Is this a 16g or a 14b

[N2O_ZX2]

Well to start off, this is my first post on this site. I drive a 98 Ford ZX2 2.0 DOHC on nitrous, with lots of other work done to it. Its pushing about 205hp at the wheels, but Im kinda bored with it now so I bought a new project yesterday. My new project car is a White 1991 Eagle Talon TSi AWD manual. So far its got an intake, 3'' exhaust, apexi bov, turbo xs mbc, uicp, licp, 6 puck clutch, tenso racing seats, Apexi turbo timer, autometer boost and a/f gauge, and a few other things. I bought it for $800 with a rebuilt motor with 50k on it and a spare motor, 2 turbos like these, 2 IM's, new cam position sensor, new stock clutch, 2 other TB's, and a few other parts. The question I have is if this turbo is a 16g or a 14b? I have searched around a lot, and I believe its a 16g due to the compressor wheel, but I cant be sure, and am looking for expert advice. Well, what do you guys think? Thanks.

I believe that it's an Evo 3 16G turbo. Great find.

Here's more info to help you out in the future


MHI Turbo's

If the last 3 or 4 digits are

49178 - 01420 = Big 16G
49178 - 01520 = Small 16G
49178 - 01470 = Evo III 16G

 

[blkwidow]

Hmmmm........ send it to me and I'll check it out for you

 

[N2O_ZX2]

Thats sick! So in that case I have TWO EVO III turbos just sitting on my desk. My new TSi has an EVO III turbo right now too. Oh man I love this car! The $800 part makes it even better! The turbo i just posted pics of has really really bad shaft play side to side. One more thing, which of those three turbos is the best?

Damn, who's dick do ya have to suck to get a DSM like that for $800?

 

[N2O_ZX2]

Yea the only problem it has is that it jumps timing. I think (only after reading around this site) that its caused by a bad auto tensioner, but I haven't had time to investigate it further. If its a bent valve or something, at least I have a spare engine.

Properly Tuned and with Supporting Mods = Evo 3 16G

I believe Small 16G is a little bit quicker in spool.

First off, thats a hell of a buy for $800! Congrats and welcome to the club. Anyway, if its the stock turbo, its a 14b. Theres no way to tell just by looking at the turbo itself since both 14b's and 16g's use the same compressor housing. You have to take the intake off and actually look inside at the compressor wheel to know for sure. The difference is the wheel.

 

[Black94DSM]

Wow that Evo III looks like it got hungry one day. Look at the compressor wheel, not much left around the edges.

Anyways good deal with getting everything for 800 bucks.

 

[blkwidow]

Wow, thats a good buy. I bought a 1991 GST for $400. The sad part was the compression test. 00. 60.00.100. The thing actually started though. oh well, sold it for $500 14B and a throttle body, plus half off on anything i need. Need anyone to take that EVO III turbo off your hands?

Wrong! You can tell just by looking at the serial number on the compressor wheel housing.

Please note that the serials above ONLY apply if someone hasn't changed the wheel and kept the existing cover.

Also, single blades are typical of a 14B turbo.

Hope this helps.

 

[N2O_ZX2]

Ill have to take some good pics of the new toy and post it up here for you guys. Its pretty sweet and I was really impressed. He had it listed originally for $1,000 but I asked him what the lowest he would go would be and he said he'd take $800. The body is in perfect shape and everything. Its white with a black top, and it has the silver rims instead of the white rims. I hope that replacing the auto tensioner will fix its timing jumping though, other wise it might need a new head.

Actually the evo spools a tad quicker. The wheel is lighter. IMO it the best street turbo out there for the price. I went from the s16g to the evo 16g and there was a remarkable difference at the same amount of boost. I myself wont ever own anything but the evo3 turbo. I wont even take a 20g over the evo, but thats just me. Thats how pleased i am with it. Out of all the 16g's, the evo is the best hands down. Amazing turbo IMO.

