500 Hp Neon Srt-4!!!!

I found this while doing some snooping around the net today. Looks pretty nasty. I have no info or specs on what type of set up it is. I would hope that the bottom is built. Will be interesting to see how long the motor holds up....

The turbo is a gt30/40 ball bearing turbo, tial wastegate, AGP FMIC, and bigger fuel pump. Otherwise stock.

As for a built bottom end, it's got one: from the factory.

impressive....

I would have to spray his little @ss if we were racin.

That's an impressive little bugger. :bow: for that SRT-4.

Yeah but will the motor hold up for 200,000 miles of hard driving with these mods?

that is nuts and it should hold up for many many miles no it looks like factory

Keep in mind that's 500 HP in a 2900 lb car too. You'd need more than 500 HP in our cars to beat it.

Can someone tell me what they were spraying in front of the radiator?
I am just curious? because they already had a fan or so it appeared. Sweet little car and It will definately suprise alot of people.:bow:

If I had to guess, I would say something simular to liquid nitrogen to help keep the intercooler optimal for cooling. I would imagine it's the same idea as the N2O kits designed to spray directly onto the intercooler. Or I suppose it could have just been water...


If everything in the driveline stays together, that should AT LEAST be a solid 10 sec car.


BIGREDJIM-

When I mentioned something about the bottom end, I was just curious. I figured Dodge would have put some stronger bottom end parts together for that motor, but everything has a breaking point. I don't know if they have a bottom end like for EX, a Supra, which many people have run 700-800+ hp on a stock bottom end, or if the srt's were just "re-enforced" with some better parts than stock for the turbo motor. Remeber, they're adding almost an additional 300hp to that thing...




Jon

The 2.4 in those has the same crank as regular 2.4's, but it has oil-cooled pistons, and I think the rods may be upgraded ones over a regular 2.4, but I'm not sure on that. The 2.4 is just a stroked 2.0 in the Neons which has proven to be a CRAP motor. I know a guy who had a 98 Neon R/T and he spun a bearing in the 2.0 at 55k, 10k after he bought it and blew a head gasket right before. He then found a 2.4 out of a stratus that was almost new and put it in there with a ported head, and the same bolt ons on the 2.0. Took him a month to spin a bearing in the 2.4 as well. Unless Chrysler did some serious strengthening in the SRT-4's (it's just a PT Cruiser turbo motor), I have a hard time believing those things will hold up very well. Those things are way over squared in design, so they certainly won't be the most durable at high rpms either. We'll see though. As much as I dislike the car or any other 4cyl, I do give it credit for running 13's stock at around 20k.

Jason

I'm sure the Neon guys will tell you different, but there's not a car out there, not even the Supra, that will take 500rwhp on the stock bottom end for 200k miles. I also gaurantee you that car has more mods than what Jim stated. There's a lot involved in getting to that kind of hp level...ecu...boost controller...fuel controller....etc. And there's no way the stock injectors will support 500 rw even with a larger pump. Also, what about the clutch, tranny, rear end, etc. If they're not already built, they'll need to be. Adding 300 rwph to a car isn't as easy as slapping on a turbo and fmic.

i know somebody who blew their tranny the first day they took their SRT-4 to the track.......... but from what i hear,the bottom end is well built and can handle close to 1000HP or something like that,same with Fords Cobra.

The Cobra's use the same crank as the non blown models. Yes it's forged and pretty strong, but I doubt that bottom end is gonna be as strong as a Lunati forged bottom end for a 383 LT1 which is supposed to be good for somewhere close to 1000hp. It just doesn't add up to me. I'd trust the Cobra with about 600rwhp provided you don't spin it past 6500, but that's it.

Jason The turbo 2.4 is bullet proof. So much so that the Turbo Stratus in Mexico is used for police vehicles. The factory crank, block, and head supports 1,000 horsepower. The factory longblock is likely good for 600+whp. There is absolutely no reason to believe otherwise.

What is this about crap motors? Other than the head gasket on 95 Neons, there are aftermarket Neons running around with 260HP without any internal work and 50K-70K miles after the turbo kits was installed. Heck, a stock bottom end 2.0 DOHC motor with turbo was running 11s for three seasons without any problem what so over. Now the driveshafts on the otherhand...

As far as the 2.4 turbo motor, much of the redesign/features for the Mexican motor are now used in the regular 2.4L, not the other way around. In fact, getting a regular ol N/A 2.4L on the cheap and slapping on a turbo is a great way to get solid power without much $$$.

