I just bought some TWM itb's off a member here and well no instructions so I am lost, got everything with them and also they ain't the 2000 series the older model. and well TWM ain't that quick to response and like to try them out this week I have off work.


I need to know how to install completely to my b16/ITR head everything in detail as the sensors, brackets, and log manfiold I am lost on.....

 

why don't you just ask the guy you bought them from

 

yes but his was a obd2 engine and mine is a obd0

 

why don't you just add the fact that it's a rare JDM OBD0 built for Australian N1 team only and really make it a challenge and harder for yourself? LOL

 

Where are you located?

 

To help this thread along, I will give some more details. Here are the ITBs that we are talking about.






















The TPS sensor is already rigged up on the ITBs.


For the MAP sensor, you will have to use an OBD0 firewall mounted MAP sensor that uses a vaccuum line to read the manifold absolute pressure. Any 88-91 civic or 90-91 integra has one of these mounted on the firewall. The vaccuum line will run to the vaccuum log.

This is the vaccuum log:


Vaccum lines need to be run from the ITBs to the vaccum log. There are little nipples on the ITBs in each runner that must have hoses connected to the vaccum line. The brake booster must also hook up to the vaccum log.

You must also deal with the Idle Air Control Valve (IACV) which has coolant lines running through it. Some people tell the ecu to ignore the IACV and then you just have to loop the coolant lines. Other people make a metal plate for the iacv and then run vaccuum lines to the vaccuum log. Here is a picture of such a plate.



Hope this helps.

 

so far it is just a tad but still don't know how this all gets hooked up like the lines

I guess I need a diagram or something this is tricky

 

something you need to consider. tuning.
if you plan on staying obd0 and run something like turboedit, etc. you will have issues.
I am trying to tune a set up now with obd0 turbo edit. The main issues you will find are, 1, there is no real stable code for map/tps so all your load is based off the map signal. 2. although, you will pull good vac at idle, and that can be tuned, after about 20/25% throttle you loose your vac sig because of the itb's So tuning off a map sensonr for load will be difficult if not imposible at part throttle. You may be able to narrow it down to a few columns but still will never be like a stock car with itbs. 3, tip in enrichment. There is no provision for it in obd0 turbo edit. When you blip the throttle and suddenly loose vac, the engine goes lean for a brief moment.

The best way to avoid this is to either convert to obd1 and run crome which has MAP/TPS based maps, tip in enrichment, etc, or to run a true standalone.

as far as understanding the physical components, study each system there(fuel, trottlecable, vac, wiring, etc.) and try to understand exactly how it works in the car now and how your going to hybrid this over to that. Its not too bad of a learning curve.

well I am obd1 w/s200 hondata don't know if this can work

and also liek to know who can help me or what shop I can take this car to get fixed misfiring issue and to tune these things or ecu cromeing then...

magic mountain area.....

 

I think the one's you have are for a VW and someone rigged it for a honda motor? check out TWM site http://www.twminduction.com if you need any help please give me a call my number is in my sig. I am a master distributor for TWM and ill be glad to help you guy's/girl's on any question's you have about there itb's. Highend autosports

i doubt they are but thanks trying to get a hold of u Mike

 

sup man, i recently bought twm itbs for a type r/b16 head and they def do not look like that, i havent installed mine yet either

 

the silver line coming out of the fuel rail should go right to ur filter, the regulator should go onto the other side of the rail. the abrb side of the regulator connects to the same fuel hose that you had going to ur stock fpr. the intake air temp(iat) sensor goes on the bracket hanging over the velocity stack. just leave the iacv hanging still connected to the ecu and coolant. connect the hose that used to goto the iacv from the tb right to the other hose that went into the tb.
the vacum log normally has one small line going to each of the runners, another small one going to your map sensor, one big one going to the brake booster, and another big one going to the pcv valve.

 

oh okay this is helpful thanks KraZEteggIE, I am more the diagram type person but getting the idea now

Nah they are just the type that replace your average Weber DCOE, Mikuni PHH, Dellorto Sidedraft carbs. Thats why the manifold looks like a straight up DCOE sidedraft carb manifold (besides the wierd angle at the flange). These are basically just the universal version of TWM's throttles, since there are so many people who run sidedrafts and would like to convert to efi.

This is the similar to what SOHC users must do if they want to use TWM ITB's. You need TWM or Pierce sidedraft carb manifold manifold and a pair of these 2900 series throttles.

So no, you dont have the 'wrong' throttles, but the original owner could have just went with a pre made kit in the first place since they do make one for the b16 head. *shrugs*.

I am thinkin maybe you jumped into this whole ITB game without enough research perhaps? I'd just put a hold on everything and read, and ask questions until you know everything thats going on.

 

thank you sir

may just do this

or may just sellt hem and stay intake manifold style

don't knwo research owns me
