need feedback on nitrous

Planning installing a 75 shot wet Zex nitrous kit, can the 2.5L motor and cvt tranny handle it? I wonder if anyone did this yet, any input is appreciated

If the trans can handle 4 large adults, im sure it can handle a 75 shot..



But the rule is start at the smallest shot and then work up.


This going to be direct or before the throttle body?



I would def get a wideband gauge just to be sure your burn stays correct. MTX-L is probably the cheapest and best. Im just sayin.. might need to tune for it based on the burn.



I would also get the blow down tube. and pray the burst disc works. Sometimes they dont and...

The same setup my brother had it tapped into the intake before throttle body, it sprayed when it was full throttle onm his built type r motor. He's going to install but don't really know about the camrys so he got questions I need to research about fuel pump ect...

Never done anything with nitrous myself but I'm pretty sure you can get a nitrous controller that can be programed to come on at any percentage and work up to 100% over any specified length of time. So for example, when it kicks in it comes on at 40% and works up to 100% over 3 seconds. This is supposed to be easier on the engine and transmission. Something to maybe look into.

The setup is going to be is, nitrous will engage on full throttle. Wondering if it will be good to also purchase an apexi smart accel unit for it?

Yep it is! Molsendavid is correct as usually usual. Really automatic.

But the Hybrids come with cvt's (ECVT). But, they don't count . . . . (here we go).

Thanks

Yes, but I'm saying when you go full throttle and the nitrous engages there are controllers that will engage it slowly so your drivetrain doesn't get hit instantly by a big jolt of power. How powerfully it comes on and how quickly it fully engages can be custom programed. Just an option if you are worried about your car being able to handle it.

Thats a good question as far as the pump goes.. IDK the flow rate of the OEM or if it will drop pressure when the NO2 is engaged.


Even a Walbro 190 lpm should be fine for your set up. the 255 is overkill



Also, Im not sure the TB is controlled by a throttle wire.. have you checkd it out?

I did an image search and it looks like the TB is electric controlled..


Now IDK about you, but either using a nitrous controller or tapping the tb control wire for signal sounds too risky for me.


but if youd like to venture on, You can always call Zex for tech assistance.

I have had experience with nitrous, just not on your application. Since it was answered that you have an auto tranny, I can tell you that you WILL want do two things to preserve it.
1) Get a transmission oil cooler installed. Before you start doing anything with the nitrous itself, this is very, very important. Your clutchpacks will heat-up between gears and you can kiss it goodbye. This is fairly cheap can can be done at most shops.

2) If you can, get a valve body job (shift kit). Or something else to help your car shift as quick as possible. The more time spent with your clutchpack slowly engaging for smooth, comfortable granny shifts, the hotter they will get.

As for the nitrous on the engine,

4 cylinders typically are good for up to 75hp shots. Start with 25hp shot. Then 50hp shot. I would not go higher than a 50hp shot with a dry nitrous setup. A wet nitrous setup should be good up to 75hp. I haven't read of any 4 cylinder engines failing at a 75hp shot, when everything is running well with air/fuel ratios. Not saying it can not happen but I haven't read about it. I've only used up to a 60hp dry shot on my Subaru Impreza (N/A-Outback Sport) but I also was running 5psi of boost. Never had any issues but I'd never recommend it.

I went and bought the transmission cooler then got the car jacked up but didn't see anywhere to hook it up to front the radiator or a stock cooler around, is it hidden under the cowl or something anyone know of this?

Also is this what a shift kit is? http://www.ebay.com/itm/Transgo-SK-U...lYstxh&vxp=mtr
