Any of you guys used this manifolds on a fc?

http://cgi.ebay.com/ebaymotors/ws/eB...981802280&rd=1

It seems much smaller than the other manifolds like the mk3 supra one...maybe this will give it a little more holding power? Seems pretty good for the money but I wonder if it makes a difference on disapating heat and improving flow.

I see no reson to use that manifold, for anything other than looks.

The mainfolds suck so do the elbows and so does most of the stuff from SSAC/SM and all it's many many itterations..

I've rebuild ~ 15 of those headers for peole who bought them , used them then watched them die, or plain old tried to nip it in the bud ahead of time.. mild steel flanges TOP WELDED ( as if ) to stainles steel tube.. the 'gussets' have no structural bearing at all, the insides are chewed up from what looks like 40 blind chineese kids with dull bits hacking away at the ports.. From TIG welding the crap I can say 100% that the stainless they use is FULL of impurities.. ( most of this structural info applies to thier exhausts and turbo elbows as well.. ). the fasterners they send with the parts are not even a 8.8 grade and most of the time have some form of crossed thread or out of spec nut issue.

but if you need to be cheap then it's the way to go.. that way when it does blow up you'll have learned an important lesson : you get what you pay for..

I don't know if any of you guys are from the NE section, but if anyone went to Voskos last Hooters meet. You guys should remember a red bubbleback w/ a red cf hood. Well the owner is a close friend of mines & he decided to buy the whole ss auto chrome turbo kit for $700. The kit didn't last for 2 months. He never really pushed the car or let it boost past 5psi. The first thing to go was the manifold. The manifold had too many welds & it cracked at one of the welds. He bought another manifold from ss autochrome & it had less welds & was better made, but then 3 weeks later the wastegate got stuck shut & the vtec was opening up before the turbo started even spoolin'. Then eventually the turbo stopped spoolin' up completely & we figured out that the turbo had seen its last days. Now the car just sits in a storage garage waiting for a new turbo & wastegate.

I also bought the fc ss autochrome manifold, with a REAL HKS wastegate & plan on using it on with a Big Kahuna turbo. Ill let you guys know how it works.

OK, i finally got a few pics up and here they are http://www.supermotors.org/vehicles/...=26333#content

My manifold looks nothing like any of the manifolds people posted on here. My manifold has really thick flanges and piping and the welds look very proffessional almost machine like really. Ill try and get more pics up as i get more time. As of now i am pulling a consistent 2psi daily and it runs perfect. My wastegate is opening a little early for the spring i have in it, so i need to get a manual boost controller to straighten things out.

2psi on a 60-1.. ? is that even possible. and with 2psi your already coming across issues ( where did you even find a 2 psi spring?.. )

bah, i've learned never to argue with ricers, they just ' don't get it' .. good luck dude.. kharma has a nasty backswing..

so, wait, just because i put a turbo on my car, that makes me a ricer? I dont have no 20" dubs or no big *** spoiler. So what makes me a ricer, explain it to me? I built my car to be a sleeper, and i think i def. accomplished that.

my definition of a ricer is; one that is given overwhelming evidence that contradicts everything they are saying/believing, yet continues to deny even the remote possiblity that what they bought , is NOT the 'schznit'.. given that almost every post has given you large negative feed back on the part and /or pointed to many many other threads in other groups that point to the same argument.. you still seem to be denying anything..

Dude. I can almost guarantee that you'll be making a post about how much your cheap turbo kit sucks donkey *****. I mean come on. You bought a brand new huge *** turbo for 250 bucks. How ******* good can it possibly be

I've actually held one in my hands and I laughed my head off. The nut holding the compressor blade on was even loose so there you have it quality is expensive. Crap is cheap.

And your blinky light autometer a/f gauge cant really tell you if your running LEAN or not. It reads a 0-1 volts signal. Get a 0-5 volt wideband and it'll tell you your running lean for sure

All the blinky gauge does is tells you if your in open/closed loop.

any full t04 turbo ebay or not will most likely smoke your motor because you still have stock ems. Stock ems and stock timing don't mix with full t04's

You're probably only boosting 2 psi because of the huge boost leak you have caused by those Home Depot couplers. I used those on my girl's boosted prelude and they leak and pop off like crazy.

