Difference between turbos

[steviek]

Well I have noticed that the evo 3 makes full boost extremely quickly it seems to me like its either full on or full off. If I try to keep low by peddling the throttle it just fluctuates up and down tremendously depending on whether I am laying off or putting down on the pedal. I wouldn't be too worried about breaking traction up in the higher gears with it but first and second may be a problem the spool up time on my car with a 3' turboback and the rest of my mods is like nothing It is almost identicle to the t-25 just way more top end power... On the other hand I'm pretty sure the big 16g will act quite similarly but I have no experience with it.

i can already break lose in 2nd gear with my t-2small (not just cherp, full burnout) at only 15psi and stock injectors... maybe i should stick to the fp green then? i just cant stand the high end (or lack their of : ) with the t-25... and dont have the money for the green, not to mention, its WAY overkill...

is their a way to tell the difference between the Evo3 16g and Big 16g visually without pulling the compressor housing off? i'm shopping around right now and see TONS of EVOIII Big 16g's but their is no such turbo, its eaither a Big 16g, or an EVOIII 16g, so is their something visually different?

yes the big 16g uses a dark material on the outlet side while the evo3 uses a lighter colour ... look

edit
how will going with a fp green which delivers more power save you from burning out because you may not loose traction right away when it starts to spool but you will sure as hell lose it when it hits full boost I guess I'm just saying its a matter of time...

also people probably just say "big" in the title so it gets more hits or something, its redundant I know but it means nothing it will be just the regular evo3.

i think the picture of the EVO3 was taken with a flash, and the one of the B16g wasnt... they look the same to me (I COULD VERY WELL BE WRONG)

I would only run enough boost to make about 380whp, and since lagg time is longer, i would be able to hold more traction... i think? (i'm probably to ONLY person in the world worried that my turbo will spool to FAST )

actually that makes sense to me but it is a very expensive turbo and setup to only make as much horsepower as something much cheaper.

and no man they really are different colours im 98% sure I think the material change is one of the reasons the evo3 is lighter.

well, i was going for that turbo because i was on the high way to an AWD conversion and a stroker, but then i had to quit my job (damn school!) and dont make NEAR the money i used to, so that project was shot, then i was just accustomed to it, and hopefully my car will one day see a stoker motor, and a green turbo, but not anytime soon, and i've decided to go with one of the 16g's.

and awesome, so the evo3 has a lighter color compressor (cold side) housing then the B16g? correct? thats GREAT news!

Have you done any traction mods to help with the burning out? Going with the FP Green will only make matters worse once full boost hits, you'll be burning them all the way through 3rd and into 4th instead of 1st and 2nd, plus only using half of the turbo? That's a complete waste of money IMHO.

Get the EvoIII, then some traction upgrades, and THEN see where you're sitting as to where you should go next.

i realize that the FP green would be EXPENSIVE, but i wouldnt be wasting my money on account of future (far, but still their) mods, as of this point in time, i do not have the money to purchase the FP green, and cant stand the t-25 anymore. so this is how the whole debate got started. lol but you guys have really helped out ALOT! and i have decided to go with the EvoIII 16g with the 34mm wastegate mod, unless someone knows if the flapper is the same size as the 31mm std wastegate, so i can save the $60 and port it myself.

Man I missed a lot here...but I remember talking to a guy on the phone at RRE and he said the differance between the Big 16G and the EVO 3 was mainly in the hot side...it is a little bigger I think he said and it is made of a slightly differant metal and is lighter than the regular 16G

if they are truely made of a different metal, then it is true that the Evo3 is a lighter color then the b16g! for more info!

20g it up! Screw messing with all that 16g crap. You can make 400 ponies on the 20g and have a little room for some more at a later time.

[Black99GST]

well i was thinking about getting the 16g, then making my own "bastered 20g" that slowboyracing makes. but i need to know what core they use. also, the compressor cover on the Evo3 is thinner/lighter then the b16g, and i dont know of the 20g blades will fit into the evo3 housing as opposed to the b16g... anyone?

[gthompson97]

I think you're gonna get in over your head with tearing down these turbos. Just buy the one you want, instead of throwing a bunch of different parts together, because the chances of it working correctly for a long time are slim-to-none. First time turbo rebuilders always tend to screw something up.

[defiancy]

I agree with gthompson97.

But I think you should look at it from a more realistic stand point. Not saying that the 16g doesn't make good power. For what your power goals seem to be, I think the 20g would be more a proper fit. The 20g can make about 380-400 easy with proper mods and a good tune.

To do that with a 16g evo 3 or not is gonna require a significant amount of tuning and tweaking your setup as was said above.

If you really have your heart set on the big 16g than go for it, just know that anything over 350 is really not very realistic for the turbo. Crap 350 is pretty good for that turbo.

I just looked at tuners and I see only two or three cars on there with a 16g making 350, most are making less on a 16g.

Well about losing traction my evo3 hits like a mack truck and im only running 15psi. I couldnt imagine having fwd thats why i got the GSX
