Re: what do i need to tubro my neon

Welcome to TurboDodge.com, you've come to the right place. :)
I have a Neon motor in my van, I turbo'd it.. I've also turbo'd a couple other Neon motors. They're good to about 250hp/250ft lbs on the stock internals. Beyond that, swap in some Eagle rods and some JE Pistons that are all over that place on eBay, and you can make significantly more.
You'll have to keep the boost low on the stock pistons unless you can run E85 or some other race fuel.
You'll need a better clutch, swapping in a Walbro 255 fuel pump is a good idea, and depending on what fuel you run, you'll definitely need larger injectors.. I wouldn't bother with anything smaller than 55lb, even on gas, simple because the Neon fuel pressure isn't boost referenced, so the injectors start getting small fast as the boost goes up. The first turbo Neon I did used some 42lb FFV injectors, and they hit 100% duty cycle at 10psi..
Of course you'll need something to get the computer to handle the spark advance and fuel curves properly. Some people use the AEM FIC, most people just install a MegaSquirt, even the cheapest MegaSquirt 1 unit will do what you need with that motor, but I'd go with a MegaSquirt 2 just for ease of use.
Our vendor on this site, DIYAutotune.com sells both injectors as well as MegaSquirt units.

Re: what do i need to tubro my neon

^ good advice. I def recommend a 255 pump, that's a common upgrade. I'm working on a boosted 2.0 Neon as well. I hear 7-8lbs boost is the most an all-stock 2L should see. I knew a couple ppl that ran 8+ and didn't get any life out of them. Turbo size matters too. I have a couple lying around. One's huge (too big to mention lol), and the other is quite a bit smaller, basically srt4 sized. Smaller turbos spool up nice and quick, but have limitations. However, in order to put a big turbo to any use, you'll really need to do some work Otherwise the increased size is pointless.

While some people don't see the need in doing this, I know guys that factor turbo size into their builds from day one. Obviously, if you want to run something crazy like a 63mm, you'll have a little more work ahead of you. Set a goal, work towards it. Mine was a very reasonable 200-210whp before I started my build, those numbers have changed since then :p

Thanks for all that info that really helpful . would i need to get a crankshaft then to or gust leave the stock one in? is it a must for the new cluch? I was hoping to use pump gas if i have to use racing gas then i dont think i wana go tubro beacuse i dont really know were to get racing gas. Your van looks sick have you gone to it to the track ? if so what it run?



I was looking to go for a smaller tubro runing abut 15 to 20 psi not to shure what the hp would be. thanks

No, there are no alternative crankshafts, and the stock one has been pushed to over 700hp without any failures.
If you're planning on running 15-20psi on pump gas, you're definitely going to need the rods/pistons I mentioned. Check out Dodge SRT4 - Dodge Caliber SRT4 - Dodge Neon - Chevrolet Cobalt SS Performance Parts and Accesories, who specializes in high performance upgrade parts for the Neon motor.
No, my van is not a race car, it's just my work vehicle, so it doesn't go to the track, it weighs almost double what my Omni weighs.. I take the Omni to the track. I have a 2.4 in the Omni which runs circles around a 2.0.
A properly tuned 2.0 running 20psi on some good fuel will put out around 300hp, possibly more. (A 2.4 would put out 400hp at that boost level)

Yeah, 2.4's are great because you can use just about all of the SRT4 parts on them. You can run pump gas in any motor that is built to BE turbo. If you just grab a Stratus 2.4 and don't make any changes to the internals, you have the exact same limitations you have with your current 2.0. Don't cheap out, do it right.

Nope, no alternative crankshaft.. These aren't Mitsu motors, they don't have weak crankshafts.
Yeah, this thread will still be here, post as you go with any questions you have.
If you get a 2.4, try to get one from '95-'99, and definitely not '03+ unless you want to go full standalone with the MegaSquirt.. I'd only go '03+ if you flat out buy a full SRT4/PT turbo motor.

Yeah, the 2.4 swap into Neons is extremely common. The 2.4 will run on the 2.0 computer if you don't have a turbo (as long as it's a '95-'02 2.4L). Makes pretty good power too. When you get the 2.4, you'll want to swap your 2.0 camshafts into the 2.4, they're good for 10-15hp. You should remove the balance shafts as well, they rob horsepower too.

Heck yeah it's cheaper to just get a motor.. hehe, no, you don't need the whole car. I picked up a whole 2.4 from a nearby junkyard for $91 two weeks ago.. That was a killer deal, I usually pay about $250-$300 for a whole 2.4 from the JY I usually go to..

If the 2.4 is a '95-'99, yes, you can use a 2.0 headgasket on it. Timing belt is not the same, you will need a 2.4 timing belt. Gates makes a nice Racing belt for the 2.4 that's quite a bit stronger than the standard belt, and is priced well.
No, you don't need custom axles.
