I want to turbo my car what I need to know is what do I have to have I only want to boost 6-8 psi. If I get a turbo ,exhaust manifold and the lines what else do I have to have do I need a fmu 12:1 or a mega squirt to be able to do it

sell it and get a gst or gsx it's not worth it

crap engine that won't handle it

sell it and get a gsx it's not worth it
:thumbsup: fixed

yes no fwd, and if you must get a dsm get a 1st gen eagle talon or eclispe gsx awd

Check out ebay look for full turbo kits required, you'll need whatever size turbo you choose even stock GS-T tdo3 will work fine, pick up oil lines, turbo fuel pump, downpipe, manifolds, SAFC for tuning, wastegate, pick up some stock gst/gsx injectors. Manual boost controller, EGT Gauge, you should have no problem running up to 8lbs of boost with correct tune.

Understand your probably going to blow close to $2000 for this and thats considered cheap if you do all the labor and tuning yourself. Personally I'd just buy a 1st Gen TSI AWD for $2-3000, and with BPU you'll be in the 14's 1/4 mile.

A 420A with 6-7lbs of boost is still really damn slow.

+1.
and not reliable. the motor can barely handle the power it makes on its own, let alone more power.
you runnin a single or dual cam 420a

hahn racecraft has been doing this for a long time. I won't give you advice about rather or not to do it. You decide for yourself, but they can do a lot for these engines, including selling you new rods and pistons. They have pushed neons to the 9 second mark with the same turbo system. As you may, or may not, know this is virtually the same engine that is in your car. Like I said, you decide for yourself if it is worth it.

There is a lot of misinformation about the 420a motor. Most of these cats don't know a damn thing about it, despite what they may claim. For example, the single cam motor has the same number of valves (4/cyl or 16 in total) as the dual cam does. I have fought, countless times, on the internet with people about this. It is true, regardless of what jargen people throw at me about why it is impossible. It is a fairly odd design and most people are unaware of the way it truly works. I promise you that this motor can, in fact, handle 6-7 psi despite what some people are claiming. The guys at hahn run more than that with stock bottom ends on pump gas for their daily drivers. If you want to run more than that though you are going to need forged rods and new pistons. Not worth the money to go that far in my opinion, but the choice is yours. If you do this you are looking at having a fun daily driver, but not a world beater by any means. It would cost a small fortune to build a truly fast car with this motor, especially considering that your car is heavier than a gen 1 neon, which is what most of the fast 420a's are in. Look to allpar's web site for technical diagrams that prove the valve concept, and just for more info on the 420a in general. This motor is a mopar design, keep that in mind when you do your research.

The biggest reason that people bag on this motor is due to the faulty head gasket that the early neons were equipped with. A very easy fix by the way. I am unsure if this would be an issue on your car, but you should look into it. It is the only fault in an otherwise strong design. Also, unlike other motors in its class, this one actually has torque at a usable range. The parts for this engine are also readily available at junk yards and in the aftermarket. It is a cheap build if you do it correctly, and very cheap to repair as well.

go for it, turbo the bitch. seeing a smoke screen pouring from the back of an eclispe always makes me smile

+1 WTF do we know. This guy obviously knows it all. That's why every neon I have seen on or off the track has been running sub 15's......:rotf:

I very clearly said that these engines did not make much power. I was just stating what they could do, which is handle about 6-7 psi on pump gas without modding the butt end of the motor. I never said it was a good idea, in fact I pretty clearly implied that I wouldn't do it myself. I would rather take a big block and actually make some real power. I just happen to know a bunch about 420a motors because I own a gen1 neon and I tend to it myself. I wouldn't turbo mine, but it can, and has, been done very many times. Perhaps if you go back and read what I wrote (I know it is a lot to ask but just give it a try, YOU CAN DO IT!) you would see that your post was off the mark.

i've turbo two 420a's. a single cam, and a dual cam. and NO ONE here said anything about them ahving the same number of valves. any idiot that can count and has popped the valve cover would know that.
even if you replace the head gsaket, buy the turbo kit, and upgrade the rods and pistons, you will have spent more money on that motor than it would cost to drop a 4g63 or World Engines 2.4 in there, and still be at the same performance level of the two.
ITS
NOT
WORTH
IT!
every, AND I MEAN EVERY, 420a boosted motor i've seen dies. you will blow the motor if you leave it stock, you will waste your money if you build it.

I agree, and I even said that it wouldn't be worth it for me. I also never said that anyone made a claim about the number of valves. I was simply recounting one of the piles of misinformation that is out there for these motors as they are many. You are also a bit spoiled when it comes to performance and mechanics and you know it dude. Most of us will never have the opportuinty to work on or drive much of the stuff that you have, so we have to settle for what we can get our hands on. Somehow I am doubting that this guy wants to do an engine swap. If he does than good for him, but most dudes won't do it. I was just trying to give the guy as much info as I could about the motor, as it is something I am familiar with. It isn't as though giving him info is going to hurt him, in fact it will only make him more wise. I just thought he might want to read up on the motor before he did anything with it. That is how we learn, is it not?

I have known several people that have daily driven their stock bottom end neons with hahn (stage one) kits on them. I will admit that they drove them soft on the street, but I know they can handle at least 6 psi on the track regularly on pump gas, as I have seen it done here art Stanton quite regularly. The guys that run neons at the mopar nationals can do some pretty amazing things with N/A neons as well. I hate to say it, (don't really want to insult you) but I doubt you or your mechanics are experts when it pertains to this motor. I also wonder what kind of shape those motors were in when they were turbo'd. I am sure they are very experienced with motors in general, but I know this motor can be used, it just needs to be set up properly. Also these cars have been running in the SCCA since the begining of the neon, and they do quite well stock n/a, unlike what some people are claiming in this thread. When can go back and forth about it all day, but we will not come to terms on the matter I think. The proof is out there, as it has already been done.

All that being said. You are probably right, it probably is a waste of money and time. Some people do it because they love the car they have though. Like I said, I wouldn't do it, but if he wants to then let him. The only thing I would consider doing with my car is to shoehorn a SRT-4 motor in there lol Even then it wouldn't be worth it to me, seing as how it is wrong wheel drive for drag racing and would wheel hop like all bejesus.

I wasn't calling you out either. You are obviously one of the very few knowledgeable people on this site, but some of the comments on this thread are nothing more than drivel related to one ignorant bastard from another. I hate listening to people just call something crap when they know absolutely nothing about it.

Listen all cars suck, end of story there is no perfect motor/car in theory. Yes its possible to turbo the 420A, yes some can be reliable daily driver, and yes few can handle up to 8-10 of boost. But in the long run is it really worth your money and time.

Im telling you even with 8lbs of boost in that car it will leave you dry wanting more power, invest in a better car from the start it will save you a lot of stress in the long run.

When you turbo your car, you enter a forced induction cateogry and if your looking to race I'm telling you no one will be impressed with a turbo 420 still barely touching high 14's, lol especially those N/A Civic enthusiasts.
