FC gt35r build advice
 

Wassup guys, in the future I want to put together a whole setup for a gt3582r 1.06 v band divided t4. What exactly would this require? I have a frontmount, a power FC, 1000cc inj, and a walbro 255. I'd imagine I'd need a new manifold(do people usually pay like 900 for one of these? That's the price for some of the better looking ones I've seen). Also, do people generally opt for the double ewg setup? And if so, why?
Is there a benefit to routing the manifold higher up into the engine bay like most do? Accessibility? Are there any differences between rhd and lhd? What would be a reasonable amount to spend on building a setup based around this turbo? I'd be open to buying a whole kit(any recommendations that aren't discontinued?), but I'd like to learn, so I kinda wanted to source all my parts n design my own setup.

Any advice welcome,
Carrington

Also, my goals are about 400hp. Will be mostly used on street, occasional road courses.

Borg warner efr8374 should be a consideration - will make your 400hp more easily than the gt35 and the peddle response is unparalleled. Nothing wrong with the gt35 if you already have it though.
They also come in an internal wastegate format which has many advantages, but boost control can be marginal in some cases.

The twin wastegate thing is to capitalise on any benefits of the split-pulse turbine housing. Once you put a single wastegate on you have created a "bridge" between the runners that negates the twin scroll/split-pulse idea. The theory is it will give you more response and quicker spooling down low, but the effects are small.

The high-mount might be good for keeping radiant heat of your intake runners, but often at the expense of air filter size or air intake routing. I'm a fan of low mount and lots of heat shield but that's just me. Also a short runner manifold will theoretically transfer energy to the turbine more efficiently, but the difference is probably a fart in a high wind.

as to the price of the manifolds, a lot of work goes in to doing it properly so thats the price of quality I'm afraid.

Punch any of your queries into the search engine on here (or google which will bring you back here more often than not) as its all been covered pretty extensively.

If you go to TurboSource's site, Eliott answers nearly every one of your questions rapid fire in his manifold/kit descriptions. He also copies the same post onto this site in his classified.

Hey, shoot any questions you have to john@gleasemanufacturing.com, happy to help you out.

For an FC3S chassis on a medium frame turbo its best to use this manifold design of ours;

FC3S Rx7 Short Twinscroll Turbo Manifold

Generally people use vband turbine housings because they are tired of gasket/stud/nut failures. Only full blown race cars truly benefit from the easy of installation/removal. We have optional inconel studs, nuts, and gaskets that do not fail.

You injector and pump combo is too small for even a Gt35R at moderate boost pressures. It would be wise to choose a different turbo. If you are on a budget you cannot beat our TDX line of turbochargers;

Turblown TDX Series Turbochargers

These are all hand assembled in the USA, and I have never had a unit bad out of the box, ever. Never seen one fail from a manufacturer defect either. They actually make slightly more power at high boost vs an EFR, but they are roughly 600rpms slower.


Boost control becomes an issue with smaller single wastegate manifolds, and one gets better boost response with a fully divided( twin scroll) turbo system. The pulses keep separated with maximum velocity.

The above manifold is in stock too and ready to ship.

appreciate all the input guys. those efr turbos sound pretty nice. hella pricey, but im not in a rush on my build, i could stand to save up.
as far as the tdx, i couldnt find too much feedback on em. they sound good though. but since itd be about 1500 w/ the ball bearing option anyway, would it be best to opt for maybe a efg 7670 or would a tdx57r be better? would my current fuel setup support either?

this is also something im thinking about. waiting on my buddy to hear a lil more on the specs, but does it look reasonable? whats the most some of you would pay for this?

Most people purchase the TDX turbos in journal bearing form. Not a huge difference between the two in performance really. So starting at $1000 the TDX is a very good bang for the buck.

You're current fuel system will support roughly 12 psi on either the TDX57 or EFR 7670.

That cast TO4E kit you have pictured will work fine too if on a budget. That kit used is probably worth $1500 ish.

BorgWarner S200SX-E

how do you feel this turbo stacks up vs the TDX 57..?

The TDX57 is a better turbo for a 2 rotor engine compared to the s200sxe. The bigger turbine wheel better suites the higher rpms, especially for a sustained duration like roadcourse racing.

