I am going with a D15B VTEC and was wondering if my CX manifold would work? Refresh my memory, I am thinking something is not lined up am I right? (sensor wise or hose wise).

Thanks

 

intake or egaust
because th cx intake manifold sux

Use an ex intake mani if you've already got the intake many off.

 

intake, just for the time being, at least have it running with VTEC and everything and later get an SI manifold or something for a little performance gain.

 

Unless everything is plug and play on the D15B VTEC's for a CX?

Yeah the ex/si mani is the best d series mani imo from 92-95.

 

Yeah but I dont have one lol, I just need it to run fine, not be fast yet.

 

Change that I want it fast but dont need the manifold yet, I want the swap done and fine and later if I want THAT gain I can. But if the stock D15B VTEC manifold works I have it, I just dont know if it all plugs up or if using the CX would be easiest.

 

the CX intake manifold will work, but i would only use it as a temporary replacement.

THAT THING LITERALLY SUCKS

 

lol, so just for final verification D15B VTEC manifold would require modification to use versus a USDM EX manifold right?

 

the only modification is that the area where the purge solenoid is not tapped and threaded or some ****, it's the tiny black thing with a wireplug and a hose running to it. I just left mine hanging there and it's fine.

but it's in the corner of the IM that's closest to the brake booster when mounted

 

you do know the cx dose not have vtec so you will need to switch it out

 

well technicaly your right the manifold does suck air in. j/k . yeah i know it was a lame joke

 

I know the CX does not have VTEC, but it is a 92 and it is pre wired correct? That should make it easier. What makes the D15B manifold not work??

i can run outside and take pictoral evidence that a d15B manifold will, infact work. i dont know WHO is spewing BS to you that it wont, it will and be 99999^9999 times better then the CX one

 

I've owned both a d15b8 and a jdm d15b. that intake manifold seriously sucks *******, just throw the engine in w/the JDM IM like Bense says. I did the same exact thing and mine's been running great for a year and a half

I thought it would too but I never swapped a D15B mani in a CX so I wouldn't know for sure .

PS:
That's a really high number .

EDIT:
LOL.

I went to type that number into my calc to see what it actually was (TI-89) and it spat back the infinity symbol. :-P. I didn't even know my calculator could produce the infinity symbol, I thought it would just give me a number in scientific notation, oh well, even though I doubt it's infinity times better (as that would make it perfect), is it really that much better?

Like I figured the D15B IM would be a lot better than CX mani but I never did it so I wouldn't know. But like..I wouldn't expect to see any gains from it. Maybe a bit better feeling or soemthing, but that's all. How much gain do you honestly say you got from it? I'm surprised it's that much (or that the CX is that restrictive).

EDIT2:
PM me or something, Sorry @ OP, I'm not meaning to threadjack

 

cx does not require any modification

I have a cx manifold on my jdm d15b at the moment actually.

I would highly recommend NOT wasting ur time.
Just do it right the first time or don't do it at all.

also the cx injectors are smaller than d15b injectors, so don't use those.

basically the cx everything is SUPER restricted, the throttlebody, intake mani, intake, exhaust mani, exhaust, injectors, ecu, ALL that stuff is built for a 70hp engine, not a 130hp..

I should also note that i'm running the cx injectors/ecu on my d15b, and gas mileage isn't even all that great

What does that make at the wheels? :-P

I know somebody had to dyno a stock CX O.o

 

Ok will use D15B one thanks and sorry for confusion...what does a CX make at the wheels...?? LOL

 

hehe, no idea,
it's probably not that low though,
when my car was stock I was driving it around, and it sure felt like more than 70hp,

though the d15b felt like mor than 130hp so i dunno.. hehe cx hatchies are light

 

im sure the CX fuel injectors are the same as almost all d-series size(the d16y7- civic dx injectors are the smaller 190 compared to 240).

the gains you get from the manifold will be in the air you recieve and not the fuel( due to injector size) and will be alot better. if i remember right i had to T off a hose and thats all to modify the jdm mani to run with my P28

 

I've always heard that the CX injectors are 190CC also. If you look up the part numbers for CX/VX they are the same while the EX/SI are a different part number. So I am assuming they have some differences.

 

yes the manifold will work although the best d-series manifold to use would be the d16y8 manifold
