Rebuild questions

[2gGhost]

So I'm going to rebuild the engine with my dad. I'm still in school. He's been doing this since before I was born. My ultimate goal is to go turo with the Hahn kit. How do I do a full performance rebuild. I have searched and researched and read that some use stock internals with the kit. Any thoughts? My thing is I want to rebuild the engine anyway do I know it's in good condition. Why not get it ready for the turbo. Thanks for the help.

If your going to run a turbo build. Dont run it without the turbo,. Atleast I would do that. I want to do a 420a turbo build (dont have the kind of money)

 

[3kgt2nv]

for the price of the turbo kit and the engine build you could buy a awd turbo car and have a better platform for future builds

I mean I know that but I kind of like the idea of having a built gs. Also I'm still a noon and I would rather make sone mistakes with the 420a than the 4g63t. Just want to build it to say I did it. So you think I should just do a normal rebuild and when I save up for the kit then do a performance build?

 

[DanGST]

Why spend money to rebuild twice? Just wait until you get the money to build it the way you want. It took me almost a year to build my 4g63t but it was worth the wait because all the parts are good quality.

Like stated above better and cheaper to buy a car with the 4g63. Stock 420a internals might hold like 5psi if ## lucky. I say go with a gst youll be happier in the long run..

 

[dsmpat95]

Build to your budget.

 

[2gGhost]

Definitely taking all this into account. I'm going to treat my 420a good. And see how I feel once I save up about 3k

 

[FearlessNick]

These guys do have a point. If your going to do a turbo build on a 420a. Might as well buy something that is AWD with a turbo. But I want to build up my 420a though. But still keep it N/T and have the fastest N/T FWD Eclipse out their. Its just based on what you want to do. People just come here for opinions. I ask for others thoughts all the time just to see what else I can do. But I go with the one I want to in the long run.

Yea I mean I see alot of gsx's in my city. I want to be known as the guy who drives the white gs that's built like crazy. Like do as much as possible then maybe turbo it. The gsx thin has been done before over and over. My goal is to build my 420a and later on when I feel I'm done get a Awd. It's more for personal satisfaction

Even if you build up your 420A, you still can be beaten in some instances by a well tuned GSX. There is a 661HP 420A here on the forums and i highly doubt its a DD car. You have to take in account of the prices of parts you would need to beat a highly modified 4g63. crank, rods, pistons, cams, head work, intake, exhaust, turbo, tuning capabilities... the list keeps going.

This engine is great and can have potential but the costs out weight the benefits im afraid.

Keep the car as a DD and pick up a nice 1G to build or a non running 2G GST/GSX/TSI

Im glad none of you answered his question...

Telling him to sell his car and buy a new one is not an answer. Selling his car and spending an extra few thousand gets him a 4g63 car with an engine running on 150,000+ miles, and probably stock form or beaten on. Now on top of the extra few thousand he now can add the cost of upgrading parts, replacing gaskets and worn stock parts, etc... ( Because every DSM'er KNOWS you do your basic maintainence Before upgrading) OR he could take that few thousand he was going to spend on changing cars and put it into rebuilding the 420a car he already owns and have a brand new 0 mile engine and new parts that arent worn.

A stock rebuild with stock pistons, rods, and ARP head bolts will be able to safely run 8psi, and upwards of 12-15 if you have a proper way to tune it instead of just running a 12:1 vortech fmu... ( Granted this all depends on the turbo you choose and its flow)


A "Performance rebuild" you can use all stock bearings, gaskets, stock head, forged rods and pistons ( the 4g63 comes with these from the factory which is why they can be cheaper to build since you aren't having to add them aftermarket to make big numbers). Then piece yourself together a turbo setup by researching until you think you know what you need, then researching more.

If your goals aren't stupid high you should be able to meet them with the 420a. The stock head flows well and has been proven to reach the 500whp mark. Personally if you are going to turbo just go with forged internals on your rebuild. It will only cost you an extra $700 to get a Wiseco/Eagle combo and you can boost until your heart is content with proper fuel management.


