Not sure on that one- any idea what the compressor specs are?

Forced Performance Turbochargers: Syclone/Typhoon 17c Turbo

Although thats a good question for Justin..What determines the staggard comp wheel on mits turbo's? Just the way that turned out or?

Click to expand...

Not sure what you're asking here. Staggered-blade wheels are designed for better efficiency in the higher boost levels. Compare the maps between the Big 16G and 17C, two turbos with nearly identical specs:





Notice that the efficiency islands extend to much higher pressure ratios on the 16G versus the 17C. At 3.2 PR the 16G is still within a 65% efficiency island while the 17C is.....surging.

So lower levels were still talking about moving the same amount of air, vs higher one is gonna be waay out of range..But F it..It happened..So, next time you want to try something new,DON"T.

Which is like Why the hell would someone do this..And that sir is a good question..But Unless there has been side to side comparison before.,not just taking specs, but use on a 4g with tdo5 turbine..

So in reality, the only thing different is gonna be comp range.I still want to see.


As it sits tho..Great upgrade for the 13g, and t25..But we have those, it's called the 14b,16g, and t28. Madmen,I tell you.

If you don't try something new then you never know what will work and what doesn't. In this case, however, we have evidence that this compressor swap HAS been done many years ago....if it was worth doing wouldn't you think it would still be super-popular?

I'm still interested in it. If it dont work,well???Back to the 14b? And at least staying in a td05 trim, a comp wheel change will be a cake walk.

Edit..I'm no expert but if you look at the 17 vs the big..If the 17 stays around 70% yes there is less pressure ratio, but 4% higher efficiancy.So even going to 66% on both..Ohh I see whats goin on there..Exhaust gasses go into the turbine, witchcraft happens,and you go faster..

I'm sure you should have those maps color coded by now..

The first edit was dick version..You should see the final versrion but keep those links on this page.

I know 3 sites just got some actual hits..

The first two really have just hearsay.

the third,only this "I had that turbo on my previous setup. My best time was a 12.59@108mph with 21psi and pump gas...it seems to be like a Big16G, but it doesn't seem to have the top end of one, unless you run it over 20psi."

And then more hearsay,, the 19 should flow more that big..

I don't wanna run a best of 12.59,I know that for sure..You got your pen ready..14b vs 19= 19..but big vs 19= big+19,and big = big..But add 14b+ 19, you still getting either a big ass 14b, or small big 16g.

But wait theres more..Past 04 you just couldnt find anything or,not gonna spend hours trying to find one from yesterday that doesnt exist?

I'm messed up in the freakin head.

are we looking at same maps? cause you aren't proving your point. just the opposite. the 17c map is better in virtually every respect. Wider map means less surge. 17 wins there. wider islands means more efficient. 17 wins again (compare at 70%)(17 map is truncated but looks to be far better at 65 as well)
and looks like 17 outflows it as well. and WOW the 17 has 76% window. wheres that on that efficient 16??

and again I have used both the 17c and 19c wheels and they were kickazz good turbos. so don't believe all that crap from those links you posted. there is no useful info in there whatsoever.

try to imagine what the 17 map would like like with a 60% line added. it stops at 65%. and the top of map is very truncated. only drawn to 2.75pr or so.

^ WOW I wasnt expecting that..

There clearly not the same comp map..But im no expert, this is why we have a questions for Justin thread.

turns out turbo was a sweet deal. basically a genuine mitsu FP red size turbo. compressor wheel is 55/75mm and turbine wheel is standard 6H 58.7/67mm.

IHI RH6B from some type of small-displacement Japanese diesel engine, like a Yanmar or Isuzu. Not really a good choice for a high-boost application, although this may potentially make a Honda guy's day if he's running below 10psi.

The parts kit should you choose to service it is either NN199833 or NN199835...I can't really make out that "VC" number on your cover to get the correct kit. There's a number missing....it should say "VC" with six numbers after it, but I'm only seeing five. Regardless, finding an IHI dealer to buy parts from wouldn't be an easy task.

IHI turbos are used on soobies. Or at least I know you can buy them for a Subaru. But the flange is diff from a soobie. So probably an isuzu 6GB1T er something. Yanmar's generally use MHI turbos don't they?

this is a TDO5H but the serial number reads 49178-0 0, so is this a knock off TDO5H or what, i cant find that number anywhere? Thank you for the help.

Judging by the way the number is stamped with the circle, you have a Small 16G (49178-05200).

ok thank you, im thinking it definetly needs a rebuild because its burning oil pretty bad. Im looking at getting the evo III turbo, with this one already on there i technically wouldnt need the 2g install kit right? the evo III should bolt right up?

Fitment would be identical- although if your turbo doesn't have wheel damage, it can be rebuilt for much less than acquiring another turbo....and still be just as reliable as if it were new.

yeah im still deciding whether i want the evo turbo or rebuild the one i have, i guess it all depends on my recent funds. thank you for the info

I know this has been covered but my issue is a bit different. I know for sure its not a 14b as the fins are staggered from large to small. My problem is what type of 16g do I have. My serial number 49178-01xx0. The 2 numbers that tell me what type of 16g are not there. I thought they were filed off but there is no marks from filing. also there are no numbers above the serial number like I see on most 16g's. I've read the mounting flange on the legit evo III 16g's curves in and around the bolts as opposed to being completely square. Mine curves in. Any other way to find out what I have?

Hi, im new to 16g turbo, So i search and found nothing about this big 16g I wanna buy on craiglist. this 16g looks real, I mean everything except the turbo serial for it is 48179-01420 instead of 49179-01420? Any idea guys? is real MHI? Thanks in advance.

Yes that would be the mhi big 16g. I say get it.

IDK how post photo, but I triple check and the number and it is 48178-01420.

If you have the pic on your PC harddrive......

get an acct at photobucket/flicker, ect ect- someplace that can host pics that you can upload


when the pic is uploaded online, right click the pic and copy the url

when you make a post, in the reply box, you will see an icon that shows two mountains and a sun in what looks like a box- or a pic for intuition purposes

click betweenfor some forums- otherwise- paste the url in the provided field, submit post- viola- pic to post magical voodoo witchdoctorey at your fingertips.


otherwise if you program at all, you can type the " by and if you like

I think that is a "Big" 16G

420 is a Big 16g.

Any idea what this ~60mm (Garrett?) knock-off is supposed to be? The blue tag says "turbocharger" and some illegible scratched off, probably bogus, serial #
