EvoIII 16g OR 50 Trim

[99gsx0221]

i've been debating between these 2 turbos for a while now. I'm going to be using this car as a DD and occasionally at the track. Supporting Mods will be a FULL fuel system, exhaust & DP, BOV, and a FMIC. Eventually i will be looking at pistons, Cams, and a DSM link.

Which turbo would you guys say is the best choice for my situation?

 

[brute]

50-trim. Maybe bigger. Possibly a GT30... That's only if you go through with the internals.

 

[nightspeed87]

what are full spool rpms, and the max efficient boost that can be ran on a 50 trim, and what general injector sizes are good to support the potiential of that turbo.?

 

[Jeff822]

What are some of your HP goals, track time goals, etc? A good bang for the buck 50 trim would be the FP green, another good turbo that has proven itself its the tdo6 20g you may also want to check that out i have heard really good things about it and im sure others here would vouch for that turbo also.

 

[YiNYaNg]

Get the bigger

 

[nightspeed87]

if I wanted to stop at 350whp on pump gas dd, would I even need to look at something like a 20g or any 50trims or anything, or would you guys recommend I just run a 16g for that? I still want decent spool times, thats why I didnt really look too much at the 20g, ( I wont ever rev past 7k so I dont need a lot of crazy top end power )

Ball bearing 50-trim
Full spool: 3800-4000rpm
Max hp: around 450
Suggested injectors: 850cc's

Evo III 16G
Full spool: 3100-3400rpm
Max hp: around 380-400
Suggested injectors: 650cc's

is that wheel hp estimates because I didnt know you could make 400whp on a 16g...
If so then i should just go with the super16g then huh, probably much cheaper too...
Like I said 350 is quite enough for me... Both of them have good spool from the times you listed, thanks man...

350whp goal = the mighty EVOIII!
350+whp goal = fity trim

very simple math dainel son

 

[brute]

The average DSMer will NOT see 400whp on the Evo 16g. This number was achieved by Slowboy. And they basically just bolted it up to their race car. Like I said, the average DSMer won't see these numbers because Slowboy's mod list is extensive, to say the least. Here's their dyno graph:

Quote from Slowboy:

Please note that SBR recommends this turbo if you are looking to make between 280 and 380 streetable horsepower. Above 380 wheel horsepower, your going to be running a lot of boost and some excellent fuel to sustain the power numbers without hurting the engine.

I think you should get a 20g, personally.
The majority of evoIII owners have not even broken 300hp with their turbos, yet all of the fast times are wil evoIII's with the 50-trims all considerably slower and behind in track times.

When I do my turbo upgrade, I might stick to the evoIII 16g just cause I like a fast spool, but if I was really serious about it I'd get a 20g over a 50 trim anyday.

 

[DGajre777]

A Dual Ball bearing PTE 50 trim spools just as fast as the EVO III 16G turbo.

EDIT: Close enough.

 

[Blackmitzu]

I have a precision sc 50 turbo and it is perfect for a dd that ocasionally sees the track. I would get the 50 Trim.

 

[crunchymilk]

I would say the 50 trim. You can run less boost for the same power. I've ran the evo3 for a while, wish I would have gone 50

Very good advice actually!

I've never heard that before, could you elaborate or provide reference please?

A Dual Ball bearing PTE 50 trim spools just as fast as the EVO III 16G turbo.

I wouldn't say as fast, but very very comparable.

People typically report 20+psi (3rd gear pulls) around the 3500-3800 rpm range mods/tune dependant obviously.

Ive seen E316G owners state anywhere from 3200-3500 using the same standard. Once again the specific mods and tune apply.

 

[dr1ftx3]

If you really don't plan on goin past 350, then stick to the evo 3. You can find them for half the price of 50 trim's and they are overall great turbo's. Plus the if quick spool is what you're looking for then this is the one for you.

It is not exactly the same, but compared to a regular non-ball bearing 50 trim, the BB spools fast.

With the BB5031, the sucker spooled just like an e316G

EVO III 16G Turbo at 21psi - 3500 rpm
SBR G50 Trim at 21 psi - 4100 rpm
PTE Dual BB at 21 psi - 3800 rpm

Spool up on 2.0L with mild mods
EVO3-16G - 2900 RPM
5031RE - 3200 RPM (Dual ball bearing 50 trim)
5031E - 3500 RPM (Non-ball bearing 50 trim)

hmmm.... The only reason i was leaning away from the evo3 is because seems everyone has it.... ( But then theres probably a reason why everyone has it huh )
Like i said i dont want to go past 350whp because thats when other reliability issues come up ( especially since my car is a dd ) The 20g sounds like it would spool too slow, and exceed my goals ... ( Keep in mind im a fwd so therefore the quickest spool isnt always the best for my car... ) The 50trim sounds in the league with the 20g... What about t3/t4 set ups? ( Kind of pricey huh. ) Whats the real benefit/ cons of those?
And also what about the 18g, i never hear too much talk on those... From what Ive heard there pretty much 16gs with a bigger compresser? ( So it basically to me sounds like a slower spooling 16g with slightly higher top end power...? )

 

[99gsx0221]

im basically looking to hit any 12's ... wether its High-Medium-Low. I believe i could do that with the evo3 or the 50 trim with the mods i have, but then again maybe not..

 

[andymoraitis]

I hit mid 12's on a 2.0, stock cams, sidemount and Big 16G. It's not always about the turbo, but the tune. Having run both a 16G and a 50 trim, I prefer the 50 trim for it's friendliness to pump gas, cooler intake charge temps and better top end. Either one will do fine, just make sure that you have the right fuel setup and strong tune. If you can drive reasonably well, it only takes 104 traps for a GSX to run 12's.

I'd also recommend at least 650's for either of those turbos. Even the EVO III will need them if you plan to max it out.

Hope that helps,

Andy

 

[99gsx0221]

yes i have 650's, i have 650cc injectors, walbaro 255 fuel pump, safcII controller for my fuel system. I believe that i will have a right tune as well. Right now im leaning toward the 50 trim, because i dont think i will get bored with it

 

[want_a_gsx]

Ball bearing 50-trim
Full spool: 3800-4000rpm

My 14B
Full Spool: 5k rpm!!!

something is definitely wrong

 

[JayRolla]

If you dont want to go over 350whp than the evo3 will be fine. You will have a lot of fun getting there with it though. But on the other end like Andy said the 50 trim is much more pump gas friendly and you will be able to hit your 350whp mark easier and take it further because once you hit your goal you will always want more. Atleast thats how it is with me and the dsmer's I know.
