ok, so your core is 20X7.5?? I got what i thought was an NPR from a local turbo shop (Michigan Turbo. mostly Semi truck stuff) for $250. i'm sure it was used but he pressure tested it and painted it black. It looks exactly like the ones in the pics posted above, except mine has a 24X7.5 core. what size is the "big"one??
 
Okay, now i'm confused. Maybe I did get the smallest one. The core (not including endtanks) is said to be 20"x8.5"x2". It has 16 rows, and a 2.5" inlet/outlet.

Here is the one that's on it's way to me right now.

It looks like the other ones. :confused: Maybe they look close, but aren't? I'll have definate measurements soon.

Here is a pic I found of the large one, the monster.

These are the only 2 commonly used ones, people call them the large, and the small. I have the one people call the small. I don't know anything about the other one, which isn't commonly used.
Maybe it really is the medium. Shoot.

That's wierd. I've gotten several from this guy and they are all the same size (24X7.5X2). Do you suppose it's not commonly used because it doesn't fit well? or hard to find?? Mine's going in my GVR4 and it is gonna fit perfect [fingers crossed].
Really, does it matter?? for the price, whether it's 20 in. long or 24 it's still a hellauva deal, right?? and that's what we DSMer's are all about:D
 
$400+ for a NPR

man. I should kick myself in the ass right now. I bought a NPR (medium) about a year and a half ago from a junk yard for $30. And traded it for a AutoMeter EGT and probe since I blew my motor a week later. But I have a Green model on there now with the stock IC:eek: . so this would come in handy right about now. I wonder if they have anymore...lol...

*its funny as hell too how I came to aquire it. I was looking with my freind for a 350 (he has an S-10). We found this cammero with a nice motor and went to go pop the trunk (just looking around) and it was just chillin right in the center clean as can be and not a dimple on it. So I ask the guy how much he wanted for it and he said, (with his heavy ******* southern accent) "Oh that peice of junk...hum...30 bucks..i guess." My mouth just dropped:eek: . rushly payed him and ran off..........hehe..

Allright. My fault. I was unknowingly including the end tanks. I just measured it and the core itself for the medium is 20" long. 24-25" total including the endtanks (endtanks slope out a bit). I think the total length for the small is 20" so the core is probably 18" or so. The small is next to impossible to find so far. I haven't been able to dig any up.
GST2EVO don't feel too bad. I sold my first one for $125 shipped when I could have got a good $250. It didn't fit my 1G easily so I gave up. A few months later I had the 2G,a nd it was obvious right away it would have fit this one if I kept it. Live and learn.
 
I think they're not common because they're harder to find. :confused:
You're right, though, I guess it is still a good deal. :) If mine is 8.5" tall (although it very well might not be), then it makes up for it anyway.
How many rows does yours have?

BTW, I just checked, in PSP, the front view of two different pictures of two different "small" NPR's (mine and another), and they are both about 41% as tall as they are wide. 8.5/20=.425x100=42.5, or 42.5%, so that must be the right measurement. :confused: I just want to know! (I think i'm a little impatient). :D

We found this cammero
I'm sorry but i'm going to have to correct you now. It's spelled Camaro. :) I love them more than anything and it just bugs me (for some reason) to see it spelled wrong. It's like spelling Eklips. No hard feelings though. :D

Yeah, on one hand, you should have kept it, but on another, you got a good deal on the EGT gauge. I don't think $180 shipped is too bad (what I paid), just look for another. :)

And my above post was posted before I saw that. :D
Thanks for clearing that up! :)

OK, i'm on crack. I just measured it....it's 20 in. long.
 
First, i'd like to say sorry colonelfox, I really don't mean to post-whore your thread.

I got my NPR I/C yesterday finally (FedEx is slow). It really does dwarf the Starion I/C I had, and it is light too. You can also see light through the fins more clearly than the Starion, which means better flow to the radiator.
I did the ghetto efficiency test. :) (If anyone cares)
I did everything the same as I did with the Starion (read above), and the results made me happy.
As I said earlier, the Starion lasted approximately 5 minutes before it was extremely hot, inlet to outlet (same exact temperature).
I hooked up the NPR and turned the blowdryer on full blast, and once again, cool room temperature air came out, but slowly got warmer as time passed.
The air never actually got as hot coming out as it was going in, and I don't know if it ever would have just from the cooling effects of the room's temperature (about 70). After 11 minutes it was finally really close, so I just gave it up. By then, the inlet tank was so hot it was like touching a frying pan. It actually turned my fingers red from just tapping it (yeah, it hurt!). The outlet tank was nearly as hot, but I could hold my fingers there for a second before it started to burn (After heating for 11 minutes).
I'm sure a big Spearco or something is way better, but at 3-4 times the cost.
I'd say screw the Starion and get an NPR to everyone who wants a cheap FMIC. I found mine for $180 shipped, and i've seen Starions go for $200.

