will a USDM ITR header fit on a JDM B16A without mods? mods needed? or will it fit at all?

 

This is the header I want to get for my Rex too. Its supposed to fit, but then theres the thing about the two o2 sensors. Will have to make a spot for them I think..

 

this regarding the 4-1 JDM 98 specs ITR headers....(4-2-1 will work without problems)
it does fit...the front crossmember will need to be notched/cut out slightly otherwise it won't fit....the issue thats usually a problem is the road clearance if the car is low and the mount kit positions the engine even lower scraping will occur...the other isuues are 2.5" cat inlet...will need a test pipe or a aftermarket cat......2nd o2 sensor for non-obd cars will need to be welded in ....

 

i thought the USDM ITR header would bolt rite onto a B16A?? hmm...maybe not??

 

also i looked at the USDM ITR header...and their's only one O2. Has anyone done this b4?

 

Not sure if it bolts on, but if it does and anybody wants one, email me and let me know. Thanks.

 

Yes, it will fit. But you will need to:

1. Notch the front crossmember about 1/2 inch.
2. Either: A) tap that O2 sensor so that both O2 wires run off it or B) install a 2nd O2 sensor
3. Buy a 2.5 inch cat OR a transition pipe (2.5 inch collector to 2.25 tip).

HTH.
