HF manifold

I mean HF sorry folks!

Hey guys, I'm in the process of boosting my 96 coupe d16y8 and I'm on a tight budget. Now I have been looking into manifolds and have determined that HF manifolds can't be beat for the price (plus they are oem). Now I have a few questions which i have searched and not really found exact information. I know on the d16y8, apparently the 2 o2 sensors are 1. below the exhaust manifold before the headers, and 2. in the cat. Correct? Now the HF manifold has an o2 bung at the top of the manifold. If i were to get an HF manifold, will the o2 sensor that is below my stock exhaust manifold go there along w/ adding some wire to the sensor? And if it does go there, would i need an o2 bung in my downpipe if i have it up top on the HF? And say if i got a log manifold w/ no o2, I would need it in the downpipe obviously? Thanks a lot for you help guys!

you mean HF manifold.

88-91 CRX HF
92-95 Civic CX.

you get a HF manifold then go to BMCrace.com and they sell adapters to adapt almost any turbo to it.

best bet would to be run the o2 after the turbo in the down pipe. but teh HF manifold has the hole for a o2 on top so you can use it

Sorry guys, i mean HF

its cool, some people would have asked what you are talking about.

HF manifold is great for budget boost.

Well are you going to use a piggyback and stay obd2, or convert to obd1 and use a chipped ecu? If you go obd1 then the cat (downstream o2) isnt needed. But there is really no reason not to place the o2 up higher in the hf mani instead of downstream, just so you can get as accurate a reading as possible. (if it can handle the heat, I would research that)

Hmm. I have a HF with a T3 plate welded to it. I planned on boost at one point, but I can't afford it. If you are interested lmk.
