I don't know if this is old news here but . . .

TODA recently released an "Engine Kit" for the K20A and K20A2 engines. It composes of a set of TODA spec A cams, valve springs, and an ECU which is tuned for the cams. HP gain is about 50hp to the wheels with exhuast, header, and CAI. This should bring a stock RSX-S to about 220whp. It's a pretty impressive piece but IMO a bit expensive at $2,350, but TODA is top notch quality. The engine should show more gains with ITR intake manifold and a bored throttle body. This is good stuff for K-series people...I can't wait until TODA B and C cams come out!!!

i want that kit! But I think it's alittle pricey. I was told hondata was working with toda. I rather pay $200 for a reflash than pay $600 again.

 

Available for: K20A Type-S

TODA Racing began development of the Honda K20A engine in mid 2001 in order to prepare complete race versions of this engine for teams competing in the grueling 2002 Japanese N1 Endurance racing series. As with all TODA products, development first takes place in the realm of professional motorsports. Feedback from the N1 race teams was used to further improve the race engines as well as to develop TODA's street parts for the RSX.

Our Engine Kit for the RSX Type-S includes TODA Spec A camshafts, TODA valve springs, and a special reprogramming of the factory ECU developed in conjunction with Hondata. The factory ECU must be sent in to us for reprogramming. This special ECU program is only available through AKH Trading/TODA Racing USA and was developed to maximize performance of the camshafts. The ECU program uses special fuel and ignition timing maps, 9000rpm redline, modified VTEC Activation, and modified VVT camshaft timing. Because all parameters are optimized through this special ECU program, dyno tuning of the Engine Kit is not required. This is especially beneficial to users who don't have access to a dyno facility or an experienced tuner, and all users benefit by saving the time and money associated with dyno tuning camshafts which normally ranges in the hundreds of dollars.

DRIVING IMPRESSIONS

The goal of our Engine Kit was to increase power levels from the stock 200hp to over 250hp while maintaining stock derivability. Starting the engine you won't notice anything different, even the idle is as smooth as stock. Under normal driving conditions you'll immediately notice the increase in low end and midrange torque. Is this still a 2.0 liter engine? Keep the throttle down and the engine pulls towards redline in race car fashion with an unmistakable roar. While peak numbers are too often used to measure engine performance, a far better indicator of an engines capability is the overall power curve. A vehicle equipped with our Engine Kit produces more horsepower AND torque starting from 2000rpm! No loss of torque or horsepower at any rpm.

ORDERING PROCEDURE

Once a customer places an order, AKH Trading/TODA Racing USA ships out the camshafts, valve springs, and a UPS Next Day box (for the ECU) to the customer. Once the customer receives the box, he/she removes the contents and places their ignition keys, immobilizer, and ECU in the UPS Next Day box and sends it back to us. We receive the package, reprogram everything, and send it back to the customer. All UPS Next Day shipping costs are included in the price of the Engine Kit.

Just a Note in there. AKH/Toda USA And their Authorized Dealers

 

toda is great!!!

 

Here is the dyno sheet from the Toda wesbite.

Is the Toda header out yet?

 

http://www.todaracing.com/products/h..._manifold.html


Available for: K20A Type-S and Type-R

Information coming soon...

 

THese are good power gains but it looks like it TODA used a engine dyno which may not account for power lose through the tranny. In addition the header that they use is a prototpye and may flow much better because of the shape than what will be released. IMHO

Plus the dyno charts say Fly Wheel torque and HP graphs.

I saw your exact same post at clubrsx. They used a dynapack, which measures at the wheels. Look at the dyno sheet on their page, it says dynapack and at the bottom it says "Church Auto Testing" located in Torrance, California.

And for some reason Dynapack always says "Flywheel" at the top of the dyno print outs while it's actually measuring wheel power.

That 220hp is wheel power, look at the stock numbers, it base lined at 170hp. How can 170hp be flywheel on a Type-S?

Good point, however, that header has to be a major factor in the HP figures. THeres no way the one in the picture will fit any RSX. I just wonder if those cams are worth $500 more than ITR cams.

 

Well the picture that i have up top of the header, is of it upside down. Toda would not design cams that would not make power, and with that, they would not design cams that wouldnt make more power than the stock ITR. Remember these can be used on both Type-S & Type-R. With an ITR Intake manifold on the RSX-S that has the engine kit, it will benefit from the flow that the stock intake manifold cannot provide. It should make the power curve you see on dyno above a little higher prolly about 700rpm as posted on clubrsx by another person. If you have a Port job done that you will get even better numbers. Toda prolly wont releave Spec B cams for a while, but when they do, i know for sure that it will prolly be the same improvement that the B-series Spec B cams have over the Spec A cams.
B-Series has had 12 years of development, the K-series has only had 2 years. Time will provide us with MANY more power maker parts.

 

WHy would TODA put the header on upside down? Would it even fit with the bolt pattern?

That I agree with, do happen to know the specs of the ITR cams?

 

Cam profiles :
Cam lift : 6.9mm IN / 6.5mm EX
VTEC cam lift : 12mm IN / 10.5mm EX
VTEC Intake cam profile :
Open : ATDC 12º (VTC max. advance 50º)
Close : ABDC 77º (VTC max advance 50º)
VTEC Exhaust cam profile :
Open : ATDC 15º
Close : BBDC 45º
Primary Intake cam profile :
Open : 25º / 30º ATDC (VTC max advance 50º)
Close : 45º ABDC (VTC max advance 50º)
Primary Exhaust cam profile :
Close : BTDC 45º
Open : BBDC 30 º/25º


In this dyno, the top is DC5-R the middle DC2-R and the bottom is the iS(DC5 base). Just a stock for stock comparison of the 3 cars.

Wow, incredible stuff.

It appears that the K20A is beginning to surpass F20C power levels, yet at lower RPM - that's quite a feat!

 

I cant wait to see that this does for the K24 in the upcomming TSX

 

i have been waiting for toda cams forever but I donno if I'm gonna get them now since I have seen 216 to the wheels on the same dyno with type r cams/k20 reflash, h/i/e.

For $795 that is a lot cheaper for me(considering I already have hondata so I would have to pay $200 for a reflash)

 

that looks like a blackdog header for a neon...

i was wondering why no one has tried that design yet...

the blackdog race header has like 5 foot primaries

makes tons of power on neons...and they're somewhat similar motors to the rsx (without vtec of course )

 

Actually, the dynapack DOESN'T measure HP at the wheels, it measures it at the HUB! A dynojet measures HP at the wheels.

 

Good point Black! However, we'd have to see a comparison of the entire graph and not just focus on peak power. The package is expensive but at least you know it is quality stuff. I really want to see this oackage with a ITR or manifold and bored TB.

 

ya I would like to see that too. I am pretty dissapointed though, I want a hondata reflash for $200 not another $600 flash.

I am sure that rsx rips though!
