Nitrous Express Kit ok if already at 20PSI?

[MikeT1982]

Hey guys, being new here I am unsure of how to word the title but here is the thought. I used to have a 1998 Neon RT with a Nitrous Express WET Kit, that I would run either 35,50, or 75 shot depending on what I wanted.

I recently bought my first DSM a 1997 Eclipse GST from a freind who owned her since new and didn't start modifying untill around 40,000 Miles. Now it has 86,000 miles on it. I just got done flushing all fluids, changing brakes, all belts including timing, new plugs, new fuel filter, etc, etc.

It currently has a Walbro 190, 625cc injectors, a Hahn Racecraft Super 20G turbo set to 18-20PSI, a Quaife LSD, and a ACT stage 2 clutch. Also an Apex-i Super AFC, wideband AFC, scanmaster and turbo timer.

STOCK INTERNALS.

It is dynoes at about 300ish wheel horsepower.

I am curious if I could get away with putting the Nitrous Express Wet kit on my Eclipse or am I pushing things.

I know I have more turbo to use, etc, but with stock internals, I really shouldnt my freind said. I guess I would mostly want the nitrous to make up for the long turbo lag.

Please let me know any and all opinions/suggestions/flames

Thanks guys!

Those pistons won't be able to handle much shot if you ask me. Maybe a 35 shot but @ 18psi that might be too much.

 

[MikeT1982]

Yeah i'm thinkin maybe i best leave it well enough alone. It really runs well, I got a scanmaster and checked for all codes like you guys told me to (instead of pulling the check engine light LoL) and all it was was the missing cat. So otherwise the car seems really healthy, and I don't want to damage it, so maybe I'll scrap that plan.

If you want a little more, open the boost up a bit.

Dont do it unless you have a good EMS like dsmlink so you can pull timing. With the boost, compression, timing, and nitrous, cylinder pressures can get dangerously high. Stock pistons, rods, head gasket wont like it. Could lift the head and blow the HG. To be safe low timing would be the way.

I would look into getting detonation down. Like running e85 if available or meth injection. This way you could run more boost and timing to make more power. That turbo could make 400whp on e85, race fuel or with some meth injection.

You are wrong. A simple nitrous express kit with a 50shot will not need the timing retarded. Colder plugs would be a must though. Although i do agree the safe way would be to lower the timing a bit. But personally i'd lower the boost to around 18and spray a 50shot. 18psi an da 50shot will probably yield around 22-23psi with the extra exhaust flow.

You don't think the boost, plus the 50 shot of nitrous would be too much on stock pistons?

On a well tuned motor? No. The key to nitrous is correct bottle pressure/temperature and good gas.

Is it a wet kit or dry? That 190 and those 625's are taking a beating so as it is...

 

[Burnett03]

Nitrous express only makes wet kits.

 

[JayRolla]

I wouldnt say Im wrong at all. High timing with nitrous is not good. The two things most people do is run one stage colder plugs for every 50shot and take 2 degrees of timing out per 50shot. So on a 100shot you would want a 2 stage colder plug and take at least 4* timing out the stock timing map. Its a good way to stay safe. On a stock block I wouldnt want to see more than 16* expecially on pump gas. But I guess this is just my opinion.

i am running 18psi boost on 20g and 100 shot but then again i have 7:1 compression.

 

[JayRolla]

How much timing ^^^.

 

[jerseydiver84]

id either run more boost and not spray or run less boost and spray a small shot, or build your engine to support both.

I will be running a 50-75 shot on my stock internal car on top of 23-25psi. Take it for what it's worth. I have an advantage of being lower compression though.

 

[JayRolla]

What timing are you planning on running. When I get v3 Im going to run a 50-75 shot also. Thinking of 25psi and 75 shot with 16* max timing should be ok for 8.5:1 pistons.

If you are talking to me, I am going to start around 14* and then just tune to a max of 17-18* if I am able to.

To op if you were going to I would at least put in a new headgasket, oem or cometic and arp headstuds
