Scathcart/// I'm sorry. I did say Rising Fuel Pressure Regulator. My wrong. Anyway, I agree with the Tranny conversion. I will nonetheless pusue the Nitrous set up with a back up Tranny at hand. Just In case...I can actually get the Drivetrain right now but minus the Tranny.

A side from that, I'll keep you posted with my upcoming set up.

Thanks for the good words. I try to write them so anyone can understand them, and keep all the "little things" out in the open.

Nice choice on HP range. What are your plans thus so far?

np.
You may be able to get away with the N/A drivetrain, but I think the "hit" of torque during a shift would kill it pretty quick.
You know my addy and PM.

The method of just tapping the button in TFATF would only allow the nitrous to come on for those few milliseconds while the button was tapped. As well… the “too soon Junior” line makes no sense. As they are claiming them to be 10 second cars, hitting nitrous for 10 seconds at a time is fine, and thus, the person hitting the shot sooner would be in a better position.
LMAO I never did get that

unless of course. they are really running over 20 secs

Good write up, thanks. If a 87 N/A with 110 K ( it has another engine in it with unknown miles ) with a new fuel pump be able to handle a 50 shot ? I was thinking of either NOS or Zex, any suggestions ?

milage doesn't really matter. Your enge won't break b/c you add horsepower and it already has kilometers. The nitrous will add 50 hp worth of wear to the engine, during use, so it won't make that much of a difference to your engine's longevity.

So, what brand do u reccomend ? I don't really want to do any other mods beside the kit itself, and you even mentioned that n/a's don't have the right fuel pressure regulator, so would a 50 shot ( wet or dry doesn't matter ) be able to be pulled off without any other essential mods ( nitrous gauge and heater are obvious )

I recommend NOS. Lots of history, I use it myslef with great results, and they offer tons of accessories.

Go wet on a stock motor, since you don't know the condition of the injectors.

Its risky running the stock fuel pump... but go for it.

Thanks, that cleared up a lot of things for me. Great read!

Would you (Scathcart) or anyone else think this to be an appropriate lesson of Nitrous for any non-rotary car? How close are the two comparably in how they work? I understand most of the set up will be the same, but are the shot #'s going to differ greatly(or any other stats)?

I was really wondering how much of it I could recommend Honda/DSM/Nissan drivers read for their safety and for reference of Nitrous systems. It was so well written and explained I would like to know if this knowledge could be passed to some others. P.S.- I do know some legitimate Honda people w/good engines, no rice, and a thirst for nitrous.

Scathcart/// Based on my applicable mods, In relation to Nitrous, found In whats to be a real long thread, I mentioned my mods. I have the S-AFC on the way, will be removing my s.s Hi-Flow Cat and will be Installing my long awaited Walbro FP (255) followed by a dyno session to tune all of the above with my existing mods.

Will the above provide a good basis or even a solid foundation prior to adding Nitrous to my car?

I will also look Into a FPR but I can do without It right now considering I will have the S-AFC to tone the fuel down right? It's not until the addition of Nitrous I should look Into a FPR to be Incorporated with my existing fuel mods, right?

Finally, I will be porting my Manifolds soon. Do you think I should dyno It with the S-AFC just to be sure I am getting an accurate measure of air to fuel ratio? Or It doesn't matter I could do after?

Piston engines differ. They'd be better off emailing me, as even different manufacturers make requirements for differewnt mods. However, the same basic principles apply, only the required mods per hp range would differ.

Definitely dyno it with the S-AFC. It'll be the best bet for power without nitrous, and the safest for with it.

You have a great set-up for nitrous use. You could easily spray upwards of 100 hp shots, once you get a drivetrain that can handle it.

So, just the fuel pump eh ? What about this pump, will it be sufficient ?
