Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Just some fab work I did over the last week, I spent 4 days (8-10 hours each day) on this single manifold in coming up with the design and building it

This customer is shooting for 1000hp but is worried the gt42r will restrict him so when he maxxes this turbo out the is going over to gt47r ;)

maybe its the4 camera, but that flange looks way wapred

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Ok as to flange being warped...

Yes it is but check this
tubular manifolds can have flanges warped and it not be much of a deal why?

Well because the runners are so long they have alot of flex in them
I put this on the head and yes it was warped by about 3/16 " on each end but when ever u put a nut on the studd and start tightneing it pulls flat very easily
I have been building manifolds for 3 years and on every singal tubular manifold I have sent them to the customer with the head flange like that and zero customers have had any problem
I might accosinally get one that is paranoid call me and say it was but what I tell them
" bolt it on the head and tighten it down just as it is supposed to be, if you have a leaking issue (about 1 in every 100 manifolds actually leak) then get a $20 mr gasket 1/8" thick copper gasket and I gaurantee it will be perfect"

Now check this

I have milled several manifolds flat in the past but there is still the internal stress of the manifold, by the time the manifold has been deliverd (shipping is usually 3-5 days) the flange will be warped again because of the manifold's internal stress so what is the point of flattening?

On manifolds such as logs and short manifolds this will not work because they are so small and compact that they have no flex to them at all, but on every tubular I build (top mounts, ramhorns, min ram, etc) they all pull flat when put on the head as a final resort if they dont pull perfectly flat is I cut slots on the back of the heade flange (not all the way through like full race because then the internal stress of the manifold makes the pieces move by like 1/8" and you have to ghetto oversize allt he bolt holes and then you have poor primary alignment on the head) but cut so that there is aprox 1/16" thickness left this allows it too tighten up on the head extremely easily (even log manifolds will flatten out on the head if you do this trick) it takes about 5 mins to cut these slots as opposed to 30 mins to an hour to mill it flat and it will still warp by the time the customer recieves it.

Anyone that actually builds manifolds already knows all this that I sasy though it is just the customers that dont know how it really works lol

my heart lies with 6-1 collectors... looks great man, keep up the good work

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

about 40 hours? :o , nice work!

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

if you cut the collector pipes at 60 degrese you would have a single merge point.

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Yah if I was building an all motor header and wanted a round collector I would do that but with the way we did it here it perfectly matches the t4 flange

WOW James, very nice - I likey very much!! Keep up the great work!

Nice work, James!!

If you ever get out this way, you're gonna have to stop by and show me a few things. ;D

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

I will deffently keep that as a compliment coming from you
I guess I am doing something right first time you didnt critize my work ;)

lol thanks for all the compliments

Looks tits :6 Any more pics or details on what this is going in?Im assuming a Skyline but maybe 240?

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Hey james, manifold looks good man and the positioning is nice to. About your comment above... i was just curious, do your head flanges use factory size bolt holes? If so, how do you get it to slide on the studs if it is warped? Or are you just using bolts and letting it flatten out slowly 1 bolt as a time as you work your way to the sides?

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

What chassis is that in?

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

damn James, that is sweet :o

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

My dad makes the flanges you would have to get one or talk to him to know how he does it ;)

I do not use bolts and the warped manifolds always slide onto the studs,

dual wastegates??

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Yep dual tial 44mm wg
He is gonna be running 40+ psi

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

How the hell did you get to half the welds around the collector?

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

skills and/or a small torch :P

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

I like the collector. How long did it take you to fab that sucker?

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Don't take it badly if I do. I know how particular you are with your abilities and how you like to improve so I try to offer help, even if it's nitpicky stuff. The best welders are like that...rarely satisfied with their own work. For the most part, experience will be your best teacher at this point.

I think you'll do great...and put at least a scare into a few of the places that are making manifolds now.

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

james i wish you could build me a girlfriend because she would be the perfect woman ;) That is rediculous gangster

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

hahahaha good ----

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Its cool man I appreciate all your critisms as they have helped me lots
yah you hit that one 100% on the head I am never happy with my welds lol cause the second I lay now a good one I have one better come out lol I am always striving to get "perfection" even though I know I wont achieve it (what can I say I consider myself a perfectionists lol)

Yah I have only been doing this tig welding for close to 3 years now and have full plans on continuing for quite some time ;)
I am almost 100% caught up with all my orders (got 3 more to ship and am fully caught up) I am not accepting any more
orders (all items will be in stock middle to end of next month) as I am tired of being behind I will not sell something unless it is ready to ship
It has taken nearly 3 years to get caught up and I am not going to get behind again
I will have some nice low budget manifolds for the diy'rs and maybe even some precut kits

-James

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

precut kits sounds like a good idea :y

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

I would buy a precut kit in a second.

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

I know you get my reccomendation when somebody wants a nice manifold at a reasonable price.

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Note the precut kits wont be 100% perfect fit, final fitting will be necessary (a little grinding to make things perfect and beveling will be the customers jobs) but you wont need a saw for anything just little touch up here and there or be gangsta and rember that gaps are not bad as long as you purge (they are just extra ensurance that you get 100% penetration ;) I can weld a .25" gap on sch 10 if I need to and do quite frequently as long as you purge no one will ever know the difference)

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

^^^ i've actually never heared that before. i'll keep that in the back of my mind, might actually help me alot. good tip!

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

diameter?

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Nice work man!

We need manifolds here.
SSAC makes way to much $$ in Japan.

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

thats badass..along with that motor..i will someday have a rb26 in my 280z :y..but for mow i have my honda...anyway awsome work keep it up :6

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

too bad your a faggot and your dad is a ------.

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

THat ---- is beautiful. Good job ;)

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

those are sexy welds I wish i could weld like that

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

Long tungsten stick out and crank the flow meter up to keep out the prosity

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

I missed where the guy asked if anyone had seen tighter joints in their time. I just saw him ask how JG got into the tight areas he experienced on this particular manifold.

Re: Check out this manifold I built! RB26 Stye baby ;) hell no 56k
 

beutifull. nice work.