This business of 2-3 psi make it a ricemobile with forced induction. Does this "sleeper" do anything beside idle and sleep; does it move forward?

whatever, i dont even know why i even posted on here. I kinda figured i would get flamed for running this ****. O well, i really dont care, my car runs, and it runs damn good. Pulls hard and doesnt smoke. If i blow my motor up im gonna buy a T2 anyhow, since you guys think they are god, i just figured id try to see what i could get out of this motor since alot of people on here never really tried.

good, bad, indifferent.....

Its a good thing that Albert Einstein wasn't a member of this forum, with all of you pseudo intelligent types on it he would have given up on physics becasue he would be considered a ricer for trying something you guys claimed was impossible.

To Flatlandin_man23, keep trying, it might work, it might not the only thing that matters is that you are happy with it.

the problem you are having, is you are trying to satisfy somebody else, DON'T, the jokers here never have anything positive to say unless its to one of there narrow minded friends.

good luck, and for the rest of the peanut gallery, don't bother i don't answer childish emails or PM's

how much hp would 2psi add? you could have spent the money on one of those scam electric turbos for $50 and addmore power then 2psi on that thing.

turn it up to 10psi and see what happends. there are people with turbo n/a 7s on here.. you can make it work right, there is a local guy making 220rw with a stock tii turbo on a gxl motor. he used a tii UIM and TB tho. still runs the stock ecu... i would do it the right way but it can be done the wrong way. but please do something..

2psi? bahh all that money for 2psi... i fart more than 2psi.

I knew this would happen as soon as I typed it..

From my point what I said was not in reference to something that had not been tried .. experimentation on something totally new does not have pages and pages of results to the contrairy, such as this.. so your comparison is moot and very forced...

Pulls hard and doesnt smoke.
on 2 psi? how does one have a hard pulling car on 2 psi ? unless the car says Yokomo or Tamiya on it 2psi on a 60-1 is not going to ammount to.... in fact 2psi is not even measureable from the compressor chart, your below min flow specs by quite a bit. this whole 2 psi thing is goofy.. where do you get an actuator or WG spring to open at 2psi ??

I wouldn't consider one of their turbo's..


but i'm seriously considering one of the T4 manifolds for my FC

just take it to a welding shop, and have it Re-inforced before starting to use it...

no big deal..

Otherwise does anyone know where to get a REASONABLY priced FC T4 Tubular manifold?

**** the bull ****...modifing cars is fun. He's turbo'd an N/A motor in a car from the 80's...and it runs. Not everyone has $$$$ to throw at these fawking rotary engines, some wouldn't spend the money to change the oil in a car from the 80's.

props to you man.

and if he blows it up...big deal, who hasn't blown up a rotary enigne?

It ran better before installation of teh monsta' turbo that makes krazy 2 psi boost. We haven't seen proof that this thing moves forward being that it's a sleeper and such.

Yeah, not everyone has the $$$ to do it right, but they always have the $$$ to do it twice.

problem with the header on the most basic level is that they use mild steel flanges ( painted with some metallic spray afterwelding to make it look like stainless in pics.. ) then SURFACE weld stainless tube to it.. absolutely the BEST way to get expansion stress on each weld.
Also SSAC seems to have the customer service of a projects crack addict after 12hrs dry..

If that's the case just get the cheap manifold ceramic coated to help deal with the differant ways the differant metals will expand and hopefully cut down on stress cracking.

thats what I was thinking about doing with mine. I saw in one magazine where they were talking about covering the manifolds in sterling to lower down the temps & reinforce them. Supposedly the company that does this job does it for cheap too. The ad I think was in this months SuperStreet.

exactly, thanks for some positive responses guys....the only reason i didnt turn it up yet is because i dont have a fuel pump or injectors in yet, as soon as i get them its gettin bumped up to 5 psi to see how it runs there. 2psi is insanely noticeable on a n/a engine, if you have never tried it, dont say it wont do ****, because it is def. noticable compared to driving it n/a, hell of a lot more power up top then what there used to be. Anywayz, for the people that do care, i will keep posting results everynow and then when i start upping the boost.
