IHI RHB5 on a b-series?
Ive got a brand new from the factory IHI RHB5 turbocharger from a 89 Mx6,I was wondering what good it would do to get a log style trubo manifold made so i would be able to use this turbo or if there would be any downside to it?im only gonna boost 8lbs on a basically stock motor w/60k on it in my Ef hatch,any info would be greatly appriciated thanks for your help.

Is that depending on the amount of boost or on the flow capability?
I got a kkk k14 turbo the other day for my project and it's about the same size as a RHB5..if it runs out of oomph that early it might not be worth the effort trying it.

I can tell you myself, I have that turbo on my b16. It's REALLY small...killer fast spool, but it falls off very quick. The power stops at like 6k or so. Really crappy for the HWY espessially if some DSM is messing with ya...

It only flows 190cfm which is pretty bad. The funny thing, is that Mazda ran them on a 2.2 l (I have one 89MX6 GT), and it pulls ok, but redline is only at like 6k.
If you want to use it, you can get the compressor housing off a T-bird Turbo coupe, and make a hybrid turbo that will flow a ---- ton more. Check that out. www.mx6.com has more info on modding the turbo, since they all have them.
Just an idea, but ideally, a big T3 or a T3/T4 would suit your engine better...