On a proper turbo system it will see 15 psi by 3k rpms and make 400rwhp at 15 to 16 psi.

the TDX57 is the smallest you produce? i'm looking for sooner spool.. if need more room for exhaust then i'll just run two of them. sequentially.

i was thinking of trying out the 200sxe to see if it would spool 20psi by 2.5k rpm. im looking for something small as the 7064 efr. which i think that is the compressor for the 200sxe.. and as is the 7670 also a 200sxe version.
spool 10psi by 2.5k rpm. ona 2 rotor.. then put two of them seq on a 20b.
2k rpm spool. 800-900hp.

sorry if i have derailed this thread with a hint of my future build.
just seems like a good place to talk about the spooling of NEW turbos, the TDX have been around for some time, im all latest and greatest :)
not knocking them or anything..

20 psi by 2.5k RPMS will require an EFR, no doubt about it..

I'm lucky to have just taken a job that has two mustang dynos... and does lots of performance tuning stuff, just nothing rotary.. yet.... we shall see what the s200 CAN do.. it's stupid cheap $850?
the manifold and lines will be fun practice... and a chance to show my new boss what i can do on my own budget.

is my setup alright for a 8374? by reading some past posts, itd seem that the boost response is already so good in an 8374 that i might as well go with that over a 7670.

how can i use turbo size and psi to decide whether ill have enough fuel or not for certain setups?

FYI we can do smaller, it just does not make a lot of sense on a rotary. Anything smaller than a 7670, s200SXE or TDX57 will run out of steam by 5.5k...

Also I would not use a P trim size turbine wheel with anything smaller, maybe a stageV turbine wheel...

The 8374 does have great response, and can be close to the 7670 if you have the right variables( 3.5" exhaust, short interccooler plumbing, 4" intake, etc etc ). d


If you are looking to purchase the EFR, etc from us I will tell you the rest of your questions via email.

Get something new and nice looking :D don't strap a poo to the side of your engine. lol =D
EFR EFR!

Be a man and buy it!

Haha eventually.. I don't got enough money for everything rn..

I run a 3582r 1.06 t4 setup on my FD and am very happy with it. I run it at 17psi and see 10psi by 2800rpm and full boost by 3500, so the efr's seem to have a big advantage here. My fueling setup is 725/1600 with a denso supra pump and water injection. Using an HKS tubular manifold with single Tial V44 wastegate and 3" exhaust.

That kit might be good if it is what he says it is and it isnt flogged out. If thats a 3582r with a 1.06 it will be pretty awesome circuit/street setup on that manifold. Get it checked out and see if you can work out a good price. It looks ratty which might work in your favour price wise. can polish the compressor housing if you are worried about looks.

Sorry, just saw that its a t04e, derp. Can still make good power and excellent response. Would be worth looking into if it all checks out and you can get it cheap enough.
I was getting 330rwhp and zero lag with a s4 hybrid turbo (57mm compressor) and a cast log manifold that looked a lot like the one in your ad on an extend port built from 2nd rate parts.

well that guy never got back to me anyway.. i can probably find something pretty cheap when i get back to japan though, we'll see.

I was talking to my buddy about the awesome results rotary guys are getting from these efr turbos. He worked for a shop that has a quiet well known time attack evo. For them, they have had nothing but problems with their efr turbos. they blew one turbo on the first session. Got another new one and blew it again. I'm not sure if it was because the efr turbos were still in their early stages of testing, or if these turbos aren't well suited for very high boost levels during these 15 to 20 minutes. I also heard of another team having issues with theirs also.

Garrett makes good turbos too, but I would still get an efr turbo for my rotary just because those response numbers are soo awesome! I like the idea of just having an internally wastegated turbo. Figure one wastegate, maybe 2, and the flanges and fabrication for the dump tubes, or even more fabrication to have it rerouted to the main exhaust

S4 GTX3582r with Tial V-band SST 1.03AR housing. Dual Tial MV-44 WGs. 3.5" down pipe into 3" collector into Borla cat back.

I had to rebuild original manifold due to poor single wastegate location and boost creep. 372HP@5800/17psi.

"Remora" WGs routed back into downpipe. Curved WG pipes at transition fixed creep.

I haven't dynoed the car with new waste gates but expect 400HP is doable around 15psi.
