Modified Stock Manifoild For External Wastegate

Tired of boost creep issues? Frustrated with your internal gate not providing the response or spool you were looking for? Giving up on lack of true boost control? Well look no further than this modification!

Having tried all of the major internal gate upgrades on my personal car, as well as others, it gets to a point where you simply can not reasonably control bigger boost with the larger GT28+ internally gated turbos. While initially such products work, they eventually fail putting you right back to square one, however with the frustration that you spent your good money and it didn’t work.

A few years back I had my personal manifold modified to accept the traditional Tial 38mm wastegate to fend off these issues, and I’ve yet to look back since. Running a proper external wastegate allows for true control of your turbocharger, while also offering better spool up (as the little internal gate isn’t pushing open) as well as rock solid boost control when you’re wide open throttle.

This modification utilizes the stock manifold (proven time and time again to be the best option for bottom mounted turbos) and can be modified to accept any wastegate flange of your choice. The best option for final fitment IMO is the Tial 38mm MVS gate (v band) however all options will work 100% fine.

Pricing and Information:
The modification to the manifold is 100 dollars. You will need to provide your manifold, and your flange of choice. After the welding is complete we can either ship it back to you, or we can ship it anywhere else you choose (the popular option is Extrude Hone, or to a High Temp coating place such as Swain Tech).

Cody, been meaning to ask you, can you provide some pictures of it installed on your car? Curious to see how far up it sits in the engine bay.

Much appreciated.

Now the MVS are obviously shorter. It does clear all strut bars with ease.

anybody measured the weight difference between one of these and a Tomei or Doc Race tubular manifold? Just curious.

I don't have a stock manifold to modify, but if there was an option that included one and the weight difference isn't material I might be convinced to try it.

I do not have any specific data about the actual weight differences, but with that said I can assure you that with the actual weight difference to me (maybe less then 5 pounds total difference between them) is not a selling point, as it's been proven time and time again that the stock manifold promotes the fastest spooling turbo through heat retention, and is about as failproof as they come. Tubular manifolds are noted for less response, and there are countless examples of them cracking (to include Tomei and other name brands)

In the end, I wanted OEM reliability, but with reliable/failsafe boost control, and this was the way to go to achieve that.

I was going to buy a Doc Race tubular manifold with the T25-EWG-44 but will think about this as an alternative for my GT2871R. I will just have to find a stock manifold, which I can guess shouldn't be too hard.

oh ok.

was just wondering if you had had a screamer pipe configuration and how it was routed that was all.


This is never done in the UK.. everyone just switches to a copy of the tomei supreme manifold, internal wastegate and a gt2871r 0.64 running 1.5bar...

or to run less, just ported out the internal wastegate to 30mm... to prevent boost creap, which aint so much of an issue when opting for the 0.86 ex

But then we have ron 99 fuel fairly available... but dame its expensive!

On my personal car I welded the re route toegether for it. It uses flex pipe and the sort. Sure isn't pretty but it works. Routes right along the steering shaft and has no worries.

You will need to either weld your flapper shut, or to hold it shut (with wire, or with a piece of metal cut out to hold it. I don't have any pics off hand though :(

I'm sure Jay could weld it for you, but with that said, I do not have KA head around to test fit on for you. It's a circumstance of 'yes he can do that' but without the right tools/testing it's not fair to say yes.

Excellent upgrade and service from Cody. I am in Japan (military) and he went out of his way to send my manifold off to get the external gate flange welded on, and then sent it off to get honed, and then even sent it back to me...Might I add was also updating me very often with status updates.

Unfortunately My setup is currently apart so I dont have any pics.

However, I made a little bracket that connects to one of the 5 turbo to elbow bolts and then the other part attaches to the wastegate flapper. NEVER had any issues.

i had one of these put on last summer and it holds boost perfectly with the v band wastegate. i had the dump near the break lines like in the pic and had to move it since i would get massive break fade from doing a few hard runs in 4th or 5th gear, as in i would be going 100+ mph and step on the breaks and have to pump them to get them to stop. i quickly moved the dump so it dumps between the tranny and downpipe. be careful where you put the dump i had a friends engine bay catch fire from an improperly placed dump.

