I was wondering if anyone has a Toda Racing Sports Injection Kit. I am looking on some feed back for this product to see if its really worth paying $2650 for this. I know that using this product requires a fully programmable engine management computer, different fuel injectors, and modification to the engine wiring harness. Is it worth the gobs of money that you'd put into purchasing all this. I have not found any dynos, and every time I call them I get a machine.

what is your setup? or plans for your setup?

I'd just turbo...

 

I plan to change my internals by replacing the camshafts, valve retainers and springs, pistons, connecting rods, gaskets, etc. I actually got ahold of the guys at Toda Racing and they said that it is best to use the products they offer if I am to use the sports injection kit. But then he said that alot of the componets they offer are not good for street/strip, mostly all-purpose race engines. I guess i'll have to re-plan my setup... , i'm going to start looking into Crower Cams for a different setup. I'm told that they offer good componets for daily driven cars.

 

ITB's are not practical for a daily driven street setup.

Tuning is a much different territory, because you are above 0 hgkpa from the MAP after about 10% throttle, so you really have to concentrate on partial throttle tuning compared to a plenum style/single TB tune where you can almost get away with not caring about partial throttle.

The power gain with moderate compression isn't that high either, more than your standard intake manifold, but to really get high power you need high compression. The TODA kit is really meant for bigger bore also, they have particularly large throttle plates, (54mm?), so they need a bunch of air to be efficient at low RPM's and low throttle.

The throttle response is probably the most attractive part of ITB's for most people on this board, and of course the engine bay bling.

If you are seriously entertaining the thought of ITB's, you should look at a 45mm size for 1.8, or for higher compression, 50mm.

For what you're getting with the Toda kit, it's not really worth the price. Jenvey offers a superior product at a much lower price, but you do have to look at your setup and how it will benefit what you already have. I disagree with anyone who states that ITB's aren't practical for daily driving as I've seen several setups that made great power and were daily driven with no issues.

 

for the price they are not worth it at all. i just did a homemade itb setup w/ 40mm cbr throttles and the daily driven/partial throttle **** is actually pretty good. i ma just tuning with a vafc and i have it nailed down. the don't get any bogs or anything like that. i have two nipples on each runner, one running to a map sensor and the other running to the golden eagle vacuum box for the brakes. everything works great. it starts up fine and idles at 1000 all the time. intial throttle tip in is fine and i really don't have any complaints. the whole setup including the vafc, fpr, and vacuum box cost me only $400. i am going to tune it using a wideband this week. oh yeah here are some pics:







if anybody has any questions, feel free to pm me.

Thats what everyone told me when i converted to sidedraft carburetion. ITB fuel injection is practical if the person working with them knows what they are doing, and is using the right tools. Same story with my Mikuni conversion from efi. Everyone scared me, but they do just great, cuz I put the time into 'em to make em run nice.

 

i guess that is what it comes down to. knowledge and dedication to make **** work right. i had some tps problems with mine, but i figured it out.

 

People "say" a lot of things, but when it comes down to it, the majority of the people who are "saying" things have no experience with what they're talking about. We ran 42mm ITB's on a stock B16 with a stock P30 ECU for 5 months and the only problem we had was a messed up intake manifold gasket.

I'm saying that the average person on this board does not have the money and dedication to tune correctly using ITB's. Practical is a very broad term and I should have choosen a different word, but I meant that simply purchasing the product, installing them, and tuning WOT will not create a "practical" daily driver. Many hours need to go into tuning partial throttle maps before they become an efficient setup, the OBD1 honda computers cannot process information fast enough to compensate for the change in vacumn at partial throttle loads, and most people convert to OBD1 for software such as Hondata and Uberdata. ITB's, if tuned correctly, are far superior to plenum/single TB setups in terms of mileage, power, and response. Having equal air distribution is indeed a big bonus that our stock plenums suffer from...and most aftermarket plenums still cannot perfect.

Thank you for the correction.

very well said. i agree tenfold.

 

if its not plentyful, it is usely not practical. but why be practical?

 

where did you get the resources for doing your individual throttle bodies. I know of a couple people who say its better and cheaper to set up the ITBs yourself.

BTW: nice engine pics.

Motorcycle throttle bodies are commonly available at motorcycle junkyards, speedshops, ebay, and sometimes in the Honda-Tech classifieds.

yeah i got mine off of a 929 cbr. the manifold is just a standard pr3 cut and rewelded and attacthed to the throttles. the vacuum box i got from camp1320.com(a big to tom)
