I was planning to buy a 16g turbo but as soon as I was looking I notice there are a couple of them, the small 16g, big 16g and evo III 16g. What is the different between these or the others ones out there like the 20g or 50trim? I was looking on dsmparts.com is there another place where I can buy it somewhere else cheaper? How about eBay?
 
To help do a search on 16 turbos los of threads here, goals? Ebay look for a used one not the chinese stuff. There all good turbos, goals are up to you. I have the evo and love it for what my goals are for now. LOL
 
How can you tell from a cheap one to a small, big or evo3?

The Evo III 16G (TD05H-16G6) differs from the standard Big 16G (TD05H-16G) in a few different ways, first by the size of the inducer on the compressor.

The Big 16G has a 1.892" inducer whereas the Evo III has a 1.902" inducer. The exducer on their compressors is the same (2.680"). The Big 16G's max practical airflow is 445 CFM (~33 lb/min) and the Evo III's is 530 CFM (~40 lb/min). The Evo III uses a compressor wheel that is made from aluminum with thinner blades than a standard 16G and it uses an Inconel turbine wheel.

Both compressors are approximately a 50 trim (Big 16G being slightly lower, Evo III slightly higher). They use different compressor housings (obviously), but they have the same center section and turbine housing, and their turbines share the same dimensions (1.93" exducer and 2.20" inducer). They all have a very quick spool for how much power they are capable of making.

The 20G has a bigger inducer (2.07"), making it a 60 trim. A 20G is going to have a much slower spool than any of the 16Gs.

You can get an MHI 16G from most vendors. If you want to pick up one for cheap, keep an eye out for used ones in the classifieds, eBay, and craigslist. Just watch out for imitation Evo III 16G's, they are pretty common and for the most part are junk.
 
heres my small 16g on the left and evo3 16g on the right. the serial number is how you know what it is if the turbos look like this then there real

I'm looking for about 350hp. Which one is good and about how much is expected to pay for it, or do you have a place that you recommend?

Edit: What else is needed to put one of these bad boys on?

You're going to want to go with an evo III then. Are you staying on pump gas?

I'm not going to lie, things are going to have to come together pretty well to make 350 whp on pump gas with an Evo III. Look at the "dsm dyno challenge" under the members tab and sort it by turbo size "big 16G" and see what all the people who made at least 350 whp had done. I'm not saying you can't do it, but just be prepared to put in a lot of supporting mods.

IMO just avoid the big 16g. It isn't a bad turbo in any way but it spools at the same speed as an evo3 16g and flows 2lbs/min less with no appreciable difference in price. The small 16g on the other hand is also a great turbo which does flow less than the evo3 16g but also spools more quickly.

With a good setup the evo3 16g will spool fast enough to be very happy on the street but if you want to autocross then I would tend to prefer the small 16g or even a 14b though a 14b wont be capable of 350hp without a lot of money elsewhere in the car.
 
Welcome To Extreme PSI has the evo III for $560.00, thats the cheapest I've seen it brand new I believe. You could get by cheap and have a "like new" turbo for fairly cheap if you waited for one that was in need of a rebuild to show up on craigslist, try and get it for $100 or less and send it to MAP and have them rebuild it. They do full rebuilds on Mitsu turbos for $225, which includes cleaning, rebuild parts, and a balance.

It actually flows about 7 lb/min less, so worse than you thought.

So, I'm going to keep looking until I save up for that turbo. If I do not see anything before I buy a brand new one I am just going to get it from them. Thank you for the info.

Last question, with psi how can I know how many psi I am running and how can I raise and lower it? I need a boost controller right? Which will be better a manual or electronic and can I router the knobs to control the boost controller in the cabin near me while I drive?

You need a boost gauge and either boost controller would work manual or electric

Which is better the manual or electronic? What I want to do is to be able to change the psi while in the car so which one can do that for me?
 
The part number break down of the various MHI 16g:

The part number 9178-05200 tells us that this is a small 16G
If the part of the number after the hyphen were 04200 it would be a big 16G
04700 would be an evo3 16G. On the 16G turbos, you will notice that this 52, 47, or 42, is etched on the newer covers, older ones are stamped, and the rest of the number is cast on the housing.

Having owned all three variations of the Mitsubishi Heavy Industries, "MHI 16g turbos" (small 16g, large 16g, and the Evo3 16g), I felt I should add in my experiences with them...

Small 16g (Mitsu part number 9178-05200) was my first turbo upgrade on my 94... IMO this turbo packed the hardest punch and offered the best in spool time on my stock 94's 2.0L 7-bolt. This turbo is and always will be what I'd recommend to anyone considering getting a "16g" series turbo for their DSM.

Big 16g (Mitsu part number 9178-04200) this turbo didn't seem to have the same initial punch that the small 16g did. The power band of this turbo seemed to cover the upper RPMs adequately. It's spool time was noticeably greater then the 16g.

Evo III (Mitsu part number 9178-04700) this turbo was the worst out of the 3 IMO... Significant delay in building boost and power band seemed to move to only the upper RPMs. Driving on this turbo out of boost was unbearable IMO. Once this thing spooled, it pulled pretty good, but by that time I was already tach'd out. I would recommend going with a TD-05 20g before I would go with an Evo III ANY DAY... I've owned a 20g that had better street manners then my Evo III did.

Ultimately it really boils down to what you want to do with the car, like others have mentioned. For 350hp, I'd ask yourself what other mods are needed in order to get you there first. The choice of 'what 16g to get' should be your last concern towards that goal. That is unless you want to melt some pistons first ;)

Last, I would stay FAR AWAY from the "Evo 3 GT" Turbo... These will have the "Evo 3 GT" cast into the compressor housing where the MHI turbos have the part numbers etched/stamped. These are total junk :notgood:

Hope this helps

So, for street driving the small 16g is good enough. I plan on going to the tracks every once in a while. I like my car to get up and go especially in the streets. My main concern I don't want to get the small 16g and then a week or month later, I want to upgrade. I want to upgrade once and be satisfy with that. I am aiming for 300 to 350 and then I'm good with that because it's my DD for now.