I took a pic of it behind my under-construction '97 Talon bumper just to give an idea of what it will look like. The gaps on the sides will be mostly filled in with the factory '97 foglights, and it will look really good I think (and yes, i'm going to get another huge Eagle emblem, because I like it).

I also took some exact measurements for those who want to know.
The core (no endtanks) is
19 3/4" wide,
8 1/2" tall, and
2 3/32" thick.

Overall, it is
22 1/2" wide (at the bottom)
27 1/2" wide (at the top, not counting pipes)
9 1/2" tall (not counting the mounting holes, which could be whacked off if needed)
2 3/4" thick (not counting pipes)

I hope this information is useful to someone out there...
 
ALLTRBO,Do you plan to take a different rount on the piping or do what colonelfox did? Can you post some pics of the install...I'm trying to track down a NPR IC myself.If you know where I might be able to get one.PM me the info.Thanks

Yes, I plan on rerouting the inlet/outlet to point straight out (away from each other). I'm going to do this because I already have full 2.5" SS IC pipes from the turbo to the TB, going the short route (not installed yet). They're the Victory Performance pipes, slightly modified. Besides, I really wouldn't want to do it like he did because I don't want to have the ground clearance issue of going underneath like that (just my preference).
I found out that my friend has a welder, it might be a TIG, so i'll see if he can hook me up for cheap (just on the welding, i'll do the modifying).

I will take full pics of the install, but it might be a while (maybe a couple months), because I need to finish my '97 front bumper first so I can line everything up properly. Then there's misc. little stuff that has to be done first also (busy busy busy).

I don't know where you can get one specifically, but I found mine on DSMtrader, and they sell on ebay too.

Hope this helps.
 
I'm bringing this old thread back out of curiousity (oh how time flies!), has anyone else used this IC since then, and what were your results?

I've since ran an 11.9 and 117.7 mph with this IC on race gas, and previous to that, it made the official T25 record with a 13.1 @ 103, both in cold weather. It's definitely great for the cost, but I think it's time for me to upgrade now as it's a bit smallish for my current setup in hot weather.
 
wow, this thread brings back memories. I have been using my NPR for a little over a year. I haven't been to the track with it, but i did make a few runs with the scanmaster "et" function the other day. In the warm weather the car felt fast (50 trim, 16-18 psi, 93 octane), but it was in the 30's on thursday and the car felt scary at only 16 lbs. I think the NPR is a bit undersized for anything more than i've got, but it sure liked the cold weather. I've always figured it was a restriction in the upper RPM's but it looks good in the front bumper and it seems to work just fine if i'm not doing back to back runs in 90 deg weather. The scanmaster gave me a 12.78 @108 on 16psi (GVR4 full weight, with normal junk inside for a daily driver, and winter tires :D ) I was extremely happy with that as i haven't had any time to mess with the MAFT (my mileage hovers between 12.6-14.6 mpg, so i know its a bit rich). All in all, not as impressive as your 117, but it was my first time actually using that thing for anything but keeping a watchful eye on engine parameters (the scanmaster that is). I'm sure i could get a low 12 on pump gas out of the NPR. I'm happy with it.

Mine has always been more than adaquate. I had to JB weld up a hold in it, between the fins and very tricky to get to. It's held up for a few months but otherwise it's been no problem. It seems to be doing it's job at 20-21 daily PSI on a 50 trim. No dyno #'s yet as I'm tracking down some other bugs and tuning but it keeps the intake temps down enough from what I can see. Never feels hot after a hard long run and knock (timing) and EGT's are always well within the limits. Fitament was straightforward. I chopped about 1 " off the outlets and pushed it as far up into the bumper as I could. I cut welded and angled some pipes just right and they've also worked fine for the most part. I did rip both of them off one night coming out of an alleyway a little faster than I should have. I have some undercarriage shields fabbed up to keep that from happening again. Just have to install them. All in all I'm happy with my $100 FMIC investement.
 
ALLTRBO said:
Cool, that sounds about right. Did you modify the endtanks any?
Nope. The inlet/outlets were setup perfectly for what i wanted as far as short route piping. a couple of GVR4's that i know of with the NPR mount it upside down, but i was able to trim a bit of the headlight bracket on the pass. side and run the pipes on either side of the radiator. It was a tight fit, but there is no shorter/ direct way to do it. It does, however, make disassembly a bit tricky, but oh well.
 
I have been running my NPR for 3 or 4 years now and have had alright results with it. I only had to trim a very small amt. from the Stillen bumper, little from the bumper support, and did not touch any metal in the radiator support. The only problems I have had with this I/C was the pipeing before I had the in and out pipe rewelded. I had a buddy reweld them ($25) and now they come out @ 90 deg, instead of the 45 deg. when they were stock. Have not had any icp ripped off since. Well worth the $25 to have them rewelded. Have not had dyno time since the 50 trim install but did put 290 down with the 18g (pump gas with around 22psi). Would say this I/C is well worth the $$$$ though.
