Ordering evo3 16g: different ones?

[1998gstspyder]

I was going to order my evo 3 16g from forcedperformance.net for a few reasons:

1. cheapest price
2. they port/clip
3. cheap price for install kit

until a friend told me that evo 3 16g can differ..is this true? i mean other than the knock off GT or the chinese ones with the blue cap...can it be a geunine mhi evo 3 16g turbo but be rated at a different hp from another geunine mhi evo 3 16g? for example buying it from slowboy vs forced performance.

Those turbos are identical except for the fact that FP does an incredible job with clipping and porting. One look at their ported turbos will tell you that they're works of art. The fact that SBR made 400 WHP doesn't mean it's different. Only the new generation twin scroll 10cm turbos for the EVO IX's are different (and pretty serious), but they don't fit our motors.

If you planned to buy from FP, go ahead and do so. They're the finest turbo vendor out there for a reason.

Hope that helps,

Andy

FP definately makes my favorite turbos, their price reflects it

Is there a reason why you want to get your turbo clipped??

 

[TSIMonsteR]

Gives a little more top end if it's clipped, correct?

What is clipping?

Clipping is the technique of cutting away some of the material on the fins of the impeller wheel of the turbocharger. In other words, to 'clip' a turbo is to make the fins in the exhaust path smaller. The cut is usually done at an angle of between 10 and 20 degrees - the bigger the angle, the more material is removed from the fins.

This may seem like a dumb thing to do, since smaller fins mean that the exhaust gases will impart less force to the turbine wheel and consequently increase turbo lag. This is true, but the benefit of clipping is found in the high RPM range of the motor. At higher RPMs, the turbo may have already surpassed the required user-set boost levels and is not contributing to engine power.

Since the impeller wheel in the exhaust stream partially blocks the exhaust gas flow (by design), it can act as a significant restriction at high RPMs, when the exhaust flow rate is highest. Clipping the turbo reduces this restriction and allows more air to flow past the turbo wheel at high RPMs, thereby improving airflow through the engine and increasing top-end response.


"Turbine wheel clipping: DON'T. For a slight increase in output, you sacrifice the turbo efficiency greatly. Clipping the turbine wheel is to have a little bit of less back pressure and more flow on the top end at the expense of turbo fall into a smaller efficiency island. In another word, the turbo will spool slower and have peaky power band. Clipping is not necesarry unless racing is the turbos primary purpose."

wow, nice post. Did you type all of that, or did you copy and paste it? either way, I'll feel smarter from reading it. Rep points for you

 

[cumpersgsx]

That answered my question...i was just about to post...thanks

The top part is from www.vfaq.com, the bottom part in "xxx" is from some turbo maker site that I found, I can't find it now.

I have a SlowBoy EIIIB16G with 17,000 mile; all is well. (stock boost, for now)

 

[TSIMonsteR]

The MHI E316g is the same from all vendors, it just depends on the options you pick. Definately get it ported, clipping is up to you

 

[1998gstspyder]

nice, ill save 75 dollars by not clipping it, i just wanted to because i want to max out the evo 3 16g and get everything out of it... i would have to have more of a lag, but then again, with fwd, lag can be a good thing, plus top end is mostly what ill need since bottom end ill be loosing traction anyway. nonetheless, i wont get it clipped

If you don't want to get it ported and don't want boost creep, get it from Dejonpowerhouse.com and ask them to do the "not-divided" mod. They say it helps eliminate boost creep.

I bought the evo3 GT from turbochargers.com and got it ported by my shop and I'm hitting 17psi at 3200, that holds till redline. This turbo is nothing to joke about, I think that its a shame the quality of the turbo is slandered just because word of mouth. I'd definately recommend looking into one. www.turbochargers.com

I would suggest getting your EVO III 16G from Turbochargers.com (whether it be the GT or the MHI). Even including shipping, they have the cheapest price of any vendor I've seen.

 

[JayRolla]

But still for not much more you can get a real mitsubishi turbo, I would not save a couple of bucks to take a chance to not buy mitsubishi. Mine was ported my SBR and I considered it a work of art also. Even my mechanic was surprised how good of a job they did(he dont like SBR to much). I have no creep at all and a full 3"exhaust.

I got mine there. The MHI version and its legit. Ill update on once its installed.

I hate to be a jerk but he just copied that from: http://www.turborx7.com/turboinfo.html

I'm just jealous I guess >=)

I got my E316G from turbochargers.com. Came fast works great. I'm only running 8 lbs on a 1G manifold and a 3" turboback with ported O2 housing. (Still need to upgrade my fuel system but the 14b that was on there blew...) The exhaust housing is unported but I do not creep. I figure that may change when I upgrade the EM, but right now I have no problems.

None the less he answered the question perfect and he never said it was his words. He even put on a later post it was not his quote.

 

[siceclipse]

i got a second-hand MHI unit originaly from FP and BOY does it look amazing.

Not only that but with a the port job they did it can hold 7psi all the way to redline if i choose with no creep.

Forced Performance = second to none

 

[MyBeatGSX]

^Do you have any pictures of it you can post up?

I ordered mine from extremepsi.com, it was cheaper than both the MHI and the China GT from turbochargers.com.

Do not get it clipped, it hurts more than it helps. Do NOT get it undivided, this helps nothing and hurts everything. And be careful on the porting job, boost creep eliminating port jobs hurt turbine flow, the more aggresive the port job and the better it resists creep, the worse the turbine flow will be.

Yup, that's the link. Thanks for searching it for me, my window closed before I could copy the link.

Please explain.
