i own a 91 hatch with a b16...but it seems that my 4-2-1 already has two MEAN dents in it and sits super close to my radiator...and the space between the radiator and block is not much...so who makes a good 4-1 header that will clear...thanks

 

get an aftermarket front crossmember, run a jdm 4-1, good bang for the buck.

 

i dont want something cheap..im lookin to spend like 5 or 6 hundred on it.....i want a sick one

 

do not get the jdm 4-1 that thing will be super low.
the only good clearance on a ef is the 4-2-1 style. spark racign loks like it will be pretty good clearance wise. since it doesnt stick out farther than the oil pan.

 

clearance shouldnt be that much of a problem...my car is not slammed...what did u guys ues to notch in the crossmember...i dont want a jdm itr anyways...

 

before getting the z-10 crossmember i had to notch the factory one just use a grinder and take a little bit out until proper clearence if i was going to recomend a header for the money it would definitly be a smsp or a hytec my opinion only though
goodluck

 

i think HAsport made a header specifically to fit the EF

 

theres a crazy lookin header on this board (cant remember the name-someone help me out) that fits the ef without mods. and if price isnt a factor, im sure the big name guys (RMF, SMSP, hytech, yadi yadi ya.....) can make you one. what kind of setup you runnin?

 

if ur talkin about the an-r compact..thats the one im currently interested in...unless i can find something better to fit with no modification thats the one i plan on getting...
my set up is:
1st gen. b16/y1
3 inch short ram
max bore 64 to 62 mm
aebs IM
str fuel rail
b&m fpr
full supertech valvetrain
aem cam gears
sk2s2 cams
dc 4-2-1
si catback
vafc
91 DX hatch
DX is for deluxe

 

its not the an-r, i actually am running the compact on my setup. it looks just like the rmf one though.

 

what about the quality of the an-4 compared to the rmf....i know the compact goes for like 530 new..how much is the rmf??

 

i paid 530 shipped, but i didnt get it coated, now its rusting pretty good. i dont have another header to compare it to, but its pretty nice though, good power, but the bottom pipe didnt line up too good. i had to have a muffler shop bend it-plus it didnt come with a flange.

u realize that i asked for a 4-1 header for an ef...not a 4-2-1 for an eg...

does anybody read anymore

 

Do you mean clear the crossmember or gound ? If your worried about the cross member, all I can say is your probably gonna have to cut it.

Anyway you look at it, if you want a nice header that is gonna perform well, your gonna have to cut the crossmember. Check out an-r

 

yeah the an-r compact is the one im probably gonna get...i was just seeing what else is out there....doesnt the compact fit in the ef without notching the crossmember

Not sure, ask in the all motor forum maybe.

 

I believe that the Hookups header is designed for EF.

RMF narrow design header has good ground clearance. Just like stock. I'll take some pictures if i have time today.

I did read but u were complaining about clearance & alot of 4-1's have no ground clearance & will not really clear the cross member without cutting! FYI that header does not only fit an eg!!! does a dc just fit a del sol NO! so for u. I could have been a dick & just told u to search but I was trying to help because the spark header had already been tested on a B16

yeah, thats the header i was talkin about....supposedly fits in a EF with no modification.

 

well if it is well designed yes it will perform better not all 4-1 are the same & not all 4-2-1 are the same look at what the spark header made over the kamikaze
kamikaze 4-1 vs spark 4-2-1 made 21 hp more
erick's racing 4-1 vs spark 4-2-1 made 10 hp more

 

My Header Tech(Enzo Racing) header fit perfetly in my 90 hatch. The only thing I had to remove on the cross member was the front mount.

 

im not really tryin to remove my front mount....it looks like im either gonna go with the sparks or an-r compact...does anyone know if the sparks will fit with a full radiator on an ef???
