At my local scrap metal yard I can get any size sch 10 stainless steel piping for 4$ a pound (Scrap bends and straight pipe -even polished- from 1"-6" in diameter). So far its only cost me 48$ for all the 2" bends and straight pipe I need to build my truck manifold turbo kit. I'm not sure if any one has had experience with using this food grade stainless steel but it seems to be very good quality, thick, but surprisingly not to heavy (Roughly 10 lbs total for everything).

I built my first merge pipe with 2 1/2" 16 gauge mild steel, but I feel that even with a nice brace, it will eventually crack on me therefore; I am going to be making a twin-scroll setup for my divided Garrett GT4202 1.28 A/R turbo on my LQ9. I went with 2" piping which will be divided all the way into my T4 flange.

They even sell v-band type clamps for the same 4$ a pound, which I could probaby get 5-10 two inch clamps with flanges for 4$!!! Compared to regular v-bands that are 50$ a pop. I am not positive that the band clamps will hold exhaust gasses, but for the price its worth a shot. (I'll get a picture of them next time I go)

This is my first merge pipe

This is the new 2" Sch 10 stainless steel ($48.00 total for all this) I had around $100.00 total in to my mild steel mandrel bends! ugh

It even has these nice edges to Tig weld into.

Let me know what you guys think, have I stumbled across a cheap way to have a heavy duty stainless steel hot side? Or am I missing something here. lol

Sorry guys I need to figure out why the photos are not embedding. FML

Thats pretty much industry standard stuff for quality turbo manifolds. You mig welding that?

jlee29

iTrader: (5)

Thats what i was thinking, Its extremly nice quality, especially for the price. I will be TIG welding this. I will post up pictures once I make some progress. I wanted to make sure it was safe to use before I went ahead and started building.

Not many guys on here use schedule 10 idk why. I used it because I wanted something durable and its the best quality you can get. So your going 2" ID and a gt4202 turbo? If you have access to all that stuff ill buy some from you.

If you haven't seen my kit here's the hotside
Twin scroll 2.5" ID

I've been building with sch 10 for about 10 years now. Works great. I tig everything. I've been building imports mostly.

I wouldn't use anything larger then a 1.5" sch 10 (1.6" ID & 1.9" OD) unless on a rotary, merge to a flange or crossover. I use 304 SS. you can get 316 but both are technically sub par for the environment of use. Don't even try sourcing 321, it's custom order and you could buy a new car for the price of the material.

check out this link, fourth post down. Manifolds are sch 10 (or 40)

some C6 TT manifolds I built last year.

I think quite a few actually do. For race cars people use tube, like .065 wall, much lighter and weight matters. Street cars the sch. 10 pipe is great because it hold up to the vibrations and road abuse, and much cheaper than tubing.

I haven't seen many on here man. Its not much heavier really. But it definitely is way more expensive than a lot of the stuff people use. Most the cars on here are street cars.

boostedsl2

It's way cheaper. Long radius 90 = $5, 1' straight = $7. Usually do a whole side for $100-150.

Cheaper if you're building something from scratch. Obviously it doesn't compare to $40 used truck manifolds.

this is the best pricing ive been able to find online, but I get it a bit cheaper locally.

Ace is a great place to buy. Only downfall is if you are on the east coast (like me).

www.rjsales.com

www.treadstoneperformance.com - short radius 90's come in sch 30 which is weird, but they are dirt cheap and they fit up ok to sch 10. They are ok on their regular long radius bends.

snapc3

Ive purchased 1.5" stainless 90s from www.rjsales.com. If you get a larger quantity they have very good prices. I got 25 pcs at 4.40 each, and quoted less for a larger order.

Great info guys, thanks! Yes I am using 2" for a twin scroll Gt4202 do you think that is too small? I was hoping it would help provide a quick spool time. I will be running a 3 1/2" dump out the fender. I don't think ill have issues with backpressure, but I could be wrong. We need to spread the word on here to save people some money and end up with a sturdy and good quality setup.

I think 2" will be great for it theres a lot of debate on here about it but all i know is what works for my set up 2.5" S480 spool time 3100.......But with the gt42 i think 2 is going to be awesome and should spool right up.
I agree with you about making a sturdy quality set up not sure why it isnt done more. The whole budget turbo build thing doesnt exist imo

boostedsl2

I'm assuming you're running a 2" pipe to each inlet on the flange (divided)?

I'm building a setup right now for my truck with a S480, 1.25 a/r divided housing. Doing the 2 2" sch 10 pipes, one to each port no the flange.

For reference - 2" Sch 10 - OD = 2.375", ID = 2.157"

Yes sir I will be running a 2" pipe for each bank, then into each inlet on the flange (Divided). Basically what I had before but just keeping bank 1 and bank 2 seperate all the way to the turbo.
Now the tricky part is going to be running a single wastegate and still keep it seperate. I am assuming i'll just run a pipe off of each bank (maybe 1-1 1/2" pipe) and make a merge into my wastegate? I am using a Precision 46mm. I plan to keep the boost between 10-16 psi.
boostedls2- Great minds think alike!
Camaro9969- I really like your merge!

boostedsl2

Yeah, that's what I would do if i only had a single. Might consider running two though. I'm running twin turbosmart 45mm. can't really have too much wastegate.

are you planning on recirculating into the downpipe?

boostedsl2

Do you have a build thread? Your welding fab/welding is awesome.

Camaro9969

Thank you.
The thread should be right in my signature

Camaro9969

iTrader: (12)

Thanks man!
Any reason why your doing one gate instead of two? If its price my two tial mvs gates were cheaper than one 60mm fwiw
