So I'm trying to figure out which manifold would work best to single my sc300. I'm very hesitant to go the ebay/ xs power manifold route due to fitment issues on the distributor and how close it comes to the throttle body above the turbine housing. However the pricing of the ebay manifold wins, and I could always delete the distributor and go FFIM :D.

Treadstone has pictures of it mounted to an is300, but not the sc300 or supra. From the other thread:

But does it fit in the sc300 / supra engine bay with a Billet 6765 / 6265 on it?

Almost looks like it would be more distributor friendly as well.

So what do you guys think? 400 bucks for a brand new cast manifold that won't break. The fitment looks like it mounts the turbo lower than the distributor so no more fitment issues there as well as the manifold sits the turbine housing underneath it so the throttle body clearance is no longer an issue. This makes me wonder why no one uses it more or at all for that matter? I'd probably use their wastegate adapter from 38-44 vband and port the wastegate hole as much as possible to prevent creep.

It doesn't look like it makes the overall height of the wastegate much taller either which is good.

Also, IF fitment near the frame is good, a quick spool valve can be used because the manifold is undivided :D.

I've been waiting for another Boostlogic GE manifold to pop up on the supra forums for sale used but no luck. At least I know those for sure clear the distributor well. I contacted boostlogic to purchase just them manifold from the and they quoted me $1500 just for the manifold :eek2:. Just trying to find some other good options. Anyone have any feedback on this manifold?

From the look of it, it seems like the distributer would be in the way on a supra or sc.

I think you're thinking about it too much, if you're planning on going with a smaller turbo you will be fine with anything with a 3" inlet.

Just go with a TT ECU and delete the distributor and the MAF, then go with a FFIM and you will then be able to run any size turbo with no issues

I'd like to do at least a precision 6265, which has the 4" inlet. 2.5" outlet compressor housing, and a open .81 v-band t4 exhaust housing.

I'll probably use aem ems, delete the maf, and go with is300 coil packs, and possibly switch the 7mgte cps if needed.

What manifold do you recommend?

I'm running an xspower manifold and I'm more than happy with it, I just sold a drewgo manifold earlier this week, look on the classifieds, there's always someone selling some kind of na-t manifold, if you're planning on deleting the dizzy and going with a 7M CPS then you really don't have any fitment issues to worry about

that manifold will clear the distributor just by looking at the position of the turbo. it sits very low so i don't see any fitment issues there. even if it didn't somehow, you could just use an angled coupler to get the pipe to fit. that is what i've done with my manifold. i'm installing the 7M CPS soon with coilpacks so it won't be an issue. it's not now anyways.

if you're worried just get the xspower manifold, clean it up and brace it. problem solved.

I'm bumping this up.... To see if anyone actually confirmed whether or not there are distrbutor clearance issues. I have a 6266 and want to know. Thanks
 
#12 ·
Yeah that's what I went with just ordered some coils and an igniter the pro efi 128 shouldn't have a problem with that ;) just more damn wiring I gotta do now

Here's a quote from Clublexus. I'm running a 61mm turbo with a .68 exhaust housing.
here you go guys

Sorry I never posted up. I was trying to get ready for a road-race session on Thursday, which didn't happen. I got everything installed but ran into complications. I had massive boost leaks, and still can't build any boost. My BOV was leaking from the vacuum port and would stick open under any pressure. After pressure testing I was also leaking from the intake manifold/ lower runners, even with a fresh gasket, also the IACV port and a coupler or two. I don't know if FIPG gasket is a good idea for the intake manifold, seeing how the stock gasket is not working.

Also my wastegate seemed to be letting exhaust out at idle. I haven't diagnosed the wastegate yet. The wastegate mounting is kind of weird IMO, I had to buy a 1.5" flex line to run down under the car. The exhaust housing has an opening in between the turbine housing, but I'm unable to tell if it's leaking with the fan blowing. I had to cut most of the studs to fit the manifold, although I've done this with every 2JZ exhaust manifold. The generic 3" ebay downpipe works better with this lowered manifold. The 4" intake pipe fits fine and clears the distributor easily. Compressor clearence isn't an issue, but Turbine housing will be with larger turbos hitting the shock tower.

I'll update when I get this POS working correctly.

Anyways here are some pics.

port the wastegate hold sor a tial mvr 44 with the adapter they sell and you'll have no issues at all.... sound performance is even using this manifold in their "tourque monster kit".

i am running the treadstone manifold on my 2jzgte sc300 an i love it.significant difference from my tubular manifold spool time wise. And am running a 6765 with BL trans and 3800 stall. pending dyno results. But mine is extremely ported.
 
#19 ·
Yes im thinking of one of thses myself, anyone know of any rhd clearence issues? And it would fit a prescision 6266 on it?
 
#20 ·
This is the route im planning on going, what turbos seem to go good with this manifold ? Im planning on running precision turbo of some sort how ever im on a bit of a budget so im piecing my kit together... Im thinking about something small, i dont want more than mid 300 HP and i like response.

I think the placement is where it is for the cross over intake.. it looks to be just behind the TB, if it were like the GTE it wouldnt have enough room for the piping. you would have to literally have some sort of pipe that relocates the WG back towards the firewall.

Ultimately as long as the pressure is being relieved im sure it works perfectly.. i plan on getting this exact manifold this year along with precision 5858... im excited
 
#23 ·
Well I think it should be pretty standard to go front facing intake manifold if your going to turbo this manifold... And if tread stone made a 2jzgte manifold with a GE flange it would completely outsell their current product. I would buy one if it had correct placement.
 
#24 ·
the bolt pattern is different between the GTE's and the GE's as well. they can't design an NA-T manifold based off of the fact that people for certain will be getting the FFIM on their cars.
 
#25 ·
well usually you only really need FFIM if your going with an upright turbo where the hotside is literally just inches from the TB.

With tread stone the turbo is clear from the intake so theres no where near the same amount of heat on the intake... Thats the good think about this mani is the fact that it makes it possible to have boost with out having too much heat soak... The fact that the turbo is literally as low as it is, the heat will simply just immediately flow out the bottom of the bay.

In my opinion this is the ultimate manifold for an na-t enthusiast. Temps remain generally lower than that of an upright, wont risk melting countless couplings on the TB, and low profile is always nice to have.

I soon hope to be able to afford this manifold !

I know this is the NA-T section but I wanted to just leave some feedback about this manifold on the GTE. Bought the manifold through SP who did the porting and did the heat coating plus I had the 46mm wastegate adapter installed as well....the mani looks great and it should flow very nicely with the porting done. I will try to get some pictures as soon as I get some free time so you can see the quality of the mani and the additional work done by SP.

the 2jzgte manifold by them is a different design, with the wastegate in a much better location. Of course SP has had good luck with this manifold because they can further port the wastegate entry to alleviate some boost creep, and because the way it faces the turbo slightly "upward" and not downward and to the side like the NA version of the manifold they can install their quick spool valve..

It think having a badly designed manifold JUST to clear some excessive intake tubing is pointless.. but thats why xs power makes another budget manifold that actually might work if reinforced along with more expensive tubular options... and if you're still too cheap to reroute your intercooler piping just live with the heat soak of a bad combination of parts.
