IHI RHB5
 

what are the specs on a IHI RHB5 from a 88 Ford Thunderbird Turbocoupe. t3 https://i16.ebayimg.com/04/i/04/61/ag/a8_1_b.JPG would that mount to my turbo on my site

Re: IHI RHB5
 

think it .60/.63

Re: IHI RHB5
 

whould that work on my turbo

Re: IHI RHB5
 

so

Re: IHI RHB5
 

the ihi on t-birds is tiny as ---- but ive heard of people making hybrids with other rhb5s, which still produces a tiny turbo

Re: IHI RHB5
 

is it a 0.48

Re: IHI RHB5
 

It might get you to 200 whp.

Chris Gerhardt ran two of them on a 302, he said it strangled the top end but still had good power. To do over he'd have gone with the T3's.

FYI, the 87-88 Thunderchicken's IHI has the VJ22 compressor which is the biggest OEM unit I know of. You may be able to take aftermarket or WRX or STi swill and make a hybrid, but you've just entered a world where things aren't so cheap and the turbine is still way to small and restrictive.

Single turbo on a 302, grab a Holset HX35 or HX40. Good for 550 and 700 whp respectively. The stock turbine on the HX35 might be a tad small for you and hinder top end, but for the price they go for used if you run out and buy a new 16-18 cm^2 turbine housing it'll probably be the same price total for a pair of used .60/.48 or .60/.63 T3's.

I say bolt the big ---- turbos on there, split that wimpy 302 block down the middle, then stick a 351W in it's place and prepare to die because you can't hold the car to the road. It's how I plan to die! O0

Re: IHI RHB5
 

but is it a 0.48 houseing

Re: IHI RHB5
 

No, don't get T3 mixed up. The T3 on the Warner Ishi/IHI is a very small T3. The only thing T3 about it is the actual inlet from the manifold. The turbine itself is still the turbine used in the IHI RHB5 VJ11. It is a good ENTRY LEVEL turbo, but shouldn't be compared to any of the larger T3's.

The turbine trim would be a .67 because 42.4/51.8^2=67

And the compressor trim would be .55 because 39/52.5^2= 55

I haven't calculated the A/R of the exhuast side but the VJ exhaust side has ar A/R of .46

EDIT: I should clarify that the Warner Ishi/IHI VC32 (T Bird) and the IHI RHB5 VJ11 share the same turbine. All numbers are of inducer/exducer and are in mm.

Re: IHI RHB5
 

Stevemode said it best - "...Yea, I run that T-Bird pump, that .48/.60..." That's my $.02. I have no i-d-e-a besides what the song says. LOL. I learned how to turbo from a song.

Re: IHI RHB5
 

AS SAID, don't get your T3's mixed up, I know what I'm talking about. There are 3 different turbos that come on the turbocoupes 1) an aiResearch .60/.63 T3 2) a Garrett .60/.48 T3 3) the Warner Ishi/IHI small T3 HOUSING...the turbine is NOT a Garrett T3 turbine. Which is the one you're showing in the picture.

Re: IHI RHB5
 

why didnt you at least mention the numbers on the turbo.

To the IHI guru. Why are some turbos labeled VJ and others VI.

Re: IHI RHB5
 

the only thing that the IHI thunderchicken turbos share with garrett/airesearch T3's is the flange. Other than that the IHIs are alot cheaper/smaller. Depends on your tastes i guess. I say go much bigger

Re: IHI RHB5
 

I some how got 212whp and 262wtq from a Probe/T-Bird IHI hybrid. Having 2 would'nt be so bad, 424whp 524tq :P

Re: IHI RHB5
 

VI series are typically Isuzu and VF are commonly found on Subaru. This shouldn't be considered gosepl though as there are many different IHI's found on many types of cars, the most common is what I am referring to.

Example:
The VI-34 (Isuzu Impulse turbo) number is called a short spec. V=Vehicle I=Isuzu 34=the first 2 numbers in the long spec. The long spec is actually the part number on the IHI bill of materials or the list of parts that make up the turbo right down to the snap rings, nuts and bolts. RHB5 is typically called the frame size. RH=Right Hand(the direction the wheel rotates) B=Generation( IHI is now on F in 2005) 5=size range(5 is approximately 80hp to 250hp) Within a frame size things like shaft diameter and bearings are common.

I wish i would of saw this on tuesday. I found the exact same one @ a junk yard and thought it was a .48/.60...well $100 later and in need of a rebuild, I'm pissed.

Re: IHI RHB5
 

Lee's 91 Impulse RS - probably entirely different from the earlier RWD Impulse I think you mean - had a VJ11 on it.

The turbo was identical in every way to the old skool Subaru 1.8 DL turbos, except the turbine housing had a very strange flange w/ 5 bolts. Three were the exact same pattern as the Scooby stuff from late 70's-present, the other two were added in for no good reason I can think of.

Just a verbal footnote - seems we've gotten onto IHI's in general, and not the 87-88 TC's unit any longer.
