type r throttle body on a vtir

[papie]

can i use a type r throttle body on a vtir integra? if i can would i have to use the map sensor off my old throttle body or can i leave the one that is on it?

YES you can IF:

1. You bore out your intake manifold opening to at least 62mm to match the ITR TB.

2. Your VTiR P72 engine is OBD2 (98-00 model), that means that your standard 60mm TB doesn't have a fast idle valve at the bottom. (otherwise it wont idle properly)

3. You get an ITR throttle cable to re-orient the throttle opening, or swap over the the D-shaped throttle cable nipple holder from the stock 60mm TB to the ITR TB because they both open the opposite way.

The map sensor only needs to be changed if its faulty, otherwise its identical.

If you're upgrading TB upgrade your IM and intake as well, you'll feel a much better improvement

mine is obd1 it dose have fast idle valve at the bottom so is this going to be a problem?

just another question if i was going to get the type r tb and the i.m would it straight swap over with my vtir tb and i.m or do i need to change anything else? would it be alotta gain as well?

[dougie_504]

No it won't be a lot of gain. Maybe some noise and a little more responsiveness, not a whole lot more power.

[nwa111]

what about the skunk2 tb and i.m , just some noob question i want answered

[pablos8]

After I installed my cai, intake manifold and skunk 2 tb I felt a massive increase in response and top end power

[MikeyG]

cant use type r TB on b18c2 intake manifold.. need skunk2 intake type.. then use type r TB and you should be set

Love it, but after a few weeks I'm pretty sure it's just that I need a tune man. I'm using a pre-tuned OBD0 ECU from Japan, apparently set for I/H/E and cams/port job but not for larger IM/TB or re-welded combustion chambers. It goes really hard from 6000-9000 RPM and is much perkier down low but is really lacking in the mid-range, feeling almost laggy.

Timing adjustment should help once the head is worked in a bit, then the Walbro and tune should top it off. Really hard to judge the benefits at the moment as they're far from full potential.
