Evo 3 16g Install + Accessories

[Afizzle]

if you could go back and redo your 16g install what would you do to make it better

things im worried abut are the o2 and exhaust mani porting. i wanna get the nastiest meanest sound from the exhaust setup ill be running while also minimizing lag and getting the most horsepower

picked up a evo 3 16g in mint condition w/ a punishment racing o2 housing and hks external wastegate. i plan on taking off the hotside for an external wg and replacing with oem hotside for internal wg and am also wondering if the punishment racing o2 housing will need to be replaced. it ws previously on the turbo so i guess it works but i need the best o2 housing match up possible

supporting mods are dsm link v3, 1000cc injectors, Punishment FMIC, FP Exhaust mani, Megan DP, custom exhaust, and HKS Carbon Hi-Power Ti Muffler, Greddy Type S and Hallman Pro boost controller

what am I missing and how much should the o2 and exhaust mani be ported? I will be doing everything at the same time

It should be a breeze since you already have a fmic. That the biggest pain, installing a 16g with a stock smic.

Well that and broken exhaust bolts. If its never been apart you can guarantee some of them will break. So be ready for that.

Gasket match is ideal. Removing any edges and step downs. The 2g o2 can be opened up to nearly 3" if you have a true 3" dp. If not match it to the 2.5"

Vfaq has a great write up on porting the manifold.

I took it one step farther though and smoothed the entry point into the collector. There's a little material that can be removed from the area where the runners meet the collector. It creates a nice smooth slope down into the collector.

Make sure you get a nice j pipe. I had a crappy one on mine for awhile I hated it! Also keeping it externally gated keeps the creep down. But if I was going to run a 16g ever again. A nice j pipe to work with front mount intercooler is key. I ended up going with the ets j pipe. It was amazing!

OK... I've got a Big 16g a/r .70 with a FMIC and some ok piping.. has a recirculated 1g BOV and a O2 dump.. still seems to have a wicked creep on boost.. I've turned my manual boost controller down and it still hit's 15lbs and creeps into 17lbs.. hitting fuel cut at times in between creep too...

Now, I'm considering eliminating the O2 dump and recirculating through it & letting the BOV do it's JOB.
Clearly, I need a lot more fuel supporting the system & a few other odds & ends..

I just got the car a few weeks ago, and trying to learn what all is there and what isn't..
because clearly the kid that I got it from didn't build it & was a bad liar..

Anyways... are there any benefits to the O2 dump ? or is it just an annoying noise maker than never goes PShhhh-Psh-Pshhh-PSh-Psh...

 

[Afizzle]

thanks for the help

imgetting the 16g mitsu install kit so all gaskets should match fine. what bolts are talking about that are going to break? the car has zero rust on it so i might get lucky. might also throw pb blaster on the bolts the night before swapping.

can you link me the best place to find the ets J pipe that fits the 16? <3

is external wastegate really going to make the much of a difference? to me it just seems like chinese. all my buddies have all run internal.

Holy thread jack. Should probably start your own thread.

The exhaust manifold studs and the exhaust to turbo bolts are the usual culprits. I've had really good luck with the 02 bolts. And hell yea the pb blaster is a great idea. I don't think its necessarily the rust, but more of the heat that causes them to fail.

Whats your fmic set up look like? Im assuming your still on the t25?

But vrsf makes a very reasonably priced j-pipe.

Well its going to control boost better. No worries of boost creep. But there are tons of ways to improve the internal gate set up.

Hey, didn't me to jack you off

just asking questions about 16g supporting mods..

my bad

I think your confusing O2 dump with something else. An "open dump O2" is an O2 housing on the turbo itself that dumps wastegate exhaust. It makes a very loud growl when under boost. I think your referring to your BOV that is dumping to atmosphere. If so, there is absolutely zero benefits to venting over recirculating.

Stocker covered this well, but to add a few things:

The biggest reason for an "install kits" is for the oil and water lines. If you consider yourself pretty crafty with cars, you can install a 16g without an install kit. You basically just need stock gaskets, coolant hoses, an aftermarket feed line, and a modified oil drain. However, if you'd rather have a simple and quick solution for install (and can afford it) then by all means get an install kit. Here's one from Forced Performance.

Forced Performance Turbochargers: FP 16G Install Kit for 2G DSM

The J-pipe is going to depend on your intercooler setup. For instance, a Godspeed FMIC kit may require the J-pipe be angled to the passenger side. However, a Punishment FMIC kit requires the J-pipe to angle towards the driver side. So your current FMIC setup will determine which kind of J-pipe you need. Most "install kits" will included a J-pipe meant to be used with a SMIC, which is short and angles to the pass side.

