16g differences

[Dual-Tipped]

what is the difference between big 16g's small 16g's and evo 3 16g's and is there any visual difference? a guy I know is selling a new one for 600 canadian dollars so I thought sure why not. but I would also like to know what I am buying too.

You have to measure the compressor wheel. no easy task to do quickly.

If you look @ this pic you can see the visual differences between the 3- Evo III being the best and flowing more CFM than the others..I would just buy the EVO III from SlowBoy and forget that guy..Its about the same price,your guranteed that your not gonna get screwed,as well that your getting a genuine EVO turbine,plus you can have them port and clip it if wish so before it is shipped.

Here is all the info you need to see the world of differences-
EvoIII= Stiffer WG spring-2lbs lighter housing-2.5" outlet v.s 2"-Comp wheel is bigger and lighter- info @ http://www.slowboyracing.com/Mitsubishi Turbos/EVO 16g/Wheel_comparison.html

Does anyon show a pic of the compressor wheel on the evo III and the big 16 g? Ive hot a ported b16g and the evoIII exhaust side doesnt impress me at all.

My bad, so there is only 10 thou diff between the compressor inducer on the evo III and the big 16g? So a good port job and larger wg flapper and you will have a b16g that is comparable to an evo III. Now Im glad I didnt waste the $ on the evo turbo. The big16g has now become a break in turbo with 50 trim in the near future. Anyone want to buy a b16g ported with 1200 miles and no shaft play? alway timed and exhaust almost looks like evo III.

 

[Jdmturbo]

To me its worth the extra $10 for the EVO III- price @ Slowboy site...considering the porting will run you at least 5 times that and the bigger flapper itself will probably cost that too(not including install)..not to mention it is lighter,hence the faster spool up with other factors involved.

EVO III=$569
Big16g=$559 porting $50-75 34mm wg flapper on clearence $20 @Slowboy..but needs install (??)

You decide~

 

[92awddsm]

Me=b16g Exhaust housing= porting to 7 cm, bell port on outlet to 2.5, wg hole opened, everthing matches the evoIII o2 gasket done by me with no boost creep so no need for 34mm wg flapper.
compressor=ported and radiused entry and outlet ported to 1.5" blended, done by me also.
Turbo from some shop in RI(cant remember name right now) = $425 shipped brand new.
Now why would I buy a evoIII 16g for over $500?

I don't think that porting really gives you any more power, anyway. All the exhaust still has to go through the same sized hole to get to the turbine, so what good will porting before the turbine do?

I currently have the fastest mph out there for a big 16G. It is an Evo III big 16G with absolutely no porting, and no clip. 118mph in a 3315lb full-weight 2G.

I just ran an 11.954 @115.9mph with a 1.71 60-ft last night.

The Evo III 16G compressor wheel has a smaller shank than the big 16G. It also has thinner blades, and the larger inducer diameter. All of this adds up to a hell of alot more compressor inlet area than the diameter difference alone would indicate. It turns out that the Evo III 16G is really closer to an 18G than it is to a big 16G in terms of compressor inlet area. It is a bit more than halfway between those two turbos.

Porting before the turbine does help. Thats like saying that porting a head with stock valves is pointless because it still goes thru the same size hole. You can port the step out of the tubine housing which increases velocity which spools the turbo quicker and more efficient. Same goes for opening the passage as much as you can safely without gettin too thin. That will give slightly more volume which helps flow more exhaust. Congrats on the timeslips but that doesnt make you an expert on porting or what pro/cons there are with a ported turbine housing.

 

[ShapeGSX]

So please do quantify the benefit. How much horsepower are we talking?

And how can making a diameter larger increase the velocity? It will decrease the velocity if anything.

 

[92awddsm]

I never said making it larger wuold increase velocity and there is no given amount of power in porting. Every car will respond differantly to changes.

It can be concluded that the EVO turbo flows that best and makes more power than than the 16G.

is the EVO III just a bolt on?

 

[TheTSiGuy]

is the EVO III just a bolt on?

For us 1g folks. Yes. Although the ex. manifold and o2 housing are reccomended.

 

[mitsuclipsegsx]

what about 2g's
