The power will flat spot instead of continuing to increase. If it makes 200 whp from 3500 to 7000 it will feel slower to the butt dyno than something that makes 200 whp near redline as a larger turbo would... And it would be substantially faster than the peaky setup due to a broader powerband. Its not a cut and dry matter.

There's no snap rings on that turbo
I had one just like it and Everything is bolted on. I broke all four of the bolts and re-drilled them out and threaded the housing with 3/8-16 Tap. A torch and pb blaster just wasn't enough, but yours might not be rusted bad.

good job on pointing out what the noob already said

Re: IHI RHB5 VF28, on b20b, in DA
god damn right i'm hear to learn, i want to build something that's going to work, I've been into honda's for a while, done all my own work, swaps ect, not about to let someone else build a turbo setup for me, just pickup what info i can from guys that know more than me about it and get my hands dirty, I ride in my buddies twin cam ZC'd turbo is what got me going on this
Now, if i'm not impressed with this turbo performance can i upgrade to an STI turbo later on, i believe it's a VF34? from what i gather IHI's all have a gay "tri-flange" setup I plan on modifying a b-series T3 mani to work with this flange style, and i would probably have to modify the down pipe flange, and inlet for the intake, is the VF34 alot bigger than the VF28? Thanks for all USEFULL information, and feed back, I appreciate it

yes the vf34 is a sexy turbo. its bigger and better in every aspect of the word. you might want to run a external waste gate when you do decide to run it though the stock is set pretty high for a b20

I also have a low compression b20b. You should just sell the manifold and turbo setup to someone with a sohc. Buy yourself a cheap turbo off ebay run an oil restrictor and boost 10 psi. My set up is as follows,
Internally stock B20B
Victor X manifold
Tubular turbo manifold
Ebay Turbo t3/t04e .57 trim 50ar cold/63 ar hot
ebay charge pipes
greddy type r bov
tial wastegate
sds extra injector controller
USDM ys1 trans
chipped ecu rev limit 8200
car has run 12.3 @ 115mph
Been boosted for about 10 months now.

Re: IHI RHB5 VF28, on b20b, in DA
those are pretty impressive numbers, i'm weary of ebay turbos though as i am going to be driving the car alot and counting on it's reliability, i think i will sell the IHI setup but am more leaning toward a DSM 14B ,
also i found a pretty good deal on RC 310cc injectors would these be sufficient for a turbo setup like mine or should i go for the DSMs instead, they are cheaper...
i since have swapped ls cams in the b20 and ran a couple 15.2s which i think is pretty good in a heavy DA the cams picked the midrange up pretty good but any way, 14B, RC 310cc's?, and who wants a VF28? haha
