Heres my setup. I have heard that CTR pistons cannot handle nitrous? Anyone know about this being true? As some of you who recently read my other post. I am looking to hit around 230 or more in my ITR. I guess what I am wondering is if I am hitting about 205-210 now (needs to be dyno tuned again) would it be worth it spending the 2k or more to hit 230 wheel or just spend the 900 and get a 50 shot?

Portflow P&P head,
ti retainers,
Toda Spec B cams,
Toda cam gears,
Toda valve springs,
CTR .25 pistons,
rc 310 injectors,
aem fuel rail,
fidanza aluminum flywheel,
act hdss clutch,
jdm 4.75 fd,
dc jdm 4-1 header,
carsound 2.5" cat,
SMSP custom 2.5" ss cat back exhaust,
injen short ram intake,
hondata standalone management.

 

you have to ask yourself, do you feel lucky?

well, do you?

not something i would do.

 

i'd do it...since you were gonna spend 2g's anyways, if it blows up, you can put that 2g's into the rebuild and hit your goal...hahaha.

 

Well its not about feeling lucky or not. A direct port system properly tuned I feel should be ok with just a 50 shot. Does anyone have any helpful information?

 

well, the only thing you can do is do the math. calculate your REAL compression ratio and go from there. but it still comes down to if you think its safe or not...

and it sounds like you alredy have your mind made up.

 

compression ratio when i first got it was around 12:1. I know nitrous loves higher compression, but it can also be dangerous.

I will do the test again when I get it dyno'd.

But I feel that a direct port instead of the typical intake spray, will be much safer. I figure each cylinder getting a = amount of spray and keeping it just at a 50 shot would be safe. Especially cause I don;t plan on using it much more than track.

At first a tuner told me I could handle a 75 shot, so I figure 50 isn't too much stress on the engine and much safer.

My primary concern in CTR pistons I have, can they handle no2? I have gotten mixed responses in other threads about this.

im a little confused by what you mean, so if my answer doesnt make sense thats why, haha.

i assume you are talking about the tops of the pistons, and the coating on the top. if that is what you are referring to then i have never heard of them having a bad reaction with nitrous....

hahaha honeslty, I am not 100% sure what I am talking about... Someone once told me on here that CTR pistons are iron and would melt or somethign with nitrous.... yea i dunno, that help any? lol

 

Honestly, If i was you I wouldnt play with nitrous man. It can get expensive if not done right. I use to be all about nitrous, dont get me wrong its fun and easy power but 1 lil mess up can ruin ur whole motor. I blew a 00 GSR motor with a NOS plate system on it on the dyno. And all because the tuner put a lil too much timing into the motor.

 

not only that but the ABUSE it puts on a motor isnt good at all.

IRON!!! HAHAHA.

nah man, as far as i know they will react to nitrous the same any honda oem piston will.

haha o ok. Well then.

 

Direct port rarely if ever come in shots below 20...

i.e. 80 shot DP will require 4/20hp jet setups.

A 50 shot would require approx. 4/12.5hp jet setups...Are those even made?

I have never seen anything below a 20hp shot before.

what are u talking about? a 50 shot is good for almost that much wheel power..... depending on wet or dry. and I do believe i saw a NOS system direct port 50 shot for sale in classifieds recently.