Hehe right up through the roof with a big rig flapper ontop :D


There is no doubt if running tit near the brake lines that you will need to run a better fluid and or wrap the lines (and wrap/coat the dump)...I personally have never had any fade issues on track days, but then again I do have it all at least BBQ painted and gold foil wrapped.

The V Band setup IMO is much nicer as it enables an infinite amount of variables in regard to dump placement.

Do you weld these yourself? Welding cast iron is not easy. I'm pretty sure it needs to be preheated pretty hot and special filler wire used. I'm guessing that you have done your research on this and weld it properly, right? Only asking because I'm interested in getting it done by you but was turned away by several shops when I wanted this done a couple years ago.

Cast iron is easy to weld...this isn't a structural piece, no preheating needed, no special wire needed. I've welded multiple GM cast iron manifolds into Turbo manifolds.

Dude, I've talked to several seasoned, professional welders, and none of them would go near cast iron, it has a different chemical composition than steel.

Also, It doesn't matter if it's structural or not, if the weld cracks you're leaking exhaust all over the place.

I was just trying to find out what process is being used for this so that I can decide whether or not to give it a try.

It's a matter of relevance to a degree. Is it a massive amount of change? Well, not really...it's sort of a nice finishing touch (we'll say like the cherry ontop) to a nice setup. It's going to help spool up without a doubt (smooth runners, no restriction), but it's not going to be a huge difference (100-200 rpm maybe)...it's also going to maybe be responsible for a few ponies, and better off boost response.

Is Extrude reaaaaally needed? Probably not. However (IMO only) if you're going to go that far with a setup, it's worth doing it right (especialyl if you're really going to drive the car...if it's just a daily driver then I'd probably opt out). I guess that though process could be applied to a most mods, but I'm just trying to be as truthful as possible :D

As far as a reduction in power, that's hard to say beyond educated guessing based upon results and dyno graphs. YOu'll gain faster spool up and torque with the stock manifold, but may loose out a smidge on the top end, which is where the tubular manifold does work best...however it's not a huge amount)

No my friend Jay welds these JPC Fabrication. I've sold about 15 of these so far with no issue, and Jay has welded countless other cast iron items at his shop. If it does break, you can ship it back, repaired and shipping will be covered on our end.

cool story....I've actually welded cast iron a lot, not talked about it....the weld will not break if the welder is good, in Cody's case, he has a great welder, so it will be fine. Cast aluminum is a bitch to weld, maybe you're thinking of that.....

Stop being a douche. I was asking a question and was looking for an answer. Not some smart ass responses from someone other than the vendor. I have experience welding, I have taken welding classes, and I know many people who have tried to weld cast iron and failed. I looked into having this exact process done to my own manifold in the past and was turned down by local welding shops. I was curious of the process that they used, not trying to cause trouble, I know it can be done but I also know it's not as easy as you are making it out to be. And also, stop being a douche.

Don't mind my rigging here, but it works. WHat I did was used hardpipe off the flange and welded it down near the steering shaft. Then I welded flexpipe to it. On the downpipe itself I then welded an elbow, that allowed the dump pipe flex section to slide over it, and then used the guientine clamp to secure it, and allow it to be removable. I then wrapped it all with header wrap, and spray painted it with the DEI wrap paint stuff as another layer of heat control.

Yes, while removable, I kept my permanently recirculated. I don't really care for the sound of an open dump pipe asI like toned/quiet exhaust setup on my cars. You don't even hear anything extra this way, helps keep it 'sleeper/oem' to a degree, which is my style.

Yes I have flex Pipe in that piece. I don't really have many pictures of it, as I fabbed it and installed it and called it a day.

On my example, the upper red part is hard pipe. cut at an angle, and welded to the flange. The green part is the flexible tubing that I got from JCwhitney (1.25 or 1.5" I can't recall). The flexible tubing then slides atop more hard tube (again in red at the bottom) where it recirculates back into the downpipe (secured via that guillotine clamp). Could I have fabbed it with all hard pipe? Sure...but the flex tube was available and easy to use. It's a MFer to weld with a mig (I'm also not a perfect welder) so just be careful with it, or have someone tig it. I had the mig super cold, and very fast to keep it from melting.

