are there any that would withstand nitro? ive got jdm .25mm overbored, but theyre oem so theyd fry...

 

je works good for me. cp also. its all about tuning i guess. ive put a 170 shot on some srp pistons and it held up, but i would recomend it.

 

je 12.5:1? they would hold up to nitro?

 

thats what i use in most of my cars. have gone 10.88@127 with them

 

as long as timing and fuel is right then you can spray on any compression. but make sure it is a forged piston.

 

can i get overbored je's to match my current setup? ive got the 81.25 jdm itr's..

 

What's the most important thing you have to watch out for with high compression and nitrous? I'm running 9:1 JE with 150 shot.
I want to run the same shot but higher compression. What do you reccomend?

 

as long as you're supplying enough fuel and your internals are strong enough it should be fine.. 9:1 is more than fine for it, thats even pretty good for turbo. i was lookin in the 12.5 range... i take it id hafta upgrade my fuel pump?

 

It's 9:1 cuz it was originally gonna be a turbo motor, but I went with nitrous instead. I want it to be stronger without the bottle

 

i have 13:1 or 13:5:1 i wanna spray it too... i need some of the info too!!..

ok guys lets not get ahead of ourselfs here if you plan on using nos stay below 11 compression,below 10 if its not tuned properly.
shooting a 50-75 shot on a 12:5 motor is basically the same thing as driving with 14:5-15:5 comp during that time. can be done but def not safe.

 

ARIAS Pistons

 

whoops, sorry, repost, look down stupid *** computer

 

&lt;--shrugs.. ive got all that....JE pistons

if youve got pistons that wont fry, a block strong enough to hold it, rods strong enough that wont blow out, and a fuel pump to supply the juice, what else could go wrong? the problem with having a 10 cr motor is theres not much power being supplied to it without being dependent on nitro. with a 12.5 n20 compatible motor, youve got straight up power, and the extra oomph when you want it.

 

ive also got itr shotpeened rods... think these will hold up to 300 hp?

 

i was curious what everyone thought about my setup...

im building a d16z6 as a budget street car.

im going to run some 12.5:1 JE pistons, some h-beam rods/arp rod bolts, p&p head, cam (havnt decided what specs i want to grind...) and want to spray a 200 shot of gas on it. i will have upgraded rail/injectors and a booster inline pump, running a direct port setup. Anyone see this being a problem? i may run a nitrous enrichment cell with 112 octane for the juice. obviously i will be running 93 octane on the motor.

does anyone forsee any problems? all the details havn't been worked out yet, so im open to suggestions.

 

200 shot wow i wouldnt recomend it. 112 gas will help,but even if you had lower compression it is still too much. i can only imagine 200 shot should be about 18:1: compression. with the 112 gas and 12:5:1 comp i say do a 100 shot the most. if your block was sleeved, and you had some better valves i would say you might get away with it as long as the fuel is tuned properly with and ems, but still not safe either way.

 

but i was spraying 125 on the motor, stock, with regular grade gas.... yeah, im upping the compression about 2.9 points, and im wanting to spray 75hp more nitrous... the only thing im worried about is actually burning the pistons...

How are you comparing the amount of nitrous to a compression ratio. What makes you think that a 200 shot would equal to a 18:1 compression ratio?

 

thats the same thing im wondering... also, if my kit is pilled correctly, and im using 112 octane, i dont think the nitrous would be a problem, but thats also why im asking ... im not positive

 

...one of the HRI coupes that HYBRIDKOOPHRI speaks about sprays 180 shot on 12.5:1 compression stock bore and stock sleeves on ecu..i know this as a fact i know the builder personaly and know the motor and car inside and out..so yes it is possible.. ...........also side note:isnt this the allmotor forum?

 

200 shot on 12.5:1 motor.. jesus christ. thats all i have to say.

i was also told if i were to get the je 12.5 forged pistons and new rods, that my skunk2 stage 2 cams would be too wild for the setup and the nitrous would just blow right by, not even having much of an effect... should i drop down to stage 1's?

 

nitrous raises your compression ratio big time, thats the main reason with going low compression if your going to spray some laughing gas.
if you want to have the best of both worlds high comp. and laugh a little go with 11:1:1 comp 75 shot ,ems,msd,injectors and boost the octane up i see no problem at all with that. im a person thats more into realiable mods other than stuff that ll give you power one day and blow your precious motor another day.

 

the stage 2s work great....on nitrous..ive seen people spray on stage 3s..u can ask HYBRIDKOOPHRI...he done it plenty of times with good results.
