making an engine TURBO worthy...

I've been talking to a pretty smart guy lately and he's beein giving me some pointers on what to do before i drop my turbo kit into my car... so far i've gotten: fuel system, throttle body, connecting rods, pistons, injectors, crankshaft, exhaust, and ignition... anything anybody else can think of before i put a HAHN Stage 2 Turbo kit in my car? would i need to drop a new trani and clutch also??? any help would be appreciated

big horsepower will gradually wear away at your tranny, but even regular driving will do that. hahn would know for sure, but i am not, whether or not sleeving the block is needed. youll also want some small things such as new head bolts, but that is a given.

i would think that you would also want to have your head ported and polished to make more room from the added air...

still looking for help

rc im sorry man i dont know who agrees with me or who doesnt but i think its ludacris to do all that work on a gs when you could grab a gst and just upgrade the turbo and some small other details (fuel blah blah) and be way under what you will spend for turboing that gs... you can run all the power youd ever want to run on the gs-t internals.. the 4g63 is an incredably strong stock motor.. you will save THOUSANDS... in my opinion on your car you will have to swap out/rebuild the tranny.. clutch.... the gs isnt a sports car.. its not made to take what you want to give it and/or how your going to drive it..

I costs a royal load of money to convert an n/a eclipse to a turbo. In fact the only reason we did all of our mods to the '97 was it was danm near fee. I want to say the final tally on engine cost alone was slightly over 7-grand...... and there is no labor included in that since we did all of the work ourselves. It really was not all that cost effective which is why I am pondering the VR4-TT swap for the '94.

how do you figure? first of all a gs-t/gsx will cost 3-5 grand more "based in my area and most areas ive look for them" which will almost cover the cost of making the car with a new strong turbo ready motor and maby a turbo kit and than you will not have to spend the money upgrading the stock kit "almost like buying 2 turbokits". and the tranny wont need to be replaced or worked on until over 300hp. and the gs-t motor you would buy would be used and a possably an abused motor that might blow up. and i dont care if it is a 4g63 the more boost you put on a motor any motor it will whear faster. so why not do it on a new motor and not somthing that has 100,000+ miles on it?

I see where you are coming from but your numbers are a little off. I guess all areas are different but from where I live gst/gsx's are the same price as gs's these days. If you get a gsx you already have a huge advantage and will never get that kind of traction out of a gs. A simple turbo kit for the gs is $3000 by it self, and so with your logic you have already paid as much as you would have with buying a gst/gsx. But you have the turbo kit on a weak motor and cant boost very much at all, so now your as fast as a stock gst or a little slower. Rebuilding your motor will cost another few thousand, then the tranny is the weakest link. Gs's can be fast, but with a lot more money than a turbo dsm. 100,000 miles on a 4g63 is irrelevant if it was taken care of. I see people boosting 24psi on stock bottom ends with 150k miles with no problems. Every person who has turboed a 420a motor has run into many problems, and the only ones I have seen that are actually really fast are shop cars because they have the money to support all the problems they keep running into.

ok so i look up cars in the san digo are and here is what i have found eclipse here is and ex. ex now look at the closest prices gstor gsx 1999 10,000 is the lowset i can find 2x the price. how do you figure the same yare of eclipse is the same price? so now i9 have 5000 to work with which i can get a very reliable motor and turbokit runnin under 300hp and be fine oh an i get the upgrades that i would have to to to that gsx-gst for less than the 1999 gsx/gst cost.

a friend of mine has hahns top kit on a 420A...it cost something like 12 grand....to put about 300 to the ground....with full tranny/engine/suspension/diff upgrades...

12G that is the stage V kit right because that is the top kit they have and it pushes way more than 300hp. why he swap tranny the stock on will hold up just fine up to 300hp and the suspension is fine up to 300 hp as well.

yea, im glad you guys are having fun bickering over which design is better and what not.. but im not gettin rid of my car. i still need a parts list... this subject is probably the center of the mits forum, it's rediculous... can somebody just help me with MY problem?? lol i mean for real. sent HAHN Racecraft an e-mail they said here's a good start: compression check, leak down for valves, pistons, rings, connecting rods, head struts, valve job, boar the block, turbo kit, fuel system, injectors, and cluth... does anybody care to add to this??

yes, i appreciate that everyone is giving their two cents, but he has a GS, and he is looking to build up the 420a...whether you guys agree or not, hes just hunting for some info as to suggested parts and such.