Anybody thought of doing the exact same thing (welding a flange for wastegate) into the turbo rear housing? gate is directly where the exhaust spins turbine so it would exhaust the not needed gas right there rather than way up in manifold? I am doing it this way to my RB20 turbo until i save and buy better manifold and turbo etc.

I like your work on the exhaust manifolds as well though, nice job

That's a ton of cash right now, and I'm not sure it would be worth it. Also, what us the short most reliable wastegate everyone if buying these days?

There's no reason to buy a brand new OEM manifold. BNIB OEM=/=USed. Have your Tomei fixed for $50. Easy day.

And extrude honing a stock manifold honestly is not worth it. You won't gain much response for the outrageous $500 price. You're better off honing your intake manifold for smoother air flow into your head.

External wastegate is the bomb. Had this setup on my 2871 bottom mount setup. Shits on internal gates all day long.

There's no reason to buy a brand new OEM manifold. BNIB OEM=/=USed. Have your Tomei fixed for $50. Easy day.

And extrude honing a stock manifold honestly is not worth it. You won't gain much response for the outrageous $500 price. You're better off honing your intake manifold for smoother air flow into your head.

External wastegate is the bomb. Had this setup on my 2871 bottom mount setup. Shits on internal gates all day long.

Yep that's some good advice right there. I've just always been a fan of cast manifolds from my vw days of boosting "inline" 6 cylinders. Never had a problem with cast manis. But most def, fuck spending all that money. I should just weld a tial mvs to my housing and call it good :) maybe get a gtx while I'm in there

Sure it seems expensive, but it is *the best* setup for the bottom mount GT and GTX turbos. The tubular manifolds are not built well enough (outside of a doc race maybe) to withstand the rigors of being in that spot. They really need better support structure to keep from cracking.

I went with the external for that reason as well. It ended up being cheaper than the tubular manifold, and hasn't given me an issue in years of abuse on track and street.

this is definitely great setup but to make the best of it
what turbo elbow will be best to use with welded flapper?

Is this bigmouth style, no divider with 3" pipe still good

or is this smaller pipe actually better after cutting off and closing that screamer tube http://www.racespecperformance.com/WebRoot/Eclipse/Shops/racespec/50A3/A002/B058/DF34/E1ED/0A33/6589/7721/200sxsc2.jpg

The greddy turbo elbow works best

Divided sections but flow back together

Welded screamer pipes are extremely loud, for those of you who might not know.

If you want your car to yell, "LOOK AT ME" and be super loud every time you floor it, go for it.

Thanks for your insight. I like the doc race manifold alot but already have the tomei that came on the car. Should have some cash to blow in a few weeks. Will see what I end up doing then.

I do have a greddy elbow I could slap on the car or sell if anyone wants it

I think my leak is coming from the Megan turbo elbow as it looks like the flange is warped. Would be nice if someone made a high quality vband setup. I love vbands

Vband is the way to go. My entire exhaust is V Band from the turbine out. Minus the T3 flange. That's a very annoying place for a vband.

got any pics of your setup? how are you liking the GTX? ive got the gt2860rs and thinking of upgrading to the new gtx wheel for faster spool. when do you hit full boost?

I'm actually on a GTX3076 .82. With no timing thrown at it I'm seeing 20psi at 4200.

I used to have this set up though on my 2871. That wasn't V Banded. Pain in my ass those 5 bolt turbo flanges were. Especially with the PBM flex cobra DP. That set up saw 1 bar at 3400, same timing as my current set up. Waiting to go E85 before we start advancing timing. Should bring spool down a few hundred rpm.

Right on sounds good! Thanks for the info! I'm curious to see what the 3076 puts down.

I use my car for mainly drifting and canyon so the quick spool is really nice. I'd like to be spooling around 3000-3200, if possible. I read a guy with a precision hitting like 30psi at 3200 or some shit.

On a setup like this, it should not matter where the wastegate outlet dumps back into the exhaust, correct? As far as AFR goes that is.. I want to plumb mine back in at my downpipe, but I put an aftermarket wideband detector there and want to know if I should put it downstream of that (or if it matters at all). Thanks.
