Nirtous (NA Power Stage 4?)

[Gothkid]

Ok, im sure this is a touchy subject, however it is hands down the most effective way and technically cheapest method of getting more power out of a car.

I'm strongly considering a 50 shot zex kit for about 600 bucks.(drive2)

i want to know, has anyone done this before?
with my car in particular? (08 2.3L Mazda 3 ATX)

also i would like to note, that nitrous will not blow up a motor if it is installed properly, used properly, and the fuel trim is kept proper. Its a matter of knowing what your doing, and not pushing too much.

Any stock 4cly should be just fine on a 50-75 shot. past that, you need to retune, build some internals up, and possible use a different head/motor. In contrast a built 4cly should handle 150 to a 200 shot without a problem.

i want opinions and maybe installation help/advice.

I am not trying to sound like a dick, but I am not sure exactly why you are asking? Based on your post you seem to already know the answers to everything you are asking. Am I missing something?

I don't know any 3 members running NOS. So goodluck. :Let us know how it turns out.

 

[GoFast]

yeah and take pictures

i see this going horriably wrong. i'm intrigued. hopefully it works out for you though.

just re-read the original post. you want to run a nitrious set up on a automatic transmission. good luck the mazda 2 and 2.3 automatics can't handle power. some kid turbod his auto 2.3 and brought it to my work (mazda dealer) he was running 5 psi and he went through 3 trannys. the clutch packs can't handle much extra power. we figured it was making maybe 160 BHP and it was more than enough to burn up the trans.

I might be completely wrong, but assuming that a 50 shot will add any torque you could very well exceed the torque capacity of the stock clutch and burn that out as well.

You might want to think about adding a new clutch and pressure plate to the bill.

Still, Im going with the consensus here, I want to see what happens.

car is an automatic, but good point

Thanks for pointing out the auto tragic. I missed that in the original post.

Gothkid, stick to the basic boltons and make it look good. There's nothing wrong with a show car (first)

160 bhp is only 4 hp more than stick on a 3......so im thinking that tranny might have had different clutch plates. i talked to the dealer about it, and one of the mechanics, the stock auto tranny on the 08 is supposed to be able to handle an absolute max of 250BHP. they said it might handle 300 but it will slip bad. ill be sure to post pics and dynos and track times when i can. thanks for the warning though. we'll see what happens

 

[mjthorne]

we'll see what happens

I'm looking forward to it.

dyno your car, those aren't the real numbers. advertised horse power is completly different then real hp. a blue printed 2.3 may have 156 hp. and as for the tech you talked to i don't know where he got those numbers from.even for fwd cx7s. which have 2.3t engine found thats found in speed 3 and 6s. that transmission will slip at 300 and its much beefier than ones found in the 3.

i'm not trying to discourage you by anymeans. but there should be things you look into to help keep your tranny alive. even if you switched to a mazda 6 transmission with a 2.3. a mazda 3 transmission runs at a max of 19psi. mazda 6s run at 28-21 psi. higer line pressure means higher force applied to the clutch packs, which means a higher holding threshold. i'm not sure if there are any companies make performance vlavebody assemblies but i'm sure with a little reaserach you would be able to find out. another option for a little added stability would be upgrading axles. not sure if thespeed 3 axles would work with an automatic trans, but i could find that out for you if you would like.

 

[Gothkid]

i will keep all this in mind for later down the road. for right now i have faith in my clutch packs being able to hold the extra 50hp. however, i do plan on going turbo a year from now, in which case ill work on upgrading the valvebody and axles before i try to push too much. thanks for the advice though. honestly im going to be using the nos so infrequently it shouldnt hurt the tranny too much.

 

[tsunami]

yes there are upgrade options for this tranny... i would also look at a tranny cooler those are relatively cheap and deffinatly help things out when you add more power.

http://www.nsnmotorsports.com/product_info.php?cPath=30_78&products_id=225 for cooler i can't seem to remember who had the other autotragic goodies... will try and figure it out.

 

[Gothkid]

thanks man, i will probably invest in that cooler soon. i know the 08 tranny was redesigned and beefed up a bit compared to previous years, but i believe it still operates at 20psi. upgrades would definitely be nice to keep it running strong. i plan on keeping it automatic, trying for the most nimble auto 3 out there. i want to use the car for road courses and autocross, and occasional drag, but not focusing on 1/4 mile times. thanks for being supportive, i was afraid i was gonna get flamed for using nos. any links for the tranny upgrades would be awesome. thanks again

 

[Gothkid]

well, the kit is halfway installed, i will post some pics when i get a chance, for right now im busy with homework, but i should be able to finish it this week.

However, you WILL get flamed for calling it "Nos" instead of "Nitrous". It just makes you sound like a ricer
