Hey guys, Im almost done my build of 2 years and I would like some feedback on a header since you guys will know better than me. I was thinking of doing a weber sidedraft setup but I scrapped the idea. I just got to do the wire tuck, abs delete, drop the motor in and TOON...lol

My setup:

1.8L 11.8 CR Weisco pistons, Eagle rods
Ported head, Skunk2 Intake Manifold
JUN Type 3 cams with full JUN valve train
RDX 410cc Injectors, Skunk2 70mm Throttle body

Header????

I was thinking either the Narrow RMF replica or the Hytech tri-y. All responses are greatly appreciated. Im aiming for 230whp.

And ofcourse the ride:

 

Skunk2 New header - Heard from a good source it was a great header.
RS RMF Drag header
Bisimoto V2
SMSP b19 Header
Real Hytech header

Those would be my recoomandations. The skunk2 would be the least expensive but will have good quality and make good power.

P.s. I am no header guru but I have very knowledgable friends and I do ALOT of research.

 

I dont know what a guru consists of but I have built over 2000 headers in my life.And i will say any of the headers listed above would be a good choice.Just STFA from copy headers.You might think you are getting a deal but you will find out that unless they gave them to you for free you got screwed.I promise you.

 

I might have overheard some private engine dyno testing results, also still waiting on my special "Cal Edition". God bless Randees soul.

 

Ironman glad to see you didnt get banned. By the way I would be running your Drag header but RS kept putting me on hold when I called to place an order so I said the hell with them.

 

OP, think about it you spent serious jack, effort, and time to build that motor and now you are considering a copy header?

Buy a header where the original author put in the R&D.

 

I have spent alot of time on HT. Am I a header guru?

 

ive had a hytech & theres nothing like it. Now i have a kidd racing header "knock off" & i was very shocked for the money of how it is .yes the namebrands will make more power but i dont have the budget for it nomore then i ask myself is 5 more whp worth the 900 more?

 

SMSP ftw
RMF makes a good header to

 

I am new to this all motor thing and the only reason I was thinking of getting the narrow rmf is because I thought they were discontinued like the original toda (correct me if Im wrong on that one being discontinued too...lol) I do know that the Hytech tri-y is readily available.

 

Would the RMF Drag clear a full size rad? It doesnt seem as if it would.

 

+ 1,000,000,000,000,000,000,000,000,000,000,000,000, 000,000

whatever number that is

 

This is probably one of the best statements on H-T in a long time. Having been involved in header designing for many years, our performance never came from copying someones design. But from making our own design and testing. When Hotshot Performance was around, we were hard to beat. That is unless some certain company would pay the magazines to make it look like they were better. I remember one company that I will not mention, won the "header Shootout" because their header made more hp from idle to 1500rpm...... LMAO!

 

Well, been doing alot of research and I think Im more confused now...lol. So there are 1.9L headers and 2.0L headers. Wouldnt a 2.0L header perform just as good or even better on, lets say a 1.8L motor? I know it wouldnt be so, the other way around. Forgive me, Im just trying to grasp the concept here.

 

Lets see we build the following for the B series

B16 a 4-1 and 4-2-1 (however I'll recommend a Toda if you want a 4-2-1)
B18A 4-2-1 for 90-93 cars
B18A 4-2-1 for 94+
B18C1 4-2-1, 3 different stages (can't use the tranny to block braces)
B18C5 4-2-1, 3 different stages (can use the stock ITR tranny to block brace)
B18C 4-1, 3 different stages (honestly don't sell many since the 4-2-1s do better but some people still want them)
B19 4-2-1, 2 stages
B20 4-2-1, 2 stages

Plus any number of side exit pieces.

So about 17 different headers for the B series. But for your build I'd say a B18C1 Stage 3. Yes, you can run a larger header and in some cases make a little more top end but you'll sacrifice some mid range and get a rougher torque curve.

 

I Have been making headers for 35 years.So believe me when I say buy any name header that you have heard here on HT EXECPT A copy header.In a couple months you will be mad because you will need another one.

 

This header stuff reminds me of the old Fram oil filter commercials. "You can pay me now or pay me later". People buy the cheaper dollar ones because ahhhh they are cheaper. They will spend money for good quality pistons, valves, valve springs, rods, ecus and cams but decide they will start "saving money" with the header. Smash it and buy another copy.

To the OP, these statements are made in general context and not at you.

 

Hell Yes

 

With an N/A setup... Every ounce of HP is worth it.. But most people wont figure that out until they lose by that half a car or less... It doesnt sound ike much. But it sure is when either racing for big money or trying to go to the next round...... Dont cheap out.

Replicas are for the people who just want to look cool. But when they get it handed to them , they are usually the first ones with some lame *** excuse as to why they lost.... Been doing this since 1988 guys. I think I know what works and what doesnt...

 

^^^^^ Exactly how I feel.

 

ok guys, tell me this...... if i was on a budget would a dc , megan or kamikaze header be better than a kteller rmf or hytech replica until i could get the money to buy an orignal one? kteller has a one year warranty on their header so for $400 it dont sound too bad for a temporary

 

I don't see why the RMF replica would be a bad choice if you're on a budget (morals aside because that's a never-ending debate).

To the OP: It sounds like you're pretty serious about performance due to your build so you should have the money for the real headers. Can't go wrong with em.

 

heres a little something to look at while you make your choice. chris whitfield did a header test comparing two "knock off" headers to a big name header. read up on this. it might give you a little insight as to what you are looking at...

good luck. to be honest, from personal experience with an all motor 1.8 liter, i had the best results with a HIGHEND 4-2-1 header...costed me $450. now im not saying that a different header would have yielded better results, but i was pretty damn happy with mine. plus, the ground clearance is amazing. it tucks quite nicely against the oil pan and i never get nervous when going over bumps in the road and speed bumps. i made 219 and 146 with this header with 1.8 liters and 11.8:1 compression and a non-ported head..

 

If you think that I am going to say ANYTHING good about some no talent copying POS that is making money from copying all my (RMF) Honda headers ,You have another thing coming.

 

You wouldn't be negative if the payoff was more positive--wink wink broken down negotiations due to a $30 price differential per piece sold.
