IHI Turbo Sizes.... HELP!

[Maeda]

Ok i got an IHI turbo.... I'm pretty sure it wont fit... but i got it cheap ^_^ and its supposedly the equivilent of the T3/T04E...

does anyone know what size the housing is!? I'm really having trouble finding an exhaust manifold to fit this thing~!!!

If there isn't one where could i get one made? and how much?

Where would i find inlet and outlet pipes for the turbo? o.O

HELP DESPERATELY NEEDED

OK i found out it will fit a T3 manifold... anyone know anything else id need thats anything special due to the fact that it's an IHI?

[andrave]

my brother had an IHI turbo on his thunderbird and its crap. I dunno if the new ones are any better. His is a T3 substitute but its pretty slow to spool up for a stock turbo and its ultimate capabilites are pretty low.

[litlespic]

IHI's, are smaller than a t3 .48, sorry.. they do come on the 87-88 turbocoupe's, and a t3 is the most popular upgrade for them, it is a quick at spooling, and makes 18psi before the efficency drops, and the TC's came with 245hp.. its not a slouch, just a regular t3 is better.. there is a smaller IHI that came on the chevy sprint, which had a 3 cylinder suzuki engine... I have seen one guy put the TC IHI on a spring and said the difference was night and day.. but goin from a turbo you could fit your hand around to a turbo just smaller than a t3 is probably a big gain.. these are the only two IHI's I have seen and heard of.. maybe there are more.. but I am unaware of them... Ill go look for some pics and see if it is identicle to yours...


-THe only thing I can tell you is it is a RHB5
and that the Thunderbird had I believe the largest compressor of all the RHB5 lineup.

RHB5s also cam on Deloreans, Ferrari GTOs, Fiat Spyders, Subaru WRXs, RX7s, Probe GTs, and Escort GT turbos among others...-

Here is a site I got for the IHI turbo's - http://www.ihi-turbo.com/turbo_RHE-RHF.htm

[andrave]

yeah in the thunderbird community they replace ihi's with T3's asap. The thunderbird is a 2.3 liter, by the way.
My brother's IHI will hold 15 psi with his boost controller but he says they don't go much higher.

[Maeda]

i think its a VF22+ or something? 6 Blade on one side 11 blade on the other... ill post a pic later if somebody thinks they can identify it....

And its "foot print" (i think thats the right term) is that of the T3 because it bolts onto a T3 Manifold soo i'm guessing that its a copletely different IHI then the ones you thinking of...

The guy that sold it said its the equivalent of the T04E Compressor and its capable of 20psi max(?) I'm still waiting to see if he can give me exact numbers though... =\ it's also supposed to be run with a 35mm wastegate, i dont know if that helps but i thought that wastegate size was relative to turbo size...

The price was right even if it is a tiny bugger ^_^ but i really hope it aint tiny =)

Oh and im only going to run 10 psi or 250 RWHP... whichever comes first

please help me solve this mystery =O thanks in advanced

[litlespic]

can you rephrase that foot print part??? the ihi and t3's have the same 4 bolt flange to the exhuast manifold... the elbow's are different..

you might only want 10psi, and 250hp, but this turbo, that is THE LIMIT... almost any mods made to a stock turbocoupe with outa better turbo adds maybe half a hp before 4500.. when the IHI doesnt flow enough air to make the hp's.. it does spool quick, but a t3 is just as easy to find, actually a helluva lot easier to find, and would do so much better than this IHI

[turbo240sx]

on my probe i have the 2.2 mazda turbo engine with the IHI RHB5
i have no complaints about IHI. this little thing pushes alot of boost ive been running mine at 15 psi plus for over a year now and have a buddy who has 180,000k on his at 15 psi. no smoke or loose shaft. my opinion they are good quality turbo's

[Maeda]

need i mention again this is most likely NOT an RHB5 but is actually bigger...

The guy i bought it from had it on a 2.2L prelude and it spooled at 3000 rpm tuned to 12psi boost? so im almost positive those characteristics dont fit a smaller then T3 turbo... dont you? =\

im still sticking to my theory that its a VF series IHI, unless somebody can post some information proving against it...

I can bolt it to any T3 manifold with no problem... is my rephrase simple enough?

[litlespic]

Yes, that is what I thought you meant but wasnt sure...

It can spool at 3k all it wants, and boost to 12psi, but if its not bigger than a rb, it wont FLOW enough air.. you might be right, there might be a bigger IHI but as far as anyone on turboford knows the rb is the biggest IHI made.. Im not trying to say that your wrong.. just htat out of 4000 members on my board, none of them have seen a bigger IHI than the rb.. but go for it.. all I can tell, whatever floats your boat

[turbo240sx]

im only trying to help you out, you dont have to listen to me, but my
RHB5 IHI spools at 3000 and to 12 psi, and it came on a 2.2, this sounds like one. look on the comp housing there are no numbers on it. the 2 most common IHI ive seen is the RHB5 off the mazda 2.2 and a IHI off a 87-88 t-bird 2.3, that had a slightly bigger wheel and housing than the RHB5. but still had the same center section and exhaust housing as the RHB5.

