I'd like to get a 4-1 in there, but I don't know if its possible. I read in another post that someone had the Toda header in thiers, but had to cut the center radiator bracket or something. For the people out there with a setup like in the title, what kind of header are you using, and did you have to make any modifications to anything to make the header fit? Thanks

 

keep searchin noob

 

Just about any header will work but with a 4-1 header, but you are going to have to some small mods.

small mods as in what? are we talking bashing some things and cutting some brackets, or a smaller radiator?

 

bashing, cutting. but not a lot

 

This should probably go into tech right about now, but whats the best bang for the buck 4-1 header for the B16? Somewhere around 400 or less?

 

some say DC. but maybe even a JDM ITR 4-1

 

hmm, if the JDM will fit I might just try that. Thanks Bryant, anyone else have input?

 

I have a 4 2 1 dc sports header on mine. Not as much cuting into the cross member is needed when using a 4 2 1. they are better for low end power too

 

well its in a first gen so there isnt alot of room to start with but there is a 4-1 that can fit possible the very very bendy one who makes it uhhhhh someone knows

 

I have a b18c in my rex with a 4-2-1 header. Plenty of room.

 

that would be me. i actually removed the center support and did a little mangling to the radiator fan cage. there is a little section(bout 1/8"-1/4" of space) where the header almost touches the radiator but other than that it fits. any header should work call hasport and confirm it. i think they told me they put in the dc 4-1 which i think is similar in size to the jdm 4-1 and it fit. good luck.

::raises hand:: over here.
yeah hi, question...why do you want a 4-1? cause it's all the rage? cause you want that extra 2-3hp with the benefits of possibly overheating? or do you want even less ground clearance? you want to spend $100 more? i mean c'mon, find me ONE good reason for a 4-1 in <u>THIS</u> situation...

who cares about a [croud oooohs]4-1 header[/croud aaaahs]. just find a deal on a 421. it will serve the same purpose but without all the bullshit to worry about in all the questions above. since this is a street car most likely, you're not ALWAYS gonna be up in the rpm where you would even benefit from the extra 2-3hp anyways. and if it's not a street car, you wouldn't be asking the question. you'd know the answer.

 

www.an-r.com I used to have the header but sold it to pay for bills. Still wish I had it

 

The reason I wanted a 4-1 was because I had always thought the 4-2-1 was better for midrange and torque. With a car as light as a 1st gen CRX, I'm happy with the amount of torque I have. I thought that the 4-1 was better for top end, which is what I was aiming for. I never wanted the 4-1 because it was all the rage, I just thought they were a good performance mod on the B16, especially if you were only looking for the extra ponies up top. Are you saying that for a daily driver car, a 4-2-1 is better performance wise and because you get better ground clearance? Am I right about the 4-2-1 giving you better midrange and torque, while the 4-1 gives you better top end? How can the 4-1 sit lower than the 4-2-1?

 

ahhh i c the other muegn crx owner has joined our board.....IMO a b16 makes power up top anyway why not harness the power get the skid plate for the 4-1 and see how well ur clearance is u dont have to slam ur car like some people....its better for ur car not to be slammed any way.....and if u do lower the car lower it to where ur header is safe.....and good luck

 

go with a comptech header, performance wise its right up their with the 4-1 headers and is probably the best daily driver header out their(performance/quality wise). At most you'll have to bang the front crossmember in a bit, but I even doubt that.

 

what gives you the right to call someone a noob?

mr 12 posts

 

just replace the stock front cross member with the place racing unit and
you can fit any header you want

 

keep in mind everybody this is a first gen crx not an ef body.

thanks for giving me the first opportunity to use this-
over heating? even with the header practically resting on the radiatior my car still operates at a normal temperature with no more than regular fan operation time. i dont even have water wetter in the car like i usually do right now. ground clearance could be an issue i you really have the car slammed and drive like an idiot. the toda header i use has excellent ground clearance (just slightly lower than the oil pan) and if you dont have the money to spend on that i belive that there are some good headers on the market that offer good ground clearance.
uhh he wants to. ( thanks again for that)

