turbo or no turbo. that is the question?

I have a 99 GS eclipse.(non-turbo). I WANT TO PUT A TURBO ON IT BUT WILL THE MOTOR HOLD IT? i HAD A FRIEND SAY IT WONT,BUT HE DRIVES A FORD.

In the 420a they can run 8 PSI no problem they break at around 12 PSI if the motor isnt built up.

What kind of turbo and what size do you suggest? This is my first eclipse more or less import?Whats a 420a?

that rite that should tell u that ur not ready to turbo ur car....U cant juss slap on a turbo buddy...requires more than u think! Especially if u dont kno wat a 420A is!

Im not doing it myself. Im taking it to my shop!! I just want to know more about my car and what they are doing!! Thank YOU!!!

Their is no such thing as just slaping on a turbo, a turbo is a fan that blows air into the intak and is powered by the exaust. You need to get a turbo kit, which is a set of parts that will adapt the turbo to you car, exaust parts, oil lines, charge pipes, fuel parts.

A 420a is the motor code for the motor in your car, 4(number of pistons) 20(displacment) A(first production type). Its also refered to a 2g nt, or second gen non turbo.

For the turbo kit, check out hahnracecraft.com, they are the prodomonant maker of 420a turbo kits. the stage 2 kit which resides at 8 psi will come with a s16g mitsu turbo and a fmic. Their are other companys out their that make kits for the 420a. Star which uses a external wastegae set up with a garret t3 turbo. Tsi performance found at needboost.com use again a mitsu s16g. SBR.com which uses a garret t3/t4 turbo (only for buit motors), conceptillusions.com which use a garret t3 turbo also. Hahn has the best quality and rep. Star has the best set up for high hp applications followed up by sbr.com, CI.com, and TSi performance.

For a shop to install a stage 2 kit expect to be charged some where between 800-1300.

Slow420a just the man for this thread

Damn Dyno-Man is evil as hell. Dude is just a Newbie asking a legit question. I know I had those same questions when I 1st got myGS.

Slow420a just the man for this thread

That guy is a freaking 420 animal!

If you ask me guys i say stay away from that engine. My advice is find a 4G63T from a junk yard. You can pick them up for like 400 bucks.. cheaper than a turbo kit anyway. Change all the belts and gaskets and hoses and you will be ready to go. In other words the 420a was not intended for a turbo so dont do it, it sucks big time and im sure slow420a will tell you all about it.

Edit: I forgot you dont know a whole hell of alot so im going to break it down for you. The 4G63 engine is in the evo and the turbo eclipses and the talon. These are known as DSM's (Diamond star motors). You should be very carefull with the engine you pick up if you chose to do it and if you ask me its a whole hell of alot better and will be cheaper. There are 2 types of 4G63 from the eclipse/talon. One is called the 7 bolt because of the number of bolts it takes to bolt on the flywheel. There was one problem with the 7 bolt and that is that the crank wasnt chemically hardend so its basically solft as butter and thats how crankwalk develops. Now its not all bad because the 6 bolt (found in older model eclipses and talons before 95. This 6 bolt crank is made from a much harder metal and i dont think it ever develops crankwalk. If you dont know what crankwalk is dont worry...all you have to know is it spells BIG trouble and you want to avoid it lol. Not all 7 bolts get crankwalk. I have a 2g with over 75k on it and it runs great. So i hope you understand a little better now. So conclusion: Stay away from the 420a... 4G63 (6 bolt) all the way!!!

Also... how much cash do you have to play with?

Not bad for a 15 y/o eh?

Ya except the 420a cant be swapped with a 4G63 motor it wont fit

whaaaa? Why??? Whats in the way??? I know people that have done it so... whats so different?

People have done it...It has only been done twice.

The motor doesnt mount the same really everything is differnt. It is way to expensive to make the swap that is why no one does it because your better off just buying a 4G63 equiped car from the start

those so called people lied. i use to hear just swap your motor for a gst motor all the time on the street , until i actually did some research.

yup people who know nothing about DSMs and mitsus will tell you that. The car isnt a honda where every motor can be swapped with each other lol. Main reason why is the 420a is a Chrystler\Dodge motor not a mitsu motor the 4G63 is a mitsu motor

HAHAHAHA. Nice kieth. If you want a good place to go for the 420a turbo kits then go here. They have been making them for a while and testing them.

the 6-bolt motors were in the cars from 90-92.5

sorry I was havin a bad day lol. I kno how its like bein a newb askin questions, everybody should, but like I said I was juss havin a bad day n also since b4 wen people kept askin the whole "can I turbo my rs/gs?" questions...that really kina annoyed me, n prolly everyone else....it juss got on my last nerve.

But newayz, like everyone said b4, 420's arent meant for turbo n plz dont try swapping to a 4g63 cuz it wont fit....n plz dont try the whole "well wat bout an evo engine?" cuz its the same thing only its oriented 180 degrees from teh GSX....belts are on the passenger side while in a GS-T/GSX the belts are on the driver's side. Same engine only oriented 180 degrees opposite...still wont fit tho lol.

The only model I've heard so far that can successfully carry a 4g63 engine...not to mention the AWD tranny...with sum work n money involved would be a GS Spyder. I think there has been SUM people that swapped from 420a's to 4g63's but i think they ran into sum engine problems or so I heard..not really sure.

lol what? THey only put the 7 bolt in the 95+... right?

nope the 7bolt started 92.5-99 from 90-92 they were 6 bolts and about half threw 1992 they started 7bolts

thought the spyder came with the 4g64 2.4L N/T and the gs-t spyder came with 4g63 2.0T

Okay so mitsu took the 7 bolt 4g63, changed the crank/bearings/rods, made a new cyl head for it, and called it the evo motor, which I see you hold in high regard.

Chyysler took the 420a, forged the rods and pistons, and extended the block an inch and threw the A855 head on and called it the srt-4 motor. The engineering and desigine is the same, the specs are different... kinda like the evo motor. Wow you were right the 420a wasent ment for boost, but same could be said how the 4g63 wasent ment to make power.

Dsm was disolved in 94, technically any car after 94 isant a dsm. Crank walk is not as common in 7 bolts as one may think. It mostly happens to later year spyders. And their are ways to prevent crank walk. Like not holding down the clutch for extended peroids of time, like when sitting at a light.

To stick a 4g63 in a 420a is about easy as sticking a v6 in it. Soo much has to be fabercated that its not really worth the cost.

I recomend that you read some of the stickys that we have for the noobs before you state incorrect information and other have to go behind you and correct your statments.

I have bought a brand new turbonetics turbocharger and a greddy stage II intercooler for my 420a engine, i was wondering, if i were just to put the turbo and intercooler on, and keep it on 8 psi, will the engine deteriate after a while or could i set it lower then that to save the engine. My boy said he would put it on the turbo for mad cheap but he doesn't know if the motor could stand up to it. Now he told me when he does it, install a manual boost controller and keep it around 5-8 psi and thats it, if more you are definitely going to blow the engine. But, i might keep it and save for the engine build up i don't know, due to the current situation i am in. I found after the accident i had with my vehicle that the frame in the back could be bent and the mechanic i talked to said its not worth putting more into the car, just change the belts and general maintaince if i want to keep the car.
