I'm thinking of going with a cam upgrade pretty soon. Which would be better for factory idle (or close to it) and quiet city driving, strong midrange and top end, and high revving ability (9k+)? Also, what would be the highest compression I should run if the highest octane available to me is 91? Thanks.

 

Do a search!

 

If you can only do 91 octane - 11-11.5 compression is probably pushing it.

The Toda Cs/Jun IIIs really only shine with high 11.5+ compression - so you would be better off with a milder cam like a Toda A or Jun II

You can put toluene in your tank to bump up octane - but that gets expensive.

If you really need to go faster - it may be cheaper to get a car with a bigger motor.

 

Since you are a beginner looking for more power, but want livability too, go for the Jun IIIs. This is from personal experience with the Toda Cs.

Run Jun IIIs for closest to stock idle. But it wont give you as strong midrange as the Toda Spec Cs.

The Toda Spec Cs will give slightly better midrange, but the idle is harsher because of the larger lower lobes.

I ran my Spec C todas with 91 octane and 13.1:1 compression daily with no probs. But I also upgraded my injectors and ran an AEM Fuel Pressure regulator. if you have any other specific questions just IM me.

Good luck!

Toda C's are nice and jun III are too, but how much $$$ are you looking to spend. you have to get more then just cams.

 

and if you do search, you'll find many many threads about jun's and toda's

 

Get Spec-B's or Skunk 2 stage 2

 

Toda B, JUN III, and SK2 II are pretty close in comparison. I am a BIG JUN fan, so I'll say get the JUN III cams and have fun. The thing you really need to think about is that high lift cams LOVE compression. I went from 11.8:1 to 11:1 and it made a big difference in overall performance of the cam. I'm now going to 13:1 with the knowledge that the cams will be crazy. Unfortunately, you can't just buy cams... there's a whole setup that goes with it... To answer your original ?... JUN cams are really close to idle with little tuning. SK2 II are also close, the Toda's are super lopey, but you can do some supertuning and get it close.

im using jun3s with stock compression 10.8 and i made 201hp and 134tq
i cant wait when i bump up my compression

 

Do you have valvetrain upgrades with your Jun IIIs? What else do you have? Upgraded fuel injectors? Do any tuning? ECU? I/H/E? Thanks

Who has the thinnest gasket you can buy? How much compression does it raise? I remember someone had gaskets that would raise .4...does anyone know who this is? Is there anything that raises it more?

get the jun stage 3.. toda cams suck compared to the juns. i ran a stock us block 10.6:1 compression and made 201whp with 138.9 tq. reved to 9,700rpms all day. eg daily driver 12.1 @ 109mph on slicks. 13.1 @ 109mph on radials!! i also had my own custom headwork, my own ecu program, sheet metal intake manifold but stock injectors and 91 octane. u dont need super high compression to run these cams. more is better ofcourse. but i did it on pretty low compression in my opinion. it worked great. the tq u get from the juns is spectacular. after 8 grand the cams really pull hard all the way past 9 thousand rpms. get them you will see. i stock them for $920 including tax. i reccomend the jun valve train or jg stiffer valve springs and titanium retainers $350<< i used them and still do in all the motors i build. juns works great too but kinda noisy at idle. thats my only beef with those.

 

 

Do they offer a single ply because their double ply only raises .3

 

cometic should do what you want... you can always use aluminum foil if need be

 

"juns works great too but kinda noisy at idle. thats my only beef with those."

Ive been running JUN IIIs with 12:1 compression and ported and polished head with DC JDM header with the Skunk2/RSR N-1 Exhaust and its not noisey at all

 

Me and my homeboys tried them all and dyno them also......jun3's are the ish.......

 

What the hell are you talking about? Note that I want compression which equals PERFORMANCE...

cometic makes gaskets pretty much to your spec, you tell em 1 ply 84mm and you got it... actually most companies should do that for you. Aluminum foil was used by the old hot rod kids, it was more a joke than anything... hence the wink at the end!

 

Kinda like an infomercial, eh?

 

what would i need to make my b16 rev up to 97k rpms? would i need a different girdle?

 

B16 doesn't have a block girdle...

 

JUN but I'm biased

 

JUN III sure does have better idle. Engine power will depend upon your setup like I/H/E/CR...etc.

 

damn dude you have traction problems

BTW Toda

97k? damn that is high maybe an electric motor or something