 

thank u roger for that some people just like what they like and it is a first gen people dont read the whole post all the time

 

i kept that in mind. actually what i had in mind was my old 87 hatchback with B20vtec and it's header. so what comes out of my mouth on this subject is strictly out of experience.

i was refering to some people's (not mine) idea of replacing the stock radiator with a smaller one to accomodate some useless-ly long 4-1 primaries. with a smaller radiator, it IS possible to have a problem (meaning not all the time) with overheating. so what you said has absolutely nothing to do with what i meant by the "overheating" comment.

so you're admitting you bought a toda header for it's ground clearance?!? or did you buy a toda header for it's stunna-rific value? this is how it is, people buy DC headers because they know DCs work. people buy toda or mugen because it's jdm y0! you paid for the name. can you honestly tell me that you bought the toda (for whatever price) because you saw dyno graphs charting the flow of DC vs. toda? oh what's that...NO. oh so you DID buy it to be a jdm stunna...y0!.

and seriously, what's with the "if you can't afford toda" bullshit. are you trying to sound like a hotshot because you have a toda? well face it bud, you're driving a 1985 C-R-X. you don't sound cool to people when you explain to them that your header cost more than your car. just makes you look like an idiot. and again, i don't care what YOU paid for it, you're commenting as if you paid what toda thinks it's worth.

here's my DC that was on MY 87 Si...

if i had a better pic, i'd show you how much clearance i had with that. THAT header was tight in there. but let me tell you this...NOT ONE TIME was i driving this car, with the DC 421, did i think to myself "**** i should have bought a dope-*** looking 4-1 so that i could have picked up two horsepower at 7500rpm." 421s give plenty of clearance to the radiator, have plenty of ground clearance (not even an issue), make plenty power and work perfectly for what they're designed to do (which is outflow stock exh. manifold), so again...give the hammer to yourself newbie, in your post you never gave me a VALID reason to choose a 4-1 over a 421. you've only proven to me it's for bragging rights (if you want to call it that) and to be a jdm-stlyed stunna y0.

keep in mind, my 87 B20vtec would've eaten your "beast" 85 LSvtec alive...even with my 421! you ain't got ****. fucken newbies.

 

yes, exactly. unless you ALWAYS are in the upper rpm while driving stoplight to stoplight, then yeah, i think you'd notice the EXTRA 2hp the 4-1s supposedly yeild.

yes, theoretically.

instead of 2 pipes running underneath your oilpan/tranny, you have 4. on top of that, 4-1s usually have larger diameter piping. think of it like this...

oo = 4-2-1

OO
OO = 4=1

 

"keep in mind, my 87 B20vtec would've eaten your "beast" 85 LSvtec alive...even with my 421! you ain't got ****. fucken newbies."

you cant say that.. yeh and IF you still had your 87, every driver is different and every setup is different.. so for all you know he could beat you with his ls/vtec..
Hammed, what was your 87 b20 running??

I seen this car pull high 14s on a d16a1 that was 2 years or so ago I though that was a good time(also got it on tape too).. now he has this ls/vtec swap and i'm sure hes possibly 2 secs faster then he was before atleast..

E-Town4229, you dont know me but i saw your car a long time back when it was d16 powered at e-town import vs domestics and thought it was nice..

 

Ham'ed Hatch, I appreciate your strong feelings on the 4-2-1 but I really don't think its at all necessary to give the people who like 4-1 headers crap. I REALLY don't appreciate your comment at all that the header would cost more than the car. I think that was a real stupid remark. If you're going to offer your own opinions on the topic, and leave mine and the others out of it, then please continue to participate. But otherwise, go find yourself another thread because all you're doing here is making yourself look like a jackass.

Like I said before, with a car that weighs about 1700 lbs stock (if you don't beleive me, go here: http://www.autotrader.com/research/m...&ac_afflt=none , I am happy with the amount of torque the engine currently makes. I'm looking for top end power, which a 4-1 header does. I'm not planning on slamming the car, you can only lower the 85 CRX so much.

My next question, does the JDM 4-1 flow better than a DC 4-1? Anyone have dyno charts to prove it?
