a customer wanted me to jig a set of headers that he had for a 1uz (sc400), so below is what came out. the "crappy" manifold is not my work. pain in the *** getting some 1.75" id pipe with a .120 wall on it, but i found it. either way, the design isn't the best, but i'm supposed to get a car here in the next couple weeks so i can maybe try to re-design them.

my full time welder, danny did about 90% of the welding on this one. turned out great.

we backpurged the crap out of it and it still got some sugaring, but hey no-ones perfect. i'll post up the other side tomarrow.

 

You always seem to put out some nice stuff

 

Looking good man...still up in the air about the big welds tho...

 

I am still new to welding, what is back purging? And can you do this with a MIG as well?

 

you should put a couple of v-band exhaust housing turbo's on the end

there is an up-pipe after the v-bands. two piece design.

i didn't weld the manifold. i had about 4 inches of weld on the one pictured. big or small, depends on what it is.

filling the inside of the manifold with a shielding gas so the weld on the inside does not mix with air to contaminate it and weaken it. . . .

 

Cool looks like they were design for fitment and packaging you gonna post pictures in car too ?

well, i still have yet to take pictures of the other side. i had to build two cat-back exhausts today, so our purge bottle was being used. i left the shop at about 9 and danny (right hand man) was welding it up. the other side looks more like a tubular manifold.

we had no part of the design of the manifolds. i was given a set and told to replicate them. in addition to copying them i also had to go with bigger primaries, thicker gauge pipe, better welding, back purging and keep the flange straight.

the set we built off had over an 1/8" warp on either side of the flange.

we are supposed to get the car these are going on in the next couple weeks and building the turbo kit as well, however i don't get excited about any projects until the customer actually drops off the car.

 

saw the thicker gauge manifolds, they look sick

Hey thats our idea

Our next shop project car is soon to be underway. SC400 1UZ-TT using Tial vband inlet 35r's. Hoping to crack 1000whp on a mildly built motor. We haven't come up with any serious thought on the manifold design but they will look a lot different then the op's, hopefully an equal length design if space allows

 

i havnt gotten to look at an SC400 engine bay, i'd like to though.

i have 2 SC300's here right now. 1 has a 1j in it and the other 1j should be here middle of the week for the other. hope to do a 2j next.

im starting to like these cars a lot, which scares me lol

 

Thats all we do anymore. We like them A LOT! We currently broke the NA-T stock motor record with making 700.1 to the tire on a $350 165,000 mile longblock from the junkyard. Headgasket and studs along with our intake manifold we make......and of course fuel and ems, GT4076R on a hair over 30psi.

And another that gave us all a scare lol
http://www.youtube.com/watch?v=yevUEmermdA

We're currently working on an SC300 that will be a drag car, shipped to us all the way from San Diego Looking to start off with a mid 9 on the current 74mm turbo through a TH400 powered by a Titan built GTE 3.0L and full street trim. After that a GT45 or GT47 will be going on If anyone here is going to Texas2K8 we'll be there with it this year, should be done by then and hopefully get some track time before the meet.

 

just throw a 91mm on there lol should make nearly 1400 on boost alone.

im excited to start messing with these things more.

 

Well they say after you want to make 800 your gonna want to throw in some ARP rod bolts. So then the motor wouldn't be stock anymore

 

Better to do it now before something breaks.

the uzfe v8 are more on the lean side then the Nissan Vh's.

these manifolds are for a customer running twin s372's. with basically a race motor in it.

first pic is both sides finished. the ones that follow are comparisons between the original design and what we came up with. this is the first set that we've made and i'm already to switch a couple things within these constraints.

there is definatly room for improvement, but these will do the job for now.

 

here is motor:



here is mod list:

"He's planning on running twin BW S372's (72mm), and word on the street is that at ~26psi, the motor [may be] capable of ~1500rwhp. The already beefy mains are reinforced with 1/2" 4140 straps, the cams are 10mm lift w/ a 230 @ .050 duration. The crank is made from HARDEND schedule 9310 NiCrMo, and the buckets are shim under and also CrMo. Teh bearings are ACL coarted by Calico. Beefy. Basically a race motor taken to the steet.

Thats the member on Supra forums 4.7L his engine is.

that may actually be eric's personal engine, but never the less, the other one is the exact same.

 

I was just reading the thread over on Club Lexus about these manifolds. PRICEY But non the less good work, and I know its tight as hell in there. We're gonna attempt some type of equal length setup, but to be honest we haven't started on it at all and we know its going to be very difficult.
As far as the build on ours. Bottom end will consist of forged rods/pistons, stock crank, and probably stock main caps unless we get in there and don't like what we see----have'nt opened the motor yet. Also we will be doing a custom intake similiar to our 2JZGE, but 2 of them with 2 wilson 75mm throttle bodies. Each turbo will feed each bank seperately!

Sorry for getting OT. Awesome work on those manifolds and keep at it!!!!

 

Equal length ? In that bay hahah have fun it'll probably remind me of the Supra with the crazy *** piping - sequential turbo setup.


S13 & Nissan V8

the pricing is all him. he makes good mark up. i'm going to try an equal length setup as well. i just have to get a car here first. if you start building, post it up, i would be interested to see what you come up with.

if you need any specialty engine parts or anything, i can get you in touch with eric. he does all the engine stuff himself. lots of wierd custom one off parts.

 

We'll be sure to document the entire build for the car. Its bone stock at this time, so we have A LOT of work to do.
And we've already been talking to Eric. Probably going to use his V160 adapter for it

sounds good. keep us posted. i'll probably take some pics of the one we are going to build too.
