Hi I going to try and swap my 420A for a N/A 4G63 motor. Im wondering how hard would it be, if i have to swap tranny aswell, and if it's easier to just have the car donating the motor would help. Now I'm 16 years old and i know that turboing a 420A would be better but i cant afford the insurance that comes with it aswell. So I found a Talon with FWD and a N/A 4G63 (owner sold turbo) but I'm just wanting to be easier to add mods to the motor in the future. Please leave me some tips on what i should and your opinions on what would do in my situation.

How would that make a difference? The insurance company is going to go by the VIN of the car so no matter what you do to it to the insurance company its still whatever the title says it is.
 
This has been covered. The two cars are not remotely similar and it's generally considered undoable or at the very very least completely impractical and alao beyond the scope of most of the people here. Listen closely. This is a major fabrication job. Please get the idea out of your head.
 
So would you think It would be better just to build the 4g in the Talon rather swapping it. The talon will need alot of work aswell, rust, door handles, and etc. The motor will need some tidying up aswell like the balance shafts are ruined, timing belt slipping, and the owner of it now sold the blow off valve.

You've got bigger issues than the blow off valve LOL. Speaking from experience, just enjoy the 420a for what it is until you can afford to do a 4G63 car right. I had a 98 spyder gs back in high school then got the gsx in college.
 
Well the car is only 400 dollars and soon to be scrapped. It and I think aswell their is gonna be a lot more than the BOV missing or anything else. It'll prolly be a long time before it'll run, and turboing my 420A would increase my insurance.
 
well I have to agree that swapping the evo 4g63t is no easy task and should be thought out beforehand...That said If you have the money and the means, it's not a totally out of this world swap, it can be done with the proper tools, parts and with the right amount of money, but at that point you really will have to make your car your own way.

I'm not going to lie if I had a shop and all the tools/skills needed I'd find a 420a and do the swap, but not all of us own the $10,000-$50,000 garage just yet,or know how to weld but future planing and having goals are always a good thing to have.
 
To swap in a 4g63 motor into your car would require so much skill that it is extremely unlikely you'd be asking anyone how to do it. The reason is simple. If you have that much skill in fabrication, welding, etc. You would basically be wasting your time asking.

If you have to ask how to turbo your 420a you likely don't have the skills to finish the job. If money is at all a issue for you, you don't have the budget to turbo your 420a. If you do manage to turbo your 420a it will likely cost you more to make the same or less than a stock DSM sometimes you can make more but not much on a stock motor. The 420a motor is weak, it wasn't built for power it was built to save you money.

If you want to go faster, getting a turbo DSM is by far the simplest and cheapest way.

If you actually plan on driving the car. How much do you really want to have the car down for weeks or months at a time because something cost more than you can afford?

NOTHING is as easy as it sounds. You can't just go a throw a larger turbo on the car. You have to make sure you have the right air intake for the size of the turbo inlet, you need to make sure your wastegate can support the boost you are going to run and if you need a internal or external one to do that, you need to make sure you have big enough injectors, a large enough fuel pump, a way to tune and a proper tune, intercooler piping that wont get in the way of your intake, you are probably going to have to relocate your coolant tank, want AC with a FMIC? well now you'd need a slim fan and a aluminum radiator wouldn't hurt, you'll need to upgrade your clutch to hold the additional torque, don't forget to do ALL the maintenance on the car before doing any of those parts, you will want to get a full turbo back exhaust, oh and the exhaust manifold and that does not cover everything.

If you want the reality of the situation. At your age unless you worked literally about all year and didn't spend a single dime of every pay check you might be able to afford to do the things you seem like you want to do.

D-bag 1 down the street may have turboed his off ebay junk and had his car running like shit for 800 bucks but the guy at the other end of the street spent 10 grand, did it right and has a truly fast car that is going to last him quite some time. But even the guy who spent 10 grand on his car knows it could blow at any time and a good chunk of that 10 grand would be down the drain for him to start all over again. Cars that are built very well have things go wrong on their first tune and blow up before you can even do your first proper pull.

I hope you know what you are getting into.
 
Boosting a 420a will not increase your insurance LOL. It's an NA car in their book. You can buy Cobo's turbo kit for $1500, comes with everything you need to safely run 8psi and you wont destroy your motor guessing about what you need to boost. Comes with .50trim Turbo, FMIC, BOV, Piping, downpipe, fmu, walbro 255, etc.
 
4g64 does not bolt in either. Same amount of work. This thread needs to be closed. This topic has been beaten to death since 1995.
 
Based off the question itself, I'm going on a hunch and figuring you are fairly new the scene and just learning cars considering your age. Give it time BUT an engine change of this nature would require a core support swap, belly band swap, wiring harness, and motor mount mods in addition to wiring harness and the 500 other ancilary items to make it go with a 4g63. That said, as much as I can say about what some would consider a "proper" 420a that could support any noteable power levels based off my personal experiences since 1999; you're best off to drive the 420a as is and look into a 4g63 car after you become more informed. Down time, knowledge, and $ are required to have a DSM. Don't be discouraged just look into changing the train of thought. You will be happier.

Yes, it wouldn't increase my insurance if my provider isn't informed about the turbo. But with that being said it will NOT be covered if it gets damaged. So I'm not going to dump 1000 bucks on my motor then it get crushed based on other's mistakes. But what I'm saying yes it does increase insurance if you inform them on the modification. The source of my saying of this comes from my insurance provider. But with that idea out I think I'll pitch the idea of swapping motors and still go through buying the Talon. It'll be a project car and won't be on the road for a while. The 420A will just be kept as a reliable daily since you can't get much or anything out of the motor. Thanks for you all commenting and inputs on the subject. But I will ask any questions any questions on building up the new Talon I'm going to purchasing.
 
If this thing is in that bad shape you are likely money ahead buying something else or salvagung this talon for parts. 400 isnt much but to try and make a good car out of something that bad is likely way more expensive than say a 2000 car to start with. As a learning project....fine, but before you go spend a bunch of money youve been warned. Ive probably got 5k above the price of my car in mods and that was NO repairs. Just mods.
 
If you say this $400 talon is junky then I wouldn't even get it. I'd get a better more reliable car for a dd..... Or walk everywhere till you get a turbod 4g63. And he's a tip... Why would you tell your insurance what you have? 1. It's gonna spike your insurance bc they'll think your racing it, 2. You think there going to give you what you paid for it? 3. That car is gonna crash and be totaled and they will most likely screw you and not even give that money. They don't care. Add ons from the factory is the only thing... Your add ons don't matter.
 
I put 250k on a 98 gs. Manual tranny. EXTREMELY reliable car. Not meant for power. If you want then you can turbo it with about 10 grand, to do it properly obviously. What i've learned: Never cut corners, get what you WILL want, not what's convenient. Do it right the first time.
You can apply forced induction to any car with a aftermarket tuning solution, it's all a matter of money. How much you want to spend
