10.2 264/10.2 268/10.5
none of the cams are 10.8mm lift.
All of the Jap tuners & vendors including Nismo Japan are selling the Tomei cams.
Jun & HKS may have cams in development but to the best of my knowlage they have not been realeased yet.
ARM make the cams for the Jap racing Z but they are way to wild for street use Inlet 304deg EX 290deg with 13.5mm lift. Needs special heads & pistons.
The 256 tomei needs no ECU adjustment .

 

yup, n/a cams are NOT good for FI.

 

All the "specs" are great, but without knowing the scale these figures were acheived on, theyr eally are useless......

 

No matter what you get, don't forget to contact me for all the gaskets your installer will need!!

 

yeah the 10.8 i posted is wrong. i got the number from courtesy nissan's site.
