Full-Race-style turboheader for A20 is born!!!

It's made by the user "silly sohc" on Honda-Tech. I'm sorry to say that I don't know anything about it, I have just learned about it. I have sent him an instant message where I asked him to market it here on 3Geez. I also don't know how much it will cost, but I'm GUESSING $600. Here is a Link to his user profile on Honda-Tech.

Good find :D

I was going to make a manifold with that same design, but now it seems it's not an original... it's okay though, I'll probably do something similar to the civic manifold he made... but have the tubes come off #4 and #3 and make the turbo flange centered between them and face down, then just extend tubes form #2 and #1 to meet the flange. The wategate will be centered between #4 and #3 but be on top, maybe angled towards the radiator some... :D

If he PM's you back let us know... his work is good so it will certainly put me out of buisness if he does decide to make them. :sadwave:

Damn that guy turbo's everything... lol :D

Then where you gonna put the wastegate? The intake? :nuts:

j/k :)


Looks real good!

that guy lives 6 hours from me

Very nice. I might have to get me one when I am ready.

Check out this thread. Lot's of good information.

Realy like this design for a couple important reasons.
1. Longer runners for better low end torque.
2. Brings the turbo to a higher mounting point (oil drainage, clearing A/C)

Problem I see though would be spark plug access?

I figure around 18, 90deg. elbows from McMaster-Carr at $5.30ea. = $95.40, collector from that dude (B18C1CYA) at $75 shipped, and flange from BMC for $30, the parts total should be around $250 (including T3 flange). Now, can anyone build one for around $150 labor to make it a $400 manifold :)?

LOL, I was tired you know what I ment. :D

i've heard that that guy at BMC takes F O R E V E R to make those flanges. He's some kid taking a shop class and uses his dad's CNC machine or something.

and that guy with that cardomain is CRAZY. i wanna be his friend! :lol:

Ditto NXRacer... Ive heard alot of people on the net whining about them being slow. I finished my 4-1 turbo mani made from sched 40 mild steel and i think itll flow very good... hopefully almost as good as seans, and the welds are strong and have good penetration but are a little on the fat side, and it is braced. Its 1.5" diameter tubing and it was a pretty big pain in the ass to fabricate but it looks like its gonna fit but be close. All the research ive seen seems to indicate that runner volume and collector flow play some of the biggest roles in making efficient power in the exhaust mani, and not soo much runner length per se... thats why log designs suck unless youre on a budget or are gonna upgrade later or dont care... a tubular design is much more efficient. Damn i need to get pics of it

yeah you do!

What's with the cold responses? I really expected people to go temporary insane and carry torches, hold rallies, loot the town and shoot their guns in the air.

Coming back to the topic at hand, I'm sure this manifold will give greater gains than the POS Pacesetter when used on a N/A engine. Those relativily short primaries would probably give crazy top-end power.

Anybody e-mailed him for more info yet? I didn't, just IM'ed him on H-T.

:nuts: you cant use that manifold on a N/A motor!

yes u can... just put a down pipe where the turbo is supposed to go...

That thing loooks like a ram's horns! Thats a good find though.

our header had zero drain issues good spark plug acess etc etc etc and works with all the stock running gear minus the fans. while that header looks really nice. i doubt that you could even run a stock radiator with it. nice peice. ill talk to the fab shop and see if they can do anything in the future with making ours equal length. moe changes updates etc.

hey all,

PM's replied, thanks for the feed back..... signed up last night late. :)

Hey, welcome

I used your pics in the TURBO FAQ
https://www.3geez.com/showthread.php?t=37169
Hope you don't mind... oh I brightened them up a bit too. :D

np :)

I noticed that some of you were wondering about the ps and spark plug positioning.... I was able to keep ps with the mani and still have room for the plugs to run.... I would recommend keeping them close to the valve cover. however, I did have to put a slight bend in the oil check stick so that it didn't interfear w/ the #1 runner.

oops double post

silly sohc


So what made you make a nice turbo manifold for the old a20?

Do you have one yourself or did you make it for somebody else, and what other mods go along with this manifold?

Did you see what he use's for manigmant on his civic at 15lb's of boost.

What is all done to the civic motor? I run a similer setup. There are some people here that say a FMU is a ghetto setup.But these people have NO expeirence with turbo.I have the same FMU as you and a MSD boost reatard and FPR and bigger pump.

Thats adequate for lower boost... i think 12psi is ALOT to ask of stock injectors though
