it wont be fine for long. the cylinder pressures are outrageous, and i dont know if youve ever seen one of the connecting rods out of that motor, but they are laughable. 100 shot will lead to bad things, even without detonation. Maybe, just maybe, in a DOHC, like ls or b20b, with the right fuel setup, it could be done. but not on those pencil rods.

 

yes i understand the cylinder pressures are extremely high but thats where the shorter stroke comes into play as opposed to a vTEC 1.6 and U also have to remember that d15s redline alot sooner then most other honda motors so there is less chance of keeping the stress on the crank and rods for a prolonged period of time. i've talked to alot of experts(not to undermind your knowledge)and they've assured me that d15's take nitrous alot better then any other honda motor. even if they have pencil rods.

 

you think that might be because they want you to buy thier stuff?

most people know engines aren't tuned for max performance from the factory but throwing 100hp at an engine that doesnt even make a 100 on it's own is not a good idea.

 

ahh comon, NTX, give it some credit. it makes 102 stock.

 

Actually NTX they experts i spoke with were not trying to sell me anything. [&:]

 

While it is true that D series engines can handle more nitrous than most, a 100 shot is still too much. The rule of thumb with nitrous on stock internals is no more than 65% of your stock hp for a daily driver. Have fun rebuilding your engine 3 times a year.

 

maybe he's into that kinda thing, you know... practicing and all.

 

I have nos so i'm not against it by any means, but for an "expert" to say a 100 shot is okay (on a stock 100hp d15) leads me to believe they don't know as much as they think.

 

yeah, i am a little nervous about people like that selling nitrous accessories.

 

I don't see any problem here. I ran a 100 shot of nitrous before going turbo. I took it just fine. For about 6 months. Cylinder #1-150psi, #2-30psi, #3-145psi, #4-80psi. Rods were fine, it's the rings that went on my engine (75K miles , oil changed every 3K).

But hey I only ran it once or twice a week and once at the track.

Yes I am vtec, but trust me I am an expert on the fact that it CAN'T take it.
