Well.. i have decided I might try the whole nitrous thing. Perhaps one of the advocates of it can help me out some (Nate?). Anyways, Looking to get around 660 to the ground on my setup. GT35, cams, intake manifold, etc, etc... The question is mainly about what exactly to buy to make it all work, be safe and pass tech inspections. The other question is the fuel system... will a Walbro suffice? I only have 780cc injectors but I also have meth injection (I figure I could spray the meth to help provide more fuel)... so would this work? I assume the 780s may not flow enough (Even if I set the base at 50psi)... I may be wrong though. The last question is about the intake manifold... it is Marco's manifold and Im wondering if this manifold has the pooling problem or anything I hear about... I dont feel like blowing the intake off the car

 

Go direct port if youre worried about puddling.

Bottle heater.
Pressure gauge.
WOT Switch
RPM switch
Fuel pressure safety switch
Colder plugs

Maybe an ignition upgrade.

 

So who can sell me a bolt on kit? I dont want to try to fabricate and guess on line lengths, etc, etc... I will weld up the bungs on the manifold but the rest of it I would love to have a 'kit' of some sort.

 

There is no difference in using Nx or a bigger turbo w/injectors. Both add more air and fuel into the cylinders. Problem is, no one takes the time to TUNE the Nx. Yes, the AFR's on nitrous must be tuned just like adding the turbo kit. Timing must also be carefully set. You need a wet kit. One that sprays Nx and fuel. Ive had a 75 shot for 6mos and no problems.

 

DSMMotorSports was going to make a custom Evo kit.

I really want him to also, I would buy it in a heart beat.

 

I am on the edge to setting up nitrous in my evo as well. Soon.

 

Well guys, since I took the 35R off my car, Ill be going back to the nitrous with the stock 03 turbo. My car is apart right now for another clutch (another act disk going in with the old PP).

once I have it up and running, need to retune for the stock turbo, then Im going to start working with meth/nitrous together for the street.


Trina: give me a few day, Ill work up a price to do a 4 port nitrous kit to use -3 stainless braided lines from the distribution blocks instead of the hard 1/8" lines you have to bend. That will save you atleast 2 hours in install time. and if you haven't tried to custom bend 8 lines to all line up and seal before, you will waste double that time and material screwing it up twice. obviously doing stainless braided flexible lines will install super easy, give you some variables in mounting the solonoids, and install super easy.

 

I saw your PM before, Ill get crackin on this again. The main thing is getting the right fittings to make the fuel connection.

 

Are you running that 75 shot on the stock head gasket?

Honestly with a boosted car you dont really need to worry about puddling.....25psi is gonna keep the mixture moving.

I would run a single shark nozzle just in front of the TB. A 75 shot is a bit much for more people since it acts more like twice that on a turbo car. I would stick with a 50 shot.

There is a difference between turbo and juice though....turbo's normally provide more power up top where nitrous provides more power down low. The flow of nitrous is always the same but as RPM increases less nitrous gets in the chamber for each compression cycle. At 4k RPM you get twice the nitrous you'd get at 8k RPM. Also first gear and nitrous dont normally play nice together.

What is the smallest shot you can run with a DP setup....I thought it was pretty large.

 

And also if you could find a nice location for the solenoids, make some brackets for them, and then get the correct length lines from the solenoids to the nozzle, that would be awesome. I am very serious about this so if you would like a deposit or anything to get started, I would be more than happy to provide one. Please get in contact with me so we can work out some details. Thanks!

 

Yea I would be interested in something as well.

 

^ Me too, lemme know how this goes, perhaps a "stealthy" install

 

My alky is going to be installed in trunk on left side behind the panel and the nitrous is either gonna be where spare tire is or in a custome sub enclosure made for hiding nitrous and nothing else haha.

 

Thanks man... I know you are a large advocate of nitrous and I have no idea on what Im doing when it comes to it... I am not in a huge rush for it to be done anyways... I need to built the motor for it to actually take it. I figure I could get 550-600 on the turbo alone without too much trouble so shoot a 100 shot or whatever and I assume we should be near or past the 700 mark. I dont see the stock bottom holding that for too long Yeah just keep at it and Ill pay ya for it (As it seems many others will as well)!

 

Shamus has been having good luck with his wet kit on his DSM and has done the 75 shot a few times with no ill effects. He is mostly running the 50 shot though. All on a stock block with about 150,000 miles. He gained about five MPH (121 to 126). I don't think we ever got it tuned perfectly though and didn't have any dyno time. The motor has held together now for two years of 23 to 30 plus PSI of boost and the EVO block should be even stronger although it wouldn't hurt to build it as your GT35R has can flow quite a bit more CFM. Be careful when using the NOS as it will raise your boost. The 75 shot was jumping from 24-25 PSI without boost to 30 PSI plus with it. I'm sure he would try to help you out with questions. Definitely start out your timing on the conservative side.