External wastegates are great for holding boost rock solid. However, they are expensive and a bit overkill for most 16g setups. Like mentioned, there are other ways to eliminate boost creep with a 16g such as porting the wastegate hole and keeping exhaust pipe size reasonable. But my personal favorite solution to boost creep: Install supporting mods and crank up the boost.

for fmic im going with CX Racing core and custom alum piping. that being said whats the best order to handle the plumbing. should i install the turbo and fmic then go get the piping or is it possible to kinda line it up and pre install and go from there. im not good at fabbing but my buddy seems 100% confident i can save a lot of money by buying the core and making my own piping so i trusted him on it.

Oh and the exhaust is full 3" custom piping, one end a 2.5-3" DP, other end 3" inlet to 4" muffler tip.

so things i need to order:
MHI install kit
J Pipe
Fab up IC piping OR should i just buy a full kit?

 

[WES_393]

A full FMIC kit makes things much easier. It took me a few days, some welding, and quite a bit of extra $ to make my own piping and mounts with my Godspeed core. Then the crappy clamps and couplers kept blowing off and leaking. My Punishment kit took maybe an hour or two from start to finish and has never given me trouble. Punishment also uses a very decent CX Racing core with their kit. Comes with a J-pipe as well.

If you did find a different core you wanted to use, I'd still suggest a piping kit. But with the price difference between a quality piping kit and a full FMIC, I'd just go with a full FMIC kit.

[Afizzle]

okay coo man you da bomb thats what ill go with
was thinking punish or vrsf but i think punish will give that really FULL look on the front

anyone wanna see pics of the turbo and stuff?

only using the turbo from this set up. replacing hot side for oem 16g hotside for internal wastegate

got the turbo, HKS external wastegate, and punishment o2 for 200$

turbo has no play whatsoever and will make me very happys

Thanks again !

 

[Nico_]

great answer!

 

[Bud92gsx]

This should have a 2g emotocon next to it..

 

[4Lurker4]

Just a heads up, the turbo isn't an Evo III 16g it's a small 16g per the serial number.

 

[Afizzle]

same thing right?

if its a genuine small 16g then it came off of an evo 3 yes?

also punish FMIC ordered, tdo5h install kit ordered, 1000cc ordered, buying a chipped/DSMlink v3 ecu this week as soon as my buddy gets his aem in. trying to decide on a DP and muffler right now might just go with a full 3" thermal

gonna install everything at once, will this pose any problems?

soon as everythings on and the car is purring gonna order the LSD n strut bars along with stiffer springs and some struts. any suggestions from fwd owners on what to go with for stiffer suspension to lower spin and wheel hop

oh and what am i forgetting theres got to be something

 

[rcarbajal4]

If you want to eliminate wheel hop consider poly motor mounts.

 

[Afizzle]

If you want to eliminate wheel hop consider poly motor mounts.

okay thanks man

do you mean poly mounts themselves or poly inserts?

thanks again

 

[turbolover10]

IDK what was mentioned above but the first thing that pops in my head is properly porting the turbine housing so you wont have to worry about creep and it will match that nicely ported mani Also after the install make sure you do a PROPER BLT!

okay thanks man

do you mean poly mounts themselves or poly inserts?

thanks again

BOTH! You will need them

Front and rear inserts and driver/passenger solid mounts.

 

[Afizzle]

okay thanks man ill definitely look into that as soon as the turbo is hooked up and car is 100% happy

one more question, should i go with high z or low z injectors. would just like to get opinions before i buy the ones i have bookmarked. was set on 1000cc low z injectors from clinic because what ive read they have faster response times and shorter dead times but high z is what our car comes with from the factory and has better spray patterns right?

<3

 

[WES_393]

same thing right?

if its a genuine small 16g then it came off of an evo 3 yes?

No, there are 3 different 16g's. The small, big, and Evo 3. The small and big are typically good for 300-350hp. Big flows a tad more, small spools a bit faster. The Evo 3 16g has been pushed to over 400hp.

Nothing wrong with a small 16g though. I ran one for about a year and loved it. Its a potent little turbo.

 

[Afizzle]

well damn that kinda pisses me off. i only wanted 350 hp but sounds like i couldve goten it a lot easier with the evo 3

GRRR this is why i hate buying used shit...
