I want to change my camshaft to gain a few extra power, but don't want to put too "big" camshafts because in the track that I race has only very tight curves and the torque is very important here, I was considering the Toda Spec A or the Spoon cams because with Spec B/C I will lose torque exiting the curves. Which did you recommend me to buy? between Toda Spec A and Spoon... will I feel the power gain with it? I only have I/H/E and stock ECU in my JDM ITR

 

Toda makes the Spoon cams meaning they are identical in quality in very comparable in performance, so which ever you can find for cheap get them. They are a great cam and should be tuned with some type of fuel/vtec computer at the sametime of installation for the best results.

 

Some good information on this thread:

Also, people tend to speak highly of the Buddy Club Spec 3+ cams, you may want to take a look at those also....

Maximus is right, you should get something that will enable you to tune the fuel/timing like hondata/uberdata/crome and possibly some larger injectors....

What makes you say this?

Properly tuned spec b and c's will have a seamless vtec crossover and exhibit greater torque and horsepower across the board when compared to stock cams/ spec a's. Their wider powerband will also enable you to stay in gear longer without having to upshift (assuming you tune and have a programmable p28).

What i/h/e are you currently using? You might also consider upgrading those to the top of the line stuff as it's less intensive (if you aren't adept at cam installs - which aren't difficult, but can be daunting if you've never attempted such before).

George Knighton had fairly good results with comptech icebox, sms longtube 4-2-1 header, and sms 2.5" mandrel bent exhaust. Over 190whp I believe and a very flat torque curve on the dyno.

Austin also had very good results - also in the low 190whp range with mugen intake, hytech longtube 4-2-1 header, and hytech 2.5" mandrel bent twinloop exhaust.

If the type of racing you do allows it - a final drive upgrade might also be in order; jdm 4.785 and ats 4.929 each have their advantages over stock in low speed corners.

And finally, a well tuned jrsc setup will net you the most torque and lots of fun on the road course..... Several here have run this setup intercooled with good results. Of course there are a crazy few like Austrian Type R and Chris F who road race the **** out of their itr's with turbo's. This seems to be the craziest method - I mean how many porsche's and ferrari's do you want to make look silly?

Where did you hear this?

 

Black R, I remember hearing about the toda/spoon issue a couple years back I say at least three. If spoon does not outsource the cams to toda then that is my mistake.

Considering the user is located in Guatemala, I don't see anyone specializing in hondata tuning in the area so george knighton or austin type numbers don't seem too possible. However, a typical tune of the gears, timing, fuel and etc from a typical tuner will still net you great results. What ever the number you make RicTRD, you will appreciate the power that comes about.

 

Yes you are right, the Spec B or C well tuned has more power but in high end, because we have experienced with Spec B+ in low rpm it chokes on fuel and in our track we have curves that the rpms falls to 3,500 rpms and we need good torque at low rpm...

I'm using AEM CAI, 4-1 JDM headers and Kakimoto exhaust

And we have a huge problem here in Guatemala, we don't have dynos !!!! only butt-dyno hahahaha

that sucks, but sometimes the butt is all you need!

 

from what you're describing, a higher final drive (98specR or ats) will be well worth the money.

 

3500 rpm?? DOWNSHIFT!!
