I've been looking at headers because in a few weeks ill be in the market for some mods. i came across this on ebay - http://www.ebay.com/itm/BISIMOTO-STY...ht_1683wt_1095

what do you think about this design? out of this, DC 4-2-1, and DC 4-1 .. which will i get the most power from on a stock d16z6? its has 166k miles on it so im not sure about 4-1 as i would rather not bring the RPM's too high because its aging and i wanna be easy on it to avoid damaging my engine...

You really wanna spend $370 to get an extra couple horsepower?

i need a header anyway since the one i have is rusted to ****... what else would you recommend?

jbpnoman

You're looking at bolt ons for an already slow motor. If you're just trying to replace a damaged part, get a cheap header made for your motor/car.

but when i do some porting in the future wont a header/intake/exhaust help achieve optimal power?? i just bought the car a few weeks ago and ive done an oil change, performance radiator and put new axles on it, replaced the fuel filter, just basic maintenance that it needed, and i have an intake on the way that i got off ebay. now that i have all of the important **** done, i plan on making as much power as possible without boosting it. there are lots of mods i plan on doing, but only one at a time as im not rich lol.. so, which header would you recommend?

jbpnoman

The cheapest one that fits. You haven't done the porting yet, so there's no reason to waste the money on a high dollar exhaust.

D16 Power without boost. You'll have to dump at least ten grand into the motor, and even then a properly built, stock bottom end, boosted D16 will eat you.

Don't do an n/a single cam. Boost it.

My Ebay header fit perfectly and has a nice finish, cleaned up ports and made as much power as a DC 4-2-1.

Ebay headers are said to crack quickly, just like crappy ebay coils....

Mine has been on the car for over 2 years now and is daily driven. No issues at all and no dents, even the cheap ceramic coating is holding up. Granted my car is not slammed and my header does not hot the ground.

Just get the ebay header its cost effective and will do the job until u eventually boost it and have to get a new exhaust manifold anyways

Dont buy the ebay one. if you read it closer, you can see it says "BISIMOTO STYLE Power Driven D-series Headers". This means that its the "Style" of "BISIMOTO", not the actual one which is made by Bisimoto. Basically, this is a replica of "BISIMOTO". It does look the same, but definitely will not work the same. Your basically paying for the looks of headers.

4-2-1 headers is for low-ends. these headers were made to work at its best at lower rpm

4-1 headers is for high-ends. these headers were made to work more efficient at higher rpm. Car will lag at lower rpm with 4-1.

Now you pick what you want wich is:
1. Bisimoto style headers to look kool and show off to your friends
2. Your vehicle to pick up faster with 4-2-1
3. Let sohc v-tec do its best with 4-1

Thank you.

Also, I live in Sacramento, CA and been to their store already. everything they sell is replicas. replica meaning parts they sell is made in China or Taiwan. And alot of JDM kids goes there with their mom's credit card.

That's a lot of valid information, but at the end of the day, OP doesn't need any "style" of header. S/he only needs a basic, generic, 4/2/1 eBay special, to the tune of like, $60. Hell, if the OP had a B series, I've got a header sitting next to me that I'd probably ship to him/her for $10+shipping.

Exactly...if it were my car I would just grab an OEM manifold from a junkyard for next to nothing. The OEM design is already 4-2-1, so there's very little power to be gained.

OP, right now you are probably making 100-110 whp. If you want to make more than 130-140, you're going to want to save up for a motor swap or turbo build. In the meantime, get a short ram intake. They're under 50 bucks for an ebay special and add a nice throaty noise under throttle.

This is just my opinion but a lot of these guys are right, if you dont want to boost and still wanna make a little more power youre pissing in the wind with that z6. If you plan on going n/a then youre 1st step should be throwing a b18 at it, vtec or not and it will be a LOT more fun to drive. You can usually find a smashed in the rear integra with the whole dropout for less than 1000. just my two cents. good luck either way

unreality6794

alright then. maybe i should leave it alone and save for a turbo kit? how are those $1k ebay turbo kits? are they decent enough for someone on a budget? (I make $11/hour). also, how hard are they to install? could i do it myself? I have the basic car maintenance down, i do my own oil changes, cooling system flushes, fuel filter replacing, simple **** like that. and would my old engine with 166k miles on it be able to handle the stress that a turbo might put on it??

what do you think about this? http://www.ebay.com/itm/Honda-Civic-...ht_5152wt_1139

Again, this is just my opinion. I say to hell with turbos. unless you have more than one car. with the miles your motor has i dont think a turbo is a good idea. Also, if you drove an ls swapped eg, you would be sold. if you can find an ls with a b16 transmission, you have a 30+ mpg car that will run mid 14s in the 1/4 mile. that to me is a super cool car. again, this is just my two cents. I just hate watching people put turbos on their stock motors cause their friend said "a stock z6 can hold 10psi". I love that statement. I hear that **** all the time. EVERY turbo setup I have ever seen has destroyed the motor at one point in time. I know its all in the tune too but around here thats $150 an hour for dyno time. I still say throw an ls or b20 or gsr at that car and have fun getting good mileage.

JuggerNaut-CTR

You can buy that kit, but its highly suggested to get a different turbo, wastegate and bov as those parts in ebay kits are known to failure. I would just look for a complete used kit that already has quailty parts.

JuggerNaut-CTR

Have you done a compression/leakdown test on the motor to even see if its healty enough to be able to withstand boost?

unreality6794

I'd really like to avoid a swap unless i really need to.. would an engine rebuilt kit get my engine to where it needs to be the handle about 12psi?

unreality6794

nope not yet, but if it turns out that it isnt in good enough condition, couldnt i just replace some parts and be good to go?

b20c5eg

dont be scared to swap it man. find a 94 or 95 integra 5 speed and everything will be plug and play. Might have to modify the exhaust but EVERYTHING else is plug and play. If you want to rebuild your current motor youre going to spend a lot more $$ and time than you have to, plus the turbo kit plus tune. just trying to help. It would be a lot different if this was a second car but I'm assuming its your daily driver right now

unreality6794

what engine is in a 95 integra? b16? are all the motor mounts the same? all i would need is the engine and the ECU?