Right, but you really think a newbie is going to know this???? He may know it now for future but half the time you can barely read them. And you dont know if the housings have been changed or not. This way you know for sure.

True, but you have to look at the pattern of the blades. The turbo that is in question would most likely be the E16G due to the compressor blades.

I stopped by the vfaq page on turbo comparison and found this:

"How to tell a 14B from a 16G: both the 14B and 16G have TD05H cast into the compressor housing. So how do you tell them apart? Pull the MAF hose off of the turbo, and look at the blades of the compressor wheel. The 14B has all of the blades at the same level, while the 16G alternates high/low - the 14B wheel is on the left, the 16G on the right:

"16Gs normally have a 7cm turbine housing, while 14Bs have a 6cm housing. Now since there are so many custom turbos out there, you can't just assume you have a 16G if the turbine housing is a 7cm, as there are custom 6cm 16Gs out there. However, you can at least tell the various turbine housings apart - 6cm housings have 060 cast in them, 7cm have 070, and 8cm have 080 cast in them. The 8cm housing is not a normal stock housing, but Forced Performance and other DSM vendors have started ordering them from Japan, so you can now bolt one on a 14B/16G/20G hybrid for higher topend flow without clipping the turbine wheel."

Correct me if I'm wrong.

Without taking the comp cover off to inspect the wheel dimensions, you can also tell the differences between the 16g's & 14b's as the blades are all the same height on the 14b while they are staggered on the 16g series.

Hmm. I don't know about that... Yes the evo3 16g wheel has thinner blades but they are significanly deaper and broader. A true evo 3 16g also has a tdo5h turbine wheel made of inconel, a steel alloy. But that makes it stronger not lighter... from my research.

My small 16g with stock cams and an average tune infront of 2 1/4" exhaust spooled to 20 psi by 2500 rpms !!! It was sooooo fun. but up top was not so fantastic. Not bad but not like an Evo3 or my 18G or my 60-1 . The lag is worth it to me. I'll wait a split second to get way more power. Or just downshift .

Almost right ... It is mostlikely a 16g because of the blade orientation. The seial numbers on the compressor cover suggests that it is an EVO3. So, in all likelyhood, it is an evo3 16g. ... But only by removing the compressor cover and measuring the wheel will tell you for sure... I have an 18g with a 14b compressor cover (w/ the 14B serial number) from Forced Performance He!!a stealth .

BTW, the 18g has the same blade orientation as a 16G so does the 20G. But the 18g wheel does not look much larger than an evo3 wheel unless you have them side-by-side for comparison. If you can get a mic in there you can measure:

TD05H-16G "small" .......inducer: 1.830" exducer: 2.365"

TD05H-16G "large" .......inducer: 1.892" exducer: 2.680"

TD05H-16G "Evo3" .......inducer: 1.902" exducer: 2.680"

TD05H-18G ..................inducer: 1.992" exducer: 2.680"

TD05H-20G ..................inducer: 2.070" exducer: 2.680"

All the above turbos have the staggered blade orientation.

I was running 18lbs with my s16g reaching boost at 2500. I now run 24lbs on my evo3 and hit full boost at 2700. If its not any quicker its atleast the same. I did have 3" exhaust but i also ended up with lag so i went back to 2.5" which is perfect. Barely any lag while still having great topend. Never sacrificed anything across the powerband.

P.S. I hope your still not running that 2.25" exhaust with the those turbos

 

[1993eclipseGS]

His answer was found in the first post, I think he knows what kind of turbo it is by now.

 

[N2O_ZX2]

Even though i got my answer i still like hearing what all the little variances are between the turbos.

Ha! with the 18g yes. but i had no cat and flowthrough muffler. I don't know, didn't really need it as i was getting what i wanted out of it... With my 60-1...I'm building my exhaust now.

 

[kronus]

dsm-onster: Thank you for the correction. I didn't realize that the E16g also had the staggered blade orientation.
