Direct Port N2O Install... - SRT Forums

JiM P 2001 · 02-05-2009, 12:44 PM

I just got my direct port kit and I'm trying to get together a list of parts I need to buy before I tear it down. I'm sure some have noticed, and all that have direct port know that the radiator hose and thermostat housing is a slight issue. I was debating running the t-stat housing through the chop saw, rotating the thing to exit on the other side of the power steering pump and welding it back together. Are there custom t-stat housings that a company makes already?

Can some of you guys with direct port post up some detailed under hood pictures? I searched and found a few but they are all sloppy installs. My goal is to make the nitrous install look like a work of art.

Here's the solenoids, nozzles, and dist. blocks:

I can bend the tubes myself. I just want to see pics of other peoples setups to see how the got around the thermostat housing / radiator hose issue...

Heres a couple

Using a basic fuel rail (stock 03 for example), and getting a Rage-Tech spacer for the lower thermostat housing would probably help best to make for a little more room

^^^^danmmm thats clean

jmf intake w/ Zex kit soft lines

i had to angle the nosles to the right, i test fitted then i had to use jb weld to hold the bung closest to the map/radiator hose so i could get it to the shop to be welded (kind of a pain)

EXACTLY what I was looking for! Thanks a lot!

One of my issues is my Perrin rail...

To bad you did not ask for pictures of a DP install that most looks like an octopus I'd post pictures of mine

TurboJack, that is a CLEAN looking install!

Rage Tech Thermo housing spacer should will give you that extra 1/4" or so you need....

That's pretty cool looking.

Everyone, the images I linked are not my car, they were posted in the DCR section and It's one of the cleanest port injection setups that I have seen on the SRT-4..........I just remembered seeing a while ago and when seeing this thread I knew right where to get the OP what he was looking for

That was my daily driver and show car for Mopar back in 2004! NX custom made the nozzle rails and kit for me.

Yeah, I was trying to find that rail setup... I think I may have a buddy of mine machine a rail with runners for N2O and fuel. I can't seem to come up with another way to make it look neat.

The sensor on the sensor on the passenger side of the NX rail, whats that for? It looks like a fuel pressure safety switch, but I'm trying to figure out which side of this rail is fuel feed.

That's what it appears to be. Fuel is coming in on the passenger side. Nitrous is on the drivers side.

I'm wondering If I can get my FP sensor mounted up here for my nitrous setup. Directions is to mount the switch close to the FP.

I just got off the phone with NX to get the proper jetting. I am having a local machine shop duplicate the rail from the blue SRT-4 pictured above.

I do have a question about tuning the nitrous. Right now I have a S2 computer, and no way to tune. I am running a -6 fuel feed and -4 return with an Aeromotive FPR. Currently the FP is 58psi.

I need to run the 1:1 FP:Boost increase ratio so the boost doesn't push back on my fuel pressure when I'm spraying, correct? (This is what I was told by Craig at NX)

If I run the 1:1 increase in FP, my injectors will now be dumping more fuel under boost, which means I will have to pull fuel. Will a MAP clamp solve my problem? I'm running out of cash for this project and need to get it done as cheap as possible without blowing my car up.
