Yeah, that might get a touch expensive. How's the "vacation" going? We got the Mickey T's in, and they don't fit with out raising the car WAY up. Going to get adam to do an alignment here in a hour.

I don't know when I will be able to get pics of the fit in a S chassis. I'm depending on somebody else's car for that, so I'm at their mercy.

If and when I get them, I will post them. If you need some faster, I'd suggest buying one and fitting it on a 240. Mine was bought to put in my rb26 powered Z car, so I will try and do my best to try it in a S chassis, but I can't make my friend do it, I have to wait till its ready...

The manifold came just as you see in the pics. There is nothing that will come off into the turbo. As far as corroding? I think a mild steel would be the first to do that. If I had a sand blaster, I'd blast the inside of the collector as the 6boost was.

If I get pics, I will post them. Until then... see ya.

[QUOTE=Darius]call me a b**** but I would still rather have my 6boost. Soon to be running btw. Shouldnt be much past May 1!

EDIT: Not to be a wet blanket on a fire, but the collector on that manifold looks like d!ck. I'd be worried about some of that choppy weld material eventually corroding, breaking loose, and running through the turbo. You get what you pay for I suppose.

Did it come like that or did you have to port it out to clean it up?

EDIT 2: Here's what it should look like.



Absolutely beautiful collector!!

that 19cm housing fits in there nicely. i thought my hx52 w/ the 16cm is already big. from the look of it the hood shouldhttp://img181.imageshack.us/my.php?image=dcp0824be4.jpg have any issue closing.

that picture freaks me out, seems like metal-termintes had a hold on it. i can imagine how bad it looks before imperfections are filed down. all that filing down, i'm not sure about the integrity of the weld, as the beads are to be the strenght of the joint, fillling it flat down is questionable for longevity. btw! are those rusts? stainless shouldn't be rusted, if it is.

wayyyy under par comparing to the 6boost collector.

here's my old ebay manifold setup during mocking up phases. gives you an idea of what happens when it goes into LHD. you need to drastically shorten the wastegate tubes (like mine), or lengthen them. helps that the tial44mm is small compared to greddy/hks. fitment of fearsome_tea's manifold is most likely similar. my old setup is for sale if anyone is interested.

That is a nice collector, I do not use sheets in my manifolds at all, it is all pipe, same material. I have found pipe to be much stronger than a sheet of sus. It will handle more heat, and last much longer. I have never had one of my 321 manifolds crack, and i doubt I ever will. If you like that manifold, I am happy for you then go with it. Is my manifold ground out? why yes it is it is 2.8mm pipe, not a bunch of sheets cut out to make piping fit right. Do I use really cool machines called pulse tigs to make a perfect looking weld even if it is accually mig welded? no I dont as it causes massive amounts of contamination. Can people take 1500$ and make a really nice manifold? yes they can, that is not what i am offering. I am offering by far the highest quality piece that most people can afford, something strong enough you dont have to worry about it breaking, cracking or failing, in a design that I know works well. that is the buisness I am in, not making stuff that is appealing to the eye so you can bolt it on a car show that can never run. If you want to build a $100k drag car, then look someplace else.

hey how much do you want for your manifold with wastegate? what mounts do you have and about how much cleareance from the steering shaft and wastegate did you have? let me know cause i might take you up on that offer.

I'm crossing my fingers to see if this will work in an S-chassis.

I dunno about the S chassis fitment, but just FYI on mine (in a Skyline), I've had this thing glowing bright enough to read a book with at night several times playing around in the twisties, and still no cracking.

Sorry, the manifold is still in the box it came in, sitting on a shelf in my shop. The chassis I had lined up to try the fit on fell thru for me....

I bought a LoveFab manifold from a board member, and I will be fitting it shortly, so I prolly will never need this one if anyone wants to pick up where I left off with it.$400 + shipping.

Well, if you have the cash to pay for a 6boost or full race, by all means, go for it. They are nice pieces with real pretty collectors. I'm concerned with my manifold not ever cracking and I'm not afraid to attack things with a die grinder, so I'll stick with my Stec mani.

My cousin in gushikawa oki is running a s-tec on his r33 gtr, he beats the piss out of the car (nago) and never had any issues with the manifold, I will be ordering a s-tec here after my car goes back together.

I read about this manifold in another thread but had no idea what it was, It's nice to see this thread, aside from having a perfect looking collector, it seems like a well built piece.

I like this mani. Its maker is on the forums and that deserve big kudos.

I will hopefully have the money after christmas.

And i will take pictures for whoever wants them.

How much is shipping for this piece?

And fyi i will be fitting it with a stock t28 or a to4e so nothing insane but will still measure out the clearences for everyone.

What would be the point in going top mount with a T28? You may want to check out some of the top vs bottom mount threads so you can get a good understanding of the purpose of top mount.

I understand your concern but i am buying it INCASE i go for something bigger... my plan changes daily and if i was able to get a bigger turbo for a good price i would do it.

Going bigger would require an upgraded fuel system as well, AND a tune so you'll need more than this manifold when you go bigger. Buying this manifold and bolting it to your motor with your T28 would still be pointless. NOW, if you would want this manifold to put up until you get your bigger turbo, THAT would make sense. Besides, your T28 is a T2... This manifold is for T3s..

Stock turbo is T3, the Stec top mount is T4. The sidemount is T3 though. Either way, you can't bolt a stock turbo up to the top mount, and even if you could, you'd need to have custom intake piping, a down pipe, block off the wastegate runner, etc. made. Don't bother with one of these if you plan to try and put a stock turbo on it.

ugh.... I try to state my point but that doesnt happen...

So anyways I have a built bottom end im not sure what im going with for a setup but it will be nistune plus 550cc+ injectors. Im not going to use a T28 turbo on the mani i was going to put it on and measure it for people so they would know if it would fit LHD. I understand everything you guys just said but hear me out. I dont intend to use a t2 turbo on a t4 top mount. Especially when my t28 is 100% blown.

The incase i go bigger was to say incase i go to a bigger turbo along with my setup. I dont want to go from stock then 400+hp. I honestly couldnt handle a car like that right now. The most hp car i have driven is my stock RB and i think that if i just doubled the output it would only end with me in a bag.

Just calm down a little bit

So whats up with these mani'si think i want one, no i know i want onebut i have questions1. Can you (s-tec) make mine with dual 38mm wastegate flanges already installed so it will be true twinscroll?2. Will it cost significantly more to do so?3. Does anyone have a 19cm non wastegated housing for an hx40 laying around that i can purchase?thanks
