evo III big 16G or 20G turbo?

[erickeri]

Ok guys I'm doing my turbo set-up.. I have the t3/t4 turbo. It looks like it was bought from ebay.(JUNK). I don't know if I even want to waste my mine in doing the project. I was looking for a better turbo. I seen alot of people running the 16g and the 20g.

Which one should I go for. And I see them ebay. Are they the real turbo's or the fake shit.(KNOCK OFF'S)

Im going to run an FMIC, But the piping is 3". Is that to big or should I do a 2.5".?

When i go with a new set-up. whats the better exhaust manifold to run. 1g or 2g manifold.

EvoIII 16g or 20g depends on your hp goals and streetability you are looking for. The E16g will be better for street as you can hit full boost at lower rpms but the 20g will give more hp overall.

Most turbos on ebay are Chinese knockoffs so you would have to check the numbers on the turbo to see if they were true Mitsu turbos or just the knockoffs.

3" intercooler piping may contribute to slightly more turbo lag but more flow in higher rpms as compared to 2.5" piping. And it will just be a little harder to route it through your engine bay.

2g manifold is much better, less prone to cracking.

Damn, thanks alot for explaining that to me... Thank you.
Still thinking about that 20g...

What are your power/track goals and plans for future mods?

If you are wanting a good amount of power I would go with a 50 trim instead of the 20g. They will both spool the same but the 50 trim is capable of a little more power. And the 50 trim can be bought for less than a 20g.

You won't see any gain with 3' intercooler piping with these turbos over 2.5". If you are not going to go with a big turbo later like a gt35r or bigger for instance then I would just put 2.5" piping on it. The 2.5" piping is cheaper, lighter, easier to mount, and comes with most kits already. You won't see any loss with the 2.5" piping.

And as already said the 2g manifold is better because it is less prone to cracking and flows more.

i would go with a 50/trim....i have the evo3 16g ebay version...dont get me wrong its a great turbo(maybe i just got lucky?) but i will have a 60 trim this week !!

like everyone else said it depends on your power goals. and what kind of powerband you would like say for instance the evoIII will be very streetable as would a tdo5 20g. where as if you go with a 50 trim or a tdo6 20g you will have a turbo better suited for top end power and higher boost along with making more power in the end.

now with the 20g as i already stated ther are many variations and such but the two main ones are the tdo5 and the tdo6. the tdo5 has a smaller turbine wheel (spools quicker has good mid range power) and the tdo6 has a larger turbine wheel (spools a lil slower but hits hard and has good top end). now the problem with tdo5 20g's is the bigger compressor wheel will overflow the smaller turbine wheel in higher boost pressures and have a ton of back pressure because of that. meaning it will creep easily but that nothing a clipping of the turbine wheel matched with porting the housing won't cure.

as said before also a 50 trim can behad for cheaper (not to mention 20g's are just really expensive) and you can make a lil more power/boost more with a 50 trim.
so in the end it depends on what you will be doing with the car, future plans for the car and such. but take your time do your homework.

now as for me im running a tdo5 20g on my galant and i will be doing mainly auto x/roadrace with this car so the tdo5 is perfect for mid range as would an evoIII be. where as the tdo6 would be a lil laggy. and not to mention i bought it used for 400 and im runing and external o2 housing tial 38mm wastegate to try and help with the creep/backpressure. i am also running 2.5 ic piping with my car truely no need for 3 unless you have an mkIII supra with a 40r bolted to it and your boosting 40+ psi which none of the turbos talked about will reach effciently.

if you can go with an evoIII exhaust mani those flow even more than a 2g, or if you have the money go with a fp race mani from Forced Performance

You will need some supporting fuel mods for these turbos. Another thing to be aware of is that a bigger turbo can produce much more cfm. What I mean is at 16lbs your stock turbo has maxed out your fuel and with a 20g or 50trim you will max it out at 12-14lbs. A better fuel pump, fuel regulator, injectors, and some tuning would get you really far.

I offer you my bible Tech Guide: 2G 4G63t Upgrades - DSMtuners

 

[Sewey_GSX]

It really does depend on how you want your car to perform either on the street or on the tack.

With either turbo you will need to tune and upgrade your fuel management.

For the tune I would recommend DSMLink. A friend of mine uses Link and I myself will be picking it up as well.

* fill out your mod/car profile. *

there are a lot of things you should do before buying a bigger turbo.

Thought about a 18g, Might be the happy medium. FP has a group buy on them now.

We are running a EVO III big 16G W/EVO III O2 housing (both ported) and EVO ported exhaust mainfold, 2G MAF, 550's w/Walbro pump, P&P head w/ HKS cams & oversized S/S valves and Crowler springs plus a big SBR FMIC. Tuning with Apexi SAFC for now...put down 290hp to the wheels on awd dyno @ 18# boost. Very nice car on the street...extremly responsive...will break all 4 tires loose on a roll. Had it tuned at Extreme Motorsports in Odenton, MD and was told it was an easy 12 sec. car. If we upgraded to a header and DSM link we could expect ~350hp to the wheels. From what I have been told from several reputable DSM builders power above 350 is starting to get into the range of many parts power limit. Above this part will start to break and thee car looses it streetablilty...broken axles, rear, trans, etc. Our goal was to build a car between 300 & 350 hp since it was a daily driver for my son and this was the combo that came highy recomended. We will eventually go with DSM link and be done. Oh it did explode the stock 5-speed in 3rd gear ~18-20# boost beyond repair. We are now running a TRE Stage 2 trans w/ACT 2600 kit and Street light flywheel.

Add a little alcohol and turn the boost up if you like...the turbo can go in the mid-high 20's no problem with a built bottom end and is capable of nearly 400hp. But like I said 18-20# on pump gas on the street you won't be sorry with the Big16G...no lag here!

good luck,
Scott

this sounded like a good thread for me. ### im about to bolt up a 16g ### my 20g went out so we'll see how it goes an see which 1 i like better. the 20g put down 387awhp at 23psi. so well see what the 16g does.

 

[banishedmunk]

as far as turbo, you already got all the input you need. Now for that mani, def. 2g, Less cracking.

 

[Turb07]

+1 for the 2G or EVO 3 manifold!!

just my $.02

Turbo

 

[robinho609]

stay away from ebay and get ## 16G from slowboy racing

 

[JusMX141]

I'm a huge 20G fan. There are so many possibilities depending on the power you're looking to make- TD05H 20G, TD06/TD06H 20G, Frank 1 (46 trim comp; TD05H turbine), Frank 2 (46 trim comp; TD06 turbine), Frank 3 (54 trim comp; TD06 turbine), Frank 4 (60 trim comp; TD06 turbine), Frank 5 (60 trim comp; TD06H turbine).

sleeper or bastard 16g

 

[Paranormal]

1g AWD DSM full weight. Untouched evo3 16g. VPC/AFC, FIC 650's. 26x12x3 FMIC. Water/meth injection. 30 psi. Bone stock 6 bolt motor, with just BC 272 cams. Stock intake manifold. Other supporting mods.

This setup took me to 11.6@120 mph on pump gas/meth injection. Forget the 20g, get the evo3 16g
