4G64 T3 Manifold

[PharmEcis]

Here is a sneak peak of something that will be an option soon. Need to make a couple of changes but this manifold clears the starter, clutch slave cylinder (if 5spd swapped), A/C and lines, stock fans, etc.

The wastegate can either dump to atmosphere or it could be recirculated back into the downpipe. I think I actually might be able to fit a full 3" downpipe with this setup but don't quote me on that yet until I have a chance to fully test fit this puppy. I'm really happy with where the turbo sits in this setup because it really has awesome clearances all around and doesn't require the removal / relocation of anything up front. More pics to come as I proceed in the build.

Once I come up with something I'm 100% happy with, I'll begin making full kits. :D

Heyy man nice engine, is that an Evo manifold?

[PharmEcis]

This manifold is designed for the 4G64 found in the Galant, 3G Eclipse, 2G Stratus, etc. It will work on both SOHC and DOHC head configurations in those platforms.

[Gtorque]

nice job man..looks great

[Shadow19]

Man that is sexy! What is the price range on the manifold alone?

[PharmEcis]

Manifold is built out of stainless 304 schedule 10. Material isn't cheap and this manifold is quite labor intensive. A ballpark range would be $800 to $1,000 on the manifold alone flanged for whatever turbo / wastegate you want.

I will probably come up with a much simpler design that is easier to build which can be considered a "budget" or "street" manifold as I should be able to price it fairly lower than the manifold above. You could call the manifold above a "pro" or "race" manifold.

thats an interesting option. Im using a dsm t3 manifold that puts the WG on the driver side. this would definately give people more clearance for avoiding the A/C and more room for a larger downpipe

[PharmEcis]

I'll post some pics of the kind of clearances this has once I put it on the car. ;)

QNZ you know you can have that wastegate elbow cut and flipped 180* so the wastegate flange sites on the passenger side


PharmEcis that looks like a great design im interested to see the fitment when you get done, can you put the stock evo8 flange on one? i know its divided but just and idea.

[qnz]

underrated, not sure what you mean by cutting the WG elbow? I dont think my manifold design allows for it. also DSM manifolds place the turbo about 2"-3" closer to the passenger side. if the WG is moved to the passenger side, the dumptube might be tight to fit around the AC or power steering.

heres an old pic of my engine bay

notice my downpipe wrapped 180* around and back behind the turbo.

[underated]

you see how the wastegate flange is on the driver side, you can have it cut off then rewelded onto the passenger side... its not necessary but just and option you have a very clean setup as it sits right now

[02galant]

That manifold is bad ass Pharm. Keep us posted.

[xd_01]

thats a nice manifold im guessing its clears the starter since you designed fit or the 3g/8g platform, and are you adding any kind of brace to help support the turbo?

Got clearance? I do! I'm pretty happy with how that turned out but the next one I build will definitely have some refinements / improvements.

Full kit details coming soon! :)

The downpipe in the pic looks like its 2.5", any ideas on trying to get a 3" downpipe to fit? Also, is that an E or S cover on the turbo? If its an E, try an S, because it might hit the starter and you may want to move turbo placement a few mm's further out to clear this. At the same time, the most comonly used S cover turbo's run ball bearing CHRA's which tend to "scroll" outwards more than the non-bb turbo's, so that might not even be an isssue.

The downpipe is 2.5" for less than 9" before it moves to 3". Yes I could fit a full 3" downpipe, I just didn't have the materials nor did I feel like screwing with it. The 2.5 was easy and honestly the performance difference will be negligible.

This turbo is ball bearing and this manifold will fit up to a full 35r with out hitting anything.

Yeah I know the performance end of it is negligible, I also run the same thing I have about 10 inches of 2.5 then it opens to 3". My concern wasnt for that factor, but more so if you run a true 35R with either the 4 bolt GT housing (not the T31) or a Vband housing, the outlet is 3", so it would be counter productive to have a bottle neck after the turbo. This of course wouldnt be an issue using the T31 or 5 bolt housing because those are both 2.5" outlets.

Nice

Is there a reason you didnt make it equal length? or close to it?

Also, im not sure if you've seen it yet, but AMS is selling a cast SS 4g63 bolt pattern exhaust manifold flange. Its a nice piece because it has the runner transition built in, so you can start your runners with schedule 10 without having to worry about welding them into the ports and re-shaping them to fit the oval ports.

[PharmEcis]

I didn't make it equal length because the benefits from doing so are marginal at best.

All my flanges for the 4G63 are machined from oval to circular for the s10. It doesn't have to be a cast piece.

[PharmEcis]

I finished up Wes' manifold. This will be the production version of the pro manifold. I found 180 degree schedule 10 cast pieces along with a different collector design which made fabrication much simpler at slightly less cost than the first manifold.

My flanges come CNC cut with the transition already built into the flange from the oval exhaust port to the round schedule 10.

Custom flanges built just for me! :)

This manifold can be configured for internal or external wastegate setups. What is pictured is for an internal. You have your choice of wastegate flange to match your setup.

[Stewi]

From that design I guess your running 5 bolt turbine housing with a wastegate port and running the wastegate off the o2 housing?

[seth98esT]

Nice manifold. You should throw the battery in the trunk or get a smaller Evo battery.

The manifold pictured will be externally gated. I just don't have the wastegate for it yet so that means I also don't have the flange. Probably going to put a 44 on it as I like the vband.

You mean a mini battery? They aren't EVO specific.

ok i gotta question about manifolds. so by reading this i understand that the more expensive the better, but whats the difference between this mani and the $200 ones on ebay? is it just the material or the way there built? im actually just wondering about this. i understand that this is probly a dumb question, but i honestly dont kno

you answered your own question. Better quality materials, better quality welds, more first hand experience on the part of the fabricator and design/R&D. Alot of these ebay manifolds are just copies of a manifold that someone spent alot of time on to do R&D work and then some tiawanese aftermarket company bought one, copied it, uses shit quality materials and sells it for a third of the price. Alot of these manifolds you see from the big names like Peakboost, ShearerFabrications and Full-Race all have a lifetime warranty against cracking and defects. The reason they can offer you such a great warranty is they are VERY VERY confident that the damn thing will never break, this is due to the R&D, superior workmanship and materials.

[PharmEcis]

Not to mention that there isn't a single manifold that was actually designed for these cars. All the manifolds you buy were designed for a different platform that just happen to fit this platform, but with fitment issues requiring spacers, ditching A/C etc.