To be honest with you guys..i know you will prolly run me off and ban me from the site..;) but i would love to own an SRT-4...i think they are badass little cars, and i guarantee that if a cop is sittin there next to you at a stoplight..he's not gonna think twice about lookin at a little neon with a wing..but if he looks over and see's a kid driving something with "Z28" or "SS" on the side...he's gonna be watching you a little more closely. Now would i take one over a Z28 or an SS?? Nope, never. But i will give credit when credits due..and those are pretty sweet little cars....especially for 20K

I wouldn't mind one... if I could get over how it looks.:yuck:
Get rid of the neonish look and the super wing and I wouldn't mind anyone seeing me in it.

It's still just a Neon to me. YUK !!!! I'll stay slow and look good...

I know....I've got one:). My point was that it takes more than just a turbo, wastegate, and fmic to run 500 rw everyday. There's a lot of supporting mods necessary.

How much whp and 1/4 mile improvement do the little mods do on these cars? Mods like slicks, full exhaust, full intake, ignition, boost controller, blow off valve, high octane fuel, etc. Not stuff like nitrous, bigger turbo, intercooler, etc.

Wow, that is one sweet SRT-4. I got to admit, I like these cars. I dont really mind the syling, I could do without the wing, but other than that I think they're ok looking. I think Sport Compact did a project car with an SRT-4 and put on a little Lip Spoiler, it looked nice. http://www.sportcompactcarweb.com/projectcars/0401scc_srt4/
The problem with these cars is that a lot of people talk trash about them but have never gotten a ride in one, or even seen one in real life! I have a freind who's into Imports and bashes on the "Neon" just because it's a "Neon," but has never even been in one. When I was taken for a ride in one I was very impressed. That thing was QUICK and it only had a Boost Controller and BOV.

Now, would I take one over a Muscle Car, no. But these are fast little cars, and because of that they get my respect.

Full exhaust is worth 20-25 horsepower. Ignition upgrades do nothing. Intake does little to nothing. Boost controllers are a waste, WGA are better. Blow off valves are worthless for power, the stock one works well enough. High octane fuel is worthless unless running enough boost or nitrous to need it.

Hmmm, I duno, but various people I've talked to including a guy who's a mechanic don't have any good things to say about those motors. I duno, maybe Chrysler beefed them up sometime with the last few years, but I've always been under the impression that Neons, Stratus', Avengers, etc in general were "one time use" type vehicles especially when hopped up. At least though there is now a low priced Detroit 4 banger that can run with the big dogs from Asia for little $.

But these cars are still Neons, which are fwd, 4bangers which is why I'll most likely never own one. But at least there is something out there that runs 13's for 20k. But the upcoming 05 GT is around 25kish and has 300 hp from those new 3 valve heads on the F150's. Those should be strong running cars, and then there's the Cobra...

Here's an article (http://www.sportcompactcarweb.com/projectcars/0310scc_projneon/index.html) on the internals. It's built. Here's another (http://www.hotrod.com/techarticles/engine/113_0309_srt/index.html) you can show them.

When you find a weakness in the engine, please let me know; because the SRT-4 community sure hasn't found any.

Anyone who thinks the SRT-4 isn't a stout motor is a fool. It may very well be the strongest 4-banger on the market. It may even be stronger than the Evo's 4G63 (Thank the Gods of displacement!).

The 500HP Neon ran a 12.1@124 mph on street tires, then broke axles! Looks like the weak link still...

Is there a cheap way to turn up the boost safely and get a lot of extra power?

That's what happens when you add 300 rwhp without fortifying the drivetrain. As stout as the engine might be, I doubt Chrysler designed the tranny, rear end, axles, etc. to withstand 500rw.

How much extra power does the WGA add? Sounds like a work in progress since it is throwing codes.

It's hard to say, since each car's PCM handles it differently. One of my friends has the AGP WGA on his 03, and with that and exhaust he was running 13.1@106.

I'm confused.

How is the wastegate controlled stock? Once you add the wastegate actuator, what sort of bleed valve do you use to control boost?

Nice! Those cars are growing on me, more and more. I just can't stand the wing on them. The looks are a little frumpy besides the wing. But it sure is a nice, cheap, fast, practical little car. Front wheel drive is nice in snow country, too. Is it easy to remove the wing and fill the holes that it leaves?

Yeah, axles were a weak link in the 1st gen vehicles as well. Once on slicks and full-out NA or go turbo, axles would start to go. Replacements include OEM PT Cruiser ones, not sure what's out there for the SRT-4 equal-length driveshaft deal.

I didnt read all the posts, but the car is here in Houston. He dynoed 502whp and ran a 12.1 spinning through 4th gear from what I heard. Ive met the guy a while back when it wasnt making nearly that power, cool guy. Theyres another black one thats supposed to be making 400+whp soon.

spinning through 4th gear??why didnt he just abort the run and try again?

