What kind of psi are we talking about in stock form ??? This is the stock turbo of an '03 evo. is this good for an ls or h23 motor ??


If you guyz had links to Honda projects (b or h series) using this turbo I would apreciate.

in stock form for the EVO i am almost positive they run like 18-19 psi on that turbo and have seen a couple round here turn the boost up from that, so im sure it can go a bit higher than that.


i have seen a couple turbo honda projects with this turbo and they have made great power, from riding in a couple evo's the turbos seem to make boost damn quick too

 

If it's off the new EVO's, then it's good for 400whp (at least on a 2.0). The EVOs run around 18-19psi stock, so you'll need a well built motor to take advantage of this turbo.

 

The evo's do run that much PEAK boost stock (19.5) right when a stock evo hits that boost level it will drop dramatically, but this is controller by the evo's boost solenoid and ECU, not the wastegate spring.

Im willing to bet the spring in the wastegate is at about 13-15psi

And many evo owners are doing 400+ on stock turbo

 

Well I am not looking at a built motor or anything that serious... Any way to lower the boost level to a safer 10-11psi ???

Do you think thye sell springs for that.


BTW: I am building a dayly driver, what's important for me is...

GAS MILEAGE ( I will drive this car 25+k miles a years and most of that will be road trips etc...
My buddy gets 30+ MPG on his boosted gsr, I want similar results.

 

Yea, I bet you can fit a 14b or 16g wastegate on there. 16g is like 11-12 and 14b is around 9-10.

It would just take some modification.

 

So if I keep thye stock wastegate (insnt my turbo a 16g?) I'll be running 12 psi ?...

Why doesnt the evo run 12 psi if they 16g wastegate is set a 12psi ?

Because it is electronically controlled by the ECU through a boost solenoid.

But if you run it with the wastegate vacuum line disconnected, it'll run off the spring rate.

 

I am not sure if the EVO is the same as a regular 16g. There are many varients of the same turbo. The evo turbo is a Big 16g.

 

this turbo is totally backwards of what the dsm tubos are, look it even sits backwards, these are tiwn scroll turbos designed to let the evo engine spool it faster, just like the srt04 has a twin scroll 15g turbo. These turbos CAN run up to 27-28 psi, but youll be risking it big time with it, you might blow the turbo.Your engine wont take those kind of boost pressures though. but the stock evo motors handle it no problem.

You're thinking of the B16g's that fit on regular DSMs. This is the EVO8 turbo, with twin scroll housing. It's completely different from the old MHI 16G variants.

 

I pulled this sucka out of the car myself So I know it's an OEM EVO8 turbo setup(I also have the downpipe +cat + catback.

Could I just buy a spring that will limit the boost to SAY.... 10psi ??...

 

just eliminate the internal wastegate and run and external wastegate.

Should be easy enough.

Good turbo though..

 

FORGE makes an aftermarket wastegate will differnt springs.

we can get it for you here at WORKS. Also consider the EVO MR 10.5cm hotside. big improvement over the stock one

 

yeah definitly the best big 16g yet. Flows the most cfm compared to the older 16g's, i think the shaft is titanium which i suppose is to aid in spool up as well as the twin scroll design. You will need a custom manifold if you want to keep it twin scroll, and it is aliitle tricky to run an external on it because in stock form the o2 housing has two ports for wastegate. One is for the cylinders 1 and 4 and the other is for cylinders 2 and 3 or it might be another variation, but the stock manifold is designed with two cylinders entering the exhaust side of the turbo at a time. I have a evo viii 16g for sale if anyone wants, to make offers on it

The only time you're using more gasoline than a stock motor is when you're in possitive boost. Drive it like you're dad (rather, a typical 45 yr old) would, and you'll never see boost. As for the wastegate, either get a manifold with an external wastegate, or buy an adjustable wastegate actuator off of ebay new or off any junkyard turbo (most of them are 6-10 psi stock). Keep in mind, with an external WG you'll need to rig it so the stock WG flapper stays wedged shut.

 

Dude, the turbo is a big 16G, to who ever said it wasn't or said something like I was thinking backwards. I have just about every 16G laying around my house right now. The only one I don't have is the EVO8, but I have seen a few of them in person, and they look kinda goofy in comparison. Maybe I will make another hybrid with an evo 8 some day.

