B18C7 Cam choice for street / track

[VTECMACHINE]

Hey guys,

If you had a choice... which cams would you pick between:

* JUN Stage 2
* Toda B

It would be for a daily driver, that saw the track occasionally.

Why would choose the one you chose?
Would you rather build up a B16A head, or a B18C7 head?

Thanks.

Rix.

[Slaz]

They would be very similiar but i would choose the Toda over the Jun, B's and B18's just work very well, if it were a B16, id say go c's.

As for the heads, they are one in the same, just the pr3 heads fitted to b18C7's got mild hand finishing, along with the springs, LMA's and different valves, but you would want to be upgrading the spings, retainers and want type r LMA's with either cams.

Could you add other choices in there? like some US brand? Skunk2, Rocket, Blox and etc

No, sorry, it's either JUN or Toda. haha.

What rods, and valves you guys use on your built motors.

[richy]

Are you building the bottom end as well ricki?

[VTECMACHINE]

This isn't for me. lol. For a mate of mine, that asked me this question.

My engine is in good working order... so going to leave it for now.

[delsol9000rpms]

id go with the toda spec b's they are an awesome cam!.. the b16a head would be better to work on because it is cheaper and your going to work on it anyway..

Why only Toda and Jun?:confused:. I would look into the skunk2 pro 1's if he keeping it stock compression.

[VTECMACHINE]

He won't use US parts...

[beeza]

Can I ask,
How practical are a stage 2 cam for cruising around at say 50-80km/h? A daily driven car,I mean I can't see it not being but...

[VTECMACHINE]

This is what I am asking LOL.

He wants more hardcore cams... but apparently can put up with a bit of crap, haha.
Anyone used the JUN cams before?

[Limbo]

i got 1 thing to say, vtec.
Generally if you stay under vtec all the aftermarket cams copy the OEM profile. Its only the vtec cam that is more aggressive

[Lowa]

As said many times before its more of the combination of parts, not so much the cams alone, as long as you have the right compression for the cams, cam gears dialled in, and someone that knows how to tune, it all should run well at any rpm/speed , if you have a look on HT, you'll find alot of the guys are driving the cars as they were stock, just with more power

[beeza]

Thanks mate,makes perfect sense!

[delsol9000rpms]

As was said earlier, most aftermarket cams copy the stock honda low cam profile. However the Toda cams have a mildly increased low cam profile for better low and mid range power and torque..

SK2 is not US, they're made in china mate..:D

well said!!!:thumbsup:

We are running a mild cam and making over 150kw. Its the combo of parts to maximise the power!

U sure not made in taiwan??? or they used to be anyway lol, nothing wrong with that, its not were there made its how there made

I dont know if u can say that dude, my zspeed cams run at around 245-250 deg duration on primary and secondory but at about 9.xmm lift, then 304 with 12mm/11.5mm lift on vtec, thats at minimum 1mm too, im gonna have fun lol, at the end of the day no matter wat u got it partly depends on the tuner

O,Great to hear! :thumbsup:

Is it easy to stay under Vtec,I mean do you have to be 'soft' on the accelerator or you can drive quite normal like?

How street friendly are the Toda c's?

[Benson]

Toda C's on a stock ITR motor is horrible... Toda C's are meant for a well bult B18cv with compression greater than 12:1

[beeza]

Thanks Benson :)

[delsol9000rpms]

i have toda spec c's on a stock b16a block.. less than a stock type r's compression.. low down power was much better. check cammed motorspecs thread in allmotor for the difference in down low power...

[beeza]

Thanks mate,yeah the c's seam more suited to the b16's.

Not questioning the result you got from your B16a, but from my mates experience with Toda C's on a stock ITR he felt it being lazy until vtec hits @ 7000rpm. He proved this theory on the track as well

[delsol9000rpms]

your mates car should of made power everywhere. one of the biggest reasons why the spec c cam isnt suited for a standard b18c is because it tends to keep on making power way above its reving capability, which isnt good cause you'll blow it up. maybe they were set up wrong...

[jansenrw]

I actually have the spec B's in my car, not a "he said- mate of mine's experience...,"

They work very well, but then again, I have a mildy built engine with upped compression. Midrange and daily driving is where they come into their forte. I can do a leisurely mountain run outta vtec as I have more than enough midrange. You adapt to how you drive the car as each cam will have different power delivery characteristics. My .02, the spec B's are great - but it would not hurt to upgrade your valve train either.

"I can do a leisurely mountain run outta vtec"

Nice description!

That sounds sa-weet,good one :)

i picked jun stage 2, but ive never driven a toda spec B, but ive been in it.

jun stage 2 is quite aggressive. it says you can use it with your stock ecu, but it gives pretty bad idle.

does spec b toda give good or okai power before vtec.?

Any car can start on a stock ECU if you dont change injectors size.

But if your were to drive on them with the stock ECU, im not so sure on the driveability

AS above

[delsol9000rpms]

spec b's on a b18c7 = awesome power everywhere right from idle...

[hisoka]

ohh ok~ yer jun stage 2 give pretty bad idle, but reall awsome top end.

[TODA AU]

Spec B's work great on std B18C,
This is well know & not disputed by many at all.

Now spec C, C2 & D share the same low cam as the spec B
All of these can be uses with the same low end power increase & off Vtec power & drivability.
The critical point with TODA cams is installation.
If they're installed per cam card, they work & work well.
The instructions are supplied with the cams & they are clear & specific.

Lowa sumed it up pretty well... (+1 rep) :thumbsup:
