any see a problem with this? make evo manifold work on honda.
 

ok. so in my "msut have cheap turbo honda" mindset, and many www.homemadeturbo.com threads later i have pieced together a turbo kit for less than 200$

the msot important pieces.

i acquired a evo turbo, manifold, wg, o2 housing.

the turbo is twin scroll (meaning that two exhaust ports go to one side of turbo, and two to the other, to make equal exhaust pulses and some other bs (better/ equal/faster spool)

i want to use the twin scroll system

here is my FIRST IDEA
take a stock honda d series manifold , and chop off the flange (ports for head) and ghetto weld to evo manifold ( i understand theat the arent the same length ect, but i had fixes for that).
PROBLEM:
manifolds are CAST IRON and it is very hard to weld, nad even harder to get right without cracking.

WHAT I PLAN TO DO NOW:
buy a honda flange (like a shop would buy to make a turbo manifold) and also buy an evo one.
weld small pipes from the honda ports, to the evo ports, then bolt evo flange to evo manifold, and honda flange to head on car. the pipes wouldnt be more than an inch and a half long, but i have ample room in my enginge bay so its no problem anyway.
of course i will have the flanges bolted to heads as i weld the pipes to each one (to prevent warping from the heat)
the only problem i come up with so far is to make sure i have a bracket holding the manifold up, so there wont be too much pressure on any of the welds onthe small pipes.

any thing i didnt cover please ask, or any potential problems you see.

sounds like more of a hassle than either making or buying a manifold

whats so great about the evo manifold? anything?

Re: any see a problem with this? make evo manifold work on honda.
 

buy a manifold? i have a turbo d manifold.. but would be hard to adapt to a twin scroll turbo ( not even close)
and i dont wnat ot spend all typ of money.. its no hassle its an hour of welding/ cutting pipes)

the evo manifold is split into two separate parts. each time exhaust gasses are emitted (two outside, then two inside) they o through different ports to turbo . so if i use another manifold i wont be able to utilize the full potential of the turbo for what it was made for.

Re: any see a problem with this? make evo manifold work on honda.
 

yeah just get some flanges and make a mani. how do you know it will even fit in the engine bay once you get it ------ rigged up?

Re: any see a problem with this? make evo manifold work on honda.
 

explain to me why i would spend mony on a manifold vs 40$ in flanges?

and tell me where i get the d series manifold for a twin scroll turbo.

then go back to my 40$ solution.

and i posted already that i had ample room in the engine bay. the pipes wont be 4 ft long. it will fit. i will have extra room

dont want to run a manifold str8 to this, seems as if it may make the flow of air (not as smooth) as if i used the evo manifold, witch is divided exactly like this

Re: any see a problem with this? make evo manifold work on honda.
 

well then just do it and if it works let everyone know. what are you looking for by creating this thread?

Re: any see a problem with this? make evo manifold work on honda.
 

i am lookign for what the thread states, if anyone sees any potential problem with it, or a reason it shouldnt work.

so far all i have gotten is alternate routes ppl think i should take. i dont wnat to spend the money that the ideas posted require this is hmt......

Re: any see a problem with this? make evo manifold work on honda.
 

problems:
-chassis fitment
-ass pain
-why?

solutions:
just do it
or
take the advice given
and make a new mani

Re: any see a problem with this? make evo manifold work on honda.
 

i guess we jsut see it different. i stated chassis fitment wasnt a problem, why? cheap and simple, not pia.

i got the ball rolling on ordering my flanges so ill keep it updated.

but like u siad, better to do it than talk so ima get to it.

Re: any see a problem with this? make evo manifold work on honda.
 

Dude, here's what I would do. I would first cut the middle bridge of the turbo gasket where the split is. Then I would knife-edge the split so gases would go into both sides. It might not be the most efficient thing ever, but it beats the snot out of whatever half-assed thing you're plotting on.

Re: any see a problem with this? make evo manifold work on honda.
 

i thought about that, and i may end up doing that, but i am going to try this first.

yeah so did my other turhttp://img134.imageshack.us/img134/2613/1001046sm9.jpg
bo d, but is that turbo twin scroll? if not no wonder it was easy.

turbo d is easy, trying to do it a lil differnt this time... old setup

Nice job man ;)

Re: any see a problem with this? make evo manifold work on honda.
 