But yes, if you want to spend $2-3k more and get yourself a tired 4g63 car, and then spend money on top to upgrade parts go right ahead. The $2-3k you would have spent is more than enough for a forged rebuil plus a few of the goodies you'll need for turbo.

I left a lot out in terms of everything a rebuild requires, for sake of me not wanting to type it all... Research what an engine rebuild requires and you'll know what you need.

A gsx can be had for under 2k. Of course needing some work but that's a perfect opportunity to get better parts right away. I've had 3 na dsms and 1 gst and 2 gsx. All 2g.

If I were you I would dd the na. And the 3k that you want to spend on it. Save it and use it to buy a gsx. My fiance just bought a 97 gsx that was making over 300hp for 1600. Engine knocks. Overhauling the engine would cost a few hundred. Even the most expensive route-buy a whole running engine for 1k. Its still under 3k.

I know you said you want to be different. And everyone has personal desires. Most of the people on this forum don't have the same desire to build a 420a, so they're just giving the most financially efficient advice.

 

[afoster98GSX]

I would go 4g63 over 420a anyday.

Where can I buy a decent 2G GSX for under 2k? ( In all honesty because I'll buy it tomorrow in that case)There are barely any decent N/A 's here for under $2500 let alone a 5-Speed GSX... Anything under that and you're usually looking at needing body work (rust repair, peeling clearcoat, dents/damage ($$$ if you can't do it yourself)) and it has some sort of engine issue in most cases... hell I see non-running ones going for more than $2,500 in the classifieds right now...

I use my N/A for my DD only, and I'm getting ~34mpg. I don't hold loyalty to one engine or the other to be honest. These cars are getting old.. hell the newest is at minimum 12 years old.

 

[2gGhost]

Philly. Seriously. I've seen them for around 2 to 3k. Not too many miles usually around 130 140. and I definitely might just do some basic mods to my n/a for a little extra kick and save up for the gsx. When I stopped to think it made so much more sense financially right now. Maybe later in life I'll build my 420a

 

[2gGhost]

Should've read 99Redgs's response sooner. You make a really good point man

 

[ed1380]

Just have to look on Craigslist everyday. Good deals are picked up in a few hours.

BTW her gsx has 115k miles. No rust. Good paint. It was 1.5 hours one way though

 

[dustpan]

im about to buld a 420a for my first build also and i have the hole ego thing that i do want the fastest 420a in town with horriale paint fade and looks beat to shit

 

[ed1380]

Unless your town is full of dsm'ers Noone is going to care about the engine. People care about the car. So having the fastest 420a will only matter to the 420a folks. But everyone will care about the fastest car. Don't want to come across the wrong way cause I've had 3 420a's too

 

[dsmjunk]

i feel the same way bout my 97 it has the normal rot and it doesnt matter what it looks like as lon as its fast besides a lil less body is a lil less weight

 

[Josh97eclipse]

Keep the 420a its a good place to start. You should run egale h beam rods and eith wiseco or je pistons

 

[96DSM_Steve]

Hey 2gGhost just look around in the supporting vender sites and find the performance parts that you want to install. It's your car do what you want to do with it and if you get stumped on something all you have to do is ask and someone on here will help you. I have seen some really nice set up's for the 420a's. Check out some of the turbo builds on you tube that should get you thinking on what you can do to yours. Go for it and good luck.

Thanks again for the advice. Decided to build the 420a. I feel more comfortable building with the platform and the YouTube videos have gotten me excited as to what can be done with the 420. I'm thinkin buying all the quality parts. ie forged internals, ported intake, bored throttle body etc. Do I install piece by piece and run that until I get the Hahn kit. Or just wait? Thats really my only question right now?

 

[2gGhost]

Oh and I'm following the power upgrade path on the site