get435, that is the stage V that he is building...in a 95 sebring...300 to the wheels is his street tune, since it is his daily driver, sun, rain, or snow.

sorry get435 but if i ever saw a gs tranny hold over 300 horses with a little bit of ass kickin for more than a week without exploding in shards of metal it would be the day that my ass isnt hairy

i think that with proper driving, the tranny would hold up if it wasnt beat to begin with...i could blow the tranny in a stock yugo if i tried, and they only have like 60hp.

but to unjack this guys thread...he was just looking for any advice on how ton bulk up his current engine..

and for the record, i found out that the stock crankshaft, if in good shape, will be fine for turbo applications, and that Hahn is running a stock crank on several 11 second cars.

The stock 420a tranny is rated for 180 lbs of torq...

The person who drives a boosted 402a loves to spend money, in a wastefull manner. I got my car a year ago for 5g it ran a 18.2 stock. So far I have dropped 7200 in the car and It runs a 16.2. I haven't even installed the turbo yet.

slow, i have to ask, what exactly do you drive? my buddy who is doing the stage V hahn build in a 95 sebring, with a manual ran 16.70 with just the interior pulled...with the new tranny, stage 4 clutch, and quiaffe, and a 55 shot...he ran 15.10...

I love to see a quick 420a thats not in a eclipse or talon.

when he first got it, it was only to kick around in...

then one night we got in an arguement of whether not it would hit 60 in first gear..

it wouldnt...after that, a top end rebuilt was needed...i rode him to do a turbo build, and he said no...he built it back to stock, but in the process, he found a cheap block in case his was damaged...it wasnt, but in buying that block, he saw how cheap stuff was...he also started going to the track with me, and he was infected...he began buying parts to build the motor up...and now everything is waiting patiently in his garage for the build...on a street tune he is planning on 300 to the wheels...he also got the cladding from a 2000 sebring, and when he gets the body work done, he will have a 1-of 2000 chrysler sebring LXi turbo 4 cylinder 5 speed...

right now, just with the quiaffe and the bottle, its a fun little car to drive

a 420a boosted would be a hell of a lot faster than an awd turbo clipse....just common sense

Its obvious that a 420a isant as fast as a gsx. Not trying to say that it cant be. With enough money anthing can be fast. Do you think your cool or something for raking on a car in a post thats almost a month old? Its all been said and done, 420a's are slow, they suck. We get the picture. Grow up, act your age not the size of your weiner. If your not capable of doing that, I seriously recomend that you consider selling your car for a honda. Then you can talk all of the trash that you want, because people will expect that of you.

LOL Back to the subject at hand. Te whole post was started asking about what was required for the turbo upgrade. In addition to the things you've listen already from the company I'd suggest port and polising the head, a higher capacity feul pump and injectors, a bigger exhaust system from front to back, boost controller (Manual or electronic is purely a matter of preference). And of course you want to start looking into other areas of the car now I.E. suspension and braking. Pushin more power will require more to stop and more to hold to the road. Other than that I'd say see if you can find articles and dyno's from cars that have done different things and see how yours lines up woth them and where you want it to be.

This is the post that provoked this http://www.mitsubishiforum.com/m_26220/tm.htm

Hey there fellow eclipse owner,my name is josh and i drive a 95 gs and i have been doing minor things to my car to get it ready for the turbo project that is under way so fay i have put in 2g gsx brakes,power slotted roters all around,cold air i/t,gst oz wheels,head studs,97 front end conversion(it doesnt have n e thing to do with the turbo but looks way meanier and aggressive),walbro 255 fuel pump and regulater,and a few other thing i cant think of them atm.......Instead of buying a turbo kit check out this site and click on-mods tech and more and then click on turbo and you will see the turbo project this guy did to his gs.Why pay 3 to 4 g's on a turbo package when you can buy everything on ebay seperately for like under a 1000 bucks,that site is what gave me inspiration because all i heard from everyone is that it would be to hard or nearly impossible or expenxive to turbo charge a 420A.These motors are verry reliable and trust worthy..As for the tranny if you want to you can go to a junk yard and pick up a 98 r/t nean bc they are pretty much the strongest tranny for the 420A's,anyway the site is...Team****.com.......It lists every thing to do to boost like somewhere between 5-10 psi with the right setup.....................Josh
