Hey all, looking to build my b16a2 swap which i have sitting in my garage. anyways i have 97-99 ITR cams, but i will only be using the exhaust (all yr ctr/itr exhaust cams are the same), i'm recieving a ctr intake cam soon and tomorrow im picking up Skunk 2 tuner series 5 screw/bolt Adj. cam gears and ITR Intake Manifold and ITR Throttle body. I'm also looking at purchasing a used jdm dc 4-1 (2.5" coll.) header or the RMF narrow replica header which, from researching, is the best bang for the buck. I will be running a Virgin P28 for now, but once i get a tune, thats when i will get a chip installed

Now i just would like to know what you think of this setup and i have a few questions:

1) Is it ok to run a 2.5" collector but use a 2 1/4" itr exhust, kinda on a tight budget and dont wanna have to buy a custom exhaust/muffler. you recommend a cat/test pipe?

2) is the B16a2 fuel injectors good size or should i upgrade to anotherset of used oem honda ones. or RC? also, i would need a FPR, FP Gauge but dont necessarily need a aftermarket fuel rail, correct? i could mount the fpr & gauge on a b series rail..

3) would the itr 62mm throttle body be an ok size or should i go abit bigger?

i understand its a 1.6L and im limited to power with staying N/A but i just want to make a reliable b16 with a clean, reliable, and semi-powerful setup, ANY ADVICE is appreciated.

thank you and sorry, im just looking for the best advice which is why im asking Honda-tech

 

It is a BAD idea to put a ITR intake manifold on a B16A. You will only lose hp

 

you sure, i will be running ctr intake, itr exhaust cams

 

There have been many threads and many dyno's proving this. You want to use the 2nd gen b16 manifold, the P30. It makes more power through and through. In fact, even on a B20 vtec swap, the P30 manifold out performs the CTR/ITR intakes manifolds.

The cams are good, go for them!

btw, the 2000 and 2001 ITR cams are the same as the CTR

 

its a 2nd gen B16a2 swap. if thats the case, then ill save the $250 dude wants to sell me the itr i/m & itr t/b setup and use that towards the RMF Narrow header.