[andrave]

I have seen guys with stock eclipses boost the turbos up to awful high levels... its not whether or not a turbo can run that much boost, its the efficiency at that boost levels. Just like an engine might be able to run at 9000 rpm, it doesn't mean its good for it. Turbos are susceptible to heat damage and running them at a higher boost level than they are relatively efficient at will:
1.) over heat the intake charge (remember the whole point of intercooling is to lower it, cold air is more dense).
2.) risk damaging the bearings, especially if you have no turbo timer. the oil will coke and the bearings will do.
3.) catasrophic failure. The shaft can snap, the impellers can disintigrate, or stuff can melt.
This issue's month of turbo talks about all that stuff, and I'm still learning myself. I'm not an expert but everyone I've talked to on the 2.3 turbo forums seems to agree with the people here that the ihi isn't good for high boost. Keep in mind that it runs 15 pounds stock on the turbo coupe.

[litlespic]

Totally agree, I didnt meant to say that it could boost forever.. but if the guys dont have 75 bucks to snag a t3 from the junkyard they get a gillis valve and boost to 18.. most see 21-25hp from it... on 2.3's with stock turbos we get about 7hp per psi..

The thing I am mainly trying to get at, is that the boost and CFM are two different things.. you can boost 1cfm to 35psi, but will gain more from 200cfm at 2psi... if its a bottleneck on a stock 2.3 why would it be "good" for a 2.4 DOHC???

[ca18det]

why dont you just look on the compressor housing tag and tell us the model number. it isnt hard. it says model number: xxx
ihi are hands down teh best turbocharger company to date. they have the highest qulaity products.

[Maeda]

ill post it up as soon as i get it... I posted this up to see if anyone could give me some compressor maps because i cant find any =\.... I know ihi doesnt really want to share the info but just wondered if somebody with lots of ihi experience would know

IHI Btw makes a lot of bigger turbo units just fyi.... and they come in lots of different sizes for many applications like anything else....

[ca18det]

no ****. of course they make bigger turbos. and how can we even help you out without knowning the specs on your turbo. i could put up a map of a rx6 on here but i highly dount you have one of those.

[Maeda]

sorry ca18det i wasnt referring to you in my post, but i was referring to litlespic who seems to think the only IHI's around are smaller then T3 sized... =\

Ill be recieving the turbo in the next few days ala the magical UPS fairy so hopefully ill be able to post some serial # or pictures or something... maybe it's something new and un/rarely seen ^_^

[Maeda]

ok got my turbo!

SPEC: GM4

S/N: 108641

P/N: 10154652

can somebody identify this snail cuz i cant seem to find anything -_-

here are some handy pictures (sorry about the webcam resolution its all i got)

[ca18det]

please tell me your joking? your not really putting that in your 240 are you?

[Maeda]

gonna damn try... unless somebody can provide me with a map to tell me not too....

instead of criticizing.. you mind telling me WHY its not such a good idea to use this?

[ca18det]

its a turbocharger from a 6.5l diesel engine. you have no reason to use this turbo. i'm not one to complain about lag(ca18det with a t51r kai from hks) but this thing will have horrible boost reponse. thats even if you can spool it.

[Maeda]

just going on words alone... i have information to believe otherwise

what im really looking for is some #'s or compressor maps and i've looked everywhere and came up with zilch... so im asking here(& whoring my thread..sorry)

heres some #'s since i have the unit on hand to measure...

inlet major diameter - 3 inches
inlet minor diameter - about 2.5 inches
exhaust fan side diamete - about 2.75ish inches

how does this compare with peoples T3's? T04B's? T04E'S?

[ca18det]

dude if you dont believe me fine. just go google ihi gm4 and you'll see. thats how i found out . called turbonetics and ask they will tell you. measurements mean dick. alot of turbos can measure the same and be drastically different.

[DuffMan]

IHI makes a whole range of turbos that range from big to small.

GM4 is actually a stock replacement spec for GM trucks, not a normal off the shelf turbo. Actually that's probably going to be too big for most applications

[Maeda]

for now measuring is the only means i have of finding anything concrete cuz for all we know.... we know nothing cuz we can't find an ihi compressor map... anyway i put an inquery in at IHI... and im going to revhard this friday to check if this thing will bolt up

and until then i guess this'll just be a giant experiment =\

DeLorean was powered by a naturally aspriated V6 of Peugeot/GM descent and it churned out a whopping 130hp.

There were NO turbos.
