home made b-series ITB???
i'm a little mental right now but i was wondering if anyone knows where i can get
things for my b16a one being ITBs and dont wanna pay a million bucks to get
them cause i'm a broke S.O.B. what all will i have to do to build my valvetrain to
still make it streetable and reliable also i know of some CBR600rr throtel bodys for
90 bucks what all will i need to rig them up or should i go with diffrent ones? what
cams would i need and what all would i need to tune it my car i obd-0 with a PR3
ecu? My buddy told me to get ubberdata but is it what i need? if anyone knows of
any website links or anything like that PM me or something. if there is any down sides to it i would like to know everyones opinion and appricate it.
p.s. As you can tell a cant spell

Here's what I know about do it yourself ITBs...
You don't HAVE to upgrade cams or valve train to use ITBs, they just go in place of the intake manifold. No internal work is required.
Here is a link to a thread with information on several sets of ITBs you might find on eBay or in a junkyard or something.
http://www.homemadeturbo.com/f...723.0
It looks to me that the CBR600RR3 ITBs have an inner diameter of 37mm. From what I know the expensive TWM ITB kit uses a 50 or 52mm inner diameter, so 37mm may be a bit small for even the B16.
If you want to run Uberdata you'll have to convert to OBD-1 which will cost money and require a decent amount of wiring and conversion parts. Your only other real option (in my opinion) is to run BRE in your PR3 ECU. Since you use your existing PR3 ECU, there are no conversions required...you only have to solder in a ZIF socket so that you can chip it.
You can get more info about BRE here:
http://forum.pgmfi.org/viewfor...64190
Since you're broke, this is a nearly FREE alternative to expensive setups like Hondata and what not, and it does the same thing basically. If you don't have an account at pgmfi.org I highly reccomend you get one, as there is infinite amounts of information on that forum.
The general consensus on ITBs from what I've read on this forum is that your gas mileage will decrease but your midrange and upper RPM range power will increase. Since you'll be using them on what sounds like a stock B16 you may not notice a very big increase, if you get an increase at all. A more cost effective way to increase power would be to either:
A.) Increase compression
or
B.) Add camshafts
However the best gains are made when both of those are completed, that being adding camshafts and increasing the compression. I understand that you may not want to do any internal work on your motor...but this is just a suggestion.
As far as actually mounting the ITBs to the engine...this is kind of the tricky part if you don't have access to a lot of tools or atleast a welder. You have to cut the plenum and some of the runners off of a stock intake manifold, and then weld additional tubing onto the runners, then the ITBs. You could also buy an intake manifold flange and weld runners onto it, then weld or somehow fasten the ITBs to the runners.
Don't forget about actually taking the time to tune the ITBs, run all the nescessary vacuum tubing, create all the nescessary throttle linkage, and find a way to tune it by either TPS or vacuum.
Needless to say, this is not a project for somebody who lacks experience with this sort of thing. All that said, this is just 2nd hand information I have collected by browsing several forums, so don't take it as the word of God or anything.
