manifolds which one is the best

[white20gfwd]

i was tring to find the best manifold for all out performance. i have a ported 2nd gen now but i was planing on going with a hks or a turbonetics manifold. any suguestions on what one is better than the other one, who uses used any of them. just some info would be great.

ported 2g manifold has gone 10's. stay with that and invest elsewhere.

They have the good stuff. The stock 2G manifold is good, and if ported works really well. If you do upgrade, go with DNP.

 

[white20gfwd]

wow holly sh!t. they are very nice. shiney new parts are good, you should hook me up.

Stick with ported 2G.

People on this board honestly love to throw money away .

 

[white20gfwd]

money is no object when you want to go fast. sometimes you just have to pay. and i wasnt looking for the most costly item. i just want to know what the best one is and why.

 

[eclipsegsx9797]

wow i never seen them manifolds before and they are realy nice, i almost wanna sell my sfp for one.

IMO i don't think you need anything bigger then a heavily ported 2g mani unless you plan on pushing over 600HP. IMO i think the exhaust gasses should be taken as close as possible from the engine and into the turbo. I don't see how a big tubular mani will gain anything unless your making some serious HP. Your taking them hot gases(witch as you know hot gasses's move easily/freely) looping them around these large diameter tubes the gases will lose TEMP and speed then you bottle neck them into your turbine housing, i don't see how this helps?

i think its best just to run it through the smaller diameter holes as the air will travel at a higher speed and be dumped right into the turbo nice and hot on extremely HP car through i can see were a tubular exhaust would be and advantage because of the extremely high air flow.

basically I think the air is going to travel hotter and faster through a 2g mani and as long as your mani is the same size as your exhaust ports in your head your not gaining anything tubular.

Slower traveling gasses in your turbine housing = more lag.

Unless it's just something someone _claimed_ would help you go fast.

WOW that sounds good but have you tried both.....? Didnt think so.

My DNP spools almost 500 rpms sooner then the next person using the same turbo.

ported 2g manifold has gone 10's. stay with that and invest elsewhere.

14b's have gone 11's

20G's have gone 10's

and people have made 500hp on the stock head intake and cams.

maybe we should just get a 16g and down pipe because thats all you need to go fast, and invest our money elsewhere

 

[dsmstunna]

just wondering what is the size of the headers on you your DNP mani?

2G manifold is fine if you want to be stuck running a mitsu flange style turbo. I want to be able to buy cheaper turbonetics/garrett style turbos. And now with all the new really cool Garrett GT style turbos (GT 35RS and GT30R etc) which are all T3 flange you just can't run a stock 2G manifold with one of those.

I bought a turbonetics manifold and ported the crap out of it. Not as nice as a shiny tubular header but also a lot less crack prone (I can hear the yelling starting already). To each their own but thats my setup.

youre stating out of the ordianry cases. im giving a general statment that has been proven by many people, many times. nice try though.

*Many* 10 second cars use full Garrett setups. which usually does not include a ported 2G manifold. A 2G manifold will work and CAN put a car in the tens. However I believe the question was what is the BEST performing manifold. Maybe you should do some more research on how and why equal length tubular exhaust headers effects power production. There is nothing GENERAL about a car that runs 10's. I believe you have been misinformed.

nice try though.

JDMAWD,

Not to hijack this post, but it looks like from your sig pic you made a trip to a Dyno. What kind of power did you put down?

he isnt going to be running 10 sec times anytime soon. a ported 2g manifold is perfect for him. bang for buck can be found elsewhere.

Then why bring it up? Anything that will aid spool up and flow more up top. in my opinion is helpful and worthwhile. Have you actually had both on your car, to make an intelligent comparison on drivability and spool? or are you just regurgitating unfounded hearsay.

 

[dsmturboawd]

i brought it up to get my point across: a ported 2g manifold will be more than enough for his 20g. thats all i was saying. i was giving my opinion that he should spend money elsewhere, just like you gave your opinion. that is all.

No you gave an opinion I gave feed back from my *first hand* experience using both types of manifolds being discussed. He didnt ask what would be *good enough*. He asked what would be best. A equal lenght tubular header would be best. I believe this was his original question was it not?