My buddy has a Neon '03 SRT-4 and He and I did a race from a roll at around 30mph...
It was DEAD EVEN.
All he had was cold-air intake and a BOV.
He was shifting the thing like he stole it, which isnt good, but we were dead even. No pulling, nothing.
I couldn't believe it.
Those things are fast.
He admitted I would probably get him off the line, due to traction issues, but it was interesting to see that our rolling speeds were about the same.
Beware of those with slicks.. if they hook-up... its gonna be a good race.

All those mods and a nearly stock SRT-4 is keeping with your car? Sounds like something is wrong with your car. What are your track times and mph? Guys with mods like yours are running 12s at 108+ with traction. That should be enough to waste a nearly stock SRT-4.

It's bunk since when can you double the HP of a stock anything and not blow it up. The engine has a cast crank if the thing ran the number the crank would snap. Also listen to the vid it appears, that the car never got out of third, and if that's the case the numbers would be missed up 'cause of the gears. How would those tiny tires hold 500+ Hp High rpm HP or not they won't. How can the head,cam,induction,exaust, computer,etc suport the HP. Everything looks stock to me, their seems to be no changes ,at all made to the car. The car is too new for a turbo kit, so it would have to be custom, you'd tell that. Don't get me wrong, I think their awsome little cars, the ricers need to know america can build fast 4cycls too, but lets be reasonable. Show me hard facts not fancy vids.

The stock crank from the SRT-4 has been used in 800+HP applications. It ISN'T going to snap.

The heads and cams in most turbo cars can usually hold a whole host of power stock. They're rarely a limitation until you reach the stratosphere of horsepower. Most will probably swap cams though to aid spool on a larger turbo. I'm sure the exhaust isn't stock and the ECU has some sort of piggyback or is a stand alone.

All aftermarket turbo kits are at one point 'custom.' Most competent turbo shops can build a manifold for a turbo.

My point about the custom kit, was it would have to be custom, and would not fit so "pretty" that you could not tell it was there. Show me hard facts the stock cranks have be used in apps were they made 800+ HP. A engine is basicly a air pump, your not going to tell me, that a stock head can flow enough air to double HP. The only reason you change cams on anything is to flow more air. How does a cam change help turbos spool faster. The only way I knew to make a turbo spool faster, was to lighten the turbine, or use a smaller turbo for the app. And who makes a piggyback for the stock computer? why wouldn't you flash the whole computer? I'm not a fuel injection guy, so educate me.

Thats the case with the ecotec, B16, etc. powered 4 cylinder drag cars. They go through new blocks every 15-20 passes at the 1000+hp level. I dont see that 2.4L being any different. All that drag car has in common with the street car is the block, and if I read correctly a cast crank which I dont see holding up to 1000+hp. Comparing a drag car to a street car is irrevelant because reliability is not an issue. Not to mention that car probably has well over 100k in the chassis alone.

The owner of the yellow SRT4 has plans to soon try for 600whp but doesnt know how long it will last, if it all. He recently upgraded the tranmission, axles, etc. so he can run stickier tires at the track.

And do you, someone who apparently knows everything about the SRT4, have any proof otherwise? Im not going to bother to look it up, but I bet you anything Im right.

That 5.0 block(if it is still a 5.0) in your mustang wont last long much past 650rwhp(750bhp). An LT1 block wont reliably last long much past 1000rwhp(1150-1200bhp). So your telling me a motor with half the displacement from cheap ole dodge is going to hold together fine past the 1000hp mark?

The burden of proof lies with the one making the claims, not the one disputing them:)

What I was saying is that it's not up to meengreen to prove that it can't hold 1000hp....it's up to you to prove that it can (since you made the claim). If you offered proof, I missed it. Has anyone come close to a 1000hp on the stock internals?

No one ever said "stock internals". I believe it was the stock head, block, and crank. I know of several high-horsepower (700+ whp) DSM's that use the stock head (not valve train, though), block, and crank and do not replace the block every 15-20 passes. I don't see why the SRT4 would either.

Sorry, I was going back and forth between the "heads, crank and block will take a 1000 hp" and "the stock bottom end should be reliable for 200k miles at 500 rwhp" statements. I don't buy the second statement....and I don't think the crank will last too many seasons at 1000 hp. Don't know about the block. It'll have to be out awhile longer to get an idea on reliability IMO.

This whole argument is stupid.

Heck there are many stock block/crank combos out there that can handle high hp applications. Take a good 4blt main 350 chevy block for ex.

The point is that you're not going to go buy a srt-4 off the floor and make 1000+hp with the stock bottom end.

this whole time i thought we were agruin about the SHORTBLOCK. Who cares what the block can handle if the rest of the parts cant take the stress?