Right now I am running a super 16g (hot)/ 14B center section/ big 16g wheel/regular 16g housing

HOW MUCH AM I LOOKING AT FOR A 10 PSI SPRING ? I'm not really looking for an external wastegate setup but let me know how much anyway.

some advice... sell that thing and buy a T3 based turbo. First you'll have to make a custom manifold (it's twin scroll and has a gay flange not like older mitsu turbos). Also, I've used every common mitsu turbo and I can tell you a nice t3/t4 is a lot better.... SELL IT

 

That turbo is the TD05HR-16G6-9.8T. There is a few guys on the AEM EMS forums that have put down over 400whp on a stock turbo. Thats 400whp on a AWD car - which is realy awesome power - they have big drivetrain loss remember.

Its a kickass turbo. It would be an awesome turbo on our honda motors.

liam

some more geek tech about the turbo...

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">Turbo = TD05HR-16G6-9.8T (GSR / USDM) TD05HRA-16G6-9.8T (RS/RS2)
Nozzle Area (cm2) = 9.8
Turbine = USDM EVO 8 & JDM GSR =Inconel (steel alloy), RS/Rs2=Titanium alloy.
Compressor = Aluminium, 68mm wide

Evolution MR aka "8.5"
GSR = TD05HR-16G6-10.5T or TD05HRA-16G6-10.5T (Ti Alloy option)
RS = 6MT:TD05HRA-16G6-10.5T or 5MT:TD05HRA-16G6-9.8T

Nozzle Area (cm2) = 10.5 or 9.8(RS-5speed)
Compressor = Aluminium, 68mm wide

All Evo 4-8 Turbos are twin scroll designs meaning that the engines exhaust is divided into two channels. As the engine exhausts in pulses.. its supposed to result in quicker spooling. From the Evo 4 onwards, the Turbo spins in the opposite direction, i.e. Anticlockwise (hence the R in the turbo name). The Titanium Alumnide alloy used in the RS/RS2 and some GSRS (factory option) has less inertia and thus spins up around 500 rpm sooner. These Titanium turbos can be indentified by the A in their name.</TD></TR></TABLE>

The best thing to do is find out if the EVO turbos internal wastegate actuator line has a restrictor pill in it to raise the boost or if it is ECU controlled somehow. A restrictor pill is just a piece of plastic or metal with the center drilled out to a certain diameter and it is placed inside the vacuum line that goes from the wastegate actuator to a good boost source, such as the compressor outlet. The purpose of a restrictor pill is to limit the amount of boost going from the boost source to the wastegate actuator.

Either way it shouldn't matter if the EVO controls the turbo with pills or the ECU. If you take both of those out of the turbo system, then you are running at the actuator arms rated PSI level. All you have to do then is run a vacuum line from your boost source to the WG actuator.

EDIT: I dont think you'd want to run the turbo without the WG actuator being hooked up to a boost source. If you do this the actuator will not open the WG flapper. When the WG flapper doesn't open all the exhaust gas go through the turbine and your boost will be unregulated.

The WG actuator has a hose going to a boost source already... but also has another hose going to some sensor.

So basically I just plug the hose going to the sensor and then I'm running on the spring ?

I'm keeping this turbo, even if it means having a flange welded on a t3-t4 header. The evo's come with an awsome turbo from the factory taht are built to last a LONG time. On top of taht lots of evo owners upgrade so if I need a replacement i the future, it wont be 2 hard to find. While all the sheep are fighting on ebay for a t3/t4 the dsm turbos are not getting as much hype so it's easier to find a GOOD ONE for a GOOD price.

OH.... did I say.... This turbo is not costing me a dang penny.. I bought a wrecked evo from my local auction and have I have this leftover(my heart could not part with it)

besides, if I go h23 I can used the evo manifold will little modification. If I go b18, there are companies that make dsm flanged headers.

BTW.. how is this flange different from an older dsm turbo.

 

trust me bro... sell that on ebay. You will make more than enough to buy a nice t3/t4 (which is obviously better because thats what they upgrade to). The old school flange was a rectangle with a circle in the middle... those twin scrolls use a square with 2 triangles or 2 ports.... They usually make manifolds for the older turbos... That's funny u say that people are sleeping on mitsu turbos... the lack of good 14bs and sky high price (for what reason I do not know) of 16gs made me switch to garretts.
