Turbo Neon or Nitrous Neon?

[gutted]

2.0 SOHC Neon (unless someone has a 2.4 they want to sell me cheap)

I need to decide what to do with it. I have two trains of thought at the moment: nitrous and turbo.

I already have lots of parts for an n/a car which could be used with a nitrous set up.

The turbo set up I would have to start from scratch as well as do lots of research (or just copy Devin).

Ideally I am shooting for 12s in a car more gutted than my last one. I'm thinking nitrous would end up being cheaper since I already have half the motor, and I would only be spraying when I wasn't bracket racing...

And don't suggest I get a Mustang or F-body :bash:

i think that a turbo neon would be much more respected cuz to me its so cool when i see a car and i think hmm small engine blah blah blah and i hear vroom pshhhh and ts like fuck yea but u hafta make sure that ur serious about a turbo set up cuz ive seen some go wrong...but thats wat devin is for.

a nitrous n/a is also a good idea and may be cheaper cuz u have the parts already, so if ur tight on money or such or looking for an easier way go nitrous.....

to me the turbo neon would be very respectful but 12's in any way nitrous or turbo would be highly respected anyway u got there! especially in a neon!

my 2 cents, do what u please:thumbsup:

Although I think a turbo neon would be really cool, it would be even cooler to see a 12 second juiced neon. I just would find it cooler to see a big puff come up from the staging area "PSST PSST" and then see a 12 second run. Turbo is cool too, and realistically a lot more friendly to having the power there all the time. But, I would just LOVE to see it juiced.

If budget is a concern, I 'd say spray it. If money is no object, go for the boost :cool2: Bear in mind that filling a bottle costs $40 when it's empty. I know someone who spent well over $400 on nitrous refills this year alone. Course he was using it constantly... :D Either way should accomplish your goal. How much you wanna spend and how often you wanna go that fast?

why dont you try doing turbo AND nitrous? what would be the prob? simple turbo setup, with say a t25, and a simple nitrous setup.:eh: but if you just want speed for cheap buy nitrous. it makes more sence financially

i hope he was only driving it in good weather, cause 10 bottles a year wouldnt be enough for me lol. :thumbsup:

heh. you've never actually put together a "simple" turbo setup, have you?

not trying to call you stupid. but there really isn't any such thing as a "simple" turbo kit. not without a TON of homework and a loss of a ton of reliability. you can have fast, reliable and cheap. you can pick two. but never all three. unless you are on monster garage and get tons of freebies...


nick, if you're really thinking about either, you KNOW how much homework i've done on both of them. copying my exact setup would probably run you around 4 - 5k or more... if you got a progressive nitrous controller, we could get you running 12's on that for less, i bet. just a matter of doinga lot of math to figure out torque loads at rpm points...

shoot me an IM later and we'll chat.

"boost is for wussies, nitrous is for cheaters" anyone wanna guess who used to say that all day? ;-)

btw, i'll juice mine when i get the turbo up and running the way i want it :thumbsup:

nah man, maybe simple was the wrong word. i just meant something basic (<---better word). i guess it depends how much he wants to spend too. to get into the 12's its either a crazy shot of nitrous, a crazy t3/t4 turbo setup, or turbo AND nitrous with not as crazy setups:eh:

will a 2.4 exhaust bolt to a 2.0? would a stock SRT-4 system bolt on is the real question? there are people upgrading so you should be able to find the stock system which should be good for 12s in a gutted car

the 2.4 and 2.0 dohc heads used in both of those applications are very similar (the same casting number, in many cases, actually). long story short, the srt manifold/turbo will bolt to the dohc head used on the 2.0 neon. the ports are bigger on the manifold, but that's not gonna cause a problem. two of the bolt holes don't seem to line up either, but that's not a big deal either, as nobody's had a problem with the manifold leaking or falling off either.

so yeah, in short, it's been done, and works just fine.

thing is, with this car it's not the turbo or exhaust that needs the most attention, it's the fuel system, and getting the car to run right under boost conditions fuel-wise. like getting the ecu to not freak out when the stock MAP sensor sees a boost condition, etc...

can you use the stock sensors and pcm from an SRT?

Budget is a concern. After having one car totalled, I'm bit leery about dumping tons of money into one car again. Plus, school is a priority.

The way I see it, I can do the nitrous build up for around $3000. I already have the top end, header, and intake. I'd just need to getthe kit ($1000), controllers, fuel, and bottom end ($1000).

I would love to do nitrous and turbo. However, I don't have the money to build a motor for both. I'm not ghetto rigging any thing. I'm also not going to pray the car makes it to NED and back each time I want to race.

If I would ever spend the time to build a turbo system, I would want to do it right, and not waste my time with a T25.

That is actually what I am thinking. My head + built bottom end + progressive controller should = 12s.

wouldn't want to or need to.

i'm not quite sure how to field that one, matt.... what are you referring to, here? :thumbsup:

if you are going to do ANY serious power adders to the 420a, rebuild and upgrade the fuel systme. FIRST. JE 8.8:1 pistons, eagle/crower rods, etc... then get a nice adjustable Vortech regulator or something equivelent and some 30 lb/hr or greater injectors.

turbocharging a 420a is crap unless it's rebuilt. been there, done that. it's like skating on thin ice unless you have experence tuning a boosted neon/2gnt before and you have access to a wideband. if you have it REALLY tuned right, you can push 10-12 psi intercooled, using a 16G, on stock internals. the piston ring landings always go first around 13+ psi, but some people have mananged to use the stock rods at 19 psi... don't ask me how because i don't know. i cracked (blew a hole in 1 piston) 3 ring landings at 10 psi around Thanksgiving 2002, but i didn't have it tuned right by a long shot. those were the days when i thought all i needed was an EGT gauge and a blinky A/F gauge...

nitrous is also a little tricky. you'd obviousally have to get a wet system, and i wouldn't go any higher than a 75 shot. watch the system like a HAWK. again, get a real wideband. i have the DIY-WB controller from http://www.diy-wb.com. tuning with just EGT and the OEM narrow-band oxygen sensor isn't very accurate. you'll either end up running really rich and wasting all of your money on gas, or running lean and cracking those piston ring landings. don't listen to anyone else about this. again, been there, done that.

everything he said, and then some. ;-)
