Somebody know what is size TODA ITB size? It is 48mm,50mm or more?

Why TWM made 50mm for B16A and in UK using 42mm Jenwey kit in B16A?

 

43mm @ the plate, 48mm at the horns if i remeber correctly.

Very nice ITB's.. they're perfect for 1.6L/1.8L

50's for a 1.6L is a bit much.

Jenvey knows what they're doing.'

Jenvey or Toda's would be my top choices.

TWM isn't even an option.

 

the smaller diameter at the plate means nothing, prolly better than bigger only because its higher air velocity/lower pressure ... I used Todas on a built 2 liter and had no problems making 185 in torque at the wheels. Similar motor with the 50mm TWMs made similar torque too.

Still trying the Jenveys to see right now, but they are smaller than the Todas but seem shorter runner length more inline with my motor specs.

thank for help! Good info!

Have you ever seen dyno sheet before/after ITB customs made (like GSXR1000)?

I ask about it, becouse many poeples made customs ITB, but never saw any gain resoults? Why? customs made ITB is ****?
I saw also many customs ITB for sale

 

I have a set of custom ITBs with the 4AGE bodies, I'll prolly get to dyno it before and after one day, its a lot of work for me to do so.
Not sure why some dont get better results but ... its probably because they lack certain info and try to use with stock ECUs or reprogrammed ECUs that don't accomodate for ITBs, I usually reprogram customers ECUs for ITBs and the maps are very different from a regular map used with stock TPS and manifold.

thank you for help,

but example

K20EG using ITB with hondata re-flash and VAFC II.

I don`t have idea how it works!


Do you know why ITB has different injectors place?
I saw injectors installed in stock place, some other brand made before or after butterflys.

It is big different for power gains?

 

Aside from the size of the runners, the injector placement is probably the next most important factor. The higher up the injectors are on the runners the better the fuel will atomize. Better atomization = better burn = more power. So far I think the Toda's have the highest placement, I could be wrong though. Cheetah is our ITB connosiuer (sp?) here

Also about engine management, I think if you've spent the money on building the motor, the ITB's and all that jazz there's no point running VAFC or maybe even Hondata. I would pop for a stand-alone system and a good tuner!

I've owned both sets of itb, Toda/Jenveys.

and the Jenvey's are much larger than Todas by far.

Yes Toda does have the highest injector placement.

 

does anyone have dyno charts available for either toda or the other 1? I am considering this rig, but I have 4 million questions about it ....

Spill the questions and we'll see what we can do

 

there take a look

well.... does it actually increase power across the whole band as toda has claimed in the past? or is this a high compression, Idle like a stroked V8 and only have power over 6000 rpm setup?

how much does it actually increase HP?

what else has to be done other than standalone engine Man?

will it even run a little better if the rest of the motor is left stock? or is it full build up or nothing at all...


I will post the ones i forgot as they come to me....

Rumor also has it the ITB rig from an F4i will work well here, same sensors and such

 

You can get the Jenvey's from 40mm- 51mm, straight bore or tapered bore. The 42mm kit is just shelf stock but can be ordered with diff. options, and more cost.

 

so who exactly is jenveys... have a website?

 

Aren't TWM's on the top nine of the ten quickest ALL MOTOR cars?

hahahahahaha that was funny. probably very true.. whoever said they would pick the dinky toda over the twm for maximum power output is on a good one.. we only sell the twm's and they work great for high output motors.

 

TODA ITB suck *****!!!!!

hey max, I've had pretty good results with the Toda ITBs as small as they are they do perform evne on 2.0 liters. Not saying TWMs would have made more or less, just know the Todas are not as bad as some may think

here is a sample dyno on one of my old all motor cars with an 89 crank :

nice, what is the compression of the motor?
