the plenum inlet on a jdmh22a? obdI not sure what info is needed but i just wanna know what size the hole just past the tb is?

 

Why you want to know? It's alittle bigger than the OEM TB; like 62-64mm.

 

im kinda confused on the question of why? im sure everyone knows h22s suffer from suffocation. bigger tb would need the plenum ported to actually benefit so...
like i said seems like a weird rebuttle... fair but still weird

 

I'd do the manifold if you plan on doing a TB. I recommend a Euro R with a big TB. That's what I'm running my butt dyno loves it. It's kind of weird, it feels like my torque peaks at 6800ish. Obviously their's more power in the midrange but my fuel values peaks right about their so...

 

i have a ported jdm manifold already. so im just moving further out to even things up. so thats why i wanted to know

 

It is exactly 62mm's. I just had mine ported 6mm's to match the taper on my Omni Power TB. The JDM Euro-R and Type-S have a 64mm opening. Just for confirmation, I have 3 h22's in my garage right now. 1st is an obd1 udsm w/10:1, 2nd JDM obd1 w/ 10.6:1, 3rd is an OBD2 Euro-R. Anyone need any specs just let me know before I put them back together. I'm currently in process of putting them back together.
