I am looking for a chart of a ITR w/ i/h/e & some toda spec a's nothing else besides maybe camgears, vafc, ecu etc...

I also wanted to see how many people have ran Toda spec a's on a factory ITR valvetrain. I am assuming it is safe to run a factory ITR valvetrain on a set of toda spec a's....

Let me know where you guys purchased you're cams & what setup & numbers you guys are putting down etc..

Thanks,
John

 

i want to know that too

 

John, if you do not plan to rev the engine past the factory rev limit then the valvetrain will be just fine. The factory valvetrain is only rated at a conservative 8,400 RPM redline, but may reach numbers higher but then the reliability goes down. You should be able to use a stock timing belt also, but I recommend you replace it with a new one. Don't take any chances on your timing belt or you'll end up with a bigger problems if "anything" happens. And from what I've seen and experienced, anything can happen.

Unfortunately, I do not have first hand experience with the Toda A's. Black R has a set, but I'm not sure if he installed them or just had them laying around. Black R is the official Toda Warehouse. If you ever decide to purchase a used set, please contact Black R. He has more in stock in his house than AKH.

 

yup Kenny is running the spec As, untuned, on stock valvetrain...they seem to run great as is

 

Hmm... I thought an OEM ITR ECU program had a 9k revlimitter am I wrong ?
So toda spec a's on a stock ITR valvetrain should be fine if you keep it under 8500?
That is kinda what I assumed.

The USDM ECU is at 8,400 and I'm not 100% sure where fuel cut is. I've known of people shifting past 8,500 but that just might be the inaccuracy of the tach itself.

Cams don't limit how high you rev your engine. Your ECU and Valvetrain does. With that said, the bottom end does limit you but most of the time the stock bottom end is able to rev to 10,000rpms. My bottom end is stock and it's fine.

 

I have been reving my b18cr to 9k thinking the factory revlimitter was 9k.

 

VTHokie made decent #'s with his itr and spec a's + boltons + vafc & cam gear tuning.

I will post up a comparo of spec a's vs. stock itr cams in the future - untuned and tuned, etc.....

At the moment, I haven't the $ nor the time to go to the dyno.

But you can install spec a's without tuning on a bolt-on itr and run the stock p73 program without any problems.

Here are my comments on the following parts:

-stock valve springs = good for 9200rpm at least with mild cams such as these.

-stock timing belt = no problemo with spec a's. Use helms spec for proper belt deflection.

-stock rev limiter = 8600. Your stock tach is off like most if it reads closer to 9k when it kicks in.

As for gains, expect anywhere from 5-10whp across the board. This number will vary depending on tuning and engine/ fuel management..... I would expect ~180-185whp tuned.....

 

This is with the following before and after tuning:

Spec A's
Mugen Headgasket
DC JDM 4-1 / carsound cat
Field SFC
AEM

 

i have come to learn that most ITR tachs are off by 200 rpms...tach revs to 9,000 but its more like 8,800 rpms

 

GeeReg, you passing inspection in NJ with your Spec A's? I assume you are daily driving your car too?

 

for the price of TODA cams why not go with some Spec Bs

 

I haven't had to go to inspection yet so I really have no idea. And yes it's daily driven. As for why people don't buy B's..because you need springs, retainers, and more compression to make it worth it. That = alot more money.

 

stock valve train is fine for stock rev limit on A and B spec cams.

unless you do head work, you will not need to rev higher anyway.........

 

GeeReg, I don't know if you tuned the cam gears - but if you didn't, I highly recommend that you do.

I suspect that you have as much as 10whp left in the upper rpm band with tuning alone... you are running pig-rich near redline.....

 

No I personally didn't tune them but Mr. Sakai did, so I have a feeling that's about as good as it's gonna get with what I have. I forgot to mention I have a B&M too.

 

.....stock exhaust and cat? Stock vtec crossover (~5600)?

That is most interesting.....

 

Cat is carsound with the stock exhaust. Vtec is at 5000.

 

some of you people are fucken retarded........ya well rev limit is 8400 but my fuel cutoff is 9000RPM........Rev limit is a fuel cut off you numb nutted bastards.......I'm so sick of listening to high school drop-outs rant

this might happen if you change the ecu your fuel wont cutoff till 9~10 whatever the ecu sets, but stock valve is only suppose to go up 8400rpm if go higher you might bent the vlave spring or damage other things unless if you change to toda or others so "Rev limit is a fuel cut off you numb nutted bastards" is not really correct

Whoa easy. I think people are differentiating between the Redline and Rev Limiter/Fuel cutoff.

 

Any more charts ?
I would love charts & full setup lists of toda spec a's & b's
Also skunk2 stage 1s & 2s etc..

Maybe even some em1 cams etc.

 

isn't JDM B18C-R redline at 8900 rpm?
is there any different between JDM and USDM valvetrain? if they are the same then USDM can support up the 8900 rpm too?

and i think if you are getting toda A, why not get the spoon ? coz spoon makes more power than A and doesn't require changine valvetrain

 

Stock redline is 8400 with fuel cutoff at 8500, im going from my 1998 ITR brochure put out by Acura. The stock valvetrain is good to about 9000 rpm. I used a Kenji ECU which redlined at 9k, and took it to that many times over the span of 8 months. All depends on the setup and tuning, but ive seen a few Toda A graphs showing nearly 200whp, hell you can get 200whp on stock cams if you do it right. Speaking of the Toda A's tho, i may be interested in these cams come summer time... anyone have good results upgrading the pistons to CTR's or JDM Integra R's for better results using these cams?

Not true, the jdm itr motor's fuel cut off is 8,500 rpm. The usdm and jdm valve train's are the same for the itr.
