GT2860RS on a stock B18B motor?
Just curious if it is possible to make 320whp with this turbo on an untouched B18B with 93 octane?

Re: GT2860RS on a stock B18B motor?
It shouldn't be possible, unless you're pushing the turbo much harder than you should as well as other factors that wouldn't yield a good build/tune. The system would be way out of it's efficiency range.
Don't forget the non-VTEC heads flow much less CFM than VTEC heads. This will greatly effect how the turbo responds and makes power. GT2871 would be a better option from the GT family. |

Re: GT2860RS on a stock B18B motor?
the gen2 gtx2860r would be able to do it perfectly fine.
GT2871 is overkill. The log manifold is going to hold you back a LOT. You'll probably hit knock limit of 93 pump gas before you reach 320hp, especially if you use the log manifold. |

Nope. You remember, we dicussed this before early 2018.
I've come to realize if I do turbo it I will never build the motor so 320whp is probably going to be the limit. |

Unless you run boost by rpm to save the rods and a decent manifold imo the engine wont last long.

GT2860RS is at least as efficient. And remember I was on a cast log manifold also. Took about 21lbs and it was definitely at the upper limit but I daily drove that car and it was run good for 2-3 years. Motor went back to stock, came out and sold to a friend https://cimg2.ibsrv.net/gimg/honda-t...c556e7b375.jpg https://cimg0.ibsrv.net/gimg/honda-t...abe801e384.jpg |

You still havent finished this car yet? lol I feel like you've been asking questions about turbos for 5 years.
Got 3 kids, got several promotions at work and now need a "business man" car, and a mid 30's guy in an older Honda is...eh... But I still love it. The more I look the more I like the Audi A3 8V. Those things seem to have a lot of modding potential. I'd be happy with a 11 second daily driver. |

Man, part of me thinks it will never get done. For numerous reasons...

So how did I do 300whp on a GT2560r?

On 93 Octane? ..
I do think 320whp would be pushing it. Number seems arbitrary though. It was still super fun and surprised alot of people. |

It's always been interesting when the two of you don't agree on something. LOL
