Hello my Honda Bros
So I'm doing a RHD CTR replica build with all out interiors and exterior. Including b16b CTR MOTOR & tranny.
I also plan to boost it and bought RHD carbon fiber boost cage pillar.
Then some came to me and crush my dream.
Guy told me you can't boost b16b type R due to high compression. And cams overlapping
And why we mostly see b16 si and b18 ls gsr boosted due to lower compression.

Is it true?
If so then what can I do so I can boost on my CTR motor?
Can I use my stock internal or do I have to get forge piston?

Btw, I plan to put around 7-8 psi. I don't car if it's only 230 hp or less.
It's only gonna be use for weekend and meets

Buy a quality turbo kit (or piece together a quality custom turbo kit), a new set of fuel injectors and engine management. Speak to your local tuner on which brand he prefers... and then tune it safely. The higher compression of the B16B reduces how much boost you can run safely on pump gas, however, the higher compression engine will make more power at any given boost pressure than one with lower compression. This means you will make more power at lower boost... and thus, meeting lower target HP numbers will require lower amounts of boost compared to what your friend is telling you.

What he is suggesting was the normal way of thinking about ten years ago... but tuning has come a long way since then and technology has improved. The current direction combines higher compression, more aggressive cams and lower boost pressures. This creates a more responsive engine with lower emissions at street type power levels... and massive power gains at maximum boost levels on fully built race engines.

So pretty much you're saying on stock internal, just get quality boost kit, professional tuner, and have psi around 5-8 psi?
Will I able to use regular feul or do I need E85? I live in city and station only Carry 85, 87, 91 octane

Better use octane booster 91 octane is border line

Who are you planning on having tuning? What management system? I don't see 91 pump gas being a problem as long as your tune is on point. It has been proven all b series can be safely boosted to 300 - 350whp. I have a almost complete setup perfect for you if interested for cheap. I just upgraded and building motor for over 400whp.

I boosted my b18c type r with 8lbs, bone stock motor, tuned with s100 hondata. dynoed 274whp back in july. daily driver, NO issues. Knock on wood. And when I got it tuned, it was tuned for using 93 octane fuel.

Schister66

With a good turbo setup and a competent tuner, you should have no problem making 300-350whp safely on that engine. Stop thinking in terms of PSI, it means nothing.

Set your goals in terms of whp and develop your setup around it.

Stock b16b turbo 9 psi with water injection tuned on hondata s300

@speedjunkie_g35 if you still have your other set you were offering to him I'll take it off your hands
