if i want to make athe hw-itb https://www.homemadeturbo.com/tech_p...itb/index.html
what do i need to upgrade in my engine it's a stock b16a2

 

nothing internally, just do as the write up says, you may want to get a vafc or some way to tune it

 

accually i just completed a HMT ITB set-up on a B16. it was very very simple, and no tuning was required. we also used honda 954 throttle bodies, which was in a sense a plug and play system. if you need any furthrur help, ask.

but, yeah, most everything you need to know is in the link above. the MAP sensor is plug and play, if you use honda TB. BTW, we did also make our own manifold. the stock IM worked, but we had a SMALL vacume leak. nothing big, but it was minor. we just tried to perfect it a little with the homemade manifold.

 

no tuning is required, but to get the pull potential of the itb's you would want to get it tuned, it's taking in a lot more air than your regular cai.

 

yeah, your right, but my point was no tuning was really necessary. It did run a little rich, but it wasnt to much. We didnt hook any A/F meters on it, but it seemed to run just fine.


I had a D16 ITB set-up that was almost complete....long story.

 

If I was going to do a ITB setup on my b16 i would put a set of ITR cam's in. It would make for a decent All motor setup.

steve. i have been told and read many times that ITR cams are useless unless you have the valve train to go with them.

 

im gonna have to punk some frona bike next time i go to the junk yard...

 

Lots of people make good power with ITR cams and stock valve train. ITR cams arnt aggressive enough to need aftermarket valve train.

here was my ITB set-up.

I had in it what I sold it for.

I think was $150, dont remeber.....

I got the ITB's from Ebay, everything else came from Napa.
I had the honda CBR600 F4i throttle bodies.