Pm Eville140 about making you one, he made one for a friend and it is totally PIMP :y!!! Great price/ great guy!!!!!!!!!!!

Re: any see a problem with this? make evo manifold work on honda.
 

LOL it's an evo8 manifold and turbo man. And the engine is an F22

VOUCH RIGHT HERE ON HIS CAR DMC1's car is a stunna

Re: any see a problem with this? make evo manifold work on honda.
 

Twin-scroll 16g6 ftw! FYI, those turbo's are closer to a 20g in size than the older Evo3 type 16g's. Check the hotside and see what's stamped on it and the turbine housing...'03-'04 Evo's are a 9.8cm^2 hotside with a funky twin flapper wastegate design. The 10.5cm^2 housing is usually only a single flapper.

Re: any see a problem with this? make evo manifold work on honda.
 

Here's a better idea.

Things needed:

Band saw
D series flange

Run the Evo 8 manifold through the band saw cutting the head flange off of the cast as close to the head flange as possible. Then get the d-series flange and weld it on with a mig welder. Finish it by porting it all out. The thicker the D-series flange is the better, because you'll be able to port the flange and make the transition a little more smooth.

At least that's what I would try to do if the ports are anything close to on another.

Intercooler that aren't covered up all the way by the bumper make me angry...

Re: any see a problem with this? make evo manifold work on honda.
 

That's not really feasible to do either. The stock 4g63t manifold is almost a perfect fit for a F-series (as the pic above shows), which means it's going to be off by quite a bit on a d-series. Once you go about 2 inches in on the manifold runners, it becomes basically one solid cast piece, and the runners come in pretty straight for those 2 inches or so as well. Even his original idea of building an adapter runner section is going to be a PITA with the angles the runners are going to need to match up, not to mention the much larger 4g63 port size. If nothing else it would help prevent reversion though lol.

Re: any see a problem with this? make evo manifold work on honda.
 

getting in to see how this goes. i have a feeling we will either never hear anything again or laugh and say i told you so

Re: any see a problem with this? make evo manifold work on honda.
 

Yeah I figured the spacing wouldn't work out. I thought it might be feasable if you cut it farther up the manifold but I guess not. Oh well

Re: any see a problem with this? make evo manifold work on honda.
 

if you need a cheap manifold just weld up a pipe fitting log, order a flange from wiertech, and weld away. Done for like 50 bucks

Re: any see a problem with this? make evo manifold work on honda.
 

Normally you could, but the twin-scroll flange makes things a real bitch for a log. On the 4g63 they pair the cylinders as 1&4, 2&3 into the flange. If you have the ability to do some tubing work and welding there really isn't any reason you couldn't make one like this with the proper D-series head flange... http://forums.evolutionm.net/showthread.php?t=154319

Re: any see a problem with this? make evo manifold work on honda.
 

look at this
http://cgi.ebay.co.uk/HKS-Exhaust-Ma...ayphotohosting

thats a hks manifold and what they have done is pair runners 1 and 4 into one hole and the 2and 3 into the other, Am i being thick but coudl you not design a simialr manifold in that fashion where the runners go to the same place? Buy the had d series flange and the evo turbo side flange and get fabricating. Im sure the end result will be better then making a manifold adaptor which to me sound much harder then makign the manifold like i suggest? Or am i just being dumb cause i don;t see a problem with my plan and basically what the previous poster has said as the piping isnt that complicated.

Re: any see a problem with this? make evo manifold work on honda.
 

Umm yeah...that's pretty much what I posted 1 post above yours. :l Reading owns you. :P

Re: any see a problem with this? make evo manifold work on honda.
 

I have an idea how about sell the evo mani on ebay since they go for a pretty good amount to dsm guys I mean 2g mani's sell for atleast $60 and I think you could get atleast $100 out of a evo mani, than use that money to buy the materials to build your own mani

Re: any see a problem with this? make evo manifold work on honda.
 

They don't sell that high. I see these things on ebay and other Evo forums, usually around $40-$50 all day long. They're kinda hard to get rid of by themselves.

Re: any see a problem with this? make evo manifold work on honda.
 

why dont you just make an adapter plate? :1
