I been told I can make 200 bhp on my d16 engine with the RHB4 IHI VJ11 turbo from a mazda 626.

With my limited knowledge and alot of searchin, I'd say thats not true.

what you pro's think?

its possible but i dont think i would want to try it. being such a small turbo it would probably run out of its efficency range by 200hp and choke your engine out on the top end. i have got a ihi rhb5 from a ford probe that i am going to be using on my d15b7. being a non v tec engine and only producing about 100hp n/a i think it will be suitable for 180hp hopefully on a good tune, or atleast thats what i am shooting for. hope this helps!

thanks very much boss. this hmt i'm being offered is pretty cheap. My d16 is 130 bhp n/a - you think is a realistic bhp with this turbo?

i would honestly say step up your turbo one or two more sizes if you want your turbo to operate efficently and make 200hp. or if you really really want to use that turbo, you can look up the specs and see where it would make the most power on your engine. i dont know the specs and all on your turbo, but you say its a rhb4. so it cant be that much different than mine. i am going to tune my car around the flow of the turbo. if that make any sence to you. but yeah i expect my car to be like a factory boosted civic. nothing crazy, just a little more torque than i have got now. my car is a torque turd. :-(

thats some good advise. cheers ronmat85.

if its a VJ11 I'm almost sure its an RHB5. I'm using a VJ11 right now, its allright but nothing for peak power

what engine are you using it on? more details please!

those are good low boost setups. more of a beginner turbo.
